Kodi Chromate Conversion Coating/Alodine/Chem Film ndi chiyani?
Nthawi yowerenga mphindi 3
Mawu Oyamba
Chromate kutembenuka ❖ kuyanika amadziwikanso ngati ❖ kuyanika alodine kapena Chem filimu, ndi mtundu wa kutembenuka ❖ kuyanika ntchito passivate aluminiyamu, nthawi zina zitsulo, nthaka, cadmium, mkuwa, siliva, titaniyamu, magnesium, ndi malata aloyi amagwiranso ntchito.Njira ya passivation imapanga filimu yotetezera pamwamba pa katunduyo, yomwe imateteza ku dzimbiri.
Mosiyana ndi anodizing, zokutira kutembenuka kwa chromate ndi zokutira kutembenuka kwamankhwala.Muzitsulo zosinthika za mankhwala, mankhwala opangidwa ndi mankhwala amapezeka pamwamba pa zitsulo, ndipo mankhwalawa amasintha zitsulo kuti zikhale zotetezera.
Chophimba chosinthira chokha sichimayendetsa magetsi, chikagwiritsidwa ntchito molingana ndi Gawo 3 la muyezo wa MIL-DTL-5541.Zovala zosinthira mankhwala za Class 3 zimateteza ku dzimbiri komwe kumafunikira kukana kwamagetsi kochepa.Pankhaniyi, ❖ kuyanika palokha ndi sanali conductive, koma chifukwa kutembenuka ❖ kuyanika amakhala woonda, amapereka mlingo wina wa madutsidwe magetsi. kulumikizana ndi mainjiniya athukuti mudziwe zambiri pa izi.
Zovala za chromate ndizomwe zimagwiritsidwa ntchito kwambiri poteteza dzimbiri za Aluminium ndi Aluminium alloys kuchepetsa makutidwe ndi okosijeni pamwamba.Amagwiritsidwa ntchito kwambiriundercoat yopangira utoto kapena zomatirachifukwa cha zabwino zomangira zomwe zimapereka.
Zovala zosinthira chromate nthawi zambiri zimagwiritsidwa ntchito pazinthu monga zomangira, zida ndi zida.Nthawi zambiri amapereka mtundu wowoneka bwino, wachikasu wobiriwira kuzitsulo zoyera kapena zotuwa.

Kupaka Kutembenuza kwa Chromate Kuli Ndi Maubwino Ambiri
Kuphatikiza pa kutetezedwa kwa dzimbiri, palinso zabwino zambiri zogwiritsira ntchito zokutira zamakanema a chem kuphatikiza:
- Choyambira chabwino chothandizira utoto, zomatira ndi ma organic topcoats kumamatira
- Pewani zala zazitsulo zofewa
- Kugwiritsa ntchito mwachangu komanso kosavuta ndikumiza, kupopera kapena burashi
- Masitepe ocheperapo poyerekeza ndi njira zambiri zama mankhwala motero zimakhala zotsika mtengo komanso zotsika mtengo
- Perekani mgwirizano wodalirika wamagetsi pakati pa magawo
- Kupaka kopyapyala, pafupifupi kosayerekezeka, kotero sikumasintha magawo
Ngakhale nthawi zambiri zimagwirizanitsidwa ndi zokutira aluminium, zokutira zotembenuza chromate zitha kugwiritsidwanso ntchito ku cadmium, mkuwa, magnesium, siliva, titaniyamu ndi zinki.
Ndi mafakitale ati omwe angapindule pogwiritsa ntchito zokutira mafilimu amankhwala?
