Whakamahinga Paura HpmcKa taea te whakamararatia kia rite me te whai hua ki te kumete ciment me nga hua gypsum, ka takai i nga matūriki totoka katoa ka hanga he kiriata makuku.Ka tukuna te makuku i roto i te turanga i roto i te waa roa, ka uru ki te tauhohenga whakamakuku me nga rawa cimentitious parakore, na reira ka whakapumau i te kaha hononga me te kaha o te kopiri o nga rawa.
Na reira, i roto i te pāmahana teitei hanga raumati, i roto i te tikanga ki te whakatutuki i te pānga pupuri wai, he mea tika ki te tāpiri rawaka moni ohydroxypropyl methyl cellulosee ai ki te ture, ki te kore ka puta nga raru o te kounga penei i te iti o te whakamakuku, te whakaheke i te kaha, te pakaruhanga, te pupuhi, me te wehenga na te whakamaroke tere ka puta, ka piki ake ano te uaua o nga kaimahi ki te hanga.I te hekenga o te pāmahana, ka taea te whakaiti i te nui o te hydroxypropylmethylcellulose, a ka taea te whakatutuki i te painga o te pupuri wai.
Ko te pupuri wai o te hydroxypropyl methyl cellulose ka awehia e te pāmahana me nga mea e whai ake nei:
1. Homogeneity o te hydroxypropyl methyl cellulose
He riteritehydroxypropyl methyl cellulose, Ko te roopu Methoxy me te hydroxypropyl ka tohatoha noa, a he nui te tere o te pupuri wai.
2. Te pāmahana o te kiri wera HPMC
He nui te pāmahana me te reiti pupuri wai nui o te waiariki;Engari, he iti te utu pupuri wai.
3. Hydroxypropylmethylcellulosepokey
Ina te pokey oHPMCka piki, ka piki hoki te reiti pupuri wai;Ka tae te pokey ki tetahi taumata, ka kaha haere te piki o te pupuri wai.
4. Te rahinga taapiri o te hydroxypropyl methyl cellulose
Ko te nui ake o te hydroxypropyl methyl cellulose ka taapirihia, ka nui ake te reeti 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;I te pikinga ake o te moni taapiri, ka puhoi te piki haere o te reiti pupuri wai
