1. Select high quality base material, adhesive and construction tools.
a. At present, the common base materials in the market are blockboard, MDF, particleboard and density board. When selecting, please pay attention to the water content, flatness and other parameters of the base material, especially the substrate with surface treated by sanding;
b.防火板施工史较常用的胶有以下几种：PVAC白胶、Neoprene Solvent 强力胶、热固型树脂胶、脱水脲醛胶（工业类）、粘贴用胶择必须选择正牌优质胶；
b. The common adhesives used in the construction history of fireproof board are as follows: PVAc white glue, neoprene solvent strong adhesive, thermosetting resin adhesive, dehydrated urea formaldehyde adhesive (industrial type), and genuine high-quality adhesive must be selected for pasting;
c. Construction tools: due to the hard texture of the fireproof board, good quality tools are needed to cooperate with the construction. Carbon steel tools are used as far as possible, especially the table top saw blade and trimming machine edge. Only when they are made of steel and carbon can they be clean and smooth. Cut section without notch. When using hand tools, it is better to use hand tools with metal handle, such as manual woodworking saw.
2. Construction process
a. Cutting: cut the fireproof board into the required size, and then leave 1 / 4 inch (6 mm) for trimming. Note that the saw teeth enter from one side of the color board, so as to avoid the gap in the cutting section. If you use a blade to cut the fireproof board, you must also feed the knife from one side of the color paper, and then cut it like glass to make it clean and smooth Without notch.
b. Gluing: evenly apply strong glue on the back of fireproof board and the surface of base material. If the surface of base material is very uneven or water absorption is very strong, it is necessary to apply glue twice by hand to make the surface completely covered with glue. Pay attention to the reasons of season, climate and region during construction. The volatilization time of each brand of super glue will be different. According to the use suggestions of super glue, combined with the actual operation and construction spare parts, the volatilization time is determined. For example, when using dehydrated urea formaldehyde glue and white milk adhesive, it is necessary to pressurize for more than 12 hours at room temperature of 25-30 ℃.
c. Pasted board: when it is dry enough to not stick to the market, carefully place the fireproof board on the base plate. If the pasted area is very large, it is better to place the fireproof board on the base plate with wooden strips, and then put the fireproof board on the base plate. After alignment, pull out the wood strip, and press the fireproof board onto the base plate step by step. Then use the flow roller or cloth to press evenly, while avoiding residual air in it.
d. Correction: when the above pressurization work is done, use a trimming machine or a 10 degree edge to cut off the excess edge, and then file the seam more smoothly with a more convenient file. Please note: only file down, never file back and forth, so as to avoid uneven and smooth cutting section! Excess glue should be cleaned up with a small cloth and solvent. In this way, the whole construction process is completed.
e. Construction environment requirements: it is generally recommended that the fire-proof board and base plate should be placed in the same environment for 48 hours, the humidity should be 45%, not higher than 80%, and the temperature should not be lower than 18 ℃.
