Hydroxypropyl methylcellulose HPMC imagwiritsidwa ntchito m'mafakitale ambiri. Ngakhale kuti anthu ambiri samazimvetsa bwino, zimakhudza mafakitale osiyanasiyana. Pomanga makampani omangamanga, nthawi zambiri amagwiritsidwa ntchito pomanga khoma ndi pulasitala. , Caulking ndi minda ina yomanga makina, makamaka pomanga zokongoletsera. Nthawi zambiri amagwiritsidwa ntchito poyika matailosi, mabulosi, ndi zokongoletsera zina zapulasitiki. Zili ndi mlingo waukulu womatira ndipo zimatha kuchepetsanso simenti yogwiritsidwa ntchito. Amagwiritsidwa ntchito mumakampani opanga zokutira. , Amagwiritsidwa ntchito kwambiri ngati thickener, akhoza kupanga wosanjikiza bwino ndi wowala, osati zosavuta kuchotsa ufa, kupititsa patsogolo kusanja ntchito, etc., makamaka ntchito m'munda womanga matope odzipangira okha.
Mtondo wodziyimira pawokha umakhala wosalala komanso wodzipangira yekha zinthu zapadera zamatope owuma, kudziphatika kwake, popeza kuthekera kofikira kusanjika kosasunthika komanso kosalala ndikofunikira kwambiri, pazinthu zabwino zodzipangira okha, kudzakhala nako. yoyenera ntchito ntchito, ndi kutha mu nthawi yomanga, kukhalabe ntchito yake yonse ya, ndi kudziletsa machiritso mphamvu, kotero, Izi zimafuna matope nthawi imeneyi mokwanira kuonetsetsa bata ndi chifanane, ndipo kachiwiri, chifukwa matope komanso ali ndi mphamvu zina, kuphatikizapo mphamvu yobereka ndi kumanga mphamvu ya pamwamba m'munsi, izi ndi zinthu zofunika kwa zipangizo pansi akhoza ntchito yachibadwa, kudziona mlingo kukhazikitsa izi, ntchito ya hydroxypropyl methyl cellulose etha olandiridwa kuti agwirizane nafe, akhoza kuchitapo kanthu. monga thickening analimbitsa adhesion, Iwo alinso makhalidwe a mkulu madzi posungira ndi yaitali kumanga nthawi.
Kuchuluka kwa mamasukidwe amphamvu a hydroxypropyl methyl cellulose ndikomwe kumapangitsanso kukhuthala kwa zinthu zosinthidwa za simenti, koma ngati mamasukidwe ake ndi akulu kwambiri, amakhudza kutulutsa ndi magwiridwe antchito azinthuzo. Kuphatikiza apo, kukhuthala kwa hydroxypropyl methyl cellulose kumathanso kukulitsa kufunikira kwa madzi pazinthu zopangira simenti, potero kumawonjezera kutulutsa kwamatope. Mtondo wodziyimira pawokha komanso konkriti wodziphatika, womwe umafunikira madzi ambiri, umafunika kukhuthala kochepa kwa hydroxypropyl methyl cellulose. Low mamasukidwe akayendedwe mapadi efa akhoza kuimba wabwino kuyimitsidwa tingalepheretse slurry kukhazikikamo, alinso ndi ntchito ya exudation, komanso akhoza kuonetsetsa kuti sizingakhudze kudziona mlingo matope otaya zotsatira, zomangamanga zosavuta, komanso ali ndi makhalidwe Gao Baoshui, amatha kupanga pamwamba pa otaya zotsatira zake zimakhala bwino kwambiri, kuchepetsa kuchepa kwa matope, kupewa kusenda mng'alu, ndi zina zotero.
Hydroxypropyl methyl cellulose imagwiritsidwa ntchito kwambiri mumitundu yonse yazomangamanga. Ikagwiritsidwa ntchito mumatope odziyimira pawokha, imakhala ndi izi:
1, magwiridwe antchito osungira madzi ambiri, amatha kutalikitsa nthawi yogwiritsira ntchito matope odziyimira pawokha, kupititsa patsogolo kulimba kwamatope, kukulitsa mphamvu zake zomangira, kugwirira ntchito bwino konyowa, kumatha kuchepetsa phulusa lapansi.
2, kuyanjanako ndi kolimba, koyenera kwa mitundu yonse ya zida zomangira, matope odziyimira pawokha, kuchepetsa nthawi yomira, kuchepetsa kutsika kwakuya, kupewa khoma ndi ng'oma yosweka ndi zovuta zina.
3, kupewa magazi, kungathandize kwambiri kuyimitsidwa, kupewa slurry mafunsidwe ndi ntchito bwino magazi.
4, sungani katundu wabwino, kukhuthala kochepa kwa hydroxypropyl methyl cellulose sikungakhudze kuyenda kwa slurry, kumanga kosavuta, ntchito yabwino yosungira madzi, kumatha kutulutsa bwino pambuyo pakudzikweza, kupewa kusweka kwa ng'oma, cellulose ether ndi magwiridwe antchito okhazikika. , kutsimikizira mokwanira zamadzimadzi abwino, komanso kutha kudziwongolera, Kuwongolera kuchuluka kwa madzi osungirako kungapangitse kulimba mwachangu ndikuchepetsa kuchepa ndi kusweka.
