What are the life jacket materials and matters needing attention?

1.Life jacket materialFabric:

Special nylon materials are relatively cheap and widely used, but not durable.

2. Neoprene (diving material) is expensive, soft and comfortable, and resistant to friction. Only good life jackets will use this fabric.

2.Life jacket materialLiner:

1. Polyethylene foam

They are relatively cheap, have sufficient buoyancy, and are widely used, but the buoyancy of buoyancy will change by about 5% when immersed in water.

The price of EPE pearl cotton is significantly higher than that of foam plastic, with obvious advantages. The buoyancy is strong. This life jacket is easy to fold and dry. More importantly, when it is immersed in water for a long time, its buoyancy will be significantly reduced.

3.Life jacket materialRequirements:

1. The plastic should be a soft closed-cell foam, which is not affected by seawater, oil or mold erosion during the validity period, and affects its normal use.

2. Kapok is rich in oil and does not contain other impurities. Its physical properties and water content should meet the specification requirements. The ignition source must not burn continuously after being surrounded by a hydrocarbon flame for 2 seconds.

the role of 4. life jacket:

1. Help people float on the water. Wearing a life jacket can reduce the likelihood of drowning by keeping people who can't swim out of the water.

2. Cold-proof warm life jackets are mostly made of foam, which can effectively keep warm in cold water and reduce body heat loss.

3. In order to increase the chance of being rescued, life jackets are usually brightly colored and have reflective strips for easy detection.

Life jackets can help people float on the water, greatly reducing the possibility of drowning. At the same time, many life jackets will be equipped with first aid kits, which can help people survive in the harsh living environment.

5. life jacket purchase knowledge

1, marine life jacket: is also one of our most used life jackets. It is made of EVA foam material and compressed three-dimensional modeling. Its thickness is about 4cm (China produces 5-6 kinds of thin hair materials with a thickness of about 5-7cm). The life jacket produced according to the standard specification has its buoyancy standard, which is generally 7.5kg/24h for adults, that is to say, the buoyancy can still reach 7.5kg after 24 hours of immersion in the sea.

2, automatic telescopic life jacket: generally used for boating fishing. The inside is made of double-layer high-strength chemical materials. If you fall into the water, press the button on the right, the left will automatically inhale air, and the reflector will store air until it is full. The buoyancy of this life jacket is 10kg/24h, but contact with the reef should be avoided as much as possible to prevent damage.

3. Rock fishing cross-arm life jacket: rock fishing supplies. He had a pair of buttons in front of him. When you put them on, you need to pull them well. In addition, there is a pair of oval luminous body on the chest or shoulder of the life jacket, which is mainly used for sea rescue. Therefore, when choosing, pay attention to whether the seam is open, and then consider its color and fabric.
