Qhov sib txawv tseem ceeb ntawm asbestos thiab cov ntawv cement yog cov asbestos yog ib txwm tshwm sim silicate ntxhia whereas cov ntawv cement yog cov khoom tsim khoom tsim khoom tsim.
Asbestos yog cov pob zeb hauv av thiab cov cement, lossis fibro yog cov ntaub ntawv uas muaj txiaj ntsig zoo li cov khoom siv hauv tsev thiab ua los ntawm asbestos thiab cement sib tov. Ntawm no, asbestos muaj nyob rau hauv daim ntawv fibrous. Lub ntuj tshwm sim asbestos tshwm sim raws li ntev thiab nyias fibrous crystals.
Asbestos yog dab tsi?
Asbestos yog ib txwm tshwm sim silicate ntxhia. Muaj rau daim ntawv ntawm cov ntxhia no; peb sau npe ua asbestos. Tsis tas li ntawd, cov khoom no tshwm sim raws li ntev, nyias fibrous crystals. Txhua yam ntawm cov fibers no muaj cov fibers. Cov fibrils no yog nyob rau hauv microscopic scale. Ntxiv mus, cov fibrils yooj yim txav mus rau qhov chaw ntawm kev puas tsuaj lossis los ntawm lwm cov txheej txheem. Cov txheej txheem siv lead ua ntawm cov pob zeb no tuaj yeem piav qhia tias yog orthorhombic lossis monoclinic vim tias ob qho tib si cov qauv no tuaj yeem pom. Cov ntxhia no muaj cov tsos dawb-grey. Crystal cwj pwm yog amorphous, thiab cleavage yog prismatic. Qhov tawg ntawm asbestos yog fibrous. Nws muaj ib tug txhob lo lo ntxhuav, thiab cov ntxhia streak yog dawb.
Daim duab 01: Pom ntawm Asbestos Fibrils
Asbestos tau dav siv los ua cov khoom siv hauv tsev, feem ntau hauv vov tsev. Txawm li cas los xij, nws paub zoo txog nws txoj kev noj qab haus huv. Yog li ntawd, nyob rau hauv ntau lub teb chaws, cov khoom no raug txwv thiab tsis pub siv los ua cov khoom siv hauv tsev. Nws feem ntau yog vim qhov nqus ntawm fibrils ntawm asbestos tuaj yeem ua rau mob carcinogenic xws li asbestosis thiab mob ntsws cancer. Vim li no, ntau yam khoom siv los hloov pauv asbestos.
Cement Sheet yog dab tsi?
Cov ntawv cement yog cov khoom siv tsim los ntawm asbestos fibers. Nws yog qhov tseem ceeb tshaj plaws raws li cov khoom siv vov tsev. Tsis tas li ntawd, cov ntawv cement muaj cov asbestos fibers thiab cement. Hauv kev tsim cov ntawv MAAs, nyias nyias, cov cement yog siv los siv asbestos los ua cov ntawv cement.
Daim duab 02: Lub Tsev nrog Asbestos Cement Sheets
Ntxiv mus, cov khoom no kuj yog ib qho zoo heev hloov rau lwm yam khoom siv hauv tsev xws li ntoo, cib, slate, pob zeb, thiab lwm yam. pwm nws ua lwm yam zoo li. Tsis tas li ntawd, lub npe ntawm cov khoom no hauv kev ua lag luam yog "fibro".
Qhov txawv ntawm Asbestos thiab Cement Sheet yog dab tsi?
cov ntawv cement yog ua los ntawm asbestos. Yog li ntawd, lawv yog ob yam khoom sib txawv. Qhov sib txawv tseem ceeb ntawm cov asbestos thiab cov ntawv cement yog cov asbestos yog cov ntxhia silicate uas tshwm sim, thaum cov ntawv cement yog cov khoom tsim khoom tsim. Tsis tas li ntawd, thaum xav txog cov khoom siv no, cov asbestos muaj cov microscopic fibrils ntawm silicate ntxhia, thaum cov ntaub ntawv cement muaj fiber ntau asbestos thiab cement.
Ntxiv mus, cov asbestos tseem ceeb rau kev tsim cov khoom siv hauv tsev, xws li fibro, tab sis cov ntaub ntawv cement tseem ceeb yog cov khoom siv hauv tsev, hloov lwm yam khoom siv hauv tsev xws li ntoo, cib, slate, pob zeb, etc.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm cov asbestos thiab cov ntawv cement.
Summary – Asbestos vs Cement Sheet
Hauv luv luv, cov ntawv cement yog ua los ntawm asbestos. Yog li ntawd, lawv yog ob yam khoom sib txawv. Txhawm rau ua kom tiav, Qhov sib txawv tseem ceeb ntawm cov asbestos thiab cov ntawv cement yog tias cov asbestos yog ib txwm tshwm sim silicate ntxhia, whereas cov ntawv cement yog cov khoom tsim khoom tsim khoom tsim.
