Magnesium hydroxide (brucite) yog ib yam tshiab ntawm cov nplaim hluav taws kub qeeb, uas tso cov dej ntws tawm thiab nqus cov cua sov ntau thaum lub sijhawm ua kom cov cua sov ua kom txo qhov kub ntawm cov pa hauv qhov dej uas muaj nws hauv cov nplaim taws. Nws muaj qhov ua haujlwm ntawm inhibiting polymer decomposition thiab txias cov roj ua hluav taws xob ua.
Magnesium hydroxide (Brucite) yog qhov hluav taws xob halogen tsis muaj nplaim taws, uas ua rau dej los ntawm cov cua sov ua kom qhuav thiab nqus cov cua sov, thiab ua rau tsis muaj qhov xeb thiab cov khoom tsis zoo tom qab lub cev tsis muaj zog. Magnesium hydroxide tsis tsuas yog txhim kho cov cua sov ua kom qhuav ntxiv ntawm cov khoom siv ntxiv, tab sis kuj tsis ua paug rau ib puag ncig. Magnesium hydroxide tuaj yeem siv dav hauv cov nplaim hluav taws ntev thiab cov pa luam yeeb ua ntawm polypropylene, polyvinyl chloride thiab cov roj hmab uas tsis muaj ntxig. Magnesium hydroxide muaj cov cua sov ua kom zoo nkauj, uas yog qhov ua kom zoo nrawm nrawm nrawm, ua kom lub sijhawm molding sai thiab txhim kho nplaim hluav taws kom zoo. Nws tuaj yeem siv dav hauv polyester, epoxy resin, txheej txheej, khoom siv fiber ntau, polypropylene, polyacrylonitrile, polyvinyl ester, xaim, cable, ntoo, ntoo, roj hmab, pleev xim, polyvinyl chloride thiab lwm cov teb.
Cov khoom siv magnesium hydroxide (Brucite) tseem muaj cov pa luam yeeb ua kom tsis muaj pa thiab tua hluav taws. Qhov no yog vim muaj qhov ua kom muaj qhov ua rau endothermic nws nyob ntawm 332 ° C (630 ° F): Mg (OH) 2 (s) → MgO (s) + H2O (g)
Lub tshav kub nqus tau los ntawm qhov tshuaj tiv thaiv yog ua rau qhov tsis nyiam qhov kawg los ntawm kev ncua qhov tsis nyiam ntawm cov khoom sib cuam tshuam. Cov dej tso tawm mus rau cov kua roj sib kis tau yooj yim thiab ua kom cov pa oxygen tsis txhob tuaj yeem pab txhawb rau kev sib tua. Cov kev siv dav dav ntawm magnesium hydroxide ua hluav taws kub retardant suav nrog cov plastics, vov tsev, thiab txheej txheej. Lwm cov khoom siv sib tov sib xyaw uas tau siv hauv cov hluav taws zoo sib xws yog cov sib xyaw ua ke ntawm cov khoom siv ntawm Huntiteand hydromagnesite.
