5-8cm River pebble / bottom pebble production supplier for Zhoukou substation * *

contact person: Manager Zhang The stone materials are taken from the sand and stone mountains produced by the ancient river bed uplift after the crustal movement of tens of millions of years ago. They have experienced continuous collision and friction in the process of torrent impact and water transportation. In the course of tens of thousands of years of vicissitudes, they have experienced the movement of waves and water, and they have lost irregular edges and corners due to the collision and friction of gravel. The farther the water is transported, the better the quality of pebbles produced. The main chemical composition of pebbles is silica, followed by a small amount of iron oxide and trace elements and compounds such as manganese, copper, aluminum and magnesium. They have different pigments. Because of the different types and contents of these pigment ions dissolved into the silica hydrothermal solution, they present a variety of colors, such as black, white, yellow, red, dark green, cyan and so on.

The promotion and implementation of the above important and planning will play a guiding and supporting role in the development of the industry. In the past, our enterprises were small in scale, not rich in product lines, and relied more on upstream and downstream enterprises. This is also the reason for the obvious cyclical characteristics in the past, and the enterprise's revenue and profit fluctuated greatly under the influence of the economic cycle. Xuzhou Xinyi water treatment cushion series cobble filter material supplier: Pebble filter material, pebble (gravel) filter material, commonly known as pebble, pebble cushion, supporting layer filter material or cushion filter material, divided into (NATURAL) pebble and (mechanical processing) quartz gravel. Pebble filter material is made by natural river excavation, screening and water selection. It is spherical, pure white and variegated, and processed with machine-made pebble and quartz gravel. Pebble filter material.



Spherical cobblestone, is in a variety of variegated pebbles, with high hardness, green gray, spherical pebbles selected, and thenBall mill grinding for 40 hours to remove the surface impurities. The physical parameters of the spherulite produced by our factory: Material: more than 95% silica (SiO2); hardness: 7.5 mol; performance parameters: surface finish 98%, compressive strength above 600 kg / m2. Its technical parameters are better than those of cjt / 43-1999.



It also needs flowering and fruiting, and the young fruit begins to consume more nutrients. After the inflorescence is set and the fruit is as big as walnut, the top dressing can be done once or twice to ensure that the plant does not lose fertilizer; when the young fruit is fast, it is usually applied with 40% human manure or 5% sulfur-containing compound fertilizer leaching solution every 10 days in sunny days.

In short, the use of pebbles should be rich in variety, not limited to a pattern. In the construction, pebbles have unique aesthetic significance and application value, which can not only cost investment, but also achieve good landscape effect. The design customization of indoor outdoor landscape is more and more popular. The typical indoor waterscape is usually a small indoor waterscape, because water is the source of all things and the soul of the landscape. In the waterscape, with pebbles, it can simulate the natural appearance and endow the small scenery with life, which makes people have infinite Association. It can not only form a contrast with smooth tiles in texture, but also keep the water clean for a period of time, and give full play to its water permeability performance. Sewage treatment pebbles are mainly used for: construction, garden, pavement, landscape, chemical engineering, water treatment, lake bottom, etc. the surface of pebbles is smooth, flat and similar to the shape of a goose egg. The cobble material of sewage treatment: more than 95% silica; the smoothness is about 98%. As a kind of stone, sewage treatment pebbles are taken from the sand and stone mountains produced by the ancient river bed after the crustal movement tens of millions of years ago.
