Kau ʻia ma 2016-06-22 ʻO ka Zinc flake coating kahi ʻano hou o ka corrosion resistance coating, ua hoʻohana nui ʻia, ʻo ka zinc flake coating kaʻina nui ka mea kumu, hoʻohaʻahaʻa, derusting, uhi, preheating, curing, cooling.
1. Degreasing: pono e degreased ili workpiece, maʻamau i ekolu ala: organic solvent degreasing, wai-ma muli degreasing agent, kiʻekiʻe wela carbonization degreasing.Whether degreasing pono pono, e pili pono i ka adhesion o ka uhi.
2. Derusting a me ka deburring: ka mea hana me ka rust a burr ua kapu loa i ka uhi pololei, pono e hele i ka derusting a me ka deburring kaʻina hana, keia kaʻina hana i oi aku ka hana mechanical, e pale aku i ka waikawa e pale hydrogen embrittlement.
3. Ka uhi ʻana: ka mea hana ma hope o ka degreasing a me ka derusting pono e ʻuʻu ʻia, e kāpī ʻia a palaki ʻia asap.
4. Pre-wela: workpiece me ka zinc flake uhi pena ma luna o ka ili e pono pre-heating 10-15 minuke asap ma lalo o ka mahana o 120 + 20 ℃, e hana i ka uhi wai wai evaporation.
5. Curing: workpieces ma hope o pre-heating pono ho'ōla ma lalo o 300 ℃ kiʻekiʻe wela, ho'ōla manawa 20-40 minuke, hiki no hoi ke kupono e hookiekie i ka manawa hoola.
6. Hooluu: Pono e hooluolu piha i na mea hana ma hope o ka ho'ōla 'ana e ka 'ōnaehana ho'olu'u no ka ho'oponopono hou 'ana a i 'ole ka nānā 'ana i ka waiwai.
