Udindo wa hydroxypropyl methylcellulose

Pogwiritsa ntchito zida zomangira, hydroxypropyl methyl cellulose HPMC ndi chowonjezera chomwe chimagwiritsidwa ntchito pomanga,hydroxypropyl methyl celluloseamagwiritsidwa ntchito kwambiri m'makampani, ndipo ali ndi mitundu yosiyanasiyana, hydroxypropyl methyl cellulose imatha kugawidwa mumtundu wamadzi ozizira komanso mtundu wotentha wosungunuka.

Madzi ozizira nthawi yomweyo HPMC angagwiritsidwe ntchito mu putty ufa, matope, guluu wamadzimadzi, utoto wamadzimadzi ndi mankhwala a tsiku ndi tsiku. Hot Sungunulani HPMC kawirikawiri ntchito youma ufa mankhwala ndi mwachindunji kusakaniza ufa youma ntchito yunifolomu, monga putty ufa ndi matope, hydroxypropyl methylcellulose angagwiritsidwe ntchito ankagwiritsa ntchito bwino ntchito simenti, gypsum ndi zina hydrated zomangira. M'matope opangidwa ndi simenti, imapangitsa kuti madzi asungidwe bwino, amawonjezera nthawi yokhazikika komanso nthawi yotseguka, komanso amachepetsa kuyimitsidwa kwamadzi.

Hydroxypropyl methylcellulose angagwiritsidwe ntchito pomanga zinthu kusakaniza ndi kumanga, ndi youma mix formulations akhoza kusakaniza mwamsanga ndi madzi mwamsanga kukwaniritsa kugwirizana ankafuna. Ma cellulose ether amasungunuka mwachangu popanda kugwa. Propyl methyl cellulose imatha kusakanizidwa ndi ufa wowuma muzomangamanga, imakhala ndi mawonekedwe a kubalalitsidwa kwamadzi ozizira, imatha kuyimitsa tinthu tating'onoting'ono bwino ndikupangitsa kuti chisakanizocho chikhale chabwino komanso chofananira. Kuphatikiza apo, imawonjezera lubricity ndi plasticity, imawonjezera machinability, komanso imathandizira kupanga zinthu. Kusungidwa kwamadzi kowonjezereka, nthawi yayitali yogwira ntchito, kumathandizira kupewa kuyenderera kwamatope ndi matailosi, kumatalikitsa nthawi yozizirira ndikuwongolera magwiridwe antchito.

Hydroxypropyl methylcellulose imapangitsa kuti zomatira za matailosi zikhale zolimba, zimathandizira kukana kwamatope ndi mafupa, osati kumangowonjezera mpweya mumatope, komanso kumachepetsa kwambiri kuthekera kwa kusweka, kumathanso kusintha Mawonekedwe a mankhwalawo komanso onjezerani ntchito ya anti-sag ya zomatira matailosi.
