Ebisara na 2018-11-12Ihe mkpuchi dacromet, nke a makwaara dị ka mkpuchi flake zinc, nwere uru na enweghị ike nweta nke ikpeazụ ma e jiri ya tụnyere usoro electro galvanized na-ekpo ọkụ na-ekpo ọkụ.Ihe mkpuchi nke zinc flake nwere uru ndị a:
#1.Nguzogide corrosion pụrụiche
Ihe nchebe electrochemical nke a na-achịkwa nke zinc, mmetụta mkpuchi nke zinc / aluminum sheets na nrụzi onwe onye nke chromate na-eme ka mkpuchi Dacromet na-eguzogide nke ukwuu mgbe a na-anwale mkpuchi Dacromet na nnu nnu na-anọpụ iche.Ọ na-ewe ihe dị ka 100 awa iji etch mkpuchi 1um, nke bụ 7-10 ugboro karịa ọgwụgwọ galvanizing omenala.Nnwale ịgba mmiri nnu na-anọpụ iche nwere ike ịdịru ihe karịrị awa 1000 (ihe mkpuchi nwere ọkpụrụkpụ nke 8um ma ọ bụ karịa), na ụfọdụ dị elu karịa, nke a agaghị ekwe omume na akwa galvanized na nke na-ekpo ọkụ.
#2.Magburu onwe okpomọkụ na-eguzogide
Ebe ọ bụ na Dakoro-coated chromic acid polymer enweghị mmiri kristal na ebe mgbaze nke aluminom / zinc mpempe akwụkwọ dị elu, mkpuchi ahụ nwere ezigbo ihe mgbochi corrosion dị elu.Ihe mkpuchi Dacromet nwere okpomọkụ na-eguzogide okpomọkụ nke 300 Celsius C. Enwere ike iji ya na-aga n'ihu ruo ogologo oge na 250 Celsius C. Nkwụsị nke corrosion ya fọrọ nke nta ka ọ ghara emetụta ya, na ihe nkiri passivation n'elu akwa akwa zinc electroplated na-ebibi na gburugburu. 70 Celsius C, na nguzogide corrosion bụ ọdịda dị nkọ.
#3.Ọ dịghị hydrogen brittleness
N'oge ọgwụgwọ teknụzụ nke Dacromet, ọ dịghị ịsacha acid, electrodeposition, eletriki de-oiling, wdg, ọ dịghịkwa mmeghachi omume electrochemical nke hydrogen evolushọn kpatara site na electro-galvanizing usoro, ya mere, ihe agaghị eme ka hydrogen embrittlement.Ya mere ọ dị mma karịsịa maka ijikwa akụkụ na-agbanwe agbanwe na ike dị elu workpieces.
#4.The goodrecoatability
Ọdịdị nke mkpuchi Dacromet bụ ọlaọcha-agba ntụ na-ejikọta nke ọma na mkpụrụ na mkpuchi dị iche iche.Enwere ike iji ya dị ka oyi akwa dị n'elu ma ọ bụ dị ka primer maka mkpuchi dị iche iche.Mmeghachi omume electrochemical na-eme n'etiti ọla n'ihi ọdịiche nwere ike ime.N'ihi na galvanized n'ígwé, ma ígwè dabeere na aluminum n'ígwé na-electrochemically eguzogide ma na-ebelata corrosion iguzogide.Maka Dacromet mgbochi corrosion oyi akwa, ebe ọ bụ na mgbochi corrosion na-adabere na chromic acid passivation na nchebe ịchụ àjà a na-achịkwa nke oyi akwa zinc scaly, ọ dịghị electrochemical corrosion na-emepụta, ya mere, oriri Zn na-ebelata corrosion nke Al.
#5.Permeability dị mma
Mmiri ọgwụgwọ Dacromet nwere ike ịbanye na nkwonkwo siri ike nke workpiece iji mepụta mkpuchi nchara.Ọ bụrụ na a na-eji usoro electroplating eme ihe, elu ime nke onye òtù tubular adịghị edozi ya n'ihi mmetụta nchebe.Otú ọ dị, n'ihi na a na-eji ọgwụgwọ Dacromet eme ihe site na mkpuchi ma nwee ezigbo permeability, enwere ike itinye ya iji meziwanye ikike mgbochi nchara n'ime na n'èzí.
#6.Enweghị mmetọ
Mgbe electroplating zinc, e nwere nsogbu nke nsị nsị nwere zinc, alkali, chromic acid, wdg, nke ga-eme ka nnukwu mmetọ.Okpomọkụ nke zinc dip na-ekpo ọkụ dị elu, na zinc vapor na HCL ewepụtara na-emerụ ahụ ike mmadụ.Ọtụtụ n'ime mmepụta zinc okpomọkụ dị ugbu a ga-emerịrị site na obodo mepere emepe na ime obodo.Usoro Dacromet emepụtala ubi ọhụrụ nke nchedo corrosion metal.N'ihi na ọgwụgwọ Dacromet bụ usoro mechiri emechi, ihe ndị na-agbanwe agbanwe n'oge a na-eme achịcha bụ mmiri, enweghị ihe ndị ọzọ na-emerụ ahụ nke a na-achịkwa, na enweghị mmetọ na gburugburu ebe obibi.
