ʻO HPMC, ʻo ka inoa piha ʻo Hydroxypropyl Methylcellulose, he non-ionic cellulose ether i hoʻohana nui ʻia i ke kūkulu ʻana, ka lāʻau lapaʻau, ka meaʻai, nā kemika i kēlā me kēia lā a me nā māla ʻē aʻe.
1. Hoʻokaʻawale ʻia e ka viscosity
ʻO ka viscosity o HPMC kekahi o kāna mau waiwai kino koʻikoʻi, a ʻo ka HPMC me nā viscosities like ʻole he ʻokoʻa koʻikoʻi i ka noi. ʻO ka laulā viscosity mai ka viscosity haʻahaʻa (ʻumi o cps) a hiki i ka viscosity kiʻekiʻe (ʻumi tausani o cps).
HPMC viscosity haʻahaʻa: Hoʻohana maʻamau i nā noi e koi ana i ka hoʻoheheʻe wikiwiki ʻana a i ʻole ka kahe ʻana, e like me ka hoʻokuʻu ʻana i ka lāʻau lapaʻau wai, sprays, etc.
Medium viscosity HPMC: hoʻohana nui ʻia i nā kemika i kēlā me kēia lā, e like me ka shampoo, ka wai ʻauʻau, a me nā mea ʻē aʻe, e hāʻawi ana i ka hopena mānoanoa a me nā waiwai rheological maikaʻi.
ʻO ka HPMC viscosity kiʻekiʻe: hoʻohana nui ʻia i nā mea hana, e like me ka mortar maloʻo, ke kīleʻa seramika, ka putty pā o loko a me waho, a me nā mea ʻē aʻe, e hāʻawi ana i ka mānoanoa maikaʻi loa, paʻa wai a me nā waiwai kūkulu.
2. Hoʻokaʻawale ʻia ma ke degere o ka hoʻololi ʻana
ʻO ke degere o ka hoʻololi ʻana o HPMC e pili ana i ka helu o ka hydroxypropyl a me ka methyl substituents i loko o kāna mole, i hōʻike pinepine ʻia ʻo MS (hydroxypropyl degree of substitution) a me DS (methyl substitution).
Haʻahaʻa haʻahaʻa o ka hoʻololi ʻana i ka HPMC: hoʻoheheʻe koke ʻia a hoʻohana nui ʻia i nā noi e koi ana i ka hoʻoheheʻe wikiwiki ʻana, e like me ka uhi papa lāʻau lapaʻau a me nā mea inu koke.
Kiʻekiʻe kiʻekiʻe o ka hoʻololi HPMC: He kiʻekiʻe viscosity a ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai, a kūpono i nā huahana e koi ana i ka viscosity kiʻekiʻe a me ka paʻa wai kiʻekiʻe, e like me nā mea kūkulu hale a me nā mea hoʻonaninani maikaʻi loa.
3. Hoʻokaʻawale ʻia e nā wahi noi
ʻOkoʻa loa ka hoʻohana pono ʻana o HPMC ma nā ʻāpana like ʻole, a hiki ke hoʻokaʻawale ʻia i loko o kēia mau ʻāpana e like me nā kahua noi:
mea kukulu hale
ʻO ka hana nui o ka HPMC i ke kahua kūkulu ʻo ia ka hoʻomaikaʻi ʻana i ka hana hana a me ka lōʻihi o nā mea, me:
ʻO ka pāpaʻi maloʻo: Hāʻawi ka HPMC i ka mālama wai maikaʻi, ka lubricity a me ka hana, hoʻomaikaʻi i ka hana ʻana a me ka maikaʻi o ka huahana.
Tile adhesive: Hoʻonui i ka ikaika paʻa a me nā waiwai anti-slip e hōʻoia i ka paʻa a me ka lōʻihi o ka paving tile.
Pena a me ka putty: E hoʻonui i ka rheology a me ka paʻa ʻana o ka wai o ka pena a me ka putty e pale aku ai i ka haki ʻana a me ka pauka.
lāʻau lapaʻau
I ka lāʻau lapaʻau, hoʻohana nui ʻia ka HPMC ma ke ʻano he lāʻau lapaʻau, me:
ʻO ka uhi ʻana i ka papa: Ma ke ʻano he mea hoʻopili papa, hāʻawi ia i ka moisture-proof, solubilization a me nā hana hoʻokuʻu hoʻomau e hoʻomaikaʻi i ke kūpaʻa a me ke ʻano o ka lāʻau.
Gel: hoʻohana ʻia e hoʻomākaukau i nā gels pharmaceutical, e hāʻawi ana i ka adhesion maikaʻi a me ka biocompatibility.
meaʻai
Hoʻohana nui ʻia ʻo HPMC e like me ka mānoanoa, emulsifier a me ka stabilizer i ka ʻoihana meaʻai, me:
Nā huahana Noodle: E hoʻonui i ka paʻakikī a me ka elasticity o ka palaoa, hoʻomaikaʻi i ka ʻono a me ke ʻano.
Nā huahana dairy: Ma ke ʻano he emulsifier a me ka stabilizer, pale ia i ka stratification a me ka ua o nā huahana waiū a hoʻomaikaʻi i ka paʻa o ka huahana.
Kemika i kēlā me kēia lā
I nā kemika i kēlā me kēia lā, hoʻohana nui ʻia ʻo HPMC e like me nā mānoanoa a me nā stabilizers, me:
Shampoo a me ka wai ʻauʻau gel: Hāʻawi i ka viscosity haʻahaʻa a me ka rheology e hoʻomaikaʻi i ka ʻike hoʻohana huahana.
Nā huahana mālama ʻili: Ma ke ʻano he mānoanoa a me ka moisturizer, hoʻonui ia i ka hopena moisturizing a me ka ʻike hoʻohana o ka huahana.
4. Nā kumu kūikawā ʻē aʻe
Hiki ke hoʻohana ʻia ka HPMC i kekahi mau kahua kūikawā, e like me ka ʻoihana ʻaila ʻaila, ʻoihana ceramic, ʻoihana pepa, etc.
ʻO ka hana ʻaila: hoʻohana ʻia i ka ʻeli ʻana i nā wai a me nā wai haʻihaʻi e hāʻawi i nā waiwai mānoanoa maikaʻi a me ka hoʻemi ʻana o ka wai.
ʻO ka ʻoihana seramika: hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa a me ka suspending agent e hoʻomaikaʻi i ka kūpaʻa a me ka wai o ka slurry ceramic.
ʻOihana hana pepa: hoʻohana ʻia no ka mālama ʻana i ka pepa e hoʻonui i kona ikaika a me ka pale wai.
Ma ke ʻano he derivative cellulose multifunctional, loaʻa ka HPMC i nā waiwai kino a me nā kemika a me nā manaʻo noi ākea. Loaʻa nā ʻano like ʻole o ka HPMC i kā lākou mau hiʻohiʻona e pili ana i ka viscosity, degere o ka hoʻololi a me ka hoʻohana. Ke koho ʻana i ke ʻano HPMC kūpono e like me nā koi noi kikoʻī hiki ke hoʻomaikaʻi nui i ka hana a me ka maikaʻi o ka huahana. Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻonui ʻana i nā kahua noi, e lilo ka noi o HPMC i mea ākea a hohonu.
