Dab tsi yog Mapp Gas?
MAPP roj yog ib qho dej sib xyaw ntawm ntau yam roj carbon dioxide, zoo MAPP GAS raws Propylene, Propane thiab Dimethyl Ether mixtures, Nws ua rau lub qhov kub thiab txias (2, 976 centigrade, 198 0 f) ob qho tib si rau acetylene thaum hlawv hauv cov pa oxygen. Lub nkev siab kub tso rau hauv nws cov nplaim hluav taws xob (lub khob sab hauv) (15, 445kJ / m3), qis qeeb dua li acetylene (18, 890KJ / m3) thiab ntau dua li ntawm propane (10, 433KJ / m3). Nws cov nplaim hluav taws xob (sab nraud) kuj muab tawm cua kub tawm, zoo ib yam li cov hluav taws roj zeb thiab roj.
Nws zoo tagnrho rau kev ua haujlwm lossis hnyav siv thiab txiav hlau thiab hlau. kuj tsim rau brazing, soft soldering, cua sov, shrinking thiab xim stripping.
MAPP roj muab cov khoom zoo ntawm cov nplaim acetylene nrog ib qho hluav taws xob ntau dua. Nws kub hnyiab dua hluav taws roj thiab hluav taws xob, thiab nws tuaj yeem hlawv txuas mus ntev li 3 teev nyob rau hauv kev ua haujlwm. Lub vuam kub muaj peev xwm ncav cuag li ntawm 1350 centigrade thiab qhov ntsuas kub tau muaj peev xwm ncav cuag li ntawm 1300 centigrade nyob rau hauv kev mob nkeeg.
