Dacromet (kev kho deg technology):
Dacromet yog tus txhais lus thiab luv luv ntawm DACROMET, abbreviated li Dacromet, Dacromet, thiab Dirkron. Nws yog lub npe hu ua zinc-chromium txheej hauv Suav teb. Nws yog ib hom tshiab zinc hmoov, txhuas hmoov, chromic acid thiab deionized dej ua cov khoom tseem ceeb. Anti-corrosion txheej.
Dacromet tau yug los thawj zaug hauv 1950s lig. Nyob rau lub caij ntuj no txias hauv North America thiab Northern Europe, cov dej khov tuab ntawm txoj kev ua rau muaj kev cuam tshuam loj rau kev tsav tsheb. Cov neeg siv ntsev nchuav rau hauv av kom txo qhov kub ntawm qhov chaw txias kom txo tau qhov teeb meem ntawm txoj kev du, tab sis cov sodium chloride uas tuaj tom ntej Cov tshuaj chlorine ions eroded cov hlau matrix, cov tsheb thauj mus los tau raug mob hnyav, thiab teeb meem loj tshwm sim. Tus kws tshawb fawb Asmeskas Mike Martin tau tsim cov xim uas muaj dej-soluble ntau heev raws li cov hlau zinc flakes thaum ntxiv aluminium flakes, chromic acid, thiab dej deionized ua cov kuab tshuaj. Nrog rau cov txheej nyias nyias, Dacromet txheej tau ua tiav kev tiv thaiv corrosion ntawm chloride ions, thiab cov cuab yeej tiv thaiv corrosion tau nkag mus rau theem tshiab, tsim kho qhov tsis txaus ntawm cov txheej txheem ntawm kev tiv thaiv lub neej.
Yog li ntawd, Dacromet thev naus laus zis tau txais los ntawm Asmeskas tub rog ua cov cuab yeej tiv thaiv kev ua tub rog (US tub rog tus qauv MTL-C-87115). Los ntawm xyoo 1970, lub tuam txhab Nyij Pooj NDS tau qhia Dacromet thev naus laus zis los ntawm Asmeskas lub tuam txhab MCI, thiab Nws tau yuav tawm txoj cai los siv nws hauv thaj av Asia-Pacific thiab tau koom tes tswj hwm hauv MCI Corporation ntawm Tebchaws Meskas. Lub teb chaws cov kob Nyij Pooj muaj qhov loj corrosion tonnage ntawm steel qhov chaw txhua xyoo, yog li nws them tshwj xeeb rau kev siv tshuab los tiv thaiv corrosion. Tom qab Dacromet thev naus laus zis tau txhim kho los ntawm Nyij Pooj, ntau tshaj 100 txheej cov nroj tsuag thiab ntau dua 70 chav tshuaj tau tsim kho sai hauv Nyiv. Qee lub tebchaws tsim kho kuj tau qhia txog Dacromet thev naus laus zis. Tuam Tshoj tau tshaj tawm Dacromet thev naus laus zis los ntawm Nyij Pooj xyoo 1994. Nws tau pib tsuas yog siv hauv kev lag luam tiv thaiv thiab cov khoom siv hauv cheeb tsam, thiab tom qab ntawd tau tsim los rau hauv hluav taws xob fais fab, kev tsim kho, marine engineering, khoom siv hauv tsev, khoom siv kho vajtse thiab cov qauv, railways, txuas hniav, Tunnels, kev loj guardrails, petrochemicals, bioengineering, cov khoom siv kho mob hmoov metallurgy thiab lwm yam lag luam.
Qhov 2 Brass Ball Valve no tsuas yog ib qho ntawm Brass Ball Valve 81065, thiab ib qho ntawm lawv muaj kev tuav nrog Dacromet plating nto kho tshuab.
