Insimbi engenasici iyaziwa ngokubanzi ngokuhlala kwayo, ukomelela kwayo, kwaye, okona kubalulekileyo, yayoukumelana nomhlwa. Le propathi iyenza ibe yimathiriyeli yokuzikhethela kumashishini angenakubalwa, ukusuka kulwakhiwo kunye nokulungiswa kokutya ukuya kwimveliso yaselwandle kunye neekhemikhali. Kodwa yintoni kanye kanye enika intsimbi engatyiwayo ukuxhathisa kwayo kumhlwa nokuthotywa? Kwaye unokuqinisekisa njani ukuba intsimbi yakho engenasici isebenza njengoko kulindelekile kwiindawo ezahlukeneyo?
Kweli nqaku, sicacisa isayensi emva kokuxhathisa umhlwa kwentsimbi engatyiwayo, iintlobo ezahlukeneyo ezikhoyo, kunye nendlela yokukhetha ibakala elifanelekileyo kwisicelo sakho esithile.
Yintoni eyenza iStainless Steel Corrosion Resistant?
Isitshixo sokuxhathisa umhlwa kwentsimbi engatyiwa silele kuyoumxholo wechromium. Zonke iintsimbi ezingenastainless ziqulathe ubuncinci be-10.5% yechromium, edibana neoksijini esemoyeni ukuze yenzeumaleko wokwenziwayechromium oxide kumphezulu. Lo maleko ongabonakaliyo, onokuzilungisa ukhusela isinyithi esingaphantsi kwi-oxidation kunye ne-corrosion.
Okukhona uphezulu umxholo wechromium, kokukhona uxhathisa ukudleka ngcono. Amabakala amaninzi ensimbi engenasici aquka nezinye izinto ezidibanisayo ezifananickel, molybdenum, kwayeinitrogenukwandisa lo mqobo wokhuselo, ngakumbi kwiindawo ezinobundlobongela.
Iindidi eziqhelekileyo zokuMbosa kunye nokuziphatha kweNsimbi eNgatyiwayo
Kwanentsimbi engatyiwayo ayikhuselekanga ngokupheleleyo kuzo zonke iintlobo zokubola. Ukuqonda iintlobo eziqhelekileyo kunceda ekukhetheni ibakala elifanelekileyo.
1. Ukonakala ngokubanzi
Lo ngumhlwa ofanayo owenzeka kuwo wonke umphezulu xa utyhileke kwimo engqongileyo eneasidi okanye ye-caustic. Amabanga afana ne-304 kunye ne-316 axhathisa olu hlobo kakuhle.
2. I-Pitting Corrosion
Ivela kwindawo ezityebileyo ngekloridi njengamanzi olwandle okanye iindawo zamadama. Molybdenum-eziqulathe amabakala ezifana316 or 904Lzinika ukuxhathisa okuphezulu.
3. I-Crevice Corrosion
Yenzeka kwiindawo ezixineneyo apho ioksijini ingenakufikelela kumphezulu ukugcina umaleko wokwenziwa. Ukukhetha i-low-carbon okanye i-high-alloy grade kunganceda ukuthintela oku.
4. Uxinzelelo lwe-Corrosion Cracking
Le yindibaniselwano yoxinzelelo lomatshini kunye nemekobume eyonakalisayo. I-Duplex stainless steels okanye i-high-nickel alloys zihlala zisetyenziselwa ukuxhathisa le nto.

Izinto Eziphembelela Ukunyangwa kweNsimbi eNgatyiwayo
Izinto ezininzi zangaphandle zinefuthe kwindlela intsimbi engenasici eya kwenza ngayo enkonzweni:
-
Ubushushu: Amaqondo obushushu aphezulu anokukhawulezisa ukubola, ngakumbi kwiindawo ezineasidi okanye ezinekloridi etyebileyo.
-
Ukubonakaliswa kwiikloridi: Iiyoni zekloridi zinoburhalarhume kwaye zinokwaphula umaleko wokwenziwa.
-
I-Acidity kunye ne-Alkalinity: Amanqanaba aphezulu e-pH anokuthi abeke esichengeni nakwiintsimbi ezikumgangatho ophezulu.
-
Umphezulu Gqiba: Ukugqiba okugudileyo (okufana neNombolo ye-4 okanye i-2B) ivame ukuxhathisa i-corrosion engcono kuneendawo ezirhabaxa okanye ezikrweliweyo.
-
Isondlo: Ukucoca rhoqo kuthintela ukungcola ukuphula ifilimu ekhuselayo.
Ukukhethwa ngokufanelekileyo, ukufakela, kunye nokugcinwa kunokwandisa kakhulu ixesha lokuphila kwensimbi engenasici kwiindawo ezinobungozi.
