Ko te kaha o te pupuri wai o te hydroxypropyl methylcellulose kei runga i te ihirangi hydroxypropyl. I raro i nga ahuatanga kotahi, ko te kaha o te pupuri wai o te hydroxypropyl teitei he kaha ake, a ko te ihirangi metotypropy te whakaheke tika i nga tuhinga hydroxypropyl. . Ko te teitei o te kiko o te hydroxypropyl methylcellose, na te mea ka kowhiri i tetahi hua, me whiriwhiri e koe te hua e rite ana ki a koe kia rite ki te kaupapa o te hua.
Te pāmahana me ētahi atu āhuatanga e whai hua ana ki te pupuri i te wai o te hydroxypropyl methylcellolose.
Te pāmahana waiariki:
Ko te HPMC Cellulose Ether he tino nui o te wai whakatipu wai me te pupuri i te wai pai; Engari tera, kua mau tonu te pupuri i te wai.
Te tirohanga o te HPMC Cellulose:
A, no te piki haere o te HPMC, ka piki ake tona pupuri i te wai; Ka nui haere te aro whakarereketanga ki tetahi whānuitanga, ko te pikinga o te wai pupuri wai.
Cellulose Ether HPMCOus:
He tauhohenga a HPMC, he tohatoha taapiri mo te methoxyl me te hydroxypropoxyl, he pai te pupuri i te wai.
Te inenga HPMC Ether:
Ko te nui ake o te horopeta, ko te teitei ake o te utu o te reti wai me te tino kitea o te painga o te wai.
I te wa e 0.25 ~ 0.6%, ka piki haere te tere o te pupuri wai me te pikinga o te rahinga taapiri; Ka piki ake te taapiri o te taapiri, ko te pikinga o te huringa o te reanga o te wai ka heke iho.
Hei poto, ko te pupuri i te HPMC wai e pa ana ki nga mea penei i te pāmahana me te tirohanga, me tana reti wai e pa ana ki te nui o te hydroxypropyl atylcroplose. A, no te nui o te methylcropyl methylcellulose tae atu ki tetahi uara, ka tae tana mahi pupuri wai ki te pupuri i te wai.
