Hydroxypropylmethylcellulose HPMC mu pulasitala matope

Hydroxypropyl methylcellulose (HPMC) yopangira matope opaka khoma akunja amapangidwa kuchokera ku thonje la thonje loyera kwambiri kudzera mu etherification yapadera pansi pamikhalidwe yamchere. Ntchito yonseyo imamalizidwa poyang'anitsitsa basi ndipo ilibe zosakaniza zilizonse zanyama. Zosakaniza zogwira ntchito monga ziwalo ndi mafuta. Amagwiritsidwa ntchito kwambiri kukonza zida zomangira ma hydraulic monga simenti ndi gypsum. Mumatope opangidwa ndi simenti, amatha kukonza kusungirako madzi, kutalikitsa nthawi yokonza ndi nthawi yotseguka, ndikuchepetsa kugwa.

Mu pulasitala matope, kuwonjezera kuchuluka kwa hydroxypropyl methylcellulose ndi otsika kwambiri, koma akhoza kwambiri kusintha ntchito ya pulasitala matope, ndipo ndi admixture waukulu umene umakhudza ntchito yomanga matope. Kusankhidwa koyenera kwa hydroxypropyl methylcellulose yokhala ndi ma viscosities osiyanasiyana komanso kuchuluka kwake komwe kumakhala ndi zotsatira zabwino pakuwongolera magwiridwe antchito a matope owuma a ufa.

Populasitala matope, hydroxypropyl methylcellulose HPMC imathandizira kusunga madzi, kukhuthala, kuchedwetsa simenti, komanso kukonza ntchito yomanga.

Kukwanitsa kusunga madzi kumapangitsa kuti simenti ikhale yokwanira, imatha kuwonjezera kukhuthala kwamatope amatope, kumapangitsanso mphamvu yomangira yamatope, komanso kusintha nthawi yogwira ntchito. Kuphatikiza apo, ntchito yopopera yopopera matope imatha kukhala bwino chifukwa chowonjezera hydroxypropyl methylcellulose HPMC, motero hydroxypropyl methylcellulose HPMC idzalimbikitsidwa kwambiri ngati chowonjezera chamatope.

1. Nyumba zosunga madzi - hydroxypropyl methylcellulose HPMC ndi kuteteza madzi kulowa khoma.

Madzi oyenerera amasiyidwa mumatope, zomwe zimapangitsa kuti simenti ikhale ndi nthawi yayitali ya hydration.

Kusungidwa kwa madzi kumagwirizana mwachindunji ndi kukhuthala kwa cellulose ether solution mumatope.

Kuchuluka kwa mamasukidwe amphamvu, kumapangitsa kuti madzi asungidwe bwino. Pamene mamolekyu amadzi akuwonjezeka, kusungirako madzi kudzachepa.

Chifukwa chofanana cha hydroxypropyl methylcellulose HPMC yankho la zomangamanga, kuwonjezeka kwa madzi kumatanthauza kuchepa kwa mamasukidwe akayendedwe.

Kuchuluka kwa kusungirako madzi kumabweretsa nthawi yayitali yochiritsa matope omwe amagwiritsidwa ntchito.

2. HPMC thickener zimagwiritsa ntchito monga thickener mu mawonekedwe wothandizira.

Ikhoza kupititsa patsogolo mphamvu zamakokedwe ndi mphamvu zosunthika, kukonza zokutira pamwamba, kuonjezera zomatira, ndikuwonjezera mphamvu zomatira zamatope.

Kuthekera kwabwino kumapangitsa kuti mawonekedwewo azifanana. Limbikitsani mafuta ndi madzi a matope, pangitsani kukhala kosavuta kugwiritsa ntchito ndikuwongolera magwiridwe antchito.

3. Kugwiritsa ntchito hydroxypropyl methylcellulose HPMC kungathandize kupanga matope.

Guluu wa matailosi atha kugwiritsidwa ntchito ngati chosungira madzi komanso zomatira pakumangirira matailosi, zomwe zitha kupititsa patsogolo ntchito yomanga ya zomatira, kukhala ndi nthawi yayitali yotseguka komanso kumamatira mwamphamvu, ndikuletsa matailosi kuti asagwe mwachangu. .

Zathandizira kusinthika, kusunga bwino madzi, kumamatira kumawonjezera komanso kukana kwamphamvu kwambiri.

Sinthani magwiridwe antchito a matayilo, sinthani magwiridwe antchito a matayilo, onjezerani mphamvu zomangira komanso kumeta ubweya.

4. Lubricate.

Zopangira mpweya zonse zimagwira ntchito ngati chonyowetsa.

Popeza amachepetsa kuthamanga kwapamtunda, amathandizira kufalikira kwa ufa wabwino mumatope akasakaniza ndi madzi.

5. Anti-sag matope amatanthauza kuti palibe chowopsa cha kugwa kapena kugwa pakupanga kosanjikiza.

The sag kukana akhoza bwino ntchito hydroxypropyl methylcellulose HPMC pulasitala matope.

Makamaka hydroxypropyl methylcellulose HPMC yopaka matope ingapereke ntchito yabwino yotsutsa-sag ya matope.
