Phosphating pretreatment mzere wa zitsulo kapena welded mbali

OURS COATING imapereka mizere yaposachedwa ya zida za phosphating pazigawo zachitsulo kapena zowotcherera zomwe zimagwiritsidwa ntchito mosiyanasiyana.

Kaya mukufunika kukonzanso mizere yakale, kapena mukufunika kugula yatsopano, ngakhale funsani zovuta zilizonse zaukadaulo, ingolumikizanani nafe, tidzakupatsirani njira imodzi yokha.

Mitundu ya Mizere ya Phosphate

● Iron phosphate

Iron phosphate ndiye njira yomwe imagwiritsidwa ntchito kwambiri popaka ufa chifukwa imatha kugwiritsidwa ntchito pafupifupi chilichonse ndipo imakhala ndi zinthu zomwe zimateteza chilengedwe kapena matope. Njirayi imagwiritsidwa ntchito kwambiri pazinthu zachitsulo.

● Zinc Phosphate

Zinc phosphate ndi zokutira zopanda zitsulo, za crystalline zomwe zimamatira kwambiri kuzinthu. Ndikofunikira kudziwa, zinc phosphate imachokera ku yankho lenilenilo, osati kuchokera kumtunda ngati zokutira zachitsulo. Makristalo a zinc phosphate amayamba kupangika pamalo amtundu wa anodic pagawo la pamwamba ndikusiya kupanga gawolo likadyedwa, mwachitsanzo. iwo anagunda kristalo wina. Mosiyana ndi chitsulo mankwala, nthaka mankwala sangathe kuyeretsa ndi odula pa nthawi yomweyo: Choncho, anayi siteji- kuchapa, nadzatsuka, nthaka mankwala, nadzatsuka ndi wamba khwekhwe. Ngakhale zinc phosphating imapereka zida zomata zomata bwino, zokutira bwino m'malo olimba komanso kukana kwa dzimbiri, njirayi imakhala ndi ndalama zambiri zogwirira ntchito, imagwiritsa ntchito zitsulo zolemera, ndipo imatha kupanga matope ambiri, omwe palibe omwe ali okonda zachilengedwe kuti awononge. Zinc phosphate nthawi zambiri amagwiritsidwa ntchito pazinthu zachitsulo.

● Chromium phosphate

Chromium phosphate imagwiritsidwa ntchito kwambiri pazigawo za aluminiyamu aloyi. Ngakhale kuti njirayi ndi yothandiza, monga zinc phosphate, imagwiritsa ntchito zitsulo zolemera zomwe zimafunika kubwezeredwa kuti ziwonongeke.

●Phosphate Process Controls

Kuwongolera njira ya phosphating ndikofunikira kuti mukwaniritse zokutira zokhazikika zomwe pamapeto pake zimabweretsa kukhazikika kokhazikika. Zowongolera zofunika kwambiri pakuwongolera kutembenuka kwa phosphate ndi:

Nthawi - nthawi yayitali yolumikizana ndi nthawi yochulukirapo yochita zinthu ndi mankhwala, njirayi iyenera kukhala yayitali mokwanira kuti chemistry ipange zokutira zofananira.

Kutentha - ma chemistries nthawi zambiri amakhala ankhanza kwambiri pakatentha kwambiri

Kukhazikika ndi pH - kuchulukitsitsa kwa asidi kumachulukitsa njira yokutira ndipo kumatha kupangitsa kuti zokutira zikhale zolemera kwambiri.
