Dacromet Hex Bolts: Superior Corrosion Resistance thiab Kev Ua Haujlwm Ntev Ntev 

3. Cov txheej txheem Dacromet txheej rau Hex Bolts

Kev tsim tawm ntawm Dacromet hex bolts ua raws li cov txheej txheem ua tib zoo tswj tsis-electrolytic uas ua kom muaj kev tiv thaiv ib puag ncig thiab tshem tawm hydrogen embrittlement txaus ntshai:

1. Kev npaj deg: Hex boltsraug ntxuav kom huv si kom tshem tau cov roj, roj, nplai, thiab cov kab mob kom paub tseeb tias qhov zoo tshaj plaws adhesion ntawm Dacromet

2.Coating daim ntawv thov: huv si boltsyog immersed nyob rau hauv dej-raws li slurry ntawm zinc thiab txhuas flakes nrog binders. Dip-spin los yog cov txheej txheem tshuaj tsuag kom ntseeg tau tias txawm tias txheej rau txhua qhov chaw ntawm hexagonal bolts, nrog rau threads thiab recesses.

3. Kev kho: Tom qab tshaj slurry raug tshem tawm, lub coated boltsyog ci ntawm kwv yees li 300 ° C. Lub inorganic binder solidifies thiab bonds cov zinc-aluminium flakes rau cov hlau, tsim kev tiv thaiv. Dacromet

4. Kev tshuaj xyuas: Tiav lawm Dacromet boltsyog kuaj rau txheej thickness, tsos, adhesion, thiab corrosion kuj. Kev xaiv topcoats tuaj yeem txhim kho lubricity lossis xim.

Vim lub Dacromet txheej txheem tsis muaj kua qaub pickling lossis electrolytic deposition, tsis muaj kev pheej hmoo ntawm hydrogen embrittlement. Qhov no ua rau Dacromet tshwj xeeb tshaj yog tsim rau high-strength hex bolts ntawm qib 8.8, 10.9, thiab 12.9.

4. Qhov tseem ceeb ntawm Dacromet Hex Bolts

Dacromet hex bolts xa ib qho kev sib xyaw ua ke ntawm cov txiaj ntsig kev ua tau zoo uas ua rau lawv sib nrug ntawm cov galvanized lossis plated bolts:

4.1 Zoo Corrosion Resistance

Qhov tseem ceeb tshaj feature ntawm Dacromet (Darcomet) yog nws qhov tshwj xeeb anti-corrosion muaj peev xwm. Txuj Dacromet coated bolts feem ntau ua tiav tshaj 1,000 teev ntawm ntsev tsuag tsis muaj xeb liab; Cov qib kev ua tau zoo tuaj yeem tshaj 2,000 teev. Piv nrog cov tsoos electro-galvanizing, Dacromet bolts muab 7 mus rau 10 npaug zoo dua kev tiv thaiv corrosion. Txawm nyob rau hauv cyclic corrosion tests thiab sulfur dioxide ib puag ncig, Dacromet hex bolts tswj kev ncaj ncees zoo heev.

4.2 Tsis muaj Hydrogen Embrittlement

Siab zog bolts yog qhov yooj yim rau hydrogen embrittlement thaum ua tiav los ntawm cov pa electroplating. Cov Dacromet txheej txheem kiag li zam qhov kev pheej hmoo no vim nws tsis yog-electrolytic. Vim li ntawd, Dacromet hex bolts ntawm cov qib siab tensile nyob ruaj ntseg thiab txhim khu kev qha nyob rau hauv load, ua rau lawv zoo tagnrho rau cov txheej txheem tseem ceeb thiab kev siv tsheb.

4.3 Kev Ua Haujlwm Kub Kub Zoo heev

Dacromet txheej txheej nyob ruaj khov ntawm qhov kub txog li 300 ° C lossis siab dua. Cov txheej txheem zinc txheej pib tawg lossis poob corrosion kuj kub ntawm 70-100 ° C thiab yuav poob ntawm 200-300 ° C. Piv txwv li, Dacromet coated bolts khaws ob qho tib si zoo li thiab kev tiv thaiv kev ua tau zoo nyob rau hauv lub sij hawm ntev-kub raug-muaj nuj nqis nyob rau hauv lub cav compartments, pa system, thiab cov khoom siv.

4.4 Superior Penetration thiab nyias zaj duab xis

Lub dip-spin daim ntawv thov ntawm Dacromet xyuas kom cov txheej nkag mus tob tob, xov, thiab qhov muag tsis pom ntawm hex bolts. Nrog ib tug raug thickness ntawm tsuas yog 6-10 μm, lub Dacromet zaj duab xis tsis ho hloov xov qhov ntev, cia Dacromet hex bolts yuav tsum tau siv nrog standard ceev. Qhov no siab permeability muab tiav anti-corrosion tiv thaiv txawm nyob rau hauv complex geometry.

4.5 Zoo Adhesion thiab Recoatability

Dacromet coatings adhere rau cov hlau substrate thiab txais cov organic topcoats ntxiv los yog xim zoo heev. Qhov yooj yim no txhawb kev sib txhuam coefficients thiab xim coding rau txawv series ntawm bolts.

5. Kev siv Dacromet Hex Bolts

Tsaug rau lawv superior corrosion kuj thiab kev ntseeg siab, Dacromet hex bolts tau piav qhia dav dav thoob plaws ntau qhov kev lag luam:

Automotive thiab kev thauj mus los: Chassis, ncua kev kawm ntawv, lub cev, thiab lub cav boltsxav tau lub sij hawm ntev anti-corrosion kev ua tau zoo nyob rau hauv txoj kev ntsev thiab huab cua raug.

Kev tsim kho thiab infrastructure: Kev tsim qauv boltsrau cov choj, yees, cov kab sib kis, thiab cov tsev nyob hauv ntug dej hiav txwv qhov twg Dacromet kev tiv thaiv ho txuas ntxiv kev pab cuam lub neej.

Marine thiab offshore: Hex boltssiv rau hauv nkoj, offshore platforms, thiab cov khoom siv chaw nres nkoj tau txais txiaj ntsig los ntawm qhov zoo tshaj plaws ntsev-txhaj tshuaj tiv thaiv ntawm Dacromet.

Renewable zog: Cua turbine yees thiab hnub ci mounting systems ntiav Dacromet coated boltsrau txhim khu kev qha sab nraum zoov kev tiv thaiv corrosion.

Industrial machinery: Siab zog boltsnyob rau hauv tshuaj nroj tsuag, tsim hluav taws xob, thiab cov tshuab hnyav cia siab rau Dacromet rau durability nyob rau hauv corrosive tej yam kev mob.
