Iterambere ryiterambere rya chrome yubusa dacromet irangi

Byoherejwe 2016-12-22Birazwi neza ko Dacromet ari igisubizo cyamazi gikwirakwizwa kigizwe na zinc flake, flake ya aluminium ninyongeramusaruro.Ibikorwa nyuma yo kwibiza no gutera, gukiza 20min kuri 80 ℃ mu ziko mbere yo gushyushya, 30min kuri 300 ℃ mugukiza itanura.Kora chromium ya hexavalent yari alcool adipic kandi kugabanuka kama mumazi ya dacromet ntago ashonga mumazi.
Twabibutsa ko kugabanya chromium ya hexavalent muri chromium trivalent hamwe na okiside ya chromium trivalent muri chromium ya hexavalent ni inzira ihinduka.Kubwibyo, mubikorwa byacumuye, chromium trivalent izakomeza kuba oxyde kuri chromium hexavalent, na chromium hexavalent ni kanseri, bityo guhura bizangiza ubuzima.Kubwibyo, gakondo ya chromium irimo ibishishwa ntabwo ari zeru zuzuye, mugihe cyose habaye chromium ya hexavalent, bizagira ingaruka runaka kubidukikije ndetse nabantu, kubwibyo, gukundwa na chrome yubusa ya Dacromet ni ngombwa.
Hamwe nimbaraga zigihugu zo kurengera ibidukikije zikomeje gushimangira, ibicuruzwa byinshi byimodoka bikenera chrome yubusa dacromet yubatswe.Ndetse yateje imbere chrome yubusa dacromet itwikiriye ibipimo bya tekiniki.Nka Volkswagen GMW3359, GM7111M nibindi
Chrome yubusa Dacromet irashaka cyane cyane ibindi bintu aho kuba aside ya chromic passivation no guhuza.Chrome yubusa ya Dacromet yubusa ikoresha cyane cyane silikoni kama, silikoni idasanzwe, molybdate, tungstate, fosifate nka binder, gukoresha kimwe cya scaly zinc / aluminium nkibintu byingenzi byuzuza, kandi binyuze murukurikirane rwa kashe Nyuma yubuvuzi, kugirango ugere kubintu byiza cyane Kurwanya ruswa hamwe na chromium irimo Dacromet.
Ubuhanga bwa Chrome bwubusa bwa Dacromet ntabwo bufite inyungu zikoranabuhanga rya chromium-dacromet gusa, ahubwo no muburyo bwo gutegura amarangi, gutwikira, firime, gutwikira ubwabyo nta chromium ihari, imyumvire nyayo yo kumenya icyatsi kibisi kitagira uburozi.Duhereye ku bidukikije, mu rwego rwisi yose ya chrome yubusa ya Dacromet aho kuba chrome dacromet icyerekezo rusange ntabwo kizahinduka, kizazana icyiciro gishya cyikoranabuhanga rirwanya ruswa murwego rwo guhindura ibidukikije.
