Hydrexypropropsl hydrolcellse (HPMC)ʻo ia ka mea maʻamau maʻamau maʻamau me ka lehulehu o nā noi, he nui i nā mahina o nā hale lapaʻau, nā meaʻai, nā meaʻai. ʻAʻole ia he solivent Ka hopena o ke kaumaha o ka hopohopo i ka helu a me ke kūlana o ka heluʻana o ka myyll a me hydroxyprostl i loko o kānaʻano mollecular.

Loaʻaʻiaʻo HydroxyProplosel Methylcelllouse e Mitylation a me ka hydroxyprocklation o cellulose. ʻO Cellilose ka cellulose kahi polysacarde kūlohelohe kiʻekiʻe-molecacular e noho ana ma nā paia o nā wahi kanu. ʻO keʻano o keʻano o ka HPMC i hoʻokumuʻia i nā'āpana glucose, e pili ana nā molena lōʻihi e pili ana i β-1,4/4,4 glycoidic Ma kēiaʻano molecular, e hoʻololiʻia kekahi mau pūʻulu hydroxyl e ka methyl (-och₃)
Ua hoʻopilikiaʻia ka wahi o ka HPMC e ka hana molecular a maʻamau i nāʻano likeʻole:
ʻO ka hopena wai E pili kokoke ana kona hopena i ka mahana o ka wai a me ke kaumaha molele o HPMC.
Hōʻike kiʻekiʻe: Ma kahiʻike, e hōʻike ana ka hopena o ka HPMC i kahi kiʻekiʻe kiʻekiʻe,ʻoi aku ka nui o ke kaumaha
ʻO ka hoʻokūkūʻo Thermal: HPMC maikaʻi ma kahi o nāʻano o nā wela aʻaʻole maʻalahi ia e hoʻohemo i ke kaʻina hana o ke kaʻina hana.
2. Mālama i ka HPMC
ʻO HPMC kahi mea waiwai wai-wai, akāʻaʻole ia i hoʻokaʻawaleʻia e nā mea āpau. ʻO konaʻano hoʻowahāwahā e pili ana i ka polarity o ka pākuʻi a me ka hoʻopiliʻana ma waena o nā molekula a me nā molmule hpmc.
Wai: hiki ke hoʻopauʻiaʻo HPMC i ka wai. ʻO ka wai ka mea maʻamau maʻamau, a i ka wā o ke kaʻina hana, e hopohopo nei i nā moleclecles®hpmc Ua hoʻopilikiaʻia ke kiʻekiʻe o ka hoʻohemoʻana e like me ke kaumahaʻo molcular o HPMC, ke kiʻekiʻe o ka huiʻana a me ka hydroxyproflation a me ka hydroxyproflation a me hydroxyproflation a me hydroyproflation a me hydroyprofolan, a me keʻano o ka wai. ʻO ka maʻamau maʻamau,ʻo ka maʻalahi o ka HPMC ka mea maikaʻi loa ma kahi kūlana kūpono.
ʻO nā mea hoʻoponopono maikaʻi: Ua kokoke loaʻo HPMC ma ka hapanui o nā mea kūlohelohe a me nā mea e like me nā mea aloha, a me nā hydrocarbons. ʻO kēia no ka meaʻo kānaʻano molecular e loaʻa ai nā hui hydrophilicl hydrophilics ʻOiai he ikaika ikaika ia no ka wai, he hana maikaʻiʻole ia me ka hapanui o nā mea hana kūlohelohe.
ʻO ka wai wela wai wela: I ka wai mahana (maʻamau 40 ° C i ka 70 ° C) E hoʻonui ana ana ke kiʻekiʻe, hoʻonui i ka helu dissolution a me ka hoʻonāʻana, akā ma nā kiʻekiʻe kiʻekiʻe, akā ma keʻano he kiʻekiʻe, ka mea e pili ana i ka viscosaty o ka hopena.
3, noi o HPMC
Ma muli o kāna mau waiʻona maikaʻi, haʻahaʻa haʻahaʻa, a me ka viscosity haʻahaʻa, a hoʻoponoponoʻia,ʻo HPMC i hoʻohana pinepineʻia ma nāʻano likeʻole.
ʻO kaʻoihana lāʻau lapaʻau: I kaʻoihanaʻo Pharmaceutical,ʻo HPMC e hoʻohanaʻia i nā hoʻomākaukauʻana o nā lāʻau, nā mea lawe, nā mea lawe lāʻau. Hiki iā ia ke kōkua i nā lāʻau lapaʻau paʻakikī i ka wai a hoʻoponopono i ka nui o ka hoʻokuʻuʻana i ka lāʻau.
ʻOihana Kūlana: HPMC, me he mea e hoʻohuiʻia ai ka meaʻai I nā huahana i hoʻopaʻaʻia, hiki iā ia ke hoʻomaikaʻi i ka ductility a me ka kūpaʻa o ka palaoa. Ua hoʻohana pinepineʻiaʻo HPMC ma ka hau hau, nā mea inu a me nā meaʻai momona haʻahaʻa.
ʻO kaʻoihana hana: ma kaʻoihana kūkulu, hoʻohana pinepineʻiaʻo HPMC e like me ke kūkuluʻana i ka papa hana kūkulu.
ʻO nā cosmetics: i nā cosmetics, ke hopohopo nei i hoʻohana nuiʻia e like me ka scackerner, a me nā scabilizer, a me nā shampoos, a me nā shampoos
Hpmche wai wai-wai nui a me keʻano consocous cedie e hiki ke hoʻokumu i kahi'ōnaehana collidal transparent i ka wai. ʻAʻole ia he solvent Ua hōʻikeʻia kona wahi kūpono i ka hopena maikaʻi i ka wai, akā insoluble i ka hapanui o nā consvents. ʻO kēia mau hiʻohiʻona o ka HPMC e hoʻohana nuiʻia i nāʻoihana he nui, me nā mea lapaʻau e komo ana, ka meaʻai, a me nā cosmetics.
