Qee Cov Lus Nug txog Hydrophobic Silica
Q: Dab tsi yog hydrophobic silica?
A: Hydrophobic silicon dioxide feem ntau yog cov khoom lag luam tom qab kev kho mob. Cov khoom cuam tshuam nrog qhov tsim nyog sib txuas los ntawm cov pab pawg silane; cov khoom yog hydrophobic vim muaj qhov ua haujlwm sib txawv ntawm cov pawg methyl uas tsis muaj hydrolyzed.
Tsis zoo li cov tshuaj hydrophilic silica, tsis tuaj yeem ntub dej los ntawm dej. Txawm hais tias hydrophobic silica muaj denser dua dej, nws tuaj yeem ntab saum nplaim dej. Tom qab hloov ua hydrophobicization, qhov dej nqus yuav txo ntau heev piv nrog cov thawj hydrophilic vapor theem silicon carbide.
Los ntawm kev kho saum npoo ntawm silica, nws cov khoom muaj peev xwm ua tau zoo hauv qee qhov kev thov tshwj xeeb, uas tuaj yeem txhim kho rheological cov khoom ntawm cov kua polymer ua ntau, tshwj xeeb tshaj yog nyob rau hauv epoxy resin tshuab.
2.Q: Dab tsi yog qhov ntau lawm ntawm hydrophobic ppt silica?
A: Cov npliag dej ua kua silica yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov kua dej kua iav thiab muaj cov tshuaj sulfuric acid, uas lim los ntawm lub thav duab thiab lim rau cov tshuaj tsis haum hauv qab 1%. Tom qab lim, lub ncuav mog qab zib yog do rau hauv slurry, thiab cov slurry tau puv nrog cov kev hloov kho. Lub pas dej hydrophobic carbon dub masterbatch tau los ntawm kev siv tshuaj tsuag kom qhuav, thiab tom qab ntawd cov khoom kawg tau npaj los ntawm kev txua cov cua.
3.Q: Thiab yuav ua li cas los tswj kev tswj hwm qhov zoo ntawm koj cov khoom lag luam loj?
A: DCS tswj yog saws hauv cov txheej txheem ntau lawm, thiab cov khoom zoo kuj ruaj khov. Muaj kev tswj hwm nruab nrab thiab ex-Hoobkas kev tswj hwm rau cov loj ntau lawm ntawm cov khoom tiav, thiab ex-Hoobkas zoo ntawm cov khoom tiav yog nruj me ntsis tswj.
