Explain the advantages and disadvantages of each experimental bench top material
Nowadays, in order to extend the service life of the experimental bench, the materials of the experimental bench are also divided into many types, and different types of benchtop materials also have their own advantages.
1. Solid physical and chemical boards are made of different papers and anti-corrosion materials. There is only a transparent film on the surface. This transparent film has good anti-corrosion ability. However, since this material is made of paper, it will absorb some moisture and moisture from the air during use, causing the table to deform. Moreover, the solid core physical and chemical board table cannot be in direct contact with flames. During the contact process, it may cause the experimental table top to burn, etc.
2. Epoxy resin boards are baked with different curing agents. This material will automatically burn after reaching a specific high temperature, and the surface has not been specially treated, so it is easily damaged and scratched during use.
3. Ceramic countertops contain different soil textures, and the surface is enamel treated. The countertops fired at high temperatures can avoid damage by various strong acids and alkalis, and will not deform. Due to the specificity of its material, it is particularly suitable for use in some specific laboratory environments.
