Flame retardant clothing thermal contraction
Since human beings discovered and used fire, fire has become an indispensable tool for mankind. Fire helps mankind to create a splendid civilized world while fire is also a double-edged sword. If protection is not good, it will cause irreparable loss and even the cost of life . The fires that cause human casualties are "deflagration fire", "besieged fire" and "splatter fire". The fires that cause human casualties are all above 600 ° C-20000 ° C and above 600 ° C in the flame Flame retardant clothing thermal contraction rate and material rupture threshold energy is the key indicator of fire-retardant clothing protective human safety. This indicator is qualified to ensure on-site personnel to escape the fire of innocence (no 260 ℃ fire). Fire escape from the field of good control of flame retardant fabric thermal shrinkage and the value of the explosion-proof threshold is a key issue when the fire retardant clothing key can play a key role.
According to European statistics, the operator who only touched the switch of electrical equipment for ten years caused 3,000 casualties due to arc explosion. In our country, some workers who wear flame-retardant clothes also cause serious injury accidents caused by burning and explosion accidents have also been reported. Canada, a laboratory burning fire retardant clothing to do the test, some flame-retardant clothing shrinkage rate of more than 30% . This is also the main cause of severe burns when wearing flame retardant clothing in a blast accident.
How to choose a relatively high safety flame retardant protective clothing? In the purchase of flame retardant clothing, first look at the material of the fabric, fiber ratio, etc., can also be removed at the seams of one or two yarns, lit with a lighter to see the flame retardant yarn and shrinkage. Generally para-aramid blended fabric, polyimide fabric in the face of a fire not only has flame retardancy, and shrinkage is relatively low, shrinkage of 100% fire-retardant cotton fabric to be larger, but relatively low strength after carbonization, The nature of other polymer flame retardant fibers, whether blended or pure spinning in the shrinkage after the fire are more than 50%, so in case of fire can not play a very good protective effect.
Long-lasting: Nomex fibers last longer and flame-retardant garments retain their high temperature and flame protection, mechanical strength and breathability well after being washed, exposed or worn.
Low Cost of Wear: It is a cost-effective solution due to the long service life of protective clothing made of Nomex fiber. The excellent abrasion resistance of Nomex fibers is directly related to the longer service life of protective clothing, lower maintenance and replacement costs.
Flame-retardant fabrics in the prevention of fire has a good protective effect, fire-retardant overalls can effectively reduce the fire and sputter metal droplets on the human body injury - YuLong Safety
