Recently, the Science and Technology Department of the Ministry of Science and Technology and the Department of Condition and Finance organized relevant experts to conduct project task acceptance and project financial acceptance of the “Eleventh Five-Year†National Science and Technology Support Program “Occupational Hazard Prevention Key Technology and Equipment Research†in Beijing. By reviewing the relevant materials, listening to the project team's report, and based on the inquiry and discussion, the acceptance expert group unanimously agreed to pass the project finance and project task acceptance.
Vitrified Grinding Wheels mean grinding
wheels in ceramic bonded. Vitrified grinding wheels can be superabrasive
grinding wheels like diamond grinding wheel or CBN Grinding Wheels. It also can
be abrasive grinding wheels such as white aluminum oxide grinding wheel,pink
grinding wheel,silicon carbide grinding.
Vitrified grinding wheel is only one type
of bond, which is ceramic, it can be in any type of abrasive.
The main ingredient of vitrified bond
are vitreous material with low melting point, such as borosilicate glass, lead
glass, etc.It is widely used in various grinding methods such as outer
circle, inner circle, flat surface, centerless, etc. It is the most commonly
used bonding agent for abrasive tools.
Vitrified bond is characterized by
high chemical stability, almost can work in a variety of cooling media,
small elastic deformation, brittle, can be made into a variety of hardness
levels of grinding tools to adapt to the processing of various hardness of the
workpiece. Vitrified bond has good self-sharpening.
The grinding efficiency of single crystal
diamond with vitrified bond grinding wheel is higher than metal bond
grinding wheel. The wear ratio is very small and the processing cost is
low. Therefore, the grinding efficiency of single crystal diamond with ceramic
bond grinding wheel can be greatly improved.

In view of the severe situation faced by occupational hazards in China, this project has studied the classification methods of high-risk occupational hazards, the monitoring and early warning index system and early warning model of occupational hazards, the comprehensive statistical evaluation methods and index system of occupational hazards in workplaces, the impact of dust on the organism and the comprehensive prevention and control strategies. Emergency response plan for sudden occupational poisoning accidents; establishment of laboratory testing system for dustproof and anti-toxic respiratory protection products, special operation sites and enterprise occupational hazard evaluation grading standard system; development of high-efficiency, low-resistance graded filter materials preparation process and filtration Materials, corporate occupational hazard assessment and risk grading software. The research results of the project will play an important role in supporting the prevention and control of occupational hazards in China.
The Ministry of Science and Technology, the Department of Science and Technology, the Department of Finance, the 21st Century Center, the Ministry of Planning, Science and Technology, the Ministry of Planning and Technology, and other responsible comrades, as well as the main research staff of the project team attended the meeting.
