He pai ake te painga o te hydroxypropyl methylcellulose ki te pupuri wai o te kumete whare

1. Ko te hiahia o te pupuri wai o te hydroxypropyl methylcellulose

Ko te pupuri wai o te kumete e pa ana ki te kaha o te kumete ki te pupuri wai. Ko te kumete me te ngoikore o te pupuri i te wai ka paheke te toto me te wehewehe i te wa e kawe ana me te rokiroki, ara, ka maanu te wai ki runga, ka totohu te onepu me te sima ki raro. Me whakaoho ano i mua i te whakamahi. Ko nga momo turanga katoa e hiahia ana ki te kumete mo te hanga, he momi wai. Mena he kino te pupuri i te wai o te moata, ka ngohia te moata kua oti te whakauru i te wa e pa ana te moata kua oti te whakauru ki te poraka, ki te turanga ranei i te wa e whakamahia ana te moata. I te wa ano, ko te mata o waho o te kumete ka whakaeto i te wai ki roto i te hau, na te iti o te makuku i roto i te kumete na te matewai, e pa ana ki te whakamakuku o te sima, i te wa ano ka pa ki te whanaketanga noa o te kaha moata. , ka puta te kaha, ina koa ko te atanga i waenga i te kumete whakapakeke me te paparanga turanga. ka heke iho, ka pakaru te moata ka taka. Mo te kumete he pai te pupuri i te wai, he tino rawaka te whakamakuku sima, ka taea te whakawhanake i te kaha, ka pai ake te hono ki te paparanga turanga.

2. Nga tikanga pupuri wai tuku iho

Ko te otinga tawhito ko te whakamakuku i te turanga, engari kaore e taea te whakarite kia rite te makuku o te turanga. Ko te whainga pai mo te whakamakuku o te kumete ciment i runga i te turanga ko: ka uru te hua o te hydration ciment ki roto i te turanga me te tukanga o te turanga o te wai mimiti, te hanga i te "hononga matua" whai hua ki te turanga, kia tutuki ai te kaha here e hiahiatia ana. Ko te whakamakuku tika i runga i te mata o te turanga ka nui te mararatanga i roto i te whakauru wai o te turanga na te rerekee o te pāmahana, te wa whakamakuku, me te riterite o te whakamakuku. He iti ake te whakauru wai o te turanga, ka mau tonu te wai i roto i te kumete. I mua i te puta o te whakamakuku ciment, ka uru te wai, e pa ana ki te whakauru o te waiu ciment me nga hua o te wai ki roto i te matrix; he nui te wai o te turanga, ka rere te wai i roto i te kumete ki te turanga. He puhoi te tere o te hekenga o te reo, a ka hangaia he paparanga wai-wai i waenga i te kumete me te matrix, e pa ana ki te kaha here. Na reira, te whakamahi i te tikanga whakamakuku turanga noa e kore anake e taka ki te whakaoti tika i te raruraru o te nui absorption wai o te turanga taiepa, engari ka pā te kaha hononga i waenganui i te kumete me te turanga, hua i roto i te hollowing me te kapiti.

3. Ko te mahi a te hydroxypropyl methylcellulose ki te pupuri wai

Ko te mahi pupuri wai o te hydroxypropyl methylcellulose he maha nga painga:

(1). Ko te pai o te mahi pupuri wai ka tuwhera te kumete mo te wa roa, a he pai nga painga o te hanga rohe-nui, te roa o te mahi i roto i te paera, me te whakakotahi i te puranga me te whakamahi puranga.

(2). Ko te pai o te pupuri i te wai ka tino whakamakuku te ciment i roto i te kumete, ka pai ake te pai o te mahi honohono o te moata.

(3). He pai te mahi pupuri wai o te kumete, na reira ka iti ake te moata ki te wehewehe me te whakaheke toto, me te pai ake o te mahi me te hanga o te moata.
