Kev tsim cov khoom muaj zog gypsum hmoov

           Qhov thib ob Zhangbei Chemical Factory tau ua tiav cov txheej txheem ntawm cov khoom siv tshuaj ntxiv, thiab ua rau nws faib nrog fluoropgypsum. Tom qab ci thiab pob milling, lub zog siab gypsum hmoov tau npaj, uas yog lub npe hu ua FS-A hom sab hauv phab ntsa kho kom zoo nkauj hmoov. Cov khoom yog tsuas yog siv nyob rau hauv lub tsev sab hauv phab ntsa, qab nthab hauv qab thiab nto txheej plastering, tsis muaj fiber ntau mixing, yooj yim siv; Muaj zog adhesion, tsis txhob poob tshauv: nto txheej nyuaj ci; Tsis tawg, nruas, shedding phenomenon. Tom qab ntau tshaj li ob xyoos ntawm kev sim, cov neeg siv cov lus teb tau zoo. Qhov nruab nrab ntsuas flexural thiab compressive zog ntawm tus qauv ntsuas ntsuas ntawm cov khoom no yog 3.0MPa thiab 12.6MPa, thiab tuaj yeem ncav cuag 3.8MPa thiab 17.0MPa ntawm qhov kub thiab txias. Lub zog txuas ntxiv mus ntxiv rau lub sijhawm tom qab, thiab lub zog flexural thiab compressive mus txog 5.3MPa thiab 26.0MPa tom qab ib hlis.Nws yog ntau dua li cov ntaub ntawv teev tseg ntawm flexural thiab compressive zog ntawm 3.0MPa thiab 5.0MPa rau cov khoom lag luam zoo tshaj.Li Zhengrong et al. tsim ib tug zoo tagnrho additive formula, thiab ua nws proportionally tov nrog fluoropgypsum. Tom qab ziab thiab pob milling, siab zog gypsum hmoov tau npaj. Table 1-6 teev cov specifications ntawm cov khoom.
