I-Dacromet Hex Bolts iKhokela i-Anti-Corrosion Fastening elandelayo 

Ngokungafaniyo ne-zinc ye-electroplated yendabuko, inkqubo ye-Dacromet yazisa akukho hydrogen kwi-substrate. Oku kuphelisa umngcipheko we-hydrogen embrittlement-inzuzo ebalulekileyo xa ugubungela i-hex bolts ephezulu yamabanga 8.8, 10.9, kunye ne-12.9. Isiphumo kukuba a ibholiti ye-hex-proof-proof egcina ingqibelelo epheleleyo yoomatshini ngelixa inikezela ukuxhathisa ukubola kuphezulu kakhulu kuneziphetho eziqhelekileyo.

Kutheni iiBolts zeHex zixhamla kakhulu kwiDacromet

Iibholiti zeHex-ingakumbi iibholiti ze-hex ezinzima-zicaciswe ngokubanzi kwiibhulorho, iinqaba zamandla omoya, oomatshini abanzima, kunye nechassis yeemoto. Ezi zicelo zifuna iziqhoboshi ezidibanisa ukuziphatha okuchanekileyo kwe-torque-tension kunye namashumi eminyaka ubude anti-umhlwa ubomi. I-Dacromet ihlangabezana neemfuno zombini:

• Ukhuseleko olufanayokwijometri yentambo entsonkothileyo ngaphandle kokwakhiwa okuhambelana ne-galvanizing eshushu-dip, ukugcina ukuchaneka komgangatho kunye nokulingana komsonto.
• I-coefficient elawulwayo yokukhuhlana(ngokuqhelekileyo μ = 0.12–0.18 enetopcoat), eyenza umthwalo obambekayo ongaguqukiyo kunye nokusebenza kokuqinisa okuninzi.
• Akukho mngcipheko we-hydrogen embrittlement, okwenza iDacromet ibe yeyona ithandwayo anti-rustukugqiba kwiibholiti ze-hex eziphakamileyo ezisetyenziswa kumalungu abalulekileyo okhuseleko.
• Ukumelana nobushushu ukuya kuma-300°C, igqithise kakhulu imida esebenzayo ye-zinc electroplated.

Ukusebenza kokuTyakala: I-Dacromet vs. Iingubo zeMveli

Uvavanyo lwaselabhorethri oluzimeleyo luhlala lubonisa oko Iibholiti zehex ezigqunywe ngeDacromet zigqithise zombini i-electroplated zinc kunye ne-hot-dip galvanized fasteners kwi-neutral salt-spray (ASTM B117 / ISO 9227) kunye neemvavanyo ze-cyclic corrosion. Olu thelekiso lulandelayo lushwankathela iziphumo eziqhelekileyo kwiinkqubo zokwaleka ezifanayo:

Itheyibhile 1. Ukusebenza okuthelekisayo kweengubo ezinkulu ezichasene ne-corrosion kwi-hex bolts (amaxabiso aqhelekileyo ebhubhoratri).

Kolunye uphononongo olucatshulwe ngokubanzi lwesiqinisekiso se-ASTM A490 iibholithi zolwakhiwo oluqinileyo, iindawo ezigqunywe yiDacromet zibonisiwe. zero umhlwa obomvu emva kweeyure ezili-1,000 zokuvezwa ngokuqhubekayo kwesitshizi setyuwa, ngelixa iibholiti ezenziwe ngoomatshini zibonise ngaphezu kwama-85% umhlwa obomvu kwindawo ebalulekileyo. Nasemva kweeyure ezingama-5,000, iisampulu zeDacromet zibonise kuphela malunga ne-6% umhlwa obomvu-ugqithise ngokumangalisayo i-hot-dip galvanized counterparts ezifikelele kwi-corrosion epheleleyo yomhlaba.

ISayensi eNgemva koKhuseleko oluPhezulu lokulwa nomhlwa

Ekhethekileyo anti-umhlwa ukusebenza kweDacromet kuvela kwiindlela ezintathu ezongezelelweyo:

1. Ukukhuselwa komqobo-Izinc ezinqamlezileyo kunye neeflakes ze-aluminium zenza ikhuselo elixineneyo, elinemigangatho emininzi elithintela ukufuma kunye nokungena kwe-ion ye-chloride.
2. Ukhuseleko lwedini (cathodic).- I-zinc flakes i-corrode ngokukhethekileyo, ikhusela intsimbi ephantsi nokuba i-coating yonakaliswe kwindawo.
3. Ukunyamezela / ukuziphilisa-Iikhompawundi zeChromium-oxide ngaphakathi kwesibophelelo zenza ifilimu ezinzileyo engenzi nto eyenza icothise ngakumbi ukuqhubeka kokubola.

Imbonakalo yeMarike kunye neeMpembelelo zoShishino

Njengoko utyalo-mali lweziseko zophuhliso lwehlabathi lukhawuleza kwaye amaqonga eemoto afudukela kwintsimbi ephezulu, imfuno ethembekileyo. anti-umhlwa kwaye umhlwa-ubungqina izisombululo fastener iyaqhubeka ukunyuka. Abakhi-mkhanya boshishino baqaphela iindlela ezininzi ezomelezayo:

• Ukukhula kwenkcazo– Imigangatho yobunjineli eyongezelelekileyo (kubandakanywa nohlaziyo olunxulumene ne-ASTM F3125 bolts structural bolts) ngoku ibona ngokucacileyo iinkqubo ze-zinc-flake ezifana ne-Dacromet njengezinye iindlela ezamkelekileyo kwi-galvanizing yendabuko yokusetyenziswa kwamandla aphezulu.
• Iingqwalasela zozinzo- Iinkqubo zeDacromet ezisekelwe kumanzi zivelisa inkunkuma enobungozi obungaphantsi kunemizila emininzi ye-electroplating, ukulungelelanisa nokuqiniswa kwemimiselo yokusingqongileyo.
• Ixabiso lilonke lobunini- Nangona iindleko zeyunithi zinokuba phezulu kune-zinc plating esisiseko, ubomi benkonzo eyandisiweyo kunye nokugcinwa okucuthiweyo Iibholiti ze-Dacromet hex rhoqo ukuzisa iindleko ezisezantsi zobomi kwiindawo ezinobungozi.

IsiKhokelo esiSebenzayo sabaQinisekisi

Xa ukhetha Iibholiti zehex ezigqunywe ngeDacromet, iinjineli kufuneka ziqinisekise ibakala lokugquma (umzekelo, iBanga A okanye B ngokobunzima bokugquma), ziqinisekise ukuhambelana kwayo nayiphi na i-lubricant ye-topcoat kunye nobudlelwane obucetyiweyo be-torque-tension, kwaye baqinisekise ukuba zombini iibholiti namandongomane/iiwasha ezihambelanayo zifumana ukugqibezela okuhambelanayo. Ukugcinwa ngokufanelekileyo kunye nokuphatha kuhlala kubalulekile: ngelixa iingubo ziphezulu anti-rust, umonakalo womatshini ngaphambi kokufaka unokunciphisa ukukhuselwa kwendawo.

Ukuqukumbela

Itekhnoloji yeDacromet ikhulile ukusuka kwinqwelomoya ekhethekileyo ukuya kwindawo eqhelekileyo anti-umhlwa isisombululo sokusebenza okuphezulu iibholiti zehex. Ukudityaniswa kwayo okukhethekileyo kokufana kwefilimu ebhityileyo, ukungabikho kwe-hydrogen embrittlement, amandla aphakamileyo obushushu, kunye nobungqina bokumelana nokutshiza kwetyuwa kangangeeyure ezingamawaka amaninzi njengokhetho oluphambili naphi na ixesha elide. umhlwa-ubungqina ukuthembeka akuxoxiswana.

Njengabanikazi beziseko ezingundoqo, abaphuhlisi beefama zomoya, kunye neeOEM zeemoto ziyaqhubeka nokubeka phambili ukuqina kunye nokugcinwa okucuthiweyo, Iibholiti ze-Dacromet hex kulindeleke ukuba babambe isabelo esandayo sentengiso ye-premium fastener-ukuhambisa anti-rust ukusebenza okufunwa yinjineli yanamhlanje.
