1, Yintoni intsimbi engatyiwayo?
Intsimbi engatyiwa luhlobo lwentsimbi.Insimbi ibhekisela kwintsimbi equkethe ngaphantsi kwe-2% yekhabhoni (c), kunye nentsimbi engaphezu kwe-2%.Izinto ze-alloy ezifana ne-chromium (CR), i-nickel (Ni), i-manganese (MN), i-silicon (SI), i-titanium (TI) kunye ne-molybdenum (MO) yongezwa kwintsimbi kwinkqubo yokunyibilikisa ukuphucula ukusebenza kwentsimbi kunye yenza ukuba intsimbi ibe ne-corrosion resistance (oko kukuthi akukho rust), nto leyo esihlala siyibiza ngokuba yintsimbi engatyiwayo.Umzekelo, iimveliso zethu zentsimbi engenasici:iibhanjo, isiphelo sendlu ejikelezayo,iiclamps zendlu,ukukhupha okuninzi, njl.
2, Kutheni intsimbi engatyiwayo irusa?
Insimbi engenasici inamandla okuxhathisa i-oxidation ye-atmospheric - ukuxhathisa umhlwa, kwaye ikwazi ukuxhathisa i-corrosion kwindawo equkethe i-asidi, i-alkali kunye netyuwa, oko kukuthi, ukuxhathisa ukubola.Nangona kunjalo, ukuxhathisa kwe-corrosion yensimbi kuyahluka kunye nokwakheka kweekhemikhali, imeko edibeneyo, imeko yenkonzo kunye nohlobo oluphakathi kokusingqongileyo.
Insimbi engenasici yifilimu ebhityileyo kakhulu, eyomeleleyo kwaye ecolekileyo yechromium etyebileyo yeoksidi (ifilimu ekhuselayo) eyenziwe kumphezulu wayo ukuthintela iiathom zeoksijini ukuba zingaqhubeki nokungena kunye ne-oxidize, kwaye zifumana ukuxhathisa ukubola.Nje ukuba ifilimu yonakaliswe ngokuqhubekayo ngesizathu esithile, iiathom zeoksijini ezisemoyeni okanye ulwelo ziya kungena ngokuqhubekayo okanye iiathom zentsimbi ezikwintsimbi ziya kuhlala zihlukana, zenze i-iron oxide ekhululekileyo, kwaye umphezulu wesinyithi uya konakala ngokuqhubekayo.Zininzi iindlela zomonakalo kwesi sigqubuthelo sobuso, kwaye oku kulandelayo kuqhelekile kubomi bemihla ngemihla:
1. Uthuli oluqukethe ezinye izinto zetsimbi okanye iziqhotyoshelo zeengqungquthela zetsimbi ezingafaniyo zigcinwa phezu kwendawo yensimbi engenasici.Kumoya ofumileyo, i-condensate phakathi kweziqhotyoshelo kunye nensimbi engenasici idibanisa kwi-cell cell, ibangela ukusabela kwe-electrochemical kunye nokonakalisa ifilimu ekhuselayo, ebizwa ngokuba yi-electrochemical corrosion.
2. Iijusi ze-Organic (ezifana neemelon kunye nemifuno, isuphu ye-noodle kunye ne-phlegm) ibambelela kumphezulu wensimbi engenasici.Phambi kwamanzi kunye neoksijini, benza i-asidi ye-organic, eya kutshabalalisa isinyithi ixesha elide.
3. Umphezulu wensimbi engenasici unamathele nge-asidi, i-alkali kunye nezinto zetyuwa (ezifana namanzi e-alkali kunye novavanyo lokutshiza lwamanzi ekalika lokuhombisa udonga) ukubangela ukubola kwendawo.4. Kumoya ongcolileyo (i-atmosphere equkethe isixa esikhulu se-sulfide, i-oxide kunye ne-hydrogen oxide), xa udibana namanzi adibeneyo, i-asidi ye-sulfuric, i-nitric acid kunye ne-acetic acid amanqaku e-acetic acid aya kwenziwa, okubangela ukubola kweekhemikhali.
3, Indlela yokujongana namabala erusi kwintsimbi engenasici?
a) Indlela yekhemikhali:
Sebenzisa i-pickling paste okanye isitshizi ukuncedisa iindawo ezirusayo ukuba ziphinde zidlule kwaye zenze ifilimu ye-chromium oxide ukubuyisela ukuxhathisa ukubola.Emva kokukhetha, kubaluleke kakhulu ukuhlamba ngamanzi acocekileyo ngokufanelekileyo ukususa zonke izinto ezingcolileyo kunye neentsalela ze-asidi.Emva kwalo lonke unyango, sebenzisa izixhobo zokupolisha kwakhona kwaye utywine nge-wax yokupolisha.Kwabo banendawo yokurusa encinci ekuhlaleni, umxube we-1: 1 wepetroli kunye ne-oyile ye-injini ungasetyenziselwa ukosula iindawo zerusi ngeragi ecocekileyo.
b) Indlela yoomatshini:
Ukucoca uqhushumbo, ukudutyulwa kweglasi okanye amasuntswana e-ceramic, ukutshabalalisa, ukuxukuxa kunye nokupolisha.Kunokwenzeka ukucima ukungcola okubangelwa yizinto ezikhutshwe ngaphambili, izinto zokupholisa okanye izinto zokutshabalalisa ngeendlela zoomatshini.Zonke iintlobo zongcoliseko, ingakumbi amasuntswana entsimbi angaphandle, anokuba ngumthombo wokudusa, ngakumbi kwindawo efumileyo.Ngoko ke, indawo ecociweyo ngoomatshini kufuneka icocwe ngokusesikweni phantsi kweemeko ezomileyo.Indlela yomatshini inokucoca indawo kuphela, kwaye ayikwazi ukutshintsha ukuxhathisa kwe-corrosion yezinto ngokwayo.Ngoko ke, kucetyiswa ukuba uphinde upholise ngezixhobo zokupholisa emva kokucoca ngoomatshini kunye nokutywinwa nge-wax yokupholisa.
