Calcium sulfate tseem hu ua gypsum nyoos, gypsum nyoos tawv, Muriacite, anhydrous gypsum. Cov siv lead ua orthorhombic tsis muaj xim (β hom) lossis monoclinic siv lead ua (α hom). Qhov hnyav molecular piv txwv 136.14. Qhov ceev sib piv 2.960. Melting point 1193 ℃ (hloov pauv los ntawm β hom mus rau α hom), 1450 ℃ (α hom, thiab decomposed). Me ntsis soluble hauv dej (0.209 ntawm 20 ℃), soluble hauv acid, ntsev ammonium, sodium thiosulfate, sodium chloride kua thiab glycerol. Txawm tias ntxiv dej, nws tsis tuaj yeem ua calcium sulfate dihydrate. Yog tias cov gypsum ntuj raug qhuav tag hauv qab 300 ℃, soluble anhydrous gypsum soluble hauv dej tuaj yeem tsim tau; yog tias cov gypsum ntuj raug cua sov rau saum 600 ℃, insoluble anhydrous gypsum tsim tau. Thaum anhydrous calcium sulfate lossis plaster ntawm Paris raug sib xyaw nrog cov dej kom raug, nws maj mam khov. Nws yog siv los ua cov tshuaj tiv thaiv, cov nplaum, cov dej noo, cov hmoov txhuam, cov ntawv sau, cov roj desiccant, cov ntaub qhwv plaster, thiab cov khoom siv tes ua. Gypsum yog siv los ua cov khoom siv raw rau kev ua cement, thiab nws tuaj yeem kho lub sijhawm teeb tsa ntawm cement. Nws yog siv los ua cov coagulant hauv kev ua tofu, pub poov xab, cov khoom tswj khob noom cookie, thiab cov neeg sawv cev chelating. Muaj cov chaw tsim gypsum ntuj, thiab cov khoom seem ntawm kev lag luam phosphate muaj calcium sulfate. Cov kua ammonium sulfate cuam tshuam nrog cov kua calcium chloride, thiab kev lim, ntxuav thiab nag tuaj yeem tsim cov khoom ntshiab.

Kev ua zaub mov:
Calcium sulfate siv tau ua ib yam khoom siv kho hmoov nplej (ua ib yam tshuaj rau benzoyl peroxide), siv tau ntau tshaj 1.5 grams ib kilogram; siv ua ib yam khoom siv coagulant hauv kev ua zaub mov. Siv ua tofu, thiab ntxiv li 14-20 grams ib liter ntawm taum pauv rau hauv mis taum pauv (yog ntau dhau yuav ua rau iab). Ntxiv rau hmoov nplej ntawm 0.15% thiab siv ua khoom noj poov xab thiab khoom noj khoom haus. Ntxiv rau txiv lws suav hauv cov kaus poom thiab qos yaj ywm ua ib yam khoom siv ua kom cov nqaij tawv khov kho. Siv ua ib yam khoom siv ua kom dej khov kho thiab ua kom saj zoo rau kev ua npias. Siv tau ua ib yam khoom noj khoom haus ntxiv.
Kev tsim khoom lag luam:
1. Kev lag luam kev tsim kho: Calcium sulfate siv tau rau hauv kev lag luam kev tsim kho rau cov ntaub ntawv siv hauv kev tsim kho, cov ntaub ntawv rwb thaiv tsev, cov tshuaj pleev xim, cov ntaub ntawv txhawb nqa, thiab lwm yam. Calcium sulfate whiskers muaj kev sib txhuam zoo, kev txuag cua sov, rwb thaiv tsev kub, kev tiv thaiv hluav taws, rwb thaiv tsev tsis yog conductor thiab lwm yam khoom, thiab tuaj yeem hloov asbestos ua cov ntaub ntawv sib txhuam, cov ntaub ntawv rwb thaiv tsev kub, thiab cov ntaub ntawv hluav taws kub (fire retardant). Nws yog siv ua tus neeg sawv cev thaum ntxov hauv cov khoom sib xyaw ua ke, feem ntau nrog cov koob tshuaj ntawm kwv yees li 3%, los kho lub sijhawm teeb tsa thiab sib tov thiab zom hauv cement. Thaum calcium sulfate ntxiv rau hauv cov pob zeb, nws muaj cov txiaj ntsig zoo rau lub zog thaum ntxov.
2. Kev lag luam ua ntawv: Calcium sulfate yog siv rau hauv kev lag luam ua ntawv los hloov ib feem lossis feem ntau ntawm cov pulp. Calcium sulfate nrog qhov sib piv ntawm tsawg dua lossis sib npaug rau 50 tuaj yeem siv ua cov khoom siv zoo rau ntawv, uas tuaj yeem ua rau ntau daim ntawv tsim tawm, txo kev siv ntoo, thiab pab tiv thaiv ib puag ncig thiab txo cov dej khib nyiab.
3. Kev lag luam tshuaj lom neeg: Hauv kev lag luam tshuaj lom neeg, nws tuaj yeem siv ua cov khoom siv txhawb nqa. Cov tshuaj calcium sulfate anhydrous siv tau rau hauv kev ua cov yas granulation los txhim kho lub zog ntawm cov yas me me, tiv taus kub siab, thiab txo cov nqi. Hauv kev tsim cov yas xws li polyvinyl chloride, polyethylene, propylene, thiab polystyrene, nws tuaj yeem txhim kho kev ua tau zoo ntawm ntau yam ntawm cov khoom, txhim kho qhov zoo, qhov ruaj khov, qhov tiav ntawm qhov chaw, lub zog tensile, lub zog khoov, qhov khoov elastic modulus thiab qhov kub thiab txias deformation, thiab txo cov khoom siv hnav. Raws li asphalt filler, nws tuaj yeem ua rau qhov taw tes mos ntawm asphalt ntau ntxiv.
Kev Ua Liaj Ua Teb:
Calcium sulfate siv tau ua chiv hauv kev ua liaj ua teb kom txo cov av alkalinity thiab txhim kho kev ua tau zoo ntawm av.
Tshuaj kho mob:
Calcium sulfate muaj ntau yam kev siv hauv kev lag luam tshuaj. Nws tuaj yeem siv los npaj cov tshuaj thiab muab cov khoom xyaw thiab cov khoom tsim nyog rau cov tshuaj. Tsis tas li ntawd, calcium sulfate kuj tseem siv los ua cov ntsiav tshuaj kom ntseeg tau tias cov ntsiav tshuaj ruaj khov thiab ua haujlwm tau zoo. Tib lub sijhawm, nws kuj tseem ntxiv rau cov tshuaj txhuam hniav kom txhim kho cov khoom xyaw thiab kev ua haujlwm ntawm cov tshuaj txhuam hniav. Cov ntawv thov no qhia txog qhov tseem ceeb ntawm calcium sulfate hauv kev lag luam tshuaj, muab cov khoom xyaw tseem ceeb thiab cov khoom rau cov khoom lag luam tshuaj.
