Kua tino angitu te hanganga mīhini o te moata parai i ngā tau tata nei. Kua whanake hoki te moata parai mai i te whakaranu-ā-roto tuku iho ki te moata ranunga maroke me te moata ranunga mākū. Ko tōna hiranga mahi me tōna pumau ngā mea matua hei whakatairanga i te whanaketanga o te parai mīhini, ā, ka whakamahia te cellulose ether hei moata parai. He mahi nui tā te tāpiri matua. I roto i tēnei whakamātautau, mā te whakarerekē i te matotoru me te pupuri wai o te cellulose ether, me te whakarerekētanga hangai, i rangahauhia ngā pānga o ngā tohu whakamātautau pēnei i te tere pupuri wai, te ngaronga ōritetanga 2h, te wā tuwhera, te ātete totoro, me te rere o te moata parai ki te hanganga mīhini. Hei whakamutunga, i kitea he āhuatanga o te cellulose ether he tere pupuri wai teitei me te āhuatanga takai pai, ā, he tino pai mō te hanganga mīhini o te moata parai, ā, ko ngā tohu katoa o te moata parai e tutuki ana i ngā paerewa ā-motu.
Te tere pupuri wai o te moata parai
Kei te piki haere te auau pupuri wai o te moata parai ina kei waenganui i te 50,000 ki te 100,000 te matotoru o te cellulose ether, ā, he heke iho ina kei waenganui i te 100,000 ki te 200,000, i te mea kua eke te auau pupuri wai o te cellulose ether mō te rehu mīhini ki te neke atu i te 93%. Ko te teitei ake o te auau pupuri wai o te moata, ko te iti ake o te tūponotanga ka toto te moata. I te wā o te whakamātautau rehu me te mīhini rehu moata, i kitea ina he iti iho i te 92% te auau pupuri wai o te cellulose ether, ka ngawari te toto o te moata i muri i te whakatakotoranga mō tētahi wā, ā, i te tīmatanga o te rehu, he tino ngāwari te aukati i te paipa. Nō reira, i te wā e whakarite ana i te moata parai e tika ana mō te hanganga mīhini, me whiriwhiri tātou i te cellulose ether he nui ake te auau pupuri wai.
Te pakaru o te moata 2h
E ai ki ngā whakaritenga o te GB/T25181-2010 "Mota Whakaranu Kua Rite", ko te whakaritenga mō te ngaronga ōritetanga e rua hāora o te mota parai noa he iti iho i te 30%. Ko te matotoru o te 50,000, 100,000, 150,000, me te 200,000 i whakamahia mō ngā whakamātautau ngaronga ōritetanga 2 hāora. Ka kitea i te pikinga ake o te matotoru o te cellulose ether, ka heke haere te uara ngaronga ōritetanga 2 hāora o te mota, e whakaatu ana hoki ko te matotoru o te cellulose ether. Ko te teitei ake o te uara, ko te pai ake o te pumau ōritetanga o te mota, me te pai ake o te mahi ārai-wehewehe o te mota. Heoi, i te wā o te rehu tuturu, i kitea i te wā o te maimoatanga whakataurite i muri mai, nā te mea he nui rawa te matotoru o te cellulose ether, ka nui ake te piripono i waenga i te mota me te koko, kāore e pai mō te hanganga. Nō reira, ki te whakarite kia kore te mota e tau, kia kore hoki e wehe, ko te iti ake o te uara matotoru o te cellulose ether, ko te pai ake.
Ngā hāora whakatuwheratanga o te moata parai
I muri i te rehu o te moata parai ki te pakitara, nā te mimiti wai o te papa pakitara me te mimiti o te makuku i runga i te mata o te moata, ka hanga he kaha motuhake te moata i roto i te wā poto, ka pā ki te hanganga whakataurite i muri mai. I tātarihia te wā totoka. Ko te uara matotoru o te cellulose ether kei roto i te awhe o te 100,000 ki te 200,000, kāore e tino rerekē te wā whakatakoto, ā, he hononga anō hoki ki te tere pupuri wai, arā, ko te teitei ake o te tere pupuri wai, ko te roa ake o te wā whakatakoto o te moata.
Te rere o te moata parai
He nui te pānga o te ngaronga o ngā taputapu rehu ki te rere o te moata parai. I raro i te ōwehenga wai-rauemi kotahi, ka teitei ake te matotoru o te cellulose ether, ka iti ake te uara rere o te moata. , ko te tikanga ka teitei ake te matotoru o te cellulose ether, ka nui ake te ātete o te moata, ā, ka nui ake te kakahu o ngā taputapu. Nō reira, mō te hanganga mīhini o te moata parai, he pai ake te iti o te matotoru o te cellulose ether.
Te ātete totoro o te moata parai
I muri i te rehu o te moata parai ki te pakitara, ki te kore e pai te ātete o te moata ki te totohu, ka totohu te moata, ka paheke rānei, ka pā kino ki te papatahi o te moata, ka raru nui ai te hanganga o muri mai. Nō reira, me tino pai te ātete o te moata pai ki te thixotropy me te totohu. I kitea i roto i te whakamātautau i muri i te whakatūnga poutū o te cellulose ether me te matotoru o te 50,000 me te 100,000, ka paheke tika ngā taera ki raro, engari kāore te cellulose ether me te matotoru o te 150,000 me te 200,000 i paheke. Kei te whakatū poutū tonu te koki, ā, kāore he paheke e puta.
Te kaha o te moata parai
Mā te whakamahi i te 50,000, 100,000, 150,000, 200,000, me te 250,000 cellulose ethers hei whakarite i ngā tauira moata parai mō te hanga mīhini, i kitea ai me te pikinga ake o te matotoru o te cellulose ether, ka heke te uara kaha o te moata parai. Nā te mea ka hangaia e te cellulose ether he otinga matotoru teitei i roto i te wai, ā, ka uru mai he maha o ngā mirumiru hau pumau i te wā e whakaranua ana te moata. I muri i te whakapakeketanga o te sima, ka hangaia e ēnei mirumiru hau he maha o ngā āputa, ka whakaiti i te uara kaha o te moata. Nō reira, me taea e te moata parai e tika ana mō te hanga mīhini te whakatutuki i te uara kaha e hiahiatia ana e te hoahoa, ā, me whiriwhiri he cellulose ether e tika ana.
