Prepreatment ndi electrocoating process

Kufotokozera Kwachidule:

Kupaka pretreatment ndiko kukonzekera kwa nsabwe za m'madzi musanaphike ndipo ndiye maziko a ndondomeko yonse yophimba.
Ubwino wa pretreatment mwachindunji zimakhudza lonse ❖ kuyanika khalidwe, kotero tiyenera kulabadira izo.

Zida zosiyanasiyana ndi mankhwala awo pokonza, zoyendetsa, zosungirako, pamwamba pake zimakhala zosavuta kupanga kapena
kumamatira zinthu zakunja, monga machining burr, khungu la oxide, mafuta, ndi zina zotero, zonyansa zapamtundazi zidzakhudza kuphatikizika kwa zokutira ndi mphamvu yomangirira ndi matrix. Kupaka koyambirira kwa chinthu chachikulu Cholinga ndikuchotsa zinthuzi ndikuchita kutembenuka koyenera kwa mankhwala kuti apereke zoyenera Kupaka kwa gawo lapansi, kuti awonjezere kumamatira kwa filimuyo, kutalikitsa moyo wautumiki wa filimuyo, Perekani kusewera kwathunthu kwa zoteteza. zotsatira ndi kukongoletsa zotsatira ❖ kuyanika.

Choncho, utsi zili pamaso processing. Zimaphatikizapo mbali zotsatirazi:

Degreasing pamaso ❖ kuyanika

Chitsulo ndi mbali zake mu ndondomeko yosungirako ndi zoyendera ntchito odana rust chitetezo mafuta, pepala zitsulo workpiece mu kujambula mafuta ayenera kugwiritsidwa ntchito pamene kuthamanga processing, mbali ayenera kukhudzana emulsion pamene Machining, kutentha mankhwala angagwirizane kuzirala mafuta, pamene mbali zambiri mafuta. Madontho ndi HanJi a manja a woyendetsa, mafuta a ziwalozo komanso zonyansa monga nthawi zonse ndi fumbi losakanikirana Zonsezi, mitundu yonse ya mafuta pazigawo zomwe sizimalepheretsa kupanga filimu ya phosphating, komanso zimakhudza kumamatira kwa kuyanika kuyanika ntchito yokongoletsa ndi kukana dzimbiri Gulu 3-1 limatchula kasamalidwe kosiyana ka mbale zoziziritsa zitsulo. Zotsatira za zokutira za cathodic electrophoretic pakukana kwa dzimbiri.

Phosphating

Phosphating ndi njira yosavuta, yodalirika, yotsika mtengo komanso yosavuta kuti ipititse patsogolo kwambiri kukana kwa dzimbiri kwa zokutira zachitsulo. Amagwiritsidwa ntchito kwambiri kunyumba ndi kunja, makamaka popaka magalimoto, omwe amagwiritsidwa ntchito kwambiri m'zaka zaposachedwa. Pafupifupi 100% ya mbali woonda mbale mbale mu makampani galimoto ndi phosphating Phosphating ndondomeko amatanthauza zitsulo pamwamba kukhudzana ndi njira asidi munali dihydrogen mankwala mchere, mankhwala anachita ndi kwaiye mu zitsulo pamwamba bata la insoluble pawiri pawiri nembanemba wosanjikiza. pamwamba mankhwala mankhwala njira ndi kwaiye filimu wotchedwa phosphating filimu.

Phosphate filimu mfundo

filimu ya phosphating inatha kupereka maziko oyenera kwambiri opaka utoto, chifukwa cha zotsatirazi:
1) Amapereka malo oyera, yunifolomu, opanda mafuta pamaziko a degreasing kwathunthu
2) kumawonjezera kumamatira a organic filimu ku gawo lapansi chifukwa cha thupi ndi mankhwala kanthu N'kovuta kumvetsa kuti porous dongosolo phosphating filimu kumawonjezera pamwamba pa gawo lapansi, kotero kuti kugwirizana chigawo pakati pa awiri ukuwonjezeka molingana, ndi kupindula kopindulitsa pakati pa zigawo ziwiri za filimu kumapangidwa. Nthawi yomweyo, kuyanjana kwamankhwala pakati pa unsaturated resin ndi phosphate crystal kumapangitsanso mphamvu yake yomanga.
3) kupereka khola sanali conductive kudzipatula wosanjikiza, kamodzi ❖ kuyanika kuwonongeka, ali ndi udindo wa dzimbiri chopinga, makamaka kwa anode incision Mfundo yoyamba nthawi zambiri kunyalanyazidwa Only kuti kwathunthu kwa mafuta abwino kwambiri kupanga phosphating wokhutiritsa filimu Choncho. filimu ya phosphating yokha ndiyomwe imakhala yodziwika bwino kwambiri yaukadaulo wa pretreatment wodalirika wodzifufuza.
