Ubunini bwa coating nicyo kintu cyingenzi cyingwate yo kurwanya ruswa.Ninini yubunini bwa coating, nibyiza birwanya ruswa, byagaragaye ko byihuta cyane nibizamini byizuru.
Nkuko bigaragara hano hepfo:
Kubisahani byamabara ashingiye kuri (aluminium) zinc plaque, uburebure bwa coating bugira ingaruka cyane cyane kumikorere yibyuma byamabara.Kunanura substrate, kubyimbye bya zinc, no kurwanya ruswa yo gukata.Kugeza ubu bizwi ku rwego mpuzamahanga ko igipimo cya zinc ≥ 100 ari uburinzi bukomeye bwo kwirinda kwangirika kw’ibara risize amabara.
Icyemezo.Ufashe 0.5mm substrate nkurugero, ibisahani kuri metero kare kuruhande rumwe bigomba kugera byibuze 50g.
Nigute ushobora guhitamo ubwoko bwa coating
Uruhare rwibanze rwigitereko rugaragarira mubikorwa byombi bigaragara no mubikorwa byo kurinda.Ibara ryikibiriti rishobora kugabanywamo ibice kama nimbuto zidasanzwe, hamwe namabara meza kandi meza;Ibinyabuzima bidafite umubiri mubusanzwe bifite ibara ryoroshye, ariko imiterere yimiti hamwe no kurwanya UV biruta pigment organic.
Ikoti ikoreshwa cyane kumasahani yamabara arimo polyester (PE), silicon yahinduwe polyester (SMP), polyester iramba cyane (HDP), na fluoride polyvinylidene (PVDF).Buri koti ikwiranye nibihe bitandukanye, kandi turasaba gukoresha ibicuruzwa bya HDP cyangwa PVDF mugihe ubukungu bubyemereye.
Kugirango uhitemo primer, epoxy resin igomba gutoranywa niba gutsindagira hamwe no kurwanya ruswa;Kugirango urusheho kwitondera guhinduka no kurwanya UV, hitamo polyurethane primer.
Kubitwikiriye inyuma, niba ibara ryometseho ibyuma bikoreshwa nkisahani imwe, hitamo ibice bibiri, ni ukuvuga igice kimwe cyinyuma primer nigice kimwe cyinyuma cyanyuma.Niba ibara ryometseho ibyuma bikoreshwa nkibisahani cyangwa sandwich, hashyizweho urwego rwa epoxy resin.
Ingaruka zo gutwikira umubyimba mubuzima bwa serivisi
Icyuma gisize amabara gishobora kugira uruhare runini mukurinda ruswa, ukoresheje firime yo gutwikira ibintu byangirika.Ariko, kubera isura ya microscopique ya firime yikingira ubwayo, haracyariho imyenge, kandi umwuka wamazi muke mukirere uzakomeza gutera hejuru, bigatera ibisebe kandi birashoboka ko firime yatwikiriye.Isahani yicyuma, isahani
Igice (zinc plaque cyangwa aluminium zinc plaque) gifite ingaruka zikomeye kubuzima bwicyuma.
Kubwuburinganire bumwe, igifuniko cya kabiri ni cyinshi kuruta igifuniko cyibanze, hamwe no kurwanya ruswa hamwe nigihe kirekire cyo gukora.Kubyibushye, dushingiye kubisubizo byikizamini cya ruswa, turasaba ko igipande cyimbere cyaba 20 um cyangwa kirenga, kuko uburebure bwa firime buhagije bushobora gukumira ruswa mugihe cyemewe.
Irinde ko habaho ruswa (PVDF isaba umubyimba mwinshi bitewe nubuzima bwa serivisi ndende, mubisanzwe 25 μ M cyangwa irenga).
