Pom zoo nyiaj raws li Brazing Paste

Lus piav qhia luv luv:

NMT brazing pastes muaj cov khoom siv hlau alloy hauv cov hmoov nplej thiab qhov twg tsim nyog cov flux.Cov khoom no tau tuav ua ke nyob rau hauv ib qho kev muab tshuaj txhuam los ntawm kev tsim tshwj xeeb hauv kev sib khi.Cov khoom kawg yog kev cai ua brazing lossis soldering tov uas tuaj yeem muab cov txiaj ntsig tshwj xeeb.Nyob rau hauv tshwj xeeb brazing thiab soldering pastes yog siv nyob rau hauv ntau lawm qhov twg yuav tsum tau los tsim ib tug loj tus naj npawb ntawm cov pob qij txha.

MMT Brazing muab tshuaj txhuam yog tsuas yog siv rau kev sib dhos ntawm cov khoom siv hluav taws xob tsawg, thiab cov khoom siv brazing haum raug xaiv rau cov khoom siv tsis siv raws li cov txheej txheem vuam sib txawv.

Product Detail

Silver Base Brazing Paste Daim Ntawv Thov

Silver brazing yog cov txheej txheem sib koom ua ke uas yog cov hlau tsis muaj hlau, cov hlau yog rhuab mus rau melting kub (siab tshaj 800 ° F) thiab muab faib nruab nrab ntawm ob los yog ntau tshaj qhov ze-fitting qhov chaw los ntawm capillary attraction.

Cov khoom tseem ceeb ntawm cov nyiaj brazing paste muaj xws li nyiaj hmoov, vuam tus neeg sawv cev thiab pab pawg.Silver hmoov yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob thiab thermal conductivity, uas tuaj yeem sau cov voids ntawm brazed me ntsis thiab yaj ntawm qhov kub thiab txias.Tus neeg sawv cev vuam siv los ntxuav thiab tshem tawm cov oxide txheej thiab txhawb kev sib txuas ntawm cov ntsiab lus brazed.Lub luag hauj lwm ntawm additives yog los txhim kho vuam zoo, txo oxidation thiab txhim khu lub zog thiab kev ntseeg siab ntawm brazed kev twb kev txuas.

Muaj feem xyuam rau cov nyiaj, nyiaj thiab tooj liab thiab tooj liab alloys;Tsawg carbon steel, tsis tshua muaj hlau alloy, stainless hlau, kub nickel puag alloy, refractory hlau thiab txhua yam ntawm hluav taws xob tiv tauj cov ntaub ntawv brazing.
