Waterproof gypsum board
It means that the water absorption of this kind of slate is 5% when tested according to American ASTM standard, that is, it can be used in high temperature areas, such as toilets, shower rooms, kitchens and so on. The board is made by adding a certain amount of waterproof agent into gypsum core material, so that gypsum itself has certain waterproof performance. In addition, gypsum board paper is waterproof, so it is a better board with wider uses. However, this board should not be directly exposed to humid environment, nor should it be directly immersed in water for a long time.
fire prevention plasterboard
It means that this kind of board keeps its structural integrity (in building structure) for a long time when it is on fire, so as to block the spread of flame. Glass fiber and other additives are added in the production process of plate, which can effectively enhance the integrity of plate in case of fire.
High strength gypsum
Gypsum dihydrate was steamed in saturated steam at 1.3 atmospheric pressure and 124℃, and the α-type semi-hydrated gypsum was ground into high-strength gypsum. Due to decomposition under high pressure, high-strength gypsum has coarse particles and small specific surface area, and the plasticizing water demand of gypsum slurry is very small, about 35-45%, so the porosity after hardening is small and the strength is high (up to 40MPa in 7 days).
High strength gypsum is suitable for high strength plastering engineering. Decorative products and gypsum board. Waterproofing agent can be used in high humidity environment. Non-shrink adhesive made of organic adhesive.

Waterway construction
Galvanized pipes: Galvanized pipes are mostly used in old houses. Now the iron pipes for gas and heating are also galvanized pipes. After several years of use, a large number of rust scales have been produced in the pipeline. The yellow water not only pollutes the sanitary ware, but also is mixed with bacteria that breed on the unsmooth inner wall. Corrosion leads to high content of heavy metals in water, which seriously harms human health. In 1960s and 1970s, developed countries began to develop new pipes and gradually banned galvanized pipes. China Ministry of Construction and other four ministries and commissions also issued a document explicitly prohibiting galvanized pipes from 2000. At present, galvanized pipes are rarely used for cold water pipes in newly-built residential areas, and galvanized pipes are used for hot water pipes in some residential areas.
UPVC pipe: In fact, it is a kind of plastic pipe, and the joints are generally glued. UPVC pipe has poor frost resistance and heat resistance, so it is difficult to be used as hot water pipe. Because its strength can not meet the pressure requirements of water pipes, cold water pipes are rarely used. In most cases, PVC pipes are suitable for electric wires and sewage pipes. In addition, in recent years, the scientific and technological circles have found that phthalein, a chemical additive that can soften PVC, has a great influence on the kidneys, liver and testicles in the human body, which will lead to cancer and kidney damage, destroy the human functional reconstruction system and affect development. So I advise you not to buy it.
Aluminum-plastic pipe: Aluminum-plastic composite pipe is a popular pipe in the market. At present, Rifeng and Jinde are well-known in the market. Because of its light weight, durability and convenient construction, its flexibility is more suitable for home decoration. Its main disadvantage is that when it is used as a hot water pipe, long-term thermal expansion and cold contraction will cause dislocation of the pipe wall and leakage. Many residential areas in Beijing use aluminum plastic pipes. In Guangdong, Shanghai and other places where the decoration concept is relatively new, aluminum-plastic pipes have gradually lost their market. At present, aluminum-plastic pipes are still active in the Beijing market. I believe that in the near future, the aluminum-plastic pipes in Beijing market will also face elimination.
PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages. It can be used as both a cold water pipe and a hot water pipe. PPR pipe is becoming a popular material because of its non-toxicity, light weight, pressure resistance and corrosion resistance. At present, it is rarely used in decoration projects in Beijing. PPR pipes are not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. The interface of PPR pipe adopts hot melting technology, and the pipes are completely fused together. Therefore, once the installation and pressure test pass, it will not age and leak for a long time like aluminum-plastic pipes, and PPR pipes will not scale. At present, PPR pipes are widely used in cold water pipes and hot water pipes of some high-grade houses and apartments in Beijing. PPR pipes are called green and advanced water supply materials.
Copper tube: Copper tube has the advantages of corrosion resistance and sterilization. It is a first-class product in water pipes. There are two ways to connect copper pipes: clamping and welding. Jacket, like aluminum-plastic pipe, has the problem of aging and water leakage for a long time. Therefore, in Shanghai and other places, users who install copper pipes mostly use welding, that is, welding the joints together through oxygen, so that they will never leak like PPR water pipes. One disadvantage of copper tubes is that they conduct heat quickly. Therefore, the hot water pipes produced by well-known copper pipe manufacturers such as Shanghai Sanjing and Baoyang are all covered with plastic and foaming agent to prevent heat dissipation. Another disadvantage of copper tube is its high price. Few residential water supply systems are made of copper pipes, which I am afraid will only be seen in export apartments and high-grade villas. If you plan to change the water pipe and think the copper pipe is good, it is recommended to use welded joints. Some netizens mentioned that oriental home Xisanqi Store has British IBP copper pipes, which I have never used. You can check them.
Stainless steel pipe: it is a very expensive water pipe, which is difficult to construct and rarely used. Its performance is similar to that of copper tube.
Plug: a plug used to close the water outlet after the water pipe is installed. Please remove the faucet when installing it!
Mixing valve: The mixing valve is a valve for mixing hot and cold water. In fact, the valve itself cannot be mixed, but the hot and cold water pipes are connected, which plays a role in mixing.
The number before the water pipe specification indicates the outside diameter. The latter number indicates the wall thickness of the pipe.
For example, ￠25X2.8(0.5) and 655x3.5(0.6), the former is a cold water pipe and the latter is a hot water pipe.
Large core plate
The large core board is a special sandwich plywood, which is made up of wood strips with the same thickness and different lengths arranged in parallel and closely spliced, and generally has a five-layer structure. The vertical bending and compressive strength of large-scale core plate is poor (according to the direction of core material), and the transverse bending and compressive strength is high.
Art cover
Decorative panels are commonly known as panels. It is a decorative board with one-sided decoration function, which is made by precisely planing solid wood plates into thin veneer with a thickness of about 0.2mm, using plywood as the base material and adopting the gluing process. It is a special way of splint, with a thickness of 3 cm. Decorative board is a kind of advanced decorative material which is different from mixed oil at present.
splints
