Hydroxypropyl methylcellulosenthawi zambiri amagwiritsidwa ntchito m'mafakitale osiyanasiyana. Ngakhale kuti anthu ambiri samazimvetsa bwino, zimakhudza mafakitale osiyanasiyana. Pomanga zomangamanga, nthawi zambiri amagwiritsidwa ntchito pomanga khoma ndi zokongoletsera za stucco, Caulking ndi minda ina yomanga makina, makamaka pomanga zokongoletsera, nthawi zambiri amagwiritsidwa ntchito popanga matayala, marble, ndi zokongoletsera zina zapulasitiki. Ili ndi digiri yapamwamba yomatira ndipo imatha kuchepetsa kuchuluka kwa simenti yomwe imagwiritsidwa ntchito. Amagwiritsidwa ntchito mu makampani ❖ kuyanika, makamaka ntchito monga thickener, akhoza kupanga wosanjikiza bwino ndi yowala, osati zosavuta kuchotsa ufa, kusintha mlingo ntchito, etc., makamaka ntchito m'munda womanga matope kudzikonda leveling.
Mphotho ya mchenga wodziyimira pawokha makamaka ndi chinthu chapadera chamatope chowuma chowuma chokhala ndi magwiridwe antchito odzipangira okha. Maluso ake odzipangira okha komanso odzipangira okha ndi ofunikira kwambiri kuti akwaniritse malo osasunthika komanso osalala. Pazinthu zabwino zodzipangira okha, choyamba Iyenera kukhala ndi magwiridwe antchito oyenera, ndikutha kusunga magwiridwe ake onse ndikudzichiritsa yokha mkati mwa nthawi yomanga. Mwanjira iyi, izi zimafuna matope kuti atsimikizire kukhazikika kwake komanso kufanana kwake mkati mwa nthawiyi. Kachiwiri, matope ayenera kukhala ndi mphamvu zina, zomwe zimaphatikizapo mphamvu yonyamula ndi mphamvu yomangira pansi. Izi ndizomwe zimayenera kugwiritsidwa ntchito mwachizolowezi cha zida zodziyimira pawokha, ndipo kukwaniritsidwa kwa zinthu izi pakudzikweza kumafuna hydroxypropyl kuwonjezera kwa methyl cellulose ether kumatha kukhuthala ndikuwonjezera kukhuthala, komanso kumakhala ndi mawonekedwe a kusunga madzi ambiri ndikutalikitsa. nthawi yomanga.
Kuchuluka kwa mamasukidwe amphamvu a hydroxypropyl methylcellulose, kumapangitsanso kukhuthala kwa zinthu zosinthidwa za simenti, koma ngati mamasukidwe ake ndi okwera kwambiri, zimakhudza kutulutsa ndi magwiridwe antchito azinthuzo. Kuphatikiza apo, kukhuthala kwa hydroxypropyl methylcellulose kumathanso kukulitsa kufunikira kwa madzi pazinthu zopangira simenti, potero kumawonjezera zokolola zamatope. Mtondo wodziyimira pawokha komanso konkriti wodziphatika, womwe umafunikira madzi ochulukirapo, umafunikira kukhuthala kochepa kwa hydroxypropyl methylcellulose. The low-viscosity cellulose ether imatha kusewera bwino kuyimitsa, kuteteza slurry kuti isakhazikike, komanso imakhala ndi ntchito yamagazi, yomwe imatha kuonetsetsa kuti sichingakhudze zotsatira za matope odziyimira pawokha, ndizosavuta kupanga, ndipo imakhala ndi madzi osungiramo madzi Makhalidwewa amatha kupanga mawonekedwe apamwamba atatha kuwongolera bwino, kuchepetsa kuchepa kwa matope, ndikupewa kupukuta ming'alu ndi zina zotero.
Hydroxypropyl methylcellulose imagwiritsidwa ntchito kwambiri pazomangira zosiyanasiyana. Ikagwiritsidwa ntchito mumatope odzipangira okha, imakhala ndi izi:
1. Kusunga madzi ochuluka kungathe kutalikitsa nthawi yogwiritsira ntchito matope odziyendetsa okha, kumapangitsa kuti matope azikhala olimba, kuwonjezera mphamvu zomangirira, komanso kuchita bwino kwambiri kwa matope kungachepetse phulusa lokwera.
2. Kugwirizana kwamphamvu, koyenera kwa mitundu yonse ya zipangizo zomangira, matope odzipangira okha, kuchepetsa nthawi yomira, kuchepetsa kuyanika kwake kwa shrinkage, ndi kupewa mavuto monga kung'amba ndi ng'oma ya makoma ndi pansi.
3. Kupewa magazi, kungathandize kwambiri kuyimitsidwa, kuteteza slurry ku sedimentation ndi bwino magazi ntchito.
4. Pitirizani kuyenda bwino, kukhuthala kochepa kwahydroxypropyl methylcellulosesizingakhudze otaya slurry, yomanga mosavuta, yeniyeni ntchito madzi posungira ntchito, akhoza kutulutsa zotsatira zabwino pamwamba pambuyo kudzikonda leveling, ndi kupewa akulimbana pa nkhani ya ng'oma, khola kugwirizana ntchito ya cellulose ether mokwanira zimatsimikizira fluidity wabwino ndi kudzikonda. - luso lokulitsa. Kuwongolera kuchuluka kwa kusunga madzi kumatha kulimbitsa msanga ndikuchepetsa kuchepa ndi kusweka.
