Analysis of Hardness and wear Resistance of Keli Nai countertops
Hardness performance
Quantitative data support
The Mohs hardness of the Klinai countertop is 5-6. significantly higher than that of ordinary pig iron (4-5), and close to the hardness of human teeth (6-7). The hardness of some products can reach grade 6.8. and both the flexural strength and compressive strength can reach 360MPa, demonstrating high-strength physical properties.
Analysis of Material Properties
The Kelinai countertop is made of a composite formula of methyl methacrylate (MMA) and natural mineral aluminum trihydrate (ATH), with ATH accounting for 55%, which endows the material with a basis of high density and hardness. The addition of MMA enhances the toughness and processability of the material, forming a structure that combines rigidity and flexibility.
Wear resistance performance
Daily use verification
The countertop can withstand the direct cutting of food by knives without leaving any scratches. Daily operations such as cutting vegetables and cooking do not cause obvious damage to its surface. Even if there are minor scratches, they can be restored to smoothness through grinding, demonstrating excellent wear resistance.
Long-term usage effect
User feedback indicates that the Kelinai countertop can maintain a smooth surface without significant wear marks even after long-term and frequent use. Its wear resistance not only extends the service life but also reduces the risk of bacterial growth caused by surface damage.
The synergistic advantage of hardness and wear resistance
Double protection against impact and scratches
High hardness enables the countertop to withstand the impact of sharp objects, while good toughness avoids brittle fracture. This balanced characteristic enables it to perform exceptionally well in complex environments such as kitchens.
Maintenance cost reduction
The wear resistance reduces the frequency of countertop repair, and the impact resistance lowers the risk of accidental damage, comprehensively reducing the long-term usage cost.
Contrast and Limitations
The differences from quartz stone/rock plate
Compared with quartz stone and rock plates, the hardness of Kelinai countertops is slightly lower, but they have better bending performance. They can be processed by hot bending and are less likely to yellow or fade. This feature gives it an advantage in complex shape design.
Usage scenario limitations
Although it has a relatively high hardness, the Corine countertop still needs to avoid prolonged contact with high-temperature objects to prevent surface damage caused by thermal stress. In addition, it is relatively heavy, and when installing it, it is necessary to ensure that the supporting structure is stable.
