Ikhoyili yensimbi enama-galvanizedukuvimbela ukugqwala ebusweni beshidi lensimbi nokwandisa impilo yalo yesevisi.Ingaphezulu leshidi lensimbi limbozwe ungqimba lwezinc zensimbi.Lolu hlobo lweshidi/ikhoyili yensimbi lubizwa ngokuthi ishidi/ikhoyili.Ikhoyili yensimbi encane icwiliswa ethangini le-zinc elincibilikisiwe, ukuze ungqimba lwe-zinc lunamathele phezulu.Njengamanje, ikhiqizwa ikakhulukazi inqubo yokufaka uthayela eqhubekayo, okungukuthi, ukucwiliswa okuqhubekayo kweshidi lensimbi eligoqiwe ethangini elinezinki elincibilikisiwe ukwenza ishidi/ikhoyili yensimbi.
Ungabala kanjani isisindo sekhoyili yensimbi?Ifomula yokubala isisindo sekhoyili yeshidi eliqinile:
M(kg/m)=7.85*ububanzi(m)*ubukhulu(mm)*1.03
Isibonelo: ugqinsi 0.4*1200 ububanzi: isisindo(kg/m)=7.85*1.2*0.4*1.03=3.88kg/m
Ikhoyili kathayela kufanele ibukeke kahle, futhi akumele kube khona iziphambeko eziyingozi ekusetshenzisweni komkhiqizo, njengokungabi bikho kwe-plating, izimbobo, imifantu, udoti, ukujiya ngokweqile, ukuklwebheka, ukungcola kwe-chromic acid, ukugqwala okumhlophe, njll. Izindinganiso zakwamanye amazwe azicaci kahle mayelana neziphambeko ezithile zokubukeka.Amanye amaphutha athile kufanele abhalwe kunkontileka lapho uyala.
