Ngaba ngokwenene intsimbi engatyiwa yintsimbi?
Intsimbi estainless (Stainless Steel) iyamelana nomoya, umphunga, amanzi kunye nezinye iindaba ezibuthathaka ezidliwayo okanye intsimbi engenasici. Ukuxhatshazwa kwayo kwe-corrosion kuxhomekeke kwizinto ze-alloy eziqulethwe kwintsimbi. Ngokubanzi, umxholo wechromium mkhulu kune-12% kwaye ine-Corrosive steel ibizwa ngokuba yintsimbi engatyiwa. I-Chromium yinto esisiseko yokufumana ukuxhathisa ukubola kwentsimbi engatyiwayo. Xa umxholo wechromium kwintsimbi ufikelela malunga ne-12%, i-chromium idibana neoksijini kwindawo engcolisayo ukuze yenze ifilimu ebhityileyo ye-oxide (ifilimu yokudlula) kumphezulu wentsimbi. ) Ukuthintela ukubola okuqhubekayo kwe-substrate yensimbi. Xa ifilimu ye-oxide yonakaliswa ngokuqhubekayo, ii-athomu ze-oksijini emoyeni okanye ulwelo ziya kuqhubeka zingena okanye ii-athomu zetsimbi kwintsimbi ziya kuqhubeka zihlukana, zenze i-oxyde yensimbi ekhululekile, kwaye i-stainless steel surface iya kugqwala ngokuqhubekayo.
Ubungakanani bentsimbi engatyiwayo yokuchasana nokubola butshintsha kunye nokwakheka kweekhemikhali zentsimbi ngokwayo, imeko yokhuseleko, iimeko zokusetyenziswa, kunye nohlobo lokusingqongileyo. Umzekelo, umbhobho wentsimbi oyi-304 unokumelana nokugqwesa okugqwesileyo komhlwa kwindawo eyomileyo necocekileyo, kodwa uya kuba nomhlwa ngokukhawuleza xa usiwa kummandla wonxweme lolwandle kwinkungu yolwandle equlethe isixa esikhulu setyuwa. kulungile. Ngoko ke, akusiyo nayiphi na insimbi engenasici, enokumelana nokubola kunye nokugqwala phantsi kwayo nayiphi na indawo.
