Ziziphi iindlela zokuchonga ubhedu olucocekileyo

1. Jonga ubulukhuni: kokukhona ukucoleka kweubheduubucwebe, kokukhona ubuthambileyo buthambile kwaye bumhlophe kwaye bugudileyo umphezulu.Abavelisi be-alloy copper bathatha amasongo obhedu malunga ne-60 grams njengomzekelo.Ukuba zitsalwa zivuliwe ngesandla, akukho u-elasticity, kwaye ubuhle babo bumalunga ne-95%.Ukuba kukho i-elasticity encinci, i-fineness i malunga ne-80% -90%;ukuba i-elasticity inkulu, i-fineness ingaphantsi kwe-70%.
2. Jonga iindiza: sika okanye usonge ubucwebe bobhedu ukuze ubone umbala weendiza.Ukuba ubucwebe buyithambile, i-stubble inzima kwaye ithambile, ibomvu kancinane, kwaye umbala umalunga ne-95%;ukuba kunzima ukugoba ngesandla, umququ umhlophe kunye negrey, okanye ubomvu kancinci, kwaye umbala umalunga ne-90%;ukuba ubunzima bumalunga ne-90% Enkulu, i-sbbles ibomvu ebomvu, i-yellow-white okanye i-gray, kwaye i-fineness malunga ne-80%;ukuba i-sbbles inzima, i-stubble ibomvu, i-yellowish, i-khaki kunye neminye imibala, kunye ne-fineness malunga ne-70%;ukuba i-lipstick imnyama, Okanye tyheli ngomnyama, kwaye ubuhle bungaphantsi kwama-60%.
3. Indlela yokugoba: i-pinch kunye nokugoba ngeminwe, umgangatho ophezulu othambileyo kwaye uguquguqukayo, kulula ukugoba kwaye akukho lula ukuphula;ukugoba okukumgangatho ophantsi kunzima, okanye akunakugoba, kwaye abanye abakwazi nokugoba ngeminwe;i-copper-clad I-fake iya kuqhekeka emva kokugoba okanye ukubethelwa ngehamile ngamaxesha ambalwa;inkohliso ayiyi kukwazi ukumelana nokugoba kwaye kulula ukuyiqhawula.Ngaba zikhona izibonelelo zempilo ezifumaneka ekunxibeni izacholo zemagnethi, ezihlala zinexabiso elibalulekileyo lobuhle.
4. Indlela yokuphosa: ubucwebe bobhedu obuphezulu, obuphonswe ebhodini, awukwazi ukutsiba phezulu, kukho isandi esithi "pop";ubucwebe bobhedu obungeyonyani okanye obuphantsi bulula, buphoswe ebhodini kwaye bugxumela phezulu kakhulu, busenza isandi Ngokulinganayo crisp.Iingcebiso ezilungileyo zokusebenza kunye nobucwebe bobhedu ziquka ukuzama iindlela ezahlukeneyo kunye nokucinga malunga nokugqiba.Ubhedu olungacocwanga lune-sheen etshintsha umbala ngokuhamba kwexesha.Iibhloko ezimbini zobhedu kunye nomsonto zinokusetyenziswa ukwenza amacici anomdla, iintsimbi zomqala, izacholo kunye nemisesane.
Ubhedu olusulungekileyo, njengoko negama lisitsho, lubhedu olunobhedu oluphezulu, kuba umbala unombala omfusa-obomvu, owaziwa ngokuba lubhedu olubomvu.Inxalenye ephambili yobhedu kunye nesilivere, kwaye umxholo ngu-99.5-99.95%.Izinto eziphambili zokungcola: i-phosphorus, i-bismuth, i-antimony, i-arsenic, i-iron, i-nickel, i-lead, i-tin, i-sulphur, i-zinc, i-oksijini, njl.
