Luluphi unyango olungaphezulu lokufakwa kwentambo?

Umtya wokufaka unyango lomphezulu ubhekisa kwinkqubo yokwenza umaleko wokugquma kumphezulu wesixhobo sokusebenza ngendlela ethile.. Emva konyango olungaphezulu, ukufaka imisonto kunokubonisa inkangeleko entle ngakumbi, kunye nokumelana nokubola kokufakwa kwentambo ngokwayo kuya kuphuculwa. Eyona njongo ibaluleke ngakumbi kukwenza umsonto uzifake ngokwawo ukuchasana nomhlwa, ukuze kwandiswe ukuthembeka kunye nokuziqhelanisa ne-fastener. Electroplating, eshushu-dip galvanizing, kunye nokucwenga ngoomatshini zezona ndlela zintathu ziqhele ukusetyenziswa kunyango lomphezulu wokufakwa kwentambo.

1. Electroplating
I-electroplating yofakelo lwentambo ibhekisa ekuntywiliseleni iindawo zofakelo lwentambo ekufuneka zityatyekwe kwisisombululo esithile esimanzi.. Isisombululo samanzi siya kuqulatha ezinye iikhompawundi zetsimbi ezigciniweyo. Ngele ndlela, emva kokuba yangoku idlula kwisisombululo samanzi, izinto zetsimbi kwisisombululo zigqithise kwaye zibambelele ekufakeni intambo. kwinxalenye entywilisiweyo ye-firmware. I-electroplating ye-fasteners ngokubanzi ibandakanya i-zinc plating, ubhedu, nickel, ichromium, ingxubevange yobhedu-nickel, njl. Ngamanye amaxesha ubilise umnyama (luhlaza), iphosphating, njl. nazo zibandakanyiwe.

2. Idiphu eshushu igalela
I-Hot-dip galvanizing of fasteners kukuntywilisela imisonto yentsimbi yekhabhoni efakwe kwisitya esinyibilikisiweyo sezinc esinobushushu obumalunga ne-510°C., ukuze i-iron-zinc alloy kumphezulu we-fastener iguqulwe ibe yi-zinc passivated.. Ukufumana umphumo wonyango ongaphezulu (iyafana ne-aluminiyam yediphu eshushu)

3. Ukucwenga koomatshini
Ukufakwa komsonto ngoomatshini kubhekiselele ekusebenziseni iindlela ezithile zomzimba kunye neekhemikhali ukuchaphazela umphezulu wofakelo lwentambo ngomgubo wentsimbi ogqunywe., ukuze isinyithi esigqunyiweyo senza i-coating kumphezulu we-fastener ngokusebenzisa i-welding ebandayo ukufezekisa umphumo wonyango we-Surface. I-Mechanical Plating ye-fasteners ifaneleka kakhulu kwiindawo ezisecaleni ezifana nezikrufu, amandongomane kunye newashers.

Ukugweba umgangatho womsonto faka unyango lomphezulu, ikakhulu kukukhangela ukuba amandla okuchasana nokubola kofakelo lwentambo anyuswe ngokufanelekileyo kwaye ukonyuka kuyahlangabezana neemfuno ezilindelekileyo.. Indlela yokuhlola kukulinganisa indawo yokusebenza yemveliso, misela iimeko zovavanyo, kwaye wenze iimvavanyo zokubola kuyo. Isinyathelo sesibini kukujonga inkangeleko.
