Tshaj tawm rau Xyoo 2019-03-11Cov khoom siv Dacromet plays lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no.Dacromet coatings kuj muaj ntau heev hauv kev tsim khoom, tab sis Dacromet txheej tsis tuaj yeem khaws cia ntawm qhov kub thiab txias.Vim li cas?Yog vim li cas yog tias muaj ntau qhov zoo hauv Dacromet thev naus laus zis uas tsoos plating tsis tuaj yeem sib tw, uas tau nrawm nrawm rau hauv kev lag luam thoob ntiaj teb.Tom qab ntau tshaj 20 xyoo ntawm kev txhim kho thiab kev txhim kho tas mus li, Dacromet thev naus laus zis tau tam sim no tsim cov txheej txheem kev kho saum npoo av, uas yog siv dav hauv kev kho corrosion ntawm hlau qhov chaw.Lub tuam txhab no tau tsim Nippon.Darro.shamrock (NDS) nyob rau hauv 1973 nrog Nyiv Roj & Fats Co., Ltd., thiab kuj tsim DACKAL nyob rau hauv cov teb chaws Europe thiab Fabkis nyob rau hauv 1976. Lawv muab faib lub ntiaj teb no ua lag luam rau plaub lub lag luam loj: Asia Pacific, Europe, Africa thiab Asmeskas.Lub luag haujlwm rau ib cheeb tsam thiab nrhiav kev txaus siab rau thoob ntiaj teb.Vim hais tias qhov kub siab dua, qhov ntau dua qhov kev laus ntawm cov kua txheej yog, qhov ntsuas kub ntawm Dacromet txheej cov kua yog zoo dua tswj hauv qab 10 ° C.Nyob rau tib lub sijhawm, nyob rau hauv lub hnub ci, cov kua txheej txheej yog yooj yim rau polymerize, metamorphose, thiab txawm scrapped, yog li nws yog qhov zoo tshaj kom khaws cia rau hauv qhov chaw txias.Lub sij hawm cia ntawm Dacromet txheej cov kua tsis yog ntev heev, vim hais tias lub sij hawm ntev ntawm cov txheej txheem khaws cia, qhov pH tus nqi yuav siab dua, uas yuav ua rau cov kua txheej txheej yuav muaj hnub nyoog thiab muab pov tseg.Qee qhov kev sim tau pom tias cov khib nyiab tom qab kev npaj ntawm chromium-dawb dacromet, cov kua siv tau rau 30 hnub ntawm 20 ° C, 12 hnub ntawm 30 ° C, thiab tsuas yog 5 hnub ntawm 40 ° C.Yog li, Dacromet txheej kua yuav tsum muaj nyob rau hauv qhov kub thiab txias, los yog qhov kub thiab txias yuav ua rau cov kua txheej rau hnub nyoog.
