Txhua yam hlau raug rau huab cua ntev dhau los ua rau oxidize lub sijhawm. Tom qab xyoo dhau los ntawm kev ua pov thawj, Fasteners Engineering tau tsim thiab tsim cov kev kho mob uas muaj peev xwm daws tau qhov teeb meem ntawm oxidation ntawm bolts. Hauv qab no peb teev cov txheej txheem tsim khoom sib txawv siv thiab hloov kho raws li qhov xav tau ntawm peb cov neeg siv khoom.

Raws li ib qho ntawm cov fasteners tseem ceeb, screws feem ntau siv cov txheej txheem kev kho deg sib txawv kom tau raws li cov neeg siv khoom xav tau. Vam tias cov ntaub ntawv hauv qab no yuav muaj txiaj ntsig rau koj.

1. Zinc plating.

Galvanizing tuaj yeem muab faib ua txias galvanizing, mechanical galvanizing thiab kub galvanizing, uas kub galvanizing yog nrov tshaj plaws. Kub galvanizing, tseem hu ua kub-dip galvanizing, yog rau raus lub xeb tshem tawm steel qhov chaw rau zinc tov ntawm txog 500 ℃. Nyob rau hauv txoj kev no, qhov saum npoo ntawm lub workpiece yog txuas nrog zinc txheej, uas ua haujlwm rau lub hom phiaj ntawm kev tiv thaiv corrosion. Qhov zoo ntawm kub dip galvanizing yog raws li nram no:

• Muaj zog tiv thaiv corrosion.
• Zoo dua adhesion thiab hardness ntawm galvanized txheej.
• Tus nqi ntawm zinc yog loj, thiab lub thickness ntawm zinc txheej yog kaum ob lub sij hawm ntawm txias galvanizing.
• pheej yig dua thiab ntau tus phooj ywg environmentally.

2.Nto phosphating.

Surface phosphating yog ib qho pheej yig heev uas siv los ua primer ua ntej pleev xim.

• Lub hom phiaj tseem ceeb yog muab kev tiv thaiv rau cov hlau thiab tiv thaiv cov hlau los ntawm corroded mus rau ib qho twg.
• Txhim kho qhov adhesion ntawm xim zaj duab xis.
• Txo kev sib txhuam thiab lubrication thaum lub sij hawm hlau txias ua hauj lwm.

3.Dacromet yog ib hom tshiab ntawm cov txheej txheem tiv thaiv corrosion, uas yog cov cuab yeej zoo tshaj plaws los hloov cov tsoos electro-galvanizing thiab kub-dip galvanizing uas muaj cov pa phem ib puag ncig. Nws qhov zoo yog raws li nram no:

• Superior corrosion kuj: cov nyhuv xeb yog 7-10 npaug siab dua li cov tsoos galvanizing.
• Tsis muaj hydrogen embrittlement phenomenon, uas yog heev haum rau lub txheej ntawm stressed qhov chaw.
• Kev kub siab ua haujlwm, qhov kub tsis kam tiv thaiv tuaj yeem ncav cuag 300 ℃.
• Zoo adhesion thiab recoating kev ua tau zoo
• Tsis muaj dej khib nyiab thiab cov pa khib nyiab yuav raug tsim tawm thaum lub sijhawm tsim khoom.

4. Kab ntsig

Ruspert yog ib hom txheej uas tsim los rau kev tsim kho screws, ib puag ncig tus phooj ywg txheej tsim tom qab Dacromet. Piv nrog rau Dacromet, qhov zoo ntawm ruspert yog raws li nram no:

• Muaj zog corrosion kuj, tuaj yeem tiv taus ntsev tshuaj ntsuam rau 500-1500 teev
• Txheej tawv dua
• Qhov zoo ntawm qhov chaw tiav thiab adhesion
• Ntau xim muaj

DD Fasteners muaj 20 xyoo ntawm kev tsim khoom thiab kev muag khoom.
