Benshi mubatangiye kugwa mumutego mugihe baguze ibara ryuzuye ibara kuko batumva ibikoresho byabo. None, ni ibihe bikoresho nibyiza kumuzingo wuzuye amabara?
Substrate yamabara yatwikiriye ibara irashobora kuba ibicu bikonje cyangwa ibyuma bishyushye bikoresha amashanyarazi. Nubwo gutwika kama yibikoresho byamabara bifite ibara ryiza bifite ingaruka nziza zo kurwanya ruswa, haracyariho icyuho gito mumyanda kama, gishobora gutuma umwuka nubushuhe byinjira kandi bigatera ingese ya substrate. Kubwibyo, ibara risize amabara rikozwe mubutaka budafunze rifite ubuzima bwigihe gito kandi bikunda gukwirakwizwa no gukuramo ibishishwa nyuma yo gushushanya. Substrate yamabara yatwikiriwe nicyuma cyane cyane icyuma cyometseho icyuma cyangwa icyuma gisya ibyuma bya tekinoroji. Mu mirongo imwe n'imwe yo kubyaza umusaruro, uburyo bwo gukora ibara ryamabara bigabanijwemo mbere yo kuvura substrate mbere yo kuvura, imiti ihindura imiti (itari iy'icyuma kama), ibinyabuzima bitari ubutare, hamwe nuburyo bwo gutwikira.

1 、 Substrate pre-treatment: Niba tutari isosiyete ishobora kwinjira muburyo butaziguye bwo gusiga amabara ya societe nyuma yumusaruro, isahani yicyuma ikoreshwa nka substrate irashobora guhora ihura ningese (ingese yera), ivumbi, nibindi byanduye mugihe cyo gutwara no kwiteza imbere. . Niba ibi bidashobora kuvaho, ubwiza bwirangi buzagira ingaruka. Ubwiza bwibara ryuzuye ryuzuye hamwe nibikorwa bya tekinike na chimique byabanyeshuri bose bifitanye isano rya bugufi mbere yo kuvurwa. Byongeye kandi, mugutezimbere umusaruro, murwego rwo gukumira ingese n’amavuta, ayo mavuta nayo akurwaho mbere yo gutanga amabara. Uburyo bukoreshwa mbere yo kuvura ubu nuburyo bwa alkaline igisubizo cyo gutesha agaciro.
2 film Filime ihindura imiti ifite imirimo ibiri
Imwe muriyo ni ugutezimbere ubushobozi bwo kwirinda ingese,
Iya kabiri ni ukunoza guhuza hagati ya substrate no gutwikira, no kunoza imikorere ya substrate.

Muri rusange hari intambwe eshatu:
Imwe muriyo ni fosifate, ibanza gukora kristu nyinshi hejuru yicyuma, hanyuma igakora urwego rwa firime ya fosifate hejuru yicyuma hamwe numuti wumunyu wa fosifate;
Iya kabiri ni passivation no gushiraho ikimenyetso. Filime ya fosifate iracyafite imyenge imwe nimwe, ikoreshwa muburyo bwa chimate hamwe na chromate kugirango ikore firime ikingira. Icya gatatu, oza n'amazi meza hanyuma ukureho igisubizo cya passivation ukoresheje amazi yanduye cyangwa yanduye.
3 ats Ibifuniko kama bigabanijwemo primer na topcoat. Ibisabwa byibanze ntabwo biri hejuru kandi birashobora gukoreshwa muburyo bworoshye. Ariko, murwego rwo kunoza umutekano wamakuru yumusaruro, inganda zUbushinwa muri rusange zikoresha uburyo bwo guhinduranya ibara ryerekana primer na topcoat.
Igikorwa cyo gutwikisha inyandiko: Igikorwa cyo gutwikisha iposita kirimo gucapa, gushushanya, firime irinda ibishishwa, guhuza, nibindi, bitezimbere imitako irinda kandi ikingira ikibaho.
