1.Isingeniso somkhiqizo

Uhlobo lwamandla angaphambi kwesikhathi lwePolycarboxylate superplasticizer iyinhlanganisela ye-polycarboxylate superplasticizer ehlanganiswe ne-carboxylic acid ne-ester macromonomers.Amandla okuqala okukhonkolo ahlanganiswe nalo mkhiqizo angathuthukiswa kakhulu, futhi amandla kamuva awanciphi.Ifanele ukhonkolo we-precast kanye nekhonkrithi ehlukahlukene yamandla aphezulu kanye nokusebenza okuphezulu, okunganciphisa isikhathi sokudiliza futhi kuthuthukise ukusebenza kahle kokusebenza kwesikhunta.Lo mkhiqizo unezici ezilandelayo:

(1) Izinga eliphezulu lokuncishiswa kwamanzi, ukuhlakazeka okuhle nomphumela wokugcina ukuhlakazeka kusimende;
(2) Umphumela wangaphambili wokuthuthukisa amandla kakhonkolo uyabonakala, futhi amandla akamuva awanakho ukushwabana;
(3) Okuqukethwe komoya kuphansi, okunciphisa umphumela omubi wamabhamuza omoya kukhonkolo esakhiweni sangaphakathi, futhi kungathuthukisa ukubukeka kokhonkolo ngesikhathi esifanayo;
(4) Ukuzivumelanisa nezimo okuhle kumabanga ahlukahlukene kanye nabakhiqizi abahlukene bakasimende, nokuhambisana okuhle nezixube.

2. Izici Zomkhiqizo

(1) Izinga eliphezulu lokunciphisa amanzi: Lo mkhiqizo unesilinganiso esingu-0.15-0.3% (ngokuya ngokuqukethwe okuqinile) kanye nezinga lokunciphisa amanzi lika-18-40%, elingahlangabezana nezidingo zikasimende wamanzi aphansi kakhulu. isilinganiso kanye nokhonkolo ophezulu we-fluidity.Yonga u-10 kuya ku-20% kasimende.
(2) Ukulahleka kokuwohloka okuphansi: Lo mkhiqizo wethula amaketanga amade aseceleni ama-macromolecules kunqubo yokuhlanganisa, ngakolunye uhlangothi, uvimbela ukugeleza kwamanzi, futhi ngakolunye uhlangothi unikeza isithiyo esiqinile, esingagcina ipulasitiki edakayo isikhathi eside, futhi inokusebenza okuhle.ukugcinwa kwe-slump.
(3) Ukusebenza okuhle kakhulu: Ukhonkolo olungiselelwe ngalo mkhiqizo unokusebenza okuhle, akukho ukuhlukaniswa, akukho delamination, ukuhlangana okuhle, futhi ifanele ukuthuthwa nokumpompa amabanga amade.
(4) Ukuqina okuphezulu: Lo mkhiqizo wenziwa i-polymerized ngesisombululo samanzi se-radical samahhala, esinokuqukethwe kwe-ion ye-chloride encane kakhulu, inani elincane kuphela le-alkali lisetshenziselwa ukwenza i-neutralization, okuqukethwe kwe-alkali kuphansi kakhulu, okuqukethwe kwe-alkali nokuqukethwe kwe-chloride ion kuqhathaniswa uzinzile, futhi i-chlorine ephansi ne-alkali ephansi ingaba enkulu.Ukuthuthukisa ngokuphawulekayo ukuqina kokhonkolo.
(5) I-shrinkage ephansi kanye ne-anti-cracking: Lo mkhiqizo unganciphisa ukushisa kwe-hydration, ubambezele ukuphakama kwe-exothermic, futhi ulungele ukhonkolo wevolumu enkulu, onganciphisa ngempumelelo ukuqhekeka kukakhonkolo okubangelwa umehluko wokushisa we-hydration.
(6) Ukuvikelwa kwemvelo okuluhlaza: Lo mkhiqizo ufakwe i-polymerized nge-free radical aqueous solution.Izinto zokusetshenziswa aziqukethe i-formaldehyde nezinye izinto ezingcolisayo.Akukho ukukhishwa kwendle namanzi angcolile ngesikhathi senqubo yokuhlanganisa, futhi umthwalo wendawo uphansi kakhulu.Iwuhlobo olusha lwezinto zokwakha eziluhlaza futhi ezingasizungezile.
njengolunye uhlobo lwezithako zokunciphisa amanzi asebenza kahle kakhulu,
