What are the types and performance indicators of inflatable life jackets?

The correct way to wear the bloated life jacket

1. Put your head into the life jacket.

2. Tie the straps on the left and right sides.

3. Pull the tension on the left and right sides, the inflatable valve is opened, and the life jacket is inflated within a few seconds.

The inflation function of the qi -blee -type life jacket

1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.

2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.

3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.

What are the types of qi -style life jackets?

Blay -type life jackets are divided into three types according to the appearance style:

1. Vest -style qi qi and life jackets are commonly known as horses -type qi qi life jackets.

2. scarf -style qi and life jackets are tied to the neck like a scarf.

3. Belt Bloating life jacket, also known as qi -type Belt life ring, water seat Belt.

There are two specifications of all styles of qi and life jackets, one manual type and one automatic type.Suitable for fire, maritime police, water police, armed police, border defense, maritime affairs, fishery administration and other units to engage in water rescue activities.

The performance indicators of qi -blee -type life jackets

1. Automatically inflatable within 5 seconds of water, generate more than 15 kg of buoyancy.The 24 -hour buoyancy loss is less than 5%, and the performance of the main accessories and materials meets national standards.

2. The airbags are made of imported polyether TPU materials, which have excellent aging resistance and hydrolysis characteristics.

3. The dry side of the water is greater than 120mm, and the backward angle is 20-50 degrees.

4. The product is standard for search whistle and reflective stickers.

What are the fabrics of qi -qi -type life -saving clothing

Bid-type life jackets use TPU fabrics, TPUs (Thermoplastic Polyurethanes), and thermal plastic polymethlate, which is a linear embedded cluster composed of low polymer polymirol soft segments and diisocyanate-expansion hard segments.The TPU can be made of saliva, film blowing, pressure delay, or coating, which has the excellent characteristics of good elasticity, strong toughness, abrasion resistance, good cold resistance, and environmental protection and non -toxic.TPU fabric has the following characteristics:

1. Hardness planning wide

After changing the ratio of the components of the TPU composite fabric, the Tent cloth can get products of different hardness, and follow the hardness of the hardness. Its product still adheres to excellent elasticity and abrasion resistance.

2. High mechanical strength

The carrying capacity, impact resistance and shock absorption function of TPU composite fabric products are excellent.

3. Extremely cold -resistant

The glass state changing temperature of the TPU composite fabric is relatively low, and the canvas factory still adheres to excellent elasticity, softness and other physical functions at minus 35 degrees.

4. Good processing function

TPU composite fabrics can be processed with common thermoplastic materials, such as injection molding, extrusion, pressure extension, and so on.At the same time, the TPU composite fabric/cloth processing with certain polymer materials can obtain a polymer alloy with complementary functions.

5, oil resistance, water resistance, mold resistance.

6. Good recycled utilization.

There are two methods of TPU composite fabric. One is called and then sticked: first make it into a TPU film, then fit the glue with the fabric, and the other is called online composite: apply the glue on the fabric may not be glued.The fabric is made into a TPU composite fabric or clipped mesh.
