Umvavanyi wokutshiza ityuwa
Ityuwa, ngokuqinisekileyo eyona khompawundi isasazwe ngokubanzi kwiplanethi, ifumaneka kuyo yonke indawo elwandle, umoya, umhlaba, amachibi kunye nemilambo.Nje ukuba amasuntswana etyuwa adityaniswe kumathontsi amancinane elulwelo, indawo yokutshiza ityuwa iye yenziwa.Kwiimeko-bume ezinjalo, phantse akunakwenzeka ukuzama ukukhusela izinto kwiziphumo zesitshizi setyuwa.Enyanisweni, isitshizi setyuwa sisesibini kuphela kwiqondo lokushisa, ukungcangcazela, ubushushu kunye nokufuma, kunye neendawo ezinothuli malunga nomonakalo koomatshini kunye neemveliso ze-elektroniki (okanye amacandelo).
Uvavanyo lwesitshizi setyuwa yinxalenye ephambili yesigaba sophuhliso lwemveliso ukuvavanya ukuxhathisa kwayo kokubola.Iimvavanyo ezilolo hlobo zahlulwe ikakhulu zibe ziindidi ezimbini: olunye luvavanyo lokuvezwa kokusingqongileyo kwendalo, oludla ixesha nolufuna umsebenzi omkhulu, kwaye ke ngoko alusetyenziswa kakhulu kwizicelo ezibonakalayo;enye luvavanyo lwemekobume yokutshizwa kwetyuwa olukhawulezileyo, apho ugxininiso lwekloridi lunokufikelela amaxesha aliqela okanye amashumi amaxesha omxholo wokutshizwa kwetyuwa kwindalo esingqongileyo, kwaye izinga lokudleka linyuka kakhulu, ngaloo ndlela lifinyeza ixesha lokufika. iziphumo zovavanyo.Umzekelo, isampulu yemveliso enokuthatha unyaka ukuba idleke kwindawo yendalo inokuvavanywa kwindawo eyenziweyo eyenziweyo eyenziweyo yokutshiza ityuwa eneziphumo ezifanayo kwisithuba nje seeyure ezingama-24.
1) Umgaqo wokuvavanya ityuwa yokutshiza
Uvavanyo lwesitshizi setyuwa luvavanyo olulinganisa iimeko zendawo yokutshiza ityuwa kwaye lusetyenziswa ngokuyintloko ukuvavanya ukuxhathisa kokubola kweemveliso kunye nezixhobo.Olu vavanyo lusebenzisa izixhobo zovavanyo lokutshiza ngetyuwa ukwenza imeko-bume yokutshiza ityuwa efana naleyo ifumaneka kwi-atmosfera yolwandle.Kwimeko-bume elolo hlobo, i-sodium chloride kwisitshizi setyuwa ibola ibe yi-Na+ ion kunye neeCluni phantsi kweemeko ezithile.Ezi ion zisebenza ngokwekhemikhali kunye nemathiriyeli yesinyithi ukuvelisa iityuwa zentsimbi ezineasidi eqinileyo.Ii-ion zentsimbi, xa zisesichengeni seoksijini, zinciphisa ukuze zenze ii-oxide zentsimbi ezizinzile.Le nkqubo inokukhokelela kwi-corrosion kunye ne-rust kunye ne-blistering yesinyithi okanye i-coating, leyo ke inokukhokelela kwinani leengxaki.
Kwiimveliso zoomatshini, ezi ngxaki zingabandakanya ukonakala kwe-corrosion kumacandelo kunye ne-fasteners, i-jamming okanye ukungasebenzi kakuhle kwamacandelo ahambayo amacandelo omatshini ngenxa yokuphazamiseka, kunye neesekethe ezivulekileyo okanye ezimfutshane kwiingcingo ezincinci kunye neebhodi zocingo eziprintiweyo, ezinokukhokelela ekuqhekekeni komlenze wecandelo.Ngokubhekiselele kwi-electronics, iipropathi zokuqhuba izisombululo zetyuwa zingabangela ukuchasana kweendawo ze-insulator kunye nokumelana nomthamo kuncitshiswe kakhulu.Ukongeza, ukuchasana phakathi kwetyuwa yokutshiza izinto ezitshabalalisayo kunye neekristale ezomileyo zesisombululo setyuwa ziya kuba phezulu kunoko kwentsimbi yokuqala, eya kwandisa ukuxhathisa kunye nokuhla kwamandla ombane kwindawo, echaphazela isenzo sombane, kwaye ngaloo ndlela ichaphazela iimpawu zombane zemveliso.
