ʻO ka Zinc Stearate me Cas 557-05-1
He pauka keʻokeʻo māmā maikaʻi ka zinc stearate. ʻO ke ʻano molekala ZN (C17H35COO) 2, ʻano molekala RCOOZnOOCR (ʻo R ka hui alkyl i hui ʻia i loko o ka waikawa stearic ʻoihana), hiki ke puhi ʻia, ke kaumaha kikoʻī 1.095, kiko hoʻā ahi ponoʻī 900 ℃, ka nui 1.095, kiko heheʻe 130 ℃, momona. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, ka ethanol a me ka ether, akā hiki ke hoʻoheheʻe ʻia i loko o ka ethanol wela, ka turpentine, ka benzene a me nā mea hoʻoheheʻe organik a me nā waikawa. Hoʻomehana ʻia a hoʻoheheʻe ʻia ka zinc stearate i loko o kahi mea hoʻoheheʻe organik, a laila hoʻomaʻalili ʻia e hana i kahi mea colloidal, kahi e hoʻoheheʻe ʻia i loko o ka waikawa stearic a me ka paʻakai zinc e pili ana i ka wā e hālāwai ai me ka waikawa ikaika. He lubricating, hygroscopic, ʻaʻohe ʻawaʻawa, hoʻonāukiuki iki, ʻaʻohe haumia, a ʻaʻohe mea weliweli. Hiki ke hoʻokaʻawale ʻia ka zinc stearate a me ka calcium stearate ma o ka waiwai e hiki ke hoʻoheheʻe ʻia ka zinc stearate i loko o ka benzene a ʻaʻole hiki ke hoʻoheheʻe ʻia ka calcium stearate i loko o ka benzene.

1. Hoʻohana ʻia e like me ka lubricant palupalu no nā huahana laholio a me ka mea hoʻopili no nā lole
2. Hoʻohana ʻia e like me ka mea hoʻopaʻa o nā huahana plastik PVC a me ka mea palupalu o nā huahana laholio
3. Hoʻohana ʻia i ka ʻoihana lāʻau lapaʻau, ka hoʻomākaukau ʻana i ka ʻaila hoʻōla a me ka lubricant, a hoʻohana ʻia hoʻi ma ke ʻano he mea hoʻomaloʻo pena. Hoʻohana ʻia no ka hana ʻana i nā huahana PVC ʻona ʻole a me nā huahana laholio. Hiki iā ia ke hoʻomaikaʻi pono i ke kūpaʻa photothermal o PVC a me nā huahana laholio me ka hopena synergistic o ka calcium stearate a me ka barium stearate; Hoʻohana ʻia no nā huahana laholio, a me PP, PE, PS, EPS polymerization additives a me ka hana penikala.
4. Mea hoʻopaʻa; lubricant; grease; Accelerator; Mea hoʻomānoanoa
5. Hoʻohana ʻia ia i loko o ka polyethylene, polystyrene, PVC a me ka mea hoʻolaha kemika kiʻekiʻe a me ka mea hoʻopaʻa wela i ka ʻoihana petrochemical. Hoʻohana ʻia no ka masterbatch kala (particle) ma ke ʻano he mea hoʻopaʻa wela, dispersant a me ka lubricant.
ʻEke 25kgs a i ʻole ke koi a nā mea kūʻai aku. E mālama iā ia mai ka mālamalama ma kahi mahana ma lalo o 25 ℃.
