1. Solid wood board has high environmental protection performance and not easy to deform. The disadvantage is that furniture made of solid wood board must be careful can not be irradiated by sunlight and not too humid, otherwise it will easy to cracking. 2.  Particle board  is a artificial board, which is made by pressing wood and sawdust according to the specifications and under certain conditions, its surface looks like a honeycomb. 3.  Fiber board , also known as density board, it is a common board. 4. Wood board, the board direction is vertical or horizontal, the vertical texture is slightly less compressive than the horizontal texture. 5. Integrated board, use solid wood board is as the core board, then painted wax oil on the surface, which can enhance wear resistance and corrosion resistance for board.

T he   wooden formwork   consists of panel and support system. The quality of the formwork is related to the quality of the concrete project. According to the form and characteristics to select the appropriate form of template of the structure in order to achieve good technical and economic effects. Timing for removal of wooden formwork 1. The non-load-bearing side formwork should be able to maintain its surface and edges and corners without damage due to formwork removal. Generally, it can be removed after 3 days. 2. The load-bearing formwork should be removed after the concrete becomed strength. 3. The concrete strength of the slab formwork reaches 75% (ie 20 days) 4. The concrete strength of the bottom formwork of the single beam reaches 100% (ie 25 days) 5. The concrete strength of the cantilever beam formwork reaches 100% (ie 28 days) 6. When the load-bearing formwork is removed and the upper part of it is subjected to construction loads, it must to add temporary supports. ZMADTO

According to the national standard,   MDF   can be divided into E0, E1 and E2 by the free formaldehyde content. E2-grade formaldehyde emission is ≤5mg/L; E1-grade formaldehyde emission is ≤1.5mg/L, which can be used for interior decoration directly; E0-grade formaldehyde emission is ≤0.5mg/L. When consumers buy MDF, they should try to buy products with low formaldehyde emission, which are safer. ZMADTO Plywood Co.Ltd.  is professional manufacture in plywood. We supplier all kind of film faced plywood, particle board, MDF board in all kinds and size, if you have any require, welcome to call us.

Cylindrical formwrok  is made of plywood and offers great coverage with few splices and seams. The cylindrical formwork has good structural performance and can be cut arbitrarily according to the actual size, which reduces the difficulty of construction and shortens the construction period. When the cylindrical formwrok is supported, the following matters must be paid attention to ensure the quality of project. 1. In order to protect the cylindrical formwork, four pcs 5*10cm wooden squares are added vertically around the formwork after the steel strip is installed. The wooden squares are fixed with 4 steel pipes, and the distance between the upper and lower steel pipes is kept at 100cm, which can protect the wooden formwork. It can buffer the pressure of the vibrating rod, also conducive to the vertical positioning of the formwork. 2. When the column intersects the wall, the joint must be properly treated, otherwise it may cause water seepage. Therefore, if the column is poured separat
