ʻO ka hydroxypropyl methylcellulose papa kemika o kēlā me kēia lā he polymer synthetic i hana ʻia mai nā linters pulupulu cellulose kūlohelohe ma o ka hoʻololi ʻana o ka etherification. ʻO ka Cellulose ether kahi derivative o ka cellulose kūlohelohe. He ʻokoʻa ka hana ʻana o ka cellulose ether mai nā polymers synthetic. ʻO kāna mea kumu nui loa he cellulose, kahi hui polymer kūlohelohe. Ma muli o ke ʻano kūikawā o ke ʻano cellulose kūlohelohe, ʻaʻohe hiki o ka cellulose ponoʻī ke hana me nā mea etherification. Eia naʻe, ma hope o ka mālama ʻana i ka mea pehu, ua luku ʻia nā pilina hydrogen ikaika ma waena o nā kaulahao molekala a me nā kaulahao, a lilo ka hoʻokuʻu ikaika o ka hui hydroxyl i cellulose alkali reactive. E kiʻi i ka cellulose ether.
ʻO ka hydroxypropyl methylcellulose papa kemika o kēlā me kēia lā he pauka keʻokeʻo a melemele iki paha, a he ʻala ʻole, ʻono ʻole a ʻaʻohe mea ʻawahia. He mea hoʻoheheʻe hiki ke hoʻopuehu koke ʻia i ka wai anuanu a hui pū ʻia me nā mea organik, a hiki i ke kūlike kiʻekiʻe loa i loko o kekahi mau minuke e hana i kahi hopena viscous moakaka. Loaʻa i ka wai wai ka hana ʻili, ke aniani kiʻekiʻe, ke kūpaʻa ikaika, a ʻaʻole i hoʻopilikia ʻia e ka pH ke hoʻoheheʻe ʻia i ka wai. Loaʻa iā ia nā hopena mānoanoa a me nā hopena antifreeze i nā shampoos a me nā gels ʻauʻau, a he paʻa wai a me nā waiwai hana kiʻiʻoniʻoni maikaʻi no ka lauoho a me ka ʻili. Me ka piʻi koke ʻana o nā mea maka kumu, hiki i ka cellulose (antifreeze thickener) i hoʻohana ʻia i ka detergent holoi lole, shampoo, shower gel ke hōʻemi nui i ke kumukūʻai a hoʻokō i ka hopena i makemake ʻia.
Nā hiʻohiʻona a me nā pono o ka wai anuanu o kēlā me kēia lā cellulose HPMC:
1. Hoʻonāukiuki haʻahaʻa, wela kiʻekiʻe a ʻaʻohe ʻawahia;
2. ʻO ke kūpaʻa o ka waiwai pH ākea, hiki ke hōʻoia i kona kūpaʻa ma ka laulā o ka waiwai pH 3-11;
3. Hoʻonui i ke kūlana;
4. Hoʻonui i ka huʻa, hoʻopaʻa i ka huʻa, hoʻomaikaʻi i ka ʻili;
5. Hoʻomaikaʻi pono i ka wai o ka ʻōnaehana.
6. Maʻalahi e hoʻohana, e hoʻokomo i loko o ka wai anuanu e hoʻopuehu koke me ka ʻole o ka puʻupuʻu
ʻO ka laulā o ka noi o ka cellulose papa kemika i kēlā me kēia lā HPMC:
Hoʻohana ʻia i loko o ka mea holoi lole, shampoo, holoi kino, mea hoʻomaʻemaʻe maka, lotion, kirīmi, gel, toner, conditioner, nā huahana kaila, toothpaste, mouthwash, mea pāʻani pehu wai.
Ke kuleana o ka cellulose papa kemika o kēlā me kēia lā HPMC:
I nā noi hoʻonaninani, hoʻohana nui ʻia no ka hoʻomānoanoa, ka hoʻopuehu ʻana, ka emulsification paʻa, ka hoʻopuehu ʻana, ka hoʻopili ʻana, ka hoʻomaikaʻi ʻana i ka hoʻokumu ʻana i nā kiʻiʻoniʻoni a me nā waiwai paʻa wai o nā mea hoʻonaninani, hoʻohana ʻia nā huahana viscosity kiʻekiʻe no ka hoʻomānoanoa ʻana, hoʻohana nui ʻia nā huahana viscosity haʻahaʻa no ka hoʻopuehu ʻana i ka hoʻokuʻu ʻana a me ka hoʻokumu ʻana i nā kiʻiʻoniʻoni.
ʻO ka ʻenehana cellulose HPMC papa kemika i kēlā me kēia lā:
ʻO ka mānoanoa o ka fiber hydroxypropyl methyl i kūpono no ka ʻoihana kemika o kēlā me kēia lā he 100,000, 150,000, a me 200,000. Ma keʻano laulā, hoʻohana nui ʻia ka mānoanoa kiʻekiʻe, a ʻo ka hopena mānoanoa ka mea maikaʻi loa. Wahi a kāu ʻano hana ponoʻī, ʻo ka nui o ka hoʻohui ʻana i ka huahana he 1,000. 2 ʻāpana a 4 ʻāpana no hoʻokahi tausani.
Nā Mālama
ʻO ka hydroxypropyl methylcellulose papa kemika i kēlā me kēia lā i kūpono ʻole ʻia e hōʻike ana i ka moakaka maikaʻi ʻole, ka hopena mānoanoa maikaʻi ʻole, ka lahilahi ma hope o ka mālama ʻana i ka wā lōʻihi, a hiki i kekahi mau ʻāpana ke lilo i ʻōpala. I mea e pale aku ai i ka ua ʻana o ka cellulose i ka wā e hoʻohana ai, pono e hoʻoulu ʻia ma mua o ka piʻi ʻana o ke ʻano. hoʻohana.
