Anti-corrosion wooden floor is the name of the finished product of ordinary wood after anti-corrosion treatment. After anti-corrosion treatment, the performance of ordinary wooden floor is greatly improved, achieving the functions of anti-corrosion, anti-mildew, anti-moth and anti-termite.
Application of anticorrosive wood floor
The outdoor wooden floor is specially used for outdoor environment, and can be directly used in the environment in contact with water and soil. It is the first choice material for outdoor anticorrosive wooden sheds such as outdoor wooden floors, garden landscape floors, outdoor wooden platforms, terrace floors and outdoor wooden plank roads.
Production technology of anticorrosive wood floor
(1) vacuum high pressure impregnation
This process is the key step of anti-corrosion treatment. Firstly, the physical process of pumping preservatives into wood is realized, and at the same time, the chemical reaction process of some effective components of preservatives with starch, cellulose and sugar in wood is completed, thus destroying the living environment of bacteria and insects that cause wood decay and effectively improving the outdoor anticorrosion performance of wood.
(2) High temperature characteristics
At high temperature, the preservative will continue to penetrate into the wood as evenly as possible, and the chemical reaction process between the effective components of the preservative and starch, cellulose and sugar in the wood will continue to be completed. Further destroy the living environment of bacteria and insects that cause wood rot.
Advantages of anticorrosive wood flooring
(1) Nature, environmental protection and safety (natural color of wood, slightly turquoise);
(2) Anti-corrosion wood is anti-corrosion, mildew-proof, moth-proof and termite-proof;
(3) In order to improve the stability of wood, anticorrosive wood is more important to protect outdoor wood structure;
(4) Anti-corrosion wood is easy to paint and color, and can achieve beautiful effect according to the design requirements;
(5) It can meet all kinds of design requirements, and is convenient for making anticorrosive wood for various garden landscape products;
(6) Anti-corrosion wood is particularly effective when it comes into contact with wet soil or hydrophilic substances, and can be used in various outdoor climatic environments for more than 15-50 years.
Disadvantages of anticorrosive wood flooring
(1) Corrosion resistance
Chemical agents are used to kill decaying bacteria, so as to achieve the anti-corrosion effect and prolong the service life of wood. However, the agent is easy to lose, thus reducing the service life;
(2) Not environmentally friendly
First, the use of chemical agents in the production of chemical preservative wood causes pollution to the environment; Secondly, chemically preserved wood is in contact with human body and livestock during use, which is harmful to human health;
During the use of chemically preserved wood, chemical substances are lost in the use environment because of rain erosion, which causes pollution to the surrounding environment;
Chemical preservative wood needs to be recycled after use, otherwise it will pollute the surrounding environment.
(3) High water content
Because chemicals are impregnated in the process of pressurization, at the same time, water is impregnated into wood. However, preservative wood production enterprises generally do not adopt secondary drying, so the moisture content of wood itself is high;
(4) easy to deform and crack
Due to the high moisture content of anticorrosive wood, with the change of service environment, wood expands and contracts when wet, resulting in internal stress deformation and cracking.
(5) uneven color, dull
Because chemicals are immersed in wood, wood looks like the color and green of chemicals. Due to the different dosage of chemicals, the wood color is uneven, the color difference is large, and the wood is dull.
(6) easy to change color
With the loss of chemicals, the color of wood becomes lighter and then becomes gray;
(7) Not easy to recycle
Because chemical preservative wood contains chemicals harmful to human body and livestock, it needs special treatment after use, which increases the use cost. In addition, chemical preservative wood cannot be recycled, which wastes wood resources.
Composition of anticorrosive wood floor
Chemical anti-corrosion wooden floor The floor with preservatives is called chemical anti-corrosion wooden floor. The main preservatives added to chemical anticorrosive wood floors are CCA, ACQ and CAB. CCA is mainly composed of copper and arsenic, ACQ is mainly composed of ammonia-soluble alkylamine copper, and CAB is mainly composed of copper file.
Specification for anticorrosive wood flooring
In order to reduce the influence of moisture content on outdoor anticorrosive wood flooring, the width of outdoor anticorrosive wood flooring is generally less than 150mm, the length is mostly 3000mm and 4000 mm, and the standard thickness is 15mm, 28mm, 38mm and 45mm.
Procurement of anticorrosive wood flooring
(1) What's the price of the anticorrosive wood floor?
Different brands, different styles, different quality and different technologies will also have different prices. Generally speaking, the price of high-quality anticorrosive floor is between 65438 yuan and 020 yuan-one square meter in 300 yuan.
(2) The brand is more formal
Choose anticorrosive wood flooring, of course, also need to choose a brand, more formal products, so as to have a great guarantee in quality and environmental protection. At present, in order to select high-quality anticorrosive wood, it is suggested to buy it in the famous large-scale building materials market, which is safe and reliable.
(3) The basis for judging the quality of anticorrosive wood flooring.
Safety grade: The preservative of anticorrosive wood floor should be highly toxic to all kinds of bacteria and insects that harm wood, but at the same time, it should be low toxic or non-toxic to people and animals and will not cause pollution or damage to the environment. With people's concern for the environment and sustainable development, efficient and environmentally friendly composite wood preservatives have received due attention.
Harmful damage to wood: after anti-corrosion treatment, the mechanical strength, good texture and pleasing color of wood should not affect its performance.
Persistence and stability: Wood preservatives should have relatively stable chemical properties. After wood is injected, it is not easy to volatilize and lose, and it maintains its due toxicity for a long time.
Construction technology of anticorrosive wood floor
(1) mobile paving method
Stainless steel cross screws are needed to connect the front of the anticorrosive wood with the keel; Then the keel is fixed on the opposite side of the board with screws, and several pieces can be combined into a whole without destroying the structure of the ground, and can be freely disassembled and cleaned.
(2) Fixed paving method
This requires the use of expansion screws. Similarly, the keel is fixed on the ground with a layer of wool, and the iron expansion pipe should be coated with antirust paint before laying anticorrosive wood.
(3) Hanging paving method
This method needs to level the keel on the ground first, because it can be connected into a frame or a tic-tac-toe structure; Then, lay anti-corrosion wooden floor. This structure is to fully maintain the air circulation between the anticorrosive wood and the ground and prolong the service life of the wooden structure foundation.
Brief introduction of wood-plastic flooring
Wood-plastic flooring is a new type of environmentally friendly wood-plastic composite product. Lignin produced in the process of producing medium and high density fiberboard was added with recycled plastic to make wood-plastic composite material, and then extruded to make wood-plastic floor.
Use of wood-plastic flooring
The main materials of wood-plastic outdoor floor are PE and wood powder or bamboo powder. After adding additives, high-speed mixing, granulation, and then extrusion into profiles with an extruder. This floor can be used for outdoor platforms such as gardens and villas.
Production technology of wood-plastic flooring
There are many ways to make wood-plastic composites by compounding wood and plastics (thermoplastics and thermosetting plastics), and the principles are different. When thermosetting resin is used, a certain form of wood raw materials and resin liquid are generally mixed evenly at normal temperature and pressure, and then cured and molded at a certain pressure and temperature according to the properties of resin and the requirements of composite materials or their products, and then cross-linked polymerization is initiated, and then the products are obtained through post-treatment such as modification.
When thermoplastic or resin is used, wood (fiber, powder, shavings, etc. ) Generally, it is mixed with plastics and processing AIDS at room temperature, then the mixture is heated to high temperature to melt the plastics and fully mix with wood, and then the flowable wood-plastic mixture is pressure molded (usually by extrusion, injection, hot pressing, etc.). ), cooling and curing to obtain wood-plastic composite products.

The installation is simple, the construction is convenient, and a particularly complicated construction process is not needed, thus greatly saving the installation time and cost. No special maintenance is needed, so the cleaning is very convenient and the later maintenance cost is saved.
Disadvantages of wood-plastic flooring
(1) Wood-plastic flooring is fragile, with high moisture content, insufficient toughness and weak impact resistance. This is determined by its internal structure and production technology.
(2) In order to save costs, some manufacturers will reduce the use of antioxidants and other related additives, or reduce the amount of wood fibers such as wood flour, which is prone to engineering accidents such as serious fading and fragile materials.
(3) If the external environment temperature of wood-plastic composite products changes greatly, the surface layer and the interior are unevenly heated, which will easily lead to expansion, contraction and deformation, and the life of wood-plastic flooring will be shortened if it is used for a long time.
(4) Wood-plastic flooring will shrink, some wood-plastic flooring products will fade, the surface of wood-plastic flooring will be too smooth, and it will slip when it is wet.
Wood-plastic flooring specifications
The specifications of wood-plastic flooring can be customized at will. Commonly used wood-plastic flooring specifications include dozens of specifications such as PA 140*25, PA 145*30, PA 135*25 and PA 125*25. The specification of commonly used wood-plastic keel is 2000*40*25 (length * width * thickness, unit: mm). The laying directions of the wood-plastic floor and the wood-plastic keel are perpendicular to each other, and the laying distance between the two wood-plastic keels is generally between 350 mm and 400 mm, so as to ensure that the wood-plastic keel is supported at the longitudinal splicing position when the wood-plastic floor is laid.
Buy wood-plastic flooring
(1) surface
Good wood-plastic flooring has smooth and shiny surface and side, fine wood powder particles, uniform size, no fine cracks and dense texture on the cut surface.
(2) packaging

Although the cheap floor is cheap, it has a short service life and may not be sold after sale.
Construction technology of wood-plastic floor
(1) Preparation before construction of wood-plastic floor. Before construction, ensure that the concrete base of the construction site is smooth. If there is any problem, it should be repaired before laying.
(2) Fixing the wood-plastic keel, and directly fixing the wood-plastic keel on the ground with an expansion pipe. The distance between the fixing points of plastic expansion pipes is 500mm~600mm, and the nut should be lower than the surface of wood-plastic keel, and the wood-plastic keel should be flat as a whole.
(3) The center distance of the keel should be controlled between 3 10-4 10mm, and the butt joint at the end of the keel should be around 10mm to facilitate drainage. At the same time, the end seams between rows of keels should be staggered and not in a straight line. Allowable error of keel spacing
(4) When the ground construction conditions at the grass-roots level on the construction site are poor and the theme structure cannot be stabilized, steel keel must be used instead of wood-plastic keel. The newly used galvanized steel should be removed, and the welding slag in the back seat should also be removed to prevent rust.
(5) The size of the floor splicing gap should be reasonably determined according to the environmental temperature and humidity, floor length, floor moisture content, laying area and other factors when the wood-plastic floor is installed.
Brief introduction of carbonized wood floor carbonized wood floor
Carbonized wood floor is a kind of high-temperature homogeneous carbonization treatment of wood without adding any chemical agent, which makes the wood surface have dark brown aesthetic effect and has the functions of anticorrosion and biological invasion prevention.
Application of carbonized wood floor
Low moisture content, not easy to absorb water, stable material, no deformation, complete degreasing, no grease overflow, good heat insulation performance, simple construction, convenient brushing and no special smell. It is an ideal material for indoor and sauna rooms and has become a new trend of bathroom decoration. Its corrosion resistance, moth resistance, deformation and cracking resistance and high temperature resistance have also become ideal materials for outdoor swimming pool landscape.
Production technology of carbonized wood floor
The carbonization process of carbonized wood is divided into the following three processes:
(1) heating and high-temperature drying.
With the heating, the kiln temperature quickly rose to 100℃
Then when the temperature rose to 130℃ and remained stable, the wood kiln began to dry, and the water content almost dropped to zero.
(2) heat treatment
Once the drying of the kiln is started, the temperature in the kiln should be raised to185 C to 215 C, which will last for 2-3 hours according to the final use of the carbonized wood.
(3) Air conditioning and humidity adjustment
The final stage is to cool down with a water spray system; When the temperature drops to 80-90℃, humidification is started again, so that the water content of wood reaches the available level of 4-7%.
Advantages of carbonized wood flooring
(1) Improvement of durability and corrosion resistance: During carbonization, complex chemical reactions occurred in the floor components, which changed some components of the floor, reduced the nutritional components of floor rot fungi, and inhibited the growth of fungi in the floor from the food chain. Therefore, the corrosion resistance and weather resistance of carbonized floor are obviously improved, and it has the functions of anti-corrosion, anti-termite and anti-fungus;
(2) Environmental protection: the environmental protection drying carbonization process is different from the chemical modification of the floor. The floor carbonization treatment is a pure physical technology, which only involves temperature and water vapor in the floor carbonization process without adding any chemical agents;
(3) Improvement of dimensional stability: The floor is heat-treated at high temperature (160-230℃). By reducing the concentration of hydroxyl in the floor components and the hygroscopicity and internal stress of the floor, the exchange ability between carbonized floor and external water is significantly reduced, and the wet expansion can be reduced by more than 50%, which greatly improves the dimensional stability of the floor, thus greatly reducing the deformation, shrinkage and wet expansion of the floor caused by changing water in use;
(4) Moisture-proof enhancement: After carbonization heat treatment, the water-absorbing machine of the floor has changed. With the increase of treatment temperature, hemicellulose with strong hygroscopicity is degraded during treatment, which reduces the hygroscopicity of the floor and the hydrogen bond between water molecules and floor molecules, thus greatly reducing the hygroscopicity and water absorption of the floor and keeping the carbonized floor with low moisture content in humid air. The equilibrium moisture content of carbonized floor is 40% lower than that of non-carbonized floor. The equilibrium moisture content of carbonized floor is also low, and the moisture content of floor can be kept at 6% when it is used in greenhouse. Therefore, carbonized floor products are not easy to deform and crack, and can be applied to dry and turbid environments.
(5) Color: The color of the carbonized floor is the same inside and outside, and the color uniformity and durability can also be guaranteed by the whole board. The color of carbonized floor is physical coloring, which will not change with time, and the decorative effect of carbonized floor is consistent (it can be used as antique solid wood floor);
(6) Easy maintenance: The resin and some inclusions of the carbonized floor are separated out during carbonization treatment, so there is no oily component such as resin on the surface of the carbonized floor, which is easy to coat. At the same time, because the carbonized floor has the advantages of corrosion resistance, good stability and moisture resistance, it is quite easy to maintain in daily use;
(7) Thermal conductivity: Good thermal conductivity, skin contact with carbonized wood will not have any discomfort, completely bid farewell to the coldness of traditional tiles. Carbonized floor is an ideal material for modern interior decoration.
Disadvantages of carbonized wood flooring
(1) Wood without moisture is more brittle than wood with moisture. Although the carbonized floor is firm, it has lost its original elasticity. Feet and touch are not as soft and comfortable as other floors;
(2) After high-temperature drying, the carbonized floor lost its original flavor. Although the carbonized floor has no peculiar smell, it has no natural fragrance of wood;
(3) The carbonized floor retains the natural texture of wood, but loses its natural color. Carbonized floors are usually dark, and the color is not as bright as other floors.
(4) It is suitable for the desert climate in the north, and the carbonization technology is difficult, and the whole industry can really do a good job of carbonization.
Specification for carbonized wood flooring
All sizes can be customized. Conventional sizes are: 100× 100, 95×95, 15*95, 2 1*95, 25× 150, 25×300 and 30× 300.
Carbonized wood floor purchase
Deep carbonized wood is a kind of wood treated by high temperature carbonization technology at about 200 degrees. Because its nutrients are destroyed, it has good anti-corrosion and insect-proof functions, and because its water-absorbing functional group hemicellulose is recombined, the product has good physical properties. Deep carbonized anticorrosive wood (hereinafter referred to as deep carbonized wood) is relative to surface carbonized wood. From the appearance, the inner and outer colors of the surface carbonized wood are different, and the carbonized layer is as thin as the surface paint layer.
The surface of carbonized wood is golden to brown! After the carbonized wood is cut, the section color is the same.
Construction technology of carbonized wood floor
(1) Treatment of wood structure base: In the process of design and construction, air circulation between carbonized wood and the ground should be fully maintained, which can effectively prolong the service life of wood structure base.
(2) During manufacturing and installation, there should be a gap of 0.2- 1CM between carbonized wood (the gap size should be determined according to the moisture content of wood, and it should not exceed 0.8CM when the moisture content of wood exceeds 30%) to avoid the swelling of carbonized wood in rainy days.
(3) For square columns with a thickness of more than 50mm or more than 90mm, a groove can be opened in the center of the back to reduce cracking.
(4) Hardware shall be made of stainless steel, hot-dip galvanized or copper to avoid rust and corrosion in the future. Please drill holes in advance when connecting and installing to avoid cracking of carbonized wood.
(5) Make full use of the existing size and shape, and paint and outdoor protective coating should be applied to the damaged parts; Because carbonized wood itself is a semi-finished product, the rough part can be polished again after the moisture content of wood drops below 20%. If you want to have a better effect, you can also apply outdoor protective paint after the surface is cleaned. In case of rainy days, it is best to cover it with plastic sheets first, and then brush the outdoor protective paint after it clears up.
(6) After the surface of carbonized wood floor is coated with external protective coating or oily coating, the effect is the best, so as to avoid people walking or heavy objects moving within 48 hours, so as not to damage the formed protective film on the surface of carbonized wood floor. If you want to achieve better antifouling effect, the surface layer should be treated with two special outdoor varnishes when necessary.
