- Zomangamanga za Hydroxypropyl methyl cellulose zimagwiritsidwa ntchito kwambiri kupititsa patsogolo magwiridwe antchito a zida zomangira za hydrocoagulant, monga simenti ndi gypsum.M'matope opangidwa ndi simenti, imapangitsa kuti madzi asungidwe bwino, amatalikitsa nthawi yokonza ndi nthawi yotsegula, komanso amachepetsa kutuluka.
- 1. Kusunga madzi
- Kumanga ma cellulose apadera a hydroxypropyl methyl kuti asalowe m'madzi khoma.Madzi oyenerera amakhala mumatope, kotero kuti simenti imakhala ndi nthawi yotalikirapo ya hydration.Kusungidwa kwa madzi ndikofanana ndi kukhuthala kwa cellulose ether solution mumatope.Kuchuluka kwa mamasukidwe amphamvu, kumapangitsa kuti madzi asungidwe bwino.Pamene mamolekyu amadzi akuwonjezeka, kusunga madzi kumachepa.Chifukwa cha kuchuluka komweko kwa nyumba yodzipereka ya hydroxypropyl methyl cellulose, kuchuluka kwa madzi kumatanthauza kuti kukhuthala kumachepa.Kupititsa patsogolo kasungidwe ka madzi kudzapangitsa kuti nthawi yothira matope ionjezeke.
- 2. kukonza zomanga
- Ntchito ya Hydroxypropyl methyl cellulose HPMC imatha kukonza zomangamanga zamatope.
- 3.lubrication luso
- Zinthu zonse zopatsira mpweya zimagwira ntchito ngati zonyowetsa pochepetsa kugwedezeka kwa pamwamba ndikuthandizira ufa wabwino womwe uli mumatope kuti umwazikane ukasakanizidwa ndi madzi.
- 4. Kutsekeka kwa anti-flow -
- Dongo losatha kuyenda bwino limatanthawuza kuti palibe chiwopsezo chakuyenda kolendewera kapena kutsika pansi pogwira ntchito m'magulu okhuthala.Kukana kuyenda kungawongoleredwe pomanga odzipereka a hydroxypropyl methyl cellulose.Makamaka nyumba yomwe yangopangidwa kumene yodzipereka ya hydroxypropyl methyl cellulose imatha kukupatsirani matope kuti azitha kukana.
- 5. Zomwe zili mkati
- Kuchuluka kwa thovu kumapangitsa kuti pakhale zokolola zabwino zamatope komanso kugwira ntchito bwino, kumachepetsa mapangidwe ang'alu.Amachepetsanso mphamvu yamphamvu, "liquefaction" chodabwitsa.Zomwe zimapangidwira nthawi zambiri zimatengera nthawi yoyambitsa.
