Zingaki izinhlobo zamashidi anothayela ezingahlukaniswa ngokwezindlela zokukhiqiza nezindlela zokucubungula?

Amashidi anamagalaniingahlukaniswa ngezigaba ezilandelayo ngokwezindlela zokukhiqiza nezokucubungula:

(1)Ishidi elishisayo elicwilisiwe lensimbi. Ishidi lensimbi elincanyana licwiliswa kubhavu we-zinc oncibilikisiwe ukwenza ishidi lensimbi elincanyana elinongqimba lwezinc olunamathela ebusweni balo. Njengamanje, ukusetshenziswa okuyinhloko okuqhubekayo kokukhiqizwa kwenqubo yokufaka uthayela, okungukuthi, imiqulu yensimbi icwiliswe ngokuqhubekayo okugeza okuncibilikisiwe kwe-zinc eyenziwe ngensimbi;

(2) insimbi eyingxubevange. Le nsimbi yensimbi nayo yenziwa ngokucwiliswa okushisayo, kodwa ngokushesha ngemva kokushiya ithangi, ifudunyezwa ibe ngu-500 ℃, ukuze ikhiqize ifilimu elincanyana le-zinc ne- iron alloy. Lolu hlobo lweshidi lensimbi elinezinsimbi lunokunamathela okuhle kopende kanye nokushisela;

(3) Ishidi lensimbi elakhiwe nge-electro-galvanized. Ukukhiqiza leli shidi lensimbi elinamandla ngendlela ye-electroplating kunokusebenza okuhle. Kodwa-ke, ukugqoka kuncane futhi ukumelana nokugqwala akukuhle njengalokho kweshidi elishisayo lokucwilisa;

(4) Ishidi lensimbi elinothayela elinohlangothi olulodwa nezinhlangothi ezimbili. Ishidi lensimbi eliseceleni elilodwa, okungukuthi, elifakwe ama-galvanized kuphela ohlangothini olulodwa lomkhiqizo. Ikwazi ukuzivumelanisa nezimo kangcono kuneshidi elinamaceleni amabili elithathiwe mayelana nokushisela, ukupenda, ukwelashwa okulwa nokugqwala kanye nokucubungula. Ukuze unqobe ukushiyeka kwe-zinc engamboziwe yohlangothi olulodwa, kunolunye uhlobo lweshidi likathayela elimbozwe ungqimba oluncane lwe-zinc ngakolunye uhlangothi, okungukuthi, ishidi elihlukanisayo elinezinhlangothi ezimbili;

(5) I-alloy neshidi lensimbi eliyinhlanganisela. Yenziwe nge-zinc nezinye izinsimbi ezifana ne-aluminium, i-lead, i-zinc namanye ama-alloys ngisho nensimbi ehlanganisiwe eyinhlanganisela. Lolu hlobo lwepuleti yensimbi lunakho kokubili ukusebenza okuhle kakhulu kokugqwala kanye nokusebenza okuhle komdwebo;

Ngaphezu kwalokhu okuhlanu okungenhla, kukhona nensimbi enombala, insimbi ephrintiwe futhi ependiwe, insimbi eyenziwe nge-PVC elayiniwe, njll. Nokho, evame ukusetshenziswa kakhulu okwamanje namanje.I-Hot Dip Ipuleti Elinothayela.

Ukubukeka kwensimbi yama-galvanized
[1] Isimo sobuso:Ipuleti Elivunyiwengenxa yenqubo yokugcoba ekwelapheni izindlela ezahlukene, isimo esingaphezulu sihlukile, njengembali evamile ye-zinc, imbali enhle ye-zinc, imbali ye-zinc flat, ayikho imbali ye-zinc, nokwelashwa kwe-phosphate ebusweni nokunye. Izinga laseJalimane liphinde licacise izinga eliphezulu.
[2] Ishidi elinothayela kufanele libe nokubukeka okuhle, akumele kube namaphutha ayingozi ekusetshenzisweni komkhiqizo, njengokungabi bikho okucwebezelayo, izimbobo, ukuqhekeka, kanye ne-slag, okungaphezu kobukhulu be-plating, ukuhuzuka, amabala e-chromic acid, ukugqwala okumhlophe, nokunye.

Izakhiwo zemishini
[1] Ukuhlolwa kwe-Tensile:
Inkomba yeshidi lensimbi elithambile (iyunithi: g/m2)
I-JISG3302 Ikhodi Z12 Z18 Z22 Z25 Z27 Z35 Z43 Z50 Z60
Inani lamagalanisi 120 180 220 250 270 350 430 500 600
I-ASTMA525 Ikhodi A40 A60 G60 G90 G115 G140 G165 G185 G210
Inani lamagala 122 183 183 275 351 427 503 564 640
① Ngokuvamile, amashidi enziwe ngothayela anesakhiwo, aqinile nadonsa ngokujulile adingekayo ukuze abe nezindawo eziqinile. Ishidi elinothayela lesakhiwo liyadingeka ukuze libe nephuzu lokukhiqiza, amandla aqinile kanye nokwelula, njll.; ukuqina kudinga ukunwetshwa kuphela. Amanani athile abona okuthi “8” kulesi sigaba samazinga omkhiqizo afanelekile;
② indlela yokuhlola: iyafana nendlela yokuhlola insimbi evamile emincane, bona okuthi “8” okunikezwa izindinganiso ezifanele kanye “neshidi lensimbi yensimbi yekhabhoni evamile” esohlwini lwendlela yokuhlola.

[2] Ukuhlolwa kokugoba:
Ukuhlolwa kokugoba kuwumsebenzi oyinhloko wokukala ukusebenza kwenqubo yeshidi lensimbi, kodwa izindinganiso zikazwelonke zezidingo ezihlukahlukene zeshidi lensimbi azihambisani, izinga lase-US, ngaphezu kwebanga lesakhiwo, okunye akudingi ukuhlolwa kokugoba nokuqina. I-Japan, ngaphezu kwebanga lesakhiwo, ishidi likathayela wokwakha kanye neshidi likathayela elivamile ngaphandle kwamanye ayadingeka ukwenza ukuhlolwa kokugoba.

Ukumelana nokugqwala kweshidi elinama-galvanized kunezici ezimbili eziyinhloko:

1, indima ye-coating yokuzivikela
Ebusweni obunothayela ukwenza ifilimu ye-oxide eminyene

2, lapho ngenxa yesizathu esithile imihuzuko ku-zinc enamathela, i-zinc ezungezile isetshenziswa njenge-cation ukuvimbela ukugqwala kwensimbi.
