ʻO ka Hydroxypropyl methylcellulose (HPMC) he mea koʻikoʻi ka wai-soluble nonionic cellulose ether me ka mānoanoa maikaʻi, gelling, hoʻopaʻa ʻana, hana kiʻiʻoniʻoni, lubricating, emulsifying a me ka hoʻokuʻu ʻana i nā hana, no laila ua hoʻohana nui ʻia i nā mea kūkulu hale, nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani a me nā māla ʻē aʻe. .
ʻO ka hana mānoanoa o ka hydroxypropyl methylcellulose
ʻO ka hopena mānoanoa o ka HPMC mai kona ʻano molekala. Aia i loko o ke kaulahao mole HPMC nā pūʻulu hydroxyl a me methyl, hiki ke hana i nā paʻa hydrogen me nā molekole wai, a laila e kaohi ai i ka neʻe ʻana ma waena o nā mole wai a hoʻonui i ka viscosity o ka hopena. Ke hoʻoheheʻe ʻia ka HPMC i ka wai, wehe ʻia kona kaulahao mole i loko o ka wai a hui pū me nā molekole wai e hana i kahi ʻōnaehana pūnaewele, a laila e hoʻonui ai i ka viscosity o ka hopena. Hoʻopili pū ʻia ka mānoanoa o ka HPMC e nā mea e like me kona degere o ka hoʻololi ʻana, ke kaumaha molekala a me ka noʻonoʻo.
Hoʻohana i ka hydroxypropyl methylcellulose i nā mea kūkulu hale
I nā mea kūkulu hale, hoʻohana nui ʻia ʻo HPMC i nā huahana e like me ka mortar sima, nā mea gypsum-based a me nā uhi e like me ka mānoanoa a me ka mālama wai. Hiki i kona hopena mānoanoa ke hoʻomaikaʻi i ka hana kūkulu ʻana o ka mea a hoʻonui i kāna hana anti-sagging, no laila e maʻalahi ke kaʻina hana. No ka laʻana, i loko o ka pahu sima, hiki i ka hoʻohui ʻana o HPMC ke hoʻonui i ka viscosity o ka mortar a pale i ka mortar mai ka haʻi ʻana i ka wā i kūkulu ʻia ma luna o ka ʻili kū. Hiki iā ia ke hoʻomaikaʻi i ka paʻa ʻana o ka wai o ka mortar a pale i ka mortar mai ka maloʻo wikiwiki ʻana, a laila e hoʻomaikaʻi ai i ka ikaika a me ka lōʻihi o ka mortar.
Hoʻohana i ka Hydroxypropyl Methylcellulose ma ke kahua lāʻau lapaʻau
I ka lāʻau lapaʻau, hoʻohana nui ʻia ʻo HPMC i nā papa, capsules, gels, hoʻomākaukau ophthalmic a me nā lāʻau lapaʻau ʻē aʻe e like me ka mānoanoa, kiʻiʻoniʻoni mua a me ka hoʻopili. Hiki i kona hopena mānoanoa maikaʻi ke hoʻomaikaʻi i nā waiwai rheological o nā lāʻau lapaʻau a hoʻomaikaʻi i ka kūpaʻa a me ka bioavailability o nā lāʻau lapaʻau. No ka laʻana, i ka hoʻomākaukau ophthalmic, hiki ke hoʻohana ʻia ka HPMC e like me ka lubricant a me ka mānoanoa, a hiki i kona hopena mānoanoa maikaʻi ke hoʻolōʻihi i ka manawa noho o ka lāʻau lapaʻau ma ka ʻili ocular, a laila e hoʻomaikaʻi ai i ka pono o ka lāʻau.
Hoʻohana i ka Hydroxypropyl Methylcellulose i ka meaʻai
I ka ʻoihana meaʻai, hoʻohana pinepine ʻia ka HPMC i nā meaʻai e like me nā huahana dairy, jellies, nā mea inu a me nā huahana bakena e like me ka mānoanoa, emulsifier a me ka stabilizer. Hiki i kona hopena mānoanoa ke hoʻomaikaʻi i ka ʻono a me ke ʻano o ka meaʻai, a hoʻonui i ka viscosity a me ka paʻa o ka meaʻai. No ka laʻana, i nā huahana waiu, hiki i ka HPMC ke hoʻonui i ka viscosity o ka huahana a pale i ka ua o ka whey, a laila e hoʻomaikaʻi ai i ka ʻono a me ke kūpaʻa o ka huahana.
Hoʻohana i ka Hydroxypropyl Methylcellulose i loko o nā mea hoʻonaninani
Ma ke kahua o nā mea hoʻonaninani, hoʻohana nui ʻia ka HPMC i nā huahana e like me nā lotions, creams, shampoos a me nā conditioners e like me ka mānoanoa, emulsifier a me ka stabilizer. Hiki i kona hopena mānoanoa ke hoʻomaikaʻi i ke ʻano a me ka paʻa o nā mea hoʻonaninani, a hoʻomaikaʻi i ka hopena hoʻohana a me ka ʻike mea kūʻai aku o ka huahana. No ka laʻana, i loko o nā lotions a me nā creams, hiki i ka hoʻohui ʻana o HPMC ke hoʻonui i ka viscosity o ka huahana, e maʻalahi i ka hoʻopili ʻana a me ka hoʻomoʻa ʻana, ʻoiai e hoʻomaikaʻi ana i ka hopena moisturizing o ka huahana.
Ua hoʻohana nui ʻia ʻo Hydroxypropyl Methylcellulose i nā mea kūkulu hale, nā lāʻau lapaʻau, nā meaʻai a me nā mea hoʻonaninani ma muli o kāna mau waiwai mānoanoa. ʻO kāna mīkini mānoanoa ka mea nui e hoʻonui i ka viscosity o ka hopena ma o ka hoʻokumu ʻana i nā paʻa hydrogen me nā mole wai, kaohi ʻana i ka neʻe ʻana o nā molekole wai. Loaʻa i nā māla like ʻole nā koi noi no HPMC, akā ʻo kāna hana nui ka hoʻomaikaʻi ʻana i ka viscosity a me ka paʻa o ka huahana. Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomohala mau ʻana o ka ʻenehana noiʻi, e ʻoi aku ka laulā o nā manaʻo noi no HPMC.
