Car wash sprays are not always good for cars. Some types of car washes have an abrasive effect on the paint due to excessive pressure and even carry the risk of scratching if harsh chemicals are applied.
The key to achieving excellent washing performance is a strong and uniform effect. This also means using less water. High-pressure nozzles used by car cleaning companies offer highly effective spraying. To prove this, comparative tests are carried out by the manufacturers. In these tests, it is determined that the nozzles provide an equally high impact across the spray fan. However, another aspect of this business is the risk of paint abrasions and scratches on the vehicles. Effect tests of car wash sprays are carried out in advanced laboratories.
Generally, impact tests are performed at 70 bar pressure with a spray directed onto an impact sensor grid. The grid is mounted vertically. Distances from the sensor are adjusted to obtain a fan spray width. The impact pad contains sensors, each recording 50 readings per second. Spray tests are run for 8 seconds, making a total of 400 readings for each nozzle.
In short, spray impact testing is applied to measure a material's resistance to water penetration when in contact with sprayed water. These tests are also applied to car wash sprays. The car wash spray gun used is manufactured from premium metal, known for its robustness, durability, and reliable performance. However, the force of the water jet carries the risk of damaging the car's paint. Spray testing is performed in a standard chamber with specialized testing methods in advanced laboratories. The system is based on the American Society of Automotive Engineers (SAE) specification requirements used for electronics, housings, and automotive parts. This specification includes details regarding nozzles, rotating spray arms, and product specifications. Drip and car wash tests are also defined. This test standard features spray arms with adjustable pressure and volume output.
