Zinthu zopanga filimu ndiye chinthu chachikulu chomwe chimakhudza momwe thupi limagwirira ntchito komanso momwe chilengedwe chimagwirira ntchito zokutira matope a diatom.Amagwiritsidwa ntchito ngati filimu yopangira matope a diatom, chophimbacho chimafuna kutsekemera kwa mpweya, mphamvu zomangirira, kukana madzi, kusinthasintha komanso kutsika kwa VOC.Polima akakumana ndi madzi, mamolekyu amadzi amapanga zomangira za haidrojeni ndi -O-, -S-, -N-, ndi zina zotere mu polima, zomwe zimapangitsa kuti chinyezi chizitha kuyamwa.Kuchuluka kwa polarity kwa polima, mphamvu ya mayamwidwe amadzi imakhala yamphamvu, pomwe mphamvu yoyamwa chinyezi ya ma polima omwe si a polar ndi pafupifupi ziro.Mtundu ndi chiwerengero cha magulu a polar pa unyolo wa maselo amatsimikizira mphamvu ya kuyamwa kwa chinyezi;mphamvu ya kuyamwa kwa chinyezi imagwirizananso ndi kapangidwe ka polima.Kuchuluka kwa mamolekyu kumakhala kokhazikika, sikuthandiza kwambiri kuyamwa kwa chinyezi;kachulukidwe filimu adzakhudzanso chinyezi mayamwidwe mphamvu ❖ kuyanika.Kupitilira kwabwinoko, kukulitsa filimuyo, kumapangitsa kuti chinyezi chilowerere;kupitilirabe koyipitsitsa, kulimba kwa capillary kanthu, komwe kumakhala kothandiza kwambiri kuti mamolekyu amadzimadzi alowe.
Udindoszaredispersible latex ufamu matope a diatom:
1. The redispersible latex ufa umapanga filimu pambuyo pobalalitsidwa ndikuchita ngati kulimbikitsa wothandizira ngati chomatira chachiwiri;
2. Colloid yoteteza imatengedwa ndi matope (sidzawonongedwa ndi madzi kapena "obalalika chachiwiri" pambuyo pa kupanga filimu;
3. Ma polima opangidwa ndi filimu amagawidwa mu dongosolo lonse monga kulimbikitsa, potero kumawonjezera mgwirizano;redispersible latex ufandi azomatira ufazopangidwa kuchokera ku emulsion yapadera (polymer) yowumitsidwa .Ufawu ukhoza kubwezeretsedwanso mwamsanga kuti upangitse emulsion pambuyo pa kukhudzana ndi madzi, ndipo uli ndi zinthu zomwezo monga emulsion yoyamba, ndiko kuti, ikhoza kupanga filimu madzi atatha.Kanemayu ali ndi kusinthasintha kwakukulu, kukana kwanyengo komanso kugonjetsedwa ndi zosiyanasiyanahigh kumamatira ku gawo lapansi.
4. Monga organic gelling material, ufa wapadera wa latex wa matope a diatom ukhoza kupititsa patsogolo kumamatira kwa zida zapakhoma za matope a diatom, kuwonjezera kusinthasintha, kuchepetsa kusweka, ndi kuonjezera mgwirizano.
The Special redispersiblelatexufa wa matope a diatom uyenera kukhala wopanda fungo, kukulitsa mphamvu yolumikizana pakati pa matope a diatom ndi gawo loyambira, kuwongolera kulumikizana kwake, kuwongolera kutentha kwake ndi kukana chinyezi, ndikupanga matope a diatom kukhala ndi kusinthasintha kwina kuti ateteze mawonekedwe osiyanasiyana.kusweka, pomwe sikumakhudza kutsatsa komanso kuwongolera chinyezi chamatope a diatom.
