Hydroxypropyl methylcellulose (HPMC) ndi ether ya cellulose yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera mu njira zingapo zamakemikolo. Ndi ufa woyera wopanda fungo, wopanda kukoma komanso wopanda poizoni womwe umatupa kukhala yankho la colloidal loyera kapena lamtambo pang'ono m'madzi ozizira. Lili ndi makulidwe, ma bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, superficial, moisturizing and protective colloid properties. Hydroxypropyl methyl cellulose ndi methyl cellulose zingagwiritsidwe ntchito mu zipangizo zomangira, makampani opanga utoto, utomoni wopangidwa, mafakitale a ceramic, mankhwala, chakudya, nsalu, ulimi, mankhwala a tsiku ndi tsiku ndi mafakitale ena.
Kugwiritsa ntchito kwakukulu kwa hydroxypropyl methylcellulose HPMC mu zipangizo zomangira:
1. Pulasitiki yopangidwa ndi simenti
⑴ Kumathandiza kuti pulasitiki ikhale yofanana, kupangitsa kuti pulasitiki ikhale yosavuta kupukutidwa, kumathandizira kuti isagwe, kumathandizira kuti madzi aziyenda bwino komanso kuti madzi azituluka bwino, komanso kumathandizira kuti ntchito igwire bwino ntchito.
⑵ Kusunga madzi ambiri, kukulitsa nthawi yosungira matope, kukonza magwiridwe antchito, komanso kuthandizira kuti matope azisungunuka komanso kulimba kuti apange mphamvu zambiri zamakanika.
⑶ Yang'anirani momwe mpweya umalowera kuti muchotse ming'alu pamwamba pa chophimbacho ndikupanga malo osalala bwino.
2. Zopangidwa ndi pulasitala ndi gypsum zopangidwa ndi gypsum
⑴ Kumathandiza kuti pulasitiki ikhale yofanana, kupangitsa kuti pulasitiki ikhale yosavuta kupukutidwa, kumathandizira kuti isagwe, kumathandizira kuti madzi aziyenda bwino komanso kuti madzi azituluka bwino, komanso kumathandizira kuti ntchito igwire bwino ntchito.
⑵ Kusunga madzi ambiri, kukulitsa nthawi yosungira matope, kukonza magwiridwe antchito, komanso kuthandizira kuti matope azisungunuka komanso kulimba kuti apange mphamvu zambiri zamakanika.
⑶ Yang'anirani kusinthasintha kwa matope kuti apange chophimba chabwino kwambiri pamwamba pake.
3. Simenti yopangira miyala
⑴ Limbikitsani kumatirira pamwamba pa miyala, onjezerani kusunga madzi, komanso onjezerani mphamvu ya matope.
⑵ Kukweza kukhuthala ndi kusinthasintha kwa kapangidwe kake, ndikuwongolera kapangidwe kake; matope okonzedwanso ndi cellulose ether ndi osavuta kupanga, amasunga nthawi yomanga komanso amachepetsa ndalama zomangira.
⑶ Cellulose ether yosunga madzi ambiri, yoyenera njerwa zomwe zimayamwa madzi ambiri.
4. Chodzaza mbale
⑴Kusunga madzi bwino kwambiri, kumawonjezera nthawi yotsegulira komanso kumawonjezera magwiridwe antchito. Mafuta ambiri, osavuta kusakaniza.
⑵ Kuonjezera kukana kufooka ndi kukana ming'alu, komanso kuonjezera ubwino wa pamwamba pa kupaka utoto.
⑶ Konzani bwino momwe malo olumikizirana amagwirira ntchito komanso kuti pakhale mawonekedwe osalala komanso osalala.
5. Guluu wa matailosi
⑴Zosakaniza zosavuta kuumitsa, sizimasakanikirana, zimawonjezera liwiro la ntchito, zimawonjezera magwiridwe antchito, zimasunga nthawi yogwirira ntchito ndikuchepetsa ndalama zogwirira ntchito.
⑵ Mwa kuwonjezera nthawi yotsegulira, kugwira ntchito bwino kwa matailosi kungawongoleredwe ndipo zotsatira zabwino kwambiri zomatira zitha kuperekedwa.
6. Zipangizo zodziyimira pansi
⑴Amapereka kukhuthala ndipo angagwiritsidwe ntchito ngati chowonjezera choletsa kusefukira kwa nthaka.
⑵Kupangitsa kuti madzi aziyenda bwino komanso kuti nthaka ikhale yolimba.
⑶ Kuwongolera kusunga madzi ndi kufupika, kuchepetsa ming'alu ndi kufupika kwa nthaka.
7. Utoto wopangidwa ndi madzi
⑴Pewani mvula yolimba ndikuwonjezera moyo wa chidebecho. Kukhazikika kwachilengedwe, kugwirizana bwino ndi zinthu zina.
⑵ Kumawonjezera kusinthasintha kwa madzi, kumapereka mphamvu zabwino zoletsa kusweka, zoletsa kugwa komanso zoletsa kutsetsereka, komanso kuonetsetsa kuti pamwamba pake pamakhala bwino kwambiri.
8. Ufa wa pepala lophimba
⑴ Sungunulani mwachangu popanda zibowo, zomwe ndi zabwino posakaniza.
⑵ imapereka mphamvu yolimba kwambiri.
9. Bolodi la simenti lotulutsidwa
⑴ Ili ndi mgwirizano wambiri komanso mafuta ambiri, ndipo imawonjezera luso la zinthu zotulutsidwa.
⑵ Imalimbitsa mphamvu zobiriwira, imalimbitsa madzi ndi kuchiritsa, komanso imawonjezera zokolola.
10. Zogulitsa za HPMC za matope osakaniza kale
Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka pa matope osakaniza kale chili ndi madzi abwino kuposa zinthu wamba zomwe zili mu matope osakaniza kale, zomwe zimapangitsa kuti zinthu zosapanga dzimbiri ziume bwino, komanso zimaletsa kwambiri kuchepa kwa mphamvu ya ma bond chifukwa cha kuumitsa kwambiri ndi kusweka komwe kumachitika chifukwa cha kuuma. HPMC ilinso ndi mphamvu yolowera mpweya. Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka pa matope osakaniza kale chili ndi thovu loyenera lolowetsedwa mpweya, lofanana komanso laling'ono, lomwe lingathandize kulimbitsa ndi kusalala kwa matope osakaniza kale. Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka pa matope osakaniza kale chili ndi mphamvu yochedwetsa, yomwe imatha kukulitsa nthawi yotsegulira matope osakaniza kale ndikuchepetsa zovuta zomangira. Hydroxypropyl methylcellulose (HPMC) ndi ether ya cellulose yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera mu njira zingapo zamakemikolo. Ndi ufa woyera wopanda fungo, wopanda kukoma komanso wopanda poizoni womwe umatupa kukhala yankho loyera kapena lamtambo pang'ono m'madzi ozizira. Ili ndi mphamvu zokhuthala, zomangira, zobalalitsa, zosakaniza, zopanga filimu, zoyimitsa, zokometsera, zopaka gelling, zapamwamba, zosunga chinyezi komanso zoteteza colloid. Hydroxypropyl methyl cellulose ndi methyl cellulose zingagwiritsidwe ntchito mu zipangizo zomangira, makampani opanga utoto, utomoni wopangidwa, mafakitale a ceramic, mankhwala, chakudya, nsalu, ulimi, mankhwala a tsiku ndi tsiku ndi mafakitale ena.
