I-High Unala Amanzi Ukunciphisa (SMF)yi-anion ephakeme ye-anion ephezulu -polymer. I-SMF ine-adsorption eqinile nethonya elihlukaniswe kuso usimende. I-SMF ingenye yemithombo enhle e-ejenti ekhonkolo ekhona enciphisa. Izici eziphambili yilezi: Amanani amhlophe aphezulu anciphisa, uhlobo lokungenisa olungewona-ke, okuqukethwe okuphansi kwe-chloride ion akubunjiwe emigoqweni yensimbi, nokuvumelana nezimo okuhle ku-chement ehlukahlukene. Ngemuva kokusebenzisa i-ejenti yokunciphisa amanzi, ukuqina kokuqala nokubhebhetheka kokhonkolo kukhule kakhulu, izakhiwo zokwakha nokugcinwa kwamanzi bekungcono, futhi ukugcinwa kwamanzi kwaguqulwa.
Ku-slump kakhonkolo ngokuyisisekelo isimo esifanayo singakwehlisa kakhulu ukuhlanganiswa kwamanzi okuxubana okubizwa ngamanzi aphezulu okunciphisa i-ejenti.Ibheji efanayo kancane kancane
Ukusombulukisa Umlando:Isizukulwane sokuqala sokwenza amanzi aphezulu we-ejenti kanye ne-amentine resin superplasticizer athuthukiswe ekuqaleni kweminyaka yo-1960. Ngenxa yokusebenza kwamanzi ajwayelekile anciphise i-ejenti nge-lignesfonate ethuthukiswe ngasekupheleni kwawo-1930s, kwaziwa nangokuthi i-super spopizer.Ukuhlelwa kwamanzi wesithathu ngemuva kwesizukulwane sesithathu se-superplastimizer - i-polycarboxylic Uchungechunge lwe-Acid. I-contolymer exhubine ne-sulfonic acid kanye ne-carboxylic acid ebaluleke kakhulu esizukulwaneni sesithathu sokunciphisa amandla okunciphisa amanzi, futhi ukusebenza kwawo kubuye kube namanzi aphezulu okunciphisa amanzi anciphisa i-ejenti.
Izinhlobo eziphambili:Amanzi aphezulu anciphisa amandla okunciphisa amanzi angu-ejenti angafinyelela ngaphezu kwama-20%. Ngokwesisekelo se-naphthalene chungechunge, uchungechunge lwe-melamine kanye namanzi anciphisa i-ejenti eyakhiwa ngayo, phakathi kwawo uchungechunge lwe-naphthalalene luyinhloko, kubalwa ngo-67%. Ikakhulu, iningi lama-ejenti amaningi okunciphisa amanzi asuselwa ku-naphthalene njengezinto eziphambili ezingavuthiwe. Ngokuya kokuqukethwe kwe-NA1SO4 e-Naphthalene Series Superplastimizer, kungahlukaniswa ngemikhiqizo ephezulu yokuhlushwa (Okuqukethwe kwe-NA2SO4), imikhiqizo yokuhlushwa ephakathi (NA1SO4 3% -10%) nemikhiqizo yokuhlushwa ephansi (I-NA1SO4> 10% . Most naphthalene superplasticizer synthesis plants have the ability to control the content of Na2SO4 below 3%, and some advanced enterprises can even control the content of NA2SO4 below 0.4%.
Uchungechunge lwe-Naphthalene lokunciphisa amanzi lukhulu kunawo wonke ekukhiqizeni izwe lethu, okusetshenziswa kakhulu kwamanzi okunciphisa amandla (accounting isikhathi esingaphezu kwama-70% inani lokunciphisa amanzi (15% ~ 25%), awukho umoya, umthelela omncane ngesikhathi sokusetha, ukuzivumelanisa nezimo ezinhle kakhulu ngokosisi, kungasetshenziswa nezinye izithasiselo ezahlukahlukene, intengo ishibhile futhi. I-Naphthalene Superplastizer imvamisa isetshenziselwa ukulungiselela ukhonkolo ngokuhamba okuphezulu, amandla aphezulu nokusebenza okuphezulu. Ukulahleka kwe-slump kakhonkolo nge-naphthalene superplastimizer kushesha. Ngaphezu kwalokho, ukuguquguquka kwezimo ze-naphthalene chungechunge lwamanzi anciphisa i-ejenti kanti amanye usimende kufanele athuthukiswe.
Izakhiwo:I-ejenti yokunciphisa amanzi aphezulu inomphumela oqinile wokuhlakazeka ku-usimende, ingathuthukisa kakhulu ukugeleza kwesimende kanye nokhonkolo ukhonkolo, ngenkathi kunciphisa kakhulu ukusetshenziswa kwamanzi, kuthuthukisa kakhulu ukusebenziseka kokhonkolo. Kepha enye i-superplastizer izosheshisa ukulahleka kokhonkolo, ukuxuba okuningi kakhulu kuyophahla amanzi. Ukunciphisa amandla aphezulu okunciphisa i-ejenti empeleni akushintshi isikhathi sokhonkolo, futhi kunomphumela omncane wokubuyisa lapho umthamo ukhulu (ngaphezulu kokufakwa kwamathango), kepha ungakubambezeli ukukhula kokhonkolo okuqinile.
Kunganciphisa kakhulu ukusetshenziswa kwamanzi futhi kuthuthukise kakhulu amandla kakhonkolo ngeminyaka ehlukene. Lapho amandla agcinwa njalo, usimende ungasindiswa ngo-10% noma ngaphezulu.
Okuqukethwe kwe-chloride ion kuncane, akukho mphumela wokugqwala kubha yensimbi. Kungakhulisa ukungavikeleki, ukumelana okuxakile nokumelana nokugqwala kokhonkolo, futhi kuthuthukise ukuqina kokhonkolo.
Isicelo:
1, ilungele zonke izinhlobo zokwakhiwa kwezimboni kanye nokwakhiwa kwamanzi, ukulondolozwa kwamanzi, izinto zokuhamba, i-Port, i-Prepast Perast kanye nokhonkolo oqiniswe endaweni.
2, ilungele amandla aphezulu, amandla aphezulu e-Ultra kanye nokhonkolo wamandla aphakathi, kanye nezidingo zamandla okuqala, ukumelana nesithwathwa esilinganiselwe, ukhonkolo omkhulu we-liquidity.
I-3, ilungele amalungu ekhonkolo e-Precast yenqubo yokuvukela eSteam.
I-4, ilungele ama-admixtures ahlukahlukene ahlukahlukene anciphise amanzi aqinisa amanzi (i-master batch).
