I-Dacromet Hexagonal Bolts-Ii-Anti-Corrosion ephucukileyo kunye ne-Anti-Rust Fastening Solutions 

2. Yintoni i-Dacromet Coating?

I-Dacromet yinkqubo yokugquma i-zinc-aluminiyam ye-flake ephuhliswe njengenye indlela ehamba phambili kwi-electroplating eqhelekileyo. Ukwaleka kuqulathe iiflakes ze-zinc ezidityanisiweyo kunye neeflakes ze-aluminiyam kwi-inorganic binder. Xa igalelwe kwiibholithi ezimacala mathandathu kwaye yanyangwa malunga ne-300 ° C, yenza umqobo oshinyeneyo, onamaleko amaninzi onikezela ngokubalaseleyo. anti-rust kwaye anti-umhlwa ukusebenza.

Iimpawu eziphambili zeDacromet zokugquma kwiibholiti:

• Ifilimu encinci: Ngokuqhelekileyo kuphela i-4-12 μm (ihlala i-6-8 μm), igcina i-geometry yomsonto kwaye ifaneleke kwiibholiti ezine-hexagonal ezichanekileyo.
• Umqobo + ukhuseleko lombingelelo: I-zinc ene-laminated kunye ne-aluminium flakes ivimba ukufuma / i-oksijeni kwaye inikezela ngokhuseleko lwe-galvanic (lomnikelo) we-substrate yensimbi.
• Ukhuseleko olufanayo: I-Dip-spin okanye isicelo sokutshiza siqinisekisa ukugquma okugqwesileyo kwijometri entsonkothileyo, kubandakanywa nemisonto enzulu kunye nentloko ene-hexagonal.
• Imbonakalo: Ukugqitywa okufanayo kwesilivere-grey matte, ilungele ukusetyenziswa okusebenzayo kunye nobuhle.

3. Izinto eziluncedo eziphambili zeDacromet Hexagonal Bolts

Ukuxhathisa okugqwesileyo kokuRhakala kunye nokusebenza okuchasene nomhlwa

Inzuzo ephambili ye-Dacromet-coated hexagonal bolts ibalaseleyo ukumelana nomhlwa kunye nexesha elide anti-rust ubunakho. Nangona i-coating ebhityileyo ye-4-8 μm kuphela, ezi bholiti zihlala zixhathisa ukuvavanywa kokutshiza kwetyuwa engathathi hlangothi (ASTM B117 / ISO 9227) ngaphezulu kweeyure ze-1,000-kwaye ngokufuthi i-1,200 ukuya kwiiyure ezingama-2,000-ngaphandle komhlwa obomvu. Oku kuqhelekile ka-7-10 ngokuphindwe ka-7 kune-electro-galvanizing yesiqhelo (iiyure eziyi-100-300) kwaye iyakhuphisana okanye iphezulu kunezingqinisiso ezininzi ezishinyeneyo zediphu eshushu.

I-multi-layer zinc-aluminiyam i-flake isakhiwo ibhloka ukufuma, i-oksijini, kunye neekloridi. Nokuba yonakele ekuhlaleni, isenzo sedini se-zinc siyaqhubeka nokukhusela i-bolt substrate, siphucula ngokubanzi. ukuthintela umhlwa. Oku kwenza i-Dacromet hexagonal bolts ilungele unxweme, ulwandle, i-automotive underbody, kunye neendawo zemizi-mveliso.

Zero Hydrogen Embrittlement Risk

Inzuzo ebalulekileyo ye-hexagonal bolts yamandla aphezulu kukungabikho ngokupheleleyo komngcipheko we-hydrogen embrittlement. I-Electroplating yazisa i-athomu ye-hydrogen kwintsimbi, enokubangela ukulibaziseka kwe-brittle fracture kumabakala 10.9, 12.9, kunye neebholiti zesakhiwo ezifana ne-ASTM A490. I-Dacromet ayinayo i-electrolytic kwaye inqanda ukunyuswa kwe-asidi enobudlova, ngoko akukho hydrogen yaziswa. I-Dacromet yamandla aphezulu iibholiti ngoko ke akufuneki ukubhaka kwe-post-plating kwaye unikeze ukuthembeka okuphezulu kwiindawo ezikhuselekileyo zokhuseleko. Ii-OEM ezininzi zeemoto zichaza i-Dacromet okanye i-zinc-flake efanayo yokwaleka ngenxa yesi sizathu.

Ukumelana nobushushu obuphezulu

Iingubo zeDacromet zigcina ingqibelelo kunye anti-umhlwa ukusebenza kumaqondo obushushu aqhubekayo ukuya kuthi ga kwi-300°C. I-zinc electroplating eqhelekileyo iyancipha ngaphezu kwe-100-120 ° C, ngelixa i-galvanizing eshushu-dip inemida ephantsi ephezulu. Olu uzinzo lwe-thermal lufanelana ne-Dacromet hexagonal bolts zamagumbi enjini, iinkqubo zokukhupha, ii-oveni zoshishino, kunye nezixhobo zokuvelisa amandla apho zombini i-clamping force kunye nexesha elide. ukuthintela umhlwa ziyafuneka.

4. Uthelekiso lweNtsebenzo

Itheyibhile engezantsi ithelekisa iDacromet kunye nezinye iindlela zokwaleka eziqhelekileyo ezisetyenziswa kwiibholiti ezinehexagonal:

Uluhlu loku-1. Iindidi zomgangatho wokusebenza oqhelekileyo wokwaleka kwiibholiti zentsimbi ezinehexagonal. Iziphumo ezizizo ziyahluka ngokwenkqubo yeeparamitha kunye nobukhulu.

5. Izicelo eziqhelekileyo

Enkosi kwabaphezulu anti-umhlwa, anti-rust, ukumelana nobushushu, kunye nenkululeko kwi-hydrogen embrittlement, i-Dacromet hexagonal bolts isetyenziswa ngokubanzi kwi:

5.1 Ishishini leeMoto

Amalungu eChassis, iinkqubo zokunqunyanyiswa, iindibano zebrake, ukunyuswa kwe-injini, kunye nokusetyenziswa kwe-underbody. Ezi iibholiti kufuneka ixhathise ityuwa yendlela, ukufuma, ukukhwela ibhayisekile eshushu, kunye nokungcangcazela. Ukungabikho kwe-hydrogen embrittlement kubaluleke kakhulu kwibanga eliphezulu le-10.9 kunye ne-12.9 fasteners kwiindawo ezinxulumene nokhuseleko.

5.2 Ulwakhiwo, ulwakhiwo kunye nobunjineli obunzima

Iibhulorho, izakhiwo zentsimbi, iinqaba zothumelo, iiinjini zomoya, kunye noomatshini abanzima bafuna ixesha elide ukumelana nomhlwa. Iibholiti ze-Dacromet ze-hexagonal zihambisa ezinokuthenjwa ukuthintela umhlwa ngaphandle kunye nakwiimeko ezingqongileyo zonxweme ngelixa ugcina ukufaneleka okuchanekileyo kunye nokusebenza okuphezulu.

5.3 IiNdawo zaseLwandle, ezingaselunxwemeni kunye nezeMichiza

Isitshizi setyuwa, ukufuma okuqhubekayo, kunye nokuba sesichengeni kweekhemikhali kufunwa kakhulu anti-umhlwa ukusebenza. I-Dacromet-coated-coated hexagonal bolts isebenza kwizixhobo ze-shipboard, iiplatifti ezingaselunxwemeni, iziseko zezibuko, kunye ne-process-plant fasteners apho iingubo eziqhelekileyo ze-zinc zisilela ngokukhawuleza.

5.4 Okunye ukuSetyenziswa kwemizi-mveliso

Amacandelo kaloliwe, izixhobo zolimo, izixhobo zokuvelisa amandla, kunye noomatshini bemizi-mveliso ngokubanzi bonke bayazuza ngokudityaniswa kwamandla oomatshini, ukuchaneka komda, kunye nokuqina. anti-rust ukhuseleko olunikezelwa yi-Dacromet hexagonal bolts.

6. Isiphelo

Iibholiti ze-Dacromet zehexagonal zibonelela ngesisombululo sepremiyamu yezicelo ezifuna ukusebenza komatshini okuphezulu kunye nokugqwesa. anti-umhlwa kwaye anti-rust ukhuselo. Ngokumelana nokutshizwa kwetyuwa ehlala igqitha kwiiyure ezili-1,000, umngcipheko we-hydrogen embrittlement eyi-zero, ukuxhathisa ubushushu ukuya kuma-300 ° C, kunye nokhuselo olubhityileyo olugcina umsonto ufanelekile, iDacromet-coated. iibholiti ukoyisa imida yokwalekwa kwe-zinc yemveli kwaye rhoqo ukodlula ukugalela okushushu kwediphu kwiindawo ezibalulekileyo.
