Bakeng sa li-fasteners tsa likoloi, kalafo ea holim'a metsi ha se qeto feela ea ho se mamelle{0} Theko e ka ama friction, torque{2}}boits'oaro ba tsitsipano, dimensional fit, hydrogen embrittlement risk, le{3}nako e telele ea ho sebetsa ha kopanelo.
Mekhoa e 'meli ea ho roala e atisang ho nahanoa bakeng sa likopo tse hlokang likoloi keZinc-Nickel le Dacromet. Ka bobeli li ka fana ka maemo a phahameng a ts'ireletso ea kutu, empa li sebetsa ka tsela e fapaneng 'me li loketse litlhoko tse fapaneng tsa kopo.
Bakeng sa baenjiniere, potso e nepahetseng ha se hore na ho roala ho molemo ho feta hohle. Ke eona tsamaiso ea ho roala e fanang kae hloka ts'ireletso ea kutu, boitšoaro ba likhohlano, taolo ea boholo, le ts'ebetso ea tlhahiso bakeng sa lenonyeletso le ikhethileng.
Zinc-Nickel le Dacromet Rarolla Litlhoko tse Fapanong tsa Coating
Papiso e sebetsang ka ho fetisisa e qala ka kopo ea sebele ho e-na le letšoao la ho roala.
Zinc-Nickel ke zinki e entsoeng ka electroplated{1}}alloy coating, ha Dacromet e le ea lelapa la -electrolytically applied zinki{3}}lisebelisoa tsa li-flake coating.
Phapang ena ea mokhoa oa ho roala e ama tsela eo fastener e itšoarang ka eona nakong ea tlhahiso le tšebeletso.
Zinc-Liaparo tsa nickel hangata li khethoa ha likoloi li hloka tšireletso e matla ea kutu hammoho le botenya bo laoloang le tsamaiso e itseng ea likhohlano..Dacromet, joalo ka zinc-flake system, hangata e nkuoa e le li-fasteners tse phahameng-moo ho hanyetsanang le corrosion le hydrogen{2}}embrittlement control li leng bohlokoa.

KaAYA Fasteners, o ka khona ho etsa li-fasteners tsa likoloi ka lisebelisoa tse fapaneng, limaraka tsa matla, le kalafo ea bokaholimo, kahoo o ka nahana ka litlhoko tsa ho roala ka moralo oa fastening ho fapana le ho li nka e le mohato o arohaneng.
Moo Zinc-Nickel e Kenang Le Likopo tsa Automotive Fastener
Zinc-Nickel e bohlokoa haholo ha tšireletso ea kutu le likarolo tse laoloang tsa bokaholimo li hloka ho leka-lekana le litlhoko tsa kopano ea likoloi.
Bokahare ba nickel bo fetola sebopeho sa "zinc{0}based coating", athe mokhoa oa ho qetela oa ho roala o ka kopanngoa le likhoele tse fetotsoeng, li-sealer kapa mafura ho fihlela katleho.ts'ebetso e hlokahalang ea corrosion le khohlano.
Bakeng sa lisebelisoa, lintlha tsa bohlokoa li kenyelletsa:
- Ho hlokahala khanyetso ea kutu tlas'a tikoloho ea sebele ea tšebeletso
- Botenya ba ho roala le khoele e lekanang
- Litlhoko tsa torque{0}}
- Ho tsitsana ha coefficient
- Taolo ea hydrogen embrittlement bakeng sa-lihatla tsa tšepe tse matla
- Ho lumellana le lisebelisoa tse potolohileng le mokhoa oa ho kopanya
Zinc-Nickel e ka ba khetho e sebetsang ha kopo e hloka mokhoa o laoloang oa ho roala ka motlakase ho e-na le ho fana ka sephetho sa letsoai se phahameng ka ho fetesisa{1}}.
Ha u sebelisa customizedliboutu tsa likoloi, khetho ea ho roala e lokela ho hlahlojoa hammoho le geometry ea khoele, litekanyo le litlhoko tse tiisang.
Ha Dacromet e Utloisisa Haholoanyane
Dacromet ha se-electrolytic zinc{1}}seseteme ea ho roala flake. Ho fapana le electroplating, e sebetsa ho roala ntle le mokhoa oa ho beha electrolytic.
Sena se etsa hore zinc-li-flake system li be tsa bohlokoa ka ho khetheha bakeng sa-li-fasteners tsa tšepe tse matla, moo likotsi tse amanang le hydrogen{2}} tse amanang le electroplating li tlamehang ho laoloa ka hloko.
Dacromet e ka boela ea fana ka tšireletso e phahameng ea kutu e nang le lisebelisoa tsa ho roala tse batlang li le tšesaane, ha litlolo kapa li-topcoats li ka sebelisoa ho laola likhohlano le lisebelisoa tse ling tse sebetsang.
Bakeng sa lits'ebetso tsa likoloi, Dacromet e kanna ea nahanoa ha fastener e hloka:
Khanyetso e phahameng ea kutu
E thusa bakeng sa likarolo tse pepesehileng mongobo, letsoai la tseleng, kapa libaka tse ling tse senyang.
