1, gypsum self-leveling batch stability tsis zoo (kev txav tsis tau raws li tus qauv, los ntshav)
Kev txhais lus: Qhov sib txawv ntawm qhov chaw ntawm lub tsev gypsum muaj qhov sib txawv ntawm qhov kev thov ntawm cov dej txo tus neeg sawv cev. Thaum qhov tshwj xeeb ntawm thaj chaw yog tsawg dua 8130cm2 / g, qhov kev sib raug zoo ntawm lub peev xwm adsorption thiab dispersion ntawm cov dej txo tus neeg sawv cev yog pom tseeb dua. Vim qhov sib txawv fineness, lub peev xwm adsorption ntawm cov dej reducer cuam tshuam ntau dua, thiab cov dej txo tus nqi sib txawv heev.
2, lub teeb plaster plaster smeared ntawm phab ntsa tsw loj
Txhais: Cov ntxhiab tsw ntawm desulfurized gypsum kho nrog ammonia cuam tshuam rau kev xa khoom, uas tuaj yeem daws tau los ntawm kev ntxiv qee feem ntawm cov txiv qaub ceev.
3, nrog desulfurized gypsum ntau lawm nto txheej plaster gypsum paj, thiab nyias txheej ntawm cov hmoov hauv zos, tuab txheej ntawm lub zos xim sib sib zog nqus zog yuav ua tau.
Kev txhais lus: Cov hmoov calcium hnyav ntxiv ntau dhau vim nws qhov inertia thiab xim sib txawv
4, raws li cov cement dawb hauv qab no 80, hnyav calcium 900, BP24 2, U40,000 3.2 starch ether 0.5, bentonite 20 scrape rau phosphite plaster plaster nto tawm ntawm daim tawv nqaij
Kev txhais lus: Phosphogypsum shrinkage yog loj heev, yog tias koj xav tau los npog qhov kev tsim kho yuav tsum nyob rau hauv lub sij hawm pib, overdue nyuaj rau kev koom tes, putty yog ib qho yooj yim mus rub.
5, huab cua thaiv txheej txheej hnyav xim gypsum, kev tsim kho ntawm 2-3cm, dai net thib ob tsim ntawm 2-3mm, depowder nto.
1) Cov txheej txheej nyias yuav tsum muaj cov calcium uas hnyav dua, 1t tsis tshaj 100kg, txwv tsis pub lub zog saum npoo yog tsawg dhau, qhov sib npaug ntawm cov cellulose yuav tsum muaj ntau dua; 2) Ningxia ntuj gypsum mine vim tsis muaj dej dawb hauv cov ore, dej tsis txaus, ntxuav kev kho ua ntej calcination, cov dej dawb ntawm cov hmoov mine tsawg kawg yog 5% rau calcination, Ningxia lub ntuj siv lead ua tsis tiav, ua rau tawg ntawm siv lead ua nto. Nws raug nquahu kom ntxiv qee qhov desulfurized gypsum.
6, gypsum tuaj yeem ntxiv cov hmoov roj hmab los txhim kho kev ua haujlwm?
Cov yeeb yaj kiab tsim cov hmoov roj hmab cuam tshuam rau cov evaporation ntawm dej, thiab nws lub zog muaj kev cuam tshuam zoo heev.
7, vim li cas gypsum zoo dhau lawm, thaj chaw tshwj xeeb yog loj dhau, tab sis lub zog raug txo?
Yog hais tias tus nqi dissolution qeeb los yog tus nqi ntawm dissolution ntau dhau lawm, nws yuav ua rau supersaturation mus ntev dhau lawm, tsim muaj ntau crystalline nuclei, thiab tsim zoo crystals, uas yog khi ua kom ntau crystallization kev nyuaj siab, rhuav tshem cov tsim crystalline qauv. , thiab thaum kawg txo lub zog.
8, cov neeg siv khoom pleev xim gypsum tsis zoo siv "nqus", lub zog tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Ntxiv calcium formate zoo tsim, zog.
9. Teeb meem kev laus
Kev laus tsim nyog yog tsis yooj yim sua nyob rau hauv loj-scale ntau lawm, tej yam ntuj tso aging rau tsawg kawg yog ib nrab ib hlis, ntau tshaj 100 tons ib hnub twg nyob rau hauv lub Hoobkas, ua rau cov khoom muag teeb meem, nyob rau tib lub sij hawm, yog hais tias lub gypsum yog underburned, lub zog ntau dua. phem dua.
10. Rau plaster plaster, me me tawg tshwm tom qab cua tshuab
Nws raug suav hais tias yog kev ua haujlwm tawg, gypsum tsis ruaj khov, thiab qhov no tau ua dhau los, thiab calcium tsis hnyav dua thaum ntxov. Cov khoom siv nquag yuav tsum tau nce cov calcium hmoov kom txo tau nws cov haujlwm, thiab cov hmoov calcium hnyav tsis koom nrog cov tshuaj tiv thaiv, thiab qhov kev tawg no yog tshuaj lom neeg tawg. Cua tawg, thiab tus nqi ntawm retarder ntxiv kuj muaj feem xyuam, ntxiv ntau tshaj li ib nrab hnub tsis ua.
