Ukwahlukaniswa Kwamashidi Ayisithako

Ngokusho kokukhiqiza kanye nezindlela zokucubungula zingahlukaniswa ngezigaba ezilandelayo:

a) Ishidi elishisayo lediphu 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;

b) Ishidi elihlanganisiwe lensimbi.Leli shidi lensimbi liphinde likhiqizwe idiphu elishisayo, kodwa ngokushesha ngemva kokuba selikhishiwe, liyashiswa libe cishe ku-500 ° C ukuze lenze ingxubevange ye-zinc nensimbi.Leli shidi lika-galvanized linokunamathela okuhle kanye nokushisela kwe-coating;

c) Ishidi lensimbi.Ukukhiqizwa kweshidi elinjalo lensimbi eliphehliwe nge-electroplating kunokusebenza okuhle.Kodwa-ke, ukugqoka kuncane futhi ukumelana nokugqwala akukuhle njengalokho kweshidi lokucwilisa elishisayo;

d) Insimbi enothayela enohlangothi olulodwa nezinhlangothi ezimbili.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;

e) Ingxubevange, ishidi lensimbi eliyinhlanganisela.Yenziwe nge-zinc nezinye izinsimbi ezifana nomthofu, i-zinc alloy 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.

Amashidi ensimbi angaphinda ahlukaniswe abe amashidi ensimbi ukuze asetshenziswe ngokujwayelekile, ukufulela, amaphaneli angaphandle ezakhiwo, izakhiwo, ama-tiles slabs, ukudweba okuqinile nokujulile.
