Hydroxypropyl methylcellulose (HPMC) ndi ether yosakhala ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo zama mankhwala. Ndi ufa woyera wopanda fungo, wopanda poizoni komanso wopanda poizoni womwe umatuluka m'madzi ozizira kapena owoneka bwino. Ili ndi kukhuthala, kulumikiza, kubalalika, emulsifying, kupanga filimu, kuyimitsa, kutsatsa, gelling, zapamwamba, kusunga chinyezi komanso kuteteza colloid. Hydroxypropyl methyl cellulose ndi methyl cellulose angagwiritsidwe ntchito pomanga, mafakitale utoto, utomoni kupanga, makampani ceramic, mankhwala, chakudya, nsalu, ulimi, tsiku mankhwala ndi mafakitale ena.
Kugwiritsa ntchito kwakukulu kwa hydroxypropyl methylcellulose HPMC muzomangamanga:
1. pulasitala wopangidwa ndi simenti
⑴ Konzani kugwirizana, pangitsa kuti pulasitala ikhale yosavuta kugwedezeka, sinthani kulimba kwa madzi, onjezerani madzi ndi kutulutsa mpweya, ndikuwongolera ntchito bwino.
⑵ Kusunga madzi ambiri, kukulitsa nthawi yosungiramo matope, kuwongolera magwiridwe antchito, komanso kuwongolera kuyatsa ndi kulimba kwamatope kuti apange mphamvu zamakina.
⑶ Yang'anirani kuyambitsa kwa mpweya kuti muchotse ming'alu pamtunda ndikupanga malo abwino osalala.
2. Zopangidwa ndi gypsum ndi gypsum
⑴ Konzani kugwirizana, pangitsa kuti pulasitala ikhale yosavuta kugwedezeka, sinthani kulimba kwa madzi, onjezerani madzi ndi kutulutsa mpweya, ndikuwongolera ntchito bwino.
⑵ Kusunga madzi ambiri, kukulitsa nthawi yosungiramo matope, kuwongolera magwiridwe antchito, komanso kuwongolera kuyatsa ndi kulimba kwamatope kuti apange mphamvu zamakina.
⑶ Yang'anirani kusasinthasintha kwa matope kuti apange zokutira zoyenera pamwamba.
3. Dongo la zomangamanga
⑴ Limbikitsani kumamatira ndi pamwamba pamiyala, onjezerani madzi osungira, ndikuwonjezera mphamvu ya matope.
⑵ Kupititsa patsogolo mafuta ndi pulasitiki, ndikuwongolera zomangamanga; matope opangidwa bwino ndi cellulose ether ndi osavuta kupanga, amapulumutsa nthawi yomanga komanso amachepetsa ndalama zomanga.
⑶ Kuchuluka kwa madzi osungira cellulose ether, koyenera ku njerwa zomwe zimayamwa madzi ambiri.
4. Plate joint filler
⑴Kusunga madzi kwabwino, kutalikitsa nthawi yotsegulira ndikuwongolera magwiridwe antchito. Mafuta okwera kwambiri, osavuta kusakaniza.
⑵ Sinthani kukana kwa shrinkage ndi kukana ming'alu, sinthani mawonekedwe a pamwamba.
⑶ Sinthani kumamatira kwa malo omangirira ndikupereka mawonekedwe osalala komanso osalala.
5. Zomatira matailosi
⑴Zosakaniza zosavuta kuziwumitsa, zosaphatikizika, onjezerani liwiro la ntchito, sinthani ntchito yomanga, sungani nthawi yogwira ntchito ndikuchepetsa mtengo wogwirira ntchito.
⑵ Potalikitsa nthawi yotsegulira, kuwongolera kwa matayala kumatha kuwongolera komanso kumamatira kwabwino kungaperekedwe.
6. Zida zodziyimira pawokha
⑴Patsani mamasukidwe akayendedwe ndipo atha kugwiritsidwa ntchito ngati zowonjezera zotsutsana ndi sedimentation.
⑵Kupititsa patsogolo kutulutsa kwamadzimadzi ndikuwongolera bwino pakukonza pansi.
⑶ Kuwongolera kusungidwa kwa madzi ndi kuchepa, kuchepetsa ming'alu ndi kuchepera kwa nthaka.
7. Utoto wamadzi
⑴Pewani mvula yolimba ndikutalikitsa moyo wa chidebe cha chinthucho. Kukhazikika kwakukulu kwachilengedwe, kuyanjana kwakukulu ndi zigawo zina.
⑵ Sinthani madzimadzi, perekani zabwino zotsutsa-splash, anti-sagging ndi kusanja, ndikuwonetsetsa kutha kwapamwamba.
8. Wallpaper Ufa
⑴ Sungunulani mwachangu popanda zotupa, zomwe ndi zabwino kusakaniza.
⑵ perekani mphamvu yolumikizana kwambiri.
9. Bolodi la simenti yowonjezera
⑴ Imakhala ndi mgwirizano wambiri komanso wothira mafuta, ndipo imapangitsa kuti zinthu zotuluka zitheke.
⑵ Kupititsa patsogolo mphamvu zobiriwira, kulimbikitsa ma hydration ndi machiritso, ndikuwonjezera zokolola.
10. Zinthu za HPMC zamatope osakaniza okonzeka
Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka popanga matope osakaniza chimakhala ndi madzi osungira bwino kuposa zinthu wamba mumatope osakanikirana, kuwonetsetsa kuti zinthu za cementitious hydration zimakwanira, ndikulepheretsa kwambiri kutsika kwamphamvu kwa ma bond chifukwa cha kuyanika kwambiri komanso kusweka komwe kumachitika chifukwa cha kuyanika. HPMC imakhalanso ndi mphamvu yolowetsa mpweya. Chopangidwa ndi HPMC chomwe chimagwiritsidwa ntchito makamaka pamatope osakaniza okonzeka chimakhala ndi kuchuluka koyenera kwa mpweya, yunifolomu ndi thovu laling'ono la mpweya, zomwe zimatha kupititsa patsogolo mphamvu ndi kusalaza kwa matope okonzeka osakaniza. Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka pamatope osakaniza okonzeka chimakhala ndi vuto linalake, lomwe limatha kutalikitsa nthawi yotsegulira matope osakanikirana ndikuchepetsa zovuta zomanga. Hydroxypropyl methylcellulose (HPMC) ndi ether yosakhala ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo zama mankhwala. Ndi ufa woyera wopanda fungo, wopanda poizoni komanso wopanda poizoni womwe umatuluka m'madzi ozizira kapena owoneka bwino. Ili ndi kukhuthala, kulumikiza, kubalalika, emulsifying, kupanga filimu, kuyimitsa, kutsatsa, gelling, zapamwamba, kusunga chinyezi komanso kuteteza colloid. Hydroxypropyl methyl cellulose ndi methyl cellulose angagwiritsidwe ntchito pomanga, mafakitale utoto, utomoni kupanga, makampani ceramic, mankhwala, chakudya, nsalu, ulimi, tsiku mankhwala ndi mafakitale ena.
