Umgangatho ophezulu wokunciphisa amanzi kunye ne-arhente yokunciphisa amanzi eSiqhelo

Umhla wokuPoswa:7,JAN,2022

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. isitishi ukumisela, ukufezekisa ukubakho kolwakhiwo.Ukwenzela ukwenza ulwakhiwo olunokwenzeka, ngokuqhelekileyo songeza ezinye ii-retarders, ii-arhente zokungenisa umoya, ii-arhente zokukhupha ugwebu, izigcina-zigcina, ii-agent ezityebisayo, ebusika. ixesha 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.Ziyi-admixtures eziyimfuneko kubunjineli bokwakha.Nangona kunjalo, ngophuhliso lobugcisa, isiphumo se-arhente yokunciphisa amanzi siya sisiba ngakumbi. kwaye kucace ngakumbi, phakathi kwayo i-arhente yokunciphisa amanzi esebenzayo ibonakala ngakumbi ekunciphiseni kwamanzi 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 zokunciphisa amanzi aphezulu kwikhonkrithi ehambayo; Izinga lokunciphisa amanzi kwi-arhente yokunciphisa amanzi eqhelekileyo iphantsi kakhulu isetyenziselwa ukulungiswa komgangatho wamandla. ayikho phezulu, iimfuneko zokunciphisa amanzi aphantsi kwikhonkrithi.
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 kakuhle kakhulu kune-arhente yokunciphisa amanzi eqhelekileyo inokunciphisa amanzi angcono, ukusasazwa, kunye nesiphumo esiphuculweyo, kunye nomsebenzi wokunciphisa amanzi kunye nezinye izinto ezininzi ezisebenza ngokufanelekileyo zokunciphisa amanzi, njengamandla angaphambili amandla aphezulu okunciphisa amanzi, i-ejenti yokunciphisa amanzi ephelelwe ngamandla, i-air-entraining esebenzayo i-jianshuiji i-geometric constituent ye-synthetic ephezulu yokunciphisa amanzi ineenzuzo ezininzi, ingaba ngcono. ukuhlangabezana nekhonkrithi entsha kunye nokusebenza kwekhonkrithi eqinileyo yeemfuno ezahlukeneyo.
