ʻO ka hydroxypropyl methylcellulose papa kemika o kēlā me kēia lā!

ʻO ka Hydroxypropyl methyl cellulose (HPMC) kahi polymer non-ionic, kahi ether cellulose non-ionic i hana ʻia mai ka cellulose mea polymer kūlohelohe. ʻAʻohe ʻala o ka huahana, ʻono ʻole, pauka keʻokeʻo ʻaʻohe ʻawahia, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu e hana i kahi hopena viscous moakaka, me ka mānoanoa, ka hoʻopili ʻana, ka hoʻopuehu ʻana, ka emulsifying, ka hana ʻoniʻoni, ka hoʻokuʻu ʻana, ka adsorbing, ka gelling, ka hana ʻili, nā hiʻohiʻona e like me ka paʻa ʻana o ka makū a me nā colloids pale.

Hoʻohana nui ʻia ka HPMC koke i nā kemika lole, nā huahana hoʻomaʻemaʻe kemika o kēlā me kēia lā, nā mea hoʻonani a me nā ʻoihana ʻē aʻe; e like me ka shampoo, ka holoi kino, ka mea hoʻomaʻemaʻe maka, ka lotion, ka kirīmi, ka gel, ka toner, ka mea hoʻomaʻemaʻe lauoho, nā huahana kaila, ka toothpaste, ka luʻu, ka wai pehu mea pāʻani, a pēlā aku.

ʻO nā ʻano huahana o ka hydroxypropyl methyl cellulose papa kemika o kēlā me kēia lā e komo pū me:

1. Nā mea maka kūlohelohe, hoʻonāukiuki haʻahaʻa, hana akahai, palekana a me ka palekana o ke kaiapuni;

2. Ka hoʻoheheʻe ʻana i ka wai a me ka mānoanoa: hiki ke hoʻoheheʻe koke ʻia i ka wai anuanu, hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik a me ka hui ʻana o ka wai a me nā mea hoʻoheheʻe organik;

3. Mānoanoa a me ka hoʻonui ʻana i ka viscosity: ʻo ka hoʻonui iki ʻana o ka hoʻoheheʻe ʻana e hana i kahi hopena viscous maopopo, transparency kiʻekiʻe, hana paʻa, hoʻololi ka solubility me ka viscosity, ʻo ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility; hoʻomaikaʻi maikaʻi i ke kūpaʻa o ke kahe o ka ʻōnaehana;

4. Ke kū'ē'ē pa'akai: He polymer non-ionic ka HPMC, pa'a loa i nā hopena wai o nā pa'akai metala a i'ole nā ​​electrolytes organik;

5. Hana ʻili: loaʻa i ka hopena wai o ka huahana ka hana ʻili, a loaʻa iā ia nā hana a me nā waiwai o ka emulsification, colloid pale a me ke kūpaʻa pili; ʻo ke kaumaha ʻili: 2% ka hopena wai he 42-56dyn/cm;

6. Paʻa PH: paʻa ka mānoanoa o ka hopena wai i loko o ka pae o PH3.0-11.0;

7. Ka hopena paʻa wai: hiki ke hoʻohui ʻia ka waiwai hydrophilic o HPMC i nā huahana slurry, paste a me nā pasty e mālama i ka hopena paʻa wai kiʻekiʻe;

8. Gelation wela: Ke hoʻomehana ʻia ka hopena wai i kahi mahana, lilo ia i opaque a hiki i ka wā e hana ai i kahi kūlana flocculation (poly), kahi e nalowale ai ka viscosity o ka hopena. Akā ma hope o ka hoʻomaʻalili ʻana, e hoʻololi hou ia i ke kūlana hopena mua. ʻO ka mahana e hana ʻia ai ka hanana gel e pili ana i ke ʻano o ka huahana, ka nui o ka hopena a me ka wikiwiki o ka hoʻomehana ʻana;

9. Nā ʻano ʻē aʻe: nā waiwai hana kiʻiʻoniʻoni maikaʻi loa, a me kahi ākea o ke kū'ē ʻana i ka enzyme, ka hoʻokahe ʻana a me ke kūpaʻa ʻana, a pēlā aku.
