Hydroxypropyl methyl cellulose i roto i te raima me te raima i runga i te raima

HPMC Hydroxypropyl methyl cellulose i roto i te kumete ciment me te gypsum slurry, ko te nuinga o te mahi ki te pupuri i te wai me te matotoru, ka taea te whakapai ake i te adhesion me te sag resistance o te slurry.

Ko te pāmahana o te hau, te pāmahana me te reeti pehanga hau ka pa ki te tere whakaetonga o te wai i roto i te kumete ciment me nga hua gypsum.Na i roto i nga wa rereke, ko te taapiri i te hydroxypropyl methyl cellulose he rite te nui o te hua pupuri wai he rerekee.I roto i te hanga raima, ka taea te whakarereke i te paanga pupuri wai o te slurry ma te whakanui ake, te whakaheke ranei i te nui o te HPMC.Ko te pupuri i te wai o te methyl cellulose ether i te wera nui he tohu nui hei wehewehe i te kounga o te methyl cellulose ether.

Ka taea e nga hua raupapa hydroxypropyl methyl cellulose pai te whakaoti i te raruraru o te pupuri wai i raro i te wera nui.I roto i te wa wera nui, ina koa i roto i nga waahi wera me te maroke me te hanga paparanga angiangi i runga i te taha paki, te hiahia mo te HPMC kounga teitei hei whakapai ake i te pupuri wai o te slurry;hydroxypropyl methyl cellulose (HPMC), he tino pai te tauritenga, he hauhau me te hāora nga roopu hydroxypropyl kua tohatoha noa i te taha o te mekameka cellulose, ka taea te whakapai ake i te hauwai me te ether hāora me te wai i runga i te puka honohono matua te kaha o te honohono hauwai, te hanga wai kore utu, kia pai ai te whakahaere i te rangi wera na te makuku ki te whakaeto, Te whakatutuki i te pupuri wai teitei.

Ko te kounga teitei o te hydroxypropyl methyl cellulose ka taea te marara i roto i te kumete ciment me nga hua raima, ka kohia nga matūriki totoka katoa, ka hanga he paparanga o te kiriata makuku, ka tukuna te makuku i roto i te turanga mo te wa roa, me te tauhohenga wai pararopi. , kia rite ki te whakarite i te kaha here me te kaha compressive o rauemi.

I roto i te hanga, ki te whakatutuki i te painga o te tiaki wai, me taapiri nga hua HPMC o te kounga teitei kia rite ki te tauira, ki te kore, ka tere rawa te whakamaroke na te iti rawa o te wai, te whakaheke kaha, te pakaru, te pahu me te whakaheke i te kounga. nga raruraru, engari ka piki ake ano te uaua o te hanga kaimahi.I te hekenga o te pāmahana, ka taea te whakaiti i te nui o te wai HPMC, a ka taea te whakatutuki i taua mana pupuri wai.
