How To Distinguish Best And Bad Quartz Stone Slabs?

Quartz stone slab is a new artificial stone synthesized by small quartz stones, which have a variety of colors, and the texture and luster of natural stone. And it is non-radioactive, reusable environmental protection materials, and green building interior decoration materials, so they are widely used in kitchen countertops, dishtops, kitchen and bathroom walls, tables, coffee tables, windowsills, door covers, and other fields.

Performance Of Real Quartz Stone

The glossy and bright surface of the quartz stone slabs is the result of more than 30 complex polishing processes; even after a long time of use, the surface is as bright as the newly installed table. The real quartz stone countertop has high hardness, corrosion resistance, high temperature resistance, and other characteristics, even with the use of a knife, shovel, or other sharp tools, the surface will not be scratched. It also has excellent corrosion resistance to the acid and alkali of the kitchen, and it also has high temperature resistance unparalleled by other artificial stone countertops.

In the quartz slabs, the higher the content of quartz, the lower the amount of resin, the better the quality, and the closer it is to nature, the more difficult it is to deform.

When the content of resin in quartz stone is greater than 10%, it cannot be called real quartz stone. In complex products, how to identify the quality of quartz stone slabs is particularly important.

Ideas Of Distinguish Best Quartz Stone Slabs

How to distinguish the best and bad quartz stone slabs, become a master of quartz products? We can test the products according to the characteristics of quartz stone.

Tip 1: Immersion Test With Hydrochloric Acid

In order to maximize profits, some manufacturers will adulterate calcium carbonate in the raw material of quartz stone slabs. And because of its calcium carbonate capacity and acid reaction, if you buy this kind of countertop, the surface is easy to change color after some time. Therefore, when purchasing, you can ask for a sample, put it in dilute hydrochloric acid or other acidic liquid. If the product contains calcium carbonate, it will react with the acid.

Tip 2: Seepage Test

The surface and internal structure of high-quality quartz stone slabs are also fine and uniform, so the water absorption rate is low and the permeability resistance is strong. If the production equipment and technology are backward, the manufactured quartz stones look the same, but the internal structure is loose and porous, with weak permeability resistance, high water absorption, and seepage. When purchasing, you can pour soy sauce on the quartz stone table to check whether it will leak color, Poor-quality ones will leak color in a day; high-quality ones will not.

Tip 3: Use A Knife To Check The Wear Resistance

The main composition of quartz stone plate is silica, which has the highest hardness, The quartz stone on the market is synthesized by quartz crystal and resin, and the quartz content is generally marked at about 93%. Therefore, the possibility of fracture is very small, and it is relatively wear-resistant. Fake quartz resin content is high, the surface hardness will be relatively low, and it is easy to scratch. When buying, you can use a knife to try to draw on the table.

Tip 4: Use Fire To Check Heat Resistance

If poor-quality quartz stone slabs resin content is too high, heat resistance performance will also be reduced. Therefore, depend on this, burn the sample with a lighter, and then see if there are traces left on it.

Characteristics Of Best Quality Quartz Stone Slabs

1. Hardness:

The surface Mohs hardness is 7, the simple detection method is to observe the damage point with iron point extrusion, there is no scratch.

2. High Temperature Resistance:

Can withstand heat of 300℃. Place a stainless steel cup filled with boiling water on the countertop for 30 minutes without discoloration. Or use a burning cigarette end on the quartz stone, does not change color.

3. Trademark

Identify the trademark on the front of the quartz stone.

4. Environmental Friendly:

It can provide green environmental protection certification tested by authoritative departments.

5. Fire Resistance:

Place a small quartz stone samples(like 10x10cm) on the fire, it can not burn.

7. Acid And Alkali Resistance:

Use 3% hydrochloric acid solution, 100g/L citric acid solution, 30g/L sodium hydroxide, or potassium hydroxide solution to erode the surface, the surface has no obvious changes.

8. Water Absorption:

If the water absorption rate is less than 0.04%, sprinkle a little water on the surface of the quartz stone after 24 hours to observe the color without white.
