四、产品特点和优势      Features and advantages

1、产品为复合型结构。外壳为隔爆型，内装线路板为本安型。

The structure of product is complex type. The enclosure is flame-proof type, and inner circuit board is intrinsical safety type.

2、铸铝合金外壳，铝合***号为ZL102。采用***的“高温一次压铸”成型工艺，压铸产品表面光滑，金属结构***细密，外壳内部无气泡、无砂眼，抗冲击性能好，产品外壳防爆性能明显提高，且产品上有模具直接压制而成的***性防爆标志及商标。

ZL102 die-cast aluminum alloy Enclosure. After adopting advanced technique, the die-cast enclosure has the features of glazed surface, compact metal structure, no air bubble and sand hole inside the shell, and impact resistance. The explosion-proof capability of enclosure has ***iously improved, and there is permanent Ex mark and label pressed directly by mould in the product.

3、产品通过抛丸机进行表面强化清理等技术处理后（消除表面应力、使产品表面获得一定的粗糙度的光度表面、增强涂层吸附能力、确保涂层质量），采用国内***的高压静电喷塑工艺进行表面喷塑及同行业中***的全自动烘干流水线设备，塑层附着均匀且附着力强，防腐、***化、日照性能明显提高，大大优于喷漆工艺。采用全自动工艺且在产品生产时间上大大地提高。

After the product is treated with surface intensify clearing etc. technique by shot-blasting machine(eliminating the surface stress, enabling the product surface obtain a luminosity surface with certain roughness, enhancing the absorption capability of the coating, and ensuring the quality of the coating), and domestic advanced high-pressure electrostatic plastic-spraying technique and the unique full-automatic drying pipeline equipment in the same industry is adopted, the plastic coating is attached symmetrical and has strong adhesive power. The features of corrosion-proof, oxidation resistance and sunlight performance are improved ***iously, which are much better than paint-spraying technique. Full-automatic technique is adopted and the production time has improved greatly.

4、外壳为螺纹隔爆嵌密封圈结构，防爆性能高，防护等级达IP65。线路板进行本安防爆处理，具有***高的安全级别。

The enclosure is thread flame-proof structure embedded with sealing washer with good capability of explosion-proof. And the degree of protection can achieve IP65. Circuit board is disposed by intrinsical-safety explosion-proof with high safety class.

5、玻璃罩采用钢化玻璃灯罩，抗冲击，防爆性能好，透光率高达90%。有红、黄、蓝等多种颜色可选。

Toughened glass lamp cover is adopted, with good capability of explosion-proof, and the light tran***ittance has achieved 90%. And be equipped with guard net cover, which adopts plastic-sprayed technique after galvanization, with strong corrosion-proof performance. Stainless steel net cover can be supplied according to users’ request.

6、所有外露紧固件均为不锈钢。

   Allthe exposed fasteners are made of stainless steel materials.

7、钢管或电缆布线均可。

  Suitable for steel pipe wiring or cable wiring.
