Mawonekedwe a ma viru ndi gawo lofunikira la cellulose ether.
Nthawi zambiri, mafayilo apamwamba, abwinobwino amadzisungira madzi a gypsum. Komabe, ma virus, okwera maselo olemera a cellulose ether, ndipo kutsika kolingana kofananira mu kusungunuka kwake kumabweretsa zovuta pa mphamvu ndi matope omanga matope. Maonekedwe ake, zoonekeratu kuti zimakula kwambiri patavala matope, koma siyofanana mwachindunji.
Matope apamwamba, matope owoneka bwino adzakhala. Panthawi yomanga, imawonekera ngati imamatira ku starpiper ndi kutsatira kwambiri mpaka gawo lapansi. Koma sizothandiza kukulitsa mphamvu ya matonthozo onyowa. Kuphatikiza apo, pomanga, magwiridwe antchito a Anti-sag okhala ndi matope onyowa sizachidziwikire. M'malo mwake, sing'anga zina zapakati komanso zochepa koma kusinthidwa methyl cellose celluse kukhala ndi ntchito yabwino kwambiri pokonzanso mphamvu ya matope onyowa.
Kumanga zida za khoma ndi zomangamanga kwambiri, ndipo onse amakhala ndi mayamwidwe amadzi olimba. Komabe, zinthu zomangamanga zama Gypsum zomwe zimagwiritsidwa ntchito pomanga khoma zimakonzedwa ndikuwonjezera madzi kukhoma, ndipo madziwo amatengedwa mosavuta khomalo, zomwe zimapangitsa kuti ntchito yomanga gypsum ikhale yopanga ndikuchepetsa Mphamvu zolimba, zomwe zimabweretsa ming'alu, zovuta zapamwamba monga zosakira ndi kusambira. Kuwongolera kusungidwa kwamadzi kwa zida zomangira gypsum kumatha kusintha mtundu wa zomangamanga ndi gulu lolumikizirana ndi khoma. Chifukwa chake, wothandizira madzi osunga madzi tsopano wakhala imodzi mwazoloweza zoyeserera za gypsum.
Kupaka gypsum, gypsum gypsum, gypsum gypsum, gypsum putty ndi zida zina zomanga zimagwiritsidwa ntchito. Pofuna kuwongolera zomangamanga, ogula gypsum amawonjezeredwa pakupanga nthawi yomanga yomanga kwa gypsum slorry. Chifukwa gypsum imasakanikirana ndi yopumira, yomwe imaletsa njira ya hemihydrate gypsum. Mtundu wamtunduwu wa gypsum slurry akuyenera kusungidwa kukhoma kwa maola 1 mpaka 2 asanakhazikitse. Ambiri mwa makoma amakhala ndi mayamwidwe amadzi, makamaka makoma a njerwa ndi konkriti. Khoma, bolodi yotchinga ndi zida zina zam'manja zatsopano, chifukwa chake chithandizo chosungiramo madzi chiyenera kuchitika Kusalala kumawuma. Pangitsa kupatukana ndi kusenda kwa cholumikizira pakati pa gypsum ndi khoma. Kuphatikiza kwa wothandizila kwa madzi ndikusunga chinyezi chokhala ndi gypsum slurry, kuonetsetsa kuti ma hydram omwe amasankha gypsum pa mawonekedwe, kuti atsimikizire kuti pali mphamvu. Othandizira osungidwa m'madzi omwe amakhala ndi cellouse, monga: Methyl cellulose (hertroxypyl (heldrox), sodium yosinthika, Zochitika zapadziko lapansi, etc. zitha kugwiritsidwanso ntchito kukonza magwiridwe antchito.
