ʻO wai ka mea hana hypromellose?

Hāʻawi ʻo Kima Chemical i kahi ākea o nā huahana hypromellose e hoʻokō i nā pono o nā noi like ʻole. Loaʻa nā huahana hypromellose o ka ʻoihana i nā māka viscosity like ʻole a me nā degere o ka hoʻololi ʻana (DS), a me nā ʻano hoʻohālikelike e hoʻokō i nā koi o ka mea kūʻai aku.

Hana ʻia nā huahana hypromellose a Kima Chemical me ka hoʻohana ʻana i ka ʻenehana hana kiʻekiʻe a me nā ana hoʻomalu maikaʻi koʻikoʻi e hōʻoia i ka maikaʻi a me ka hana. Hoʻopili pū ʻia nā huahana hypromellose o ka hui me nā kūlana honua like ʻole, me USP, EP, JP, a me FCC.

ʻO Hypromellose kahi polymer versatile i hoʻohana ʻia i nā ʻano ʻoihana ākea. ʻO Kima Chemical kahi mea hana nui o hypromellose, e hāʻawi ana i kahi ākea o nā māka a me nā kikoʻī e hoʻokō i nā pono o nā noi like ʻole. Hana ʻia nā huahana hypromellose a Kima Chemical me ka hoʻohana ʻana i ka ʻenehana hana kiʻekiʻe a me nā ana hoʻomalu maikaʻi koʻikoʻi e hōʻoia i ka maikaʻi a me ka hana. Me kona mau waiwai maikaʻi a me ka laulā o nā noi, hypromellose kahi mea waiwai nui i nā huahana a me nā ʻoihana.

ʻO Hypromellose, ka mea i kapa ʻia ʻo hydroxypropyl methylcellulose (HPMC), he polymer semi-synthetic i hoʻohana ʻia i nā ʻano ʻoihana ākea. Hana ʻia ia ma ke kemika hoʻololi ʻana i ka cellulose, kahi polymer maoli i loaʻa i nā mea kanu. Hoʻohana mau ʻia ʻo Hypromellose ma ke ʻano he mānoanoa, emulsifier, a me ka stabilizer i ka ʻoihana meaʻai, a ma ke ʻano he binder, film-former, a me ka lubricant i ka ʻoihana lāʻau. ʻO Kima Chemical kahi mea hana nui o hypromellose, e hāʻawi ana i kahi ākea o nā māka a me nā kikoʻī e hoʻokō i nā pono o nā noi like ʻole.

ʻO ke kinona o Hypromellose

Hypromellosehe polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose. Hana ʻia ia ma ka hana ʻana i ka cellulose me ka propylene oxide a me ka methyl chloride. ʻO ka polymer ka hopena i loaʻa i ke kaumaha molecular o 10,000 a 1,000,000 Daltons, e pili ana i ke degere o ka hoʻololi ʻana (DS) a me ka pae viscosity.

ʻO ka hana kemika o hypromellose he iwi kuamoʻo cellulose me nā hui hydroxypropyl a me methyl i hoʻopili ʻia i nā ʻāpana anhydroglucose. ʻO ka degere o ka hoʻololi ʻana (DS) e pili ana i ka helu awelika o nā pūʻulu hydroxypropyl a me methyl i kēlā me kēia ʻāpana anhydroglucose. Hiki i ka DS ke hele mai ka 0.1 a i ka 2.5, e pili ana i nā waiwai i makemake ʻia o ka hypromellose.

Nā waiwai o Hypromellose

ʻO ka Hypromellose ka pauka keʻokeʻo a keʻokeʻo ʻole a ʻono ʻole. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe organik he nui, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe nonpolar. ʻO ka Hypromellose kahi viscosity kiʻekiʻe ma nā haʻahaʻa haʻahaʻa, e lilo ia i mea mānoanoa a me ka mea hoʻopili. Loaʻa iā ia nā waiwai hana kiʻiʻoniʻoni maikaʻi loa, i mea e pono ai i ka hana ʻana i nā uhi a me nā kiʻiʻoniʻoni.

ʻO nā waiwai o hypromellose e hilinaʻi ʻia ma ke ʻano o ka hoʻololi ʻana (DS) a me ka pae viscosity. ʻOi aku ka nui o ka hoʻoheheʻe wai a me nā haʻahaʻa haʻahaʻa haʻahaʻa i nā māka DS kiʻekiʻe, ʻoiai ʻo nā māka DS haʻahaʻa he kiʻekiʻe ka wela gelation a ʻoi aku ka maikaʻi o ka wela. Hoʻoholo ka māka viscosity i ka mānoanoa o ka solution hypromellose a me kona hiki ke hana i nā gels.

Nā noi o Hypromellose

Hoʻohana ʻia ʻo Hypromellose i nā ʻano ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me ke kūkulu ʻana. I ka ʻoihana meaʻai, hoʻohana ʻia ka hypromellose ma ke ʻano he mānoanoa, emulsifier, a me ka stabilizer i nā ʻano huahana like ʻole, me ka ice cream, sauces, a me nā meaʻai i kālua ʻia. I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ka hypromellose ma ke ʻano he mea hoʻopaʻa, film-former, a me ka lubricant i nā papa, nā capsules, a me nā ʻaila. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻopili i nā ʻano hoʻokuʻu hoʻokuʻu ʻia.

I loko o ka ʻoihana hoʻonaninani, hoʻohana ʻia ka hypromellose ma ke ʻano he mānoanoa, emulsifier, a me ke kiʻiʻoniʻoni-mua i loko o nā lotions, creams, a me nā huahana makeup. I ka ʻoihana kūkulu hale, hoʻohana ʻia ka hypromellose ma ke ʻano he mānoanoa a me ka hoʻopaʻa ʻana i nā huahana sima, e like me nā morta a me nā grouts.
