1. Izinto zokugquma
(1) Amandla okubopha ee-solders ezininzi ezisetyenziswa rhoqo kwi-brazing yobhedu neyobhedu aboniswe kwitheyibhile 10.
Itheyibhile 10 amandla eejoyinti ezifakwe isinyithi zobhedu kunye nobhedu
Xa kusenziwa ibrashi yobhedu nge-tin lead solder, i-non-corrosive brazing flux efana ne-rosin alcohol solution okanye i-active rosin kunye ne-zncl2+nh4cl aqueous solution inokukhethwa. Le yokugqibela ingasetyenziselwa ibrashi yobhedu, ibronze kunye ne-beryllium bronze. Xa kusenziwa ibrashi yobhedu lwe-aluminium, ibronze ye-aluminium kunye ne-silicon brass, i-brazing flux ingaba yisisombululo se-zinc chloride hydrochloric acid. Xa kusenziwa ibrashi yobhedu olumhlophe lwe-manganese, i-injection agent ingaba yisisombululo se-phosphoric acid. Isisombululo samanzi se-zinc chloride singasetyenziswa njenge-flux xa kusenziwa ibrashi nge-lead based filler metal, kwaye i-fs205 flux ingasetyenziswa xa kusenziwa ibrashi nge-cadmium based filler metal.
(2) Xa kusenziwa ibrazing copper ngeentsimbi kunye neefluxes zebrazing filler, kungasetyenziswa iintsimbi zesilivere kunye neentsimbi ze-copper phosphorus filler. I-silver based solder yeyona solder isetyenziswa kakhulu ngenxa yokuba inyibilika kakuhle, iyakwazi ukucutshungulwa kakuhle, iipropati ezilungileyo zoomatshini, umbane kunye nobushushu. Kwizinto zokusebenza ezifuna i-conductivity ephezulu, kufuneka kukhethwe i-b-ag70cuzn solder enomxholo wesilivere ophezulu. Kwi-vacuum brazing okanye i-brazing kwi-atmosphere protective furnace, kufuneka kukhethwe i-b-ag50cu, i-b-ag60cusn kunye nezinye izinto zebrazing ezingenazo izinto eziguquguqukayo. Iintsimbi zebrazing filler ezinomxholo wesilivere ophantsi zixabiso eliphantsi, zinobushushu obuphezulu bebrazing kunye nokuqina okubi kwamalungu ebrazing. Zisetyenziselwa ikakhulu i-brazing copper kunye nee-alloys ze-copper ezineemfuno eziphantsi. Iintsimbi ze-copper phosphorus kunye ne-copper phosphorus zingasetyenziswa kuphela kwi-brazing copper kunye nee-alloys zayo ze-copper. Phakathi kwazo, i-b-cu93p inokuguquguquka okuhle kwaye isetyenziselwa iindawo zebrazing ezingathwali umthwalo kwi-Electromechanical, izixhobo kunye nemizi-mveliso. Isithuba esifanelekileyo yi-0.003 ~ 0.005mm. Iintsimbi ze-Copper phosphorus silver brazing filler metals (ezifana ne-b-cu70pag) zinobunzima kunye nokuqhuba ngcono kuneentsimbi ze-copper phosphorus brazing filler metals. Zisetyenziswa kakhulu kwiindawo zombane ezineemfuno eziphezulu zokuqhuba. Itheyibhile 11 ibonisa iipropati zeendawo zokudibanisa zezixhobo ezininzi eziqhelekileyo zokufaka i-brazing ezisetyenziselwa ukufaka i-brazing copper kunye ne-bronze.
