Cov yam ntxwv ntawm cov khoom tsis-asbestos kev sib txhuam
Asbestos yog cov ntxhia silicate nrog cov qauv fibrous crystalline. Nws cov fibers me me heev uas lawv tsis tuaj yeem pom ntawm qhov muag liab qab. Lawv tau yooj yim nqus tau mus rau hauv qhov ua pa qis thiab ua rau cov kab mob pneumoconiosis, mob ntsws cancer, thoracic thiab peritoneal mesothelioma, thiab lwm yam qog nqaij hlav malignant. Sau npe ua tus kabmob loj tshaj plaws los ntawm World Health Organization, ntau lub tebchaws tau txwv tsis pub siv asbestos.
Tsim lub teb chaws hauv lub ntiaj teb kev lag luam tsheb tau ua tiav kev tshawb fawb thiab txhim kho cov ntaub ntawv tsis muaj kev sib txhuam asbestos, thiab ua tiav cov ntaub ntawv tsis muaj asbestos-dawb ib nrab hlau sib txhuam, sintered hlau txhuam cov ntaub ntawv, hloov fiber ntau reinforced los yog polymer bonded kev sib txhuam cov ntaub ntawv, puas fiber ntau txhuam. Cov ntaub ntawv, Ceramic fiber ntau sib txhuam cov ntaub ntawv, thiab lwm yam, lawv cov yam ntxwv yog:
1. Tsis muaj asbestos tivthaiv, tab sis hloov fibers lossis polymers yog siv los ua cov khoom siv ntxiv;
2. Ntxiv cov khoom siv hlau los txhim kho nws cov av noo thiab lub neej;
3. Ntau yam khoom siv los yog cov khoom ntim ntxiv tau ntxiv los txhim kho kev sib txhuam ruaj khov thiab tiv thaiv kev ua kom zoo, thiab txo cov suab nrov nres thiab sib tham.
