Umcu wobhedukwayeumcu wobhedu onelothezizinto ezimbini eziqhelekileyo zobhedu lwe-alloy strips, umahluko ophambili ulele ekubunjweni, ukusebenza kunye nokusetyenziswa.
Ⅰ. Ukuqamba
1. I-Brass ikakhulu iqulunqwe ngobhedu (Cu) kunye ne-zinc (Zn), kunye nomlinganiselo oqhelekileyo we-60-90% yobhedu kunye ne-10-40% ye-zinc. Amanqaku aqhelekileyo aquka i-H62, i-H68, njl.
2. Ubhedu olukhokelayo luyi-alloy-zinc alloy ene-lead (Pb) eyongeziweyo, kwaye umxholo okhokelayo udla ngo-1-3%. Ukongeza kwilothe, inokuthi iqulethe ixabiso elincinci lezinye izinto, ezifana nentsimbi, i-nickel okanye i-tin, njl. Ukongezwa kwezi zinto kunokuphucula ngakumbi ukusebenza kwe-alloy. Amanqaku aqhelekileyo aquka HPb59-1, HPb63-3, njl.
II. Iimpawu zokusebenza
1. Iimpawu zoomatshini
(1)Ubhedu: Ngokutshintshwa komxholo we-zinc, iimpawu zomatshini zihluke. Xa umxholo we-zinc ungadluli i-32%, amandla kunye neplastiki yanda ngokunyuka kwe-zinc content; emva kokuba umxholo we-zinc udlula i-32%, iplastiki yehla ngokukhawuleza, kwaye amandla afikelela kwixabiso eliphezulu kufuphi nomxholo we-zinc we-45%.
(2)Ubhedu olukhokelayo: Inamandla alungileyo, kwaye ngenxa yobukho belothe, ukuchasana kwayo kokugqoka kungcono kunobhedu oluqhelekileyo.
2. Ukucubungula ukusebenza
(1)Ubhedu: Ineplastikhi elungileyo kwaye inokumelana nokusetyenzwa kushushu nokubanda, kodwa iqhelekile kwi-brittleness yobushushu obuphakathi ngexesha lokusetyenzwa okushushu njengokubumba, ngokubanzi phakathi kwe-200-700 ℃
(2)Ubhedu olukhokelayo: Inamandla alungileyo, kwaye ngenxa yobukho belothe, ukuchasana kwayo kokugqoka kungcono kunobhedu oluqhelekileyo. Imo ekhululekileyo yelothe yenza ukuba idlale indima yokunciphisa ukungqubana ngexesha lenkqubo yokukhuhlana, enokunciphisa ngokufanelekileyo ukuguga.
3. Iimpawu zomzimba kunye neekhemikhali
(1) Ubhedu: Ine-conductivity elungileyo yombane, i-thermal conductivity kunye nokumelana nokubola. Idleka ngokucothayo kwiatmosfera kwaye ayikhawulezi kakhulu kumanzi acocekileyo acocekileyo, kodwa idleka ngokukhawuleza kancinci emanzini olwandle. Emanzini aqukethe iigesi ezithile okanye kwiindawo ezithile ze-acid-base, izinga lokubola liya kutshintsha.
(2) Ubhedu olukhokelwayo: I-conductivity yayo yombane kunye ne-thermal ingaphantsi kancinane kunobhedu, kodwa ukuxhathisa kwayo kwe-corrosion kufana nobhedu. Kwezinye iindawo ezithile, ngenxa yempembelelo yelothe, ukuxhathisa kwayo kokubola kunokubonakala ngakumbi.
3. Izicelo
(1)Imicu yobheduzisebenza kakhulu kwaye zifanelekile kwiziganeko ezahlukeneyo, ngakumbi ezo zifuna ukubunjwa okulungileyo kunye nomgangatho ophezulu.
1) Ishishini le-elektroniki kunye nombane: izihlanganisi, iitheminali, iikhava zokukhusela, njl.
2) Umhlobiso wezakhiwo: izibambo zomnyango, imichilo yokuhlobisa, njl.
3) Ukwenziwa koomatshini: iigaskets, imithombo, iisinki zobushushu, njl.
4) Izixhobo zemihla ngemihla: iiziphu, amaqhosha, njl.
(2)Umcu wobhedu okhokelayoinomsebenzi ogqwesileyo wokusika kwaye ilungele ukwenziwa komatshini ngokuchanekileyo, kodwa ingqwalasela kufuneka ihlawulwe kwimiba yendalo kunye nempilo yelothe. Kwiinkqubo zamanzi okusela kunye neendawo ezineemfuno eziphakamileyo zokusingqongileyo, kucetyiswa ukuba usebenzise i-lead-free brass strip.
1) Amalungu achanekileyo: iinxalenye zokubukela, iigiya, iivalve, njl.
I-2) Izixhobo ze-elektroniki: i-high-precision connectors, ii-terminals, njl.
3) Ushishino lweemoto: iindawo zenkqubo yamafutha, izindlu zenzwa, njl.
