5 Notes edit most manufacturers of carbon molecular sieve zeolite Shanghai is not much difference in appearance, so users rely on observation of molecular sieve is difficult to distinguish in the end is the appearance of imported or domestically produced zeolite molecular sieves. But there is little, if at the time of purchase of equipment, the manufacturers claim that using high-quality imported zeolite, but the price is far below the market price, then Shanghai 3a molecular sieve, then beware. Buy sell fine, equipment manufacturers are unlikely to sell equipment at a loss. Buy domestically built equipment is not terrible Shanghai zeolite molecular sieves companies, but it took the price of imported zeolite molecular sieve has bought domestically, that a big loser. Molecular sieve is a cubic lattice of an aluminosilicate compound having, composed mainly of aluminosilicates connection open framework structure through an oxygen bridge, there are a lot of uniform pore size and neat in pore structure, large surface area of ??the inner hole. It also contains a low price and a larger ionic radius of metal ions and the chemical form of water. As the water molecules in the continuous heating lost, but the crystal skeleton structure constant, the formation of many of the same size of the cavity, the cavity there are many of the same diameter of pores connected to Shanghai _ new molecular sieve zeolite 4a (certified) _ Shanghai by Shanghai new zeolite molecular sieves Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is Shanghai's Songjiang District, elemental leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. There are new leaders in the molecular sieve with the staff warmly welcome all inquiries negotiations to create new molecular sieve a better future.
