Njira zothetsera mavuto a kupaka ufa pazitsulo zotentha za dip galvanizing

1. Kuchiza kosakwanira:

• Polyester poda kupaka ufa ndi thermosetting resins yomwe imalumikizana ndi mawonekedwe awo omaliza posungidwa kutentha (nthawi zambiri 180 o C), kwa mphindi 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 yochiritsa mu uvuni wochiritsira.

2.Kusakhazikika bwino:

• Gawo lomaliza la kutsekemera kwa diyi wotentha limaphatikizapo kuzimitsa kwa madzi a ntchitoyo, nthawi zambiri mu njira yofooka ya sodium dichromate. Izi zimaziziritsa ntchitoyo kuti igwire ntchito ndikudutsa pamwamba pa zokutira zamagalasi kuti zisawonongeke msanga pamtunda. Kukhalapo kwa filimu yodutsa pamwamba pa zokutira zokometsera kumasokoneza zinc phosphate kapena iron phosphate pretreatment, ndipo nthawi zambiri, kumapangitsa kuti mankhwalawa asagwiritsidwe ntchito. Ndikofunikira kuti zinthu zamalati za divi zotentha zisazimitsidwe mukatha kukolezera. Izi zimatsimikizira kuti nthaka ya zinki imakhala yokhazikika kwambiri kuti ivomereze kukonzedweratu komwe kumagwiritsidwa ntchito popaka ufa.

3.Kuwongolera:

• Pinholing imayamba chifukwa cha mapangidwe ang'onoang'ono a mpweya mu zokutira za poliyesitala panthawi ya stoving / kuchiritsa. thovu izi kupanga craters ang'onoang'ono padziko ndi unsightly.The chifukwa chachikulu pini holing zikuwoneka kuti discrete poliyesitala utomoni particles kukhudzana ndi kanasonkhezereka zitsulo pamwamba musati fuse pa nthawi yomweyo monga pamwamba pa poliyesitala ufa. filimu, chifukwa cha unyinji wa kanasonkhezereka zitsulo , ndi nthawi yotengedwa kuti abwere kutentha maphatikizidwe.
• Ma resin opangidwa mwapadera okhala ndi 'degassing' agents apangidwa kuti athetse vutoli mwa kuchedwetsa kuyambika kwa kuphatikizika kwa ufa. Pre-Kutenthetsa ntchito mu chisanadze kutentha uvuni pamaso pa ufa ntchito amalola cholemera otentha kuviika kanasonkhezereka zigawo kuti ufa TACHIMATA ndi kuthana ndi vuto la pini holing pamene ntchito molumikizana ndi 'degassing' kalasi ya poliyesitala ufa ❖ kuyanika.
