Polycarboxylic acidzvinoderedza mvura zvinogona kusangana nematambudziko mazhinji mumashandisirwo anoshanda.Zvino ngatitaurei matambudziko akajairika anowanikwa mumainjiniya maapplication uye mhinduro dzawo.
Chekutanga ivhu riri mujecha.Kana madhaka ejecha akakwira, mutero wekudzikisa mutero weiyo polycarboxylic acid inoderedza mvura mumiriririyakaderedzwa zvakanyanya, uye shanduko haisi pachena kana zvirimo zvichiwedzerwa.Mhinduro: Shandisa iyi batch yejecha kune yakaderera-giredhi kongiri yakajairika;nyatso dzora madhaka ejecha uye zvinoda kuti madhaka ave asingasviki 2%.
Yechipiri ndiyo insoluble dambudziko rejecha uyepolycarboxylic acid mvura kuderedza mumiririri.Kana iyo gradation, madhaka emukati, uye madhaka ejecha asangana nezvinodiwa, hainyungudika nepolycarboxylic acid yekudzikisa mvura.Mushonga wemakemikari unopesana nekugadzirwa kwepolycarboxylic acid inoderedza mvura, uye kongiri yakasanganiswa haina fluidity.Mhinduro: Pabheji rega rega rejecha rinopinda panzvimbo, kana zviratidzo zvemuviri zvinokodzera, dzokorora musanganiswa wekongiri yekuvaka kuti ubvise jecha risinganyunguriki kubva panzvimbo.
Zvadaro kongiri inodonha kurasikirwa inokurumidza, iyo inodamugadziri wemvura inoderedza agentkuwedzera slump retention agent, uye wobva washandisa pa-saiti zviwanikwa kuti uite retest yemusanganiswa reshiyo kugadzirisa kurasikirwa kwekudonha kuzadzisa zvinodiwa zvekuvaka.
Chekupedzisira chiitiko chekubuda ropa kwekongiri.Pasi pemvura inonaya, C50 konkrete yakadururwa uye konkrete yakasunungurwa kubva mutangi iri mumamiriro ezvinhu akanaka, asi mushure mokunge kongiri yakazununguswa, kwaiva nekubuda ropa uye kuparadzaniswa.Solution: Deredzai kushandiswa kwemvura, kurebesa kusanganisa nguva, kuderedza 0.1% zvirimo, kongiri vibrating haisi kubuda ropa, uye gadzira zvimisikidzo zvekongiri zvine simba remazuva makumi maviri nemasere rekumanikidza kusvika pakusimba kwekugadzira.
