Kugwiritsa ntchito kwakukulu kwa hydroxypropyl methylcellulose HPMC muzomangamanga:
1. pulasitala yopangidwa ndi simenti
(1) Limbikitsani kugwirizana, pangitsa pulasitala kukhala yosavuta kupaka, kuthandizira kuti musagunde, onjezerani madzimadzi ndi kutulutsa mpweya, komanso kupititsa patsogolo ntchito.
(2) Kusunga madzi kwambiri, kukulitsa nthawi yoyika matope, kuwongolera magwiridwe antchito, komanso kuwongolera mphamvu zamakina amatope amadzimadzi ndi kulimba.
(3) Yang'anirani kuyambitsa mpweya kuti muchotse ming'alu pamwamba pa zokutira kuti mupange malo osalala omwe mukufuna.
2. Zopangidwa ndi gypsum ndi gypsum
(1) Limbikitsani kugwirizana, pangitsa pulasitala kukhala yosavuta kupaka, kuthandizira kuti musagunde, onjezerani madzimadzi ndi kutulutsa mpweya, komanso kupititsa patsogolo ntchito.
(2) Kusunga madzi kwambiri, kukulitsa nthawi yoyika matope, kuwongolera magwiridwe antchito, komanso kuwongolera mphamvu zamakina amatope amadzimadzi ndi kulimba.
(3) Kuwongolera kufanana kwa kusinthasintha kwa matope kuti apange chophimba chofunidwa pamwamba.
3. Dongo la zomangamanga
(1) Limbikitsani kumamatira pamwamba pamiyala, onjezerani kusunga madzi, ndikuwonjezera mphamvu ya matope.
(2) Kupititsa patsogolo lubricity ndi pulasitiki, kusintha magwiridwe antchito;gwiritsani ntchito matope opangidwa bwino ndi cellulose ether, omwe ndi osavuta kupanga, amapulumutsa nthawi yomanga ndikuchepetsa ndalama zomanga.
(3) Kusunga madzi owonjezera a cellulose ether kwa njerwa zomayamwa madzi ambiri.
4. Ophatikizana filler
(1) Kusunga madzi kwabwino, nthawi yotseguka yotalikirapo komanso kukonza bwino ntchito.Zamafuta kwambiri komanso zosavuta kusakaniza.(2) Sinthani kukana kwa shrinkage ndi kukana kwa ming'alu ndikuwongolera mawonekedwe apamwamba a zokutira.(3) Sinthani kumamatira kwa malo omangirira kuti mupereke mawonekedwe osalala, osalala.
5. Zomatira za matailosi
(1) Ndikosavuta kuyanika zosakaniza zosakaniza, palibe zopingasa, kukonza liwiro la ntchito, kukonza magwiridwe antchito, kupulumutsa nthawi yogwira ntchito ndikuchepetsa mtengo wantchito.
(2) Kupititsa patsogolo luso la matayala powonjezera nthawi yotsegulira ndikupereka zomatira bwino.
6. Zida zodziyimira pawokha
(1) Amapereka mamasukidwe akayendedwe ndikuchita ngati chithandizo chotsutsa-kukhazikitsa.(2) Limbikitsani kutulutsa kwamadzimadzi ndikuwongolera bwino pakukonza pansi.(3) Kuwongolera kusungidwa kwa madzi ndi kuchepa, kuchepetsa kung'ambika ndi kuchepa pansi.
7. Utoto wamadzi
(1) Imaletsa mvula yolimba ndikutalikitsa nthawi ya chidebe cha chinthucho.High biostability yogwirizana kwambiri ndi zigawo zina.(2) Sinthani madzimadzi, perekani kukana bwino kwa spatter, kukana kwa sag ndikuwongolera kuti muwonetsetse kutha kwapamwamba.
8. Wallpaper ufa
(1) Sungunulani mwachangu popanda zingwe, zomwe ndi zabwino kusakaniza.(2) Perekani mphamvu zomangirira kwambiri.
9. Pepala la simenti yowonjezera
(1) Imakhala ndi mgwirizano wapamwamba komanso wokometsera ndipo imapangitsa kuti zinthu zitheke.(2) Kupititsa patsogolo mphamvu zobiriwira, kulimbikitsa kuchiritsa kwa hydration, ndikuwonjezera zokolola.
10. Mtondo wosakaniza wokonzeka
HPMC mankhwala okonzeka osakaniza matope ndi bwino kuposa mankhwala wamba mu matope okonzeka wothira, kuonetsetsa kuti inorganic cementing zakuthupi mokwanira hydrated, kuteteza kwambiri chomangira mphamvu chifukwa cha kuyanika kwambiri, ndi Crack chifukwa cha kuyanika shrinkage.HPMC ilinso ndi mpweya wina.The HPMC mankhwala kwa premixed matope ali ndi kuchuluka kwa mpweya, yunifolomu ndi thovu ang'onoang'ono, amene angathe kupititsa patsogolo mphamvu ndi kupaka matope okonzeka osakaniza.Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka pamatope osakaniza okonzeka chimakhala ndi vuto linalake, lomwe limatha kuwonjezera nthawi yotsegulira matope okonzeka ndikuchepetsa zovuta zomanga.
