The Fifth New Building Material: Metal Carved Board
Metal carved insulation board absorbs many advantages of modern wall materials at home and abroad. It is a board with heat preservation, decoration, heat insulation, environmental protection, flame retardant, weather resistance, rainproof, antifreeze, sound insulation, earthquake resistance, light weight and less land occupation. It is the most popular and best-selling new lightweight energy-saving and environment-friendly building material in the world.
There are many kinds of texture finishes such as brick pattern, spray pattern, wood grain, orange peel pattern, stripe and cultural stone pattern to choose from, and the coating will not fade for ten years. The plate specification is: 3000-6000*385* 16mm, and the standard specification is: 3800*385* 16mm.
First, the energy-saving effect is remarkable.
1. Plywood base material is 0.30mm thick aluminum-zinc plated steel plate. The theoretical life of aluminum-zinc plated steel plate is 50 years, and the recovery rate is 99.9%, which effectively realizes energy reuse.
2. The middle insulation layer is made of high-density rigid foamed polyurethane, which is the most technologically advanced and environmentally friendly insulation material in the world. At the same time, after being used at high temperature for 25 years, the thermal insulation performance of rigid polyurethane foam is reduced by less than 3%, and the protective effect of aluminum foil paper on the back is more effective, which ensures that Jiahe panel wall energy-saving system can maintain stable and good thermal insulation and energy-saving effects for a long time under various environmental conditions.
3. Combined with the unique design structure of wall energy-saving system, the phenomenon of "cold and hot bridge" is completely eliminated. Effectively avoid indoor humidity, mildew and other phenomena, achieve the effect of heat preservation and insulation, and achieve the purpose of energy saving and consumption reduction.
Second, the decorative effect is stronger.
1. The outer surface of plywood can be pressed into various textures by special technology, with diverse and vivid patterns and rich colors, which can meet different architectural styles. While beautifying the city, it also greatly improves the taste of architecture and blends with nature.
2. The plywood surface is made of high weather-resistant polyester paint layer and fluorocarbon layer, which has excellent weather resistance, corrosion resistance, acid and alkali resistance and self-cleaning, and can ensure the beautiful effect of the building facade for a long time.
3. The unique technological structure and technology of Jiahe Board can meet the design requirements of different aesthetic standards and fully bring different levels of visual enjoyment.
Third, the construction is more convenient.
1. The plywood installation system is constructed by dry hanging method, and relevant special fittings are used. The construction technology is simple, and there is no need for complicated pretreatment of the external surface of the building. Because it is not affected by the seasonal environment, the construction period is greatly shortened.
2. The construction process is dust-free and noise-free, occupying a small space, and does not produce construction waste, especially in the energy-saving transformation of existing buildings, which will not have any impact on the lives and work of residents.
Fourth, the cost performance is better.
1. When using thermal insulation materials, we should not only consider the thermal conductivity, but also measure the weight of different thermal insulation materials when they reach the same thermal resistance. The thicker the thermal insulation material, the more inconvenient the construction, the larger the volume and the greater the structural load, which indirectly leads to the increase in cost. Jiahe board is light in weight, reducing the load of wall structure, and combining with the air layer in the system in various ways to achieve double energy-saving effect, which can effectively meet the energy-saving requirements of different regions.
2. Because its surface layer is a metal surface layer, the service life of plywood is long, which effectively prevents large-scale soil erosion caused by brick burning and quarrying, and has no subsequent phenomena such as falling off, bulging and cracking, and no environmental pollution caused by radioactive substances such as ceramic tiles, stone materials and curtain walls. It is a new building material with safety, environmental protection, green energy saving and long-term benefit to human society.

building technology
1, level the uneven surface and joints of the foundation wall or fill them with 1: 3 cement mortar.
2. Before plastering the wall, proper amount of water should be sprayed for wetting, but there should be no Mingshui on the surface of the substrate.
Aerated concrete blocks can be watered one day in advance and watered twice a day to ensure their water absorption depth is above 10 mm. ..
Concrete hollow masonry can be watered one day in advance to ensure its water absorption concentration is about 5 mm
Brick walls and cement mortar bases should be watered one day in advance to ensure that their water absorption depth is about 10mm, and can be watered again before construction.
3. Glass fiber grid cloth should be pasted on the junction and corner of different base materials of the wall, and the lap width should be not less than 100mm from the junction.
4. Preparation of slurry
Primer plaster: It can be mixed manually or mechanically. Gypsum mortar with a certain binder-sand ratio should be stirred evenly as required and used immediately.
Plastering surface layer: firstly, add water into the mixing barrel, and then add powder to mix evenly, and then use it.
The mixing water of mud must be clean and impurity-free drinking water.
5. Construction operation
During construction, the plastering route and sequence should be determined first to ensure the continuous operation of the project.
According to the flatness and decoration requirements of the wall foundation, standard reinforcement should be set.
When plastering on a relatively flat wall, the plastering thickness is generally around 8mm, which can be completed at one time or layered construction. When the plastering thickness exceeds 8mm due to uneven wall surface or other requirements, layered construction shall be carried out. The lower layer shall be carried out after the initial setting of the upper cement slurry; When the plastering thickness is greater than 35mm, strengthening measures should be taken.
The bottom slurry should be calendered before the final set (when it is pressed with fingers at the scene, it is slightly dry and hard, and fingerprints can still be pressed out), pressed on the title with a scraper, leveled up and down, left and right, and then calendered with gypsum.
The finish should be carried out after the final setting of the bottom plaster, and the thickness is generally 2-3mm, which can be completed at one time. Surface calendering shall be carried out before final setting.
Clean up when plastering, and the mortar scraped off when finishing shall not be recycled.
Matters needing attention
The construction temperature of anhydrous plastering gypsum should be controlled at 0-40 degrees Celsius.
It is not advisable to add water to the solidified slurry.
Non-condensing cement slurry must be used in winter construction.
It is not suitable for use outside the wall or in an environment that is often exposed to open water.
Plastering should be avoided in the environment where the wall temperature changes greatly (for example, direct sunlight is used to construct the wall in summer).
Transportation and storage requirements: sun protection and moisture protection. Shelf life: 6 months
