Dacromet Flange Bolts: Kurwanya Kurwanya Ruswa no Kurwanya Rust Kubisaba Porogaramu 

Dacromet ni sisitemu idafite ingufu za elegitoronike, ishingiye ku mazi ya organorganic coating igizwe ahanini na zinc zuzuye hamwe na flake ya aluminiyumu ikwirakwizwa muri chromium irimo cyangwa chromium idafite ingirabuzimafatizo. Bikoreshejwe muburyo bwa dip-spin, spray, cyangwa dip-drain hanyuma bigakizwa nubushyuhe, igipfundikizo gikora ikintu cyoroshye (mubisanzwe 5-15 mkm), firime imwe, ifeza-imvi ikingira ifata neza cyane munsi yicyuma.

Uburyo bwo kurwanya ruswa bwa Dacromet bukora binyuze mubikorwa bine byuzuzanya:

1. Kurinda inzitizi: Gufunga zinc na aluminiyumu birema ibice byinshi bibuza kwinjira mubushuhe, ogisijeni, na ion zibora.

2.Uburinzi bwihariye (galvanic): Zinc ikora nka anode yigitambo, cyane cyane ikangirika kugirango ikingire ibyuma byimbere ingese.

3.Kwikiza / kwikosora: Oxidation yibicuruzwa bya zinc na aluminiyumu byuzuza micro-kwangirika, bikomeza ubudahangarwa bwo kurwanya ingese.

4.Passivation: Ihuza rya organic organique hamwe na passivating compound bigabanya umuvuduko wibitambo bya zinc, bikongerera ruswa muri rusange.

Kubera ko inzira itarimo gufata aside cyangwa electrolysis, gutwikira Dacromet bikuraho burundu ibyago byo kwinjiza hydrogène - inyungu ikomeye kumashanyarazi akomeye (Icyiciro 10.9, 12.9, na ASTM A490 / F3125). Ibi bituma Dacromet flange ihindagurika haba muburyo bwizewe kandi irwanya cyane ingese no kwangiza ibidukikije.

3. Ibyiza byingenzi bya Dacromet Flange Bolts

3.1 Ruswa idasanzwe no Kurwanya Rust

Dacromet-isize flange bolts isanzwe igerwaho Amasaha 1.000 cyangwa arenga yo gupima umunyu utagira aho ubogamiye (ASTM B117 / ISO 9227) utagaragaye ingese zitukura. Mubisobanuro byinshi, ingese yera itinda kurenza amasaha 240-500, kandi muri rusange imikorere yo kurwanya ruswa iruta inshuro 7-10 kurenza amashanyarazi asanzwe. Ubu bushobozi buhebuje bwo gukumira ingese butuma ubuzima bumara igihe kirekire ku nkombe z’inyanja, inyanja, inganda, na de-icing-umunyu.

3.2 Nta ngaruka ya hydrogène ishobora guterwa

Bitandukanye na electroplating inzira yinjiza hydrogene mubyuma birebire cyane, inzira ya Dacromet dip-spin cyangwa spray ntabwo rwose ari electrolytike. Kubera iyo mpamvu, imbaraga zikomeye za flange bolts zigumana imiterere yubukanishi kandi ntizishobora kuvunika gutinda guterwa no kwinjiza hydrogène - bitanga uburyo bwo kwirinda ingese ndetse n’umutekano wubatswe.

3.3 Gitoya, Igifuniko kimwe hamwe nigenzura ryiza cyane

Ubunini busanzwe butwikiriye buri hagati ya 5 na 15 mm. Iyi firime yoroheje ntabwo ihindura cyane ibipimo byurudodo, yemerera imbuto zisanzwe gukoreshwa nta kurenza. Ipitingi yinjira muri geometrike igoye, insanganyamatsiko, hamwe nuburuhukiro bumwe, byemeza ko birwanya ruswa byuzuye ndetse no kumwirondoro utoroshye.

3.4 Ubushyuhe bwo hejuru cyane hamwe ninyungu zinyongera

Ipfunyika ya Dacromet ikomeza kuba nziza mubushyuhe bukomeza bugera kuri 250-300 ° C, burenze kure imipaka yubushyuhe bwa plaque zinc zisanzwe. Inyungu zinyongera zirimo gusiga amarangi meza, kugenzura coefficient zo kugenzura (cyane cyane hamwe n'amavuta yo hejuru), guhuza bimetallic na aluminium, no kubahiriza amahame menshi yimodoka n’ibidukikije.
