HPMC ntchito muzomangamanga

Hydroxypropyl methylcellulose (HPMC)ndi non-ionic cellulose ether yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera mumndandanda wamankhwala. Ndi ufa woyera wopanda fungo, wosakoma komanso wopanda poizoni womwe umatuluka m'madzi ozizira mpaka kumadzi owoneka bwino kapena owunda pang'ono. Ali ndi katundu wa thickening, kumanga, kubalalitsa, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba katundu, kusunga chinyezi ndi zoteteza colloids. Hydroxypropyl methylcellulose, methylcellulose angagwiritsidwe ntchito zomangira, makampani ❖ kuyanika, kupanga utomoni, zoumba mafakitale, mankhwala, chakudya, nsalu, ulimi, tsiku mankhwala ndi mafakitale ena.

Kugwiritsa ntchito kwakukulu kwa hydroxypropyl methylcellulose HPMC muzomangamanga:

1 chikho chopangidwa ndi simenti

①Sinthani kufanana, pangani pulasitala kuti ikhale yosavuta kugwedezeka, sinthani kukana kwa sag, onjezerani madzimadzi komanso pompopompo, ndikuwongolera magwiridwe antchito.

②Kusunga madzi ambiri, kutalikitsa nthawi yoyika matope, kuwongolera magwiridwe antchito, komanso kuwongolera kuyatsa ndi kulimba kwa matope kuti apange mphamvu zamakina apamwamba.

③ Yang'anirani kuyambitsa kwa mpweya kuti muchotse ming'alu pamwamba pa zokutira ndikupanga malo abwino osalala.

2 Zopaka pulasitala zopangidwa ndi gypsum ndi zinthu za gypsum

①Sinthani kufanana, pangani pulasitala kuti ikhale yosavuta kugwedezeka, sinthani kukana kwa sag, onjezerani madzimadzi komanso pompopompo, ndikuwongolera magwiridwe antchito.

②Kusunga madzi ambiri, kutalikitsa nthawi yoyika matope, kuwongolera magwiridwe antchito, komanso kuwongolera kuyatsa ndi kulimba kwa matope kuti apange mphamvu zamakina apamwamba.

③ Yang'anirani kusasinthasintha kwa matope kuti akhale ofanana ndikupanga zokutira koyenera pamwamba.

3 Mtondo wamiyala

① Limbikitsani kumamatira ndi pamwamba pamiyala, onjezerani kusunga madzi, ndikuwonjezera mphamvu ya matope.

②Kupititsa patsogolo lubricity ndi pulasitiki, ndikuwongolera magwiridwe antchito; matope opangidwa bwino ndi cellulose ether ndi osavuta kupanga, amapulumutsa nthawi yomanga ndikuchepetsa mtengo womanga.

③Ultra-high-water-retaining cellulose ether, yoyenera ku njerwa zomangira madzi.
4 mbale joint filler

①Kusunga madzi kwabwino, kukulitsa nthawi yotsegula ndikuwongolera magwiridwe antchito. Mafuta okwera, osavuta kusakaniza.

②Kupititsa patsogolo kukana kwa shrinkage ndi kukana kwa ming'alu, ndikuwongolera mawonekedwe apamwamba a zokutira.

③ Sinthani kumamatira kwa malo omangirira ndikupereka mawonekedwe osalala komanso osalala.

5 Zomatira za matailosi

①Zosakaniza zosakaniza zowuma zowuma, palibe zotupa zomwe zingapangidwe, kuthamanga kwa ntchito kudzachulukidwa, ntchito yomangayo idzawongoleredwa, nthawi yogwira ntchito idzapulumutsidwa, ndipo mtengo wogwirira ntchito udzachepetsedwa.

②Powonjezera nthawi yotsegulira, imapangitsa kuti matayala azitha kugwira ntchito bwino komanso amamatira kwambiri.

6 Zida zodziikira zokha pansi

① Amapereka mamasukidwe akayendedwe ndipo atha kugwiritsidwa ntchito ngati chithandizo chotsutsa-kukhazikitsa.

②Kupititsa patsogolo kutulutsa kwamadzimadzi ndikuwongolera kuyendetsa bwino kwapaving.

③ Yang'anirani kusungidwa kwa madzi ndi kuchepa kuti muchepetse ming'alu ndi kuchepera kwa nthaka.

7 Utoto wotengera madzi

① Pewani mvula yolimba ndikutalikitsa nthawi yotengera zinthu. Kukhazikika kwachilengedwe kwapamwamba komanso kuyanjana kwabwino ndi zigawo zina.

②Sinthani madzimadzi, perekani kukana bwino kwa splash, kukana kwa sag ndi kusanja, ndikuwonetsetsa kuti kutha kwapamwamba kwambiri.

8 wallpaper ufa

① Sungunulani mwachangu popanda kuphatikiza, komwe ndikosavuta kusakanikirana.

②Patsani mphamvu zomangira zolimba kwambiri.

9 Bolodi la simenti yowonjezera

①Ili ndi zomatira kwambiri komanso zokometsera, ndipo imathandizira kuti zinthu zomwe zatulutsidwa zitheke.

②Kupititsa patsogolo mphamvu zobiriwira, kulimbikitsa ma hydration ndi machiritso, ndikuwonjezera zokolola.

Zinthu 10 za HPMC zamatope osakaniza okonzeka

TheMtengo wa HPMCChopangidwa chomwe chimagwiritsidwa ntchito ngati matope osakanikirana chimakhala ndi madzi osungira bwino kuposa zinthu wamba mumtondo wosakanikirana, kuonetsetsa kuti zinthu za cementitious zakuthupi zili ndi hydrated, ndikuletsa kwambiri kuchepa kwa mphamvu zomangira zomwe zimayambitsidwa ndi kuyanika kwakukulu ndi kusweka komwe kumachitika chifukwa chowumitsa shrinkage. HPMC imakhalanso ndi mphamvu yolowetsa mpweya. Zogulitsa za HPMC zomwe zimagwiritsidwa ntchito makamaka pamatope okonzeka osakaniza zimakhala ndi zoyenerera, yunifolomu komanso mpweya wochepa, womwe ukhoza kupititsa patsogolo mphamvu ndi pulasitala wamatope 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 mumndandanda wamankhwala. Ndi ufa woyera wopanda fungo, wosakoma komanso wopanda poizoni womwe umatuluka m'madzi ozizira mpaka kumadzi owoneka bwino kapena owunda pang'ono. Ali ndi katundu wa thickening, kumanga, kubalalitsa, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba katundu, kusunga chinyezi ndi zoteteza colloids. Hydroxypropyl methylcellulose, methylcellulose angagwiritsidwe ntchito zomangira, makampani ❖ kuyanika, kupanga utomoni, zoumba mafakitale, mankhwala, chakudya, nsalu, ulimi, tsiku mankhwala ndi mafakitale ena.
