Izicelo zaManzi aphezulu okuNciphisa ixabiso lePCE Superplasticizers

Kutheni Usebenzisa iPCE Superplasticizers?

Polycarboxylate ether (PCE) superplasticizers zibonelela ngexabiso eliphezulu lokunciphisa amanzi. Oku kubonisa ukuba bakuvumela ukuba usebenzise amanzi amancinci kwikhonkrithi ngelixa ugcina kulula ukusebenza. Amanzi amancinci kakhulu abangela ukomelela, ikhonkrithi eyomeleleyo ngakumbi. Abakhi kunye nabayili bakhetha ii-PCE superplasticizers kwisakhiwo sanamhlanje apho ukusebenza kakuhle kubalulekile.

Usetyenziso oluPhambili kwiZakhiwo kunye noKwakha

Ikhonkrithi ephezulu yamandla: I-PCE superplasticizers inceda ukwenza ikhonkrithi ene-compressive staminas ngaphezulu 60 MPa. Bagcina i-mix fluid nangona umxholo wewebhu wamanzi aphantsi. Oku kuyimfuneko kwizakhiwo eziphakamileyo, iibhulorho, kunye nezakhiwo zomthwalo onzima.

I-self-compacting concrete (SCC): I-SCC iqukuqela ngqo kwiindawo ezixineneyo ngaphandle kokungcangcazela. I-PCE superplasticizers ibonelela nge-SCC ulungelelwaniso olufanelekileyo lokujikeleza kunye nokuzinza. Iikontraka zisebenzisa lo mxube kwiintlobo ezintsonkothileyo okanye iindawo ezine-rebar eshinyeneyo.

I-precast kunye ne-prestressed components: Iifektri ezenza amacandelo e-precast zifuna ukusekwa ngokukhawuleza kunye nokuzuza amandla kwangoko. Izongezo ze-PCE zigcina ukubunjwa ngokukhawuleza kunye nomgangatho ophezulu rhoqo. Ukongeza, bathoba iziphene kwindawo efana nencindi yobusi.

Ulwakhiwo oluhlala luhleli: Ngokunciphisa ukusetyenziswa kwamanzi, Ii-superplasticizers ze-PCE zenza kube lula ukutshintshwa kwekhonkrithi ngothuthu lwempukane okanye i-slag. Oku kunciphisa i-carbon footprint yekhonkrithi ngaphandle kokulimaza ukusebenza.

5 Ii-FAQ zoMgangatho wokuNcitshiswa kwaManzi aphezulu ePCE iiSuperplasticizers zeConcrete Polycarboxylate Ether Based Superplasticizer

Imibuzo Ebuzwa Rhoqo malunga nokuNcitshiswa kwaManzi aphezulu PCE Superplasticizers

Yintoni i-PCE superplasticizer?

I-PCE superplasticizer sisongezo sekhemikhali esenziwe ngepolycarboxylate ether. Ixutywe kwikhonkrithi ukunciphisa umthamo wamanzi afunekayo. Oku kunceda ukwenza ikhonkrithi yomelele kwaye kube lula ukuyibeka ngaphandle kokuphulukana nokusebenza.

Kutheni inikezela ngokunciphisa amanzi aphezulu?

Iimolekyuli ze-PCE zinesakhiwo esikhethekileyo esisasaza amaqhekeza e-samente ngokulinganayo kumxube. Oku kuthintela amasuntswana ekubeni adibane. Nje ngeziphumo, amanzi amancinci afunekayo ukugcina ulwelo lwekhonkrithi. Ukunciphisa amanzi kunokufikelela 30% okanye ngaphezulu, kuxhomekeke kuyilo lomxube.

Ichaphazela njani amandla ekhonkrithi?

Ngokunciphisa umxholo wamanzi ngelixa ugcina ukusebenza, umlinganiselo wesamente wamanzi uyehla. Umlinganiselo osezantsi uthetha ikhonkrithi exineneyo. Ikhonkrithi exineneyo ikhokelela kuxinzelelo oluphezulu kunye namandla aguquguqukayo ngokuhamba kwexesha.

Ngaba iyahambelana neminye imixube?

Uninzi lwee-superplasticizers ze-PCE zisebenza kakuhle kunye ne-admixtures eqhelekileyo njenge-air-entrainers okanye i-retarders.. Kodwa hlala uvavanya umxube opheleleyo ngaphambi kokusetyenziswa okukhulu. Ezinye iindibaniselwano zinokubangela amaxesha okumisela angalindelekanga okanye ilahleko yokuwa.

Ziziphi iingcebiso zokugcina kunye nokuphatha?

Gcina i-PCE superplasticizer kwindawo epholileyo, indawo eyomileyo kude nelanga elithe ngqo. Gcina izikhongozeli zivaliwe xa zingasetyenziswa. Kuphephe ukukhenkceza. Vuthulula okanye uvuthulule imveliso phambi kokusetyenziswa ukuba ukwahlukana kwenzeka. Landela imiyalelo yokhuseleko kwileyibhile kwaye unxibe izixhobo ezifanelekileyo zokukhusela ngexesha lokuphatha.
