Imibuzo Ebuzwa Rhoqo (FAQ)

Uthini umahluko phakathi kweebholithi zeBakala 8.8 kunye neBakala 10.9?

Iibholithi zeBanga le-10.9 zineendidi eziphakamileyo zokuzibamba kunye namandla emveliso kuneebholithi zeBanga lesi-8.8. Ngokukodwa, iBanga le-10.9 linamandla asezantsi e-1040 MPa kunye namandla esivuno angama-940 MPa, ngelixa iBakala 8.8 linama-800 e-MPa tensile kunye nama-640 MPa amandla esivuno. IBakala 10.9 lisetyenziselwa izicelo ezibaluleke ngakumbi, ezinomthwalo ophezulu.

Ngaba iibholiti zamandla aphezulu zingaphinda zisetyenziswe?

Ngokubanzi, iibholiti zesakhiwo zamandla aphezulu (ezifana ne-ASTM A325/A490 okanye i-ISO 10.9) azikhuthazwa ukuba ziphinde zisetyenziswe emva kokuba ziqinisiwe ekulayisheni kwangaphambili. Ukolula kunye nokuguqulwa kwentambo kunokuphazamisa ingqibelelo yabo. Kwizicelo ezingabalulekanga, ukuba ibholiti ayibonisi zimpawu zokolula okanye umonakalo womsonto, ingaphinda isetyenziswe ngononophelo, kodwa ukutshintshwa kolona qheliselo lolona lulo lolona qheliselo lokhuseleko olubalulekileyo.

Ndiyinqanda njani i-galvanic corrosion ngeebholiti ezomelele kakhulu?

I-galvanic corrosion yenzeke xa iintsimbi ezingafaniyo zidibana phambi kwe-electrolyte. Ukuthintela oku, sebenzisa iibholiti ezenziwe ngezinto ezikufutshane nesiseko sesinyithi kwi-galvanic series, okanye sebenzisa i-insulating washers kunye nemikhono. Iingubo ezifana neDacromet okanye i-hot-dip galvanizing nazo zibonelela ngomqobo. Gwema ukusebenzisa iibholiti ze-aluminium ezinezakhiwo zetsimbi ngaphandle kokuzihlukanisa ngokufanelekileyo.

Buthini ubomi beshelufu yeebholiti zamandla aphezulu?

Iibholiti zamandla aphezulu azinawo umhla omiselweyo wokuphelelwa, kodwa ziyakwazi ukubola kunye ne-hydrogen embrittlement ekuhambeni kwexesha ukuba zigcinwe ngokungafanelekanga. Zigcine kwindawo eyomileyo nengaphakathi endlini kude neekhemikhali. Ukuba iibholiti zigcinwe ngaphezulu kweenyanga ezi-6, ngakumbi ukuba zigqunyiwe, zihlole ukuba zinomhlwa okanye ukuthotywa komgangatho phambi kokusetyenziswa. Ukuvavanywa kwakhona kungafuneka kwizicelo ezibalulekileyo.

Ngaba ubonelela ngeebholiti zamandla aphezulu e-OEM?
