PPGI ni iki?

PPGIbyashushanyijwe mberebyashyizwemo amashanyarazi icyuma, izwi kandi nka icyuma cyashyizwemo kera, icyuma gitwikiriwe n'imigozi, icyuma gitwikiriwe n'amabara n'ibindi, akenshi gifite substrate y'icyuma gitwikiriwe n'imigozi ishyushye.

Iri jambo ni inyongera ya GI ari na ryo jambo risanzwe rikoreshwa mu gusobanura icyuma cya galvanized iron. Muri iki gihe ijambo GI rikunze kuvuga icyuma cya zinc (>99%) gishyushye cyane, bitandukanye no gukoresha uburyo bwo gusimbuza. PPGI ivuga icyuma cyasizweho zinc gikozwe mu ruganda, aho icyuma gisigwa irangi mbere yo gusimbuza, aho gusimbuza irangi nyuma yo gusimbuza irangi bibaho nyuma yo gusimbuza irangi.

Uburyo bwo gusiga irangi ry'icyuma gishyushye bukoreshwa kandi mu gukora urupapuro rw'icyuma n'urusobe rw'irangi rya aluminiyumu, cyangwa irangi rya aluminiyumu rya zinc/aluminium, zinc/icyuma na zinc/aluminium/magnesium bishobora no gusigwa irangi mu ruganda. Nubwo rimwe na rimwe GI ishobora gukoreshwa nk'ijambo rusange ku byuma bitandukanye bishyushye bisiga irangi ry'icyuma, ahubwo yerekeza gusa ku byuma bisiga irangi rya zinc. Mu buryo nk'ubwo, PPGI rimwe na rimwe ishobora gukoreshwa nk'ijambo rusange ku byuma bitandukanye bisiga irangi byasizwe irangi, ariko akenshi yerekeza ku byuma bisiga irangi byasizwe irangi rya zinc.

Ubusanzwe, icyuma gitwikiriwe na zinki cya PPGI gikorerwa ku murongo ukomeza gukaraba (CGL). CGL ishobora kuba irimo igice cyo gusiga amarangi nyuma y’igice gishyushye cyo gukaraba, cyangwa akenshi icyuma gitwikiriwe na zinki mu buryo bwa coil gitunganywa ku murongo utandukanye w’irangi rikomeza gukaraba (CPL). Icyuma gitwikiriwe na zinki gisukurwa, kigatunganywa mbere, kigashyirwamo ibice bitandukanye by’imyambaro y’umwimerere ishobora gukaraba.amarangi,vinylgukwirakwira, cyangwaamatafari ya laminateUburyo buhoraho bukoreshwa mu gushyiramo izi mpako bukunze kwitwa Coil Coating.

Ibyuma bikorwa muri ubu buryo ni ibyasizwe irangi, byarangiye kandi byiteguye gutunganywa mu bikoresho cyangwa ibice byarangiye gukoreshwa.

Uburyo bwo gusiga coil bushobora gukoreshwa ku zindi substrates nka aluminiyumu, cyangwa aluminiyumu, icyuma kitagira umugese cyangwa icyuma gitwikiriwe na alloy kitari icyuma "cyuzuye" gitwikiriwe na zinc. Ariko, icyuma "cyuzuye" gitwikiriwe na zinc gusa ni cyo kizwi nka PPGI. Urugero, PPGL ishobora gukoreshwa ku cyuma cya 55% Al/Zn gitwikiriwe na alloy (icyuma cya GALVALUME gitwikiriwe na alloy) cyashyizwemo irangi.

Ibikoresho by'icyuma byakozwe mbere bya galvanized (PPGI)
