Mabasa mana makuru e pretreatment mualuminium alloy surface kupedzisa

Kana aluminium extrusion mbiri ichipinda pa-saiti pretreatment panguva yekugadzira, iyo corrosion kuramba uye yekushongedza zvimiro zvealuminium pedenga inogona kuvandudzwa.

Basa rekutanga: Kuburikidza nemishonga yekukwesha pamusoro senge jecha uye makemikari etching, pretreatment inogadzira micro-rough chimiro pamusoro kuti igadzire mechini yekumisikidza nzvimbo dzekupotera poda. Kukasharara kwakakodzera kwepamusoro kunogona kuwedzera zvakanyanya mechanical anchoring mhedzisiro yemajasi.

Basa rechipiri: Kuburikidza nepamusoro activation marapirwo senge pickling uye alkaline etching, pretreatment inobvisa inert oxide layer pamusoro, inofumura simbi nyowani uye inovandudza pamusoro pemakemikari chiitiko. Chemical conversion coating treatment inoumba reactive conversion firimu pamusoro pekupa makemikari bonding nzvimbo dzekuputira. Kune aruminiyamu mbiri inoshandiswa mune imwe yepamusoro-yekupedzisira aruminiyamu profiles hwindo nemusuwo, maviri kana matatu anotevedzana epamusoro maitiro ekurapa anogona kudiwa.

Basa rechitatu: Pretreatment inokanganisa kunyorova uye kupindirana kwekubatana kwesimba pakati pekuputira uye substrate, uye zvakanyanya kunatsiridza kunyorova kwealuminium profiles.

Basa rechina: Firimu rekushandura kana mamwe akabatwa akaumbwa akaumbwa pamusoro pekutanga kuita senge interfacial transition layer, iyo inobvisa kushushikana kwekushushikana pakati pe substrate uye coating uye inowedzera iyo interfacial bonding simba.
