Can a brushless automatic car wash machine remove heavy road film?

The brushless automatic car washing machine can remove heavy road traffic film without physical contact scrubbing, but the cleaning effect is limited by water pressure. The formula of detergent, soaking time, ambient temperature, and spray coverage range can all affect the softening and cleaning effect of stubborn adhered dirt. For gas stations and chain car wash shops, the difficulty lies in balancing chemical costs, car wash time, and ensuring stable cleaning quality.

The actual conclusion needs to be viewed in different scenarios: a fully debugged and adapted non-contact cleaning solution can remove the vast majority of traffic film, but cannot promise to remove all types of stains. Some sediments require special pretreatment; Under some working conditions, the duration of drug infiltration is insufficient, which limits the cleaning effect. Therefore, when selecting equipment, the type of dirt to be cleaned and the expected surface cleanliness standards should be evaluated first, rather than prioritizing the parameters of the water pump.

Heavy road film is not simply loose dirt

Road traffic film is a thin layer formed by the mixture of fine particulate matter and oily pollutants, including road dust, combustion residues, lubricating grease, and various impurities thrown off by vehicles. In winter, residual road deicing agents may also accumulate; Its composition will dynamically change with traffic flow, weather, driving mileage, and washing cycle.

This is crucial: washing away visible mud on the surface is not the same as removing the underlying gray traffic film. Water pressure can only flush away loose dirt, and oil stains may still remain on the paint surface. After washing the vehicle, it looks clean in a wet state. When the moisture dries, the gray layer on the bottom will appear.

Tar spots, embedded metal debris, hardened insect corpses, and mineral scale belong to another type of stubborn stains. If all of these are broadly classified as' heavy traffic film ', it will form unrealistic acceptance criteria. Conventional automatic car washing is only applicable for assessing pollutants on ordinary road surfaces; Severe specialized decontamination needs to be defined separately.

Judge the spray system at the vehicle, not just at the pump

The rated pressure of a water pump does not necessarily equate to its cleaning capacity. The nozzle model, flow rate, spray angle, distance between the nozzle and the vehicle body, and movement speed collectively determine the actual state of the water flow reaching the surface of the vehicle body. Two devices with similar nominal pressures may have significantly different actual cleaning effects.

During testing and evaluation, special attention should be paid to the areas around the car door sill, tailgate panel, chassis door sill, and rearview mirror. This type of location has a heavy accumulation of pollutants and is difficult to spray and cover. Simply increasing the water pressure of the entire machine will only increase water and energy consumption, and cannot compensate for the problems of spray dead corners or uneven application of chemicals.

It is necessary to verify the drug delivery pipeline and high-pressure flushing conditions. Uneven wetting can cause mottled washing effects, which can easily be mistaken for insufficient detergent concentration. Before increasing the dosage of the medication, it is necessary to first check for nozzle blockage/wear, calibration of the medication injection valve, supply pressure, and whether the control program can achieve complete coverage.

Vehicle recognition and traffic control systems are equally critical. The equipment needs to be compatible with various vehicle models while ensuring safe operation. Using only a small sedan for demonstration testing cannot verify the cleaning performance of the equipment on high body vehicles or different rear end shapes.

Water quality can change both cleaning and the apparent result

The hardness of water quality can affect some detergent systems and easily lead to sedimentation. Even if the road traffic film has been washed clean, the minerals dissolved in the final washing water will still leave water spots after the water evaporates. These two types of problems have different causes, and their solutions also need to be distinguished.

The water cycle system will bring more variables. If the entire treatment and equipment are designed for reuse of reclaimed water, the reclaimed water can be used for some cleaning processes, but whether it can be used depends on suspended solids, residual oil, dissolved substances in the water, and the water treatment process. It cannot be assumed that recycled water is suitable for all pharmaceutical processes and the final rinse with clean water.

Before finalizing the entire plan, it is necessary to confirm what water source is used for each cleaning process, as well as the water quality standards required by equipment and chemical suppliers. Otherwise, it is easy to encounter situations where the detergent is selected based on one water quality, but the actual water quality conditions on site are completely different, resulting in unsatisfactory cleaning results.

Buy an integrated process with clear responsibilities

Equipment, chemicals, and water treatment systems are often evaluated separately, but problems with cleaning often arise at the junction of these systems. Before debugging, it is necessary to clarify who is responsible for adding chemicals, verifying water quality, adjusting cleaning procedures, and investigating situations where cleaning does not meet standards. Chain stores should also do a good job in parameter retention and inspection records, and the cleaning effect cannot be controlled solely by individual skilled hands.

Fanti Precision Equipment provides one-stop car washing solutions for gas stations, car washing chains, and value-added service providers, including fully automatic contactless car washing systems, reclaimed water recycling equipment, car washing agents, and towel drying equipment. When developing such project plans, the focus should be on discussing how to match and jointly validate each component. Drying equipment can optimize the finishing process, but it cannot be relied on to make up for the unwashed traffic film.

As long as the drug formula, spray coverage, and water circulation parameters can work together and stably through actual machine testing, the brushless car washing machine can reliably handle heavy road traffic films. Before finalizing the plan, it is necessary to arrange on-site testing, using actual water sources and agreed upon cleaning standards, and synchronously recording data on various energy consumption and consumables. If you want to achieve qualified results, you need to manually wash or adjust the equipment beyond the parameters allowed by the manufacturer, which means that this process does not meet the requirements.
