Kev kho yog tsim los ntawm kev ntxiv cov pa ntau dua lossis tsawg dua rau acetylene nplaim taws . Cov nruab nrab nplaim taws yog nplaim taws feem ntau siv thaum twg vuam los yog txiav. Cov welder siv tus nruab nrab nplaim taws raws li qhov pib taw tes rau tag nrho lwm yam nplaim taws kev hloov kho vim nws txhais tau yooj yim heev.

Xav txog qhov no, dab tsi yog qhov nruab nrab nplaim taws hauv vuam?

Neutral nplaim taws . Cov pa roj av nplaim taws tsis yog oxidizing los tsis txo. Nws yog ib tug nyob ntsiag to thiab huv si nplaim taws tau los ntawm kev hlawv kwv yees li 50% acetylene thiab 50% oxygen. Saib kuj Carburizing nplaim taws , Oxidizing nplaim taws , Txo Nplaim taws thiab Oxyfuel Gas Vuam.

Ib yam li ntawd, vim li cas cov nplaim hluav taws tsis zoo siv rau hauv cov pa roj av vuam vuam vias? Qhov zoo ntawm kev siv Neutral nplaim taws : Kev sib xyaw ua ke ntawm tib qhov sib npaug ntawm Oxygen thiab Acetylene muab lub hau npog rau cov hlau molten thiab tsis txhob oxidation. Cov pa roj carbon dioxide uas hloov pauv thaum txheej txheem ua raws li kev tiv thaiv roj tiv thaiv cov hlau nto.

Kuj tseem yuav paub yog, vim li cas cov nplaim nruab nrab yog cov nplaim hluav taws siv oxyacetylene feem ntau siv?

A Nruab nrab nplaim taws ua tiav thaum muaj qhov sib npaug ntawm Oxygen thiab Acetylene. A Neutral nplaim taws yog li lub npe vim nws tsis muaj tshuaj lom neeg ntawm cov hlau molten. A Neutral Oxy Acetylene Nplaim yog siv rau Vuam, Brazing thiab Nyiaj Soldering feem ntau hlau thiab yog li ntawd feem ntau laj nplaim taws siv.

Yuav ua li cas yog nruab nrab oxidising thiab txo cov nplaim taws tau nyob rau hauv lub vuam teeb?

Cov nruab nrab los yog sib npaug nplaim taws yog tau thaum sib tov teeb gas muaj kwv yees li ib ntim ntawm oxygen thiab ib ntim ntawm acetylene. Nws yog tau los ntawm kev maj mam qhib lub pa oxygen kom luv cov acetylene nplaim taws kom txog thaum pom meej meej lub khob hliav qab pom.
