Solid core corrosion-resistant physical and chemical board is made by thickening kraft paper on the core material and pressing it under high temperature and high pressure. The thickness is more than 3mm. It can be directly made into table or cabinet board without adhering to the base material. The unique structure of fumeihua corrosion resistant physical and chemical board is: ① chemical film, ② surface paper, ③ color paper, and ④ special kraft paper (multilayer).
Who is better than epoxy resin
The market of decorative materials is similar. Although there are many kinds of decorative materials, there is always a comparison between the two materials. Many users are more concerned about who is better than the solid core physical and chemical board and epoxy resin? Today, we will talk about it in a comprehensive way.
The physical and chemical board with solid core and epoxy resin is better. The final application shows that the physical and chemical board is cheap, and the solid core physical and chemical board is more beautiful, which is basically satisfied by the ordinary primary and secondary school laboratories. The resin has better low temperature resistance, and the epoxy resin table is usually used in universities, biochemical laboratories, GMP workshops and other high-end laboratories. It depends on whether you need low temperature or not. If you don't need it, the physical and chemical board is better. Finally, it depends on the cost performance.
Epoxy resin is a kind of inorganic compound with two or more epoxy groups in its molecule. Except in general, their absolute molecular weight is not high. The molecular structure of epoxy resin is characterized by vivid epoxy groups in the molecular chain, which can be located at the end, two ends or ring structure of the molecular chain.
Because of the vivid epoxy groups in the molecular structure, they can react with various curing agents to form insoluble polymers with three-way network structure. All macromolecular compounds containing epoxy group in molecular structure are called epoxy resin. The cured epoxy resin has good physical and chemical functions. It has excellent bonding strength to the surface of metal and non-metallic materials, good dielectric function, small variable expansion rate, good dimensional fluctuation of products, high hardness, good flexibility, and fluctuation to alkali and local solvents Therefore, it is widely used in various departments of national defense and national economy for pouring, impregnating, laminating, adhesive and coating.
The solid core physicochemical board is made by thickening the kraft paper on the part of the core material and pressing it at low temperature and high pressure. The thickness is more than 3 mm. It can be made into table or cabinet board indirectly without adhering to the base material.
