Glasses frame is good or tungsten titanium steel plate is good or good
Tungsten carbon steel is good, but the price is more expensive The Internet will be more than 100 wide plastic steel profiles widely used, you can do plastic rails, steel doors, steel windows, etc., its wide range of uses. Insulation: multi - cavity structure design. Insulation, excellent insulation performance. Sound insulation: good sound insulation, even in the downtown area can also be quiet, so that home from noise interference. Corrosion resistance: steel profiles density, anti-aging. To adapt to the sun exposure, wet and other special places to use. Sealing: Multiple waterproof design makes the steel profile exceptionally airtight and watertight. Safety: steel profiles using insulating materials, high safety factor. Environmental protection: steel profiles can be recycled, in line with the basic requirements of future buildings. There are added under the Kazakhstan, steel is a space material, will not be deformed, it will not corrode, steel glasses can be more secure to protect the lens, 360 bending is not bad. This material is relatively high temperature, more than 230 degrees in the temperature will be dissolved; low temperature, minus 30 degrees will not break
One, steel glasses, evolved to a Chinese name, South Korea called tungsten titanium (ULTEM transliteration) glasses, also known as PEI (material referred to) glasses.
Plastic glasses, in 2017 in Korea and Japan has been popular, in July 2017, began to seize the Chinese mainland market.
Before October 2017, the domestic market is mainly South Korea's imports of plastic glasses, after October, the domestic began to have production, but because of the characteristics of the material, plastic glasses are high temperature and high pressure injection molding, the domestic injection molding process does not meet the requirements, resulting in Multi-bubble, easy to break, poor permeability. At the same time, the domestic color of plastic glasses for the spray up, so easy to fall off, off the skin, South Korea for the plating process.
At present, due to the proliferation of the concept of plastic glasses, the domestic shoddy, with other materials to act, most of them only have a real steel glasses light, and not with high-strength plastic, high toughness, no fade.
Domestic steel production and South Korea distinction: South Korea imports must be high-end, and now South Korea is also required under the Chinese market to do low-quality low-priced products)
Distinguish one: the basic domestic all are matte, can not do bright, South Korea imports most of the bright color, according to the needs of matte color;
Distinguish between two: the domestic color for the spray color, so it looks like a layer of leather package, South Korea for the plating process, tight adsorption, strong texture;
Distinguish between three: the domestic injection molding process is not reached, the permeability is not good, so all the spray color, do not do character, Korean production is transparent color, that is translucent color, crystal impurity
