The reporter recently learned that the Science and Technology Department of the Ministry of Industry and Information Technology has publicized the 485 industry standards. According to the industry standard revision plan, the relevant standardization technology organizations and other units have completed 485 items of electricity and machinery such as silicon carbide special products silicon oxide bonded silicon carbide board. And the revision and revision of ship, automobile, aviation and packaging industry standards. Among them, transformers, voltage regulators, solenoid valves for refrigeration, power converters, electronic modules for power tools, consumable tungsten-rhodium thermocouple wires, large-sized jaw-mounted electromagnetic clutches and many other standards are widely used in the power industry.

In order to further listen to the opinions of the community, before the approval of the 485 standards, the Ministry of Industry and Information Technology will publicize it, the deadline is February 2, 2013. Phone, email: KJBZ@miit.gov.cn.

Back Painted Glass

Back painted glass is any form of clear glass that is painted from the back side and viewed from the front side, or "first surface" side. Back painted glass is widely used for architectural spandrel glass, colored glass walls for interior glazing, colored glass back splashes, glass markerboards and dry erase boards, colored glass counter tops, shower walls, artistic glass, auto glass, marine glass, aero space glass, and more. Back painted glass is a modern alternative to other surfacing materials such as tiles and laminates in the world's decorative and architectural industries.


Our back painted glass color can be mixed on RAL Code or Parton Code, custom design, color size and qty., all make to order.
