Muaj ntau chav kawm ntawm cov khoom sib txuas uas muaj txiaj ntsig zoo li nplaim hluav taws.Thaum tam sim no ib feem me me ntawm lub lag luam loj no, Magnesium Hydroxide tau ntxim nyiam vim nws qhov kev ua tau zoo, tus nqi, qis corrosiveness, thiab tsis muaj tshuaj lom.Kev lag luam tam sim no rau magnesium hydroxide nyob rau hauv cov nplaim hluav taws yog kwv yees li kaum lab phaus hauv ib xyoos, nrog lub peev xwm kom dhau peb caug lab phaus hauv ib xyoos nyob rau yav tom ntej.
Mg (OH) 2 yog siv los ua FR hauv kev lag luam rooj tog siv hauv Tebchaws Meskas thiab hauv cov rooj tog kev lag luam thiab chaw nyob hauv tebchaws United Kingdom (Fire Retardant Chemicals Association 1998).Qhov ruaj khov ntawm Mg (OH) 2 ntawm qhov kub siab tshaj 300 ° C tso cai rau nws muab tso rau hauv ntau lub polymers (IPCS 1997).Cov ntaub ntawv lag luam-ntim luam tawm xyoo 1993 qhia tias kev siv Mg (OH) 2 nce ntxiv raws li FR.Txog 2,000 thiab 3,000 tons ntawm Mg (OH)2 tau muag raws li FR hauv Tebchaws Meskas hauv xyoo 1986 thiab 1993, raws li (IPCS 1997).
Magnesium hydroxide (Mg (OH) 2), yog cov kua qaub- thiab halogen-dawb nplaim retardant rau ntau yam yas.Magnesium hydroxide muaj 100oC siab dua decomposition kub tshaj ATH, tso cai rau ib tug siab ua hauj lwm kub nyob rau hauv compounding thiab extruding cov yas.Tsis tas li ntawd, magnesium hydroxide adsorbs ntau zog thaum lub sij hawm decomposition.
Magnesium hydroxide ua raws li cov nplaim hluav taws kub thiab cov pa luam yeeb hauv cov yas feem ntau yog tshem tawm cov cua sov los ntawm cov yas thaum nws decomposition rau hauv magnesium oxide thiab dej.Cov dej vapor uas yog generated dilutes roj mov rau cov nplaim taws.Cov khoom decomposition insulate cov yas los ntawm tshav kub thiab tsim char uas impedes cov ndlwg ntawm tej nplaim taws gases.
Rau cov nplaim hluav taws kub hnyiab tau muaj txiaj ntsig zoo hauv cov khoom siv plastics, nws yuav tsum tsis txhob degrade lub cev ntawm cov yas.Nyob rau hauv ib tug raug hloov tau yooj yim hlau PVC formulation, ZEHUI CHEM ' tau pom me ntsis txhim kho lub cev lub cev ntawm PVC formulation piv rau ATH thiab kev sib tw, qib siab magnesium hydroxide.
