kemika hpmc hydroxypropyl methyl cellulose i hoʻohana ʻia i ke kūkulu ʻana CAS 9004-65-3
Hydroxypropyl methyl cellulose (HPMC)
ʻAno: Milky keʻokeʻo a i ʻole ka pauka keʻokeʻo
Ka wela o ka carbonization: 280-300 %
Ka wela kala: 190-200 %
ʻOi aku ka nui o ka nui: 100 mesh pass rate ʻoi aku ka nui ma mua o 98.8%; 80 mesh pass rate 99.9%; ʻO ka nui o ka nui o nā kikoʻī kūikawā he 40-60 mesh
ʻIke ʻia: 0.25-0.70g/cm(maʻamau e pili ana i 0.5g/cm), kikoʻī gravity: 1.26-1.31
Solubility: hiki ke hoʻoheheʻe ʻia i loko o ka wai a me kekahi mau mea hoʻoheheʻe, e like me ke ʻano kūpono o ka ethanol / wai, propanol / wai. ʻO ka hoʻonā wai i loaʻa i ka hana ma luna, ke aniani kiʻekiʻe a me ka hana paʻa.
ʻO Hydroxypropyl methyl cellulose, i ʻike ʻia ʻo hydroxypropyl methyl cellulose, fiber bundle hydroxypropyl methyl ether, ʻo ia ke koho ʻana o ka pulupulu maʻemaʻe maʻemaʻe ma ke ʻano he mea maka ma lalo o nā kūlana alkaline e ka kūikawā.
etherification a me ka hoʻomākaukau ʻana. Loaʻa iā ia nā hiʻohiʻona o ka hiki ke mānoanoa, ka paʻakai paʻakai, ka haʻahaʻa o ka lehu, ka paʻa PH, ka paʻa ʻana o ka wai, ke kūpaʻa dimensional, ka hana kiʻiʻoniʻoni maikaʻi loa, a me ke kūpaʻa ʻana o ka mildew,
dispersibility a me ka pili.
ʻOihana kūkulu hale
1. ʻO ka pahu sima
2.Ceramic tile cement
3.Asbestos a me nā mea pale refractory ʻē aʻe: ma ke ʻano he mea hoʻokuʻu, hoʻomaikaʻi i ka fluidity, akā hoʻomaikaʻi hoʻi i ka adhesion o ka substrate.
4.Gypsum coagulant slurry: hoʻomaikaʻi i ka mālama ʻana i ka wai a me ka hana, hoʻomaikaʻi i ka pili ʻana i ka substrate
5.Joint sima: hoʻohui ʻia i ka lepo lepo no ka papa gypsum e hoʻomaikaʻi ai i ka wai a me ka paʻa ʻana o ka wai.
