Question 5: security technology in the public security work in the understanding of the role of China's security technology to prevent the rapid development of the cause of the community has aroused close attention. Due to the history and reality of the many conditions of the limitations of China's security technology to prevent the work of many theoretical and practical issues have not been able to get serious research and definition. This paper addresses some of the problems encountered in the actual work, puts forward some of the author's thinking and suggestions, and I hope to play a role in attracting jade. Inappropriate, welcome industry colleagues to criticize and correct.

First, the concept of security

Security is a historical category of concepts, it is first of all a natural choice for human survival, with the continuous development of productive forces and social and economic progress, its content, form and constantly changing, and gradually formed a specialized technology and the corresponding industry, an important part of social and economic life.

1. The general concept of security and prevention (Security& Protection)

According to the modern Chinese dictionary, the so-called security is no danger, no infringement, no accidents; the so-called prevention is to be prepared for, on guard, and preparedness refers to be ready to deal with the attack or to avoid being victimized, and the guard refers to the defense and protection.

Comprehensive explanation of the above, can we give the following definition of security precautions: preparedness and protection to cope with the attack or to avoid victimization, so that the protected object is in no danger, not subject to infringement, no accidents in a safe state.

Obviously, here, safety is the purpose, prevention is the means, through the means of prevention to achieve or realize the purpose of safety, is the basic connotation of safety prevention.

2. Two security explanations (Safety and Security)

The Chinese said safety, in English there are Safety and Security two explanations.

The main interpretation of the word Safety in the Modern Advanced English-Chinese Dictionary published by Oxford University is: safe, secure; insurance (lock), insurance (box), etc. The main interpretation of the word Security is: safe, secure; insurance (lock), insurance (box), etc. And the main explanation of the word Security is: safety, no danger, no worry; provide something safe, make something free from danger or worry; collateral, guarantee; safety (police), security (troops), etc.

In fact, the Chinese security is a broad security, which includes two meanings: one is the natural or quasi-natural attributes of security, which corresponds to the English Safety; and the other is the social and humanistic security, that is, security with obvious human attributes, which corresponds to Security. The destruction of natural or quasi-natural attributes of safety is not mainly due to the purposeful participation of human beings, such as natural disasters (floods, droughts, earthquakes, etc.) and quasi-natural disasters (product design defects, environmental and sanitary conditions deterioration, etc.) resulting in the destruction of safety. The destruction of social and human security is mainly due to the purposeful participation of human beings, such as invasion of theft, robbery, vandalism, explosions and other illegal and criminal activities resulting in the destruction of security. Therefore, broadly speaking, security should include Safety and Security two layers of meaning, and we often say that security is mainly narrowly defined security: Security, foreign usually called "security".

3. Loss Prevention and Crime Prevention - the essence of the connotation of security prevention

In the West, do not use the word "security prevention", but with loss prevention and crime prevention (Loss Prevention & Crime Prevention) this concept. Crime Prevention) this concept. Just as the Chinese words security and prevention are used together to form a new compound word, in the West, Loss Prevention and Crime Prevention are also used together. Loss Prevention and Crime Prevention constitute two aspects of the one issue of Safety/Security. Abroad, Loss Prevention usually refers to the focus of the social security industry, while Crime Prevention is the focus of police law enforcement. The organic combination of these two can ensure the stability and safety of the society. In this sense, Loss Prevention and Crime Prevention are the essence of security prevention.

In summary, security prevention is both a public security business (police enforcement departments), but also a social public **** business and socio-economic industries. Their development and progress, both dependent on the development and progress of science and technology, and at the same time for the progress and development of science and technology to provide the creation of a superior social environment.

4. Social public **** safety science and technology with Chinese characteristics

It should be noted that loss prevention (Loss Prevention) is still a relatively broad concept. Broadly speaking it includes disaster prevention and mitigation and ...... >>

Question 6: Security control boards, security circuit boards, pcb how to do three defense protection processing? Security control boards, security circuit boards, pcb to do the three anti-protection process, we have always been the use of Yongan electronic chemical production of circuit board moisture protection paint products, you can then assemble a good instrumentation circuit boards, the surface of the circuit board is brushed or sprayed with a layer of Yongan YA-630 circuit boards anti-Chuan paint, completely dry after a good water-repellent, high- and low-temperature resistant properties; its curing into a transparent layer of protective film, with superior insulating properties. Protective film, with superior insulation, moisture, anti-leakage, shock, dust, corrosion, mildew, anti-part loosening and insulation corona resistance, etc., recommended

Question 7: Several special operators need to be equipped with security supplies, seek professionals to give the specific name of the supplies, materials and other information. 20 points This question is very difficult for someone to answer all.

I have done enameled air work, the need for a set of safety belts, safety latches, emergency lanyards, helmets, three shoes. The workplace should also be prepared to high altitude rappelling rope and descender. It should be enough.

The rest is unknown.

Question 8: three-proof paint sprayed on the board to do the test, its adhesion can not meet the requirements, what is the reason, the board cleaned up. 10 points Mainly do the following points to check:

1, the condition of the paint. Such as whether the quality is qualified, whether it is stirred evenly, whether the fluidity is good, and so on.

2, air pressure. Such as whether the air pressure fluctuations, whether it contains too much water, and so on.

3, the nozzle. Whether there is localized clogging, whether the deformation, and so on.

4, environmental conditions. Whether there is the influence of wind blowing, and so on.

5, operation. Whether the operation is not in strict accordance with the regulations, and so on.

Analyzing product quality is nothing more than from the people, machines, materials, methods, environment five aspects.

I hope you can help.

Question 9: What measures should be taken by the warehouse security for the Spring Festival vacation Fire, theft, leakage prevention, three prevention.

To see if there is a hidden danger of fire

To see if the doors and windows are intact, there is no damage

To see if the goods are dripping, whether the pipeline is dripping

After that, there are some overall classes of checks and measures.

For example: whether the fire facilities are intact, smoke alarms, hydrants; whether the company is a unified power outage; whether the emergency contact book is complete; the rest is the seal of the paste
