Introduction to common materials of acid alkali resistant and corrosion-resistant table in laboratory

Source: unknown popularity: Time of publication: 14:56, August 27, 2020
In Chemistry laboratory In the experimental projects, acids, bases and organic solvents are often used.
Therefore, it is generally required that The experimental station The surface material shall be corrosion resistant. In addition, for some high temperature chemical experiments, the surface of the laboratory should be resistant to high temperature.


 
1. Ceramic table surface: ceramic table panel has the advantages of high temperature resistance, corrosion resistance, high insulation and high wear resistance, but the disadvantages are that it is not resistant to impact and relatively low voltage resistance.
High surface finish. It is suitable for some high temperature experiments and some chemical experiments. Of course, if you don't use hydrofluoric acid on the surface of the experiment bench.

 
2. Surface of marble table: the surface of marble table has the advantages of high temperature resistance, and can withstand the temperature above 1000 ℃.
In addition, the marble table surface has high hardness, not easy to deform, good wear resistance and good load-bearing performance, but its cost is relatively high, so it is usually used for the surface of laboratory scale bench and high-temperature bench.

 
3. Solid core physical and chemical board: solid core physical and chemical board is a kind of board made of synthetic resin impregnated with wood fiber, which can withstand high temperature and high pressure. The surface is treated by special physical and chemical treatment.
It has the advantages of low cost, acid and alkali corrosion resistance, heat resistance, wear resistance and impact resistance. Most of the experiments in the general chemistry laboratory platform choose the solid core physical and chemical board as the surface of the laboratory bench.
However, it should be noted that the physical and chemical board cores are heat resistant, but not high temperature resistant, and can not withstand temperatures above 80 ℃ for a long time.

 
4. Epoxy resin board: it is said that the real core physical and chemical board is the common surface of many common chemical laboratories, but if Laboratory furniture To be more durable, epoxy board is a good choice.
The epoxy resin board is mainly composed of reinforced epoxy resin, the internal and external materials are the same, and the repairability is strong. It has strong acid and alkali resistance, impact resistance and high temperature resistance.
