涂装生产线在生产时应该注意什么?

一、涂装生产线上应注意被涂物件的装挂。预先通过试浸来设计挂具及物件在涂装生产线上的装挂方式,保证工件在浸涂时处于位置。被涂物的平面应接近垂直,其他平面与水平呈10°-40°角,使余漆的涂装面上能够较流畅地流尽。
1、 Attention should be paid to the installation and hanging of coated objects in the coating production line. In order to ensure the best position of the workpiece in the coating production line, the hanging mode of the hanger and articles in the coating production line is designed in advance through the trial immersion. The maximum plane of the coating should be close to vertical, and the other planes should be at an angle of 10 ° to 40 ° with the horizontal, so that the remaining paint can flow out smoothly on the coating surface.
二、在涂装生产线上涂装时为防止溶剂在车间内的扩散和尘埃落入漆槽内,浸漆槽应保护起来。
2、 In order to prevent the diffusion of solvent in the workshop and dust falling into the paint tank, the dip tank should be protected during painting production line.
三、大型物件在涂装生产线上浸涂后,应待溶剂基本挥发后再送入烘房。
3、 After the large objects are dipped in the coating production line, they should be sent to the drying room after the solvent is basically volatilized.

四、涂装时要不断注意涂料粘度的测定,每班应测定1-2次粘度,若粘度增高超过原粘度的10%,就应及时补加溶剂。添加溶剂时,应停止浸涂作业。搅拌均匀后,测定粘度,然后再继续作业。
4、 Pay attention to the measurement of coating viscosity during coating, and measure the viscosity 1-2 times per shift. If the viscosity increases more than 10% of the original viscosity, the solvent should be added in time. When adding solvent, dip coating should be stopped. After mixing evenly, determine the viscosity, and then continue the operation.
五、漆膜的厚度主要决定于涂装生产线上物体提升的速率以及漆液的粘度。在按上述要求控制了漆液的粘度后,涂装生产线应按照漆膜30um左右的限速度,根据不同的设备,实验确定合适的提升速率。按此速率均匀地提升被涂物件。提升速率快,漆膜薄;提升速率慢,漆膜厚且不均匀。
5、 The thickness of paint film is mainly determined by the speed of object lifting and the viscosity of paint liquid. After controlling the viscosity of the paint according to the above requirements, the coating production line should determine the appropriate lifting rate according to the maximum limit speed of about 30um film and different equipment. Lift the coated object evenly at this rate. The results show that the coating film is thin and the lifting rate is fast, and the paint film is thick and uneven.
六、在涂装生产线上进行浸涂操作时,有时造成被涂上、下部的漆膜具有厚度差异,尤其是在被涂物的下边缘出现肥厚积存。为提高涂层的装饰性,在小批量浸涂时用刷子手工除掉多余积存的漆滴,也可用离心力或静电引力设备除掉这些漆滴。
6、 When dip coating is carried out on the coating production line, sometimes the thickness difference of the coating film between the upper and lower parts is caused, especially in the lower edge of the coating. In order to improve the decoration of the coating, the residual paint drops can be removed manually by brush or centrifugal force or electrostatic force equipment.
七、在涂装生产线上浸涂木制件时,注意时间不能太长,以免木材吸入过量的涂料,造成慢干和浪费。
7、 In the coating production line, pay attention to the time should not be too long, in order to avoid wood inhalation of excessive paint, resulting in slow drying and waste.
八、加强通风设备,防止溶剂蒸气的危害;注意防火措置的安排和定期检查涂装生产线。
8、 Strengthen ventilation equipment to prevent the harm of solvent vapor; pay attention to the arrangement of fire prevention treatment and regular inspection of coating production line.
