1. I-brazing material
(1) Amandla okubopha amasoda amaningana avame ukusetshenziswa ethusi nethusi akhonjiswe kuthebula le-10.
Ithebula 10 lamandla ethusi namajoyinti ethusi
Lapho ubrasa ithusi nge-tin lead solder, i-flux engagqwali ye-brazing efana ne-rosin alcohol solution noma i-rosin esebenzayo ne-zncl2+nh4cl isixazululo samanzi singakhethwa.Lesi sakamuva singasetshenziswa futhi ekwenzeni ithusi, ithusi kanye ne-beryllium bronze.Lapho ubhula ithusi le-aluminium, ithusi le-aluminium nethusi le-silicon, i-brazing flux ingaba isisombululo se-zinc chloride hydrochloric acid.Lapho ubhula ithusi elimhlophe le-manganese, i-ejenti yomjovo ingaba isisombululo se-phosphoric acid.Isixazululo esinamanzi se-Zinc chloride singasetshenziswa njenge-flux lapho kubhulwa ngensimbi yokugcwalisa esekelwe kumthofu, futhi i-fs205 flux ingasetshenziswa lapho kubhulwa ngensimbi yokugcwalisa esekelwe ku-cadmium.
(2) Lapho ubhula ithusi ngezinsimbi zokugcwalisa nokuguquguquka, izinsimbi zokugcwalisa ezisekelwe esiliva nezinsimbi zokugcwalisa i-phosphorus zingasetshenziswa.I-solder esekelwe esiliva iyona esetshenziswa kakhulu i-hard solder ngenxa yephuzu layo lokuncibilika elilinganiselwe, ukucutshungulwa okuhle, izakhiwo ezinhle zemishini, ukuqhutshwa kukagesi kanye nokushisa.Ocwecweni lokusebenza oludinga ukwenziwa okuphezulu, i-b-ag70cuzn solder enokuqukethwe kwesiliva okuphezulu izokhethwa.Ukuze kufakwe i-vacuum brazing noma i-brazing esithandweni somlilo esivikelayo, i-b-ag50cu, i-b-ag60cusn nezinye izinto zokubrasa ezingenazo izinto eziguquguqukayo zizokhethwa.Izinsimbi zokugcwalisa i-brazing ezinokuqukethwe kwesiliva okuphansi zishibhile, zinezinga lokushisa eliphezulu lokubhuqa kanye nokuqina okubi kwamajoyinti abrazed.Ikakhulukazi isetshenziselwa ukubhula ama-alloys ethusi nethusi anezidingo eziphansi.I-Copper phosphorus ne-copper phosphorus silver brazing filler metals ingasetshenziselwa kuphela ukubrasa ithusi nama-alloys ayo ethusi.Phakathi kwazo, i-b-cu93p inoketshezi oluhle futhi isetshenziselwa izingxenye zokubhuqa ezingekho ngaphansi komthelela womthwalo ezimbonini ze-Electromechanical, insimbi nezimboni.Igebe elifaneleka kakhulu ngu-0.003 ~ 0.005mm.Izinsimbi zokugcwalisa i-copper phosphorus silver brazing (ezifana ne-b-cu70pag) zinokuqina okungcono kanye nokusebenza kahle kunezinsimbi zokugcwalisa i-copper phosphorus brazing.Ngokuyinhloko zisetshenziselwa amalunga kagesi anezidingo eziphezulu ze-conductivity.Ithebula le-11 libonisa izakhiwo ezihlanganyelwe zezinto ezimbalwa ezivamile zokubhula ezisetshenziselwa ukubrasa ithusi nethusi.
