Hollow boards are increasingly used in daily life, and a large number of substandard products have emerged on the market. Therefore, when purchasing hollow boards, we should not simply pursue low prices and ignore the key factors of selection. Measuring the quality of hollow boards involves multiple standards, mainly including key attributes such as color, hygiene, safety, service life, curvature, load-bearing capacity, and flexural strength.
A simple and effective way is to check the certification of the hollow board. Before purchasing, check online whether the manufacturer of the product has obtained SGS environmental certification (with a 3C certificate and the certificate is valid). Such an inquiry can ensure that the purchased hollow board meets safety and environmental protection requirements.
When choosing hollow boards, you can follow the following simple and effective methods to ensure quality:
Appearance inspection:
Observe whether the color is pure. High-quality hollow boards are bright and shiny, with a clean and translucent surface without impurities or black spots.
Check whether the surface is flat and smooth, without torn edges, sand spots or unevenness.
Look at the cross-section of the board. High-quality products usually have better color and uniform structure.
Hand feel test:
Touch the board with your hand. High-quality hollow boards feel smooth, without graininess, and have uniform thickness.
Strength and toughness:
Gently press or bend the edge of the board. High-quality hollow boards are not easy to dent, and have good toughness and are not easy to tear.
Certification and logo:
Check whether the product has SGS environmental protection certification and ISO quality system certification to ensure that the product meets environmental protection and quality standards.
Weight and density:
Depending on the different thicknesses, hollow boards have corresponding density standards, such as 2mm density is about 300g/㎡, and so on. Heavier boards usually mean better load-bearing capacity and material density.
Applicability considerations:
Choose the appropriate thickness (commonly 3mm to 7mm) according to the usage scenario, and whether anti-static, conductive or flame retardant functions are required.
Trial and testing:
If possible, ask the manufacturer to provide samples for actual testing or small-scale trials.
For large-volume purchases, consider sending samples to a third-party testing agency for comprehensive testing.
Through these basic steps, even without professional knowledge, you can largely screen out hollow boards with reliable quality.
