The first is to ask for a quality inspection report to understand the quality of the product. The second is to check the appearance quality, carefully check whether there is oil or watermark on the front of the gypsum board, whether the front of the gypsum board is flat, whether there are more and deep corrugated grooves and scratches. The third is to check the degree of bonding between the facing paper and the core. It is necessary to randomly find a few sheets, and use the gypsum core and the face paper to expose the facial tissue at the end. If the exposed facial tissue paper is peeled off between the layers, it indicates that the protective paper of the sheet is bonded with the gypsum core. Good; if there is a tear between the exposed facial paper and the plaster core layer, it indicates that the sheet is poorly bonded. The fourth is to check the thickness. Check whether the thickness is up to standard and meet the national standards.

The reason why the cutter head can cut is because it contains diamond, and diamond is the most important part. A hard substance that rubs and cuts the workpiece in the cutter head. The diamond particles are wrapped by metal inside the cutter head.
Sintered diamond saw blade: divided into cold pressing sintering and hot pressing sintering, which are pressed and sintered.
