Isikhala Esimelana Nokushisa Okuphezulu se-FC-S60S
Isithasiselo se-spacer, esingasusa uketshezi lokubhoboza ngempumelelo, siyakwazi ukuvimbela ukuminyana kwesimende ekuhlanganeni nalo. Sinomphumela wokujiya ku-slurry yesimende ngaphansi kwezimo ezithile, ngakho-ke, inani elifanele lama-chemical inert space agents kufanele lisetshenziswe ukuze kuhlukaniswe ne-slurry yesimende. Amanzi amasha noma amanzi axubayo angasetshenziswa njenge-chemical inert space agent.
• I-FC-S60S iyi-spacer engamelani nokushisa okuphezulu, ehlanganiswa yizinhlobo ezahlukene zama-polymer angamelani nokushisa.
• I-FC-S60S inokumiswa okuqinile futhi ihambisana kahle. Ingahlukanisa ngempumelelo uketshezi lokubhoboza kanye ne-simende lapho ishintsha uketshezi lokubhoboza, futhi ivimbele ukukhiqizwa kwe-slurry exubile phakathi koketshezi lokubhoboza kanye ne-simende.
• I-FC-S60S inobubanzi obukhulu bokulinganisa isisindo (kusukela ku-1.0g/cm3kuya ku-2.2g/cm3Umehluko wobuningi obuphezulu nobuphansi ungo-lees kuno-0.10g/cm23ngemva kokuba i-spacer ihlale amahora angama-24.
I-spacer ilungiswa ngezici ezithile zoketshezi, njengokuthamba kanye nobuningi, ezenzelwe ukususa uketshezi lokubhoboza ngenkathi kuvumela ukufakwa kwesigxobo esiphelele sikasimende. I-FC-S60S iyinto engeziwe enenani egxile kumakhasimende futhi eqhutshwa yizixazululo, ihlonipha yonke imininingwane, imithethonqubo yezemvelo kanye nezinqubo zokuqinisekisa ikhwalithi eziqinile.

I-spacer iwuketshezi olusetshenziselwa ukuhlukanisa uketshezi lokubhoboza kanye nama-slurry okuqinisa ukhonkolo. I-spacer ingaklanywa ukuthi isetshenziswe noketshezi lokubhoboza olusekelwe emanzini noma olusekelwe ku-oyili, futhi ilungiselela kokubili ipayipi kanye nokwakheka kokusebenza kokuqinisa ukhonkolo. Ama-spacer ngokuvamile aqiniswa ngama-ejenti okulinganisa anganyibiliki. Anethonya lokujiya kuma-slurry esimende ngaphansi kwezimo ezithile, ngakho-ke, inani elifanele lama-ejenti okuhlukanisa amakhemikhali angangeni kufanele lisetshenziswe ukuze lihlukaniswe ne-slurry yesimende.
