Momwe mungasankhire HPMC kuchokera ku kusunga madzi!

Kusungidwa kwa madzi kuchokera kuHydroxypropyl Methyl cellulosendi chimodzi mwa zinthu zofunika kwambiri za Hydroxypropyl Methyl Cellulose. Zinthu monga kutentha kwa mpweya, kutentha ndi liwiro la mphepo zimakhudza kuchuluka kwa madzi omwe amasungunuka mu simenti ndi zinthu zopangidwa ndi gypsum. Chifukwa chake, m'nyengo zosiyanasiyana, pali kusiyana pakati pa momwe madzi amasungidwira ndi kuchuluka komweko kwa Hydroxypropyl Methyl Cellulose.

Kawirikawiri, kukhuthala kwa Hydroxypropyl Methyl Cellulose kukakwera, kumakhala bwino kuti madzi azisungidwa bwino, koma kukhuthala kwa madzi azisungidwa kudzachepa pamene kukhuthalako kupitirira 100,000 mpa. Kwa Hydroxypropyl Methyl Cellulose yokhala ndi kukhuthala kopitilira 100,000, ndikofunikira kuwonjezera kuchuluka kwa Hydroxypropyl Methyl Cellulose kuti muwonjezere kwambiri kuchuluka kwa madzi omwe amasungidwa.

Mu kapangidwe kake, mphamvu yosungira madzi mu slurry ikhoza kusinthidwa powonjezera kapena kuchepetsa kuchuluka kwa Hydroxypropyl Methyl Cellulose. Zogulitsa za Hydroxypropyl Methyl Cellulose zimatha kuthetsa vuto la kusunga madzi mu kutentha kwambiri. Mu nyengo yotentha kwambiri, makamaka m'malo otentha ndi ouma komanso kapangidwe kowonda kumbali ya dzuwa, hydroxypropyl methylcellulose yapamwamba imafunika kuti madzi asunge bwino mu slurry.

Hydroxypropyl Methyl Cellulose yapamwamba kwambiri ili ndi kufanana kwabwino kwambiri. Magulu ake a Methoxy ndi Hydroxypropoxy amagawidwa mofanana pamzere wa maselo a cellulose. Imatha kukonza maatomu a okosijeni pa ma hydroxyl ndi ether bonds. Kuthekera kwa mgwirizano wamadzi kupanga ma hydrogen bonds kumasintha madzi omasuka kukhala madzi omangika, motero kumawongolera bwino kuuluka kwa madzi komwe kumachitika chifukwa cha nyengo yotentha kwambiri ndikupangitsa kuti madzi azisungidwa kwambiri.

Mapangidwe apamwambahydroxypropyl Methyl celluloseZingathe kufalikira mofanana komanso moyenera mu simenti ndi zinthu zopangidwa ndi gypsum, kukulunga tinthu tonse tolimba, ndikupanga filimu yonyowa, ndipo chinyezi chomwe chili pansi chidzatulutsidwa pang'onopang'ono kwa nthawi yayitali. Kuthira madzi kumachitika ndi zinthu zopangidwa ndi gelling, motero kuonetsetsa kuti zinthuzo zimakhala zolimba komanso zolimba. Chifukwa chake, pomanga kutentha kwambiri kwa chilimwe, kuti madzi asungidwe bwino, ndikofunikira kuwonjezera zinthu zapamwamba za Hydroxypropyl Methyl Cellulose mokwanira malinga ndi njira yopangira, apo ayi, madzi osakwanira, mphamvu yochepa, ndi ming'alu zidzachitika chifukwa cha kuumitsa kwambiri. Mavuto abwino monga kukumba, kukumba ndi kugwa kumawonjezeranso zovuta zomanga kwa ogwira ntchito. Pamene kutentha kukutsika, kuchuluka kwa Hydroxypropyl Methyl Cellulose komwe kumawonjezeredwa kumatha kuchepetsedwa pang'onopang'ono, ndipo zotsatira zomwezo zosungira madzi zitha kupezeka.
