Isampuli isiliva Yintoni

Nangona ukuba sele baqhele ukuqikelela ixabiso yonxulumano zesilivere angaphantsi kakhulu ngaphezu koko eyenziwe ngegolide, isiliva, ngokuxhomekeke ingxubevange, umsebenzi isilivere iimvavanyo ibize igolide ngakumbi. Kakade ke, kwezinye iimeko, indima ebalulekileyo idlalwa luyasebenza mayana othengisa, kuba abanye afakwe ubuchule yokwenza izacholo ayinako yayiphindwa xa ukusebenza ngegolide. Kodwa ke inkoliso indima ebalulekileyo eyadlalwa isampulu.

Kudla izacholo singenziwa luyiyo izinyithi amanene, ekubeni inani elithile nezingalunganga. Umzekelo, isilivere esulungekileyo - kuyinto material ethambileyo kakhulu, ngoko ke yenziwa i intsila kongezwe imali encinane obhedu ukuphucula amandla ayo. Umxholo ngobhedu ingxubevange kwisampulu imisela ipesenti zesilivere nokucoceka. Kwiimeko ezinqabe kakhulu kwi "ukomelezwa" zesilivere, ezinye iintsimbi asetyenziswa, ongeziweyo ezisetyenziswa nickel, aluminiyam, izinc kunye isiqalelo esithambileyo esimhlophe. Kodwa kwiimeko ezininzi kuba izinto ezingundoqo ingxubevange yesilivere lubhedu.

Kule isampuli eliphezulu zesilivere ngobhedu zikhoyo ngezixa ezincinane, zinencasa umthunzi emhlophe, Tint umbala otyheli kuphela silver isampulu iphantsi. Kodwa ingxubevange kuyabiza kakhulu zesilivere luthathwa kuba ingxubevange kunye isiqalelo esithambileyo esimhlophe, yaye ngokufuthi kwezi meko ezenziwe kulo zesiliva ezixabisa ngaphezu kwegolide. Kumazwe amaninzi ehlabathini ukubhekisela isampuli yesilivere 'ukuqalisa ngoku ngesixokelelwano metric. Xa kuboniswa kule inombolo isampuli metal okuyingxenye elunge eliwaka iindawo (iiyunithi ubunzima) ingxubevange. Ubuninzi ngokuba ubucwebe yi 960 zesilivere, kunye nalo, kukho 925, 916, 875, 800 no-750-I. Igosa Russian bafumanisa ukuba xa izacholo unalo ezinomthamo wentsimbi ophucukileyo iisampuli ngaphantsi kwama-800, nto leyo umiselwa ubuncinane, ngoko ke kule kwenzeka phantsi karhulumente kunye nebala ayaqondwa sele njengoko iimveliso ezenziwe Metal.

Ezi mveliso amaninzi zifumaneka kubomi bemihla ngemihla, ezo zisetyenziswa ukuba imithombo, nezikhonkwane, solder njalo eziphathekayo. Ukulungiselela le njongo ingxubevange Isilivere iisampuli 720. Kodwa kumazwe aseYurophu kunokwenzeka rhoqo ukuhlangabezana amancinci izincedisi impahla ezazibajikelezile 750. Nangona kunjalo, lo ucazululo ixhaphakileyo eYurophu ithathwa 925-I, ngaphandle eFransi, apho 800-I kuxhaphake kakhulu.

Isampulu liphezulu 960 esetyenziselwa mveliso le afakwe izacholo mhle, ezifana kuphela likuvumela ukuba ulungise ingxubevange yesilivere yalo zixhobo leyo ke baziinkosi ukwenza amanani openwork. Ayikho enye metal ezixabisekileyo ezifana amathuba esingenayo. Ukunika iimveliso afakwe amandla zenziwe enziwa isiqalelo esithambileyo esimhlophe, ingxubevange yesilivere, ukusuka apho ifunyenwe esihle openwork afakwe (ipatheni ntambo, nto leyo ibonakala ngokucacileyo lomzobo). Noko ke, kule imeko, ixabiso wafumana imihombiso na ukunyuka ingxubevange kakhulu.

Nathi kufuneka nokuba zijolise ukuvelisa njani Stars zokucoca. isidingo sabo kuqala ahlambe ngamanzi ashushu nesepha uze ukunyhibhela gruel yekalika, zifakwe ammonia engamanzi. Xa yomile lasebenza umxube, imveliso kufuneka ngocoselelo soyalazwa ngamanzi, nokuzisula owomileyo ngelaphu ethambileyo. Ukuba iimveliso zesilivere oxidized, kufuneka icocwe neqhinga zolwelo sodium sulfate. nezesiliva kufuneka zicocwe kwakunye loqobo 925, nto leyo uqobo owenziwe iintshengece zesilivere, iifolokhwe neenkamba. Ukuba zigcine zisakhazimla emva ukusetyenziswa, izitya kufuneka nkxu emanzini abilayo kunye isoda kancinane.
