Metal Nosipho: Theory and Practice

ukuya ngasekhohlo Chemical kuthetha ekususeni metal ukusuka kumphezulu wayo le oxides okanye iintsalela ukubhobhoza. Loo nkqubo ibandakanya ukusetyenziswa ngesisombululo iityuwa chloride sisombululo kwealkali okanye asidi. Kungakhathaliseki ukuba yintoni hlobo arhente yemichiza ndlongondlongo asetyenziswa, lo ngasekhohlo zesinyithi kufuna isilumkiso kakhulu kunye nokuchaneka kwabantu, ekubeni izinto ezinjalo bayingozi kwaye udibana nesikhumba kunokubangela nokutsha. Noko ke, ulungiselelo eyiyo inkqubo sinako ukwenza ekhaya. Metal ngasekhohlo ivumela lokuyivelisa nantoni ibali, itekisi, ubunzulu okanye uncedo nezidanga phantse nasiphi umphandle metal. Iimveliso ukuba umphumo ezixabisa ngokwenene achithe ixesha ezamahala uhlola obu bugcisa.

Kakuhle eli inkqubo

Metal ngasekhohlo isenokuba ngokupheleleyo, nto leyo idla isetyenziselwa zokuthambisa lula kwaye buso, ukuba ngokufuthi esetyenziselwa nohombisoa bezinto. Kwimeko yokugqibela, ukukhusela iindawo nguwuphi na ngale mpatho, ebizwa ngokuba ulwe. Metal ngasekhohlo engenziwa nokuba iikhemikhali okanye galvanically. Kwimeko yokuqala imveliso ifike ukuntywiliselwa ibe isisombululo. Ixesha unyango kuxhomekeke kubunzulu ngasekhohlo ezifunwayo kunye nohlobo eziphathekayo. Emva kokuba metal ahlambe ngokupheleleyo ngamanzi abandayo, nto leyo maxa wambi i isisombululo zolwelo ye soda. Oku kwenza kube lula ukuba uqinisekise ukuba imizila acid akuyi konakalisa isiphumo.

Ethile Metal babhale

Kuye ezisetyenziswa ngamaXesha Aphakathi ngenxa nohombisoa yezixhobo nezikhali. Ebuhleni zabo iimveliso zidla enasilela ngayo indalo zezandla abanamakhono bejewellery. Ngokuba lo hlobo lonyango metal ubuso yesibini ilungileyo, oko kukuthi, indlela galvanic. Le ndlela uphepha ukuyilwa imimoya enetyhefu zabantu ezivela unyango xa imichiza, kwaye isebenza ngakumbi kuba sikwazi ukwenza imiphetho ngokucacileyo ipateni kwagxila.

ukuya ngasekhohlo galvanic practice

Ukuze ubonise italente zabo ukuze uqalise le nkqubo ekhaya, into yokuqala kukufumana umthombo ombane DC esimalunga ulingana 4-7 Volt. Ideal - amandla indlu unikezelo nge iswitshi. Ngoko kuyimfuneko ukuba zifumane i itreyi kukho izinto zokwambathisa ezikhoyo, nto leyo eya kuba electrolyte. Njengoko lo wokugqibela zingasetyenziswa isisombululo ifumile yetyuwa ngokufanayo, kodwa ngokuqhelekileyo zisetyenziselwa le njongo lichithakale sulphate. Iron isetyenziselwa zentsimbi kunye intsimbi, nobhedu - kuba ngobhedu, nobhedu nangobhedu. Le blank metal kufuna degreased engaphambili. Ukulungiselela le njongo kubhaliwe soldered ucingo lobhedu yenziwe nkxu ukuba imizuzu emi-5 ukuya nesisombululo sodium hayidroksayidi, osuke ukuya kwiqondo lobushushu 50 ° C. Emva koko, lo preform udluliselwa imizuzu embalwa ulwelo ezinomthamo-15% sulphuric acid, uze emva koko wahlamba ngokupheleleyo ngamanzi ashushu. sigaba wokulungiselela Last - ukulungiswa yemastic. Ibhokisi tin Umxube pitch, rosin kunye wax kwindawo umlinganiselo we-4: 2: 3 zinyibilike ifikelele kubunzima eyohlobo olulodwa. Xa lupholile oko, azisongele kwilinen obhityileyo kunye okuqinileyo drive yi workpiece shushu kancinane nje ixesha elide kangangoko legqunyiwe ngomaleko iyunifomu obhityileyo. Emva kwako konke oku kuye lukhuni, sebenzisa i umbala amanzi ukupeyinta ipatheni efunekayo yaye Ndolutshayela putty nesitshetshe apho kufuneka ukuba benaso-nzulu. Ngoku bayifake electrolyte ngokuthi wokufaka terminal ukuya kwipali kwaye ukuba ucingo kunye lokucutha gxotha nayiphi na into metal kwaye zinokuwehlisa kungena electrolyte. Emva kokugqitywa ngasekhohlo Unsolder wire siwabeka turpentine wafumana wobugcisa kwaye yenze kubekho nokuyifeza lokugqibela (besila nezokucoca).
