Cov hnab khib nyiab tuaj yeem tuav zaub mov

Cov khoom siv raw rau kev ua cov hnab khib nyiab tsis yog tsuas yog cov khoom yas xwb, tab sis kuj yog cov khoom siv sib txuam, suav nrog cov xim masterbatch. Cov khoom yas yog cov khoom siv polymer sib xyaw ua ke, thiab lawv qhov kev ruaj ntseg yog nyob rau hauv "txog taw tes". Thaum ntsib cov acids uas muaj zog los yog kub siab, cov tshuaj lom neeg thiab lub cev tuaj yeem tshwm sim. Tshwj xeeb tshaj yog rau cov hnab khib nyiab ua los ntawm cov yas siv dua tshiab, cov ntaub ntawv qhia tias benzo (a) pyrene hauv cov yas tuaj yeem ua rau mob qog noj ntshav. Yog li cov hnab khib nyiab tsis tuaj yeem siv los tuav cov zaub mov, tshwj xeeb tshaj yog thaum sib cuag ncaj qha nrog cov zaub mov siav lossis kub!
Yog tias nws yog lub hnab khib nyiab tsim nrog cov khoom siv tshiab, nws tuaj yeem thauj khoom ib ntus yog tias tsis tso cai rau lub sijhawm ntawd. Tom qab tuaj txog ntawm qhov chaw, nws yuav tsum tau muab tshem tawm sai li sai tau. Qee cov tuam txhab siv cov khoom siv tshiab los tsim cov hnab khib nyiab hauv chav ua noj, uas tsis muaj xim, tsis muaj ntxhiab, nrog zoo toughness thiab yooj yim rau siv. Nws kuj tseem ua tau rau cov neeg siv los tuav cov khoom uas tsis yog khib nyiab. Xwb, nws tuaj yeem siv los tuav cov khoom noj uas twb tau ntim lawm. Tab sis nws tsis pom zoo kom siv nws ntev.
