Mumatope osakaniza okonzeka, kuwonjezera kwa cellulose ether kumakhala kotsika kwambiri, koma kungathe kusintha kwambiri ntchito ya matope onyowa, omwe ndi chowonjezera chachikulu chomwe chimakhudza ntchito yomanga matope.ntchito yofunika ya HPMC mu matope makamaka mbali zitatu, imodzi ndi yabwino kwambiri madzi posungira mphamvu, chachiwiri ndi zotsatira pa matope kusasinthasintha, ndipo chachitatu ndi kugwirizana ndi simenti.
1. Kuchuluka kwa kukhuthala kwa cellulose ether, kumapangitsa kuti madzi asungidwe bwino.
2. Kuchulukirachulukira kwa cellulose ether mumatope, kumapangitsa kuti madzi asungidwe bwino.
3. Pa kukula kwa tinthu, tinthu tating'onoting'ono timakhala bwino ndi kusunga madzi.
4. Kusungidwa kwa madzi kwa methyl cellulose ether kumachepa ndi kuwonjezeka kwa kutentha.
Kukhuthala kwa hydroxypropyl methyl cellulose ngati thickener kumakhudzana ndi kukula kwa tinthu, mamasukidwe akayendedwe ndi kusinthidwa kwa hydroxypropyl methyl cellulose.Nthawi zambiri, kukwezeka kwa kukhuthala kwa cellulose ether, kumachepetsa kukula kwa tinthu, m'pamenenso zimawonekera kwambiri.
Ntchito yachitatu ya ma cellulose ethers ndikuchepetsa kutulutsa kwa simenti.Ma cellulose ether amapatsa matope zinthu zopindulitsa zosiyanasiyana komanso amachepetsa kutentha kwa simenti koyambirira komanso kulepheretsa mphamvu ya simenti.Kuchulukirachulukira kwa cellulose ether mu mineral gel zakuthupi, m'pamenenso zimawonekera kwambiri kuchedwa kwa hydration.Ma cellulose ether samangochedwetsa makonzedwe, komanso amachedwetsa kuuma kwa machitidwe amatope a simenti.Ndi kuwonjezeka kwa mlingo wa HPMC, nthawi yoyika matope inakula kwambiri.
Mwachidule, mumatope osakaniza okonzeka, HPMC imagwira ntchito yosungira madzi, kukulitsa, kuchedwetsa mphamvu ya simenti ya hydration ndikuwongolera ntchito yomanga.Kutha kwabwino kusunga madzi kumapangitsa kuti simenti ikhale yokwanira, yomwe imatha kupititsa patsogolo kumamatira konyowa kwamatope ndikuwonjezera mphamvu yomangira matope.Chifukwa chake, HPMC ikugwiritsidwa ntchito kwambiri ngati chowonjezera chofunikira mumatope osakaniza okonzeka.
