Njira yochepetsera madzi

Ochepetsa madzi, omwe amadziwikanso kuti mapulasitiki, ndi zowonjezera zomwe zimagwiritsidwa ntchito mu konkriti ndi zinthu zina za simenti kuti achepetse kuchuluka kwa madzi ofunikira kuti akwaniritse ntchito ndi mphamvu zomwe akufuna.Limagwirira wa zochita za ochepetsa madzi akhoza kufotokozedwa ndi zotsatira zake pa thupi katundu cementitious zipangizo.

Zochepetsera madzi zimagwira ntchito potengera tinthu tating'onoting'ono ta simenti ndikusintha ma electrostatic charges pa tinthu ting'onoting'ono.Izi zimachepetsa mphamvu zonyansa pakati pa tinthu tating'onoting'ono, kuwalola kuti azinyamula pamodzi mwamphamvu kwambiri.Zotsatira zake, malo opanda kanthu pakati pa tinthu tating'onoting'ono amachepa, ndipo madzi ofunikira kudzaza malowo amachepa.

Kugwiritsa ntchito zinthu zochepetsera madzi kungathenso kupititsa patsogolo ntchito ya konkire kapena zinthu za simenti, kuti zikhale zosavuta kuzigwira ndi kuziyika.Izi ndichifukwa cha kuchepa kwa mamasukidwe akayendedwe osakaniza, omwe amalola kuyenda bwino ndi kuphatikiza.

Zochepetsa madzi zitha kugawidwa m'magulu awiri: lignosulfonates ndi ma polima opangira.Ma Lignosulfonates amachokera ku zamkati zamatabwa ndipo amagwiritsidwa ntchito kwambiri pa konkriti yamphamvu yotsika mpaka yocheperako.Ma polima a synthetic amapangidwa kuchokera ku mankhwala ndipo amatha kuchepetsa kuchuluka kwa madzi komanso kuwongolera magwiridwe antchito, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito mu konkriti yogwira ntchito kwambiri.

Mwachidule, njira yochitira zinthu zochepetsera madzi imaphatikizapo kulowetsa pa tinthu tating'ono ta simenti ndikusintha ma electrostatic charges pa tinthu ting'onoting'ono.Izi zimachepetsa mphamvu zonyansa pakati pa tinthu tating'onoting'ono ndipo zimawalola kuti azinyamula pamodzi mwamphamvu, kuchepetsa malo opanda kanthu ndi kuchepetsa kuchuluka kwa madzi ofunikira.Kugwiritsa ntchito zinthu zochepetsera madzi kungathenso kupititsa patsogolo ntchito ya konkire kapena zinthu za simenti, kuti zikhale zosavuta kuzigwira ndi kuziyika.
