Calcium Sulfate Dihydrate

Calcium Sulfate Dihydrate yog ib qho tseem ceeb thiab ntau yam raw khoom hauv kev lag luam. Nws cov yam ntxwv tshwj xeeb muaj xws li: tsis tshua muaj hardness, ua kom yooj yim rau grind rau hauv hmoov; Thaum rhuab mus rau qhov kub thiab txias (kwv yees li 150 degree), nws poob qee qhov ntawm nws cov dej siv lead ua thiab hloov mus rau hemihydrate gypsum (plaster ntawm Paris), cov txheej txheem uas thim rov qab, tso cai rau nws rov ua dej thiab tawv thaum raug dej; nws kuj yog tshuaj ruaj khov, me ntsis soluble hauv dej, thiab cov khoom ntshiab yog dawb thiab tsw. Raws li cov yam ntxwv no, nws cov kev siv tseem ceeb suav nrog: raws li kev ua haujlwm tsis zoo hauv kev lag luam cement los tswj kev teeb tsa lub sijhawm; hauv kev tsim cov khoom siv hauv tsev gypsum (xws li gypsum boards thiab plaster), siv nws lub teeb yuag, hluav taws kub - tiv taus, thiab kub thiab suab rwb thaiv tsev zog tom qab hardening; raws li cov khoom siv pwm thiab kho tus cwj pwm tua hluav taws hauv kev lag luam ceramic; thiab raws li cov av txias hauv kev ua liaj ua teb thiab ua cov coagulant thiab additive hauv kev lag luam zaub mov.

TOPLUS Calcium Sulfate Dihydrate, los ntawm cov txheej txheem purification thiab crystallization siab heev, qhia tau hais tias muaj txiaj ntsig zoo hauv kev lag luam: nws cov khoom muaj purity siab dua thiab zoo ib yam siv lead ua morphology, nrog cov ntsiab lus tsis tshua muaj impurity. Qhov no tso cai rau kom meej meej thiab ruaj khov tswj lub sij hawm thaum siv los ua cement retarder; thiab nyob rau hauv gypsum tsev cov ntaub ntawv ntau lawm, nws enables tsim cov gypsum khoom nrog ib tug ntau yam qauv, siab zog, thiab ntau tswj hardening ceev.
