Today, the editor of Hefengli Dry Ice Decontamination Equipment Co., Ltd. has sorted out some knowledge about dry ice cleaning services for you, and now I will share it with you.

The application of dry ice blasting on the spraying line of the painting workshop has been a mature application after several years of accumulation and equipment upgrades, but it is still an unfamiliar technology for those who do not understand dry ice blasting.

The product needs to be pre-treated before spraying. The product needs to be washed before entering the spray booth for spraying. In the traditional form, in addition to manual wiping, it is pre-washing. As can be seen in the figure above, the equipment for pre-washing is relatively complicated.

It roughly consists of pre-degreasing, degreasing, washing 1, washing 2, pure water washing, water blowing, water drying, and cooling. Not only is the equipment huge, the energy consumption is large, the equipment cost is high, and it is not environmentally friendly, then dry ice cleaning should be avoided. this series of problems.

So can dry ice blasting replace water washing? We have done a lot of tests and cases. After cleaning the product, we directly spray the primer, topcoat, and varnish. After drying the parts, we test the quality of the paint surface, from the adhesion, the number of dust particles, and shrinkage cavities. . . . The average is basically the same as the pre-treatment method of water washing. According to this analysis, using dry ice cleaning instead of water washing can achieve the same level of both.

Some of the traditional water washing in the spraying line even take up one-third of the whole spraying line, so for factories with limited space, the advantages are more obvious.

Traditional water washing equipment consists of many auxiliary equipment, including water pumps, heaters, filters, valves, nozzles, fans, and pure water equipment. . . . And so on, equipment manufacturing costs and later maintenance costs are higher.

The composition of dry ice cleaning equipment is relatively simple, consisting of dry ice cleaning machine, pipelines, etc., which reduces a lot of equipment and later maintenance of equipment, saves space and saves costs.

In terms of equipment operating costs, we took the usual car bumper spraying as an example to make a rough comparison for your reference, and to demonstrate with the actual situation. If there is any inaccurate data, please contact us to discuss modification and update.

In the above table, the cost consumption of a single product is obtained by adding up various expenses and dividing by the output. If the traditional pre-washing treatment is used, the processing cost of a single bumper is 4.69 yuan/piece.

If dry ice pre-treatment is used, use the same method to add up the cost consumption, and then the average cost consumption on a single product is 1.31 yuan/piece.

From this point of view, regardless of equipment cost, energy consumption, floor area and operating cost, dry ice blasting has certain advantages.
