Izindaba

Ishidi elinothayelaiyinsimbi esetshenziswa kabanzi emikhakheni efana nezakhiwo, ugesi, izimoto, ifenisha, nemishini.
Inezinzuzo ezifana ne-anti-corrosion, ukuqina, ubuhle, nokuphatheka, ngakho-ke ithandwa kakhulu yimboni nabathengi.
Kuzinhlelo zokusebenza ezisebenzayo, ukukhetha ukucaciswa okufanele kweishidi likathayelakubaluleke kakhulu.Lesi sihloko sizokwethula ulwazi olufanele lokucaciswa kweshidi elinothayela kusuka ezicini eziningi ezifana nokokusebenza, usayizi, nokuphathwa kwendawo.

1. Izinto
Ishidi elinothayela ikakhulukazi liqukethe ipuleti lensimbi ne-zinc, elinokuqukethwe kwe-zinc ngokuvamile okusukela ku-120-275g/m ² Between.
Kunezinhlobo ezihlukahlukene zamapuleti ensimbi, okuhlanganisa i-carbon steel evamile, i-alloy low high-strength steel, insimbi engagqwali, njll.
Amapuleti ensimbi ahlukene anokusebenza okuhlukile ezimeni ezihlukene zohlelo, futhi abathengi kufanele bakhethe izinto ezifanele ngokusekelwe ezidingweni zabo zangempela.
2. Ubukhulu
Ubukhulu beshidi likathayela buhlanganisa izici ezintathu: ukujiya, ububanzi, nobude.
Ngokuvamile, ukujiya kungu-0.15-4.0mm, ububanzi buyi-600-1500mm, nobude buyi-0-6000mm.
Ukukhethwa kokuqina nobubanzi kufanele kucatshangelwe ngokucophelela ngokusekelwe ezihlosweni ezithile kanye namandla okuthwala.
Ekusetshenzisweni okungokoqobo, kusetshenziswa ishidi likathayela losayizi ojwayelekile, elingenza kube lula ukucutshungulwa nokusetshenziswa.
3. Ukwelashwa kwendawo
Ukwelashwa okungaphezulu kweshidi elinothayela kunomthelela omkhulu empilweni yayo yesevisi kanye nobuhle.
Njengamanje, izindlela ezijwayelekile zokwelapha indawo emakethe ikakhulukazi zifaka ukugalela izinti okuvamile, ukufutha, i-Hot-dip galvanization, njll.
Phakathi kwazo, i-galvanizing evamile iyindlela evamile yokwelashwa kwendawo, efanelekile ngokujwayelekile ukulwa nokugqwala kanye nezidingo zobuhle.
I-spraying kanye ne-Hot-dip galvanization ifanele izikhathi ezinezidingo eziphezulu zokuvimbela ukugqwala kanye nobuhle, njengemoto, imishini, ugesi kanye nezinye izinkambu.
4. Ukukhetha imininingwane
Ukukhethwa kwezichasiselo ezifanele zeshidi likathayela kudinga ukucatshangelwa okuphelele okusekelwe kuzimo ezithile zokusetshenziswa nezidingo.
Ngokuvamile, izici ezilandelayo zidinga ukuqashelwa:
1. Umthamo wokuthwala: Umthamo wokuthwala kungenye yezinto ezibalulekile okufanele uzicabangele lapho ukhetha ukucaciswa kweshidi likathayela.
Lapho ukhetha ukucaciswa kweshidi lika-galvanized, kuyadingeka ukucabangela ngokugcwele izidingo zangempela kanye namandla okuthwala, bese ukhetha izinto ezifanele namasayizi.
2. Izidingo zokunqanda ukugqwala kanye nobuhle: Ukuvimbela ukugqwala kanye nobuhle ezinye izici ezimbili ezibalulekile okufanele zicatshangelwe lapho kukhethwa imininingwane yeshidi elinothayela.
Ezikhathini ezinezidingo eziphezulu, njengemoto, imishini, ugesi nezinye izinkambu, kutuswa ukuba ukhethe ishidi elinothayela ngokufafaza noma ngokufaka i-Hot-dip galvanization.
3. Izidingo zokucubungula: Izidingo zokucubungula zeshidi likathayela nazo ziyisici okufanele icatshangelwe lapho kukhethwa imininingwane.
Izindlela ezihlukene zokucubungula zinezidingo ezihlukene zamashidi anamathangi, futhi abathengi kufanele bakhethe ukucaciswa okufanele okusekelwe ezidingweni zabo zangempela.
5. Isiphetho
Iukukhethwa kweshidi likathayelaUkucaciswa kunomthelela omkhulu empilweni yayo yesevisi kanye nobuhle.
Lapho ukhetha ukucaciswa, kuyadingeka ukuthi ucabangele ngokuningiliziwe izimo nezidingo ezithile zokusetshenziswa, bese ukhetha izinto ezifanele, osayizi, nezindlela zokwelapha ezingaphezulu.
