Selection of medium density fiberboard
1. Check whether the thickness and density are uniform, whether the corners are damaged, whether there are delamination, bulging, carbonization, etc., and whether there is a soft part.
2. When conditions permit, a small piece of medium density fiberboard can be sawed in water with a water temperature of 20 ° C for 24 hours to observe the thickness change, and observe whether there is a small drum kit on the board surface. The thickness varies greatly, and there are small drums on the board surface, indicating that the board surface is poor in water resistance.
3. Select medium-density fiberboard with low release. When using olfactory smell, choose medium-density fiberboard with low odor. Because the smell is bigger, the higher the formaldehyde emission, the greater the pollution.
1) Sharp cutting and processing;
(2) Diamond cutting pieces have high rigidity, high strength and long service life;
(3) The ultra-thin diamond cutting piece has high precision, which can be used for slotting machine cutting, and the incision is smooth without collapse;
(4) The continuous cutting of Valin diamond slices does not slip and does not appear the phenomenon of blade passivation;
(5) The diamond cutting slot is narrow, which can greatly improve the utilization rate of precious raw materials.
