Double: 84cm x 28cm x 14cm, buoyancy 220N.
3. Package size:
Single: 72cm x 28cm x 15cm,
Double: 86cm x 50cm x 35cm.
4. Material: polyethylene plastic
5. Process: roll molding (there are many processing and molding processes for plastics and its composite materials. Besides common extrusion, injection and blow molding processes, roll molding is also a processing method for plastic products. Step: pour the plastic material into the mould first. The blow causes the mold to rotate continuously along two vertical shafts and to continue heating. Under the action of gravity and heat energy, the plastic material in the screen mold is gradually evenly coated and melted and adhered to the entire surface of the mold cavity to form the desired shape. After cooling and shaping products.
6. The picture shows the new double color: red, yellow, blue and green.
7. Delivery with goods: belt + safety hook + high frequency whistle for help! (note: old models are not given!!! )
8. The packaging is made of 5-layer corrugated paper box with a thin film wrapped around the product.
The new model adopts the internationally accepted molding process, and the steps are as follows:
1. First add the plastic raw material of the quasi-weight measurement into the mold.
2. Make the mold rotate continuously along the two vertical axes and continuously heat it up.
3. Under the action of gravity and thermal energy, the plastics raw materials in the mold are gradually evenly coated and fused to the entire surface of the mold cavity, forming into the required shape.
4, after cooling and shaping products.
Process comparison:
There are many processing and molding processes of plastics and its composite materials. Besides common extrusion, injection, blow molding and other processes, roller molding is also a processing method of plastic products. The development speed of foreign plastics rolling industry is very fast, while the development speed of domestic plastics forming industry is lower than other plastics forming industry due to various factors, such as the slow processing cycle and the limitation of materials used.
Torpedo rescue pontoon should be prepared in bathhouse, swimming pool, boat, lifeboat station, lifeboat station or a specific place.
The rope connecting the buoy to the strap should be kept in standby mode at all times. The rope should be tightly wound at the center of the buoy and the belt should be inserted into the rope after two laps, so that the back strap can be exposed, so that the rope can be quickly pulled out of the rope when rescuing, and the rope can be unfastened automatically.
At the beach, the rescue pontoon is fixed upright by burying one end of the rope free connection into the sand. On the lifeboat platform or iron frame, the pontoon rope harness can be tied loosely after, and then the pontoon rear handle, hook on the rack hook.
The sea or large water area and the mobile water rescue should be equipped with frog shoes. When the rescuer enters the water, he should put the buoy strap on his shoulder, place it under his arm, or hold it with one hand, and hold the frog shoe in another hand. Under suitable conditions, when entering the water with the beach, he should lead into the water and wade into the water to the depth of his knees, that is, he should put on the frog shoes, throw the buoy behind him, and swim to the drowning person through the shallow place. The rescuer should always pay attention to the drowning person, so as to avoid losing the drowning person.

1. We all know that the buoyancy of air is great, and we have also heard that many lifejackets made of foaming materials are soaked in water for too long, and the PE foam material will absorb water and cause the attenuation of buoyancy. Similarly, the lifeboat torpedo buoy bar made of PE or PVC or EVA foam material will also absorb water, and buoyancy will also decline with time. When the rescue team fails to arrive at the scene in a timely manner, your foaming lifebelt will absorb water slowly with time and the buoyancy will be reduced. Your original choice of purchase also determines your survival chance of floating on water. You should consider this important factor before you purchase.
2. The foamed floating strip is too light to be thrown and the rescue opportunity is lost: When you are engaged in water leisure activities in streams or lakes on the beach, when emergency rescue of water surface occurs on the scene, if you have a torpedo buoy (canister) at hand, you can immediately throw the torpedo buoy directly to the caller, you can immediately save him. And general foam article lifesaving float out because is too light in weight easy to mess with the wind wave cannot be effectively controlled when the stroke direction so sometimes have to find a buoy article master article will float swim to HuJiuZhe to rescue effect, but often on time already too late and missed the gold rescue time another swim you send floating people must pay attention to their own physical strength can by back or physical strength overdraft or foot cramps and often the risk of life in life. If you you don't have to personally with the buoy cylinder adventure save people, even if you insist on the buoyancy of water rescue he buoy tube is enough for two or more persons. So choose buoyancy secure your environment Big.
3. The torpedo buoys (barrel) surface drag resistance smaller row water: when dragged torpedo buoys swimmers in the water (barrel) prior to the torpedo buoys (barrel) pointed round design line shape dragged the surface water resistance is small, the torpedo buoys (barrel) front end tip circle design consistent with real torpedo low water resistance design, the design of the head is pointed is to reduce water resistance, in addition the torpedo buoys (barrel) only unilateral semicircular curve contact with the surface of the water and generally identical to the design principle of the bottom is also in order to reduce water resistance.
4. Torpedo buoy (barrel) has a long life
Under normal use if good maintenance for more than 3 years or longer
