Hydroxypypyl methylcellulosenthawi zambiri imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Ngakhale anthu ambiri samvetsa bwino, zimakhudza mafakitale osiyanasiyana. Munjira yomanga, nthawi zambiri imagwiritsidwa ntchito pokongoletsa khoma ndi zokongoletsera za ma stucco, zomangamanga zamakina, makamaka pamanja zokongoletsa, nthawi zambiri zimagwiritsidwa ntchito ngati zokongoletsera pulasitiki. Imakhala ndi gawo lalikulu lazotsatira ndipo limachepetsa kuchuluka kwa simenti yomwe imagwiritsidwa ntchito. Amagwiritsidwa ntchito popanga mafakitale, makamaka ogwiritsira ntchito otchinga, amatha kupanga mawonekedwe abwino ndi owala, osavuta kuchotsa ufa, etc., makamaka pakugwiritsa ntchito matope odzikongoletsa.
Mphoto yodzikongoletsera yokha imakhala makamaka yopanda matope owuma ndi matope osenda komanso kudziletsa. Kudziletsa kwake komanso kuthekera kokha ndikofunikira kwambiri kuti mukwaniritse zosanjikiza zosalala komanso zosalala. Pazinthu zodzipangitsa nokha, choyamba ziyenera kukhala ndi magwiridwe antchito abwino, ndipo amatha kukhalabe ndi ntchito yake yonse komanso luso lodziletsa munthawi yomanga. Mwanjira imeneyi, izi zimafunikira matope kuti atsimikizire mokwanira kukhazikika kwake ndi kufanana pakati pa nthawi ino. Kachiwiri, matope ayenera kukhala ndi mphamvu inayake, yomwe imaphatikizapo kubvala bwino komanso kukakamiza kwa maziko. Izi ndizofunikira kuti mugwiritse ntchito zida zodzilimbitsa nokha, ndipo kukwaniritsidwa kwa zinthu zomwe zimapangitsa kuti hydroxypropyl ethell ethelulose ether ether ether ether etherch etherting ndi kukwera nthawi yomanga.
Makutu apamwamba a hydroxpyuropyl meth Kuphatikiza apo, zotsatira za kukula kwa hydroxpyl methylcellulose zithanso kuwonjezera madzi am'madzi, potero kuwonjezera zokolola za matope. Matope okhathamira komanso konkriti wodziletsa, zomwe zimafuna kuti madzi akumadzi azitha, amafunikira mafayilo otsika a hydroxypropyll methylcelulose. Kutayika kotsika kwa cellulose ether kumatha kusewera bwino, komanso kukhala ndi magazi, komanso ali ndi ntchito yotaya magazi, yomwe ingawonetsetse kuti sizingakhudze zotsatira za matope odzilimbitsa okha, Ndipo posunga madzi kwambiri pamakhalidwe atha kupangitsa kuti chapamwamba chitha kukhala bwino, kuchepetsa matope a matope, ndikupewa ming'alu ndi zina.
Hydroxypypyl methylcellulose imagwiritsidwa ntchito kwambiri pazomangira zosiyanasiyana. Mukamagwiritsa ntchito matope okhaokha, ili ndi izi:
1. Magwiridwe osungirako madzi okwanira amatha kupereka matope omwe amadzilimbitsa okha, kusintha chibwibwi cha matope, onjezerani mphamvu yake yomanga, ndipo magwiridwe ake abwino kwambiri amachepetsa phulusa.
2. Kugwirizana kwamphamvu, koyenera kwa mitundu yonse ya zomangamanga, matope okhalitsa, kuchepetsa nthawi yowuma, kuchepetsa kuchuluka kwake kouma, ndikupewa mavuto monga kusokonekera ndi makhoma.
3.
4. Khalani ndi magwiridwe antchito abwino, mafayilo otsikahydroxypypyl methylcellulosesichingakhudze kuyenda kwa slurry, kovuta, kugwiritsa ntchito njira yabwino yosungirako madzi pambuyo podzilimbitsa, ndipo pewani kuwonongeka kwa ng'oma, ndikugwiririra magetsi a cellulose kwathunthu - luso lokhutira. Kuwongolera kuchuluka kwa madzi chingapangitse kukhala cholimba mwachangu komanso kuchepetsa shrinkage ndi kusokonekera.
