静电喷漆房

Electrostatic spray painting room

通过高压静电场使涂料微粒带电，吸附至工件表面，涂料利用率提升至85%以上。该技术对金属制品效果显著，但需精准控制湿度（通常要求＜70%），否则易引发放电不均。

By using a high-voltage electrostatic field to charge coating particles and adsorb them onto the surface of the workpiece, the utilization rate of the coating is increased to over 85%. This technology has a significant effect on metal products, but precise humidity control is required (usually<70%), otherwise it may cause uneven discharge.

二、环保升级：VOCs治理技术对比

2、 Environmental Upgrade: Comparison of VOCs Control Technologies

初期投资低，但饱和后需高温脱附再生，运行成本较高。新型蜂窝活性炭将风阻降低40%，适合中小型企业。

The initial investment is low, but after saturation, high-temperature desorption regeneration is required, resulting in higher operating costs. The new honeycomb activated carbon reduces wind resistance by 40%, making it suitable for small and medium-sized enterprises.

RTO焚烧技术

RTO incineration technology

热效率＞95%，VOCs去除率超99%，适用于大型连续作业场景。其双室蓄热设计使天然气消耗量减少60%，但需配合LEL浓度监测系统防爆。

Thermal efficiency>95%, VOCs removal rate over 99%, suitable for large-scale continuous operation scenarios. Its dual chamber thermal storage design reduces natural gas consumption by 60%, but requires the cooperation of LEL concentration monitoring system for explosion prevention.

生物降解技术

Biodegradation technology

利用微生物分解有机废气，运行成本仅为传统方法的1/3。最新菌种培育技术将甲苯、二甲苯处理效率提升至80%，但环境适应性较弱（温度需维持在25-35℃）。

By utilizing microorganisms to decompose organic waste gas, the operating cost is only one-third of traditional methods. The latest strain cultivation technology has increased the efficiency of toluene and xylene treatment to 80%, but the environmental adaptability is weak (temperature needs to be maintained at 25-35 ℃).

三、智能化改造的三大方向
