Kev siv cov khoom lag luam los ntawm gypsum txuas ntxiv nthuav dav

Gypsum yog ib yam khoom uas tsis tshua muaj carbon, ntsuab thiab recyclable. Nrog kev txo qis ntawm ntuj gypsum, kev lag luam los ntawm cov khoom gypsum yog dav siv hauv engineering. Tsis ntev los no muaj nyob rau hauv Guilin, Guangxi xeev, Marine cov ntaub ntawv innovation thiab industrial by-product gypsum siv seminar, ib tug xov tooj ntawm kev lag luam kws txawj taw tes hais tias nyob rau hauv lub keeb kwm yav dhau ntawm "ob chav carbon", industrial by-product gypsum khoom yog tsawg-carbon khoom, nws daim ntawv thov dav yuav ua rau cov pa roj carbon emission txo ntawm cov khoom siv hauv tsev. Nyob rau hauv kev pom ntawm tus nqi siab siv cov khoom lag luam los ntawm cov khoom gypsum, xibfwb Duan Pengxuan ntawm Guilin University of Technology tau hais tias kev lag luam los ntawm cov khoom gypsum yog cov khoom siv zoo gypsum, thiab cov khoom lag luam los ntawm gypsum uas ua tau raws li qhov yuav tsum tau ua. tsim cov khoom zoo gypsum. Nrog rau kev tsim nyog gypsum citrate, phosphogypsum thiab desulphurized gypsum raws li cov ntaub ntawv raw, cov txheej txheem autoclaved microcrystalline tuaj yeem siv los tsim cov khoom lag luam zoo -hemihydrate gypsum nrog cov khoom siv siab tshaj 40. Txoj kev loj hlob ntawm -gypsum yog tib txoj hauv kev rau kev txhim kho kev lag luam gypsum. . Duan Pengxuan tau taw qhia tias tam sim no, gypsum cov khoom lag luam nrog cov khoom lag luam los ntawm gypsum raws li cov ntaub ntawv raw tau siv dav hauv kev kho vaj tsev sab hauv, uas muaj cov txiaj ntsig tseem ceeb hauv kev sib raug zoo, ib puag ncig thiab kev lag luam, thiab tuaj yeem ua rau muaj txiaj ntsig rau cov pa roj carbon emission txo. Raws li qhov teeb meem ntawm kev siv phosphogypsum tam sim no nyuaj, tus xibfwb Liu Gang ntawm Wuhan University of Technology tau taw qhia tias kev sib tsoo sov ntawm phosphogypsum tuaj yeem txhim kho lub zog thiab ntim ruaj khov ntawm phosphogypsum cement, kev nthuav dav ntawm perphosphogypsum MAAs tuaj yeem txo qis qis. Kev tawg ntawm txoj kev dej ruaj khov, piv nrog Portland cement zoo tib yam, Cov khoom sib xyaw ua ke raws li perthiophosphosum thiab phosphogypsum muaj cov khoom zoo dua gelling. "Nyob rau hauv xyoo tas los no, kev siv cov khoom lag luam suav nrog cov khoom lag luam gypsum tau nthuav dav, nthuav dav hauv cov nplai thiab txhim kho hauv qib kev ua haujlwm." Yuan Hongwen, tus thawj coj ntawm Zhongshan Jiake Environmental Protection Technology Co., LTD., ntseeg hais tias tseem muaj ntau yam teeb meem uas yuav tsum tau daws nyob rau hauv txoj kev loj hlob tam sim no ntawm kev lag luam, uas yuav tsum tau muaj kev siv zog tas li ntawm kev lag luam. Raws li ib qho kev lag luam ntawm phosphogypsum daim ntawv thov, Yang Bulei, tus thawj coj ntawm Green Environmental Protection Industry Company ntawm Guizhou Phosphogypsum Group, tau tham txog kev tsim kho kev lag luam ntawm phosphogypsum kev siv dav dav raws li lub tuam txhab kev coj ua. Sun Zhenping, tus xibfwb ntawm Tongji University, tau tshuaj xyuas qhov muaj pes tsawg leeg ntawm phosphogypsum tau los ntawm cov qauv coj hauv Guizhou, Sichuan thiab Hubei, thiab tsim cov phosphogypsum composite cementing khoom raws li cov tshuaj tiv thaiv kinetics ntawm hydraulic composite cementing khoom thiab kev cia siab ntawm lub hom phiaj hydration. cov khoom. Nws tuaj yeem hais tias nrog kev txhim kho ntawm kev lag luam thiab kev nce qib ntawm cov thev naus laus zis, kev siv dav dav ntawm kev lag luam los ntawm cov khoom gypsum yuav ua rau muaj kev txhim kho ntau dua.
