Hydroxypropyll methylclulose imagwiritsidwa ntchito ngati chobalalitsa polyvinyl chloride, ndipo ndiye wamkulu wothandizira wothandizira pokonzekera PVC poyimitsidwa. Munjira yomanga yomanga, imagwiritsidwa ntchito makamaka pomanga makina ngati khoma, popata, kugwa, ndi zina.; Makamaka pomangako zinthu zokongoletsera, imagwiritsidwa ntchito poika matayala a ceramic, marble, ndi zokongoletsera pulasitiki. Imakhala yolumikizana kwambiri ndipo imatha kuchepetsa kuchuluka kwa simenti. . Amagwiritsidwa ntchito ngati thickiner mu makampani opanga utoto, zomwe zimatha kupanga mawonekedwe owoneka bwino komanso osakhazikika, kupewa ufa, kusintha magwiridwe antchito, ndi zina zambiri.
Mu simenti matope ndi gypsum-zochokera ku gyproxpyl, hydroxypropyl methyllulose makamaka gawo la kusungidwa kwamadzi ndikukula, zomwe zimatha kusintha mphamvu yolumikizana ndi kukhazikika kwa slurry. Zinthu monga kutentha kwa mpweya, kutentha ndi kuthamanga kwa mphepo kumakhudza kuchuluka kwa madzi mu matope a simenti ndi gypsum. Chifukwa chake, nthawi zosiyanasiyana, pali zosiyana zina mumadzi zosungidwa ndi ma hydroxypropyl owonjezera. Mu zomanga zina, kuchuluka kwa madziwo kumatha kusinthidwa ndikukulitsa kuchuluka kwa HPMC yowonjezeredwa. Kusunga kwamadzi kwa methyl cellulose ether kutentha kwambiri kumakhala chizindikiro chofunikira kusiyanitsa mtundu wa hydroxypropyl celyl ethel ether. Zabwino kwambiri hydroxpyl methylcellulose angapo zimatha kuthana bwino ndi 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.
Hydroxypropyll methylcellulose (hpmc) ili ndi kufanana. Magulu ake a methoxy ndi hydroxyprophoxy amagawidwa mogwirizana ndi ma cellulose molecular unyolo, womwe umatha kuwonjezera maatomu a oxygen pa hydroxyl ndi ma elther. Kutha kucheza ndi madzi kuti apange mahola a hydrojeni amasintha madzi omangidwa madzi omangidwa madzi obwera chifukwa cha nyengo yotentha komanso kutentha kwa madzi. Madzi amafunika kuti azitha kugwiritsa ntchito zinthu zina ngati simenti ndi gypsum. Kuchuluka kwa hpmc kumatha kusunga chinyontho mu matope kwa nthawi yayitali kuti makonzedwe ndi kuumilira upitirizebe.
Kuchuluka kwa hydroxypropyl methylcellulose (hpmc) ofunikira kuti abweze kokwanira madzi kutengera:
Kuyamwa kwa maziko osanjikiza
Kupanga matope
Matope osanjikiza makulidwe
Matope amafunikira
Nthawi Yokhazikika
Hydroxypylrose ikhoza kukhala mopanda fanizo komanso yolumikizidwa bwino matope a simenti ndi gypsum, ndikukulani filimu yonyowa, chinyontho m'munsi nthawi yayitali Kuchita mankhwala opangidwa ndi zinthu zopangidwa kumayambitsa bonga ndikulimbana ndi mphamvu ya zinthuzo.
Chifukwa chake, mu mamangidwe otentha kwambiri chilimwe, kuti mukwaniritse madzi a HPMC mokwanira mokwanira molingana ndi njira, ndi kubzala zoyambitsidwa ndi kuyanika kwambiri. Mavuto, komanso kuwonjezera zovuta zomangamanga. Pamene kutentha madontho, kuchuluka kwa HPMC yowonjezeredwa kumatha kuchepetsedwa pang'onopang'ono, ndipo madzi omwewo akwaniritsidwe.
