Does The Quartz Stone Slab Resist Crack?
Sep 06, 2021
Quartz stone has become an indispensable decorative stone for home decoration. Its scientific name is polymer composite material, also known as agglomerated stone, which belongs to artificial stone. It is made of 93% (not less than 90%) quartz crystal, 7% resin and other binders by manual die-casting. Because the content of quartz sand in the quartz stone slab is higher than 90%, it is called quartz stone.
The surface of the quartz stone slab is smooth, dense and non-porous. The density of the slab is 2.3-2.6g/m3 (15mm thickness), and the water absorption rate is almost zero. Therefore, the quartz stone has abrasion resistance, scratch resistance, high temperature resistance, anti-permeation, and anti-permeability. Performance such as bursting, which is what we often hear in the purchase. Today we will talk about the crack resistance of quartz stone.
People buy quartz stone because of its anti-crack property. Some sellers will also conduct small ball anti-crack experiments for buyers on site. However, why do we often have so many crack cases in our use? Although quartz stone has anti-crack properties, it does not mean that it will not crack.
Why does quartz stone crack? Because quartz stone is a brittle polymer composite material, it also has the characteristics of thermal expansion and contraction. It also has certain mechanical properties such as shrinkage stress, impact toughness, and elongation at break. When the material cannot withstand the internal cracking occurs when under stress and severe external impact. There are also man-made factors. Edge chipping occurred in the cutting of quartz stone processing, which caused small cracks in the plate to crack during use. When the quartz stone is installed, the expansion joints are not reserved, which can also cause cracks.
How to avoid crack in use? Note that the surface should not be locally heated for a long time, and should not be hit by heavy objects. No matter how good the quartz stone, it has its weaknesses, and only daily maintenance can extend its service life!
