Enye indlela enceda ukugcina unikezelo luzinzile kwaye ngenxa yoko lugcina luneendleko ezifanelekileyo kukuhlaziya kwakhona.

Amaxabiso entsimbi engenastainless anokuguquguquka ngokuhambelana neemeko zemarike yehlabathi njengokwahluka kwamaxabiso kwizinto ezikrwada, amaxabiso ombane, kunye nemfuno yokuvelisa. Ngokomzekelo, ukuhluka kwexabiso le-nickel kunokuchaphazela insimbi engenasici kakhulu, ubukhulu becala iindidi ze-austenitic, ezinomxholo ophezulu we-nickel. Nangona kunjalo, i-nickel ephantsi engabizi kakhulu okanye i-nickel-free efana ne-ferritic stainless steel zezona ndlela zibalaseleyo zokusetyenziswa okungafunekiyo.

Kweziphi iimeko apho iStainless Steel ikhethwayo?

Imizi-mveliso eyahlukeneyo ikuyo ngenxa yokuba inobuxhakaxhaka be-corrosion kunye nokuqina ecaleni kobuhle. Ezi ziindawo ezimbalwa apho intsimbi engenastainless ifumana ukusebenza naphi na apho izinto zisesichengeni sokufuma, imichiza, okanye ezinye iiarhente ezibangela ioxidation: izixhobo zaselwandle, imibhobho, kunye nezityalo zekhemikhali. Kwakhona kufanelekile ukusetyenziswa kwiimeko ezifanelekileyo zococeko ezifana nokulungiswa kokutya, amayeza, kunye nokufakelwa kwezonyango, apho ucoceko lubaluleke kakhulu kwaye kulula ukuvala inzala kuqwalaselwa. Ngaphandle koko, insimbi engenasici ifumana amandla ayo kwaye ilungile ukuyisebenzisa kwiindawo ezinobushushu obuphezulu; uninzi lweeprojekthi zokwakha zifuna inkxaso yesakhiwo kunye nokugquma kunye noyilo loyilo olunenjongo yokudibanisa ukuqina kunye nobuhle. Umzekelo, ukufuna umlinganiselo othile wokukhanya ngaphandle kokuthomalalisa amandla, amabakala entsimbi engenasici afana ne-duplex okanye ezo zantlukwano ze-martensitic zifumana okuphambili. Kwaye ke ezi zakhiwo zenza ukuba ibe yimathiriyeli yokwakha enolwazi kwaye ethembeke kakhulu kushishino, urhwebo kunye nenjongo yokuhlala.
