Commodity: Synthetic Cryolite Formula: Na3AlF6 M.W.: 209.95 Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Ethanol alcohol distillation column 1. It is standard 95-96% alcohol equipment. Also it can distill pure water. 2.The distillation system has  three columns  and  continuous  distillation  process.The process is the  same as industrial(large scale) alcohol equipment.  Mash distillation  column distills  fermented  mash or light alcohol  to 50% alcohol ethanol . It has red copper bubble cap trays, standard design. It auto continuously feeds material liquid, auto continuously produces 50% alcohol ethanol and auto continuously discharges waste,  ethanol discharge in waste 0.05%, better than international standard requirements. The first rectification distillation  column  increases  alcohol degree  to 70-75% ,  separates  fusel oil and high boiling point  Impurities.  It auto discharges waste water,  ethanol discharge in waste 0.05%, better than international standard requirements. The second rectification distillation  column  increases alcohol degree to 95%,  separates low boiling point  impurities  like acetaldehyde and methanol . 3.  The rectification system uses  industrial(large scale) standard process, but the whole set alcohol equipments are installed in one frame, like integration  module, even  you can run it by a button.
Metal tin is mainly used in the manufacture of alloys. Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment. Tin's modern application is as a solder for the electronics industry. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.
