ʻO ka Hydroxypropyl methyl cellulose (HPMC) he polymer non-ionic, he cellulose ether non-ionic i hana ʻia mai ka cellulose material polymer maoli. ʻO ka huahana he ʻala ʻole, ʻono ʻole, pauka keʻokeʻo non-toxic, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu e hana i kahi hopena viscous akaka, me ka mānoanoa, hoʻopaʻa ʻana, hoʻopuehu, emulsifying, hana kiʻiʻoniʻoni, hoʻopaneʻe, adsorbing, gelling, hana ʻili, nā hiʻohiʻona like e like me ka mālama ʻana i ka wai a me nā colloids pale.
Hoʻohana nui ʻia ka HPMC i nā kemika textile, nā huahana hoʻomaʻemaʻe i kēlā me kēia lā, nā mea hoʻonaninani a me nā māla ʻē aʻe; e like me ka shampoo, ka holoi kino, ka hoʻomaʻemaʻe maka, ka lotion, ka ʻaila, ka gel, ka toner, ka lauoho lauoho, nā huahana styling, toothpaste, Saliva, toy bubble water, etc.
ʻO nā hiʻohiʻona huahana o kēlā me kēia lā kemika hydroxypropyl methyl cellulose ka mea nui:
1. Nā mea kūlohelohe maoli, haʻahaʻa haʻahaʻa, haʻahaʻa hana, palekana a me ka palekana o ke kaiapuni;
2. ʻO ka wai-solubility a me ka mānoanoa: hiki ke hoʻoheheʻe ʻia i ka wai anuanu koke, hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe a me ka hui ʻana o ka wai a me nā mea hoʻoheheʻe organik;
3. ʻO ka mānoanoa a me ka viscosity-hoʻonui: ʻo ka hoʻonui liʻiliʻi o ka hoʻoheheʻe ʻana e hana i kahi hopena viscous māmā, ʻike kiʻekiʻe, hana paʻa, hoʻololi i ka solubility me ka viscosity, ʻoi aku ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility; hoʻomaikaʻi maikaʻi i ka paʻa kahe o ka ʻōnaehana;
4. Paʻakai paʻakai: HPMC he non-ionic polymer, paʻa paʻa i loko o ka wai o nā paʻakai metala a i ʻole nā electrolytes organik;
5. Ka hana o ka ʻili: ʻo ka hoʻonā wai o ka huahana he hana ili, a aia nā hana a me nā waiwai o ka emulsification, colloid pale a me ka paʻa pili; ʻO ka haʻahaʻa o ka ʻili: 2% ka hopena wai he 42-56dyn/cm;
6. Paʻa PH: paʻa ka viscosity o ka wai i loko o ka laulā o PH3.0-11.0;
7. Ka hopena mālama wai: hiki ke hoʻohui ʻia ka waiwai hydrophilic o HPMC i ka slurry, paste a me nā huahana pasty e mālama i ka hopena paʻa wai kiʻekiʻe;
8. Thermal gelation: Ke hoʻomehana ʻia ka wai wai i kekahi mahana, lilo ia i opaque a hiki i ka hoʻokumu ʻana i kahi kūlana flocculation (poly), e lilo ai ka hopena i kona viscosity. Akā ma hope o ka hoʻoluʻu ʻana, e huli hou ia i ke kūlana hoʻonā kumu. ʻO ka mahana i loaʻa ai ka hanana gel e pili ana i ke ʻano o ka huahana, ka neʻe ʻana o ka hoʻonā a me ka helu wela;
9. Nā hiʻohiʻona ʻē aʻe: nā waiwai hana kiʻiʻoniʻoni maikaʻi loa, a me kahi ākea o ke kūpaʻa enzyme, dispersibility a me ka cohesiveness, etc.
