1. Isingeniso kwi-Dacromet Hex Bolts

I-Dacromet hexagon bolts imele udidi oluphezulu lweziqhoboshi ezenzelwe ukuxhathisa okugqwesileyo kwe-corrosion kunye nokuthintela umhlwa ixesha elide. Ezi bholiti zidibanisa ukuthembeka komatshini wemigangatho ye-hexagonal-head bolts kunye ne-zinc-aluminium flake coating eyaziwa ngokuba yi-Dacromet (ekwabizwa ngokuba yi-Dacro okanye i-zinc-flake coating). Isiphumo yibholithi enikezela ukusebenza okugqwesileyo kokuchasene nomhlwa kwiindawo ezirhabaxa ngelixa igcina ijometri yentambo echanekileyo kunye namandla aphezulu okuqina.

Ngokungafaniyo ne-electro-galvanized or hot-dip galvanized bolts, iibholiti ze-Dacromet hexagon zisebenzisa inkqubo yokwambathisa engeyiyo eye-electrolytic. Oku kuphelisa umngcipheko we-hydrogen embrittlement-inzuzo ebalulekileyo kwiibhotshi eziphezulu zamabanga 8.8, 10.9, kunye ne-12.9. Ifilimu yeDacromet ebhityileyo, iyunifomu (ngokuqhelekileyo i-4-12 μm) inika ukuxhathisa okuphezulu kwetyuwa-spray, ukumelana nobushushu, kunye nokuqina okuchasene ne-rust jikelele, okwenza ezi bholithi zibe zikhetho ezikhethiweyo kwi-automotive, ukwakhiwa, amandla omoya, ulwandle, kunye nezicelo zezixhobo zoshishino.

2. Yintoni i-Dacromet Coating?

I-Dacromet yi-inorganic, itekhnoloji yonyango yesinyithi esekwe emanzini ebandakanya ubukhulu becala i-zinc flakes, i-aluminium flakes, kunye ne-chromium-based binders. Xa ifakwe kwi-hexagon bolt kwaye iphiliswe kwiqondo lobushushu eliphakamileyo (malunga ne-300 °C), iiflakes zilungelelaniswa kumaleko aqengqelekayo, zenze umqobo oshinyeneyo, wesinyithi owenziwe ngesilivere-ngwevu. Esi sakhiwo sinemigangatho emininzi senza zombini umqobo womzimba ngokuchasene nokufuma kunye ne-electrolytes kunye nedini lokhuseleko lwe-anodic oluchasa ngokusebenzayo ukubunjwa komhlwa.

Ukugquma kwi-Dacromet hexagon bolt inika ukhuseleko olubini: iiflakes ze-zinc zisebenza njenge-anode yedini, i-corroding ngokukhethekileyo ukukhusela i-substrate yentsimbi, ngelixa iiflakes ze-aluminium kunye ne-matrix ye-inorganic kwandisa iipropati zomqobo kunye nokuphucula ukuxhathisa ukubola. Ngenxa yokuba inkqubo ayinayo i-electrolytic, akukho hydrogen ingeniswe kwi-lattice yensimbi, igcina ingqibelelo epheleleyo yomatshini yeebholiti eziphezulu.

3. Inkqubo yeDacromet yokuNxibelela yeeBolts zeHexagon

Imveliso ye-Dacromet hexagon bolt ethembekileyo ilandela ulandelelwano olulawulwa ngononophelo lwenzelwe ukwandisa ukunamathela, ukufana, kunye nokusebenza okuchasene nokubola:

1.Ukulungiswa komphezulu: I-bolt ihlanjululwa ngokucokisekileyo kunye nokuchithwa komatshini okanye i-alkaline. Ukunyuswa kwe-Acid kuphetshwa ngamabom ukuthintela ukufunxwa kwe-hydrogen enokukhokelela ekugqityweni kweebholiti zamandla aphezulu.

2.Ukusetyenziswa koKugquma: Iibholiti ze-hexagon ezicociweyo zintywiliselwa, zitshizwe, okanye zicwiliswe kwi-Dacromet slurry esekelwe emanzini equlethe i-zinc kunye ne-aluminium flakes. I-Dip-spin yeyona ndlela ixhaphakileyo yoshishino yokusetyenzwa kwesambuku seebholiti.

3. Ukunyanga / Ukuhlambalaza: Iibholithi ezigqunyiweyo zibhakwa malunga ne-300 °C. Ngexesha lokunyanga i-binder iyaphendula kunye ne-metallic flakes sinter ibe yifilimu eqhubekayo, ebambelele ngokuqinileyo.

4.UHlolo lobulunga: Iibholiti ze-Dacromet zehexagon ezigqityiweyo zijongiwe ukutyeba, ukunamathela, ukubonakala, kunye nokusebenza kwetyuwa-spray ukuqinisekisa ukhuseleko olungaguqukiyo lokulwa nomhlwa.

4. Ukuthelekiswa kokuSebenza kwe-Anti-Corrosion Coatings

Le theyibhile ilandelayo ishwankathela umahluko ophambili phakathi kweebholiti ze-Dacromet zehexagon kunye neebholithi ezigqitywe ngeendlela zemveli zokuchasa umhlwa:
