He aha ka ʻokoʻa o HPMC a me HEC?

ʻO HPMC ka Hydroxypropyl methyl cellulose ether a ʻo HEC ka hydroxyethyl cellulose ether.

Hydroxypropyl methyl cellulose (HPMC) hoʻolauna:

1, ʻoihana hana: e like me ka wai a me ka slurry slurry hoʻopaʻa ʻana i ka wai, hoʻopaneʻe e hana i ka slurry pumping. I ka plastering, gypsum, putty pauka a i ʻole nā ​​​​mea kūkulu hale ʻē aʻe e like me ka hoʻopili, hoʻomaikaʻi i ka daub a hoʻolōʻihi i ka manawa hana. Hoʻohana ʻia no ka hoʻopili ʻana i ka tile ceramic, marble, plastic decor, paste strengthen agent, hiki nō ke hōʻemi i ka dosage cement.HPMCʻO ka hana paʻa ʻana o ka wai e hana i ka slurry ma hope o ka noi ʻana ʻaʻole ma muli o ka maloʻo wikiwiki a pohā, hoʻonui i ka ikaika ma hope o ka paʻakikī.

2, ka hana ʻana i ka keramika: hoʻohana nui ʻia e like me ka mea hoʻopili i ka hana ʻana i nā huahana ceramic.

3, ʻoihana uhi: i loko o ka ʻoihana uhi e like me ka mānoanoa, dispersant a me ka stabilizer, i ka wai a i ʻole nā ​​​​mea hoʻoheheʻe kūlohelohe i ka solubility maikaʻi. E like me ka mea wehe pena.

4, paʻi ʻīnika: i ka ʻoihana inika e like me ka mānoanoa, dispersant a me ka stabilizer, i loko o ka wai a i ʻole nā ​​​​mea hoʻoheheʻe kūlohelohe i ka solubility maikaʻi.

5, plastic: no ka hana ʻana i ka mea hoʻokuʻu, softener, lubricant, etc.

6, PVC: Ka hana ʻana o PVC ma ke ʻano he dispersant, hoʻomākaukau polymerization hoʻokuʻu i nā mea kōkua nui o PVC. 7, ʻO nā mea ʻē aʻe: hoʻohana nui ʻia kēia huahana i ka ʻili, ka ʻoihana huahana pepa, ka mālama ʻana i nā huaʻai a me ka ʻoihana lole.

Hydroxyethyl cellulose (HEC) hoʻolauna:

HEC Hydroxyethyl cellulose, e like me ke ano o ka nonionic surfactant, ma waho o ka mānoanoa, lana, lana, a me ka ho film-hana, hoopuehu, wai, a me ka hoʻolako i ka pale colloid, no hoi i keia mau waiwai:

1, HEC hiki ke hoʻoheheʻe ʻia i loko o ka wai wela a i ʻole ka wai anuanu, wela a paila ʻole ka ua, hana ia i kahi ākea o ka solubility a me nā waiwai viscosity, a me ka gel non thermal;

2, hiki i kona non-ionic ke noho pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants, paʻakai, he mea momona colloidal maikaʻi loa i loaʻa ka kiʻekiʻe o ka hopena electrolyte;

3, ʻelua ʻoi aku ka nui o ka paʻa wai ma mua o ka methyl cellulose, me ka hoʻoponopono kahe maikaʻi, 4, hiki ke hoʻopuehu HEC i hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose dispersion ka mea ʻoi aku ka maikaʻi, akā ʻoi aku ka ikaika o ka pale colloidal.

Hoʻohana: hoʻohana maʻamau e like me ka mea mānoanoa, mea pale pale, adhesive, stabilizer a me nā mea hoʻohui i ka hoʻomākaukau ʻana i ka emulsion, jelly, ʻaila, lotion, ka mea hoʻomaʻemaʻe maka, suppository a me ka papa, hoʻohana ʻia hoʻi e like me ka hydrophilic gel, skeleton material, hoʻomākaukau ʻana i ke ʻano o ka skeleton type hoʻomau. hoʻomākaukau, hiki ke hoʻohana ʻia e like me ka stabilizer i ka meaʻai.
