Umenzi weBolt eGlastiki ekumgangatho ophezulu
Izixhobo ezisisiseko kunye neMigangatho
Izinto Eziqhelekileyo: Izinto ezisisiseko ikakhulu yintsimbi. Intsimbi enekhabhoni ephantsi (njenge-Q235) ifanelekile kwiibholiti eziqhelekileyo zebanga eli-4.8, ngelixa intsimbi enekhabhoni ephakathi (njenge-35# kunye ne-45# intsimbi) isetyenziselwa iibholiti ezinamandla aphezulu. Kwizicelo ezikhethekileyo, kusetyenziswa intsimbi engagqwaliyo eshushu ediphiweyo, efanelekileyo kwiindawo ezinobungozi kakhulu ezifana neendawo zeekhemikhali kunye nolwandle. Nangona ubhedu lunokusetyenziselwa iibholiti ze-galvanized, ixabiso lalo eliphezulu lithintela ukusetyenziswa kwalo kunxibelelwano lombane.
Imigangatho: Umzekelo, iibholthi ze-hexagonal ezishushu ezidiphiweyo ze-8.8 grade zihambelana nemigangatho yesizwe ye-GB/T5782 (enemisonto embalwa) kunye ne-GB/T5783 (enemisonto epheleleyo). Iinkcukacha zemisonto zigubungela i-M1.6 - M20 nangaphezulu, kunye neenkcukacha ezicacileyo zemigangatho efana nepitch kunye nobude beebholthi ezahlukeneyo.
Izinto Ezibalulekileyo Eziqwalaselweyo: Ubushushu obuphezulu bokugalela i-hot-dip bunokuchaphazela kancinci iimpawu zoomatshini beebholiti ezinamandla aphezulu zebanga lesi-8.8 nangaphezulu, nto leyo efuna ulawulo olungqongqo lweeparameter zenkqubo ngexesha lokuveliswa. Ugalela i-cold galvanizing, kwelinye icala, isebenzisa inkqubo yobushushu obuphantsi engatshintshiyo iimpawu zezinto ezisisiseko, nto leyo eyenza ukuba ifaneleke ngakumbi kwiibholiti ezichanekileyo okanye izinto ezichanekileyo ezifuna amandla aphezulu. Ngaphezu koko, zombini ezi nkqubo zifuna amanyathelo okukhusela okusingqongileyo: ugalela i-hot-dip galvanizing kufuneka kulawulwe ukukhutshwa kwe-zinc fume, ngelixa ugalela i-cold galvanizing ufuna unyango olufanelekileyo lwamanzi amdaka asebenzisa i-electroplating.
