Isifinyezo
I-OBC-LES ibizwa nangokuthi i-Silica fume noma i-Condensed Silica fume.Ikhiqizwa lapho i-ferroalloy isetshenziselwa ukuncibilikisa i-ferrosilicon kanye ne-silicon yezimboni (i-silicon yensimbi), inani elikhulu le-SiO2 eguquguqukayo kakhulu kanye ne-Si gas ikhiqizwa ngaphakathi kwesithando somlilo esincibilikisa i-ore, futhi igesi ikhishwa nge-oxid ngokushesha, ifinyele futhi igcwale umoya ngemva kokuphuma.Kuwumkhiqizo ophumayo wokuncibilikisa izimboni ezinkulu, futhi ukususwa kothuli kanye nemishini yokuvikela imvelo kuyadingeka ukuze kugaywe kabusha phakathi nayo yonke inqubo.Ngenxa yesisindo sayo esilula, imishini yokubethela nayo iyadingeka.
Ebunjiniyela be-cementing, i-OBC-LES isetshenziselwa ukulungisa udaka lukasimende futhi inomsebenzi wokuvimbela umzila wegesi kanye nomzila wamanzi, ukunciphisa ngokuphumelelayo isikhathi soguquko lokuthuthukiswa kwejeli le-siment slurry static, ukuthuthukisa ukuzinza kwe-slurry kasimende namandla okusetha usimende. .
