Zofunikira pakupaka ufa pakuthirira kotentha koviika
Mafotokozedwe otsatirawa akulimbikitsidwa: Gwiritsani ntchito zinc phosphate pretreatment ngati kumamatira kwambiri kumafunika. Pamwamba payenera kukhala paukhondo. Zinc phosphate ilibe zotsukira ndipo sizichotsa mafuta kapena nthaka. Gwiritsani ntchito iron phosphate ngati ntchito yokhazikika ikufunika. Iron phosphate imakhala ndi zotsukira pang'ono ndipo imachotsa kuipitsidwa pang'ono pamtunda. Zogwiritsidwa ntchito bwino pazinthu zopangira malata. Pre-kutentha ntchito isanayambe ntchito ufa. Gwiritsani ntchito zokutira za ufa wa 'degassing' kokha. Yang'anirani kuchiritsa koyenera ndi zosungunuliraWerengani zambiri …
Njira zothetsera mavuto a kupaka ufa pazitsulo zotentha za dip galvanizing
1. Kuchiza kosakwanira: Poliyesitala ufa wokutira ufa ndi utomoni wa thermosetting womwe umalumikizana ndi mawonekedwe awo omaliza posungidwa pa kutentha (nthawi zambiri 180 o C), kwa mphindi pafupifupi 10. Mavuni ochiritsira amapangidwa kuti apereke nthawi iyi pakuphatikiza kutentha. Ndi zinthu zotentha zothira malata, ndi makulidwe awo olemera a gawo, ndikofunikira kuwonetsetsa kuti nthawi yowotcha yokwanira imaloledwa kukwaniritsa zofunikira zakuchiritsa. Kutentha koyambirira kwa ntchito yolemetsa kumathandizira kufulumizitsa njira yochiritsiraWerengani zambiri …
