What is the role of a life jacket for life jacket?
What is the material of the life jacket
Life -saving fabric
1. Special nylon material
This kind of fabric is relatively low in price, wide use, but not durable
2. Neoprene choprene rubber (diving material)
This kind of fabric is more expensive, feel soft and comfortable, friction, as long as high -end life jackets can use this fabric.
Life -saving clothing
1. Polyethylene foam plastic
The price of this linoleum is relatively low, with sufficient buoyancy and wide use surface, but the buoyant of the buoyance will change with the time of soaking in the water at about 5%.
2. EPE pearl cotton
The price of this linoleum is obviously more expensive than the foam plastic, and its advantages are obvious.The buoyancy is strong, the life jacket is easy to fold, and it is easy to dry. More importantly, the buoyancy is soaked in the water for a long time.
Life clothing material requirements
1. Plastic should be a soft -closed foam plastic. During the validity period, it is not affected by the erosion of seawater, oil or mold and affects its normal use.It can be stored within the temperature range of -30C to 65C (243 ~ 338K) without damage. It can maintain its performance within the water temperature range of -1c to 30C (272 ~ 303K).
2. Rich kapok oil and must not contain other impurities. The physical properties and moisture content should meet the requirements of norms.After being surrounded by hydrocarbon flames for 2 seconds, the source of the fire should not be burned.Between the kapok and the raw clothing cloth of the kapok life jacket, there must be a waterproof inner cover made of rubber or other waterproof materials.
What is the role of life jacket
1. Help people float on the water
Putting on a life jacket allows people who can't swim to keep their heads exposed to water, thereby reducing the probability of drowning.For those who can swim, the buoyancy of life jackets can save them more physical strength.
2. Cold protection and warmth
Most of the life jackets are made of foam plastic. In the cold water, it can effectively keep warm and reduce the loss of human heat.
3. increase the rescue rate
life jackets are generally bright in color and have anti -light strips, which are convenient to be discovered.At the same time, many life jackets and survival whistle can help people send a distress signal without physical saving.
4. increase the survival rate
Safe clothes can help people float on the surface, which greatly reduces the probability of drowning.At the same time, many life jackets are also equipped with first -aid Bags, which can help people survive better in the harsh living environment.
