Umkhiqizi we-Galvanish Bolt Wekhwalithi Ephezulu
Izinto Eziyisisekelo Nezindinganiso
Izinto Ezivamile: Izinto eziyisisekelo ikakhulukazi ziyinsimbi. Insimbi enekhabhoni ephansi (njenge-Q235) ifanelekela amabhawodi ajwayelekile ebanga elingu-4.8, kuyilapho insimbi enekhabhoni ephakathi (njengensimbi engu-35# kanye ne-45#) isetshenziselwa amabhawodi anamandla aphezulu. Ngezicelo ezikhethekile, kusetshenziswa insimbi engagqwali egayiwe eshisayo, efanelekile ezindaweni ezigqwala kakhulu njengezindawo zamakhemikhali nezasolwandle. Ngenkathi ithusi lingasetshenziswa futhi kumabhawodi agayiwe, izindleko zalo eziphakeme zikhawulela ukusetshenziswa kwalo ekuxhumeni kukagesi.
Izindinganiso: Isibonelo, amabholthi ayisithupha aqinile afakwe i-hot-dip angu-8.8 ahambisana nezindinganiso zikazwelonke ze-GB/T5782 (ezinemicu engaphansi) kanye ne-GB/T5783 (ezinemicu egcwele). Imininingwane yentambo ihlanganisa i-M1.6 - M20 nangaphezulu, enemininingwane ejwayelekile ecacile yamapharamitha afana nephimbo nobude bosayizi abahlukene bebholthi.
Okubalulekile: Izinga lokushisa eliphezulu le-hot-dip galvanizing lingathinta kancane izakhiwo zemishini zama-bolts anamandla aphezulu ebanga lesi-8.8 nangaphezulu, okudinga ukulawulwa okuqinile kwemingcele yenqubo ngesikhathi sokukhiqiza. I-cold galvanizing, ngakolunye uhlangothi, isebenzisa inqubo yokushisa ephansi engashintshi izakhiwo zezinto eziyisisekelo, okwenza ifaneleke kakhulu kuma-bolts anembile noma izingxenye ezinembile ezidinga amandla aphezulu. Ngaphezu kwalokho, zombili lezi zinqubo zidinga izinyathelo zokuvikela imvelo: i-hot-dip galvanizing idinga ukulawula ukukhishwa kwe-zinc fume, kuyilapho i-cold galvanizing idinga ukwelashwa okufanele kwamanzi amdaka asebenzisa i-electroplating.
