The Shaanxi Heavy Vehicle Co., Ltd. 2012 Supplier Conference was held in Chengdu recently. It was learned from the meeting that Shaanxi Automobile's full-year production and sales volume for 2011 is expected to be the same as in 2010 and is expected to reach 100,000 units, which has become a benchmark for the domestic heavy truck industry. Sex business.
In 2011, China’s commercial vehicle market has experienced a decline in production and sales since April. Although production and sales rebounded after entering September, the shrinkage of the commercial vehicle market throughout the year was a foregone conclusion. Up to now, the domestic commercial truck heavy truck industry has dropped by more than 10%. It is expected that the industry's production and sales will decline by 13% to 15% in 2010 compared with 2010.
According to reports, Shaanxi Automobile will pay close attention to new energy vehicles, military vehicle and export vehicle markets in 2012, and strengthen the development of lighter vehicles. With the country’s macroeconomic uncertainties and sharp decline in the industry, it still holds production and sales of 120,000 vehicles. The goal of an increase of 20% will not be shaken.
In terms of supply chain management and development, Shaanxi Automobile put forward six opinions: 1. Strengthen strategic cooperation with suppliers; 2. Improve internal management of suppliers and reduce costs; 3. Promote the construction of large-scale and specialized supply chain systems; 4 , unite as one, hold group warm to realize common development; 5, increase personnel training, break through the bottleneck of supply chain management; 6, pay attention to the development of Shaanxi Automobile's supply chain, promote centralized procurement work.
Fluorocrystalline mica, also known as fluorphlogopite mica, synthetic mica, artificial mica, synthetic mica crystal, belongs to the silicate type artificial mica crystal, is under the high temperature condition of 1500°C, through strict process conditions and material ratio, in platinum The mica crystals smelted in the yttrium have a chemical formula of KMg3(AISi3O10)F2(OH)-, and do not contain (OH)-. The (OH)-hydroxyl group is replaced by F-(fluoro), which is similar to the fluorite mica. Materials commonly used in the general industry are natural mica. Natural mica is an underground ore naturally formed and belongs to the class of silicates. Most of the industrial mica used is phlogopite (brown) and muscovite. Its ideal chemical formula is KAI2(AISi3O10)(OH)2. OH)-(Hydroxy), due to the presence of hydroxyl (water molecules), its performance in all aspects is far lower than that of fluorocrystalline mica.
The main characteristics of fluoride crystal mica:
1, high temperature: can work long-term in the 1100 °C environment.
The testing department of the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences (nationally recognized testing institute) tested the thermal weight loss of 8% at 1100°C for 48 hours, and the melting and devitrification temperature was 1375°C.
2. Electrical insulation: The volume resistivity is 10 times higher than natural mica. Electrical breakdown strength is PTFE
Lean 10 times.
3, hot and cold blasting stability is very good

Inspection, all qualified.
4, anti-corrosion:
Fluorophlogopite does not react with acid and alkali solutions, and does not react with water. Under the long-term (2 to 3 years) scouring of high-temperature and high-pressure water (including acid and alkali), the original clarity and transparency can still be maintained.
5, high frequency performance:
The dielectric constant of fluorite mica is 4.6 ε, and the dielectric loss is (1~4)×10 −4 tg δ, and the dielectric loss is very low. And because of the pure texture, all parameters are extremely stable.
6, optical properties
Since the fluorite mica contains less impurities, its light transmittance is compared from infrared to ultraviolet.
High, the transmittance is close to 100%.
7, Mosaic (Mosaicity):
The Mosaicite of fluorocrystalline mica is less than 0.25 degrees, which was produced in the experiment.
The neutron flame is not high enough to absorb multi-band light beams and is an ideal neutron monochromator test material.
8, vacuum deflation performance:
The evaporative volume of fluorite mica is low, and it is measured with a mass spectrometer and the trace gas released is only
O2, N2, Ar and other adsorbed gases. Since the H2O vapor is not released, this is extremely valuable for use as an electrical vacuum insulation material, which can greatly increase the service life of the vacuum device.
9, excellent physical properties:
Fluorocrystalline mica has atomicity flatness, transparency, separability and elasticity, not aging
It is not brittle and so on.
Due to the high temperature resistance, corrosion resistance, low frequency loss, and high bulk resistivity
Absorb multi-band light beam, excellent light transmittance and other advantages. Therefore it has become an ideal new material in the high-end area.
Fluorocrystalline mica Available in:
In the range of 180mm×53mm or ∮76mm, it can be processed into various shapes according to user requirements. Thickness within the range of 0.02mm~1.0mm can be allocated according to user requirements. The conventional thickness is 0.04~0.2mm.
