I-High RANGE WATER REDUCER(SMF)iyi-anion encibilikayo emanzini ephezulu -polymer medium kagesi.I-SMF ine-adsorption eqinile kanye nomphumela wokusabalalisa kusimende.I-SMF ingelinye lama-schizes wemithombo e-ejenti ekhona yokunciphisa amanzi kakhonkolo.Izici eziyinhloko yilezi: okumhlophe, izinga eliphezulu lokunciphisa amanzi, uhlobo lwe-non-air induction, okuqukethwe kwe-ion ye-chloride ephansi akugqwalile emigodleni yensimbi, kanye nokuvumelana nezimo ezinhle kusimende ehlukahlukene.Ngemuva kokusebenzisa i-ejenti yokunciphisa amanzi, ukuqina kokuqala kanye nokuqina kwekhonkrithi kwanda kakhulu, izakhiwo zokwakha kanye nokugcinwa kwamanzi kwakungcono, futhi ukulungiswa kwe-steam kwashintshwa.
In the slump ukhonkolo ngokuyisisekelo isimo esifanayo kunganciphisa kakhulu ukuxubana amanzi admixture ngokuthi high ukusebenza kahle amanzi reduction agent.Endabeni efanayo efanayo ukuwohloka ukhonkolo efanayo, ukuxuba kanye ukusetshenziswa kwamanzi kungancishiswa ezingaphezu kuka-15%.
Intuthuko umlando:Isizukulwane sokuqala se-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-amine resin-based superplasticizer yasungulwa ekuqaleni kwawo-1960.Ngenxa yokusebenza kwe-ejenti evamile yokunciphisa amanzi nge-lignesulfonate eyakhiwa ngasekupheleni kwawo-1930, yaziwa nangokuthi i-super plasticizer.I-ejenti yokunciphisa amanzi yesizukulwane sesibili i-amino sulfonate, nakuba ngokulandelana kwesikhathi ngemva kwesizukulwane sesithathu se-superplasticizer - polycarboxylic. uchungechunge lwe-asidi.I-graft copolymer ene-sulfonic acid ne-carboxylic acid ibaluleke kakhulu esizukulwaneni sesithathu se-ejenti yokunciphisa amanzi ephumelela kakhulu, futhi ukusebenza kwayo futhi kuyi-ejenti yokunciphisa amanzi esebenza kahle kakhulu.
Izinhlobo eziyinhloko:Izinga lokunciphisa amanzi elisebenza kahle kakhulu lingafinyelela ngaphezu kwama-20%.Ngokuyinhloko uchungechunge lwe-naphthalene, uchungechunge lwe-melamine kanye ne-ejenti yokunciphisa amanzi eyakhiwe ngazo, phakathi kwazo uchungechunge lwe-naphthalene oluyinhloko, olubalelwa ku-67%.Ikakhulukazi, iningi lama-ejenti okunciphisa amanzi asebenza kahle kakhulu asekelwe ku-naphthalene njengento eyinhloko eluhlaza.Ngokusho kokuqukethwe kwe-Na2SO4 ochungechungeni lwe-naphthalene superplasticizer, ingahlukaniswa ngemikhiqizo yokuhlushwa ephezulu (okuqukethwe kwe-Na2SO4 <3%), imikhiqizo yokuhlushwa okuphakathi (okuqukethwe kwe-Na2SO4 3% -10%) kanye nemikhiqizo yokuhlushwa ephansi (okuqukethwe kwe-Na2SO4> 10%) .Izitshalo eziningi ze-naphthalene superplasticizer synthesis zinamandla okulawula okuqukethwe kwe-Na2SO4 ngaphansi kuka-3%, futhi amanye amabhizinisi athuthukile angakwazi ukulawula okuqukethwe kwe-NA2SO4 ngaphansi kuka-0.4%.
I-Naphthalene uchungechunge lwe-ejenti yokunciphisa amanzi iyona enkulu kunazo zonke emkhiqizweni wezwe lethu, i-ejenti yokunciphisa amanzi esetshenziswa kakhulu esebenza kahle kakhulu (ebala ngaphezu kuka-70% yenani le-ejenti yokunciphisa amanzi), ebonakala ngezinga eliphezulu lokunciphisa amanzi (15% ~ 25%), akukho moya, umphumela omncane ngesikhathi sokumisa, ukuguquguquka okuhle ngosimende, kungasetshenziswa nezinye izithasiselo ezahlukahlukene, intengo nayo ishibhile.I-Naphthalene superplasticizer ivame ukusetshenziselwa ukulungisa ukhonkolo ngokuhamba okuphezulu, amandla aphezulu nokusebenza okuphezulu.Ukulahleka kokuwohloka kukakhonkolo nge-naphthalene superplasticizer kuyashesha.Ngaphezu kwalokho, ukuguquguquka kwe-ejenti yokunciphisa amanzi yochungechunge lwe-naphthalene kanye nosimende othile kudinga ukuthuthukiswa.
Izakhiwo:i-ejenti yokunciphisa amanzi esebenza kahle kakhulu inomphumela oqinile wokuhlakazeka kusimende, ingathuthukisa kakhulu ukugeleza kwengxube kasimende nokuwa kokhonkolo, kuyilapho inciphisa kakhulu ukusetshenziswa kwamanzi, ithuthukisa kakhulu ukusebenza kukakhonkolo.Kepha enye i-superplasticizer izosheshisa ukulahleka kokhonkolo, ukuxubana kakhulu kuzopha amanzi.I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ngokuyisisekelo ayishintshi isikhathi sokusetha ukhonkolo, futhi inomphumela wokuvinjelwa kancane lapho umthamo mkhulu (ukufaka umthamo oweqile), kodwa ayilibazisi ukukhula kwamandla okuqala kukakhonkolo oqinile.
Kunganciphisa kakhulu ukusetshenziswa kwamanzi futhi kuthuthukise kakhulu amandla kakhonkolo eminyakeni ehlukene.Uma amandla egcinwa njalo, usimende ungasindiswa ngo-10% noma ngaphezulu.
Okuqukethwe kwe-chloride ion kuncane, akukho mphumela wokugqwala kubha yensimbi.Ingathuthukisa ukungagxili, ukumelana nokuncibilika kweqhwa nokumelana nokugqwala kukakhonkolo, futhi kuthuthukise ukuqina kukakhonkolo.
ISICELO:
1,Ifanele zonke izinhlobo zokwakhiwa kwezimboni kanye nezomphakathi, ukongiwa kwamanzi, ezokuthutha, ichweba, i-precast yobunjiniyela bakamasipala kanye nokhonkolo oqinisiwe ofakwe endaweni.
2,Ifanele amandla aphezulu, amandla aphezulu kanye nokhonkolo wamandla aphakathi nendawo, kanye nezidingo zamandla akuqala, ukumelana nesithwathwa okumaphakathi, ukhonkolo omkhulu we-liquidity.
3, Ifanele amalungu okhonkolo we-precast wenqubo yokwelapha umusi.
4,Ifanele ingxubevange eyahlukene yezingxenye zokuqinisa ezinciphisa amanzi (I-Master Batch).
