ʻO HydroxyPropsl Methylcelllolose (HPMC) he hui nui i hoʻohana nuiʻia ma nāʻano hana likeʻole ma muli o keʻano likeʻole o kaʻoihana
1.
A. ʻO Cellulous Backbone:
ʻO HPMC kahi Derivase Derivative,ʻo ia ka mea i loaʻa mai i ka cellulouse, he polysacractide kūlohelohe i loaʻa i nā paia lāʻau. ʻO ka cellulouse no ka hana houʻana i nā'āpana o β-d-gl-glucoe e hoʻopiliʻia e β (1 → 4) mau paʻa.
b. Koho:
I HPMC,ʻo ka hydroxyl (-oh) i ke poʻo o ke poʻo o ka cellbone i hoʻohuliʻia me nā hui merdroxyproopyl a me nā hui hydroxyproopyl. Ua loaʻa kēiaʻano e pili ana ma o kahi hopena ethifification. ʻO ke kiʻekiʻe o ka hoʻololiʻana (DS) e pili ana i ka helu maʻamau o nā hui hydroxyl hui i kohoʻia ma ke poʻo glucose i loko o ke kaula gluucose ma ke kaula bellouse. ʻO nā ds o ka methyl a me nā hui hydroxyprostl heʻokoʻaʻokoʻa, e pili ana i ka hana o HPMC.
2, synthesis:
A. ʻO Othertification:
Hoʻomoʻaʻiaʻo HPMC ma o keʻano o ka maʻi o ka cellouse me PSplouse ʻO ke kaʻina hana e pili ana i ka hanaʻana i nā cellulouse me ka prostlene oxdene e hoʻolauna ai i nā hui hydroxyprooppyl a laila me ka chlorl chlordide e hoʻolauna ai i nā hui mityl.
b. KA MEA O KA OIHANA NUI:
Hiki ke kāohiʻia nā DS o HPMC ma o ka hoʻoponoponoʻana i nā kūlana e like me ka mahana e like me ka mahana, ka manawa hoʻomaha.
3. Hana:
A. ALOHA:
Hoʻokomoʻiaʻo HPMC i ka wai a me kekahi mau mea hoʻokele organik, e like me ka methanol a me ka ethanol. Eia naʻe, e ho'ēmi ana kona wahi e hoʻonui ai me ka hoʻonuiʻana i ke kaumaha molecular a me ke kiʻekiʻe o keʻano.
b. Nā kumuhana kiʻi:
Hoʻokumuʻo HPMC i kahi kiʻi transparent, hoʻololi i ke kiʻi i ka wā i hoʻopauʻia i ka wai. ʻO kēia mau kiʻiʻoniʻoni he ikaika maikaʻi a me nā waiwai o nā barries.
C. Viscosity:
Hōʻikeʻo HPMC i ka hana Pseuddletic ʻO ka mākaʻikaʻi o nā hoʻoponopono o HPMC e pili ana i nā mea e like me keʻano o ka noʻonoʻo, molela paona, a me ke kiʻekiʻe o keʻano.
d. KAHAKAU AKU:
ʻO kekahi o nā waiwai nui o HPMC kona hiki ke mālama i ka wai. He mea koʻikoʻi kēia waiwai i nā noi likeʻole e like me nā mea kūkulu kūkuluʻana, kahi i hoʻohanaʻiaʻo HPMC e like me ka mea a me ka wai.
e. HANES:
Hoʻohana pinepineʻiaʻo HPMC ma keʻano he mauʻoihana ma nāʻoihana'ē aʻe ma muli o kona hiki ke hana i nā mea ikaika ikaika.
4. Noi:
A. ʻOihana lāʻau lapaʻau:
I nā lāʻau lapaʻau, ua hoʻohanaʻiaʻo HPMC e like me kahi mea paʻa, kiʻiʻoniʻoni
b. Hana Hana:
Ua hoʻohuiʻiaʻo HPMC i nā mokulele e pili ana i nā wahi e pili ana i nā mea kanu gypsum-gypsum e pili ana i nā mea hana e hoʻomaikaʻi ai i ka hana hana
C. Kaʻai meaʻai:
I kaʻoihana meaʻai, hoʻohanaʻiaʻo HPMC e like me kahi shaickener, stabilizer a me Emulsifier i nā huahana e like me nā meaʻala a me nā mea inu a me nā meaʻala.
d. Nā huahana mālama pilikino:
Hoʻohanaʻiaʻo HPMC e like me kahi shaickener, emulsifier a me nā kiʻi kiʻi kiʻi kiʻi a me nā kiʻi paʻi kiʻi ma nā shampos
e. Nāʻeha a me nā kapa komo:
I nāʻeha a me nā lole, ua hoʻohanaʻiaʻo HPMC e hoʻomaikaʻi i ka pākuhi pigment, ciscosity contection a me ka wai.
ʻO ka hydroxyproopylgalylgullose (HPMC) kahi hui Vertitarile me ka nui o nā noi e pili ana i nāʻoihana likeʻole. Kona mau mea hoʻohui pilikino,ʻo synthesis a me nā waiwai e hana ai he hale nui i nā hale kūʻai, nā hale hana pono, nā huahana pilikino a me nā pena. Hoʻomaopopo i nā waiwai o HPMC i nā noi i hanaʻia no nā papa hana likeʻole, e hāʻawi ana i kona hoʻohanaʻana i nā kaʻina hana hou.
