(5) The cardiopulmonary resuscitation was carried out on the spot, and the first aid vehicle was moved as soon as possible to quickly transfer it to the nearby Hospital.As an ambulance, you must remember that for all drowning shocks, no matter what the situation is, he must continue to rescue cardiopulmonary rescue from discovery.

[What is a racing goggles] What is the racing mirror how to extend the performance of the swimming mirror anti -fog performance life

The racing goggles actually refer to the swimming mirror that is relatively small and the streamlined shape is relatively small.Common mirrors on the market can be called a racing mirror in general, but it is still much worse than a professional racing mirror.How to choose a good swimming goggle, the appearance, material, performance, and price of each aspect of the good shogue:

Appearance: A well -made swimming moster, the lines of the appearance should be very Smooth, have a good water resistance design, the color is very soft, and it can distinguish it from the appearance that is a racing swimming mirror or ordinary swimming mirror. At the same time, it is exquisiteThe outer box packaging.

Material: The mirror sheet uses impact -resistant polycarbonate (organic glass). The headband, nasal bridge, and mirror frame are made of pure silicone material (sand gel), which is harmless to the human body, and the feel is very soft.Comfort.

Performance: In addition to the functional distinction between the Swimming goggles, the general Swimming goggles, and the myopia goggles.A good swimming moster also has high -performance anti -fog, 100 % anti -ultraviolet treatment, sealing function, and play a role in protecting and preventing damage to the eyes.

price: A well -made swimming moster, the price of a single one is between one hundred and 45 yuan. Of course, the price of some swimming moster contains the price of the brand.

How to properly keep the Swimming goggles?

1. Do not use various organic solvents when removing to avoid deformation or discoloration of swimming moster.

2. In a wet state, putting together with Swimsuits and towels for a long time will cause stains, so put in plastic Bags or small boxes after use.At the same time, keeping it in water for a long time or moisturizing will reduce the anti -fog effect of the Swimming goggles, and it will also cause moldy phenomena.Therefore, long -term collection should be placed in normal temperature and dry and ventilated places, and talcum powder should be added to maintain.

3. When Swimming goggles, please do not place in direct sunlight or extreme high temperature to avoid causing swimming mirror deformation and performance deterioration.

4. Do not use any material to directly wipe the inside of the lens to prevent the fog film.

How to extend the performance life of swimming mirror prevention fog

1. The ultraviolet rays of the sun will destroy the anti -fog performance of the Swimming goggles. Try to avoid placing the swimming moster in the sun.

2. The anti -fog performance of general swimming moster will fail at 80 degrees Celsius.Therefore, you should avoid letting the Swimming goggles contact the thermal source, and avoid placing the Swimming goggles in the storage box irradiated by the sun.

3. The anti -fog performance of the standard swimming moster can be maintained for more than 100 hours. If the mirror surface is found when it is just used, most of the reasons are that the user swims in the unclean or oil -quality water, so that the lens anti -fog surface is attached to a one.Layer oil dirt is blocked by the anti -fog effect. At this time, as long as the oil dirt on the lens with a neutralized lens is used to restore the anti -fog performance of the goggles.

4. Instructions for the use of anti -fog function: Anti -fog agents and anti -fog membranes are all hydrophilic substances. Therefore, when consumers use Swimming goggles for the first time, they should be washed with water.Performance is fully played.

What are the fabrics in the Swimsuit

1, Du FangLaika

Du FangLycra is a artificial elastic fiber with the best foam of elasticity. It can be freely extended by 4 to 7 times. Extension is excellent.Suitable for blending with a variety of fibers, which can strengthen the advantages such as drooping texture, anti -wrinkle and other advantages.DuPont Ledica, which contains anti -chlorine, will make swimwear a longer service life than a Swimsuit with ordinary materials.

2. nylon fabric

The fabric obtained by blending or interweaving the nylon long silk or short fiber and other fibers has the characteristics and strengths of each fiber.For example, the sticky/Jinhuada, using 15%nylon and 85%of the adhesive blending into a yarn, which is doubled by density than weir dense.Wrinkle, dampness drops, and it is easy to droop when wearing.In addition, there are varieties such as sticky/Jin Fanling, sticky/brocade/hair, etc., all commonly used fabrics.

The most common nylon products in the market are nylon 6 and nylon 66.

nylon 6: The full name is polybioneam fiber, which is concentrated by the amide.

nylon 66: The full name is Ji Ji gyacinhamine fiber, which is concentrated from the gimysic acid and the hexyramine.

The common characteristics of nylon 6 and nylon 66: Poor photosyntynce resistance. Under the long -term sunlight and ultraviolet light, the strength decreases and the color is yellow.Huang, intensity and extension decreased significantly, and the contraction rate increased.

nylon 6 and 66 long silk has good low temperature resistance. When it is below minus 70 C, its rebound changes are not great.Its DC conductivity is very low, and it is easy to generate static electricity during the processing process. Its conductive rate increases with the increase in moisture absorption, and increases according to the index function rules with the increase of humidity.nylon 6 and 66 long silk has a strong ability to resist microorganism. Its ability to resist microbial effects in mud or alkali is second only to chlorine.In terms of chemical properties, nylon 6 and 66 long silk has the effects of alkali resistance and reducing agent, but has poor performance in acid resistance and oxidant.

3. Polyester fabric

Polyester fabrics are a lot of chemical fiber clothing fabrics in daily life.Its biggest advantage is that wrinkle resistance and preservation are very good, so it is suitable for coats.

Polyester fabrics have poor moisture absorption, dressed in stuffy, and easy to use electrostatic, dirty dust, affecting beauty and comfort.However, it is easy to dry after washing, and the wetness is almost not reduced, does not deform, and has good washing performance.

Polyester fabrics have high strength and elastic recovery capabilities. Therefore, it is firm and durable, anti -wrinkle and refractory.

Polyester fabric has a good light resistance. In addition to the worse than acrylic, its sun resistance is better than natural fiber fabrics.Especially the ability to resist behind the glass is very good, and it is almost comparable to acrylic.

Polyester fabrics are resistant to various chemicals.The degree of acid and alkali is not greatly damaged, and they are not afraid of mold, not afraid of insects.

Polyester is the best thermal resistance in the fiber fabric. It has thermoplasticity. It can be made of pleated skirt and long -lasting.At the same time, polyester fabrics have poor anti -melting properties, and they are prone to forming holes such as ash and Mars.Therefore, we should try to avoid contact with cigarette butt, sparks, etc. when wearing.

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.
