详细信息
| | 涂装生产线前处理设备 涂装生产线前处理设备是表面处理常用的设备，为涂装前对工件表面之氧化皮、铁锈、油脂、尘土等污垢物进行清洗的工序，使涂装粉体与金属表面结合牢固、附着力强、从而使产品获得更高的品质，延长产品的使用寿命。 前处理分为喷雾式、浸液式、潜泳式或结合式处理，可视工件及具体生产要求选择处理方式。一套完整的前处理生产线设备由槽体、喷淋系统、加热控温系统、通风系统、磷化液沉淀除渣系统、喷淋室体和照明装置组成。该生产线可实现全自动控制。 前处理设备一般多采用喷淋式多工位前处理机组形式，其原理是利用机械冲刷加速化学反应来完成除油、磷化、水洗等工艺过程。 钢件喷淋式前处理的典型工艺是：预脱脂、脱脂、水洗、水洗、表调、磷化、水洗、水洗、纯水洗。 前处理还可采用抛丸清理机，适用于结构简单、锈蚀严重、无油或少油的钢件，其优点是无水质污染。 。 |
Pretreatment equipment of coating production line
The pretreatment equipment of the coating production line is a common equipment for surface treatment. It is a process to thoroughly clean the scale, rust, grease, dust and other dirt on the workpiece surface before coating, so that the coating powder can be firmly combined with the metal surface with strong adhesion, so that the product can obtain higher quality and prolong the service life of the product.
Pretreatment can be divided into spray type, immersion type, submerged type or combined type. The treatment method can be selected according to the workpiece and specific production requirements. A complete set of pretreatment production line equipment consists of tank body, spray system, heating and temperature control system, ventilation system, phosphating solution sedimentation and slag removal system, spray chamber body and lighting device. The production line can realize full automatic control.
Pre treatment equipment generally adopts spray type multi station pre-treatment unit. Its principle is to use mechanical scouring to accelerate chemical reaction to complete the process of oil removal, phosphating, water washing and so on.
Typical spray pretreatment processes for steel parts are pre degreasing, degreasing, water washing, water washing, surface conditioning, phosphating, water washing, water washing and pure water washing.
The pre-treatment can also adopt shot blasting machine, which is suitable for steel parts with simple structure, serious corrosion, no oil or little oil. Its advantage is no water pollution.
