Hydroxypropyl methyl cellulose(hpmc)Nthawi zambiri amagwiritsidwa ntchito mu ufa wa putty wokhala ndi mamasukidwe a 100000, pomwe matope amakhala ndi zofunika kwambiri pakuwunikira ndipo ayenera kusankhidwa ndi mamasukidwe akayendedwe a 150000 kuti agwiritse ntchito bwino. Ntchito yofunika kwambiri yahydroxypropyl methyl cellulosendi kusunga madzi, kenako kukhuthala. Choncho, mu ufa wa putty, malinga ngati kusungirako madzi kukufika ndipo kukhuthala kuli kochepa, ndizothekanso. Nthawi zambiri, kukhathamira kwamphamvu kumapangitsa kuti madzi asungidwe bwino. Komabe, pamene mamasukidwe akayendedwe amaposa 100000, zotsatira za mamasukidwe akayendedwe pa kusunga madzi si ofunika.

Jufu Building Material GradeHydroxypropyl Methyl CelluloseKusiyanitsa ndi viscosity, nthawi zambiri imagawidwa m'mitundu iyi:

1. Low mamasukidwe akayendedwe: 400 mamasukidwe akayendedwe mapadi, makamaka ntchito kudzikonda kusanja matope. Low mamasukidwe akayendedwe, flowability wabwino, ndipo pambuyo kuwonjezera, izo kulamulira pamwamba madzi kusunga. Kutuluka kwa magazi sikukuwonekera, kuchepa kwake kumakhala kochepa, ndipo kusweka kumachepa. Ikhozanso kukana kusungunuka, kumapangitsa kuti madzi aziyenda bwino komanso kuti azithamanga.
2. Kukhuthala kwapakati mpaka kutsika: 20000 mpaka 50000 viscosity cellulose, yomwe imagwiritsidwa ntchito makamaka pazinthu za gypsum ndi ma fillers olowa. Kukhuthala kochepa, kusunga bwino madzi, kugwira ntchito bwino, komanso kuwonjezera madzi otsika,
3. Kukhuthala kwapakatikati: 75000-100000 viscosity cellulose, yomwe imagwiritsidwa ntchito kwambiri mkati ndi kunja kwa khoma putty. Kukhuthala pang'ono, kusungika bwino kwa madzi, komanso kamangidwe kabwino kamangidwe.
4. High mamasukidwe akayendedwe: 150000 kuti 200000 yuan, makamaka ntchito polystyrene tinthu kutchinjiriza matope ufa zakuthupi, vitrified yaying'ono mkanda kutchinjiriza matope ndi kukhuthala mkulu ndi posungira madzi. Mtondo si wophweka kugwa ndikupachika, kupititsa patsogolo zomangamanga.
Nthawi zambiri, kukhathamira kwamphamvu kumapangitsa kuti madzi asungidwe bwino. Choncho, makasitomala ambiri amasankha ntchito sing'anga mamasukidwe akayendedwe mapadi (75000-100000) m'malo sing'anga otsika mamasukidwe akayendedwe mapadi mapadi (20000-50000) kuchepetsa kuchuluka kwa Kuwonjezera ndi kulamulira ndalama.
The mamasukidwe akayendedwe aMtengo wa HPMCndi inversely molingana ndi kutentha, mwa kuyankhula kwina, mamasukidwe akayendedwe kumawonjezeka ndi kuchepa kutentha. Kukhuthala kwa mankhwalawa kumatanthauza kuti yankho lake la 2% liri pa kutentha kwa madigiri 20 Celsius, ndipo zotsatira zake ndi zolondola.
M'mapulogalamu apadera, chidwi chiyenera kuperekedwa kumadera omwe ali ndi kusiyana kwakukulu kwa kutentha pakati pa chilimwe ndi nyengo yozizira, ndipo tikulimbikitsidwa kugwiritsa ntchito kukhuthala kochepa m'nyengo yozizira. Apo ayi, ngati mamasukidwe akayendedwe ndi otsika, mamasukidwe akayendedwe a cellulose adzawonjezeka ndipo zokopa zidzakhala zolemetsa.
