Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
Inqubo yokukhiqiza ukhonkolo ongasindi wamaselula uhlanganisa ukuhlanganisa izinto zikasimende, iqoqo elimahhadla, i-fiber kanye ne-gas-forming agent ukuze kwakheke udaka oluqinile nolubonakalayo olungakhihliza amagwebu bese lwelapheka endaweni lapho kushiswe khona izinga lokushisa.. Ukukhiqizwa kwalolu hlobo olusha lukakhonkolo kulula kakhulu futhi ukonga okwenza kube enye indlela ethandwayo kunezinhlobo ezivamile zokwakha. Inqubo yokukhipha amagwebu isebenzisa i-Genfil based cellulose organic substance ekhiqiza amabhamuza omoya azinzile anosayizi abahlukahlukene kusukela ku- 0.1 ku 1.5 mm ububanzi. Ingxube ibe isihlanganiswa namanzi bese ithululelwa esikhunjeni ukuze kwakheke okuqinile. Izithako ezihlukahlukene zingengezwa kule ngxube kuhlanganise nomlotha wempukane, i-superplasticizer kanye nama-ejenti okunciphisa ukuncipha.
Izingxube zikakhonkolo zibe sezifakwa esikhunjeni futhi zivunyelwe ukuthi zibekwe ngaphansi kwezimo ezilawulwayo. Ngesikhathi sokuphulukiswa kwe-slurry inyakaziswa njalo ukuze kuqinisekiswe ikhwalithi efanayo kanye nekhwalithi engaguquki. Uma kuthathwa izinyathelo ezifanele zokuvikela udaka ezimeni ezinomoya endaweni yokubeka nokuqinisekisa ukuthi ukhonkolo awuhlukanisiwe ngaphambi kokubeka., imifantu yokuncipha kwepulasitiki ngeke yenzeke.
I-slurry ingathuthukiswa ngokuqhubekayo ngokungezwa kwe-superplasticizer ukuze kwandiswe ukusebenza kwayo emanzini aphansi kanye ne-ejenti efaka umoya ukuze kuthuthukiswe ubukhulu bembobo kakhonkolo nokwandisa amandla ayo.. Lokhu kufezwa ngaphandle kokuthinta isakhiwo seselula sikakhonkolo. Ngaphezu kwalokho, i-ejenti yokunciphisa i-shrinkage yengezwe ukuze kuncishiswe ukuncipha kokumisa nokuqeda ukuqhekeka kokhonkolo. I-ejenti yokunciphisa ukuncipha ikhethwa eqenjini elihlanganisa i-alkyl ether oxyalkylene adducts., i-diethylene glycol, I-dipropylene glycol ne-tripropylene glycol.
