Q:Bookcase with what the best plate
It is best to use a fir fingerboard for a bookcase and a wardrobe. Environmental protection and beautiful, direct brush on the varnish, very kind of living in the pastoral fresh gas. But there is little change that is. Wardrobe doors need to use woodworking board or three-layer composite finger plate to do. And the bare part of the backplate is reinforced with white pine keel. This will avoid cracking. Another kind of cracking may refer to the board failure, moisture content is relatively high. Therefore, it is recommended that you use a good quality plate, home improvement commonly used brands are Moganshan and bunny. You can also use Jiangxi 100 source. The quality of the king coconut is not evaluated. I wish you a pleasant decoration.
Q:Is it good to use the fireproof sheet?

After the fire treatment of water-resistant plaster board can be used for the humidity of the room walls, such as the bathroom, kitchen, bathroom and other tiles, metal plate, plastic tile wall lining.
Q:How to degrease the wood
High temperature drying method High temperature drying is considered to be a more effective degreasing method. Cech [2] has done a degreasing test of Korean pine wood, using a high-temperature drying method to reduce the average rosin by 274% and turpentine by 40 1%. If high temperature drying The rosin can reduce the rosin by 30% and the turpentine can be reduced by 65%. This method is mainly to remove the turpentine of the resinous acid that dissolves the solid because the boiling point of the turpentine is about 1 50 to 2 3 0 ° C, If the coexistence with water can be reduced to below 100 ℃. [3]. Turpentine volatile at high temperatures, and under high temperature steaming conditions to reduce the boiling point of turpentine, while high temperature steam to improve the permeability of wood, can be effective To evaporate the turpentine component, the remaining solid rosin after treatment will not exudate. High temperature plus steam combined dry is the most effective practical method, it does not need to add any equipment only the original drying kiln, so less investment , But many people use it, but some people think that after the role of high temperature and humidity, dry wood after the pine wood surface dark gray, dim, lost the original natural wood color, processed into products after the tan.
Q:What is the difference between steel sheet and coil?
Coil is the factory roll because the length is long to roll up with C said, such as: 2.75 * 1500 * C Tablet is the factory in the hot-rolled production line before the cutting plate stability of the specifications cut into a board, such as: 2.75 * 1500 * 6000
Q:Plate and line joints at the crack causes, with morning sun water paint can improve it
I can use the morning sun water-based wood paint, like a wooden furniture clothes, not only cleverly cover up the wood surface of the insects, knots, color and other defects, but also to highlight the beautiful texture of wood, while Play the role of protection of wood. Recommend you try, very safe
Q:What is the board made of wood chips

Q:Plate furniture formaldehyde release national standard is
0.08 bar. Furniture, what is more or less taste, so the distribution of formaldehyde will be more, this is also normal. Select the time to try to choose the sample, the placement of a long time there is no, or you can buy more time to smell, if you have bought back, put it, conditionally with some herbs to break down formaldehyde, Is no secondary pollution, no harm.
Q:What are the PCBs
Flame Retardant Copper Foil Phenolic Paper Laminate. IPC4101 detailed specification number 02; Tg N / A;
Q:Which furniture plates are suitable for painting and stamping panels?
Nine PCT board, because he has lines can also be sprayed, out of the effect is very good
Q:Home decoration need to do wardrobe, what plate is the most environmentally friendly?
MDF is a good choice Is the lignocellulosic fiber or other plant fiber as raw material, after cooking into small fibers by adding the right amount of adhesive, under a certain temperature and pressure under pressure from the suppression. 1, high density, high strength. At present, MDF has become the main material of most wardrobe manufacturers.   2, the particle board: the saying goes "particleboard", the wood processed into small particles shavings and add appropriate amount of glue, in a certain temperature and pressure from the suppression. Density is not high, the intensity is small.
