Yunnan strengthens the security construction of primary and middle school kindergartens to delineate safe areas around the school

In order to prevent campus safety accidents, the General Office of the Yunnan Provincial Government recently issued the “Implementation Opinions on Strengthening the Construction of Safety Risk Prevention and Control System for Kindergartens in Primary and Secondary Schools” (hereinafter referred to as the “Opinions”), which clearly sets the requirements for campus safety according to the law. Protected areas, 100-1000 schools, with at least 2 full-time security guards; prevention and control of school bullying.

Equipped with full-time security guard
Promote the use of intelligent systems such as face recognition
The "Opinions" require that governments at all levels should provide special and part-time security and security for schools. Schools with a total number of teachers and students of less than 100 will be equipped with at least one full-time security guard; schools with 100-1000 students will be equipped with at least two full-time security guards; for schools with more than 1,000 students, one additional full-time security will be added for each additional 500 students. member. There are at least 2 full-time security guards in boarding schools, and one additional security guard for each additional 300 boarders.
At the same time, the school should strengthen communication and contact with the community (village committee), establish a school safety and security volunteer team composed of parents, police security guards, and duty teachers to maintain the order of the school and the school gate during the school hours. Transfer students to key and dangerous sections. Boarding schools should be equipped with dormitory management staff as needed, and female dormitory must be equipped with female accommodation managers.
In terms of the construction of a safe campus, the Opinions require the promotion of intelligent systems such as face recognition and visitor registration, such as teaching buildings, dormitory buildings, corridors, canteen operations, catering rooms, sample rooms and storage rooms. A video image acquisition device is installed in an important area, and a perimeter alarm device and a one-button alarm system are required to be installed.
Set up student help phone
Severe punishment, repeated education, no change, repeated violence
In order to prevent and control student bullying and violence, the Opinions pointed out that a long-term mechanism for preventing and controlling student bullying and violence should be established. Schools must effectively fulfill their education and management responsibilities, set up student calls and contacts, early detection, timely intervention and suppression of bullying and violence, strengthen students' ideological and moral education, rule of law education and mental health education, and improve the school bullying incident plan and disposal process. . For students with bad behavior or violent behaviors, if the circumstances are minor, the school will carry out criticism and education; if the circumstances are serious, explore and establish a system of training by the police. Students who repeatedly fail to change their education and repeatedly commit bullying or violence shall be dealt with according to the law. Acting on the outside school to educate, coerce, deceive, and use the crimes committed by primary and secondary school students in schools to crack down and punish according to law.
Security protection area around the campus
Resolutely ban illegal transportation of students and child vehicles
In the surrounding areas of the school, according to the plan, the campus security protection area shall be determined according to the law. In this area, enterprises and facilities that prohibit new pollution to the environment shall be prohibited according to the law. It is forbidden to set up stalls for mobile food vendors and prohibit the establishment of Internet service, entertainment, lottery franchise, etc. It is forbidden to set up places where there are potential safety hazards.
Reasonable installation of warning signs, deceleration shackles, belts, fences and other facilities around the campus, resolutely ban illegal transportation of students and children's vehicles, timely stop all kinds of traffic violations, and ensure that the security around the campus in key locations and key periods Controllable state. Areas with conditions should actively explore the establishment of “transportation harbors” and stop-and-go passages at the school gates.
During the school, students will implement closed management on the campus, and set up hard anti-collision facilities at the school gate according to the conditions to prevent people, vehicles and other illegal entry into the campus.
School bullying violence
Seriously pursue the responsibility of the responsible person
Our province will severely crack down on illegal and criminal activities involving school and student safety. In the event of a safety accident causing injury or death to teachers and students, the relevant department shall determine the nature and responsibilities of the accident according to law. If the school and relevant parties have responsibilities, it shall be held accountable for the responsibility of the responsible person; if the school has no responsibility, it shall clarify the facts and explain in time. In the event of a major accident or death such as campus fire, crowded trampling, infectious diseases, food poisoning, or school bullying, violence, sexual assault, etc., it is necessary to seriously investigate the responsibility of the responsible person. To study and establish a "school-speaking" prevention and treatment linkage system, the public security organs must promptly and resolutely crack down and punish the "school-speaking" behaviors such as encircling the campus, beating insulting teachers, and fighting school property, and ensuring the normal education and teaching order of the school.

Pyrite as Fillers Used in Grinding Wheels/ Abrasive Tools

Ablation grinding wheel / abrasive( filling agent )

PYRITE__As fillers used in grinding wheels/ abrasive tools

 

Place of Origin: Henan Luoyang, China

Pyrite, Iron pyrites, pyrites lump, Ferro sulphur, Pyrites powder.

Product Description

Detailed introduction:  is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.

Formation of a protective layer 
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.

4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2 
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2 

400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.

FeS2→FeS + S 
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).

(4)Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:
