Handle before the manual process and automatic pre-treatment process, which is divided into automatic spraying and automatic immersion two processes. The workpiece must be surface-treated to remove the oil before stripping. In this section of the liquid used more, mainly derusting agent, degreasing agent, table swap, phosphating agent and so on.
In the painting line before the processing section or workshop, the first thing to note is to develop the necessary strong acid and alkali purchase, transportation, custody and use system, to provide workers with the necessary protective clothing, safe and reliable dressing, handling equipment, and The development of emergency measures in case of emergency, rescue measures. Second, in the coating production line before the treatment section, due to the existence of a certain amount of waste gas, waste and other waste substances, so in environmental protection measures, must be equipped with exhaust, drainage and waste treatment device.
Pre-treated workpiece quality, due to pretreatment and coating production line process is not the same, its quality when there are differences. Handling the workpiece, the surface oil, rust to do, in order to prevent a short time again rust, generally should be in the pre-treatment after a few processes, the phosphating or passivation treatment: before the powder, The workpiece is dried to the surface of the water. Small batch production, the general use of natural dry, dried, dry. For high-volume flow of operations, generally take low-temperature drying, the use of Oven or bake Road.
For small batch parts, the general use of manual dusting device, and for large quantities of workpieces, the general use of manual or automatic dusting device. Whether it is manual powder or automatic powder, it is very important to keep quality off. To ensure that the workpiece was sprayed with uniform powder, the same thickness, to prevent thin spray, leakage spray, wipe and other defects.
In the coating production line cited this process, should also pay attention to the hook part of the workpiece, before entering the curing, as far as possible will be attached to the powder blowing off to prevent the excess powder on the hook curing, and some cured before the powder There are difficulties, it should be promptly stripped on the hook has been cured on the film, so as to ensure good hook hook, in order to facilitate the next batch of easy to powder.
This process should pay attention to the following matters: spray a good workpiece, if it is a small batch of single-production, into the curing furnace before the attention to prevent falling powder, if the phenomenon of powder, should be timely filling powder. Baking strict process and temperature, time control, pay attention to prevent color, over baking or too short time caused by insufficient curing.
For large quantities of automatic delivery of the workpiece, in the boring Road before the same to carefully check whether the leak, spray or local powder phenomenon, such as the discovery of non-qualified pieces, should be good to prevent the entry into the bake Road, as far as possible to take heavy spray. Such as individual parts due to thin spray failed, in the curing of the bake Road can be re-spray again after curing.
The so-called coating refers to the metal and non-metallic surface covered with protective layer or decorative layer. Painting line has experienced from the manual to the production line, to the automatic production line of the development process, the degree of automation is getting higher and higher, so the application of coating production line is more and more extensive, and deep into the national economy in many areas.
Painting Pipeline Engineering Application Features:
Painting line equipment for the workpiece surface painting, spray treatment, used for single or small batch of workpiece painting operations, with hanging conveyor, rail car, ground conveyor and other transport machinery to form transport operations.
Engineering process layout:
1, spray line: the conveyor chain - spray - drying (10min, 180 ℃ -220 ℃) - cooling - the next
2, paint line: the conveyor chain - electrostatic dust - primer - leveling - topcoat - leveling - drying (30min, 80 ℃) - cooling - the next
Paint spray mainly oil spray paint room, curtain water spray booth, widely used in bicycles, automotive leaf spring, large loader surface coating.
