How to purchase the right quartz stone for polishing quartz
countertop
Quartzite is an artificial stone made from broken glass and quartz
sand. The biggest advantage is wear resistance, no scratch, heat
resistance and no deformation. The table made of quartz stone plate
has higher toughness, stronger anti external crack force and longer
service life. Let's take a look at its buying skills.
1. Check wear resistance by knife stroke
The quartz stone mesa is mainly composed of silica, with the
highest hardness. The quartz stone on the market is synthesized by
quartz crystal and resin, and the content of quartz is about 93%.
Therefore, the possibility of fracture is very small, and it is
also wearable. The pseudo quartz has high resin content and low
surface hardness, so it is easy to scratch. The purchase, can use
the knife on the table and try to make sure.
2. Soak test with hydrochloric acid
In order to maximize profits, some manufacturers will be doped with
calcium carbonate on quartz quartzite raw materials. Calcium
carbonate and easily reacts with the acid, if you buy the table,
later used, it is easy to change the table. Therefore, when buying,
you can take a sample plate and put it in dilute hydrochloric acid
or other acid liquid. If the product contains calcium carbonate, it
will react with the acid.
3. Test infiltration
The surface and internal structure of high quality quartz stone
plate are also meticulous and uniform, so the water absorption rate
is low, and the permeability resistance is strong, but the backward
production equipment and technology are often limited to the
appearance, but the internal structure is loose and porous, the
anti permeability is weak, the water absorbability and
impermeability are strong. When buying, you can pour soy sauce on
quartz stone table to check whether it will color. The inferior
quartz stone surface will color for 1 days, but the high quality
will not.
4, High temperature test
Quartz stone, because of its own material characteristics,
determines its high temperature resistance, the temperature below
300 degrees Celsius will not have any effect on it, that is, no
deformation and fracture, poor quality of quartz stone resin
content is too high, heat resistance will also be reduced.
Therefore, we can use this point to burn samples with lighters and
see if there are any traces on them.
5. Compare the density
Good quality quartz stone has higher density and heavier weight. So
the same size quartz stone will be heavier.
