Product Name: COBBLESTONE

Pebble can be divided into many kinds according to their appearance and shape, there are polished and sub - light pebble. Pebbles have many kinds of color, it is natural form resembles a goose egg shaped rock, smooth surface, cement and poor bonding, mixing of concrete mixture liquidity is better, but after hardening of the concrete strength is lower. The quality is hard, the color is bright and simple, has the compression, the wear-resisting corrosion resistant natural stone characteristic, is one kind of ideal green building material.
The pebble is widely used in a variety of mechanical filters ideal cushion filter in the supporting layer. Pebble is the bottom layer; quartz sand filtering layer, fluffy cotton is adsorbed layer! Role is an initial filter, deep bed filtration, purification and adsorption. Suitable for all kinds of filter. The water chestnut like appearance, surface area, high mechanical strength, no impurities. Pebble from the color, texture up to distinguish, the best quartz pebbles, better than some areas of weathered stone better than the time of the wind will be broken for a long time. Interior decoration on the selection of Yuhua stone; paving, gardens, transformer cobblestone chosen general quartz pebbles.

As the water purification material of gravel, foiling layer of prayer, we in the traditional water purifier can also see the pebble foil layer is introduced, but as the use of water purification materials have certain specifications, to reach this standard can be used as a water purifying material.
Use of pebbles:
1, construction, the use of the stone in a number of European style buildings and parks. A lot of people in the yard can see the pebbles, pebbles paving use can increase the aesthetic feeling of the building.
2, garden, pebbles can purify the water, there is a certain role in the sewage. So in some of the gardens where there is water flow, the pebble is used as a filter.
3, health care, massage can be made of pebbles. A lot of people use cobble massage shoe soles massaged, pebbles can activate collaterals, have certain effect of invigorate the circulation of blood, for the elderly can prolong life.
4. Application in public buildings, villas, courtyards, laying roads, parks, rockery, bonsai filling material, garden art and other senior superstructure.
5 for water purification, sewage treatment, power, garden and other projects to provide quality materials. Also for ceramics, precision casting, paper, abrasive, chemical, silicon, defense and other raw materials to provide.
6. It is widely used in power transformers using, water treatment filter cushion, public buildings, villas, garden, garden road laying, river levee, lake, chemical plant, sewage treatment plant, steel mills, water plants and other engineering is preferred excellent material.
Natural pebbles are through the baptism of nature, compared with pure natural, texture is relatively cold. Natural pebbles in the ground after thousands of years of friction and washing, is more valuable. Synthetic pebbles prices relatively low, synthetic is mainly through polishing treatment is carried out on some of the stones, artificial synthesis of cobblestone texture will have the feeling of resin, not cold, so the price is lower. Now we see most of the pebbles are used for the synthesis of artificial cobble stone.
