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.

First, we must establish and implement a 'block-based, block-based' responsibility system, which complements the government’s leadership responsibilities with the supervision responsibilities of the department, and forms a unified pattern of leadership at all levels of government, close coordination among departments, and implementation of comprehensive governance.
It is necessary to further improve the work system for investigating major cases and cases. Strictly implement the reporting system for investigating major cases and cases, and establish a linkage mechanism for major cross-regional cases to ensure thorough examination of major cases and cases.
It is necessary to establish a market access and withdrawal mechanism and firmly prohibit the production of production licenses that do not meet the conditions for production of fertilizers, and resolutely ban long-term, repeated production of fake and shoddy products or serious violations of the law. Institutionalization of access and withdrawal ensures that fake and shoddy products cannot survive.
It is necessary to establish a classification and supervision mechanism that will help companies in the intermediate level to change in the right direction. According to a certain standard, enterprises are divided into threes and sixs and so on. Those enterprises that are poor must be strictly monitored. The outlaws will be banned and no one can be left behind. For good companies to give some visible and supportive measures to promote all companies to do a good job.
An early warning mechanism must be established to prevent serious quality problems. It is necessary to be able to identify the signs of problems in a timely manner, but also be able to solve them in the bud in a timely manner after discovering the signs. Should there be problems, there must be an emergency solution to minimize losses within the minimum range. One is to organize a group of good companies to serve as product quality monitors; the second is to train informants and strive to build a full-fledged, prompt reporting network; third is the counterfeiting of agricultural materials to the countryside, to make post-event treatment into precautions.
The reporter learned from the national chemical fertilizers regional rectification work held on November 23 and Lincui County established a national high-quality chemical fertilizer production base experience exchange meeting was informed that AQSIQ proposed to establish and implement pre-prevention from counterfeit and shoddy, to the company’s Effective supervision, and then to the problem of how to deal with the five long-term mechanism to effectively solve the rebound of counterfeit agricultural materials.
