Kwitegura E-ikoti Sisitemu yo gushushanya E-gutwikira umurongo

Cathodic epoxy electro-coatingni igipimo cyo kurwanya ruswa. Ikoreshwa cyane mu nganda zikoresha ibinyabiziga n’ibinyabiziga, zitanga spray yumunyu mwinshi, ubushuhe hamwe nindwara irwanya ruswa. Nyamara, tekinoroji ya cathodic epoxy muri rusange isaba ikoti yo hejuru kurinda izuba. Ubwoko bwa Aromatic epoxy-coating ikunze kwibasirwa no kwangirika hamwe na UV yibice byizuba.

Cathodic acrylic electro-coatingiraboneka muburyo butandukanye bwurumuri namabara kugirango bigaragare neza igihe kirekire, kugumana ububengerane, kugumana amabara no kurinda ruswa. Ibicuruzwa bikoreshwa nk'umwenda umwe urangirira mu buhinzi, ibyatsi n'ubusitani, ibikoresho, n'inganda zikonjesha.

Cathodic acrylic electrocoatings ikoreshwa mubisanzwe aho byifuzwa igihe kirekire cya UV no kurinda ruswa kuri ferrous substrate (ibyuma). Cathodic acrylics nayo ikoreshwa mubisabwa aho hifuzwa amabara yoroheje.

Inzira ya electrocoat irashobora kugabanywamo ibice bine bitandukanye:

• Kwitegura

Ikigega cya E-coat hamwe nibikoresho bifasha

• Kohereza

• Gukiza ifuru

Muburyo busanzwe bwa e-coat, ibice byabanje gusukurwa no kubanza gukoreshwa hamwe na fosifate ihinduranya kugirango itegure igice cyamashanyarazi. Ibice noneho byinjizwa mubwogero bwo gusiga irangi aho amashanyarazi akoreshwa hagati yibice na electrode ya “compteur”. Irangi rikururwa n'umuriro w'amashanyarazi igice kandi ugashyirwa kuruhande. Ibice bivanwa mu bwogero, byogejwe kugirango bigarure ibishishwa bidasize irangi, hanyuma bitekwa kugirango bikize irangi.

Mbere yo gusiga amarangi ya firime, hejuru yicyuma cyakira kwitegura bisanzwe birimo gutwikira.

Uburyo busanzwe bwo kwitegura kuri e-coat bugizwe nintambwe zikurikira:

1) Isuku (icyiciro kimwe cyangwa byinshi)

2) Kwoza

3) Imiterere

4) Ipitingi

5) Kwoza

6) Nyuma yo kuvurwa

7) Kwoza amazi ya Deionised.

Inzira ya fosifati irashobora gutandukanywa muburyo bubiri: fosifate yicyuma na fosifike ya zinc. Icyuma cya fosifate cyabaye inzira yo guhitamo kubisabwa aho muri rusange gutekereza kubiciro birenze imikorere ikenewe. Kubera ko fosifate yicyuma ari ntoya kurusha fosifike ya zinc kandi ikubiyemo gusa ion yicyuma cya substrate itunganywa, itanga imbaraga zo kurwanya ruswa ugereranije na sisitemu ya fosifike. Nubwo, ibidukikije bibangamira ibidukikije bigenda byiyongera kubijyanye n’ibyuma biremereye, icyuma cya fosifate yicyuma hamwe nubuvuzi bunoze bushobora gutanga ubundi buryo bushoboka mugihe hakiri ibisabwa ibisobanuro bya ruswa. Fosifike ya Zinc yahindutse uburyo bwo kuvura mbere yo gutunganya inganda zangiza ibyuma, cyane cyane hakoreshejwe uburyo bwo gusiga amarangi ya electrocoat. Impamvu nuko batanga uburyo bwiza bwo kurwanya ruswa no gufatira irangi kuruta fosifati yicyuma mugihe gikenewe cyane.
