Zinc Stearate Ndi Cas 557-05-1
Zinc stearate ndi ufa woyera wopepuka. Fomula ya molekyulu ZN (C17H35COO) 2, kapangidwe ka molekyulu RCOOZnOOCR (R ndi gulu losakanikirana la alkyl mu asidi ya stearic ya mafakitale), yoyaka, yokoka 1.095, malo oziyatsira 900 ℃, kuchuluka kwa 1.095, malo osungunuka 130 ℃, mafuta. Sisungunuka m'madzi, ethanol ndi ether, koma imasungunuka mu ethanol yotentha, turpentine, benzene ndi zinthu zina zachilengedwe ndi ma acid. Zinc stearate imatenthedwa ndikusungunuka mu organic solvent, kenako imazizira kuti ipange chinthu cha colloidal, chomwe chimasungunuka kukhala stearic acid ndi mchere wofanana wa zinc ikakumana ndi asidi wamphamvu. Ndi mafuta, hygroscopic, si poizoni, imakwiyitsa pang'ono, yopanda kuipitsa, komanso si yoopsa. Zinc stearate ndi calcium stearate zitha kulekanitsidwa ndi momwe zinc stearate imasungunuka mu benzene ndipo calcium stearate sisungunuka mu benzene.

1. Amagwiritsidwa ntchito ngati mafuta ofewetsa zinthu za mphira ndi chotsukira nsalu
2. Imagwiritsidwa ntchito ngati chokhazikika cha zinthu zapulasitiki za PVC ndi chofewetsa zinthu za rabara
3. Imagwiritsidwa ntchito mumakampani opanga mankhwala, kukonza mafuta ophikira ndi mafuta odzola, komanso imagwiritsidwa ntchito ngati choumitsira utoto. Imagwiritsidwa ntchito pokonza zinthu za PVC ndi rabara zomwe si poizoni. Imatha kusintha bwino kukhazikika kwa kutentha kwa PVC ndi rabara pogwiritsa ntchito mphamvu ya calcium stearate ndi barium stearate; Imagwiritsidwa ntchito pazinthu za rabara, komanso zowonjezera za PP, PE, PS, EPS polymerization ndi kupanga mapensulo.
4. Chokhazikika; mafuta odzola; mafuta owonjezera mphamvu; Cholimbikitsira; Wothira mafuta
5. Imagwiritsidwa ntchito mu polyethylene, polystyrene, PVC ndi mankhwala apamwamba kwambiri ogawa ulusi wa mankhwala komanso chokhazikika pa kutentha mumakampani opanga mafuta. Imagwiritsidwa ntchito ngati masterbatch (tinthu tating'onoting'ono) ngati chokhazikika pa kutentha, chosungunula ndi chopaka mafuta.
Chikwama cha 25kgs kapena zosowa za makasitomala. Chisungeni kutali ndi kuwala pa kutentha kosakwana 25℃.
