He aha ka Hydroxypropyl methylcellulose?

1. Hoʻolauna

ʻO ka Hydroxypropyl methylcellulose (HPMC) he polymer hiki ke hoʻohana nui ʻia i ka wai i loaʻa mai ka cellulose.He pauka non-ionic, ʻala ʻole, ʻono ʻole, keʻokeʻo a keʻokeʻo keʻokeʻo i hoʻohana nui ʻia i ka ʻoihana meaʻai, lāʻau lapaʻau, a me nā ʻoihana hoʻonaninani.Loaʻa i ka HPMC ka laulā o nā noi, me ka mānoanoa, emulsifying, suspending, stabilizing, a me ka hana kiʻiʻoniʻoni.Hoʻohana ʻia ia ma ke ʻano he binder, lubricant, a disintegrant i ka hana ʻana i nā papa a me nā capsules.

2. Mea Maka

ʻO ka mea maka nui i hoʻohana ʻia no ka hana ʻana i ka HPMC he cellulose, he polysaccharide i haku ʻia me nā ʻāpana glucose.Hiki ke loaʻa ka cellulose mai nā kumu like ʻole, me ka pulp lāʻau, ka pulupulu, a me nā mea kanu ʻē aʻe.A laila mālama ʻia ka cellulose me kahi kaʻina kemika e hana i ka hydroxypropyl methylcellulose.

3. Hana Hana

ʻO ke kaʻina hana o HPMC e pili ana i kekahi mau ʻanuʻu.ʻO ka mea mua, mālama ʻia ka cellulose me kahi alkali, e like me ka sodium hydroxide, e hana i kahi cellulose alkali.Hoʻopili ʻia kēia cellulose alkali me ka methyl chloride a me ka propylene oxide e hana i ka hydroxypropyl methylcellulose.Hoʻomaʻemaʻe ʻia a hoʻomaloʻo ʻia ka hydroxypropyl methylcellulose e lilo i pauka keʻokeʻo.

4. Mana Mana

He ʻāpana koʻikoʻi ka mana maikaʻi o ka hana hana o HPMC.Hoʻoholo ʻia ka maikaʻi o ka huahana e ka maʻemaʻe o ka cellulose, ke kiʻekiʻe o ka hoʻololi ʻana o ka hui hydroxypropyl, a me ke ʻano o ka hoʻololi ʻana o ka hui methyl.Hoʻoholo ʻia ka maʻemaʻe o ka cellulose ma ka hoʻāʻo ʻana i ka viscosity o ka hopena, aʻo ke degere o ka hoʻololi ʻana e hoʻoholo ʻia ma ka hoʻāʻo ʻana i ke degere o ka hydrolysis o ka hydroxypropyl methylcellulose.

5. Packaging

Hoʻokomo pinepine ʻia ʻo HPMC i loko o nā ʻeke a pahu paha.Hana ʻia nā ʻeke i ka polyethylene a i ʻole polypropylene, aʻo nā pahu i hana ʻia i ke kila a i ʻole ka plastic.Pono e koho ʻia ka mea hoʻopili e hōʻoia i ka pale ʻana o ka huahana mai ka makū a me nā mea ʻē aʻe.

6. Waihona

Pono e mālama ʻia ka HPMC ma kahi maloʻo a maloʻo, ma kahi mamao o ka lā a me nā kumu wela ʻē aʻe.Pono e pale ʻia ka huahana mai ka makū a me nā mea kūlohelohe ʻē aʻe.

7. Ka hopena

ʻO ka HPMC kahi polymer hiki ke hoʻohana nui ʻia i ka wai i loaʻa mai ka cellulose.Hoʻohana ʻia ia i nā ʻoihana like ʻole, me ka ʻoihana meaʻai, lāʻau lapaʻau, a me nā ʻoihana hoʻonaninani.ʻO ke kaʻina hana o HPMC e pili ana i kekahi mau ʻanuʻu, me ka mālama ʻana i ka cellulose me kahi alkali, ka hopena o ka cellulose alkali me ka methyl chloride a me ka propylene oxide, a me ka hoʻomaʻemaʻe a me ka maloʻo ʻana o ka hydroxypropyl methylcellulose.He ʻāpana koʻikoʻi ka mālama ʻana i ka maikaʻi o ke kaʻina hana, a pono e mālama ʻia ka huahana ma kahi maloʻo a maloʻo, ma kahi mamao o ka lā a me nā kumu wela ʻē aʻe.
