Ma ether a cellulose amagwiritsidwa ntchito kwambiri ngati zowonjezera mu mortars zopangidwa ndi gypsum kuti awonjezere mawonekedwe osiyanasiyana ndi magwiridwe antchito. Nazi zina mwazomwe zimagwiritsidwa ntchito ndi ma ether a cellulose mu mortars a gypsum:
Kusunga madzi:
Ma cellulose ether ndi ma polima okonda madzi, zomwe zikutanthauza kuti ali ndi mphamvu zambiri pa madzi. Akawonjezeredwa ku mortars a plaster, amasunga chinyezi bwino ndipo amaletsa chisakanizocho kuti chisaume mwachangu. Izi ndizofunikira kuti plaster ikhale ndi nthawi yokwanira yothira madzi bwino ndikuwonjezera kugwira ntchito.
Kusavuta kugwiritsa ntchito komanso kugwiritsa ntchito mosavuta:
Kapangidwe ka madzi ka ma cellulose ethers kumathandiza kuti gypsum mortar igwire bwino ntchito. Mtondo umakhala wosavuta kusakaniza, kufalitsa ndi kugwiritsa ntchito, zomwe zimapangitsa kuti ntchito yomanga ikhale yosalala komanso yogwira mtima.
Kuchepetsa kuchepa kwa thupi:
Ma cellulose ethers amathandiza kuwongolera kuuma kwa gypsum mortars. Mwa kusunga madzi okwanira panthawi yokonza ndi kuumitsa, ma cellulose ethers amathandiza kuchepetsa kusweka kwa ming'alu ndikuwonetsetsa kuti chinthu chomalizidwacho chili chokhazikika.
Konzani kumatirira:
Ma cellulose ethers amathandizira kuti gypsum mortar imamatire ku zinthu zosiyanasiyana, kuphatikizapo makoma ndi denga. Izi ndizofunikira kwambiri pakugwiritsa ntchito monga kupaka pulasitala ndi kukongoletsa, komwe kulumikizana kwamphamvu ndikofunikira kwambiri kuti pamwamba pake pakhale polimba komanso nthawi yayitali.
Kukana ming'alu:
Kuwonjezera ether ya cellulose kungathandize kuti matope asagwedezeke. Izi zimathandiza kwambiri m'malo omwe kayendedwe kake kamatha kuchitika kapena komwe matopewo angakanikizidwe, monga ma joint compound ndi putty layers.
Kuletsa kutsika:
Mu ntchito zoyima, monga ma plaster a pakhoma, ma cellulose ether amagwira ntchito ngati zokhuthala, kuchepetsa kugwa ndi kugwa kwa matope. Izi zimathandiza kusunga makulidwe ofanana pamalo oyima, kukonza kukongola ndi magwiridwe antchito a ntchito yomaliza.
Limbikitsani mgwirizano:
Ma cellulose ether amathandizira kuti chisakanizo cha matope chigwirizane, ndikuwonjezera kulimba kwa kapangidwe kake konse. Izi ndizofunikira kwambiri pakugwiritsa ntchito matope omwe amafunika kupirira mphamvu kapena kupsinjika kwakunja.
Kukhazikika kwa kuzizira ndi kusungunuka:
Ma ether a cellulose amatha kulimbitsa kukhazikika kwa gypsum mortars kuti asaundane ndi kusungunuka, zomwe zimapangitsa kuti asawonongeke kwambiri m'malo omwe kutentha kumasinthasintha. Izi ndizofunikira kwambiri pa ntchito zomanga zomwe zimakumana ndi nyengo yovuta.
Wonjezerani nthawi yokhazikitsa:
Kugwiritsa ntchito ma cellulose ethers kungathandize kukulitsa nthawi yoyika matope a plaster, zomwe zimathandiza kuti ntchito ndi kumaliza zikhale zosavuta kugwiritsa ntchito. Izi zimathandiza makamaka pamene pakufunika maola ambiri ogwirira ntchito.
Kukweza mphamvu za rheological:
Ma cellulose ether amathandizira ku rheological properties a matope, zomwe zimakhudza kayendedwe kake ndi mawonekedwe ake. Izi zimathandiza kukwaniritsa kusinthasintha kofunikira komanso magwiridwe antchito ofunikira.
Ndikofunikira kudziwa kuti mtundu ndi mlingo wa cellulose ether yomwe imagwiritsidwa ntchito komanso kapangidwe ka gypsum mortar ziyenera kuganiziridwa mosamala kuti zikwaniritse zotsatira zomwe mukufuna pakugwiritsa ntchito kwina. Opanga nthawi zambiri amachita mayeso ndi kukonza kuti adziwe kuchuluka kwa cellulose ether komwe kumagwira ntchito bwino pazinthu zawo komanso momwe amagwiritsidwira ntchito.
