Nws yuav tsum siv ob peb feeb rau lub yas rau yaj . Tab sis nco ntsoov, melting plastics yuav tsim cov ntxhiab tsw uas tuaj yeem tsim teeb meem yog tias nqus tau. Nco ntsoov yaj lawv nyob rau hauv ib qho chaw zoo ventilated.

Khaws qhov no rau hauv kev xav, qhov kub ntawm cov fwj yas yaj yog dab tsi?

ruaj khov Cov yas Ntawm 6 feem ntau siv dua tshiab yas , plaub tuaj yeem tiv taus kub ntawm 100 ° C (212 ° Fahrenheit) lossis siab dua. Raws li Machinist Materials, polyethylene terephthalate - PET, lossis recyclable 1 - muaj yaj taw tes ntawm 255 degrees Celsius (491 degrees Fahrenheit).

Tsis tas li ntawd, Melting yas puas muaj tshuaj lom? Thaum twg yas yog hlawv, nws tso tawm txaus ntshai tshuaj xws li hydrochloric acid, sulfur dioxide, dioxins, furans thiab hnyav hlau, raws li zoo raws li particulates.
