Ishiti legalvanized kunye nentsimbi engenasici
Iphepha elifakwe igalvanized kukuphepha ukubola komphezulu weplate yentsimbi eshinyeneyo kunye nokwandisa ubomi bayo benkonzo.
Umphezulu wepleyiti yentsimbi eshinyeneyo uqatywe umaleko we-zinc yentsimbi.
Olu hlobo lwamanzi abandayo aqengqelekayo entsimbi lubizwa ngokuba yi-galvanized sheet.
Iimveliso ezishushu eziqengqelekayo zisetyenziswa ikakhulu kumashishini emveliso, afana nolwakhiwo lobunjineli, ishishini elilula, iitroli, ezolimo, ukufuywa kwezilwanyana nokuloba, kunye neenkonzo zorhwebo.
Phakathi kwabo, imboni yokwakha ifanelekile ukuveliswa kweemveliso zemizi-mveliso ezinganyangekiyo kunye nophahla lwentsimbi enombala kunye nophahla lwezakhiwo zoshishino;
ishishini lesinyithi liyisebenzisela ukuvelisa izixhobo zasekhaya, iitshimini zasekuhlaleni, iimpahla zasekhitshini, njl.
kunye neshishini lokuvelisa iimoto lilungele ukuveliswa kweemoto.
Amacandelo e-Anti-corrosion.
Ezolimo, ukufuywa kwezilwanyana kunye nokuloba zisetyenziselwa ukugcina ukutya kunye nokuthutha,ukutya kwenyama kunye nokuveliswa kwefriji yezilwanyana zaselwandle kunye nokuhanjiswa kwemveliso, njl.iinkonzo zoshishino ikakhulu ezisetyenziselwa ukubonelela ngezinto eziphathekayo, ukugcinwa kunye nokupakishwa kwempahla.
Icwecwe lensimbi engenastainless libhekisa kwintsimbi ekwaziyo ukumelana nezinto ezidla ngokudlakadlaka ezifana nerhasi, umphunga,amanzi kunye nezinto ezidliwayo zemichiza ezonakalisayo ezifana neeasidi, iialkali kunye neetyuwa.
Ikwabizwa ngokuba yintsimbi engatyiwayo kunye nentsimbi enganyangekiyo kwiasidi.
Kwizicelo ezithile, intsimbi imelana nezinto ezidla ngokudla ngokubizwa ngokuba yintsimbi engatyiwa,ngelixa intsimbi enganyangekiyo kwizinto ezinyibilikayo ibizwa ngokuba yintsimbi enganyangekiyo kwiasidi.
Ngokwendlela yayo, iipleyiti zensimbi ezingenasici zihlala zahlulahlulwe zibe yintsimbi ye-austenitic, intsimbi ye-ferritic,intsimbi ye-ferritic, i-ferritic metallographic structure (i-duplex) ipleyiti yensimbi engenasici kunye nokuhlalisa ipleyiti yensimbi engenasici.
Ukongeza, inokohlulwa ibe yipleyiti yensimbi engenasici yechromium, ipleyiti yentsimbi ye-chromium-nickel kunye ne-chromium manganese nitrogen plate yentsimbi.
Isizathu
Ukuxhatshazwa kwe-corrosion ye-galvanized stainless sheet iyancipha ngokunyuka kwekhabhoni.
Ke ngoko, umxholo wekhabhoni uninzi lweeplate zetsimbi ezingenasici ziphantsi, azidluli kwi-1.2%,kunye ne-Wc (i-carbon content) yezinye iintsimbi zingaphantsi kwe-0.03% (umzekelo, i-00Cr12).
Into ephambili ye-aluminium alloy element kwipleyiti yensimbi engenasici yiCr (chromium).
Kuphela xa umxholo wamanzi we-Cr udlula ixabiso elithile, intsimbi inokumelana nokubola.
Ngoko ke, umxholo wamanzi we-Cr (chromium) ngokubanzi wamacwecwe ensimbi engenasici ubuncinane yi-10.5%.
Ipleyiti yensimbi engenasici iqulethe izinto ezifana ne-Ni, Ti, Mn, N, Nb, Mo kunye neSi.
Ishiti lentsimbi egxunyekwe ngesinyithi akulula ukwenza umhlwa, umhlwa, umhlwa, okanye umonakalo.
Phakathi kwezinto ezidityanisiweyo zetsimbi zokusetyenziswa kobunjineli, iipleyiti zentsimbi ezingenasici zikwayenye yezinto ezikrwada ezinamandla acinezelayo.
Njengoko ipleyiti yensimbi engenasici inokumelana nokugqwesa okugqwesileyo.
Inokwenza amalungu esakhiwo agcine ngokusisigxina ukuhambelana koyilo lobunjineli bokwakha.
Ipleyiti yensimbi engenasici inechromium nayo inefuthe elinamandla kunye ne-ductility ephezulu,olulungele ukuveliswa, ukusetyenzwa kunye nokuveliswa kwamacandelo, kunye neemfuno zabayili bezakhiwo kunye nabayili jikelele banokuqwalaselwa.
