Imbere yinzoga zibiri n'ibinyobwa

Ibinyobwa byiza 7-19 byiza (1)
Inzoga n'ibinyobwa birashobora kuba uburyo bwo gupakira ibiryo, kandi ntibigomba kongera cyane kubiciro byibirimo. Ababikora barashobora guhora bashaka uburyo bwo gukora paki ihendutse. Isafuriya imaze gukorwa mu bice bitatu: umubiri (uhereye ku rupapuro ruringaniye) n'impera ebyiri. Ubu ibyombo byinshi byinzoga nibinyobwa nibice bibiri. Umubiri ukorwa mubice bimwe byicyuma muburyo buzwi nko gushushanya no gukata urukuta.

Ubu buryo bwo kubaka butuma ibyuma byoroheje bikoreshwa kandi isafuriya ifite imbaraga ntarengwa gusa iyo yuzuyemo ibinyobwa bya karubone kandi bifunze. Kuzunguruka izigama icyuma mugabanya diameter yijosi. Hagati ya 1970 na 1990, inzoga n'ibinyobwa byoroheje 25%. Muri Amerika, aho aluminiyumu ihendutse, inzoga n'ibinyobwa byinshi bikozwe muri icyo cyuma. Mu Burayi, amabati akenshi ahendutse, kandi amabati menshi akozwe muribi. Inzoga zigezweho n'ibinyobwa tinplate ifite amabati make hejuru, imirimo nyamukuru y amabati ni kwisiga no gusiga (muburyo bwo gushushanya). Birakenewe rero lacquer ifite ibintu byiza birinda umutekano, kugirango ikoreshwe byibuze uburemere bwikoti (6-12 µm, biterwa nubwoko bwicyuma).

Gukora ibishoboka nubukungu gusa iyo amabati ashobora gukorwa vuba cyane. Amabati agera kuri 800-1000 kumunota azakorwa kumurongo umwe utwikiriye, hamwe numubiri hamwe nimpera bitwikiriye ukundi. Imibiri yinzoga n'ibinyobwa irashishwa nyuma yo gukorwa no guteshwa agaciro. Porogaramu yihuse igerwaho nigisasu kigufi cya spray idafite umuyaga uva kumurongo uhagaze ahateganye rwagati rwagati rwanyuma rwa horizontal. Amacumu arashobora kuba ahamye cyangwa arashobora kwinjizwa mumasafuriya hanyuma agakurwaho. Isafuriya ifashwe mukantu hanyuma ikazunguruka vuba mugihe cyo gutera kugirango ubone igifuniko kimwe gishoboka. Gufunga ibishishwa bigomba kuba bike cyane, kandi bigakomera hafi 25-30%. Imiterere iroroshye, ariko imbere hakira umuyaga ushushe, muri gahunda nka 3 min kuri 200 ° C.

Ibinyobwa bidasembuye bya karubone ni acide. Kurwanya ruswa kubicuruzwa nkibi bitangwa na coatings nka epoxy-amino resin cyangwa sisitemu ya epoxy-fenolike. Inzoga ni ibintu bituzuye byuzuye kuri kanseri, ariko uburyohe bwayo burashobora kwangirika byoroshye mugutoragura ibyuma bivuye mumasafuriya cyangwa nibikoresho byakuwe muri lacquer, kuburyo bisaba na lacquer zo mu rwego rwo hejuru.

Ibyinshi muri ibyo bipfundikizo byahinduwe neza mumazi ya colloidally yatatanye cyangwa sisitemu ya polymer ya emulsiya, cyane cyane kuri substrate yoroshye kurinda, aluminium. Amazi ashingiye kumazi yagabanije ibiciro muri rusange kandi agabanya urugero rwumuti ugomba gutabwa na nyuma yo gutwika kugirango wirinde umwanda. Sisitemu nyinshi zatsinze zishingiye kuri epoxy-acrylic copolymers hamwe na amino cyangwa fenolike ihuza.

Haracyariho inyungu zubucuruzi muri electrodeposition ya lacquers zishingiye kumazi mubinyobwa n'ibinyobwa. Ubwo buryo bwirinda gukenera gukoreshwa mu makoti abiri, kandi birashoboka ko bushobora gutanga impuzu zitagira inenge zirwanya ibiri muri kanseri ku buremere bwa firime yumye. Mu mavuta aterwa n'amazi, harashakishwa ibintu biri munsi ya 10-15%.
