Ntchito yomanga hpmc hydroxypropyl methylcellulose

KUKHALA KWAMBIRI
Hydroxypropyl Methyl Cellulose (HPMC) imagwiritsidwa ntchito nthawi zambiri ngati chowonjezera pomanga chifukwa imalepheretsa kulekanitsa komanso kupititsa patsogolo mgwirizano wa zigawo zopangira.Mu matope osakaniza owuma, mphamvu yowonjezereka imagwirizana ndi kukhuthala kwawo.HPMC imapereka kumata kwabwino kumatope onyowa.Izi zitha kukulitsa kwambiri kumamatira kwa matope onyowa pamtunda ndikuwongolera kukana kwa matope.
NTHAWI YOTULUKA KWATALILALI
Hydroxypropyl Methyl Cellulose (HPMC) imatha kuteteza madzi othamanga kwambiri komanso otsika kwambiri m'munsi mwa zinthu zopangidwa ndi simenti, zomwe zimapangitsa kuti madzi ambiri azikhala mumatope ndikuchita nawo gawo la simenti ya hydration.HPMC ili ndi mphamvu yosungira madzi yokhazikika pa kutentha kwakukulu, ngakhale kusintha kwa kutentha kozungulira kudzakhudza mphamvu yake yosungira madzi.Zinthu zina zapadera zimatha kugwirabe ntchito bwino m'malo otentha kwambiri.Muzinthu zopangidwa ndi gypsum komanso phulusa la calcium, ma cellulose ethers amakhalanso ndi gawo lofunikira pakuwonetsetsa kuti nthawi yawo yotseguka komanso kukula kwamphamvu.
KUGWIRITSA NTCHITO KWABWINO
Hydroxypropyl Methyl cellulose (HPMC) akhoza kwambiri kuonjezera thixotropic katundu wa matope dongosolo, amene amalola matope ndi kwambiri odana ndi sagging luso, potero kuwongolera yomanga Mwachangu, makamaka pomanga pa makoma.Kukana kwabwino kwa matope kumatanthauza kuti sipadzakhala kutsetsereka pamene matope amangidwa ndi makulidwe ochuluka;pa ntchito yoyika matailosi, zikutanthauza kuti matailosi omwe amaikidwa kukhoma sangasunthike chifukwa cha mphamvu yokoka.
