When consumers choose kitchen countertops, The first thing the salesman recommends is quartz stone， Because quartz stone’s hardness is high, scratch resistant, and not easy to penetrate. It is a non-porous composite material manufactured under vacuum, high pressure, and high vibration conditions. Speaking of which, many consumers may have questions, is the quartz slab has no pores?
Pores in quartz stone are common, however, reducing the content of macropores and reducing the average pore size is beneficial to improving the permeability of quartz slabs. The size of the pore also has a name, less than 20nm is harmless. The permeability resistance of the product will not be affected; 20-50nm is less harmful pores, 50-100nm is harmful pores, and the more harmful pores are greater than 100nm, which has a relatively large impact on the permeability of quartz slabs.
In addition, quartz filling particle shape and pore size have a close relationship. The quartz slab made of quartz particles with high sphericity has low porosity and less content of large and super-large pores (>1000nm). This is mainly because the particles with high sphericity are packed tightly, and the structure of hardened resin sand is dense. Therefore, changing the particle morphology is conducive to improving the accumulation structure of quartz stone, reducing the harmful pores in quartz stone, and improving the hardness, density, permeability resistance, and other characteristics of quartz stone.
