Invisible car clothing product performance test project

Apr 25, 2024

The products of high-quality car clothing brands often undergo comprehensive and strict performance and quality testing before entering the market to ensure the quality of the car clothing and consumer rights.

In the performance test of invisible car clothing products, you can often hear an item called "double 85" test. So what is the "double 85" test? In addition to the "double 85" test, what other test items will invisible car clothing undergo? Woolen cloth?

 

1. "Double 85" test

 

The "double 85" test refers to the aging test performed on the test body when the environment is set to a temperature of 85°C and a humidity of 85%, which is a harsh environmental reliability test. By comparing product performance changes before and after the aging test, the stability and endurance of the product in harsh environments of high temperature and high humidity are tested.

 

Testing purposes

 

Through the "Double 85" test, the weather resistance stability of the car clothing base material can be tested under high temperature and high humidity conditions, ensuring that the base material can maintain good performance in harsh environments and will not suffer from problems such as hydrolysis and cracking.

 

Test meaning

 

In summer, when the outdoor temperature is high, the surface temperature of car paint is often as high as 60°C when exposed to sunlight, and the surface of some dark car paints can even exceed 80°C. In addition, air humidity in some areas is often high due to weather or geographical location factors.

 

The "Double 85" test simultaneously simulates the impact of these two environmental factors on the product, and tests the high temperature and humidity resistance of the car jacket to ensure that the car jacket can maintain stable and excellent performance in the real environment, which is of practical significance.

 

2. Mechanical property testing

One of the core functions of invisible car clothing is its ability to resist scratches, and this tests the physical and mechanical properties of the car clothing. In order to ensure the physical protection performance of invisible car clothing, the product usually needs to undergo the following tests:

 

Breaking strength test
Elongation at break test
Puncture resistance test
gravel impact test
Tensile deformation curvature test

 

Through stretching, puncture, stone impact, etc., the wear resistance, scratch resistance, and impact resistance of the car clothing can be judged to ensure that the car paint can be protected from flying sand and rocks, accidental scratches, malicious scratches, etc. damage.

 

3. Anti-fouling and corrosion resistance test

In the car environment, cars are often corroded by various stains and corrosive substances. In order to ensure that the beauty of the paint surface can be maintained after the invisible car clothing is installed, the following tests are usually carried out on the product:

 

Stain resistance test
Dye resistance test
Corrosion resistance test

 

Through the above tests, the corrosive penetration effects on the surface of the car clothing caused by rain, bird droppings, insecticides, chemicals, acid and alkali reagents, etc. can be simulated, thereby preventing the surface of the car clothing from being tarnished or even leaving spots.

 

4. Weathering stability test

 

Faced with long-term exposure to wind, sun, and rain, invisible car clothing must ensure good weather resistance and stability in order to protect the safety of the car paint for a long time. For the weather resistance stability of car clothing, the following test methods are usually used:

 

High and low temperature environment testing
UV accelerated aging test
UV yellowing resistance test
Accelerated Hydrolysis Test

 

Through these tests, we can avoid serious gloss loss, cracking, hydrolysis, yellowing and other phenomena in the car clothing during long-term use, which will affect the service life of the car clothing and even endanger the safety of the car paint.

 

5. Glue performance test

 

Invisible car clothing is adhered to the paint surface through glue. The performance of the glue will directly affect the construction effect and service life of the car clothing. In order to ensure the performance of the glue, the following testing methods are usually used:

 

Ring initial bond test

Hanging stick test

Peel strength test

 

Through the above items, you can test the ease of installation of the car clothing, the adhesion effect, and whether the corners are prone to warping, so as to ensure the good glue performance of the car clothing.

 

6. Car clothing gloss test

 

 

Invisible car clothing has the effect of brightening the gloss of car paint, which mainly depends on the permeability and mirror reflection ability of the car clothing. Therefore, the following tests are often performed on car clothing:

 

High Gloss Transparency Gloss Test

Fixed blackboard gloss test

Visible light transmittance test

 

Through the above tests, the effect of invisible car clothing on improving the gloss of the paint surface and whether it will cause color distortion of the paint surface can be measured to ensure the beauty of the paint surface after installation.

 

7. Real vehicle mounting test

 

 

Through actual car installation, we can make clear and intuitive judgments on the ductility, construction difficulty, edge closing effect, and whether glue marks, offset printing, etc. are prone to occur on the invisible car cover, ensuring the quality of the car cover from the perspective of the installation operation.

In addition to the above core test items, many brands will also test the scratch repair rate, UV blocking rate, etc. of the car clothing, and regularly conduct sampling tests on different batches of products. Only such comprehensive and rigorous testing can truly ensure that consumers will buy them. Have peace of mind and use it with confidence!
