Hoʻohana ʻia i kēlā me kēia lā ʻo Hydroxypropyl Methyl Cellulose (HPMC) i ka holoi ʻana

ʻO kēlā me kēia lā kemika hydroxypropyl methylcellulose he polymer synthetic i hana ʻia mai ka cellulose kūlohelohe ma o ka hoʻololi kemika. ʻO ka cellulose ether kahi hua o 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 ke hana me nā mea hana 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 200,000 viscosity instant hydroxypropyl methylcellulose no ka papa kemika i kēlā me kēia lā he pauka keʻokeʻo a melemele iki paha, ʻaʻohe, ʻono ʻole a ʻona ʻole. Hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka mea hoʻoheheʻe hui ʻia o ka mea organik e hana i kahi hopena viscous akaka. Loaʻa i ka wai wai ka hana o ka ʻili, ke aniani kiʻekiʻe, ke 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 kumu, hiki i ka hoʻohana ʻana i ka cellulose (antifreeze thickener) i ka shampoo a me ka gel wai hiki ke hōʻemi nui i ke kumukūʻai a hoʻokō i ka hopena i makemake ʻia.

Nā hiʻohiʻona a me nā pono o kēlā me kēia lā kemika 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.

ʻO ka laulā o ka hoʻohana ʻana i kēlā me kēia lā kemika cellulose HPMC:

Hoʻohana ʻia i ka shampoo, ka holoi kino, ka hoʻomaʻemaʻe maka, ka lotion, ka ʻaila, ka gel, ka toner, ka lauoho lauoho, nā huahana styling, toothpaste, saliva, ka wai pāʻani pāʻani.

ʻO ka hana o kēlā me kēia lā kemika cellulose HPMC

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 methylcellulose kūpono no ka ʻoihana kemika i kēlā me kēia lā he 100,000, 150,000, a me 200,000. E like me kāu kumu hoʻohālikelike, ʻo ka nui o ka hoʻohui i ka huahana maʻamau 3 a 5/1000
