Kodi tingawonjezere bwanji kugwira ntchito kwa mafupa a fumbi?

Monga mafupa a thumba la fumbi lotolera, kufunikira kwa khalidwe lake kumawonekera.Ndiye tingalimbikitse bwanji kugwira ntchito kwa mafupa a fumbi?Kupopera mbewu mankhwalawa kwa mafupa ochotsa fumbi ndi njira yabwino yotetezera, yomwe ingakhale yabwinoko kuposa mafupa ochotsa fumbi.

1, kanasonkhezereka fumbi kuchotsa mafupa n'zosavuta kukhudzidwa ndi zinthu zachilengedwe ndi dzimbiri, amene amachepetsa mwachindunji moyo wa thumba fumbi wotolera ndi fumbi thumba.

2, mafupa a fumbi pambuyo posindikiza zomatira ndi mphamvu zamakina zidzawonjezeka.

3. Pambuyo kupopera mbewu mankhwalawa, fumbi kuchotsa mafupa akhoza kupirira lipoti lenileni.

4, chifukwa kupopera mbewu mankhwalawa, pamwamba ndi yosalala, yabwino unsembe.

Mfundo ya kupopera mbewu mankhwalawa mafupa a fumbi: kugwiritsa ntchito corona discharge phenomenon powder coating adsorption pa workpiece.Njirayi ndi: ufa wa ufa ndi dongosolo ndi mpweya mu wothinikizidwa mpweya kutsitsi mfuti, kutsogolo mfuti ndi mkulu voteji electrostatic jenereta wa kuthamanga kwambiri, chifukwa cha kukhetsa corona, pafupi malipiro ake tima, ufa ndi mfuti nozzle ndege, mapangidwe wa ❖ kuyanika particles mlandu, ndi udindo wa electrostatic mphamvu, anayamwa mu polar chosiyana workpiece, ndi kuwonjezeka kwa chiwerengero cha ufa kutsitsi, ndi zambiri mlandu kudzikundikira, Pamene makulidwe anatsimikiza, chifukwa electrostatic repulsion. , izo sizidzapitiriza adsorb, kotero kuti workpiece lonse kupeza makulidwe ena a ❖ kuyanika ufa, ndiyeno pambuyo kutentha kwambiri kuti ufa kusungunuka, kusanja, kuchiritsa, ndiko kuti, kupanga filimu yolimba pamwamba. wa workpiece.

M'malo mwake, kutsitsi kochotsa fumbi kumangoyang'anitsitsa kuchotsa mafuta koyambirira, kuchotsa dzimbiri ndi phosphating.Ufa wa polyester uyenera kugwiritsidwa ntchito popopera mbewu mankhwalawa, ndipo kutentha kuyenera kuyendetsedwa pakati pa 180 ndi 260 digiri Celsius.
