Kugwiritsa ntchito hydroxypropyl methylcellulose mumatope

1. Kusunga madzi

Hydroxypropyl methylcellulose yomanga imalepheretsa chinyezi kulowa khoma.Madzi okwanira amakhala mumtondo, kotero kuti simentiyo imakhala ndi nthawi yayitali yothira madzi.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 njira yofanana ndi yomanga yomanga hydroxypropyl methylcellulose, kuwonjezeka kwa madzi kumatanthauza kuchepa kwa viscosity.Kuwonjezeka kwa kusungidwa kwa madzi kudzawonjezera nthawi yowonjezera ya matope omwe akumangidwa.

2. Kupititsa patsogolo kamangidwe

Kugwiritsiridwa ntchito kwa hydroxypropyl methylcellulose HPMC kumatha kupititsa patsogolo ntchito yomanga matope, kupanga matope kukhala ndi ntchito yabwino yofalitsa, kuchepetsa kumamatira ku zida, kupanga ntchito yomangayo kukhala yosavuta, komanso kuchepetsa mphamvu za ogwira ntchito.

3. Zomwe zili mkati

Kuchuluka kwa kuwira kwa mpweya kumabweretsa kukolola kwamatope komanso kugwira ntchito bwino, kumachepetsa kupangika kwa ming'alu.Zimachepetsanso kuchuluka kwa mphamvu, zomwe zimapangitsa kuti pakhale zochitika za "liquefaction".Kuphulika kwa mpweya nthawi zambiri kumadalira nthawi yogwedeza.Zogulitsa zimagwiritsidwa ntchito kwambiri popititsa patsogolo magwiridwe antchito azinthu zomangira ma hydraulic, monga simenti ndi gypsum.M'matope opangidwa ndi simenti, imathandizira kusunga madzi, imawonjezera kuwongolera ndi nthawi yotseguka, komanso imachepetsa kugwa.

4. Anti-sagging

Mtondo wabwino wosamva fungo umatanthawuza kuti ukagwiritsidwa ntchito mu zigawo zokhuthala palibe vuto lakugwa kapena kutsika.Kukana kwa Sag kumatha kupitilizidwa ndi zomangamanga za hydroxypropyl methylcellulose.Makamaka hydroxypropyl methylcellulose yomwe yangopangidwa kumene yomanga imatha kupereka zinthu zabwino zotsutsana ndi matope.

5. Kunyowetsa luso

Oyenera mapadi etere mankhwala akhoza kusintha mamasukidwe akayendedwe a matope pamene kuonetsetsa ntchito pamwamba ndi chonyowa kumamatira matope, zomwe zimapangitsa matope ndi ntchito bwino kunyowetsa gawo lapansi, ngakhale ntchito EPS kapena XPS, etc. palibe chopiringizika ndi chosanyowetsa chodabwitsa pa maziko apadera.
