Instant hydroxypropyl methylcellulose ether idapangidwira zopangira madzi. Pamwamba pa hydroxypropyl methylcellulose ether amathandizidwa ndi glyoxal pansi pa kutentha kwina ndi pH mtengo. Hydroxypropyl methyl cellulose ether yomwe imagwiritsidwa ntchito motere imamwazikana m'madzi ozizira osalowerera popanda kutupa ndi kukhuthala, zomwe zimathandizira kuchedwetsa kutupa. Panthawiyi, njira yamadzimadzi imasunthidwa kwa mphindi 5-10 kapena Pamene malo a yankho (PH mtengo) asinthidwa kukhala alkaline, hydroxypropyl methylcellulose ether imayamba kutupa ndikupanga kukhuthala. Mtundu woterewu umatchulidwa kuti mtundu waposachedwa.
Makhalidwe a instant hydroxypropyl methylcellulose ndikuti akakumana ndi madzi ozizira, amafalikira mwachangu m'madzi ozizira, koma zimatenga nthawi kuti mamasukidwe ake akwere, chifukwa amangofalikira m'madzi koyambirira, ndipo samasungunuka m'madzi. chidziwitso chachikulu. Kukhuthala kwake kumafika pamtengo wapamwamba pafupifupi mphindi 20 kapena kuposerapo. Ubwino wa izi ndikuti umagwiritsidwa ntchito m'makampani apadera popanda kusakaniza ufa wouma, kapena pamene uyenera kusungunuka ndipo madzi otentha sangagwiritsidwe ntchito chifukwa cha zipangizo ndi zifukwa zina. Instant hydroxypropyl methylcellulose amathetsa vutoli.
Instant-mtundu hydroxypropyl methylcellulose amamwazikana m'madzi (kubalalika digiri ndi 100%), amasungunula mwamsanga, si clumping, makamaka pambuyo siteji, njira colloidal ndi mkulu transparency (mpaka 95%) ndi kusasinthasintha lalikulu, amene amathetsa mavuto. m'machitidwe othandiza. Zoletsa, kukulitsa gawo la ntchito, monga kugwiritsa ntchito guluu yomanga, kugwiritsa ntchito zosakaniza zamadzimadzi, ndi magawo apadera monga kutsuka kwamankhwala tsiku lililonse.
Tayambitsa zida zopangira zida zapamwamba kwambiri zapadziko lonse lapansi, tili ndi mzere wamakono wopanga ma cellulose ether ndi ufa wa latex wopangidwanso, ndikuwonetsetsa kupatsa ogwiritsa ntchito zinthu zokhutiritsa ndi machitidwe ake okhwima owongolera, makina oyesera komanso ntchito yabwino pamalopo. Tsopano zinthu zotsogola ndi hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether HPS, redispersible latex powder series. Zogulitsazo zimagwiritsidwa ntchito kwambiri pomanga, makampani opanga mankhwala, utoto, makampani opanga mankhwala tsiku ndi tsiku, mafakitale ankhondo ndi madera ena, ndipo amapangidwa kukhala othandizira opanga mafilimu, zomatira, dispersants, stabilizers, thickeners, etc.
Kudalira khalidwe lake la mankhwala ndi udindo wake ndi chikoka mu ufa youma zomangira zomangira makampani zowonjezera, ndi pansi pa maziko a nthawi zonse kukhalabe ndi cholinga makampani khalidwe poyamba, tsopano kugwirizana ndi mayiko ndi zoweta odziwika opanga mankhwala owonjezera. Ntchito zothandizira: ulusi wa polypropylene, ulusi wa Wood, wowuma wosinthika ether, ufa wa polyvinyl mowa, defoamer ya ufa, chochepetsera madzi, choletsa madzi, calcium formate ndi zina zowonjezera ufa.
