Polycarboxylic acidUtywala lukamama lwenziwe ngokuthe ngqo okanye uxinaniso luphezulu kakhulu, ulwelo lukamama lube kugxininiso oluqhelekileyo lwesinciphisi samanzi alukho ulwelo olulula, kulwelo lukamama lube sisinciphisi samanzi esiqhelekileyo ngokwezinto zesanti ozisebenzisayo kunye neemeko zemozulu zalapha ekhaya okanye iimfuno zomxube wekhonkrithi. kwisikhululo ukugqiba, ukuphumeza ukuba kunokwenzeka ukwakhiwa. Ukuze wenze ulwakhiwo lwekhonkrithi lunokwenzeka, ngokubanzi songeza ezinye ii-retarders, ii-agent zokungenisa umoya, ii-arhente zokukhupha ugwebu, izigcina-mpahla, ii-agent ezityebisayo, ngexesha lasebusika liyakongeza i-antifreeze.
I-arhente yokunciphisa amanzi ngumxube oqhelekileyo wekhonkrithi, ayichaphazeli ukwakhiwa kwekhonkrithi kunye neemeko ezilula, inesiphumo sokunciphisa amanzi kunye nokuphucula ikhonkrithi, i-arhente yokunciphisa amanzi asebenzayo kunye ne-arhente yokunciphisa amanzi eqhelekileyo bayakwazi ukuphucula ngokufanelekileyo ukudibanisa izinto eziphathekayo. Ukusebenza okuguquguqukayo kwe-concrete admixture.Ziyimixube eyimfuneko kubunjineli bokwakha.Noko ke, ngophuhliso lwetekhnoloji, isiphumo searhente yokunciphisa amanzi siya sicaca ngakumbi nangakumbi, phakathi apho iarhente yokunciphisa amanzi esebenzayo ibonakala ngakumbi ekucutheni amanzi kunye nezinye. iziphumo.Ngoko kwi-arhente yokunciphisa amanzi esebenzayo ekugqibeleni yintoni ehamba phambili?Masifunde ngakumbi.
I-arhente yokunciphisa amanzi esebenza kakuhle kakhulu ibhekiselele kuyopolycarboxylatesiplasticizerarhente yokunciphisa amanzi, kunyepolycarboxylic acidarhente yokunciphisa amanzi yahlulwe kwi-polycarboxylic acid eqhelekileyo arhente yokunciphisa amanzi ngepolycarboxylatesiplasticizeri-arhente yokunciphisa amanzi esebenza kakhulu;
1.I-arhente yokunciphisa amanzi eqhelekileyo izinga lokunciphisa amanzi lidla ngokuba yi-5% ~ 10%;Ukusebenza kwe-arhente yokunciphisa amanzi kunokufikelela kwi-12% ~ 25% okanye nangaphezulu.
I-2.I-arhente yokunciphisa amanzi esebenza kakuhle inokuba kumlinganiselo wesamente yamanzi phantsi kwemeko efanayo, iphucula kakhulu umsebenzi wekhonkrithi njengokuxuba i-arhente yokunciphisa amanzi esebenza kakuhle inokulungela ukudilika i-25cm yekhonkrithi enkulu yamanzi, ngaxeshanye. Awuyi kungenisa umoya ogqithisileyo, awusayi kukhokelela kwisetingi ecothayo kakhulu; Phantsi kwemeko yedosi yesamente engaguqukiyo, ukudilika kwekhonkrithi exutywe nearhente yokunciphisa amanzi kuqhelekile malunga ne-10cm.
3.Ekuwohlokeni kweemeko ezifanayo ezisisiseko, ukusebenza okuphezulu kokunciphisa amanzi kunokunciphisa kakhulu ukusetyenziswa kwamanzi komxube wekhonkrithi, ukunciphisa kakhulu umlinganiselo wesamente yamanzi, ukuze kuphuculwe kakhulu amandla ekhonkrithi, ngoko ke amandla aphezulu okunciphisa amanzi. isetyenziselwa ikakhulu ukumiswa komgangatho wamandla aphezulu, iimfuno zokucuthwa kwamanzi aphezulu kwikhonkrithi ehambayo; Izinga lokunciphisa amanzi kwi-arhente yokunciphisa amanzi eqhelekileyo iphantsi kakhulu isetyenziselwa ukulungiswa komgangatho wamandla ayikho phezulu, iimfuno zokunciphisa amanzi aphantsi kwekhonkrithi.
4.Ngokweendleko zokulungiselela, i-polycarboxylic acid esebenzayo yokunciphisa amanzi inomxholo ophezulu oqinileyo, ngoko ke ixabiso layo liphezulu kakhulu;Kwaye umxholo oqinileyo wokunciphisa amanzi oqhelekileyo uphantsi, ixabiso nalo linokuba ngaphantsi.
I-arhente yokunciphisa amanzi esebenza ngokufanelekileyo kune-arhente yokunciphisa amanzi eqhelekileyo inokunciphisa amanzi angcono, ukusasazwa, kunye nesiphumo esiphuculweyo, kunye nomsebenzi wokunciphisa amanzi kunye nezinye izinto ezidibeneyo ezisebenza ngokufanelekileyo zokunciphisa amanzi, njengamandla angaphambili amandla aphezulu okunciphisa amanzi, i-arhente yokunciphisa amanzi ecuthekileyo, i-air-entraining esebenzayo i-jianshuiji geometric constituent of synthetic high-high performance yokunciphisa i-ejenti ineenzuzo ezingaphezulu, inokuhlangabezana ngcono nekhonkrithi entsha kunye nokusebenza kwekhonkrithi eqinileyo yeemfuno ezahlukeneyo.
