Ni gute icyuma cya galvanised "gihinduka" kikavamo ibara - PPGI Coil?

Mu nzego nyinshi nko mu bwubatsi no mu bikoresho byo mu rugo, PPGI Steel Coils zikoreshwa cyane bitewe n'amabara meza yazo n'imikorere myiza cyane. Ariko se wari uzi ko "iyabanjirije" ari Galvanized Steel Coil? Ibi bikurikira bizagaragaza uburyo Galvanized Sheet Coil ikorwamo PPGI Coil.

1. Gusobanukirwa imiyoboro ya Galvanized na PPGI Coils

Abakora Galvanized Coils basiga urwego rwa zinc ku buso bwazo, ahanini rukora akazi ko kwirinda ingese kandi rukongera igihe cy'imikorere y'icyuma. Galvanized coils za PPGI zifata Galvanized coils nk'umuyoboro w'icyuma. Nyuma yo gutunganya inshuro nyinshi, hashyirwamo organic coatings ku buso bwazo. Ntabwo gusa bigumana ingese nk'ibyuma bya Galvanized coils ahubwo binatanga imiterere myiza nko kuba ubwiza no kwihanganira ikirere.

 

2. Intambwe z'ingenzi zo gukora uruganda rw'ibyuma bya galvanised

(1) Uburyo bwo kuvura mbere yo kuvura - Gukuraho amavuta: Ubuso bw'ibyuma bya galvanised bushobora kuba bufite imyanda nka peteroli n'umukungugu. Iyi myanda ikurwaho hakoreshejwe imiti ya alkaline cyangwa imiti ikuraho amavuta kugira ngo habeho guhuza neza irangi rikurikiraho n'ubutaka. Urugero, gukoresha umuti ukuraho amavuta urimo surfactant bishobora kubora neza molekile z'amavuta.

Uburyo bwo Guhindura Ingufu: Ubusanzwe burimo uburyo bwo gutunganya chromium cyangwa chromium-free passivation. Bukora icyuma gito cyane cya chemical ku buso bw'icyuma gikozwe muri galvanised, kigamije kongera uburyo bwo gufatana hagati y'ubutaka n'irangi mu gihe burushaho kunoza uburyo bwo kurwanya ingese. Iyi filime imeze nk' "ikiraro", ituma irangi rihuzwa neza n'icyuma gikozwe muri galvanised.

(2) Uburyo bwo gusiga amarangi - Gusiga primer: Primer ishyirwa ku cyuma cya galvanized coil cyavuwe mbere hakoreshejwe irangi rya roller coating cyangwa ubundi buryo. Akamaro k'ingenzi k'icuma ni ukwirinda ingese. Gifite ibara rirwanya ingese na resins, bishobora gukuramo neza uburyo amazi, ogisijeni n'urukuta rwa galvanized bihurirana. Urugero, primer ya epoxy ifite ubushobozi bwo gufata neza ingese kandi irwanya ingese.

Gusiga Topcoat: Hitamo irangi ry'amabara atandukanye n'imikorere yo gusiga bitewe n'ibisabwa. Topcoat ntituma gusa PPGI coil ibona amabara meza, ahubwo inatanga uburinzi nko kwirinda ikirere no kudashira. Urugero, polyester topcoat ifite amabara meza kandi irwanya UV, bigatuma ikoreshwa mu bwubatsi bwo hanze. Hari irangi ry'amabara menshi rifite n'irangi ry'inyuma kugira ngo ririnde inyuma y'ubutaka kwangirika kw'ibidukikije.

(3) Guteka no Gutunganya Icupa ry'icyuma gishushanyijeho irangi ryinjira mu itanura ritetseho ubushyuhe runaka (ubusanzwe 180℃ - 250℃). Ubushyuhe bwinshi butuma resin iri mu irangi inyura mu buryo buhuza, igakomera ikaba agapfukamunwa gakomeye. Igihe cyo guteka n'ubushyuhe bigomba kugenzurwa neza. Iyo ubushyuhe buri hasi cyane cyangwa igihe kitari gihagije, agapfukamunwa k'irangi ntikizakira burundu, bigira ingaruka ku mikorere; niba ubushyuhe buri hejuru cyane cyangwa igihe kirekire cyane, agapfukamunwa k'irangi gashobora guhinduka umuhondo kandi imikorere yako ishobora kugabanuka.

(4) Nyuma yo gutunganya (Ntabwo ari ngombwa) Hari ibyuma bya PPGI byuma bitunganywa nyuma yo gutunganya nko gushushanya, gusiga amavuta, nibindi nyuma yo kuva mu itanura. Gusiga amavuta bishobora kongera ubwiza bw'ubuso n'ubushyuhe, kandi gusiga amavuta bishobora kurinda ubuso bwo gusiga mu gihe cyo gutwara no gutunganya kugira ngo hirindwe gushwanyagurika.

 

3. Ibyiza n'Imikoreshereze ya PPGI Steel Coils Binyuze muri ubu buryo bwavuzwe haruguru, galvanized steel coil "yahinduwe" neza ikaba PPGI coil. PPGI Coil ni nziza kandi ikora neza. Mu rwego rw'ubwubatsi, zishobora gukoreshwa ku nkuta zo hanze n'ibisenge by'inganda. Zifite amabara atandukanye, ziraramba kandi ntizishira. Mu rwego rw'ibikoresho byo mu rugo, nka firigo n'ibikoresho bikonjesha, byombi biraryoshye kandi biranga ubwiza bwabyo. Imikorere yabyo myiza cyane ituma bifata umwanya ukomeye mu nganda nyinshi. Kuva kuri galvanized coil kugeza kuri PPGI coil, impinduka isa n'iyoroshye mu by'ukuri ikubiyemo ikoranabuhanga rihamye n'uburyo bwa siyansi. Buri sano ry'umusaruro ni ingenzi, kandi byose hamwe birema imikorere myiza ya PPGI coil, byongera ibara n'uburyohe mu nganda zigezweho n'ubuzima.
