Byoherejwe 2018-11-12Ipitingi ya Dacromet, izwi kandi nka zinc flake coating, ifite akarusho ko iyanyuma idashobora kugerwaho ugereranije nubuhanga busanzwe bwa electro galvanised na hot dip galvanizing.Zinc flake coating ifite ibyiza bikurikira:
# 1.Kurwanya ruswa idasanzwe
Kurinda amashanyarazi agenzurwa na zinc, ingaruka zo gukingira amabati ya zinc / aluminiyumu hamwe ningaruka zo kwikosora ya chromate ituma igifuniko cya Dacromet cyihanganira cyane kwangirika mugihe igipfunyika cya Dacromet gipimishijwe mumiti itabogamye.Bifata amasaha agera kuri 100 kugirango ushireho umwenda 1um, uruta inshuro 7-10 kuruta kuvura gakondo.Ikizamini cyumunyu utagira aho kibogamiye kirashobora kumara amasaha arenga 1000 (gutwikira hamwe nubunini bwa 8um cyangwa arenga), ndetse bimwe ndetse birenze, ibi ntibishoboka hamwe na galvanise kandi ishyushye cyane.
# 2.Kurwanya ubushyuhe buhebuje
Kubera ko polimeri ya Dakoro yubatswe na chromic aside idafite amazi ya kirisiti kandi aho gushonga k'urupapuro rwa aluminium / zinc ni ndende, igifuniko gifite imbaraga zo kurwanya ubushyuhe bwo hejuru cyane.Ipitingi ya Dacromet ifite ubushyuhe bwo kurwanya ubushyuhe bwa 300 ° C. Irashobora gukoreshwa ubudahwema igihe kirekire kuri 250 ° C. Kurwanya ruswa kwayo ntaho ihuriye, kandi firime ya passivation hejuru yubushyuhe bwa zinc yangiritse hafi. 70 ° C, kandi kurwanya ruswa ni kugabanuka gukabije.
# 3.Nta hydrogene yubusa
Mugihe cyo kuvura tekiniki ya Dacromet, nta gukaraba aside, electrodeposition, de-amavuta, nibindi, kandi nta reaction ya electrochemic reaction ya hydrogène yatewe na electro-galvanizing, bityo ibikoresho ntibizatera hydrogene.Birakwiriye rero cyane cyane gukora ibice bya elastike hamwe nimbaraga zikomeye zakazi.
# 4.Kubangikanya
Isura ya Dacromet itwikiriye ni ifeza-imvi hamwe no gufatana neza na substrate hamwe nuburyo butandukanye.Irashobora gukoreshwa nkigice cyo hejuru cyangwa nka primer kubintu bitandukanye.Amashanyarazi yibintu bibaho hagati yicyuma bitewe nibishobora gutandukana.Kubice bya galvanised, byombi bishingiye ku byuma na aluminiyumu birwanya amashanyarazi kandi bigabanya cyane kurwanya ruswa.Kuri Dacromet anti-ruswa, kubera ko anti-ruswa ishingiye kuri passivasi ya chromic acide hamwe no kurinda ibitambo bigenzurwa kurwego rwa scaly zinc, nta ruswa yangiza amashanyarazi, bityo ikoreshwa rya Zn rikaba ryarahagaritswe ruswa ya Al irahagarikwa.
# 5.Inzira nziza cyane
Amazi yo kuvura Dacromet arashobora kwinjira mubice bifatanye byakazi kugirango bikore ingese.Niba uburyo bwa electroplating bwakoreshejwe, ubuso bwimbere bwumunyamuryango wigituba ntibuba bushyizweho kubera ingaruka zo gukingira.Ariko, kubera ko kuvura Dacromet bikoreshwa mugutwikira kandi bifite uburyo bwiza, birashobora gukoreshwa mugutezimbere ubushobozi bwo kwirinda ingese imbere no hanze.
# 6.Nta mwanda uhari
Iyo amashanyarazi ya zinc, habaho ikibazo cyo gusohora imyanda irimo zinc, alkali, aside chromic, nibindi, bizatera umwanda mwinshi.Ubushyuhe bwa dip zinc zishyushye ni bwinshi, kandi imyuka ya zinc irekuwe na HCL byangiza ubuzima bwabantu.Ibyinshi mubushuhe bwa zinc ubu bigomba gukorerwa kure yimijyi nicyaro.Inzira ya Dacromet yashyizeho umurima mushya wo kurinda ibyuma.Kubera ko kuvura Dacromet ari inzira ifunze, ibintu bihindagurika mugihe cyo guteka ni amazi cyane, ntabwo birimo ibindi bintu byangiza bigenzurwa, kandi bidafite umwanda kubidukikije.
