The difference between galvanized bridge and hot-dip galvanized bridge

Igwe mmiri galvanized:

Akwa galvanized, nke a makwaara dị ka àkwà mmiri galvanized eletrik; N'ozuzu ghọtara dị ka galvanized àkwà mmiri nke na-ekpo ọkụ-mikpu galvanized akwa, n'ezie, ọ bụ ihe ọjọọ, dị ka galvanized ọkpọkọ, galvanized àkwà mmiri na-ekewa n'ime abụọ ụdị, ya bụ, oyi galvanized (electric galvanized) na na-ekpo ọkụ itinye galvanized (na-ekpo ọkụ-mikpu galvanized galvanized). );

2) The zinc oyi akwa nwetara site electroplating dị ọcha na corrodes nwayọọ nwayọọ na acid na alkali fog, nke nwere ike n'ụzọ dị irè na-echebe ígwè matrix;

3) Zinc mkpuchi kpụrụ site chromic acid passivation ọcha, agba, agha akwụkwọ ndụ akwụkwọ ndụ, mara mma, nwere ụfọdụ ji achọ;

4) N'ihi na mkpuchi zinc nwere ezigbo ductility, ọ nwere ike ịbụ oyi na-acha oyi, na-atụgharị, na-ehulata na ihe ndị ọzọ na-eme ka ọ ghara imebi mkpuchi ahụ.

Akwa akwa galvanized na-ekpo ọkụ(akwa akwa zinc na-ekpo ọkụ)

1, nkọwa zinc dị ọkụ:

Zinc na-ekpo ọkụ bụ otu n'ime ụzọ mkpuchi kachasị mma maka ichekwa mkpụrụ nchara. Ọ bụ na mmiri mmiri steeti zinc, mgbe nnọọ mgbagwoju anụ ahụ na kemịkalụ edinam, ọ bụghị naanị na ígwè plating thicker dị ọcha zinc oyi akwa, kamakwa n'ịwa a zinc – ígwè alloy oyi akwa. Usoro plating a abụghị naanị nwere njirimara nke nguzogide corrosion nke galvanizing, kamakwa ọ nwekwara akwa akwa zinc-iron. Ọ nwekwara ike na-eguzogide corrosion nke enweghị ike iji ya tụnyere galvanizing.

2) ion zinc na alloy oyi akwa na-agbasawanye na matriks iji mepụta akwa akwa zinc-iron;

3) N'elu ihe mkpuchi alloy na-ekpuchi akwa zinc.

3. Njirimara arụmọrụ:
