Problems solved by technology

[0002] With the gradual increase of laboratory equipment at present, the physical and chemical board used in the laboratory is used more and more widely as an indispensable material. Phenolic resin has high bonding strength, water resistance, heat resistance, wear resistance and good chemical stability. It is widely used in the physical and chemical board industry due to its advantages, but it has disadvantages such as high cost, high curing temperature and long curing time. The current physical and chemical boards are increasingly unable to meet market demand in terms of corrosion resistance, heat resistance and service life.
