Xylan 涂层是一种耐磨损,不粘,耐高温, 持续性的腐蚀环境中应用的保护微涂层。它区
别于其他传统的含氟聚合物的一个重要点在于它是复合材料。
Xylan is a thin, continuous, protective barrier that resists chipping, galling, cold flow, temperature extremes and weathering in a wide range of corrosive environments. That’
s differs from traditional Fluoropolymer coatings in one very impartment aspect that they are composite materials.
Xylan 的多用途特性在作为螺栓和螺帽的涂料表现最佳，在轻易安装，防腐蚀和轻便拆除方
面都显示出无比的特性。
Xylan multi-purpose characteristics of bolts and nuts as the best performing coatings, in the easy installation, removal of anti-corrosion and light areas have shown tremendous character.
Xylan涂层在防海水腐蚀,抗化学品腐蚀,抗磨损等方面表现出色。盐雾时间最高可达 1000
多小时。Xylan的涂层薄但是却具有自润的性能,特备适用于水下精密设备配合的表面防腐
蚀,BOP,管汇,航空和航天制造工业,风力发电等。
Xylan coating is excellent in seawater corrosion prevention, chemical resistance, and wear prevention. The salt spray test is higher than 1000 hours. The thin film which is suitable for underwater precise equipment surface corrosion prevention, it’s including
BOP, pipeline,voyage spaceflight manufacturing industry, wind power generation and so on.

热镀锌
热镀锌是一种有效的金属防腐方式,主要用于各行业的金属结构设施上。是将除锈后
的钢件浸入500?左右融化的锌液中,使钢构件表面附着锌层,从而起到防腐的目的。
一般用于大量输电塔、通讯塔, 机械交通, 热工, 建筑, 电力,等。
Hot-dip galvanizing is an effective method of metal anti-corrosion is mainly used in various sectors of the metal structure facilities. Is to rust the steel parts after 500 ? or so immersed in the melting of zinc solution, so that the surface adhesion of zinc layer of steel members, which play an anti-corrosion purposes. That’s generally used to the large number of transmission towers, communication towers, machinery and transport, thermal engineering, construction, electricity, and so on.
热镀锌工艺流程,成品去油-水洗-酸洗-清洗-助溶剂-烘干-镀锌-冷却-完工
Hot-dip galvanizing process: alkali washing - washing - acid-washing- cosolvent (NH4Cl+ZnCl2)-Dry- Hot-dip-finish
特点characteristic
1、处理费用低 low price
2、持久耐用(大于50年以上而不必修补)
Durable (larger than 50 years and don’t need patch)
3、可靠性好good of reliability
4、镀层的韧性强good of toughness
5、全面性保护 all-round protect
6、省时省力 save time and labors lose

达克罗
达克罗涂层欧美称DACROMET 日本称DACROTIZED 是美国于20 世纪70 年代发明的
一种新型表面技术.该涂层将被处理的零件浸入或刷涂达克罗处理液中然后经烘干烧结在零
件表面形成一层含有锌和铬耐蚀膜层.该涂层在处理过程中具有优良的耐蚀性无氢脆以及无
污染等特点.
DACROMET is named by Europe and USA, Japan said DACROTIZED that is a new type of surface technology has been invented by USA at 70 years the United States in the 20th century. The coating will be processed parts immersion or brushing DACROMET liquid and then sintered by drying in the parts formed on the surface layer of corrosion resistant coatings containing zinc and chromium. In the process of the coating has excellent corrosion resistance, as well as pollution-free hydrogen, and so on.
6μm 厚的涂层基体为低碳钢经500 hrs 中性盐雾试验不生锈可达1 200 hrs 不生锈电镀锌
经铬酸钝化后出现红锈时间不超过300 hrs. 达克罗的应用范围很广,一般用于 汽车摩托
车,电器电子,地铁隧道、铁路及电气化铁路的金属件,桥梁高架、高速公路的金属件,输
配供电的金属和结构件。
6μm coated low carbon steel substrate for the neutral salt spray test after 500 hrs does not rust up to 1 200 hrs does not rust zinc chromate passivation by red rust after less than 300 hrs. Dacromet a wide range of applications, generally used in auto, electrical and electronics, subway tunnels, railways and electrified railway metal parts, elevated bridges, highways metal parts, power transmission and distribution of metals and structural parts.
