The quality of carbon crystal plates can be judged from the following aspects:
1、 Appearance inspection
planeness
The surface of high-quality carbon crystal plates is smooth and flat, without obvious unevenness or waves. You can place the carbon crystal plate on a horizontal surface and observe its adhesion to the plane, or gently touch the surface with your hand to feel its flatness.
If the surface of the carbon crystal plate is uneven, it may affect the installation effect and aesthetics, and may also indicate problems with the production process, making it difficult to guarantee quality.

Color and texture
Observe whether the color of the carbon crystal plate is uniform and consistent, with no obvious color difference. High quality carbon crystal plates have bright and full colors, and will not fade or discolor.
Check if the texture is clear and natural, and if it matches the advertised sample or image. The clarity and naturalness of the texture can reflect the level of precision in the production process.

Edge processing
A good carbon crystal plate has neat and smooth edges, without burrs or cracks. Good edge treatment is not only aesthetically pleasing, but also reduces harm to the human body during installation and use. It also demonstrates the manufacturer’s attention to details and quality control.

2、 Performance testing
Hardness and strength
The hardness of carbon crystal plates can be tested using hardness testing tools such as hardness testers or simple methods such as gently scratching the surface with a key. High quality carbon crystal plates have high hardness and are not easily scratched or damaged.
When conducting strength testing, one can try bending the carbon crystal plate or applying a certain amount of pressure to observe whether it is prone to fracture or deformation. High strength carbon crystal plates can withstand certain external forces without damage and have a longer service life.

Waterproof and moisture-proof performance
Soak a small part of the carbon crystal plate in water for a period of time and observe whether it absorbs water, expands, deforms, or shows other damage phenomena. High quality carbon crystal panels have excellent waterproof and moisture-proof properties, and will not be damaged due to contact with moisture.
You can also check the relevant testing reports of the product to understand whether its waterproof and moisture-proof performance indicators meet the standards.

Fire resistance performance
Understand the fire rating of carbon crystal panels and check if the product has passed relevant fire testing and certification. High quality carbon crystal panels should have a certain degree of fire resistance, which can prevent the spread of fire to a certain extent and improve the safety of use.
You can use a lighter or other ignition source to approach the carbon crystal plate and observe whether it is easy to burn or produces harmful gases. But pay attention to safety and avoid causing fires.

Thermal insulation performance
If carbon crystal panels have insulation and heat preservation functions, their performance can be evaluated through professional testing equipment or comparative testing. Compare the carbon crystal plate with other materials and observe the temperature changes in the same environment to determine its insulation effect.
You can also view the technical parameters and specifications of the product to understand its insulation performance indicators.

3、 Brand and Certification

Brand reputation
Choosing carbon crystal plates from well-known brands usually ensures better quality. Famous brands often have stricter quality control systems, better after-sales service, and higher market reputation.
You can learn about the credibility of different brands through online searches, consulting with professionals, or referring to evaluations from other users.
Certification Mark
Check if the carbon crystal board has relevant certification marks, such as quality certification, environmental certification, fire certification, etc. These certification marks are important guarantees for product quality and performance.
Common certification marks include environmental protection mark certification, etc.

4、 Manufacturer’s strength and after-sales service
Manufacturer’s strength
Understand the scale, production equipment, technical level, and research and development capabilities of the manufacturer. Strong manufacturers are usually able to provide higher quality products and more stable quality.
Manufacturers’ strength can be evaluated by visiting them, checking their qualification certificates, and understanding their market share and industry status.

after-sale service
High quality after-sales service is also one of the important factors in judging the quality of carbon crystal plates. Good after-sales service includes product warranty, installation guidance, maintenance services, etc.
When purchasing carbon crystal plates, it is important to understand the manufacturer’s after-sales service policies and commitments to ensure timely support and assistance during use.
