Ko te tikanga, ko te pokey ohydroxypropyl methylcellulosehe teitei ake, engari ka whakawhirinaki ano ki te tohu o te whakakapinga me te tohu toharite o te whakakapinga.Hydroxypropyl methylpūtauhe katote-kore cellulose etera me te ahua o te paura ma, kaore he kakara me te reka, ka whakarewahia i roto i te wai me te nuinga o nga whakarewa pararopi polar me nga waahanga tika o te ewaro/wai, te propanol/wai, te dichloroethane, me etahi atu, kare e rewa i roto i te acetone me te ewaro tino, ka pupuhi ki roto i te colloid marama, paku kapua ranei i roto i te wairewa wai matao.Ko te wairewa wai he mahi mata, ka hanga he kiriata angiangi i muri i te whakamaroketanga, ka puta te huringa whakahuri mai i te sol ki te ra i runga i te raupapatanga i te whakamahana me te whakamatao.He maamaa teitei me te mahi pumau.
Ko te Hydroxypropyl methylcellulose te taonga o te waiariki.I muri i te whakamahana o te wairewa wai o te hua, ka hanga he reera, ka heke, ka memeha i muri i te whakamahana.He rereke te pāmahana gelation o nga whakaritenga rereke.He rereke te wairewa ki te pokey.Ko te iti o te pokey, ka nui ake te whakarewatanga.He rereke nga ahuatanga o te hydroxypropyl methylcellulose me nga whakaritenga rereke.Ko te whakakorenga o te hydroxypropyl methylcellulose i roto i te wai kaore e pa ki te uara pH.
Āhuatanga: Kei a ia nga ahuatanga o te kaha o te matotoru, te tote tote, te pumau o te PH, te pupuri i te wai, te pumau o te rahi, te tino pai o te hanga kiriata, te whānuitanga o te aukati i te whana, te whakamararatanga me te whakakotahitanga.
Ko tepupuri waio nga hua hydroxypropyl methylcellulose e pa ana ki nga mea e whai ake nei:
1. Te riterite o te hydroxypropyl methylcellulose
Ko te hydroxypropyl methylcellulose, te methoxyl me te hydroxypropoxyl te taurite ka tohatohahia, he nui te reiti pupuri wai.
2. Hydroxypropyl methylcellulose waiariki rangi pāmahana
Ko te teitei ake o te wera o te waiariki, ka nui ake te tere o te pupuri wai;Ki te kore, ka iti ake te utu pupuri wai.
3. Viscosity o te hydroxypropyl methylcellulose
Ka piki te pokey o te hydroxypropyl methylcellulose, ka piki ano te reiti pupuri wai;ka tae te pokey ki tetahi taumata, ka ngawari te piki o te reiti pupuri wai.
4. Te nui o te hydroxypropyl methylcellulose kua tapirihia
Ko te nui ake o te hydroxypropyl methylcellulose ka taapirihia, ka nui ake te tere o te pupuri wai me te pai ake o te paanga o te wai.I roto i te awhe o te 0.25-0.6% te taapiri, ka tere te tere o te pupuri i te wai me te pikinga o te moni taapiri;ka piki ake te moni taapiri, ka heke te pikinga o te reiti pupuri wai.
