Analysis of the research process of protective clothing fire protection and anti-virus function test

Qinsun (Hong Kong) Co., Ltd. With the development of economic and social development, the fire has also changed the volume and quality. A fire destroyed dozens of fires, hundreds of life, hundreds of thousands, the fire of millions and even tens of millions of property is not uncommon. In particular, special types of malignant fire accidents are still more serious, 10 people die or die, and more than 20 fires have been seriously injured. The whole country has more than 10. Therefore, it is strengthened that labor protection for special types of workers should be made from the design and development and performance evaluation of protective clothing.

A few days ago, the project of "protective clothing multi-function design R D and performance evaluation" project completed by Donghua University, Shenzhen Youpintai Clothing Technology Co., Ltd. has obtained the second prize of 2013 "Textile Light" Science and Technology The project has made the multi-functional design R D and performance evaluation of protective clothing. The protective clothing has a variety of functions such as fire insulation, waterproof and ventilation, anti-drug antibacterial, suitable for an individual protection demand for emergency rescue for disaster emergencies.

A variety of hazards

It is understood that the general protective clothing is a flame-retardant protective clothing that uses essential flame retardant fiber processing. The nature flame retardant fiber represented by the among the aramid is naturally flame retardant due to its own special chemical structure. It is difficult to combust in the air. After the fire is removed, it will go out immediately, and the combustion is rapidly carbonized to form a heat insulating protective layer. Do not produce melting, drip or wear, can effectively reduce or avoid burns, this protective clothing protective function is single, comfortable and functional.

According to the leader of the project, Li Jun, director of the Director of the East China University of Clothing Design and Engineering. The protection model such as "layered insulation, multiple protection, functional assembly" is established, and a variety of harmful factors are implemented. The fabric system performance integrated design is performed using thermal protection performance TPP combined with total dissipation heat THL. At the same time, the two-step method is developed, constructs a composite fabric system composed of outer waterproof gas-free layers, insulating layers, and comfortable layers; uses aofoff fibrils to develop fire-resistant outer and insulating layers; development "three in one" Technology, the development of waterproof and breathable, anti-drug resistant and anti-gasification, anti-drug antibacterial selective osmotic fabric with "sandwich" structure; presence of four-dimensional stem structure design methods, and makes protective clothing type innovation design with homework activities.

"Fire" helps improve system

According to Li Jun, in the overall protection performance measurement level of fabric and clothing, the project has developed a variety of physical and chemical properties and comfortable errors in protective fabric systems. Characterization technology of performance, exploring the system and method for establishing system scientific protective clothing from fabric performance to overall performance evaluation of clothing. The project has revealed multi-layer weaving by developing the thermal protection performance testing device of the simulated microclobe fabric stretching shape.The evolution law of comprehensive performance of the material system; the research and development of high temperature liquid burns protection performance assessment equipment, which has obtained the theoretical research of the fabric and its clothing in high temperature liquid penetration protection. At the same time, the technical level of advanced firefield combustion fake people's clothing thermal protection performance evaluation system - "Donghua Fire" Objective evaluation of clothing, hot protection overall thermal protection performance.

It is understood that "Donghua Fire" is China's first burning fake person. In the high-risk environment in the fire, excellent protective equipment can effectively reduce the damage to firefighters and escapes. In the past, the fabric combustion experiment was generally used, but the experiment was unable to reflect the actual effect on the human body, it is easy to cause insufficient protection in use. Experiments with the combustion dummy simulate the fire environment, and better understand the effect of protective clothing. The "Donghua Fire" laboratory is the first firefield body body protection equipment combustion laboratory. At the same time, the dummy completely simulates the Chinese people's texture, and the high temperature heat flow can be accurately performed under different activity postures, and the degree of body skin burns is accurately reported. In addition, its joints can be adjusted to simulate the body activities of firefighters. This helps researchers according to the body characteristics of the Chinese, and can make further improvement in the part of the rescue activities, and the laboratory research team will then analyze the fake people after burning data. .

Hu Zu Ming, director of the Chemical Fiber Research Institute of Donghua University, said that the fabric development and combustion test, just as "the spear of each other". By demanding combustion testing of step-by-step upgrades, researchers will more scientifically design thermal protection equipment, effectively curbing dangerous environments such as fire, battlefield and thermal radiation to the human body.

The fastest way to use the fastest way

"Our project team adopts the responsible person system of the project, through the establishment of the sub-topic, determines the responsibility of the partnership, and makes the power and responsibility, the task is clear." Li Jun talking. In response to the "Protection Equipment Multi-function Design R D" project, in the production of the industrial research and research team composed of Donghua University and Shenzhen Qi Pintai Clothing Company, Donghua University relies on the theoretical advantage of "Donghua Fire" laboratory It is mainly responsible for the establishment and improvement of the thermal protection performance assessment system of the firefield combustion fake people. You Potai will conduct multi-year professional research and development, production experience of special protective clothing to Donghua University, and deliver the latest research results to the first line.

According to the introduction, both parties have fully utilized the existing indifferential research integration conditions for project units, and the Chemical Fiber Research Institute of Donghua University and Excelle will participate in the whole process of the company will be quickly applied. In scale production, the process and time of technology and product development is shortened, and the product production is mainly used in existing production conditions. By regularly summarizing the experience of the project, collected the exemptions of experts and engineering technologiesThe discussion, the discussion of the difficulties, focus, research results in the progress of the topic, provide a good atmosphere and the necessary supporting measures for the transformation of technical results and the transformation of technical achievements.

It is reported that "protective clothing multi-function design R D and performance evaluation" project results have been widely used in fire-ranging clothing, protective clothing, anti-chemical services and other protective equipment products.
