In the era of running, have your headlights kept up?

Everyone knows that car headlights will turn yellow after being used for a period of time.

Today, I will tell you why the headlights turn yellow and how to choose the headlights?

The main reason for the yellowing of the surface of the car headlights is the sun exposure, so avoiding the sun exposure is the most direct way to avoid the headlights turning yellow. Wipe the surface of the headlight regularly with a soft cloth to avoid long-term adhesion of dirt. Use alkaline water to clean the headlights. You can use soapy water. After cleaning, wipe it with a polishing agent, and then wax it for care.

For manufacturers of car headlights, how to detect whether the headlights have good yellowing resistance, then use a test box for testing yellowing resistance. Here is a test equipment for yellowing resistance. .

HD-E704 Yellowing Resistance and Aging Test Machine. It can do two kinds of tests: aging and yellowing resistance.

Aging: This machine can promote the deterioration of vulcanized rubber to calculate the rate of change of tensile force and elongation before and after heating. It is generally considered that testing at 70°C for one day is theoretically equivalent to 6 months of exposure to the atmosphere.

Yellow resistance: This machine simulates the atmospheric environment and is exposed to ultraviolet rays from the sun. The appearance change is generally considered to be tested at 50 ℃ for 9 hours, which is theoretically equivalent to 6 months of exposure to the atmosphere.

Features:

1. Ergonomics and simple operation are the main focus of the design. The volume design of the gloss meter is reasonable, and the button operation, screen display and simple navigation menu make gloss measurement easy. One-key operation, automatic calibration at startup, automatic measurement, and storage of test data.

2. The all-metal shell is durable and comfortable, and the instrument meets various international and domestic standards with good quality.

3. Free choice of multiple functional modes, such as: automatic measurement, manual measurement, sampling measurement, statistical measurement, to meet your different needs.

It is recommended that all riders choose engineering plastic alloy materials as much as possible when choosing headlights. Otherwise, the yellowing of the headlights will not only make it unsightly, but also become opaque and reduce the brightness, which will bring a certain degree of danger to car owners who travel at night.
