Thread Rod
The galvanizing process is to coat the ordinary iron wire we see daily with a layer of zinc to extend the service life of the wire. Iron is very prone to corrosion and rusting, while zinc is a metal that is not prone to rusting. Plating zinc on the surface of iron through special equipment and processes can effectively resist corrosion and prevent rusting. Zinc has higher stability than iron and is also less prone to rusting in humid environments. Galvanized wire can be divided into two categories due to different production processes: hot plating and cold plating. Galvanized wire is widely used in various fields such as construction and packaging due to its good toughness and elasticity. Iron wire galvanizing equipment comes in handy during galvanizing.

Educational projector
It is well-known that the purchase amount of projectors in the education industry is about 60% of the entire industry, but for the education industry, the brightness, interaction and projection distance of the projector are its most important product characteristics, and the most important is that the brightness of the classroom environment may be compared. High, low lumen products can result in dimmed screens and blurred fonts, so when using high-brightness projectors, they can resist ambient light interference. In addition, the daily cost of users is the most important issue in the education industry. Traditional high-pressure mercury bulbs may only use 4000-5000 hours, but after the advent of 20,000-hour long-life laser projectors in 2012, it completely changed education. Industry life problems.
In addition, short-focus projectors and electronic whiteboards are interactive education methods that are constantly praised by the education industry. They can effectively interact with teachers and students so that students can absorb the teaching content more quickly.

Under the strong impact of DLP projection technology, the prices of home products of 3LCD projection technology are getting more and more close to the people. The rapid development of projection technology and the benign competition in the market promote the price reduction of projector products. It is absolutely necessary for users who need to purchase home projectors. It is a considerable buying temptation.
The 4K home projector is the biggest highlight of the 2012 home product. Although the 4K image quality is four times that of 1080P, the problem of source source will return to the same dilemma as 3D. According to statistics, the current domestic home projector sales of about 50,000 units, of which 1080P projectors account for about 40,000, 720P and WXGA is expected to sell more than 9000 units, while the market size of 4K projector is particularly dismal, about 1 About %, it is expected that sales will not exceed 100 units.
Micro Projector
Miniature projectors are the focus products of current projector products. After a short period of two or three years of development, they have evolved from dozens of lumens to 600 lumens, and have a service life of up to 30,000 hours. They also have built-in batteries. Users can project anywhere, anytime, and no longer be limited by power issues.
In addition, micro projectors are usually equipped with USB mobile memory direct reading function, users simply put pictures, music, movies or office software into the USB mobile memory, you can easily achieve direct projection display capabilities, and the compatibility is quite amazing. Commonly used file format projectors on the market can be demonstrated as always.

Family entertainment market will be the focus of development
At present, the Chinese projector market can be roughly divided into four parts: commercial, educational, popular entertainment, and home entertainment. Taking into account the huge potential demand of China's household consumption market, the home entertainment market will be the focus of China's projector market in the future. However, at this stage, factors such as low consumer acceptance and high product prices have yet to be resolved. As a new home appliance, projectors have a difficult way to go into the home. In particular, manufacturing companies have a relatively low degree of understanding of the characteristics of Chinese home projectors and consumer buying habits, making it more difficult for the market to dig. Home projectors are in the market introduction period, consumer awareness is low, and the market lacks guidance.
According to relevant industry research institutions, the current Chinese home projector market accounts for only about 3% of the total projection market share, compared with the level of Japan, Europe and other countries, is still in the lead-in period, there is a larger room for growth! China’s home video entertainment is still in the era of color TV. Although the projector is fully capable of replacing TV and providing viewers with a larger screen and higher picture enjoyment, the Chinese family’s traditional consumption habits have not yet been applied to home theaters. The projector fully accepts.
The projector has been regarded as a niche product and the market size is not large. There are many reasons for this, including the impact of LCD TVs and the consumption habits. In short, the growth of the home projection market has been very slow. To break the bottleneck of market size, it is imperative to expand the market segments, and to dig deeper into the market. Do it thoroughly. According to the situation in 2012, the sales volume of projectors in the country is about 2 million units, of which the number of home projectors is about 50,000 units. At present, the development of the projector market is reflected in several types: educational projectors, pico projectors, and home projectors. Industry analysts say that home projectors are the main direction for future development.
