Ishidi elakhiwe ngamapulangwe kanye neshidi lensimbi engagqwali
Ishidi elinothayela elokugwema ukugqwala kobuso bepuleti lensimbi eliwugqinsi futhi likhulise impilo yalo yesevisi.
Ingaphezulu lepuleti lensimbi eliwugqinsi limbozwe ungqimba lwezinc eyinsimbi.
Lolu hlobo lweshidi lensimbi eligoqiwe elibandayo libizwa ngokuthi yi-galvanized sheet.
Imikhiqizo efakwe uthayela oshisayo isetshenziswa kakhulu ezimbonini zokukhiqiza, njengokwakha ubunjiniyela, imboni yezibani, amatroli, ezolimo, ukufuywa kwezilwane nezokudoba, kanye nezinsizakalo zentengiso.
Phakathi kwazo, imboni yezokwakha ifaneleka ukukhiqizwa kwemikhiqizo yezimboni engagqwali kanye nophahla lwensimbi olunemibala kanye nama-grills ophahleni lwezakhiwo zezimboni;
imboni yensimbi iyisebenzisela ukukhiqiza izinto zasendlini, oshimula bomphakathi, izimpahla zasekhishini, njll.,
futhi imboni yokukhiqiza izimoto ilungele ukukhiqizwa kwezimoto.
Izingxenye ze-anti-corrosion.
Ezolimo, ukufuywa kwezilwane kanye nezokudoba ikakhulukazi zisetshenziselwa ukugcina ukudla nokuthutha,ukudla kwenyama kanye nokukhiqizwa kwesiqandisi sezilwane zasolwandle kanye nezinto zokucubungula, njll.izinsiza zebhizinisi ikakhulukazi ezisetshenziselwa ukuhlinzeka ngezinto ezibonakalayo, ukugcinwa kanye nempahla yokupakisha.
Ishidi lensimbi engagqwali lisho insimbi ekwazi ukumelana nezinto ezigqwala ezibuthakathaka njengegesi, isitimu,amanzi kanye namakhemikhali emvelo agqwalayo njengama-asidi, ama-alkali nosawoti.
Eyaziwa nangokuthi insimbi engagqwali nensimbi engamelana ne-asidi.
Kwezinye izinhlelo zokusebenza, insimbi imelana nezinto ezibolayo ezivame ukubizwa ngokuthi insimbi engagqwali,kuyilapho insimbi imelana nezinto ezincibilikayo ibizwa ngokuthi insimbi engamelana ne-asidi.
Ngokomshini wayo, amapuleti ensimbi engagqwali ngokuvamile ahlukana abe yinsimbi ye-austenitic, insimbi ye-ferritic,insimbi ye-ferritic, i-ferritic metallographic structure (i-duplex) ipuleti lensimbi engagqwali kanye nendawo yokuhlala eqinile yensimbi engagqwali.
Ngaphezu kwalokho, ingahlukana ibe ipuleti lensimbi engagqwali ye-chromium, ipuleti lensimbi ye-chromium-nickel ne-chromium manganese nitrogen steel stainless steel plate.
Isizathu
Ukumelana nokugqwala kweshidi lensimbi engenazinsimbi kuncipha ngokwanda kokuqukethwe kwekhabhoni.
Ngakho-ke, okuqukethwe kwekhabhoni kwamapuleti amaningi ensimbi engagqwali kuphansi, akudluli ku-1.2%,kanye ne-Wc (okuqukethwe kwekhabhoni) kwezinye izinsimbi ngisho nangaphansi kuka-0.03% (ngokwesibonelo, 00Cr12).
Isici esiyinhloko se-aluminium alloy epuleti lensimbi engagqwali yi-Cr (chromium).
Kuphela uma okuqukethwe kwamanzi kwe-Cr kudlula inani elithile, insimbi inokumelana nokugqwala.
Ngakho-ke, okuqukethwe kwamanzi okujwayelekile kwe-Cr (chromium) amapuleti ensimbi engagqwali okungenani ku-10.5%.
Ipuleti lensimbi engagqwali liqukethe nezinto ezifana ne-Ni, Ti, Mn, N, Nb, Mo kanye ne-Si.
Ishidi lensimbi engagqwali elakhiwe akulula ukubangela ukugqwala, ukugqwala, ukugqwala, noma ukulimala.
Phakathi kwezinto ezihlanganisiwe zensimbi zokusetshenziswa kobunjiniyela, amapuleti ensimbi engenasici nawo angenye yezinto ezingavuthiwe ezinamandla amakhulu okucindezela.
Njengoba ipuleti lensimbi engenasici linokumelana nokugqwala okuhle kakhulu.
Ingenza amalungu esakhiwo alondoloze unomphela ukuvumelana komklamo wobunjiniyela bezakhiwo.
Ipuleti lensimbi engagqwali eline-chromium nalo linomthelela oqinile kanye ne-ductility ephezulu,okuyinto elula ukukhiqizwa, ukucubungula kanye nokukhiqiza izingxenye, kanye nezidingo abaklami bezakhiwo kanye abaklami jikelele zingabhekwa.
