Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
imikhiqizo yokusheshisa ukhonkolo yiqembu lezixube zamakhemikhali ezengezwe kumxube wekhonkrithi ukusheshisa inqubo ye-hydration nokukhuthaza ukuthuthukiswa kwamandla.. Zibuye zisetshenziselwe ukunciphisa isikhathi sokusetha kanye nokwenza ngcono ukusebenza kokhonkolo, kungakhathaliseki ukwakheka kwengxube.
Ama-Accelerator angenye yezinhlobo ezidume kakhulu zokuxutshwa kwamakhemikhali kokhonkolo, okufana nezinciphisi zamanzi kanye namareta. Lezi zivame ukungezwa kungxube kakhonkolo ngokushesha ngaphambi noma ngesikhathi sokuxutshwa, futhi usebenze ngokukhuphula izinga lokugeleza kwengxube yamanzi usimende.
I-Calcium chloride iwuhlobo oluvame kakhulu lokusheshisa ingxube, kodwa ezinye izinhlobo eziningi ziyatholakala. Lezi zihlanganisa i-sodium thiocyanate, triethanolamine, kanye nezinye izixube ze-nonchloride ezisheshayo.
Ezinye izixube zikakhonkolo zingaba nezinye izakhiwo ezingathinta ukumiswa kanye nokuqina kokhonkolo, njengama-superplasticizers noma izixube zokufaka umoya. Ezinye zalezi zingatholakala kumpushana, i-slurry noma ifomu le-liquid.
Inzuzo ebaluleke kakhulu yokusebenzisa ama-accelerator ukuthi asheshisa isikhathi sokusetha. Lokhu kungonga isikhathi nemali eningi kosonkontileka abafuna ukuqeda umsebenzi ngokushesha.
Bangakwazi ngisho ukusiza abafana bokuhlobisa ehlobo, lapho isimo sezulu sifudumele ngokwanele ukubavumela ukuthi basuse amafomu kusenesikhathi futhi bangene endaweni ekhonkolo ukuze baqedele. Isikhathi sokusetha esisheshisiwe singenza kube lula ukuthola umsebenzi wokulungisa wasendlini wenziwe ngosuku, kusho uGabriel Ojeda, umongameli weFritz-Pak Corp.
Ingxube eyaziwa kakhulu yokusheshisa ukhonkolo i-calcium chloride, kodwa nezinye izinto zingasebenza ngempumelelo. Lezi zihlanganisa ama-chloride ancibilikayo, carbonates, ama-silicates, ama-fluosilicates nezinye izinhlanganisela eziphilayo.
