Hydroxypropyll methyl cellulose i te raima me te raima i te gypsum

HPMC hydroxypropyll methyl cellulose in ciment delint and slurry i te wai pupuri me te matotoru, te aukati i te aukati me te sag.

Ko te pāmahana o te rangi, te pāmahana me te reanga o te hau ka pa ki te reanga o te waikawa o te wai i roto i te paruru o te raima me nga hua gypsum. Na i roto i nga waa rereke, ko te taapiri i te hydroxypropyl methyl cellulose te nui o te kaupapa pupuri wai hua he rereke. I roto i te hanga raima, ka taea te whakatika i te hua pupuri wai o te slurry ma te piki haere, te whakaheke ranei i te nui o te HPMC. Ko te pupuri i te wai o te methyl cellulose ether i te pāmahana teitei he tohu nui hei wehe i te kounga o te methyl cellulose Ether.

Ka taea e nga hua o te hydroxyproproney hydroxypropyr methylose te whakaoti i te raru o te pupuri wai i raro i te pāmahana tiketike. I roto i te wa o te pāmahana nui, ina koa i nga waahanga wera me te maroke me te hanga apa angiangi i te taha paki, te hiahia mo te HPMC kounga teitei kia pai ake te pupuri wai. Ko te CeldrooxyPy Celluding, ka taea te whakamahi i te hauhā me te wai o te hydroxyl. Hei ūnga, tutuki i te pupuri i te wai nui.

Ko te kounga nui o te hydroxypropyl cellulose ka taea te whakamahi i nga waahanga raima me nga papaa raima katoa, me te whakakaha i te kaha o te wai.

I roto i te hanga, kia tutuki ai te hua o te tiaki wai, me taapiri i te ahua o te mate, me te whakaheke kaha, ka raru ano te raru o te hanga mahi. I te heke o te pāmahana, ka taea te whakaheke i te nui o te HPMC wai, a ka taea te whakatutuki i te mana pupuri wai.
