Kusunga kwamadzi kuchokera ku hydroxypropyl methy cellose ndi imodzi mwazinthu zofunikira za hydroxypropyl celloluse. 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 osungiramo zinthu zomwe zimapangidwa ndi ma hydroxypropyl celyl.
Nthawi zambiri, mawidwe apamwamba a hydroxpyupyl methy cellulose, koma zotsatira zabwino zamadzi zidzakhalapo, koma zotsatira za mafayilo pamadzi zidzachepetsedwa pamene ma viscCon imaposa 100,000 MPA.S. Kwa hydroxypropyl methy cellulose yokhala ndi mawonekedwe oposa 100,000, ndikofunikira kuwonjezera kuchuluka kwa hydroxypropyl celyl celyse yowonjezera kuchuluka kwa madzi.
Pazomanga zina, kuchuluka kwa madziwo kumatha kusinthidwa ndikukulitsa kuchuluka kwa hydroxypropyl celyiluse. Hydroxypropyl methl cellulose malonda amatha kuthana bwino ndi vuto la madzi osungidwa kutentha kwambiri. Mu nyengo zotentha kwambiri, makamaka m'malo otentha ndi owuma ndi zomangira zowonda ndi ma hydroxypropyl oyenera kuwongolera madzi osungunuka.
Hydroxypypypyl methl cellulose ilinso limodzi. Magulu ake a methoxy ndi hydroxyprophoxy magulu amagawidwa motsatana ndi ma cellulose molecular unyolo. Itha kusintha maatomu a okosijeni pa hydroxyl ndi ma embi. Kutha kwa mayanjano amadzi kuti apange ma hydrojeni amatembenuza madzi opanda madzi amayenda m'madzi omangidwa, potero amayendetsa bwino madzi obwera chifukwa cha nyengo yotentha komanso kuti athe kusuntha kwamadzi kwambiri.
Hydroxypypypyl Methyl Callyl imatha kufalitsa mankhwala osokoneza bongo a simenti ndi gypsum, ndikukulani filimu yolimba, ndipo chinyontho m'munsi chimamasulidwa pang'onopang'ono kwa nthawi yayitali. Kuchita zinthu mozama kumachitika ndi zinthu zogulirapo, potero, mphamvu zolimbana ndi mphamvu za nkhaniyi. Chifukwa chake, mu mamangidwe otentha kwambiri, kuti akwaniritse madzi a Methi, ndikofunikira kuti muwonjezere mankhwala apamwamba kwambiri molingana ndi njira, kapena kuwonongeka kwamphamvu, komanso kuwonongeka kumachitika chifukwa chodetsa kwambiri. Mavuto apamwamba monga maso, osakhala ndi kugwa ndikuwonjezeranso zovuta zomanga ogwira ntchito. Pamene kutentha kumadontha, kuchuluka kwa hydroxypropyl meth celyl kuwonjezeredwa pang'onopang'ono, ndipo madzi omwewo amatha kukwaniritsidwa.
