Eminyakeni embalwa edlule, imboni yezokwakha iye yathola ukukhula okuthe xaxa kanye nentuthuko. Lokhu kudingekile ukuthuthukiswa kwama-admixtures anamuhla kanye nezithasiselo. Izengezo kanye nama-admixtures kakhonkolo yizinto zamakhemikhali ezingezwe kukhonkolo ukuze zithuthukise izakhiwo zayo zomzimba nezamakhemikhali. Lezi zingxenye zibonisa imikhiqizo eminingi eneminye yezakhiwo zamakhemikhali ezahlukahlukene.
Umehluko omkhulu phakathi kwama-admixtures nezithasiselo yizigaba lapho izinto zingezwa khona ukhonkolo noma usimende. Izengezo zingezwa kwinqubo yokukhiqiza usimende, ngenkathi ukwengeza ama-admixture kwenziwa lapho kwenziwa ukuxubana kokhonkolo.
Yini izengezo?
Izengezo zengezwa ku-Cument ngesikhathi sokukhiqiza ukuthuthukisa izakhiwo zalo. Imvamisa, izinto ezingavuthiwe ezibandakanyekile ekukhiqizeni usimende zifaka i-alumina, lime, iron oxide, kanye ne-silica. Ngemuva kokuxuba, izinto zokwakha zifudunyezwa cishe ngo-1500 ℃ ukuvumela usimende ukufeza izakhiwo zalo zokugcina zamakhemikhali.
Yini ama-admixtures?
Ama-admixtures kakhonkolo angaba ngezinhlobo ezimbili, ama-organic ne-inorganic. I-Multifunctional Admixtures yilawo aguqula izakhiwo ezingaphezu kweyodwa noma zamakhemikhali zengxube ekhonkolo. Kunezinhlobonhlobo ze-admixtures ezahlukahlukene ezitholakalayo zokushintsha izici ezahlukahlukene zikakhonkolo. Ama-Admixture angahlukaniswa kuwo:
Amanzi anciphisa ama-admixtures
Lezi yizinhlanganisela ezisebenza njengamapulasitiki, ezinciphisa okuqukethwe kwamanzi kokuhlanganiswa ukhonkolo ngangokunokwenzeka ngo-5% ngaphandle kokushintsha ukuvumelana. Ukuncipha kwamanzi okucasulayo kuvame ukuvela okuvela kuma-polycyclic noma ama-phosphates. Uma kungezwa, la ma-admixtures akhulisa amandla acindezelayo we-conkcrete mix ngokwenza kube ngopulasitiki ngokwengeziwe. Lolu hlobo lokuhlanganiswa luvame ukusetshenziswa ngokweqile nangokhonkolo womgwaqo.
Amanani aphezulu aphezulu wamanzi
Lawa ngama-superplastizer, iningi lama-polymer concrete admixtures anciphisa okuqukethwe kwamanzi ngangokunokwenzeka ngama-40%. Ngala ma-admixtures, i-porosion yengxube yehlile, ngakho-ke ithuthukisa amandla nokuqina kwayo. Lezi zinhlamvu zivame ukusetshenziselwa ukuzihlanganisa nokhonkolo ofafazwe.
Ukusheshisa ama-admixtures
Ngokuvamile ukhonkolo kuthatha isikhathi ukuguquka kusuka epulasitiki kuye esimweni esilukhuni. Ama-polyethylene glycols, ama-chlorides, ama-nitrate, nama-fluorides wensimbi ajwayele ukusetshenziselwa ukwenza lezi zinhlobo zama-admixture. Lezi zinto zingangezwa ku-conkcrete mix ukuze zifinyeze isikhathi esithathayo ukuze sihlanganise futhi sibeke.
I-Adming Onchraining Admixtures
Lezi advixtures zisetshenziselwa ukwenza ukuhlanganiswa kokhonkolo ongenela umoya. Banika amandla ukufakwa kwama-bubble zomoya kwingxube ekhonkolo yethu ngakho-ke kuthuthukisa izakhiwo ezinjengokuqina namandla ngokushintsha i-free-thaw yesimende.
Ukubuyisa ama-admixtures
Ngokungafani nokusheshisa ama-admixtures afushaniswa ukuhlanganisa ukuhlanganisa nokusetha, ukubuyisa ama-admixture kukhulisa isikhathi ukhonkolo kudinga ukusetha. Ama-admixturetures anjalo awashintshi isilinganiso samanzi kodwa asebenzise insimbi ye-oxides kanye noshukela wokuvimbela inqubo yokubopha.
I-Concrete AddItives kanye nama-admixtures njengamanje ayisigaba somkhiqizo owenziwa kangcono samakhemikhali wokwakha. EJufu ChemTech, sisebenza nezinkampani zokuhlangana zasendaweni nezenhlalo zokuqinisekisa ukuthi amaklayenti ethu athola imikhiqizo engcono kakhulu yemisebenzi yabo yokwakha. Vakashela iwebsite yethu ukuze ubuke futhi uthenge izengezo zokhokho kakhonkolo ezisebenzayo futhi ezethembekile kanye nokumangaliswa kokhonkolo emhlabeni jikelele. (Https://www.jufumtemtech.com/)
