Tuam Tshoj Tus Nqi Zoo CalciumAlumina Cement CAS: 65997-16-2
CalciumAlumina Cement yog cement nrog calcium calcium los yog calcium aluminium ua nws cov ntxhia tseem ceeb. Nws yog ua los ntawm ntuj txhuas los yog muaj alumina thiab calcium carbonate (limestone) raws li ib qho kev faib ua feem, uas yog tsim los ntawm kub kub los yog hluav taws xob yaj.
Cov khoom xyaw thiab pawg: CalciumAlumina Cement tuaj yeem muab faib ua aluminium calcium calcium cement (al2O3 53-72%, CAO 21-35%) thiab ntshiab aluminium calcium cement (al2O3 72-82%, CAO 19-23%) Ob pawg. Ordinary aluminium cement cement tuaj yeem muab faib ua hom hlau qis (FE2O3 <2%) thiab high-speed rail hom (Fe2O37-16%). Tsawg-rail-type aluminium-type calcium cement tuaj yeem muab faib ua alum av cement (Al2O353 ~ 56%, CAO 33-35%), aluminium -60 cement (al2O359% rau 61%, CAO 27-31%), thiab qis-calcium aluminium acid cement (Al2O3 65-70%, CAO 21. Ntshiab aluminium calcium cement tuaj yeem muab faib ua ob hom: Al2O3 72-78%) thiab ultra-high aluminium hom (Al2O3 78-85%). Tsis tas li ntawd, muaj qhov ceev thiab tawv thaum ntxov muaj zog aluminium calcium cement.CAS: 65997-16-2 Nr

Chaw tsim tshuaj paus Zoo Nqe Stearic acid CAS: 57-11-4
Stearic acid: (qib kev lag luam) Octadecanoic acid, C18H36O2, yog tsim los ntawm hydrolysis ntawm roj thiab yog siv nyob rau hauv zus tau tej cov stearate.
Stearic Acid-829 Stearic acid, Stearic acid yog cov roj fatty acid tau los ntawm cov tsiaj thiab zaub rog, cov khoom tseem ceeb ntawm cov stearic acid (C18H36O2) thiab palmitic acid (C16H32O2).
Cov khoom no yog dawb los yog dawb zoo li hmoov los yog crystalline nyuaj block, nws profile muaj microstrip luster zoo koob siv lead ua; Nws muaj ib tug me ntsis tsw zoo li roj thiab yog tasteless. Cov khoom no yog soluble hauv chloroform lossis diethyl ether, yaj hauv ethanol, yuav luag insoluble hauv dej. Lub freezing point Qhov chaw khov (Appendix Ⅵ D) ntawm cov khoom yuav tsum tsis txhob qis dua 54 ℃. Tus nqi iodine Tus nqi iodine ntawm cov khoom no (Appendix Ⅶ H) tsis ntau tshaj 4. Acid Value (Appendix Ⅶ H) ntawm cov khoom no yog li ntawm 203 mus rau 210. Stearate nkag siab nrog magnesium thiab calcium ions los tsim magnesium stearate thiab calcium stearate (dawb precipitate)
