Pehea ka nui o kāu ʻike e pili ana i ka Hydroxypropyl methyl cellulose?

ʻO ka Hydroxypropyl methylcellulose (HPMC) he cellulose ether i loaʻa mai ka cellulose maoli.He polymer synthetic, wai-soluble, non-ionic i hoʻohana mau ʻia i nā ʻoihana like ʻole e like me ke kūkulu ʻana, nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani, a me nā textiles.

Hana ʻia ka HPMC ma o ka hoʻololi ʻana i ka cellulose me ka propylene oxide a me ka methyl chloride e hoʻokomo i nā pūʻulu hydroxypropyl a me methyl i loko o ka mole cellulose.ʻO ke degere o ka hoʻololi ʻana (DS) o HPMC e pili ana i ka helu o ka hydroxypropyl a me nā pūʻulu methyl ma kēlā me kēia anhydroglucose unit (AGU) o cellulose.

Loaʻa iā HPMC kekahi mau waiwai e hoʻohana pono ai i nā noi like ʻole.Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hana i kahi hopena maʻemaʻe, a maikaʻi ke kūpaʻa wela.Paʻa nō hoʻi ia ma lalo o nā kūlana maʻamau o ka mahana a me ka pH a ʻaʻole hiki ke decompose maʻalahi.He hygroscopic ka HPMC, ʻo ia hoʻi, hiki iā ia ke komo a mālama i ka makū.ʻAʻole ia he mea ʻawaʻawa, ʻaʻole hoʻonāukiuki, a ʻaʻole allergenic, kahi e palekana ai no ka hoʻohana ʻana i nā noi he nui.

I ka ʻoihana kūkulu, hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa, mea hoʻopaʻa, a me ka mea mālama wai i nā huahana sima, nā mea hoʻopili tile, nā plasters, a me nā mea hale ʻē aʻe.I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ʻo HPMC ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka kiʻiʻoniʻoni-mua i loko o ka papa a me nā ʻano capsule.I ka ʻoihana meaʻai, hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa, emulsifier, a me ka stabilizer i nā huahana like ʻole.I loko o nā mea hoʻonaninani, hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa, film-former, a me ka emulsifier i loko o nā creams, lotions, a me nā mea hana ʻē aʻe.

Ma keʻano holoʻokoʻa, he polymer maʻalahi a pono hoʻi ʻo HPMC i loaʻa ka nui o nā noi i nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa.
