Ishidi lensimbi eliphehliwe

Ishidi elinama-galvanized ishidi lensimbi elingaphezulu kwalo limbozwe ungqimba lwe-zinc.I-galvanizing iyindlela engabizi kakhulu futhi ephumelelayo yokuvimbela ukugqwala esetshenziswa emhlabeni cishe ingxenye yokukhiqizwa kwe-zinc emhlabeni.
Isicelo:
Ipuleti lensimbi elakhiwe ukuvimbela ingaphezulu lensimbi ukuthi lingagqwali ukuze linwebe impilo yalo yesevisi, elimbozwe ngongqimba lwezinki lwensimbi ebusweni bepuleti lensimbi, ipuleti lensimbi elinezinki elibizwa ngokuthi i-galvanized plate.
Ukwahlukanisa

Ngokusho kokukhiqiza kanye nezindlela zokucubungula zingahlukaniswa ngezigaba ezilandelayo:
idiphu elishisayo ishidi lensimbi.Ishidi lensimbi licwiliswa kubhavu we-zinc oncibilikisiwe ukuze linamathele ishidi lensimbi elicwecwe nge-zinc phezulu.Njengamanje, ikhiqizwa ikakhulukazi inqubo eqhubekayo yokufaka ama-galvanizing, okungukuthi, ipuleti lensimbi elihlanganisiwe licwiliswa ngokuqhubekayo ethangini lokucwenga lapho i-zinc incibilika khona ukuze kwakhiwe ishidi lensimbi;
ishidi lensimbi ehlanganisiwe.Leli shidi lensimbi liphinde likhiqizwe idiphu elishisayo, kodwa ngokushesha ngemva kokuba selikhishiwe, liyashiswa libe cishe ku-500 ° C ukuze lenze ifilimu ye-alloy ye-zinc nensimbi.Leli shidi lika-galvanized linokunamathela okuhle kanye nokushisela kwe-coating;
electro-galvanized steel plate.Ukukhiqizwa kweshidi elinjalo lensimbi eliphehliwe nge-electroplating kunokusebenza okuhle.Kodwa-ke, ukugqoka kuncane futhi ukumelana nokugqwala akukuhle njengalokho kweshidi lokucwilisa elishisayo;
ucwecwe olunohlangothi olulodwa kanye nensimbi enamaceledi ehlukene kabili.Insimbi eyisithako sohlangothi olulodwa, okuwukuthi, umkhiqizo ophenyelelwe ohlangothini olulodwa kuphela.Ikwazi ukuzivumelanisa nezimo kangcono kuneshidi elinamaceleni amabili elinothayela ekushiseleni, ekupendeni, ekwelashweni okulwa nokugqwala kanye nokucutshungulwa.
Ukuze unqobe ukushiyeka kwe-zinc engagcotshiwe ngakolunye uhlangothi, kuneshidi likathayela elimbozwe ungqimba omncane we-zinc ngakolunye uhlangothi, okungukuthi, ishidi elihlukanisa kabili elihlukile;
ingxubevange, ishidi lensimbi eliyinhlanganisela.Yenziwe nge-zinc nezinye izinsimbi ezifana ne-aluminium, i-lead, i-zinc, njll., noma insimbi ehlanganisiwe eyinhlanganisela.Le nsimbi yensimbi inokumelana nokugqwala okuhle kakhulu kanye nezakhiwo ezinhle zokumboza;
Ngaphezu kwalezi zinhlobo ezinhlanu ezingenhla, kukhona namashidi ensimbi anombala, amashidi ensimbi aphrintiwe, namashidi ensimbi enziwe nge-polyvinyl chloride elaminethiwe.Nokho, asetshenziswa kakhulu kusengamashidi ediphu ashisayo.
Izindinganiso zomkhiqizo ezifanele zicacisa ukujiya okujwayelekile, ubude nobubanzi obunconyelwe amashidi anothayela kanye nokubekezelelwa kwawo.Ngokuvamile, uma ishidi elinothayela lishubile, ukubekezelelana kukhudlwana, esikhundleni se-0.02-0.04 mm engaguquki, ukuchezuka kogqinsi nakho kunezidingo ezihlukile ngokuya ngesivuno, i-coefficient eqinile, njll. Ubude nobubanzi bephambuka ngokuvamile 5 mm, ubukhulu beshidi.Ngokuvamile phakathi kuka-0.4-3.2.
Ubuso
(1) Isimo esingaphezulu: Ishidi elinothayela linezimo ezihlukile zokwelashwa kwendawo ngenxa yezindlela zokwelashwa ezihlukene enqubweni yokumboza, njengembali evamile ye-zinc, imbali ecolekileyo ye-zinc, imbali ye-zinc eyisicaba, imbali engena-zinc kanye ne-phosphating surface.Izindinganiso zaseJalimane nazo zicacisa amazinga angaphezulu.
(2) Ishidi likathayela kufanele libe nokubukeka okuhle futhi akumele libe nezinto ezilimazayo ezifana nokungacwebeki, izimbobo, imifantu kanye ne-scum, ukushuba okweqile, imihuzuko, amabala e-chromic acid, ukugqwala okumhlophe, njll. Izindinganiso zakwamanye amazwe azicacile kahle. mayelana neziphambeko ezithile zokubukeka.Amanye amaphutha athile kufanele afakwe ohlwini lwenkontileka lapho uyala.
