Quartz stone, as one of the main materials for cabinet countertops, has a very high usage rate because of its high hardness and melting point, making it very durable. However, after long-term use, we usually find cracks on the quartz stone countertop. So, how to prevent the quartz stone countertop from breaking? Next, let's take a look with the editor of Fabulous Group.
1. When designing the opening position, the opening position should be greater than or equal to 80mm from the edge of the table to prevent cracking of the opening position. The corner of the opening position should maintain a radius of 25mm or more.
2. When installing the table top, there should be 2-4mm expansion gap between the table top and the wall to effectively ensure that the table top will not crack due to thermal expansion. The maximum distance between the countertop and the support frame or support plate should not exceed 600 mm to reduce deformation or even fracture of the countertop;
3. When designing the corner of the countertop, full consideration should be given to stress concentration, which may cause cracking at the corner of the countertop. Therefore, during processing, it is necessary to maintain a radius of 25mm or more at all corners.
4. In daily use, it is also necessary to avoid cracking caused by external factors, such as not hitting the quartz stone countertop with gravity, not directly touching extremely high temperature pots or utensils with the countertop, etc. A layer of insulation can be placed.
5. In the design of plane splicing, the physical properties of quartzite shall be taken into account to avoid the consequences of joint cracking caused by thermal expansion or stress concentration. When selecting the connection position, the force acting on the plate must be fully considered. Avoid connecting at corners or furnace entrances.
