Iyini indlela ejwayelekile yokusebenzisa izinto zasekhaya zebanga lensimbi engagqwali engu-430?
Izinhlelo zokusebenza zifaka phakathi iphaneli yangaphakathi yomshini wokuwasha izitsha, isigubhu sangaphakathi somshini wokuwasha, udonga lwangaphakathi lwe-oven ye-microwave, iphaneli yangaphakathi yesiqandisi, isihlungi se-range hood, ibhodi lokudonsa amanzi esinkini sasekhishini, isibambo somnyango wesiqandisi, iphaneli yangaphakathi yomnyango wokuwasha izitsha, kanye nephaneli yangaphandle ye-oven.
Iyini intengo yokuhlinzeka ngokuqina kwebanga lensimbi engagqwali engu-430 uma kuqhathaniswa namazinga angu-304 no-316?
Ibanga le-430 lizinzile kakhulu ngenxa yokuqukethwe okuphansi kwe-nickel kanye nokwakheka kwe-chromium kuphela. Ibanga le-430 lisekela izindleko eziphansi ngo-15% kuya ku-25% nge-kg uma kuqhathaniswa nebanga le-304 kanye nezindleko eziphansi ngo-25% kuya ku-35% nge-kg uma kuqhathaniswa nebanga le-316.
Iyini ububanzi obujwayelekile bokujiya kwebanga lensimbi engagqwali engu-430 ekusetshenzisweni kwemishini yasekhaya?
Igeyiji encane (0.3 kuya ku-0.5 mm) ingeyephaneli yangaphakathi yomshini wokuwasha izitsha kanye nesihlungi se-range hood. Igeyiji ephakathi (0.5 kuya ku-1.0 mm) ingeyesigubhu sangaphakathi somshini wokuwasha. Igeyiji ejwayelekile (1.0 kuya ku-2.0 mm) ingeyesinki yasekhishini kanye nephaneli yangaphandle ye-oven.
Iyini indlela ejwayelekile yokuqeda ubuso be-stainless steel engu-430 ohlelweni lokusebenza lwemishini yasekhaya?
I-2B ingeyephaneli yangaphakathi. I-BA ingeyephaneli yangaphandle. I-No.4 ingeyesinki yasekhishini kanye nesibambo somnyango. I-No.8 ingeyengaphandle kwemishini yasekhaya esezingeni eliphezulu.
Iyini intengo ye-nickel ye-LME yebanga le-430 uma kuqhathaniswa namabanga angu-304 kanye no-316L?
Ibanga le-430 linokuvezwa kwentengo ye-nickel ye-0% ye-LME. Ibanga le-304 linokuvezwa kwentengo ye-nickel ye-8% ye-LME. Ibanga le-316L linokuvezwa kwentengo ye-nickel ye-10% ye-LME. Ibanga le-430 lisekela ukubikezelwa kwezindleko ezibikezelwayo emjikelezweni wokukhiqiza wezinyanga eziyi-12.
Iyini i-TCO encishisiwe ejwayelekile kusukela ebangeni lika-430 uma kuqhathaniswa nebanga lika-304 lohlelo lokusebenza lwemishini yasekhaya?
Ibanga le-430 livame ukusekela i-TCO ephelele ephansi ngo-18% kuya ku-25% emjikelezweni wokukhiqiza wezinyanga eziyi-12 ngezindleko zeyunithi ngayinye ephansi kanye nezindleko eziphansi ze-scrap uma kuqhathaniswa nebanga le-304.
