What are the characteristics of high-grade quartz stone?
Between the resin content of quartz stone quality is 7-8%, packing uses the natural quartz crystal minerals, the SiO2 content is more than 99.9%, and in the manufacturing process to purify, any radiation may lead to heavy metal impurities in the raw materials do not contain color, were prepared by using high-grade or imported pigment. Its performance is non-toxic, good processing, is not easy to break and deformation, not bleeding, yellowing, visual color pure, stable quality, uniform color, texture fine particles, feel good, good anti UV properties. Manufacturers have a certain scale, good market reputation and perfect service system, products have security signs, maintenance manuals and product certification.
What are the characteristics of low-grade quartz stone?
Quartz stone low resin content more than 12%, the production process and common artificial stone, artificial casting, manual polishing, filler used commonly used glass fragments, or add inferior quartz with calcium carbonate, were prepared by using low-grade domestic color pigments, its performance is easy to scratch, surface breaking and deformation, seepage, color change Huang, the quality is not stable, uneven color, poor feeling, no resistance to ultraviolet. Small manufacturers, confusion in the market.
How to identify the merits of quartz stone?
A look: visual products pure color, the surface is similar to plastic resin feeling, the front of the plate without stoma.
Two smell: nose smell without pungent chemical smell.
Three touch: touch the surface of the sample, silk feeling, no astringent feeling, no obvious sense of injustice.
Four strokes: with iron or quartz stone board surface, without obvious scratches.
Five touch: the same two pieces of percussion each other, not easily broken.
The six measure: its anti pollution performance, take a piece of material, 200*200 size can, on the surface of the sheet on a few drops of soy sauce or red wine, 24 hours after washing with water, no stain.
Seven, burning: take a piece of artificial stone, slender small strip, placed on the fire burning, poor quality quartz stone easy to burn, the quality of the quartz stone is not burning, unless coupled with combustion supporting things, and will automatically extinguish.
Eight check: check whether the product quality system certification, quality inspection reports, security signs and so on.
