Nrog rau kev hloov pauv ntawm cov xwm txheej sab nraud, xws li kev hloov pauv ntawm qhov kub thiab txias, siab thiab dej, lub suab pob zeb ua rau lub suab ntawm lub pob zeb semi-hydrous nrog crystallizing dej (CaSO4.1/2H2O) thiab dihydrous gypsum (CaSO4-2H2O) los ntawm hydration tshuaj tiv thaiv. Ntawm qhov tsis sib xws, lub dihydrous gypsum hloov mus rau hauv ib nrab-hydrous gypsum los ntawm cov tshuaj tiv thaiv lub cev qhuav dej, thiab lub cev qhuav dej tau hloov mus rau hauv cov dej tsis muaj gypsum.
(CaSO4). Nyob ntawm cov xwm txheej ntawm cov dej thiab lub cev qhuav dej, xws li qhov kub thiab txias, qhov siab, qhov feem ntawm cov dej, thiab cov impurities qhia, gypsum tuaj yeem tsim ntau yam sib txawv. Cov variants no muaj cov ntsiab lus sib txawv ntawm cov dej crystalline thiab crystal theem xeev. Cov kev sim tau pom tias cov txheej txheem ntawm lub cev qhuav dej thiab dej yog qhov nyuaj thiab ntau qhov kev tshwm sim tshwm sim nyob rau tib lub sijhawm, yog li ob qho tib si ntuj gypsum thiab cov khoom ua tiav gypsum yog cov sib xyaw ntawm ntau qhov kev hloov pauv ntawm gypsum. Nws feem ntau lees txais tias gypsum muaj 5 theem xeev thiab 7 qhov sib txawv: dihydrous gypsum (D) -CaSO42H2O; (H) CaSO4.2H2O( faib ua hom thiab hom; Hom II anhydrous gypsum AII) -- CaSO4a hom; Hom II anhydrous gypsum; Hom I anhydrous plaster (AI). Raws li cov yam ntxwv ntawm ntau yam kev hloov pauv, cov tuam txhab gypsum tau tsim ntau yam khoom siv gypsum nrog cov txiaj ntsig zoo, tsim kev lag luam loj.
Kev siv fluoride gypsum: Nyob rau hauv lub ntsej muag ntawm lub roob ntawm phosphogypsum (phosphate fertilizer cog), desulfurized gypsum (thermal fais fab nroj tsuag), fluoride gypsum (fluoride ntsev cog) thiab lwm yam kev lag luam pov tseg, yuav ua li cas nrog tau ua mob taub hau rau tsoom fwv thiab cov tuam txhab muaj feem cuam tshuam, pov tseg, stacking tsis tuaj yeem daws qhov teeb meem, thiab ua rau muaj kuab paug thib ob ntawm ib puag ncig. Cov khoom siv kho mob hauv tsev uas twb muaj lawm muaj qhov tsis xws luag xws li kev nqis peev loj, kev tsim kho lub sijhawm ntev thiab tsis paub tab, yog li Guiyi Building Materials Technology Co., LTD. Tsim lub zog siab dej resistant gypsum ecological cib thev naus laus zis thiab cov cuab yeej tshwj xeeb ntau lawm ua tiav cov teeb meem saum toj no. Nws tseem yog thawj lub lag luam hauv Suav teb los tsim gypsum ecological cib tshuab thiab cov khoom siv tshwj xeeb uas siv cov khoom pov tseg xws li desulfurized gypsum, phosphogypsum thiab fluoropgypsum. Kwei Machinery Factory tshwj xeeb hauv kev tsim thiab tsim cov fluoropgypsum pelleting, fluoropgypsum pelleting tshuab, fluoropgypsum pelleting tshuab, fluoropgypsum pelleting tshuab thiab desulfurized gypsum pelleting tshuab, thiab tsim ntau yam metallurgical hmoov txias pressing pellets. Txhua yam khoom siv hmoov, yuav tsum tau nias lub pob kom ua tiav lub tshuab pob, xws li: hmoov coke, coke hmoov txhua yam uas tsis yog-ferrous hlau hmoov, oxide hlau thiab plua plav, sludge, resistant cov ntaub ntawv, thiab lwm yam. Fluorine gypsum pob pressing tshuab series yog cov khoom siv raw tom qab sib tsoo ncaj qha rau ntawm lub tshuab ntau lawm, tsis tas yuav tsum tau ntxiv dej, lub hom phiaj yog txo cov plua plav, tswj lub peev xwm, rov qab siv dua, txhim kho cov yam ntxwv ntawm kev thauj mus los thiab lwm yam tsim muaj peev xwm yog siv rau cov hmoov qhuav qhuav rau hauv cov pelleted. magnesium txheej txheem noob. Cov koob ntawm desulfurized gypsum pob nias tshuab tuaj yeem hloov kho los ntawm hydraulic siab los txhim kho lub zog siab.
