Uthini umahluko phakathi kwentsimbi yekhabhoni kunye nentsimbi engatyiwayo?

Intsimbi yekhabhoni, ekwabizwa ngokuba yi-carbon steel, ibhekisela kwisinyithi kunye ne-carbon alloys equkethe ngaphantsi kwe-2% ye-carbon, i-carbon steel ngaphezu kwekhabhoni ngokubanzi iqulethe i-silicon, i-manganese, isulfure kunye ne-phosphorus.

Yenziwe ngentsimbi eshayinayo, ekwaziwa ngokuba yintsimbi enganyangekiyo kwiasidi, ibhekisa ekuxhathiseni komoya, umphunga, amanzi kunye nezinye izinto ezibuthathaka ezonakalisayo kunye neeasidi, iialkali, iityuwa kunye nezinye iikhemikhali ezifaka intsimbi yentsimbi. Enyanisweni, intsimbi exhathisayo kwimithombo yeendaba ebuthathaka idla ngokubizwa ngokuba yintsimbi engenasici, kwaye intsimbi exhathisayo kwi-corrosion ye-chemical media ibizwa ngokuba yi-acid-resistant steel.

(1) Ukuxhatshazwa kwe-Corrosion kunye ne-abrasion
Intsimbi engatyiwayo yingxubevange ekwaziyo ukumelana nokudleka ngenxa yemithombo yeendaba edlakadlaka njengomoya, umphunga, amanzi kunye nemithombo yeendaba eziyingozi ngokwemichiza enjengeeasidi, iialkali kunye neetyuwa. Kwaye lo msebenzi unxulunyaniswa ikakhulu nokongezwa kwento engenasici - ichromium. Xa umxholo we-chromium ungaphezu kwe-12%, umphezulu wensimbi engenasici uya kwenza umaleko wefilimu ene-oxidized, eyaziwa ngokuba yifilimu ye-passivation, kunye nolu luhlu lwefilimu ene-oxidized ayiyi kuba lula ukuyichitha kumajelo athile, idlala indima efanelekileyo yokuzahlula, inokumelana nokugqwala okuqinileyo.

I-Carbon steel ibhekisela kwi-iron-carbon alloy equkethe ngaphantsi kwe-2.11% yekhabhoni, eyaziwa ngokuba yi-carbon steel, ukuqina kwayo kuphezulu kakhulu kunensimbi engenasici, kodwa ubunzima bukhulu, iplastiki iphantsi, kulula ukugqwala.

 

(2) iingoma ezahlukeneyo
Intsimbi estainless imfutshane kwintsimbi engenastainless acid-resistant, ukumelana nomoya, umphunga, amanzi kunye nezinye izinto ezibuthathaka ezidliwayo okanye ngentsimbi engatyiwayo ibizwa ngokuba yintsimbi engatyiwa; kwaye iya kuxhathisa kwimithombo yeendaba ezonakalisayo (i-acids, i-alkalis, iityuwa kunye nezinye i-chemical impregnation) i-corrosion yentsimbi ibizwa ngokuba yintsimbi e-acid-resistant.

Intsimbi yeCarbon yintsimbi ye-iron-carbon alloy kunye nomxholo wekhabhoni we-0.0218% ukuya kwi-2.11%. Kwakhona kuthiwa yi-carbon steel. Kananjalo iqulethe ngokubanzi ixabiso elincinci le-silicon, i-manganese, isulfure, kunye ne-phosphorus.

 

(3) Iindleko
Olunye uqwalaselo olubalulekileyo ngumahluko weendleko phakathi kwentsimbi ye-carbon kunye nensimbi engenasici. Nangona iintsimbi ezahlukeneyo zineendleko ezahlukeneyo, intsimbi engatyiwa ngokuqhelekileyo ibiza kakhulu kunentsimbi yekhabhoni, ubukhulu becala ngenxa yokongezwa kwezinto ezahlukahlukeneyo ezixutywayo, ezifana nechromium, nickel, kunye nemanganese, kwintsimbi engenasici.

Xa kuthelekiswa ne-carbon steel, insimbi engenasici inenani elikhulu lezinye i-alloys ezixutywe kwaye zibiza kakhulu xa kuthelekiswa ne-carbon steel. Kwelinye icala, intsimbi yekhabhoni ikakhulu iqulathe izinto ezingabizi kakhulu zentsimbi kunye nekhabhoni. Ukuba unohlahlo lwabiwo-mali oluqinileyo lweprojekthi yakho, i-carbon steel inokuba yeyona ndlela ilungileyo.

 
Yeyiphi enzima, yintsimbi okanye intsimbi yekhabhoni?

I-Carbon steel inzima ngokubanzi kuba iqulethe i-carbon eninzi, nangona i-downside kukuba ithande ukurusa.

Ngokuqinisekileyo ubunzima obuchanekileyo buya kuxhomekeka kwibakala, kwaye kufuneka uqaphele ukuba ayisiyiyo iphakamileyo ubulukhuni obungcono, njengento enzima ithetha ukuba kulula ukuphula, kanti ubulukhuni obuphantsi bunamandla kwaye buncinci ukuba baphule.
