Cathodic ED Irangi Epoxy Electrophoretic Coating
Amahame shingiro nuburyo bukoreshwa
Cathodic epoxy electrophoretic coating.
Ibisubizo by'ingenzi:
Electrolysis: Kugabanya amazi kuri cathode bitanga OH-ion.
Amashanyarazi:Epoxy-amine yuzuye neza yimuka yerekeza kuri cathode.
Amashanyarazi: Ibice byegeranye kuri substrate, bikora firime ikingira.
Electroosmose: Amazi arasohoka, byongera gukomera.
Ibice byingenzi
Ibigize | Imikorere | Ibikoresho bisanzwe |
Epoxyamine resin | Tanga skeleton yubatswe hamwe nuburyo bwiza | Epoxy resin + guhindura diethylamine |
| Umukozi uhuza
| Ifite imiyoboro itatu-yimiterere mugihe cy'ubushyuhe bwo hejuru | Ubwoko bwa isocyanates bufunze (urugero, TDI-caprolactam ifunze ibice) |
Kutabogama | Guha resin hamwe no gukwirakwiza amazi | Acide isanzwe, aside aside |
Inyongera | Kunoza imikorere (kubungabunga, kuringaniza, guhanagura) | PTFE, umukozi uhuza silane, boron nitride (BN) |
Inzira
Mbere yo kuvurwa: Gutesha agaciro → gukaraba → guhinduranya ubuso → fosifate (gukora fosifate kugirango wongere imbaraga).
Ikigega cya Electrophoresis: Ibipimo: voltage 150–400V | igihe 2–4min | ubushyuhe 28-32 ° C | ibintu bikomeye 18-20%.
Nyuma yo koza: Ultrafiltration (UF) sisitemu yo gusubiramo igarura irangi ireremba, hamwe nigipimo cyo gukira> 99%.
Guteka no gukiza: 160–180 ° C × 20-30min (ikuraho umukozi uhuza, arangiza gukira)
Kugereranya Ubwoko bwa Coating
Umutungo | Anodic E-ikoti | Cathodic Epoxy E-ikoti |
Kurwanya ruswa | Guciriritse | Nibyiza (1.000+ hr spray yumunyu) |
Gucika Ibyuma | Birashoboka (okiside ya anode) | Nta na kimwe (kurinda catodiki) |
Igipfukisho | Guciriritse | Ikirenga |
Ingaruka ku bidukikije | VOC yo hasi | Ultra-hasi VOC (ishingiye ku mazi) |
Ibisanzwe | Ibyuma byo mu nzu | Imodoka, marine, imiyoboro |
Ahantu ho gusaba
Gukora ibinyabiziga: Umubiri wumubiri, ibiziga, chassis (bingana na 70% byisoko rya e-coat kwisi).
Ubwubatsi bw'ingufu:Imiyoboro ya peteroli / gazi, iminara ya turbine yumuyaga (ihujwe na sisitemu yo gukingira catodiki).
Ibyuma bya elegitoroniki n'ibikoresho:Inzu ya moteri, imirasire (irwanya voltage irwanya > 5 kV / mm).
Imirima ivuka: Kubika ingufu za hydrogène nibikoresho byo gutwara, litiro-ion ya batiri (kurinda ruswa + kwishyira hamwe).
Ibyiza byo gukora
Kurinda ruswa: Iyo ikoreshejwe ifatanije na sisitemu yo gukingira cathodic, irashobora kwongerera igihe cyimirimo yimiyoboro mubutaka / ibidukikije.
Ubwishingizi bumwe:Kugera ku burebure buhoraho (15-30microns) kuri geometrike igoye (nk'amakadiri y'imodoka).
Umutekano w’ibidukikije:Amazi ashingiye kumazi agabanya imyuka ihindagurika y’ibinyabuzima (VOC) hejuru ya 90% ugereranije n’ibishishwa bishingiye ku musemburo.
