Ko te uara pH whanui o nga hua gypsum he waikawa, he koretake ranei. Inaianei e rua nga momo waahanga hangahydroxypropyl methylcellulosei runga i te maakete: te puhoi me te cellulose inamata (S). Ko te cellulose inamata kaore e pai mo nga punaha gypsum. Ko nga hua, he tino rawakore te wairewa i raro i nga tikanga waikawa, koretake ranei, a ka taea te rewa te hydroxypropyl methylcellulose puhoi ki roto i nga hua gypsum, engari he ngoikoretanga nui te cellulose puhoi, he ngawari ki te whakahiato (ka gypsum I muri i te whakakorikoria o te kumete ki runga i te pakitara mo te wa poto, ka puta mai he waahi iti ki te mata). I tenei wa, i roto i nga hua gypsum, ina koa i roto i te moata gypsum kua rehu-miihini, e hiahiatia ana kia tino marara te cellulose ether me te rewa i roto i te wa poto rawa, e hiahia ana tatou ki te whakahaere rangahau hohonu mo te puhoi-whakarewa cellulose ether tukanga whakaputa. Te maimoatanga o te mata (ehara i te mea e kiia ana ko te taapiri o etahi atu taapiri i roto i te reanga cellulose ether noa), kia uru ai ki te punaha moata gypsum. Ko te Hydroxypropyl methylcellulose ether me te maimoatanga o te mata hohonu ka taea te wa whakangao me nga taonga miihini pai i roto i te kumete gypsum, a ka taea te whakapai ake i te whakahoatanga me te whakaotinga o te moata.
I te nuinga o te waa ka whakamahia e te miihini gypsum moata he iti te pokey hydroxypropyl methylcellulose ether i waenga i te 20,000 me te 75,000, me te nui o te taapiri he 0.2% ki te 0.4%. Ko te wa whakatuu o te moata gypsum rehu-miihini ka whakahaeretia mo te 1 haora. Ka whakamahia e matou te ahotea o te moata gypsum, te kirikiri kirihou, te thixotropy, te rheology me te rite o te slurry ki te whakawa i te mahi o nga hua moata gypsum.
Ka whakaarohia e matou te mana kounga o te desulfurization gypsum source calcining process, fillers (ciment, aggregate fine, heavy calcium powder) me te urunga (ka taea te whakamahi i roto i te disperse latex powder, hydroxypropyl methyl cellulose ether, extended perlite, gypsum retarder) Ko te whiriwhiri o te tauira hua katoa he utu utu.
Hydroxypropyl methyl cellulose ethermo te moata gypsum he tino ma me te pai o te mahi, a kua whakanuia e nga kaihoko moata gypsum.
