Mafakitale hydroxypropyl methylcellulose omwe amagwiritsidwa ntchito ngati matope (apa akutanthauza mapadi oyera, osaphatikiza zinthu zosinthidwa) amasiyanitsidwa ndi mamasukidwe akayendedwe, ndipo magiredi otsatirawa amagwiritsidwa ntchito kwambiri (gawoli ndi mamasukidwe akayendedwe):
Low mamasukidwe akayendedwe: 400
Amagwiritsidwa ntchito makamaka ngati matope odzipangira okha;mamasukidwe akayendedwe ndi otsika, ngakhale kusunga madzi ndi osauka, koma kusanja katundu ndi zabwino, ndipo kachulukidwe matope ndi mkulu.
Kukhuthala kwapakati ndi otsika: 20000-40000
Amagwiritsidwa ntchito makamaka zomatira matailosi, ma caulking agents, matope odana ndi ming'alu, matope omangira matenthedwe, ndi zina zambiri;yomanga bwino, madzi ochepa, kachulukidwe kamatope ambiri.
Kukhuthala kwapakatikati: 75000-100000
Amagwiritsidwa ntchito makamaka pa putty;kusunga bwino madzi.
Kuthamanga kwakukulu: 150000-200000
Iwo makamaka ntchito polystyrene tinthu matenthedwe kutchinjiriza matope mphira ufa ndi vitrified microbead matenthedwe kutchinjiriza matope;mamasukidwe akayendedwe ndi mkulu, matope si kophweka kugwa, ndi kumanga bwino.
Muzochita zothandiza, ziyenera kuzindikiridwa kuti m'madera omwe ali ndi kusiyana kwakukulu kwa kutentha pakati pa chilimwe ndi chisanu, tikulimbikitsidwa kugwiritsa ntchito kukhuthala kochepa kwambiri m'nyengo yozizira, yomwe imakhala yabwino kwambiri pomanga.Apo ayi, kutentha kukakhala kochepa, kukhuthala kwa cellulose kumawonjezeka, ndipo dzanja limakhala lolemera pamene likukanda.
Nthawi zambiri, kukhathamira kwamphamvu kumapangitsa kuti madzi asungidwe bwino.Poganizira za mtengowo, mafakitale ambiri owuma a ufa amalowa m'malo mwa sing'anga ndi otsika mamasukidwe a cellulose (20000-40000) ndi cellulose yapakatikati (75000-100000) kuti achepetse kuchuluka.Zogulitsa zamatope ziyenera kusankhidwa kuchokera kwa opanga nthawi zonse ndikuzindikiridwa.
Ubale pakati pa mamasukidwe akayendedwe ndi kutentha kwa HPMC:
The mamasukidwe akayendedwe a HPMC ndi inversely proportional kutentha, ndiko kuti, mamasukidwe akayendedwe ukuwonjezeka pamene kutentha amachepetsa.Kukhuthala kwa chinthu chomwe timakonda kunena kumatanthawuza zotsatira za mayeso a 2% yankho lamadzi pa kutentha kwa madigiri 20 Celsius.
