ʻO ka Hydroxypropyl methyl cellulose (HPMC) kahi ʻano cellulose i hui pū ʻia me nā ʻano like ʻole e hoʻonui wikiwiki ʻia ana ka hopena, ka dosage a me ka maikaʻi i nā makahiki i hala.Non-ionic cellulose i hui ʻia eter i hana ʻia e nā kaʻina hana ʻē aʻe.
He maikaʻi ka hoʻopuehu ʻana, emulsifying, mānoanoa, cohesive, mālama wai a me nā waiwai paʻa i ka HPMC.Hiki ke hoʻoheheʻe ʻia i ka wai, a hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka acetone ma lalo o 70%.Hiki ke hoʻoheheʻe ʻia ʻo HPMC me kahi hoʻolālā kūikawā i ka ethanol.Hiki ke hoʻohana nui ʻia ka HPMC e like me ka uhi kiʻiʻoniʻoni, ka mea hoʻokuʻu hoʻomau a me ka mea hoʻopaʻa no ka hoʻomākaukau ʻana i ka lāʻau lapaʻau, a hiki ke hoʻohana nui ʻia i nā petrochemicals, nā mea kūkulu hale, nā ceramics, textiles, meaʻai, nā mea kanu i kēlā me kēia lā ma o ka hoʻohana ʻana i kona mānoanoa, dispersing, emulsifying a me ka hana kiʻiʻoniʻoni. waiwai., resin synthetic, lāʻau lapaʻau, pena a me nā mea uila a me nā māla ʻē aʻe.
Hiki ke hoʻokaʻawale ʻia ke kaʻina hana o HPMC i ʻelua mau ʻāpana: ke ʻano o ke kaʻina hana a me ke ʻano hana wai.I kēia manawa, hoʻohana nā ʻāina hoʻomohala e like me ʻEulopa, ʻAmelika Hui Pū ʻIa a me Iapana i ke kaʻina hana gas-phase, me ka hoʻohana ʻana i ka pulp lāʻau ma ke ʻano he mea maka (ua hoʻohana ʻia ka pulupulu pulu e hana i nā huahana kiʻekiʻe-viscosity), lawe ʻia ka alkalization a me ka etherification i ka hopena like. nā mea hana, a ʻo ka hopena nui he hopena pae.Loaʻa i ka ipu hao kahi pahu hoʻoulu ʻana i waena a me kahi pahi lele lele ʻaoʻao i hoʻolālā kūikawā ʻia no ka hana ʻana i ka cellulose ether, hiki ke loaʻa kahi hopena hui maikaʻi.
Ua ʻōlelo nā mea loiloi ʻoihana mai Xinsijie me ka ulu mau ʻana o ka hoʻokele waiwai a me ka hoʻomaikaʻi mau ʻana i ka maikaʻi o ke ola o ka poʻe, ua hoʻomau ka koi no ka hydroxypropyl methylcellulose i ka mākeke Kina.No ka manawa lōʻihi, ʻoi aku ka nui o ka noi o ka mākeke hydroxypropyl methylcellulose o koʻu ʻāina i ka hana a me nā uhi.Me ka hoʻomau mau ʻana o nā ʻoihana i lalo, ua hoʻomaka ka nui o ka noi no ka hydroxypropyl methylcellulose i ka meaʻai a me ka lāʻau lapaʻau.I ka wā e hiki mai ana, ʻo ke kūkulu ʻana, nā meaʻai a me nā ʻoihana lāʻau lapaʻau e lilo i mea ikaika nui no ka ulu ʻana o ka mākeke hydroxypropyl methylcellulose o koʻu ʻāina.
