Ib txoj hauv kev yooj yim tshaj plaws los ua cov nplaim hluav taws xob yog los ntawm kev txiav cov qauv ntawm cov yas thiab igniting nws nyob rau hauv lub fume cupboard. Cov xim ntawm cov nplaim taws, cov ntxhiab tsw thiab cov yam ntxwv ntawm kev kub hnyiab tuaj yeem ua rau muaj qhov qhia txog hom yas: 1. Polyethylene (PE) - Drips, tsw zoo li tswm ciab;

2.Polypropylene (PP) - Drips, tsw ntxhiab feem ntau ntawm cov roj cav qias neeg thiab undertones ntawm candlewax;

3. Polymethylmethacrylate (PMMA, "Perspex") - npuas, crackles, qab zib tsw ntxhiab;

4. Polyamide los yog "Nylon" (PA) - Sooty nplaim, tsw ntawm marigolds;

5. Acrylonitrilebutadienestyrene (ABS) - Tsis pob tshab, nplaim taws, tsw ntxhiab ntawm marigolds;

6. Polyethylene ua npuas ncauj (PE) - Drips, tsw tsw ntxhiab tsw qab
