伸缩移动喷漆房是一种可以在使用时自动展开形成封闭或半封闭的环保喷漆房，不需要使用时收缩合拢到一处的特殊环保喷漆房装置，他是先进无尘喷漆房的设计理念及技术的集成，使其应用范围非常广泛。而固定式喷漆房采用岩棉彩钢板制作，保证喷漆房安全可靠。采用干式漆雾过滤棉装置净化和湿式无泵水幕漆雾过滤器净化两种净化方式工作的不能搬动的涂装设备。伸缩移动喷漆房与固定式喷漆房相比优势主要体现在以下几方面：
Telescopic mobile spray booth is a special environmentally friendly spray booth device that can automatically unfold to form a closed or semi closed spray booth during use, and can be shrunk and closed in one place when not in use. It integrates the design concept and technology of advanced dust-free spray booth, making its application range very wide. The fixed spray booth is made of rock wool colored steel plates, ensuring the safety and reliability of the booth. Painting equipment that cannot be moved and operated using two purification methods: dry paint mist filter cotton device purification and wet pump free water curtain paint mist filter purification. The advantages of telescopic mobile spray booth compared to fixed spray booth are mainly reflected in the following aspects:
两者厂房大小及利用率
The size and utilization rate of both factories
（1） 固定喷漆房是固定不动，这就限制了厂房的用地上不能在自由使用
(1) The fixed spray booth is fixed and immovable, which limits the free use of the factory land
（2） 喷砂房使用注意事项
(2) Precautions for using sandblasting room
我们使用喷砂房来完成喷砂工艺，使用者可以使用防护服的安全措施来防止受到磨料的冲击，并且通风装置通过头盔给操作者能提供新鲜空气。所以如今许多的大型企业都安装了自己的喷砂房。接下来小编就主要向大家介绍一下在使用喷砂房时应注意哪些事项？具体总结如下：
We use sandblasting rooms to complete the sandblasting process. Users can use safety measures such as protective clothing to prevent impact from abrasives, and ventilation devices can provide fresh air to operators through helmets. So now many large enterprises have installed their own sandblasting rooms. Next, the editor will mainly introduce to you what precautions should be taken when using sandblasting rooms? The specific summary is as follows:
1、 喷砂房的排风量一般略低于送风量，使其喷砂房内气压需处于正压，以避免设备外面未经净化 的空气串入喷砂房内。
1. The exhaust air volume of the sandblasting room is generally slightly lower than the supply air volume, so that the air pressure inside the sandblasting room needs to be at a positive pressure to prevent unprocessed air from flowing into the sandblasting room outside the equipment.
2、 在通道式喷砂房和静电喷砂房中应设置有自动灭火设备。若一旦发生事故，可以促使操作人员尽快脱离险境；
2. Automatic fire suppression equipment shall be set in the channel type sand blasting room and electrostatic sand blasting room. If an accident occurs, it can prompt the operator to escape the danger as soon as possible;
3、 在设备的整个系统中应有警报装置，另外在手工喷涂场合也应当有配备自动喷头和灭火器，确保工艺现场的安全。
3. An alarm device should be installed throughout the entire system of the equipment, and automatic nozzles and fire extinguishers should also be equipped in manual spraying situations to ensure the safety of the process site.
4、 由于喷砂房内极易被雾污染，所以在喷涂过程中每周应当进行清扫一次。
4. Due to the high risk of fog contamination in the sandblasting room, cleaning should be carried out once a week during the spraying process.
5、 湿式喷砂房须经常检查清洗喷嘴、水分离器、床面等，还须定期检查清扫排风机叶片，保持干净。
5. The wet sandblasting room requires regular inspection and cleaning of nozzles, water separators, bed surfaces, etc., as well as regular inspection and cleaning of exhaust fan blades to maintain cleanliness.
6、 大型喷喷砂房的排风量大，要维持喷砂房内的气温处于的工作范围，同时考虑排风能否循环使用；
6. The exhaust air volume of large sandblasting rooms is large, and it is necessary to maintain the temperature in the sandblasting room within the optimal working range, while considering whether the exhaust air can be recycled;
7、 喷砂在专用喷砂机中进行。喷砂机用的新砂应晒干过目，清除掉砂中杂质，方可使用。
7. Sandblasting is carried out in a dedicated sandblasting machine. The new sand used in the sandblasting machine should be dried and thoroughly cleaned of impurities before use.
8、 喷砂用的硅砂粒度为0.5~1mm(20~40号)，压缩空气压强0.3~0.66Mpa（2~6公斤/厘米2）。
8. The particle size of silicon sand used for sandblasting is 0.5-1mm (20-40 grit), and the compressed air pressure is 0.3-0.66Mpa (2-6 kg/cm2).
9、 喷砂过程中，发现有裂纹、碰伤等质量问题要及时挑出，并上报以便及时处理。
9. During the sandblasting process, quality issues such as cracks and bumps should be promptly identified and reported for timely resolution.
10． 为了避免受伤，操作者操作时必须要穿戴好防护用品
To avoid injury, operators must wear protective equipment during operation
