Hydroxypropyl methylcellulose popopera mbewu pakhoma!

Zomangamanga za Hydroxypropyl methylcellulose zimagwiritsidwa ntchito kwambiri kupititsa patsogolo magwiridwe antchito azinthu zomangira zama hydraulic, monga simenti ndi gypsum. M'matope opangidwa ndi simenti, imapangitsa kuti madzi asungidwe bwino, amatalikitsa kuwongolera ndi nthawi yotseguka, komanso amachepetsa kugwa.

a. 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 yomanga yomanga hydroxypropyl methylcellulose, kuwonjezeka kwa madzi kumatanthauza kuchepa kwa viscosity. Kuwonjezeka kwa kusungidwa kwa madzi kudzawonjezera nthawi yowonjezera ya matope omwe akumangidwa.

b. Konzani zomangamanga

Kugwiritsa ntchito hydroxypropyl methylcellulose HPMC kumatha kukonza mapangidwe amatope.

c. Lubricate luso

Zopangira mpweya zonse zimagwira ntchito ngati zonyowetsa pochepetsa kugwedezeka kwa pamwamba ndikuthandizira chindapusa cha mumatope kuti chibalalike chikasakanizidwa ndi madzi.

d. 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. Makina omanga enieni a hydroxypropyl methylcellulose opangidwa ndi Shandong Chuangyao Company amatha kupereka zinthu zabwinoko zotsutsana ndi matope.

e. Zolemba za Bubble

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 "liquefaction" chodabwitsa. Kuphulika kwa mpweya nthawi zambiri kumadalira nthawi yogwedeza.

Ubwino wa hydroxypropyl methylcellulose pomanga zinthu zomanga:

Hydroxypropyl methylcellulose ili ndi mawonekedwe ake apadera pakugwiritsa ntchito zida zomangira, kuchokera pakusakanikirana mpaka kubalalitsidwa mpaka kumanga, motere:

Kuphatikizika ndi kasinthidwe:

1. Ndikosavuta kusakaniza ndi ufa wouma wouma.

2. Iwo ali ndi makhalidwe a madzi ozizira kumwazikana.

3. Imitsani tinthu tating'onoting'ono bwino, ndikupangitsa kuti kusakaniza kukhala kosavuta komanso kofanana.

Kubalalitsidwa ndi kusanganikirana:

1. Fomula yowuma yokhala ndi hydroxypropyl methylcellulose imatha kusakanikirana mosavuta ndi madzi.

2. Pezani mwachangu kusinthasintha komwe mukufuna.

3. Kusungunuka kwa cellulose ether kumathamanga komanso popanda zotupa.

Kupanga pa intaneti:

1. Limbikitsani lubricity ndi pulasitiki kuti mupititse patsogolo makina ndikupangitsa kupanga zinthu kukhala kosavuta komanso mwachangu.

2. Limbikitsani mawonekedwe osungira madzi ndikutalikitsa nthawi yogwira ntchito.

3. Imathandiza kupewa kuyenda molunjika kwa matope, matope ndi matailosi. Kutalikitsa nthawi yozizira ndikuwongolera magwiridwe antchito.

Kumaliza ndi mawonekedwe:

1. Limbikitsani mphamvu yomangirira ya zomatira za matailosi.

2. Limbikitsani kuchepa kwa anti-crack ndi mphamvu yolimbana ndi kung'amba kwa matope ndi zomangira za bolodi.

3. Sinthani mpweya mumatope ndikuchepetsa kwambiri kuthekera kwa ming'alu.

4. Sinthani maonekedwe a zinthu zomalizidwa.

5. Ikhoza kupititsa patsogolo kukana kosunthika kwa zomatira za matailosi.

Hydroxypropyl methylcellulose (HPMC) ndi ether yopanda ionic cellulose yopangidwa kuchokera ku thonje loyera kudzera munjira zingapo zamakemikolo. Hydroxypropylmethylcellulose (HPMC) ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni womwe ukhoza kusungunuka m'madzi ozizira kuti ukhale wowonekera bwino wa viscous. Lili ndi katundu wa thickening, kumanga, kubalalika, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba yogwira, kusunga chinyezi ndi kuteteza colloid.
