Zinc Stearate Nrog Cas 557-05-1
Zinc stearate yog lub teeb dawb zoo hmoov.Molecular formula ZN (C17H35COO) 2, molecular qauv RCOOZnOOCR (R yog cov sib xyaw alkyl pawg nyob rau hauv industrial stearic acid), combustible, tshwj xeeb gravity 1.095, tus kheej ignition point 900 ℃, ceev 1.095, melting point 130 greasy.,Nws yog insoluble hauv dej, ethanol thiab ether, tab sis soluble hauv kub ethanol, turpentine, benzene thiab lwm yam organic solvents thiab acids.Zinc stearate yog rhuab thiab yaj hauv cov kuab tshuaj organic, thiab tom qab ntawd txias los tsim cov tshuaj colloidal, uas yog decomposed rau hauv stearic acid thiab sib xws zinc ntsev thaum ntsib cov kua qaub.Nws yog lubricating, hygroscopic, non-toxic, me ntsis irritating, tsis muaj kuab paug, thiab tsis muaj teeb meem.Zinc stearate thiab calcium stearate tuaj yeem sib cais los ntawm cov cuab yeej uas zinc stearate yog soluble hauv benzene thiab calcium stearate yog insoluble hauv benzene.
