Kusiyana kwa chitsanzo cha Hydroxypropyl methylcellulose

Hydroxypropyl methyl celluloseimagawidwa m'mitundu iwiri ya madzi ozizira omwe amasungunuka nthawi yomweyo.

1. Mndandanda wa Gypsum Mu zinthu zamtundu wa gypsum, ma cellulose ether amagwiritsidwa ntchito makamaka kusunga madzi ndikuwonjezera kusalala. Pamodzi amapereka mpumulo. Imatha kuthetsa kukayikira kwa kusweka kwa ng'oma ndi mphamvu yoyambirira panthawi yogwiritsa ntchito, ndikuwonjezera nthawi yogwira ntchito.

2. Mu putty ya zinthu za simenti, cellulose ether imagwira ntchito makamaka yosunga madzi, kumamatira ndi kusalala, kupewa ming'alu ndi kutaya madzi chifukwa cha kutayika kwa madzi ambiri, ndipo zonsezi pamodzi zimathandizira kumamatira kwa putty ndikuchepetsa kuchitika kwa njira yomanga, ndikupangitsa kuti zomangamanga zikhale bwino.

3. Mu makampani opanga utoto wa latex, ma ether a cellulose angagwiritsidwe ntchito ngati zinthu zopangira filimu, zothina, zosakaniza ndi zokhazikika, kuti zikhale zolimba bwino, zigwire bwino ntchito, zimamatira bwino komanso PH, komanso zimakhala ndi mphamvu yokweza pamwamba. Imagwiranso ntchito bwino ikasakanizidwa ndi zinthu zachilengedwe, ndipo kusunga kwake madzi ambiri kumapangitsa kuti ikhale yabwino kwambiri potsuka ndi kuyeretsa.

4. Chothandizira pa interfacial chimagwiritsidwa ntchito makamaka ngati chokhuthala, chomwe chingawongolere mphamvu yokoka ndi kumeta, kukonza chophimba pamwamba, ndikuwonjezera mphamvu yomatira ndi yolumikizana.

5. Cellulose ether yomwe ili mu pepalali imayang'ana kwambiri pakugwirizanitsa ndi kuwonjezera mphamvu, zomwe zimapangitsa kuti matopewo azigwiritsidwa ntchito mosavuta komanso kukonza magwiridwe antchito. Mphamvu yoletsa kutsika, ntchito yabwino yosunga madzi imatha kutalikitsa nthawi yogwirira ntchito ya matopewo, kuonjezera kukana kufupika ndi kusweka, kuonjezera kuchuluka kwa pamwamba ndikuwongolera mphamvu ya matopewo.

6, Zitsulo za uchi Mu zitsulo zatsopano za uchi, chinthuchi chimakhala chosalala, chosunga madzi komanso champhamvu.

7. Kuwonjezeka kwa sealant, suture cellulose ether kumapangitsa kuti ikhale ndi m'mphepete wabwino kwambiri, kuchepetsa kuchepa komanso kukana kuwonongeka kwambiri, komanso kuteteza deta yoyambira ku kuwonongeka kwa makina, kuteteza kukhudzidwa kwa kunyowa pa zomangamanga zonse.

8. Kukhazikika kwa kukhazikika kwa ether ya cellulose yodziyimira payokha kumatsimikizira kusinthasintha kwabwino komanso luso lodziyimira payokha, ndipo kuchuluka kwa madzi ogwirira ntchito kumathandizira kuti ikhazikike mwachangu ndikuchepetsa ming'alu ndi kufupikitsa.

9. Mtondo wopaka pulasitala umasunga madzi ambiri kuti unyowetse simenti mokwanira, uwonjezere mphamvu ya chigwirizano, komanso nthawi yomweyo umawonjezera mphamvu yomangirira ndi yodula, zomwe zimapangitsa kuti ntchito yomanga ikhale yabwino kwambiri komanso kuti ntchitoyo ikhale yogwira ntchito bwino.

10. Kusunga madzi ambiri kwa guluu wa matailosi sikufuna kuti matailosi ndi maziko ake azilowetsedwa kapena kunyowetsedwa, zomwe zimapangitsa kuti matailosi ndi maziko ake azigwirana bwino kwambiri. Nthawi yomanga matope ndi yayitali, kapangidwe kake ndi koyenera komanso kofanana, kapangidwe kake ndi kosavuta, ndipo kali ndi njira yabwino kwambiri yopewera kusamuka.
