Whether the birth of any new product can be fully rolled out in the market depends on the advanced nature of the product and whether it conforms to the national industrial policy. It has incomparable superiority over the old products.

1. The environmentally-friendly wave tile is an energy-saving roofing material that is formed by glass-magnesium inorganic materials, crop straws (straw, corn straw, cotton straw, wheat straw, etc.) under normal conditions. It is asbestos tile, glass steel tile, cement. The ideal replacement for tile and color steel tile.

According to the statistics released by the National Bureau of Statistics, the annual investment in real estate development in China is as high as one trillion yuan. The rapid growth of real estate investment and consumption has brought huge development space for the building materials industry. The annual consumption of asbestos tile and iron tile in domestic counties and cities is more than 500,000 pieces, and the annual consumption of provincial capitals reaches tens of millions. In addition, the problem of waterproofing and heat insulation of the top floor of the building has not been completely solved, so the “flat-to-slope” has been vigorously promoted and applied, which has brought unlimited business opportunities to the tile industry. At present, the roofing materials used in the “flat to slope” promoted nationwide must have the characteristics of light weight, rich and colorful colors, good waterproof performance, simple construction and moderate price. According to the figures released by the Shanghai Housing Development Bureau, Shanghai has started the “flat-to-slope” project since 2003. The annual renovation of roofing materials covers an area of ​​more than 3 million square meters, while Beijing, Tianjin, Nanjing, Hangzhou, Wuhan and other major cities. The “Ping to Slope” project has also been launched. In the next few years, the “Ping to Slope” project will provide a huge market space for roofing light decorative materials. The market share of new wall materials will also increase rapidly with an average annual growth rate of 8%. The future development of new wall materials is infinitely broad.

Second, the characteristics of environmentally friendly wave tile production line

The environmentally-friendly wave tile production line adopts the reverse synchronous operation process, with high automation, low labor intensity, simple operation, stable operation of the equipment, no noise, no pollution, adjustable product specifications and multi-purpose.

Third, product features

1. Lightweight insulation, sound insulation, fireproof and waterproof.

2, does not contain organic volatiles, is a green building material

3, installation, construction is convenient, can be bonded with a variety of materials, and can be processed well, can be nailed, saw.

Fourth, the color is rich, bright as a mirror, acid, alkali, pollution-resistant, and does not fade.

Five, product performance

Performance standard test value

Horizontal bending resistance 7/3000N/M 4900N/M

Longitudinal bending resistance 7/200N/M 320N/M

Anti-impact force shall not cause cracking or spalling

Water absorption 26% 14%

After impervious immersion, the tile body is not covered with ecchymoses.

Frost resistance must not have a layering phenomenon after 25 freeze-thaw cycles

Artificial chalking grade

Climate aging change level ≤ 2

Climate aging color difference E≤3 0.66

The special additive for thermal insulation board adopts the international advanced technology of combination of plugging and blocking. After adding slurry, it can react with magnesium oxychloride cement to release a large amount of gel material, block capillary channel and improve water resistance. At the same time, the additive can optimize the crystal structure, improve the lap state, and fundamentally solve the water resistance problem of the heat insulation board.

NSK Bearing

NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.

Single-Row Deep Groove Ball Bearings
Pressed Steel Cages
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.

Extra Small Ball Bearings and Miniature Ball Bearings
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:

Standard type
Flanged outer ring
Extended inner ring
Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
Maximum-Type Ball Bearings
Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 6200 and 6300 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.
