Qhov ua rau muaj plua plav tawg thiab hluav taws kub nyhiab thaum tsim cov hmoov txheej

Hmoov txheej 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.

1. Tam sim no muaj cov khoom siv hluav taws xob, suav nrog: (a) qhov chaw kub lossis nplaim taws; (b) hluav taws xob tawm lossis hluav taws xob; (c) hluav taws xob hluav taws xob.
2. Qhov concentration ntawm plua plav hauv huab cua yog nyob nruab nrab ntawm Lower Explosive Limit (LEL) thiab Upper Explosion Limit (UEL).

Thaum cov txheej txheej ntawm cov hmoov txheej txheej los yog huab cua los rau hauv kev sib cuag nrog cov khoom siv hluav taws xob xws li cov uas tau teev tseg saum toj no, hluav taws yuav tawg. Qhov hluav taws kub hauv cov hmoov txheej txheej yuav ua rau muaj plua plav tawg yog tias cov khoom siv hluav taws kub tau tso cai rau nkag mus rau hauv cov khoom siv, xws li cov khoom siv plua plav, lossis yog cov khoom siv hluav taws xob puas tsuaj.
