Te pānga me te mātāpono o te pupuri wai o te Hpmc Hydroxypropyl methylcellulose

I roto i te moata sima me te paru gypsum, ko te mahi matua a te HPMC he pupuri wai me te whakamātotoru. Ka taea e ia te whakapai ake i te kaha here me te ārai i te pituitary o te paru.

Ka pā te pāmahana hau, te pāmahana hau me te tere o te pēhanga hau ki te tere mimiti o te wai i roto i te moata sima me ngā hua kei roto i te gypsum.

I ngā wā rerekē, he rerekētanga ētahi o ngā pānga pupuri wai o te HPMC. I roto i ngā hanganga motuhake, ka taea te whakarite i te pānga pupuri wai o te paru mā te whakanui ake, te whakaiti rānei i te nui o te HPMC i tāpirihia. Ko te pupuri wai o te methyl cellulose ether i raro i ngā āhuatanga pāmahana teitei he tohu nui hei wehewehe i te kounga o te methyl cellulose ether. Ka taea e ngā hua raupapa HPMC pai rawa atu te whakaoti rapanga o te pupuri wai i raro i te pāmahana teitei.

I te wā wera nui, inā koa i ngā wāhi wera me te maroke, me te hanganga paparanga angiangi i te taha paki. E hiahiatia ana te HPMC kounga teitei hei whakapai ake i te pupuri wai o te paru. Ka taea e ia te whakapai ake i te kaha o te ngota hāora i runga i te rōpū hydroxyl ki te hanga hononga hauwai me te hononga ether. Ka hanga te wai kore utu hei wai here, kia pai ai te whakahaere i te mimiti o te wai i puta mai i te pāmahana teitei o te rangi. He taumata pupuri wai teitei.

Ka taea te whakamarara ōrite me te whai hua i te HPMC cellulose kounga teitei ki roto i te moata sima me ngā hua e hangai ana ki te gypsum. Ā, ka takai i ngā matūriki totoka katoa hei hanga i tētahi kiriata mākū. Ka tukuna mārire te makuku i roto i te paparanga turanga mō te wā roa, ā, ka pāngia te rauemi whakapūkara kore-waro e te tauhohenga wai. Mā reira ka whakarite i te kaha here me te kaha pēhi o te rauemi. Nō reira, me hanga i te raumati pāmahana teitei kia tutuki ai te pānga pupuri wai. Kia tino tāpirihia ngā hua HPMC kounga teitei kia rite ki te tauira, ki te kore ka puta he raruraru kounga pēnei i te kore e ranea te wai. Engari ka whakapiki ake i te uauatanga o te hanga o ngā kaimahi. I te hekenga o te pāmahana, ka taea te whakaiti mārire i te nui o te HPMC, ā, ka taea hoki te whakatutuki i te pānga pupuri wai.
