1. What are the differences between swimming rings and life rings

1. Different weight

Swimming ring: It is a water toy with light weight, easy damage, easy leakage, poor pressure resistance, and easy explosive.

Life Circle: It is a type of water life -saving equipment. The production process is complicated and the requirements are stricter.The weight should be greater than 2.5.With a spontaneous smoke signal and a life ring attached to the spoiler light, the weight should be greater than 4.

2. Different materials

The Swimming ring is just a kind of water inflatable toy, which is made of plastic and cannot be used for life.

The life ring is a closure foam material, which is a polystyrene material, which is wrapped in glass fiber cloth outside, and three layers of phenolic resin should be applied.The body of the life circle must have fluorescent strips for convenience.

3. Different uses

The Swimming ring has the characteristics of security and hygiene, and is the best supplies for baby fitness and games.It is cute, novel in style, bright colors, easy to carry, and not greasy to play. It is the latest playmate of the baby.

The lifebuilding circle refers to a type of water life -saving equipment. It is usually made of cork, foam plastics or other light materials with smaller proportion, with canvas and plastic on the outer bread.The life -saving circle for swimming exercises can also be made of rubber, which is charged in the inner air, also called a rubber ring.

2. How to buy swimming rings correctly

1. Reject "Three None" products and recognize the 3C certification logo.When buying a Swimming ring, you must first see if the Swimming ring indicates information about manufacturers, manufacturers' address contact information, production date, shelf life and other information, and whether there are 3C certification signs.

2. Choose a Swimming ring with smoothness, thick material, and clear contrast between the color and the water surface; the soft, elastic Swimming ring should be selected on the fabric to make it buffer when it collides, and avoid damage.

3. When buying a Swimming ring, you can choose a product with multiple airbags and have a separate inflatable mouth, so that even if one of the airbags leaks, it can have sufficient air support.

4. Pay attention to whether the Swimming ring has a pungent smell. The smell may be made of inferior plastic, which contains chemical composition that is harmful to the human body.

1. How can the swimming rot quickly inflatter and deflate

The Swimming ring is fast -inflated, but it is particularly slow when airing, because it uses the principle of ordinary tires.Then we can change the size of its deflection mouth to achieve the rapid release of all gas and increase the exhaust holes. Naturally, it will be much faster.

1. Wipe the inflatable mouth of the Swimming ring to prevent the foreign body from blocking the foreign body. Gently drag out the inflatable cutting door out or launch it on the surface of the Swimming ring and open the plug.The straw is inserted vertically into the cutting door, pushing the straw to open the inner wall of the straw, or simply make the straw through the cut door into the inner danger of the Swimming ring.You can easily get inflatable swimming rings.After full, the hand is pinching the parts connected to the inflatable mouth.

2. When moving, you can use a stuck or toothpick to extend from the pores and press it inward, so that the deflation is much faster.

2. How to save the Swimming ring is better

1. First, wash the Swimming ring after washing, otherwise the material is easy to get back.Put the air in the Swimming ring, insert it with something like a small stick, and then roll it up. Remember to roll it up, not folded.Rolling into a circle is like a thousand -layer roll cake.

2. It is best to buy a small storage box and put it inside. If there is no pet or mouse, it is easy to be bite.And this will not be messy, and it will not be found when it comes.If you use it then, you can use it to use it.

3Installation, liquid may enter the carcass layer through the internal air dense layer, which will cause sudden damage to the Swimming ring.

1. When did the Swimming ring invented?

In the past, some people thought that the lifeblonga was introduced into China from Europe and the United States. In fact, the lifeburn circle was created and invented by our Chinese.

As early as two or three thousand years ago, my country had a "life -saving circle", which was the dry gourd.At that time, the clever Chinese people found that holding the dry gourd melon can float the body on the water and drown the gourd melon to become the most primitive life -saving equipment.Later, most of the vessels sailing at sea brought gourds to prevent unexpected.It can be seen that the ancient people of my country used the dry gourd to cross the river. This is the most primitive lifebuilding circle.

In the song Dynasty, the production method of the lifeburn was a step forward. Some people began to use soft wood, reeds, etc. to be prepared into a ring object, so that people can drill in and make the ring supporting people.The gourd melon is much more convenient, and it has become a veritable life -saving "circle".Han Shizhong, who was anti -Golden, who was anti -golden hero Yue Fei at the same time, sent Wang Quan to Jinshan to fight against the enemy. Before leaving, Han Shizhong ordered him not to use the boat to cross the river, so as not to be found by the enemy.So Wang Quan sent a circular floating ring made of cork to each soldier, allowing them to restrain the floating ring on the waist and cross the river.The soldiers quietly crossed the river under the leadership of the royal power.At that time, the floating ring used by the royal power was the predecessor of the modern lifebing circle.From the time to modern times, with the application of new technologies and new materials, various life -saving equipment appeared: lifeboats, life jackets, and uniform.But the traditional equipment of the lifebuilding circle is still retained by people, and it is still the easiest life -saving Tool.

2. What materials are the swimming rings made

The material of the inflatable Swimming ring is relatively single. Most of them are made of ordinary PVC materials. Most of the domestic PVC materials are the main in China. The 6P environmental PVC is better.

3. What material is the best material in the life circle

At present, the main forms of domestic Lifeline products include polystyrene packaging cloth life rings, polyurethane polyethylene composite lifebladder, and knot -type polyethylene lifebirth circle.

1. Polyetstics packaged cloth life ring

The polystyrene cloth life ring is mostly used in the inland rivers. The rim core material of the life ring is made of polystyrene material.Generally, the production process is to wrap glass fiber cloth in the rotary core material, and apply 3 layers of phenolic resin to form a sealed glass steel shell, and then wrap and apply several layers of paint.

2. Polyethylene compound lifebuilding circle

Polyethylene composite lifebrows are used as high -density polyethylene materials as shells. The internal rechargement of polyurethane foam materials is a new type of lifebuilding in China.At present, more than 100,000 annual output has reached more than 100.The composite life ring solves the problems of oil -resistant oil tolerance of polystyrene bales, in high temperature environments and long -term radiation in ultraviolet radiation, which is prone to aging, paint layer peeling, and complex manufacturing process.This type of lifebuilding has the advantages of solid color, Smooth surface, anti -aging, large mechanical strength, and corrosion resistance, but production costs are higher than that of polyethylene Bags.

3. Knotchye polyethylene foam life ring

The polyethylene lifebuilding circle is also known as the citrine polyethylene foam lifebuilding circle. It is made of low -density polyethylene foam. It is a new technology product. At present, only a few companies in China can produce.The circle of its products is only made of a single material of polyethylene. The circle body is full of elasticity. The surface is bright and beautiful on the surface. The strength, buoyancy, oil resistance and erosion resistance are not comparable.At present, the domestic product has high technology and high costs. The products produced only supply military or exports.

What is the size of the life circle

The specifications of the lifebuilding circle are required, the lifebuilding circleThe outer diameter should not be greater than 800, and the inner diameter should not be less than 400.1.5kg Children's Life Circle size is 510*340*90 (mm); 2.5kg adult life -saving circle size is 720*440*105 (mm); 4.3kg adult life ring size is 760*440*105 (mm).The periphery of the life ring should be equipped with a cable cable with a diameter of not less than 9.5 and not less than the outer diameter of the life ring.This cable should be tightly tightened in the four distances around the circle and forms four equivalent rings.

Technical requirements for life -saving circle

1. There is an outer diameter of not more than 800mm and an inner diameter of not less than 400mm.

2. Made of natural buoyant material, its buoyancy shall not rely on lamp -hearted grass, cork plane slices or cork particles, any other loose granular materials or any air room dependent on inflatable.

3. The iron blocks with no less than 14.5kg in freshwater reaching 24h.

4. It has the quality of no less than 2.5kg.

5. Falling the fire is completely surrounded by 2S, not burning or continuing melting.

6. Its structure should be able to withstand the height or 30m (taking the big) from the storage position to the lightest carrier.

7. If the lifebuilding circle is equipped with a spontaneous smoke signal and a rapidly throwing device with a self -lit light, it should have the quality that is sufficient to operate the rapid throwing device.

8. There are 1 handle cable with a diameter of no less than 9.5mm and a length of no less than 4 times the outer diameter of the life ring.The handle cable should be around the life circle and fix it at 4 equal points to form 4 equal rings.

9. The life of the life of the river waters is not less than 1.5 kg. The purpose is to enhance the intensity of the life of the life of the life, and to the accurate throwing when the rescue falls, it is not affected by the wind and waves.

What are the belongings of the lifeburn circle?

1. Self -light floating light

Each Ship at least half of the life circle should be equipped with a self -lit light that meets the requirements of the rules so that it can display the location of the lifebuilding circle and its users at night, which is convenient for searching for rescue.At present, the self -bright floating Lights on the Ship are mainly used as the power supply.Once the life ring is put into the water, the bright floating light is automatically floating on the water surface, and a white flash emits.

2. Smooth smoke signal

There are at least two life -saving circles near each Ship's cab. At least two have spontaneous smoke signals that meet the requirements of the rules. When the lifebuilding circle is thrown, the smoke can floats on the water with the life circle and emits orange -yellow smoke.

3. Floating Life Covers

At least one life ring of the Ship should be attached to the requirements that meet the requirements. The length is generally thirty meters, or twice the distance from the Ship's light load water line to the storage area. The two are large.

Safe Circle price and Selection skills

1. Qualified life -saving circle products shall have relevant material inspection reports, type test reports and Ship embolism inspection certificates.Although there are very few complaints caused by quality problems in the life circle, any regular product should have basic elements such as factory names, factories, qualification certificates, and production date.At the same time, it should be operated in accordance with the relevant quality standards, and the use instructions of Chinese words should be attached.Because the lifebuilding circle is a special life -saving equipment, you must keep your heart when you buy it to avoid brewing during swimming.

2. At present, the reference cost price of the domestic qualified life -saving circle products is: about 55 yuan/piece of polystyrene clothing cloth, and about 100 yuan/piece of citrine polyethylene lifebirth circle.Therefore, the life circle with too cheap prices is likely to be a product that cut corners and should be purchased with caution.

3. Under the condition of conditions, the merchants are required to conduct necessary verifications of the weight of the life of the life circle, stitching quality, strength, floating, high temperature resistance, and resistance to damage in accordance with the standard requirements of the standard specifications.

What are the differences between lifeburn and swimming rings

Swimming ring: It belongs to water toys, with light weight, prone to damage, leakage, poor pressure resistance, and explosion.The plastic surface is slippery when water is wet, and it is difficult to grasp.It can only play auxiliary or protective effect in water leisure movement, and bring to the danger of deep water in the deep water area.

Life Circle: One of the water life -saving equipment, the production process is complicated, and the requirements are stricter.The rim core material uses a closed -hole foam material, that is, the polystyrene material, wraps the glass fiber cloth outside, is also applied to three layers of phenolic resin, and then the sails are covered with several layers of paint.The life of life must have fluorescent strips for convenient rescue.

Not a lifebuilding circle, you must not be used as a life settlement.The national standards performed by the swimming circle are different from the national standards performed. The lifebuilding circle is a life -saving function. It has many accessories; while the Swimming ring is defined as a water toy, it is only the toy standard.Therefore, compared with the real lifebuilding circle, the toy swimming circle is prone to damage the air leakage, the pressure resistance ability is very poor, it is easy to explode, the plastic surface is slippery, it is difficult to grasp the grip.Auxiliary or protection is dangerous if it is taken to the deep water area.

How to use the life circle

1. Soak in the water temperature of 30-40 degrees before the life ring is used. The plastic softening of the life ring and the air inside can only be used after the water temperature.

2. Do not charge too much when the life ring is inflated, because the current indoor temperature is limited, and if it is too full, all of them are cold air. Once put in the hot water of the swimming pool, the life ring will be full due to inflatable heat and swelling.The principle of cold contraction burst at the interface.

How to use the Swimming ring

1. Remove the white rotation before inflating. After the gas is filled, make sure that the rotor is correct and completely inserted. Do not dial the rotor when used.

2. When a child uses a Swimming ring, adults must take care of it.

3. When a certain time, inflatable toys expand slowly.Before continuing to play, you must ensure that it will be inflated and reach the saturation state.

4. Before playing this toy, make sure that there are no sharp things or items around or on the ground.

5. Children's swimming circle, playing together for two children is very dangerous, so they do not advocate two children to play together.

6. The inflatable Swimming ring cannot be excessive.

What are the advantages and disadvantages of the swimming circle

advantage:

1. The price is cheap, the pattern is good, and it is loved by young men and women in children.

2. When the inflatable carriers are convenient, blow the air when taking it out and play with the swimming pool.

shortcoming:

1. The first is that the weight is too light and it is difficult to throw it accurately.

2. Poor pressure resistance and easy to break.

3. It will become wet when it encounters water on the surface of the plastic surface, which is difficult to grasp.

4. Some swimming rings are three -free products.
