Ua kom raug, nws muaj kev nyab xeeb zoo. Tag nrho cov nplaim taws

Ntawm no, vim li cas acetylene txaus ntshai?

Acetylene ua rau muaj kev phom sij tshwj xeeb raws li nws qhov kub hnyiab, tsis ruaj khov thiab tshwj xeeb cia thiab kev thauj mus los. Acetylene yog heev tsis ruaj khov. Kev kub siab lossis kub tuaj yeem ua rau decomposition uas tuaj yeem ua rau hluav taws kub lossis tawg.

oxy acetylene txaus ntshai npaum li cas?

Acetylene kab siab uas tshaj 15 psig yog qhov kawg KEV HLUB .
