"Water ingress" promotes transformation - the process of improving water-like coating of bicycles.

In recent
, with the improvement of national living standards, cars have quickly entered thousands of households. Not only "north to wide" such a metropolis blocking, blocking, blocking, even many small counties and cities are currently serious traffic jam phenomenon. Another problem is that the pollution of the air caused by automobile exhaust emissions, especially the haze in the north, has aroused the concern of the whole country about environmental

. Both Jinshan Yinshan and Green Water Green Mountain have become the consensus of everyone, environmental awareness and concepts continue to strengthen. Bicycles as a green travel sports, transportation, but also attracted more and more people to participate in the cycling army, cycling population greatly increased.
the basic materials of bicycles for steel, aluminum alloy, carbon fiber, etc. , in order to protect, especially in order to pursue aesthetics, all have to be coated. Traditional coating to go through pre-treatment, painting, drying and other processes, and these processes often bring different pollution to the water environment, air environment.
talk about environmental protection, then the editor-in-chief talks about the water-like spraying of bicycles. First of all, the physical and chemical properties are confirmed by hand air spraying, and the storage stability of the original paint is confirmed, including the storage stability of the original paint and the diluted storage stability. Bicycle coating is generally 4 spray 5 baking process. Most of the paint spraying did not force the air, for natural wind, forced exhaust, did not regulate the temperature and relative humidity of the air, but by adjusting the rate of paint volatility in different seasons to adapt to changes in ambient temperature and humidity; The advantage of this process is that the relative operating cost is low, but the construction of the coating is wide. And water-based coating conditions, requiring equipment to stainless steel material, air temperature in (23±2) degrees C, relative humidity (65±5),, leveling room to about 60 degrees C, oven to heat up in stages, construction conditions are higher, all of which will increase the cost of bicycle coating. To this end, generally will take the use of paint spraying process, reserved for improvement space, first adjust the water-based paint construction adaptability, the last last to adjust the process and hardware equipment program for verification. Taking a bicycle spraying enterprise as an example, they chose to increase the temperature and relative humidity control between the coating room, the temperature is between 15 to 30 degrees C, the relative humidity is below 80%, the line speed is 2 to 3m/s, the flow flat time is 10 to 15min, the bottom medium coating baking curing condition is 115 degrees C/20min, the baking curing condition of the varnish is 125 degrees C/20min. Water and oil sharing process, but also for the paint oil to water for valuable development time, and finally, they through testing timely adjustment of the paint formula, improve the water-based paint dilution easy to precipitate, spraying easy to foam, drooping, paint film water resistance, low gloss, film thickness, impact resistance and other issues, construction and materialization performance are comparable to paint.
For the environmental protection process of bicycle coating, the pre-treatment uses phosphorus-free degreasing, acid mist inhibitors, silane tantapenane salt skin film, chromium-free passivation and other processes to reduce air pollution and water pollution. Spraying process part, mainly developed into high solid sub-coatings, water-based coatings, low-temperature cured powder coatings and liquid gold oil several, different product positioning, different order patterns, can take different environmental protection coatings and coating process. These explorations and practices are of reference to the relevant technological transformation of the industry.
