Kev ua zaub mov
Calcium sulfate tuaj yeem siv los ua cov hmoov txhuv nplej siab (raws li diluent rau benzoyl peroxide), nrog rau kev siv siab tshaj plaws ntawm 1.5 grams ib kilogram; nws yog siv los ua coagulant hauv kev ua zaub mov. Rau kev tsim cov taum pauv, kwv yees li 14-20 grams ntawm taum pauv tau ntxiv rau cov kua mis ib liter (qhov ntau dhau yuav ua rau iab saj). Nws yog ntxiv rau cov hmoov nplej ntawm 0.15 feem pua, siv los ua cov khoom noj poov xab thiab khob noom cookie txias. Ntxiv rau txiv lws suav thiab cov qos yaj ywm hauv kaus poom ua cov ntaub so ntswg txhim kho. Brewed npias yog siv los ua ib qho hardener rau dej thiab ib qho tsw enhancer rau caw. Nws kuj tseem siv tau los ua khoom noj khoom haus ntxiv.
Muaj ntau lawm
Kev tsim kho kev lag luam: Calcium sulfate tuaj yeem siv rau hauv cov khoom siv hauv tsev, cov ntaub ntawv thermal rwb thaiv tsev, txheej txheej, cov khoom siv ntxiv, thiab lwm yam hauv kev tsim kho kev lag luam. Calcium sulfate whiskers muaj kev sib txhuam zoo, txuag hluav taws xob, rwb thaiv tsev kub, tiv thaiv hluav taws, rwb thaiv tsev tsis zoo thiab lwm yam khoom, thiab tuaj yeem hloov cov asbestos ua cov ntaub ntawv sib txhuam, cov ntaub ntawv thermal rwb thaiv tsev thiab hluav taws kub (flame retardant) cov ntaub ntawv. Raws li tus neeg sawv cev thaum ntxov muaj zog hauv cov khoom sib xyaw ua ke, qhov kev siv dav dav yog li 3 feem pua los kho lub sijhawm teeb tsa thiab sib tov hauv cov cement. Thaum calcium sulfate tov rau hauv pob zeb, nws muaj qhov pom tseeb thaum ntxov zog.
Kev lag luam ntawv: Calcium sulfate yog siv nyob rau hauv daim ntawv kev lag luam los hloov ib co los yog feem ntau ntawm cov pulp. Nws tuaj yeem siv los ua cov ntaub ntawv qib siab rau cov ntawv nrog qhov sib piv ntawm tsawg dua lossis sib npaug li 50, uas tuaj yeem ua rau cov ntaub ntawv ntau ntxiv, txo cov khoom siv ntoo, tiv thaiv ib puag ncig, thiab txo cov dej khib nyiab.
Kev lag luam tshuaj lom neeg: Hauv kev lag luam tshuaj, nws tuaj yeem siv los ua cov khoom siv ntxiv, thiab anhydrous calcium sulfate whiskers tuaj yeem siv rau hauv cov yas granulation los txhim kho lub zog ntawm cov khoom yas, kub ua hauj, thiab txo cov nqi. Hauv kev tsim cov polyvinyl chloride, polyethylene, propylene, polystyrene thiab lwm yam yas, nws tuaj yeem txhim kho kev ua haujlwm ntawm txhua yam ntawm cov khoom, txhim kho fineness, dimension stability, nto tiav, tensile zog, flexural zog, flexural modulus thiab thermal deformation kub, thiab txo cov khoom hnav. Raws li asphalt muab tub lim, nws tuaj yeem nce qhov muag muag ntawm asphalt.
Ua liaj ua teb
Calcium sulfate tuaj yeem siv ua chiv hauv kev ua liaj ua teb kom txo cov av alkalinity thiab txhim kho av kev ua haujlwm.
Tshuaj kho mob
Calcium sulfate muaj keeb kwm ntev ntawm kev siv los ua cov pob txha hloov pauv. Thaum ntxov li 1892, Dreesman siv calcium sulfate filling los kho cov pob txha tsis xws luag, thiab 6 ntawm 9 tus neeg mob tau kho tag nrho. Ntau tus kws tshawb fawb tau tshawb fawb zoo sib xws thiab ua tiav yav tom ntej, tab sis tsis muaj teeb meem cuam tshuam txog calcium sulfate tau pom. Ntau qhov kev tshawb fawb thiab kev siv tshuaj kho mob tau zoo tau pom tias calcium sulfate ceramics muaj cov yam ntxwv hauv qab no: biocompatibility zoo; biodegradable tom qab cog; osteoconductivity; zoo microporosity; tsis muaj zog.
