Does Car Glass Water Repellent Damage the Glass?

If used incorrectly, it may not only fail to repel water but also cause the glass to become blurry. Some low-quality water repellents can even make the wiper blades slip. If applied unevenly, it can prevent the wiper blades from cleaning the glass effectively. Here is some additional information: 1. Function: When sprayed on the glass, car glass rain repellent forms a nano protective film on the surface. This film has a hydrophobic effect, preventing the formation of a water film and maintaining the clarity of the glass. The rain repellent is non-corrosive and contains silicone resin and fluorinated organic compounds that repel water, reducing the contact area between water droplets and the glass, making it easier for the wind to blow them away. 2. Working Principle: During the application of car glass water repellent, special fluorine ions are combined with the addition of F12 super wear-resistant agents, forming an ultra-thin special coating layer on the windshield. This creates a strong water-repellent effect, causing rainwater to quickly form droplets upon contact with the glass and be blown away by the wind generated while driving.

What Causes Poor Cooling Performance in a Van's Air Conditioning System?

The reasons for poor cooling performance in a van's air conditioning system include insufficient or excessive refrigerant, uncleaned air conditioning components, and excessive moisture in the dryer tank. Below are detailed explanations: 1. Insufficient or excessive refrigerant: The refrigerant's role is to transfer heat within the refrigeration system to achieve cooling. The air conditioning system requires a specific amount of refrigerant for optimal performance. If the refrigerant level is too low, it won't provide adequate cooling, or if it leaks, the refrigerant can deteriorate. Lower-quality refrigerants degrade faster, leading to poor cooling performance. 2. Air conditioning cleaning: There are two main components that need cleaning: the air filter and the air conditioning ducts. The air filter's purpose is to trap dust from the air, ensuring clean airflow inside the vehicle. If the air filter becomes too dirty and clogged, cold air cannot circulate properly, resulting in a lack of cooling. 3. Excessive moisture in the dryer tank: The dryer tank in the air conditioning system is crucial as its primary function is to absorb excess moisture from the pipelines. If the dryer tank is damaged and cannot absorb the excess moisture, the moisture can freeze in the expansion valve's throttle orifice, blocking the refrigerant flow and significantly reducing cooling efficiency.

What is the voltage of a car alternator?

The normal voltage range of a car alternator after starting is "15.3V-12.8V"; below is relevant information about car alternator voltage: 1. Normal alternator voltage conditions: When the vehicle's air conditioning is operating and other electrical devices are used excessively, the alternator voltage may drop below 12.8V. At this point, the vehicle draws current from the battery and cannot charge the battery. After starting, the battery voltage is essentially equal to the alternator voltage, differing only by the line loss voltage from the alternator to the battery. When the vehicle is not started, the normal battery voltage range is 13.8V-12.8V. 2. Introduction to the alternator: The car alternator is the main power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally (above idle speed) and simultaneously charge the battery. Based on the three-phase stator winding of a conventional AC generator, additional winding turns are added with lead-out terminals, and an additional three-phase bridge rectifier is included. At low speeds, the output is from the original and additional windings in series, while at higher speeds, only the original three-phase winding provides the output.
