Ma cellulose ether amatha kusintha kwambiri magwiridwe antchito a matope onyowa, ndipo ndi chowonjezera chachikulu chomwe chimakhudza ntchito yomanga matope. Kusankhidwa koyenera kwa ma cellulose ethers amitundu yosiyanasiyana, ma viscosity osiyanasiyana, makulidwe osiyanasiyana a tinthu, magawo osiyanasiyana a mamasukidwe akayendedwe ndi kuchuluka kowonjezera kudzakhala ndi zotsatira zabwino pakuchita bwino kwa matope owuma a ufa.
Palinso ubale wabwino wa mzere pakati pa kusasinthika kwa phala la simenti ndi mlingo wa cellulose ether. Selulosi ether akhoza kwambiri kuonjezera mamasukidwe akayendedwe a matope. Mlingo waukulu kwambiri, zotsatira zake zimakhala zoonekeratu. High-viscosity cellulose ether amadzimadzi njira ali mkulu thixotropy, amenenso ndi khalidwe lalikulu la mapadi ether.
The thickening zotsatira zimadalira mlingo wa polymerization wa mapadi efa, njira ndende, kukameta ubweya mlingo, kutentha ndi zina. Katundu wa gelling wa yankho ndi wapadera kwa alkyl cellulose ndi zotuluka zake zosinthidwa. Makhalidwe a gelation amakhudzana ndi kuchuluka kwa m'malo, ndende ya yankho ndi zowonjezera. Kwa zotumphukira zosinthidwa za hydroxyalkyl, mawonekedwe a gel amalumikizananso ndi digiri yosinthidwa ya hydroxyalkyl. 10% -15% yankho akhoza kukonzekera otsika mamasukidwe akayendedwe MC ndi HPMC, 5% -10% yankho akhoza kukonzekera sing'anga mamasukidwe akayendedwe MC ndi HPMC, ndi 2% -3% yankho akhoza kukonzekera mkulu-kukhuthala MC ndi HPMC. Nthawi zambiri kukhuthala kwa makulidwe a cellulose ether kumayikidwanso ndi 1% -2% yankho.
Maselo a cellulose ether ali ndi mphamvu zambiri zokhuthala. Ma polima okhala ndi zolemetsa zosiyanasiyana zama cell amakhala ndi ma viscosity osiyanasiyana munjira yofananira. Madigiri apamwamba. Chandamale mamasukidwe akayendedwe angapezeke kokha ndi kuwonjezera kuchuluka otsika maselo kulemera cellulose ether. Kukhuthala kwake kumadalira pang'ono kumeta ubweya wa ubweya, ndipo kukhuthala kwapamwamba kumafika kukhuthala kwa chandamale, ndipo kuchuluka komwe kumafunikira kumakhala kochepa, ndipo kukhuthala kumadalira kukhuthala kwamphamvu. Choncho, kuti akwaniritse kusasinthasintha kwina, kuchuluka kwa cellulose ether (kukhazikika kwa yankho) ndi kukhuthala kwa yankho ziyenera kutsimikiziridwa. Kutentha kwa gel osakaniza kumachepetsanso mofanana ndi kuwonjezeka kwa ndende ya yankho, ndi gel osakaniza kutentha kwa firiji atatha kufika pamtundu wina. The gelling ndende ya HPMC ndi mkulu kutentha firiji.
