Exterior wall tiles are essential building materials for modern architectural decoration. The exterior wall tiles are diverse in style and have gradually extended to interior decoration to achieve a gender-resulting decorative effect. In order to meet consumers' various requirements for exterior wall tiles, the technology of exterior wall tiles is not only diverse, but also the types of exterior wall tiles are extremely rich. Next Xiaobian will introduce to you the types of exterior wall tiles . Facade tiles The surface of the bricks is not glazing, and the material and color of the front and back surfaces are the same, hence the name. Whole brick is a kind of wear-resistant brick, although there are varieties such as osmotic brick, but relatively speaking, its color is less than glazed tile. Generally less will be used for walls, most non-slip bricks are all bricks. Exterior tile type polished tiles The polished brick is a kind of bright brick that has been polished on the surface of the whole brick body. Polished bricks are a derivative of whole bricks. Relative to the rough surface of the brick, the surface of the polished tile is smooth. Hard and durable, suitable for use in most indoor spaces except the restroom, kitchen and indoor environment. Based on the application of the infiltration technology, the polished tiles can make various kinds of imitated stone and wood effect. Exterior wall tiles type of vitrified tiles Vitrified tiles are reinforced tiles. In addition to porcelain clay, they also contain a higher proportion of quartz sand components (the main raw material for making glass). These ceramic tiles have the texture of natural stone, but also have high brightness and high hardness. High wear-resistance, low water absorption, less color difference, and rich color, etc., are made by firing at high temperature, the texture is harder and more durable than the polished tile, and the finish is better. Mosaic of exterior wall tiles Mosaic is a kind of special brick, which generally consists of dozens of small bricks to form a relative big brick. Divided into ceramic mosaics, marble mosaics, glass mosaics. Exterior wall tile type split brick Splitting the brick production process requires splitting it into two pieces, hence the name Split Brick. This kind of exterior wall brick production process is more complicated. It is necessary to use raw materials made of ceramics to make wet mud and then produce it through professional techniques. Split bricks are divided into flat bricks and napped bricks, which are determined by the smoothness of the surface of the outer wall tiles, and their uses are different. Exterior wall tile type glazed tile Glazed tile is an exterior wall tile whose surface is burned glaze. Glazed outer wall tiles are made of clay and china clay. After firing, clay is red on the surface, and clay is off-white. The surface of the glazed outer wall tiles can be patterned. After the glaze firing, the wear resistance of the outer wall tiles is not very good. Pay attention to the usual maintenance.

Matters concerning the export of Graphite
Over the years, China has been the most * big exporter of Natural Graphite products, in deep processing of graphite products technology leading developed countries, is against the natural graphite "with purchase and adopt a generation of" strategy, and technology blockade, natural graphite as a kind of non-renewable resources, with very good foreground countries limit zhi, its export of primary products, such as export carbon rods, artificial graphite, Graphite Block, pre-baked anode, etc., need to be dealt with the dual-use items.
The price of natural Graphite Powder is determined by three main factors: carbon content, moisture and particle size distribution.
1. The higher the carbon content, the greater the purity of graphite, so the price will rise in the form of the acceleration line (i.e., the higher the purity, the more complex the production process, and the higher the price increases).
The larger the scale, the lower the natural content and the higher the price. Conversely, the smaller the particulate matter, the less content in nature and the higher the price. Therefore, for natural graphite, the price of the normal (i.e., the material at the top of the sieve) is high. In the positive eye, the smaller the number, the bigger the scale and the higher the price. In negative eyes, the larger the number, the smaller the scales, the higher the price, the lower the price of negative items.
Artificial graphite HS codes for 3801100090, customs supervision conditions for export license of dual-use items and technologies, when customs clearance in addition to submit normal trade documents, and shall be submitted to the ministry of commerce issued "export license of dual-use items and technologies".
Materials for application of electronic key for dual-use items:
1. Application of electronic key for approval and approval (seal of enterprise official seal and approval seal)
2. Copy of business license (seal of enterprise)
3. Photocopy of the record registration form of foreign trade operator or a copy of the approval certificate of the foreign-invested enterprise (with the official seal of the enterprise)
4. Applicant's identity card and copy of the company's legal person identity card (seal enterprise seal)
5. Service contract (please refer to the representative office or office)
6. Copy of bank payment receipt (wire transfer voucher, bill)
Information on import and export of dual-use items
1. Trade contract
2. Export (import) packing list
3. Certificate of final user and end-use abroad
Application for export license of sensitive items and technologies of the People's Republic of China, etc.
