1、Caco3 calcium carbonate

White solid,tasteless and odorless，Relative density 2.71. 825 ~ 896.6 ℃ decomposition,at about 825 ℃ is decomposed into calcium oxide and carbon dioxide. Melting point 1339 ℃,melting point is 1289 ℃ under 10.7 MPa.

Chemical properties

classfiction：Calcium carbonate is divided into heavy calcium carbonate,light calcium carbonate,colloidal calcium carbonate and crystalline calcium carbonate.

 What's it made of：The glass is a finished product manufactured by crushing,grading and separating white stones containing above 90% CaCO powder with ramon mill or other high-pressure mill.

Health hazards：The worker that is engaged in exploitation processing often appears inflammation of upper respiratory tract,bronchitis,can have emphysema

 

Colorless,transparent,odorless,viscous liquid,sweet taste,with hygroscopic

Chemical properties: esterification with acid,as with the esterification of phthalic acid to produce alkyd resin. Transesterification occurs with esters. React with hydrogen chloride to form chlorohydrin

Non-toxic. Even if the total amount of dilute solution drink up to 100g is harmless,in the body after hydrolysis oxidation and become a source of nutrition. In animal experiments,alcohol has the same narcotic effect as alcohol when drunk in very large quantities.

  Xanthan gum for light yellow to white can flow powder,slightly smelly. Soluble in cold and hot water,neutral solution,resistant to freezing and thawing,insoluble in ethanol. 

Where it is from？

  Water dispersion,emulsification into a stable hydrophilic viscous colloid

B. oleracea isolated from the U.S. department of agriculture's institute of northern piorill,Illinois,in 1952,and converted b. oleracea extracts into water-soluble acidic exopolysaccharides.
