Cost performance of quartz stone: Besides its material value,processing value,service value, healthy,environmently friendly,convenient to use(easy to clean,non-maintaining) and has rich colours.So consider from the cost performance,it is undoubtedly your wise choice. Scratch resistant quartz stone: Surface hardness of quartz stone is higher than general ironware,that means the ironware that family use is difficult to scratch and fret it.Please don't look down upon the issue of scratching,every scratch is the soil that bacterium survived on.No scratch not only mean esthetic,also healthy.So we propose good after-sale service is not as good as less after-sale service.It's the best product that no need to supply after-sale service. Antipollution quartz stone: Quartz stone contain many kinds of composite material and ultra little quartz powder which guaranteed the very high level structure without hole.That means there is basically no infiltration so long as clean the top to leave no liquid with the fresh water or neutral detergent after using it every time.Only need to clean the obstinate besmirch(such as tea stain) with cleanser and the besmirch will not permeate through material.The besmirch glued on the top and in the angle can also be removed with small shovel or steel wire ball,this is other material can't be born. Resistant to elevated temperatures quartz stone: The basic material for quartz stone is quartz crystal.Quartz is a high melting material(melting point is up to 1300 °C)which has quite high resisting of burning.It is the best material resisting high temperatures besides stainless steel on the market at present. Acidproof and alkaliproof quartz stone: The quartz stone is acidproof and alkaliproof,its resistance to corrosion is the best in existing top.The commenly used acid and alkali are not enough to destroy the top. aging-resistant quartz stone: High quality compound and aging-resistant additive which quartz stone included make it has very strong aging-resistance.We will not aware the aging of the material under normal temperature. Colorfast quartz stone: Most component of quartz stone are made up by man,but the pigment is mainly of mineral pigment which has very high colorfast capability.So it's difficult to find the change of colour by eyes unless put the quartz stone under strong sunshine for long time.It can basically be regarded as the colorfast material.
