The lab bench in the laboratory furniture is the most easily broken by the researchers, because what experimental reactions will be carried out on the bench, so the material of the bench is very critical. At present, the experimental bench materials on the market mainly include epoxy resin plates, ceramic plates, stainless steel plates, and solid core physiochemical plates. Among them, the “fight” is more epoxy plates and ceramic plates. Here we distinguish the two materials. Parameters, you will know which is the "king".
1. Temperature resistance: The temperature resistance of ceramic countertops is about 600 degrees, and the temperature resistance of epoxy resin is about 150 degrees. This is related to their processing technology. The temperature is too high and the epoxy board is easily broken due to heat. , whitening, foaming, emitting harmful gases;
2, mechanical strength: epoxy resin countertops from the epoxy resin and silica powder re-mixed with adhesives and colorants cast at about 100 degrees in the shape of the laboratory bench, its compactness and pressed into the open The physiochemical board is not as good as it is, and the ceramic table made by firing is much different. Therefore, the epoxy resin countertop is prone to scratches during use. Ceramic countertops are fired, and the countertops and sides have a layer of dense and hard special professional glazes. Professional ceramic countertops with a professional thickness of more than 20mm cannot be traced on the metal cutting tools. Therefore, its mechanical strength is unmatched by other countertops. Once installed, its service life is extremely long;
3, chemical properties: ceramic table in addition to hydrofluoric acid, the other acid and alkali can not have a hazard. The epoxy resin also has its own strong corrosion resistance. Because epoxy resin is cast, its compactness is not high. So there will be a lot of capillary holes on the table, when there is liquid splashed on the table will be partially penetrated into the table. No matter how you wipe it, you still cannot clean it completely. Although the main component of the countertop, epoxy resin, will not be corroded, the pigments inside will be corroded by acids and alkalis. Spots and spots will appear on the countertops. This situation will basically occur in about 1 year, causing the table top to be unsightly.
Whether this is an analysis or not, the “struggle” within the laboratory furniture members is not very clear.
