ʻO kēlā me kēia lā kemika hydroxypropyl methylcellulose kahi polymer synthetic i hana ʻia mai nā linters pulupulu cellulose maoli ma o ka hoʻololi ʻana i ka etherification.ʻO ka cellulose ether kahi mea i loaʻa i ka cellulose maoli.ʻOkoʻa ka hana ʻana o ka cellulose ether mai nā polymers synthetic.ʻO kāna mea kumu nui he cellulose, kahi hui polymer maoli.Ma muli o ke ʻano o ke ʻano o ka cellulose kūlohelohe, ʻaʻohe hiki i ka cellulose pono ke hana me nā mea etherification.Eia naʻe, ma hope o ka hoʻomaʻamaʻa ʻana i ka mea hoʻohuhū, ua luku ʻia nā paʻa 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 i kēlā me kēia lā he pauka keʻokeʻo a melemele iki paha, a ʻaʻohe ona, ʻono ʻole a ʻona ʻole.He mea hoʻoheheʻe hiki ke hoʻopuehu koke ʻia i loko o ka wai anuanu a hui pū ʻia me ka mea olaola, a hiki i ke kūpaʻa kiʻekiʻe i loko o kekahi mau minuke e hana i kahi hopena viscous akaka.Loaʻa i ka wai wai ka hana ma luna, ke aniani kiʻekiʻe, kūpaʻa ikaika, a ʻaʻole pili i ka pH ke hoʻoheheʻe ʻia i ka wai.Loaʻa iā ia ka mānoanoa a me nā hopena antifreeze i nā shampoos a me nā gel wai, a he paʻa ka wai a me nā waiwai hana kiʻiʻoniʻoni maikaʻi no ka lauoho a me ka ʻili.Me ka piʻi nui ʻana o nā kumu kumu, cellulose (antifreeze thickener) i hoʻohana ʻia i ka mea holoi holoi lole, shampoo, gel wai hiki ke hōʻemi nui i ke kumukūʻai a hoʻokō i ka hopena i makemake ʻia.
ʻO nā hiʻohiʻona a me nā pono o kēlā me kēia lā kemika wai anuanu cellulose HPMC:
1. ʻO ka huhū haʻahaʻa, ka wela kiʻekiʻe a me ka meaʻawaʻawaʻole;
2. Paʻa ka waiwai pH ākea, hiki ke hōʻoia i kona kūpaʻa ma ka laulā o ka waiwai pH 3-11;
3. Hoʻonui i ka hoʻomaʻamaʻa;
4. E hoʻonui i ka ʻūhā, hoʻopaʻa i ka ʻūhā, hoʻomaikaʻi i ka manaʻo o ka ʻili;
5. Hoʻomaikaʻi maikaʻi i ka wai o ka ʻōnaehana.
6. E hoʻohana maʻalahi, e hoʻokomo i loko o ka wai anuanu e hoʻopuehu koke me ka ʻole o ka clumping
ʻO ka laulā o ka hoʻohana ʻana i kēlā me kēia lā kemika cellulose HPMC:
Hoʻohana ʻia i loko o ka mea holoi lole, shampoo, holoi kino, hoʻomaʻemaʻe maka, ʻaila, ʻaila, gel, toner, conditioner, huahana styling, toothpaste, mouthwash, toy bubble water.
ʻO ka hana o ka cellulose cellulose HPMC i kēlā me kēia lā:
I nā noi cosmetic, hoʻohana nui ʻia ia no ka mānoanoa, foaming, stable emulsification, dispersion, adhesion, hoʻomaikaʻi ʻana i ka hana kiʻiʻoniʻoni a me nā waiwai paʻa wai o nā mea hoʻonaninani, hoʻohana ʻia nā huahana kiʻekiʻe-viscosity no ka mānoanoa, hoʻohana nui ʻia nā huahana haʻahaʻa-viscosity no ka hoʻokuʻu. ka hoʻopuehu a me ka hana kiʻiʻoniʻoni.
ʻO ka ʻenehana HPMC cellulose i kēlā me kēia lā:
ʻO ka viscosity o ka hydroxypropyl methyl fiber kūpono no ka ʻoihana kemika i kēlā me kēia lā he 100,000, 150,000, a me 200,000.ʻO ka maʻamau, hoʻohana nui ʻia ka viscosity kiʻekiʻe, a ʻo ka hopena mānoanoa ka mea maikaʻi loa.E like me kāu hoʻohālikelike ponoʻī, ʻo ka nui o ka hoʻohui i ka huahana he 1,000 maʻamau.2 ʻāpana i 4 ʻāpana no ke tausani.
Hoʻomalu
Hōʻike ka hydroxypropyl methylcellulose i kēlā me kēia lā kemika kemika ʻaʻole i kūpono i ka ʻike maikaʻi ʻole, ka hopena mānoanoa maikaʻi ʻole, ka lahilahi ma hope o ka mālama ʻana i ka wā lōʻihi, a lilo paha kekahi mau ʻāpana.I mea e pale aku ai i ka ua o ka cellulose i ka wā o ka hoʻohana ʻana, pono e hoʻoulu ʻia ma mua o ka piʻi ʻana o ke kūlike.hoʻohana.
