Umthamo kanye nokusetshenziswa kwamanzi kwePolycarboxylate Superplastimizer:

Polycarboxylate superplastimizerinezimpawu zemithamo ephansi kanye nokwehliswa kwamanzi okuphezulu. Lapho umthamo u-0,15-0.3%, izinga lokunciphisa amanzi lingafinyelela ku-18-40%. Kodwa-ke, lapho isilinganiso samanzi-esiya e-mbinder sincane (ngezansi kuka-0.4), umthamo uzwela kakhulu kunalapho isilinganiso samanzi esiphezulu. Izinga lokunciphisa amanzipolycarboxylate superplastimizerkuyehluka ngenani le-cemential impahla. Ngaphansi kwezimo ezifanayo, izinga elincishisiwe lamanzi lenani lezinto eziqinisekisiwe ezingaphansi kwama-3 lingaphansi kwama-400kg / m3, futhi lo mehluko unganakwa kalula. Kodwa-ke, kwinqubo yokusebenzisa, izotholakala ukuthi le ndlela yendabuko yendabuko ayilungelePolycarboxylate superplastimizer, ikakhulukazi ngobaPolycarboxylate superplastimizerzizwela kakhulu ukusetshenziswa kwamanzi kunezimpawu zendabuko zendabuko. Lapho ukusetshenziswa kwamanzi kuncishiswa, ukusebenziseka okulindelekile kokhonkolo ngeke kufinyelelwe; Lapho ukusetshenziswa kwamanzi kuphezulu, yize ukuncibilika kukhula, kuzoba nokopha okuningi ngisho nokuhlukaniswa okuncane, okunomthelela ongemuhle ekusebenzeni kokhonkolo. Lokhu kuzodala ukuphazamiseka okuningi ekwakhiweni kwangempela kwesiza. Izinga lokushisa linethonya elihle ngenani lepolycarboxylate superplastimizer. Empeleni, kutholakala ukuthi inani lokuhlanganiswa elisetshenziswe ekukhiqizweni okujwayelekile phakathi nosuku liphansi ebusuku (izinga lokushisa liphansi kune-15 ℃), futhi ukushiswa kuvame ukwenzeka "ukubuyela kokukhulu", ngisho nokuhlukaniswa nokuhlukaniswa.

Ukhonkolo ukhethe kakhulu ngephuzu le-satunation kanye nokusetshenziswa kwamanzi okunciphisa i-ejenti. Lapho inani elidlulele selidluliwe, ukhonkolo kuzovela izehlakalo ezingezinhle njengokuhlukaniswa, ukopha, ukugijima okugijimayo, ukuqina nokuqukethwe komoya ngokweqile.

(1) Ukuhlolwa kokuhlanganiswa kwecala kufanele kwenziwe futhi ngezinto zokwakha ezishintshiwe zokuguqula umthamo ukuze uzuze umphumela omuhle kakhulu;

(2) umthamo wepolycarboxylate superplastimizerfuthi ukusetshenziswa kwamanzi ngokhonkolo kufanele kulawulwe ngokuqinile ngesikhathi sokusetshenziswa;
