Cov txheej txheem ntau lawm ntawm cov kauv vuam yeeb nkab yog qhov yooj yim, qhov kev ua tau zoo yog qhov siab, thiab cov nqi tsim khoom kuj tsawg. Yog li ntawd, cov kauv steel yeeb nkab tau tsim nyob rau hauv ntau qhov kev lag luam. Yuav ua li cas rau welding?
Ua ntej siv cov kauv steel yeeb nkab, nws yog ib qho tsim nyog yuav tsum tau siv lub deoxidant los ua deoxidation, kom cov kav hlau kav yuav txo tau tus naj npawb thiab qhov loj ntawm cov khib nyiab thaum ua haujlwm. Lub steel band yog ncaj qha welded rau hauv cov yeeb nkab steel.
Cov duab ntawm cov yeeb nkab steel tuaj yeem yog puag ncig lossis square. Qhov siab-frequency welding ntawm kauv steel yeeb nkab yog ua raws li cov cua sov vortex ntawm cov electromagnetic induction thiab AC nqi nyob rau hauv tus neeg xyuas pib. Nyob rau hauv rooj plaub, vim yog kev puas tsuaj ntawm cov zis tam sim no, cov qauv tsim ntawm magnesium alloy txia anode zoo tshaj plaws nrog rau lub sijhawm ntawm cov kav dej.
Hauv kev tsim cov kav dej kauv, kev sib raug zoo ntawm kev ruaj ntseg ntawm cov molding yog heev ze rau qhov zoo ntawm vuam. Tsuas yog los ntawm kev txhim kho qhov zoo ntawm cov molding, cov vuam zoo tuaj yeem lav tag nrho. Qhov loj thiab kev hloov ntawm qhov sib txawv ntawm cov kauv steel yeeb nkab ua cov seams yog nyob rau hauv vuam. Txhawm rau kom zoo zoo molding ntawm vuam ntawm kauv steel yeeb nkab, mus rau ib tug tej yam melting qhov tob, nws yuav tsum tau uniformly raws li qhov sib txawv ntawm cov hlau phaj. Txawv vuam specifications yuav tsum tau saws.
Nyob rau hauv lub kauv yeeb nkab, vim lub crescent khoov thiab "S" khoov ntawm lub steel siv, lub unevenness ntawm qhov sib txawv ntawm cov molding seams yog ib qho nyuaj, uas coj teeb meem rau lub vuam, ua rau lub vuam seam qhov tob thaum hloov, thaum tsim. seam yog xoob, cov welds yog sib sib zog nqus thiab txo; Thaum lub molding seam yog nruj, cov welds yog molten kom me me thiab qhov seem qhov siab nce. Thaum loosening, txo qhov vuam specification, thiab nce qhov vuam specification thaum lub sib sau yog nruj.
Txoj kev tiv thaiv corrosion ntawm cov kav dej nrog cov kav dej kauv kuj pib los ntawm ib qho ntawm cov txheej txheem. Cov khoom siv hlau uas tau muab tso rau hauv cov kav hlau uas muaj cov kav hlau uas muaj kauv hlau yog siv los txuas nrog cov kav hlau kauv hlau. Yog li ntawd, zoo li no yuav tsis tshwm sim. Lub raj yuav tsum tau txais cov txheej txheem los tiv thaiv corrosion uas muab cov txheej txheem tiv thaiv corrosion thiab kev txi anode. Rau lwm cov kav dej uas tsis yog lub cev tseem ceeb nrog lub siab qis, cov txheej txheem anticorrosive feem ntau yog siv ncaj qha.
Tam sim no, muaj peb txheej ntawm PE cov qauv siv feem ntau siv hauv cov kav dej faus. Epoxy resin hmoov (FBE), thee coke porcelain xim, epoxy thee asphalt thiab PE daim kab xev. Tus nqi. Tab sis nws yuav tsum tau muab sau tseg tias thaum cov av resistivity siab dhau lawm thiab cov kav dej tiv thaiv hla dej, nws tsis pom zoo kom siv cov anodes ntawm kev txi. Txoj kev sib txawv los tiv thaiv corrosion muaj qhov sib txawv anticorrosive zoo thiab cov nqi. . Lub hom phiaj sib txawv thiab qhov chaw sib txawv thiab cov roj sib txawv hauv nws, ua tiav xav txog txoj kev tiv thaiv corrosion thiab cov nqi tiv thaiv.
