1. Taw qhia rau Dacromet Hex Bolts

Dacromet hexagon bolts sawv cev rau cov chav kawm ua haujlwm siab ntawm cov fasteners engineered rau tshwj xeeb corrosion tsis kam thiab tiv thaiv xeb mus ntev. Cov bolts no muab cov neeg kho tshuab kev ntseeg siab ntawm tus qauv hexagonal-lub taub hau bolts nrog cov txheej txheem zinc-aluminium flake txheej hu ua Dacromet (tseem hu ua Dacro lossis zinc-flake txheej). Qhov tshwm sim yog lub ntsia liaj qhov rooj uas xa cov kev ua tau zoo los tiv thaiv corrosion nyob rau hauv ib puag ncig hnyav thaum khaws cia cov xov geometry thiab lub zog tensile siab.

Tsis zoo li cov pa electro-galvanized lossis kub-dip galvanized bolts, Dacromet hexagon bolts siv cov txheej txheem tsis-electrolytic txheej. Qhov no tshem tawm txoj kev pheej hmoo ntawm hydrogen embrittlement-ib qho txiaj ntsig tseem ceeb rau lub zog muaj zog ntawm qib 8.8, 10.9, thiab 12.9. Dacromet zaj duab xis nyias nyias (feem ntau yog 4-12 μm) muab cov tshuaj ntsev-txhaj tshuaj tiv thaiv zoo, tiv thaiv tshav kub, thiab kev tiv thaiv xeb tag nrho, ua rau cov bolts nyiam xaiv hauv tsheb, kev tsim kho, cua zog, marine, thiab kev siv khoom siv.

2. Dacromet Txheej yog dab tsi?

Dacromet yog ib qho inorganic, dej-raws li hlau nto kho technology uas muaj feem ntau ntawm ultra-fine zinc flakes, txhuas flakes, thiab chromium-raws li binders. Thaum siv rau lub hexagon ntsia liaj qhov rooj thiab kho ntawm qhov kub thiab txias (kwv yees li 300 ° C), cov flakes ua ke mus rau hauv ntau txheej txheej, ua kom tuab, xim hlau nyiaj-grey barrier. Cov txheej txheem ntau txheej no ua rau ob qho tib si lub cev tiv thaiv kev ya raws thiab electrolytes thiab kev txi anodic tiv thaiv mechanism uas nquag tiv thaiv xeb tsim.

Cov txheej txheej ntawm Dacromet hexagon bolt muaj kev tiv thaiv dual: zinc flakes ua raws li kev txi anode, corroding nyiam los tiv thaiv cov hlau substrate, thaum lub txhuas flakes thiab inorganic matrix txhim kho cov khoom thaiv thiab txhim kho kev tiv thaiv corrosion. Vim tias cov txheej txheem tsis yog-electrolytic, tsis muaj hydrogen nkag mus rau hauv cov hlau lattice, khaws cia tag nrho cov neeg kho tshuab kev ncaj ncees ntawm cov bolts muaj zog.

3. Dacromet txheej txheej rau Hexagon Bolts

Kev tsim cov kev txhim khu kev qha Dacromet hexagon ntsia liaj qhov rooj ua raws li kev tswj xyuas kom zoo ib ntus tsim los ua kom muaj qhov adhesion, uniformity, thiab anti-corrosion kev ua tau zoo:

1. Kev Npaj Nto: Lub ntsia liaj qhov rooj tau txais kev tu thiab kho txhua yam los yog alkaline derusting. Acid pickling yog txhob txwm zam los tiv thaiv hydrogen nqus dej uas tuaj yeem ua rau embrittlement ntawm high-strength bolts.

2.Coating daim ntawv thov: Cov hexagon bolts uas huv si tau muab tso rau hauv, txau nrog, lossis dip-spun hauv Dacromet slurry uas muaj zinc thiab txhuas flakes. Dip-spin yog txoj kev lag luam tshaj plaws rau kev ua ntau ntawm bolts.

3.Curing / Sintering: Coated bolts yog ci ntawm kwv yees li 300 ° C. Thaum kho cov binder reacts thiab cov hlau flakes sinter rau hauv ib qho kev nruam, nruj adherent inorganic zaj duab xis.

4.Kev soj ntsuam zoo: Ua tiav Dacromet hexagon bolts raug tshuaj xyuas rau txheej thickness, adhesion, tsos, thiab ntsev-txhaj tshuaj ua tau zoo los lav kev tiv thaiv kev tiv thaiv xeb.

4. Kev sib piv ntawm Kev Tiv Thaiv-Corrosion Coatings

Cov lus hauv qab no qhia txog qhov sib txawv tseem ceeb ntawm Dacromet hexagon bolts thiab bolts tiav nrog cov txheej txheem los tiv thaiv xeb:
