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.Lili ndi makulidwe, kumanga, kubalalika, emulsifying, kupanga mafilimu, kuyimitsa, kutsatsa, kutsekemera, kugwiritsira ntchito pamwamba, kusunga chinyezi komanso kuteteza colloid.Hydroxypropyl methylcellulose ndi methylcellulose angagwiritsidwe ntchito zomangira, makampani utoto, kupanga utomoni, makampani ceramic, mankhwala, chakudya, nsalu, ulimi, tsiku mankhwala ndi mafakitale ena.
Chemical formula:
Hydroxypropylmethylcellulose (HPMC)[C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x
Kugwiritsa ntchito kwakukulu kwa hydroxypropyl methylcellulose HPMC muzomangamanga:
1. pulasitala yopangidwa 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. Mtondo wa Masonry
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 ndikuchepetsa ndalama zomanga.
⑶ Kuchuluka kwamadzi osungira cellulose ether, koyenera ku njerwa zomwe zimayamwa madzi ambiri.
4. Panel olowa filler
⑴Kusunga madzi kwabwino, kutalikitsa nthawi yotsegulira ndikuwongolera magwiridwe antchito.Mafuta okwera, 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 pa matailosi ⑴Zosakaniza zosakaniza zosavuta kuziwumitsa, zopanda zotupa, kuwonjezera liwiro la ntchito, kukonza magwiridwe antchito, kupulumutsa nthawi yogwira ntchito komanso kuchepetsa mtengo wogwirira ntchito.⑵ Potalikitsa nthawi yotsegulira, kuwongolera kwa matayala kumatha kuwongolera komanso kumamatira kwabwino kungaperekedwe.
6. Zida zodziyimira pawokha ⑴ zimapereka kukhuthala ndipo zitha 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 wotengera madzi ⑴Pewani mvula yolimba ndi kutalikitsa 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 (1) ili ndi mgwirizano wapamwamba komanso wokometsera, ndipo imapangitsa kuti machinability azinthu zowonjezera.⑵ Kupititsa patsogolo mphamvu zobiriwira, kulimbikitsa ma hydration ndi machiritso, ndikuwonjezera zokolola.
10. HPMC mankhwala operekedwa kwa okonzeka osakaniza matope mankhwala HPMC odzipereka okonzeka matope matope ndi bwino madzi posungira mu matope okonzeka osakaniza kuposa zinthu wamba, kuonetsetsa hydration zokwanira inorganic cementitious zipangizo, kuteteza kwambiri kuchepetsa mphamvu chomangira chifukwa cha kuyanika kwambiri. , ndi Ming'alu zomwe zimayamba chifukwa cha kuyanika kuchepa.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, lomwe lingathe kupititsa patsogolo mphamvu ndi kusalaza kwamatope 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.
