Kodi hydroxypropyl ya methylcellulose ethercc imawoneka bwanji?

M'malovu, simenti matope ndi gypsum - hpmc hydroxpyl etherllulose etherllulose kukhala gawo lamadzi osakhazikika ndi kukula kwa slurry. Zinthu monga kutentha kwa mpweya, kutentha ndi kuthamanga kwa mphepo kumakhudza kuchuluka kwa madzi mu putet, simenti matope ndi gypsum. Chifukwa chake, nthawi zosiyanasiyana, pali kusiyana kwinanso m'madzi osungiramo zinthu zomwe zimapangidwa ndi HPMC yowonjezeredwa. Mu zomanga zina, kuchuluka kwa madziwo kumatha kusinthidwa ndikukulitsa kuchuluka kwa HPMC yowonjezeredwa.

Kusunga kwamadzi kwa methyl cellulose ether kumatentha kwambiri ndi chizindikiro chofunikira kusiyanitsa mtundu wa methyl cellulose ether. Zinthu zochulukirapo hpmc zimathetsa bwino vuto la madzi osungidwa kutentha kwambiri. Mu nyengo zotentha kwambiri, makamaka m'malo otentha ndi owuma ndi zomangamanga zowonda m'mbali mwa dzuwa, hpmc zapamwamba kwambiri zimafunikira kukonza chitetezo chamadzi cha slorry. HPMC yapamwamba kwambiri imatha kusintha madzi ako mu matope mu madzi omangidwa, potero amawongolera madzi ambiri omwe amayamba chifukwa cha nyengo yotentha komanso kukwaniritsa madzi ambiri.

Cellose yapamwamba kwambiri ya methyl imatha kukhala yofananira ndi mankhwala osokoneza bongo a simenti ndi gypsum, ndikukulani tinthu tating'onoting'ono, ndikupanga filimu yonyowa, ndipo madziwo adzamasulidwa pang'onopang'ono kwa nthawi yayitali. Kuchita masewera olimbitsa thupi kumachitika, potero, mphamvu zolimbana ndi mphamvu zolimba. Chifukwa chake, mu mamangidwe otentha otentha chilimwe, kuti mukwaniritse madzi osatsatira, ndikofunikira kuwonjezera zinthu zapamwamba za HPMC pamagawo okwanira malingana ndi mawonekedwe. Ngati HPMC yophatikizika imagwiritsidwa ntchito, kusakwanira kwamafuta, kuchepetsedwa mphamvu, kusokonekera, ndipo madothi angachitike chifukwa chowuma kwambiri. Mavuto Abwino monga ng'oma ndi zourira zimawonjezera zovuta zomanga antchito. Pamene kutentha madontho, kuchuluka kwa hpmc kuwonjezeredwa kumatha kuchepetsedwa pang'onopang'ono, ndipo madzi omwewo akwaniritsidwe.

Njira yomwe imachitika bwino imawongolera kukhazikitsa kwa HPMC, ndipo zomwe zili mu gawo lake ndizokwanira ndipo yunifolomu yake ndiyabwino kwambiri. Njira yake yamadzimadzi imamveka bwino komanso yowonekera, yokhala ndi ulusi waulere. Kugwirizana ndi ufa wa mphira, simenti, laimu ndi zinthu zina zazikulu zimakhala zolimba makamaka, zomwe zingapangitse zinthu zazikuluzikulu zimasewera. Komabe, HPMC yokhala ndi zovuta zambiri zimakhala ndi ulusi waulere waulere, kufalitsa magalimoto osasinthika, kusungidwa kwamadzi osawoneka bwino komanso zinthu zina, zomwe zimapangitsa madzi kukhala osinthika kutentha kwambiri. Komabe, otchedwa Hopmc (mtundu wa couse) wokhala ndi zodetsa zambiri ndizovuta kugwirizanitsana wina ndi mnzake, motero kusungidwa kwamadzi ndi zinthu zina ndizoyipa kwambiri. Ngati HPMC yosauka imagwiritsidwa ntchito, pamakhala zovuta monga mphamvu yotsika, nthawi yayifupi, yotsegulira, kuchepetsedwa, kovuta kwambiri, zomwe zingapangitse zovuta zomanga ndipo zimachepetsa bwino nyumbayo.
