pebbles filter

As a natural pebble stone, taken from the earth's crust millions of years ago experienced after exercise by the ancient riverbed sand and gravel produced by the mountain uplift, experiencing the impact of flash floods, water removal process of continuous extrusion, friction. Tens of thousands of years of vicissitudes in the course of evolution, they have swallowed the movement of water will hit the waves, the collision was gravel friction loss irregular edges and corners, and they are deeply buried sediment a silence of millions of years. Cobblestone main chemical ingredient is silica, followed by a small amount of iron oxide and traces of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as those for the iron crimson and blue were the copper and purple are manganese, silicon dioxide colloidal yellow translucent stone for the pulp, with emerald green mineral, etc.; these ions dissolved dioxide pigment hydrothermal silica content in different types and, thus showing a bias, changing color depth, so showing a black pebble, white, yellow, red, dark green, schungite other colors.
    The use of pebbles: pebble is widely used in public buildings, villas, garden buildings, paved roads, parks rockery, bonsai filling materials, garden art, and other advanced superstructure. It carry forward the ancient oriental culture, but also reflects the Western classical, elegant, a return to basics style.
    Pebbles also water, sewage, electricity, garden items such project provides high-quality materials. Also ceramics, precision casting, papermaking, abrasion, chemical, silicon, to provide national defense and other raw materials.
    Cobblestone derivatives: cobblestone products: a mechanism of natural color pebbles, river pebbles, stone, dry stick stone, stencilled stone, landscaping stone, petrified wood, culture stone, natural color marble meters and other decorative materials and interior decoration Senior stained with sand, non-toxic, tasteless, non-bleaching. Quality of hard, sharp color simple, with compression, corrosion resistant properties of natural stone, is an ideal green building materials.
    Pebbles is a different filter in the filter are necessary cushion filter, I have a natural plant-based cobblestone filter (was oblong-shaped variegated) and mechanical processing cobblestone filter (close to spherical, pink and white) stone Quality hard, compression wear, is the best cushion filter material, packing density of 1.85 t / m3, Mohs hardness 7.5, hydrochloric acid soluble rate of ≤ 3.5%. 
   

 

Pebble

The main chemical composition is silicon dioxide, followed by a small amount of iron oxide and traces of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as those for the iron crimson and blue were the copper and purple are manganese, silicon dioxide colloidal yellow translucent stone for the pulp, with emerald green mineral, etc.; these ions dissolved dioxide pigment hydrothermal silica content in different types and, thus showing a bias, changing color depth, so showing a black pebble, white, yellow, red, dark green, schungite other colors.

Use
Pebbles are widely used in public buildings, villas, garden buildings, paved roads, parks rockery, bonsai filling materials, garden art, and other high-level superstructure. It carry forward the ancient oriental culture, but also reflects the Western classical, elegant, a return to basics style.
Pebbles also water, sewage, electricity, garden items such project provides high-quality materials. Also ceramics, precision casting, papermaking, abrasion, chemical, silicon, to provide national defense and other raw materials.
Nanjing stone of the physical parameters: Material: 95% of silicon dioxide (SiO2).
Performance parameters: surface finish 98%, compressive strength at 600 Kg/M2 more.
Cobblestone standard transformers
Ministry of Construction ministerial standards required, the lower part of a large oil-filled transformers should have oil storage tanks, an area of ​​flat to slightly larger share of the transformer, the depth of 1M or so, diameter 5-10CM laying around pebbles, the main purpose is to absorb the transformer oil spills.
Standards:
Typical fire power equipment order DL5027-1993 in 7.3.4 provides for 50-80mm.
"3-110KV high-voltage power distribution equipment design specifications" (GB 50060-92) Section 5.4.5 of the laying of oil storage tanks should be not less than 250mm thick layer of pebbles, the pebbles in diameter should be for the 50-80mm.
