Kufotokozera mwatsatanetsatane kwa Plaster Retarder

Plaster retarder ndi chowonjezera chomwe chimagwiritsidwa ntchito popaka pulasitala kuti muchepetse nthawi yoyika pulasitala, zomwe zimapangitsa kuti nthawi yogwira ntchito ikhale yotalikirapo komanso kuchepetsa chiopsezo cha kuyanika msanga. Nayi kufotokozera mwatsatanetsatane za pulasitala retarder ndi ntchito yake pulasitala:

1. Ntchito: pulasitala retarder imawonjezeredwa ku zosakaniza za pulasitala kuti ziwonjezere nthawi yoyika pulasitala. Izi zimatalikitsa kugwirira ntchito kwa pulasitala, zomwe zimapangitsa kuti opaka pulasitala azikhala ndi nthawi yambiri yopaka ndikuwongolera zinthuzo zisanayambe kuuma.
2. Kapangidwe kake: Zotsalira za pulasitala zimakhala ndi mankhwala monga lignosulfonates, citric acid, tartaric acid, gluconic acid, kapena organic acids. Mankhwalawa amasokoneza njira ya hydration ya pulasitala, kuchepetsa mapangidwe a gypsum crystals ndikuchedwetsa zomwe zimachitika.
3. Kuwonjeza Nthawi Yogwira Ntchito: Pochepetsa nthawi yoyika pulasitala, obwezeretsa amakulitsa nthawi yogwira ntchito. Izi ndizopindulitsa makamaka pogwira ntchito zazikulu kapena zovuta zopaka pulasitala, pomwe nthawi yayitali yogwira ntchito ndiyofunikira kuti mupeze zotsatira zomwe mukufuna.
4. Kuchepetsa Zinyalala: Pogwiritsa ntchito pulasitala retarder, pulasitala amatha kuchepetsa zinyalala pochepetsa kupezeka kwa pulasitala yomwe imakhazikika mwachangu isanapake bwino. Izi zimathandiza kusunga zinthu ndikuchepetsa kufunika kokonzanso kapena kukonza.
5. Kuwongola Kuwonjezeka: Zolepheretsa pulasitala zimapatsa opaka pulasitala kuwongolera kokulirapo, kuwalola kusintha nthawi yogwirira ntchito ya pulasitalayo kuti igwirizane ndi zomwe polojekiti ikufuna komanso momwe chilengedwe chikuyendera. Kusinthasintha uku kumathandizira kuti ntchito ikhale yolondola kwambiri komanso kumaliza kwabwinoko.
6. Ntchito: Plaster retarder nthawi zambiri amawonjezeredwa kumadzi omwe amagwiritsidwa ntchito kusakaniza pulasitala, potsatira malangizo a wopanga. Ndikofunika kusakaniza retarder bwinobwino ndi madzi musanawonjezere kusakaniza kwa pulasitala kuti mutsimikizire kugawa kofanana ndi kugwira ntchito.
7. Kugwirizana: Zopusitsa zimagwirizana ndi mitundu yosiyanasiyana ya pulasitala, kuphatikizapo gypsum plaster, laimu pulasitala, ndi pulasitala simenti. Komabe, ndikofunikira kusankha choletsa chomwe chili choyenera mtundu wa pulasitala womwe ukugwiritsidwa ntchito ndikutsatira malingaliro a wopanga kuti agwirizane ndi mlingo wake.
8. Zochitika Zachilengedwe: Nthawi yoyika pulasitala imatha kukhudzidwa ndi zinthu zachilengedwe monga kutentha, chinyezi, komanso kuyenda kwa mpweya. M'malo otentha kapena owuma, pulasitala imatha kukhazikika mwachangu, pomwe kuzizira kapena chinyezi, zitha kutenga nthawi kuti ikhazikike. Zotsalira za pulasitala zimathandiza kuchepetsa zotsatira za zinthu zachilengedwezi popereka mphamvu zambiri pakukonzekera.

pulasitala retarder ndi chowonjezera chofunika popaka pulasitala ntchito, kupereka nthawi yotalikirapo ntchito, kuwongolera kuchulukira, ndi kuchepetsa zinyalala. Pochepetsa nthawi yoyika pulasitala, zoletsa pulasitala zimathandiza opaka pulasitala kuti azitha kuchita bwino komanso kuti pulasitala azigwira bwino ntchito, zomwe zimathandizira kuti ntchito yopaka pulasitala ikhale yopambana.
