كيف تحكم على جودة منتج GRC؟ شرح مفصل لمعايير تقييم جودة المنتجات

Judging the quality of GRC products requires professional knowledge and scientific methods. This article introduces how to accurately assess GRC product quality from multiple dimensions, helping you make the right judgment.

First, observe the product's appearance quality. High-quality GRC products have flat surfaces, uniform color, and neat edges. A crisp sound when tapped indicates good density. Measure dimensional deviations—qualified products should have a length deviation within ±2mm. Qinglong products use advanced production processes with dimensional accuracy of ±1mm, far exceeding industry standards. In terms of strength performance, flexural strength is a key indicator; high-quality products should reach ≥18MPa. Qinglong products achieve measured values of 20-25MPa, exceeding standard requirements. This high-strength performance was verified in the Wuhan Han Show Theater project.

Key Points for Appearance Quality Assessment

The surface should be free of cracks, chipped corners, and stains. Color should be uniform and consistent, with no color variation. Edges should be neat, without burrs. These appearance indicators reflect the level of production craftsmanship.

Dimensional Accuracy Testing Methods

Use tools such as calipers and levels to measure dimensional deviations. Length deviation ±2mm, diagonal deviation ±3mm. Qinglong products achieve an accuracy of ±1mm, demonstrating high-precision production capability.

Strength Performance Testing Standards

Conduct flexural strength testing in accordance with the JC/T940 standard. High-quality products should have a strength of ≥18MPa with a coefficient of variation ≤10%. Qinglong products achieve a strength of 20-25MPa with a coefficient of variation ≤5%.

Durability Performance Evaluation Indicators

Observe the water absorption rate through water immersion tests; high-quality products should have an absorption rate below 10%. Frost resistance should withstand 25 freeze-thaw cycles without damage. These indicators reflect product durability.

It is recommended to commission a third-party testing agency for testing to obtain objective data. Choose high-quality products to ensure project quality.
