Yuav tiv thaiv hmoov av tawg li cas
Kev tawg tuaj yeem tiv thaiv tau yog tias ob qho tib si lossis ob qho tib si ntawm cov xwm txheej Explosive Limit thiab qhov chaw ntawm qhov hluav taws xob raug zam. Hmoov txheej txheej txheej txheem yuav tsum tau tsim los tiv thaiv ob qho xwm txheej tshwm sim, tab sis vim yog qhov nyuaj ntawm kev tshem tawm tag nrho cov khoom siv hluav taws xob, kev cia siab ntau dua yuav tsum tau muab tso rau ntawm kev tiv thaiv cov hmoov tawg ntau. Qhov no tuaj yeem ua tiav los ntawm kev ua kom ntseeg tau tias cov hmoov hauv huab cua yog khaws cia qis dua 50% ntawm Lower Explosive Limit (LEL). Txiav txim siab LELs ntawm qhov ntauNyeem ntxiv…
Qhov ua rau muaj plua plav tawg thiab hluav taws kub nyhiab thaum tsim cov hmoov txheej
Cov hmoov coatings yog cov khoom siv organic zoo, lawv tuaj yeem ua rau muaj plua plav tawg. Cov plua plav tawg tuaj yeem tawg thaum cov xwm txheej hauv qab no tshwm sim tib lub sijhawm. Muaj cov khoom siv hluav taws xob tam sim no, suav nrog: (a) qhov chaw kub lossis hluav taws kub; (b) hluav taws xob tawm lossis hluav taws xob; (c) hluav taws xob hluav taws xob. Qhov concentration ntawm plua plav hauv huab cua yog nyob nruab nrab ntawm Lower Explosive Limit (LEL) thiab Upper Explosion Limit (UEL). thaum ib txheej ntawm deposited hmoov txheej los yog ib tug huab los rau hauv kev sib cuag nrog ib tugNyeem ntxiv…
