No formaldehyde. Engineered quartz stone is composed of more than 90% natural quartz and about 10% color materials, resins, and other additives for adjusting bonding and curing. It is formed through negative pressure vacuum, heating and curing, and high-frequency vibration. The production process and raw materials do not contain formaldehyde components and production conditions, so there is no formaldehyde. In addition, the artificial quartz stone is hard in texture, compact in structure, and has the characteristics of wear resistance and pressure resistance, high-temperature resistance, corrosion resistance, and anti-permeability.

1. How to buy engineered quartz stone?
1). Determine the color of the pattern.
Under the conditions of sufficient light, place the selected slabs and the same batch of other marble slabs on the ground at the same time, and stand at a distance of 1.5m from them for careful visual inspection. It is required that the pattern tones of the same batch of marble slabs should be basically harmonized.

2). Check for surface defects.
Under the condition of sufficient light, place the plate flat on the ground, stand at a distance of 1.5m from the marble plate, and observe the invisible defects as no defects; whether there are cracks, sand holes, heterochromatic spots, stains, and depressions on the surface of the plate. At the same time, no missing edges or corners are allowed on the front of the board; no obvious traces are allowed on the front after bonding and repair, and the color should be close to the font color.

3). Check the mark.
The marking sequence of the marble slab is naming, classification, size, grade, standard. The naming sequence of the marble slab is the name of the place of origin of the block, the name of the pattern color feature, and the marble (codenamed M). The classification is based on the allowable deviation of the sheet size, the allowable limit tolerance of flatness, the allowable limit tolerance of the angle, the appearance quality, and the mirror glass.

2. How to choose quartz stone countertops?
1). When selecting quartz stone countertops, we should first observe the color of the quartz stone countertops. Under normal circumstances, it is recommended that you choose dark-colored quartz stone countertops to avoid staining problems after staining, such as black vinegar and soy sauce. Wait. Then look at the hardness of the quartz stone countertops. If the quartz stone is too brittle, it is not suitable for use as a countertop.

2). Look at the texture of quartz stone countertops. The texture of quartz stone used as countertops is generally monochromatic, and the pattern is simple. If the color of the quartz stone countertops is too bright and the patterns are too fancy, users will be dazzled after watching it for a long time. Then smell the taste, preferably quartz stone with a small taste and no pungent odor.

3). When buying a quartz stone countertop, you can use the key to gently scratch the surface of the quartz stone countertop to observe whether the countertop is scratched, and at the same time, observe whether there are pores on the back of the plate. Remember to ask the merchant for the maintenance method of the quartz stone countertop after purchase.
