High-speed development of China's Internet

Since 2008, China has become the world's largest network. By the end of December 2010, she continued to be the world's number one in terms of the number of Internet users of 457 million, broadband Internet users of 450 million, mobile Internet users of 303 million, and Internet penetration rate of 34.3%. People love the Internet and rely on the Internet because the Internet has strong advantages and qualities compared to traditional media. 1. The scope of dissemination is wider: she can be far ahead of traditional media in terms of distance and scope without being affected by country, region, weather and time and space; 2. Faster propagation: any event anywhere in the world, as long as Being placed online for the first time, it can be immediately noticed by people; 3. Information is more effective: people are actively acquiring the information they need on the Internet, and the powerful search function of the Internet, so the effective performance of the information is to some extent. Can be guaranteed; 4, the depth of information: the Internet can easily provide all the content that people want to know, and the information is more comprehensive. As a topic, we can see a lot of comments, both expert and netizens; 5. Interactivity and immediacy: The Internet makes information interaction possible, which facilitates immediate communication and communication between the two parties without barriers; A lot of information is available for free: the content of the web is very comprehensive, but the information is almost free, and of course there are a small amount of paid content, and most of these charges can also be obtained through free channels. 7, the lowest cost: the production of corporate websites, only domain name fees, hosting fees, website management staff labor costs. If a professional company is invited to design a website and maintain it, only the hosting fee, domain name fee, space fee and maintenance fee are lower. Li Yizhong, Minister of the Ministry of Industry and Information Technology of China, stressed that information technology should be turned into a “multiplier” for economic growth, a “transformer” for development, and a “booster” for industrial upgrading. In the first half of 2008, the number of Internet users and broadband Internet users in China exceeded the United States for the first time, ranking first in the world. At the end of 2008, China's Internet penetration rate reached 22.6%, surpassing the global average of 21.19% for the first time. In 2008, the number of Internet users in China reached 298 million, the number of broadband Internet users was 270 million, and the number of national CN domain names was 13.572 million. The three indicators continue to rank first in the world. Today's Internet has become a must for government offices, business management, workers' work, farmers' land, teachers' teaching, scientific research, student learning, and people's lives. Encountered the problem "checking the Internet" has become the habit and spoken language of netizens. Therefore, people are very concerned about the development of the Internet. The following "China Internet Development Statistics Table" is compiled by us according to the data in the China Internet Network Information Center (CNNIC) "The 22nd-27th China Internet Development Status Report" for reference.

Abrasive Lapping Film

Abrasive Lapping film is a type of polishing material used for fine abrasive finishing and polishing of surfaces. It is often employed in applications where a high degree of precision and surface quality is required. The key characteristics and applications of abrasive lapping film:

1. Composition: Abrasive Lapping film typically consists of a flexible backing material onto which abrasive particles are evenly coated. The abrasive particles can vary and may include materials like aluminum oxide, silicon carbide, diamond, cerium oxide, or other abrasives.

2. Manufacturing Process: The film is manufactured using advanced coating technology, ensuring a uniform distribution of abrasive particles on the backing material. The film may undergo high-precision cutting technology to achieve specific sizes and forms.

3. Grit Sizes: Similar to the Aluminum Lapping film mentioned earlier, abrasive lapping film comes in a range of grit sizes, from coarse to very fine. This allows for flexibility in addressing different levels of surface roughness and polishing requirements.

4. Particle Sizes: The particle sizes of the abrasive material on the film can vary, typically ranging from larger micron-sized particles to smaller nano-sized particles, depending on the desired level of abrasiveness.

5. Versatility: Abrasive lapping film is versatile and can be used on various materials, including metals, ceramics, plastics, and optical components. It is commonly utilized in precision machining, electronics, optics, and other industries where fine surface finishing is crucial.

6. Adhesive Backing: Some lapping film come with a Pressure Sensitive Adhesive (PSA) backing, allowing for easy attachment to lapping plates or other polishing equipment.

7. Applications:

   • Precision lapping and polishing of metal and ceramic parts.
   • Finishing of optical components, lenses, and mirrors.
   • Polishing of semiconductor wafers and electronic components.
   • Surface preparation for analysis and inspection.

8. Uniform Dispersion: Similar to other precision lapping films, uniform dispersion of abrasive particles is critical for achieving consistent results in surface finishing. This ensures that the abrasive action is evenly applied across the entire surface.

9. Customization: Like other lapping films, abrasive lapping films may be available in sheets, discs, or rolls, providing flexibility for different types of polishing equipment and applications. Customized products may also be available to meet specific customer needs.

Overall, abrasive lapping film is a valuable tool in industries where achieving a smooth and precise surface finish is essential. Its use is widespread in applications requiring fine polishing and finishing of various materials.
