Why Changxian

A manufacturer, not a trading desk

Everything that matters in electronic chemicals — raw material control, licensing, formulation capability and technical service — we hold in-house.

  • In-house resin synthesis

    Resin is the critical raw material for electronic chemicals. We synthesise our own, which secures batch consistency, cost control and supply continuity.

  • Full hazardous-chemical licensing

    Holding both a hazardous chemicals production licence and an operating licence, with logistics partners qualified for hazmat transport nationwide.

  • R&D and custom formulation

    An enterprise R&D centre plus dedicated waterborne-resin and PPS laboratories. 16 invention patent applications, 14 granted.

  • Certified technology platform

    National High-Tech Enterprise, Zhuhai Key Enterprise Technology Centre, and the Guangdong PPS Materials Engineering Research Centre.

  • 7,000+ customers

    Long-term partnerships with more than 7,000 customers across China and export markets, supported by experienced sales and technical engineers.

  • Full-chain product support

    From cleaning and soldering to insulation, protection and processing — one supplier covers the whole production chain, cutting qualification overhead.

Industries

Materials for demanding environments

Our products are specified where failure is expensive: data centres, new-energy vehicles, photovoltaics, aerospace, medical devices and precision manufacturing.

长先新材拥有完整的危化品生产与经营资质,包括危险化学品安全生产许可证与危险化学品经营许可证。同时,公司与具备危化品运输资质的专业物流企业合作,确保产品安全合规地输送至全国各地。

什么是三防漆?

三防漆是一种用于保护电子设备的特殊涂料,名称来源于它的三个主要功能:防潮、防尘、防腐——其目的都是让电子设备能够正常工作,避免故障或损坏。三防漆由高分子材料制成,可粘附在电路板或电子元器件表面形成一层薄保护膜,隔绝水分、灰尘、氧气等有害物质,防止短路、锈蚀与老化。除三重防护外,它还能提升绝缘性能、防止漏电与电晕现象,抵抗酸碱、盐雾与硫化侵蚀,并适应高温、低温、高湿等极端环境变化。

三防漆有哪些类型?

长先新材的三防漆提供丙烯酸、聚氨酯、有机硅和水性四种体系,可根据防护等级与工艺条件选择:丙烯酸体系固化快、成本低、易返修,适合一般消费电子;聚氨酯体系耐化学侵蚀与耐溶剂性能最好,适合汽车电子与工业控制;有机硅体系耐温范围最宽(-55 – 200 °C)、柔韧性优异,适合高低温交变与振动环境;水性体系以水为稀释剂,VOC 排放低,适合环保要求严格的产线。

三防漆的应用领域有哪些?

三防漆的应用领域非常广泛,几乎涉及所有电子设备及相关行业,包括:家用电器(电视、冰箱、洗衣机、空调)、照明灯具(路灯、太阳能灯、LED 灯)、电工电气(变压器、开关、插座、线路板)、安防器械(摄像头、报警器、门禁系统)、新能源(风力发电机、太阳能电池板、充电桩)、军工(导弹、雷达、卫星)、医疗(心脏起搏器、人工耳蜗、血糖仪)、航空(飞机、无人机、火箭)、船舶(轮船、潜艇)、消费电子(手机、电脑、平板)、汽车电子、仪器仪表、电源设备以及轨道交通等。

冷板式冷却液的电导率是多少?

长先新材冷板式冷却液的电导率(25 °C)控制在 ≤ 5 µS/cm。低电导率是液冷系统的关键安全指标:一旦管路或快接头发生微渗漏,低电导率冷却液不会在带电部件上形成导电通路,可显著降低短路与设备损坏风险。具体数值随机型略有差异,请以随货技术数据表(TDS)为准。
