Hydroxypylropyl (hpmc) ndi hydroxyethyl cellulose (hec) nthawi zambiri amagwiritsidwa ntchito pomanga zida chifukwa cha ntchito zawo zoyenera ndi katundu. Nayi zina mwazinthu zazikulu zomangira zomanga:

1. Kusunga kwamadzi: HPMC ndi HeC ndi Hec monga posunga madzi, kuthandizira kupewa madzi am'madzi mwachangu kuchokera pazopangidwa ndi simenti ndi dothi ndi pulasitala pochiritsa. Mwa kupanga kanema kuzungulira tinthu tambiri, amachepetsa madzi, kulola kuti kwa nthawi yayitali komanso yotukuka.
2. Kupititsa patsogolo: HPMC ndi Hec moyenera kugwiritsidwa ntchito kwazinthu za simenti powonjezera ma pulasitiki awo ndikumachepetsa mikangano pakati pa tinthu. Izi zimathandizira kufalikira, kusamatira, komanso kumasuka ku mativa, omata, ndi ma tile, ndi ma yunifolomu yomaliza komanso yolunjika.
3. Kuwongolera ndi Rhelogy: HPMC ndi Hec ntchito ngati thikhiniya ndi rheology zosinthira zomangira, zimasintha ma viwa awo komanso mawonekedwe oyenda. Amathandizira kupewa kusuntha ndi tsankho la zosakaniza zoyikika, kuonetsetsa kugawa kokhazikika komanso kusakhazikika.
4. Kukweza Kwa Adesion: HPMC ndi Hec kukonza chitseko cha zinthu za simenti, zochokera ku konkriti, zomanga, ndi matailosi. Mwa kupanga kanema woonda pamtunda wa gawo lapansi, amalimbikitsa mphamvu ya matope ndi kukhazikika kwa maboti, zomata, ndi tile pa chiopsezo cha kuchepetsedwa kapena kulephera.
5. Kutsitsa kwa Shrinka: HPMC ndi HeC Kuthandizidwa kuti muchepetse zinthu zazing'onoting'ono ndikusintha zida zawo ndikuwongolera zipsinjo zawo. Amakwaniritsa izi pokulitsa tinthu tating'onoting'ono, zimachepetsa kuchepa kwa madzi, komanso kuwongolera kuchuluka kwa mankhwala, zomwe zimapangitsa kuti zikhale zolimba komanso zosangalatsa.
6. Kukhazikitsa Nthawi Kulamulira: HPMC ndi Hec ikhoza kugwiritsidwa ntchito kusintha makonzedwe a zinthu za simenti posintha mlingo ndi kunenepa. Amapereka kusinthasintha pokonza zomangamanga ndikulola kuwongolera bwino panjirayo, malo ogwiritsira ntchito polojekiti yosiyanasiyana ndi nyengo.
7. Kukhazikika kwabwino: HPMC ndi Hec zimathandizira kuti zikhale zolimbitsa thupi polimbikitsa kukana kwawo kwa zinthu zachilengedwe monga manyowa, ndi kuwukira kwa mankhwala. Amathandizira kuchepetsa kusokonekera, kukhazikika, ndi kuwonongeka, ndikupereka moyo wa ntchito zomanga.

Hydroxypropyl methylcellulose (hpmc) ndi hydroxyethyl cellulose (hec) amasewera maudindo omwe amagwira ntchitoyo, kugwirira ntchito, zomatira, kukhazikika kwa zinthu zomanga. Malo awo osiyanasiyana amawapangitsa kukhala owonjezera owonjezera m'mapulogalamu osiyanasiyana, kuonetsetsa kupambana ndi kukhazikika kwa ntchito zomanga zosiyanasiyana.
