Marine lifebuoys are a major type of lifesaving equipment

The swimming ring is not a lifebuoy and must not be used as a lifesaving device. The national standards for the implementation of swimming rings and lifebuoys are different, and lifebuoys play a life-saving role, and it has many ancillary functions; Whereas, swimming rings are defined as water toys, and only toy standards are enforced. Therefore, compared with the real lifebuoy, the toy swimming ring is easy to break and leak, the compression resistance is very poor, it is easy to burst, the plastic surface is slippery when exposed to water, it is difficult to grasp, and it can only play a certain auxiliary or protective role in water leisure sports, and it is dangerous if it is brought to deep water.
Whereas, a marine lifebuoy refers to a kind of water lifesaving equipment, which is usually made of cork, styrofoam, or other lightweight materials with a small specific gravity, and is covered with canvas, plastic, etc. A lifebuoy for swimming Xi can also be made of rubber and filled with air, also known as a rubber ring. The periphery of the lifebuoy should be equipped with a floating handle cable with a diameter of not less than 9.5mm and a length of not less than four times the outer diameter of the lifebuoy. The marine lifebuoy should be fastened to four equidistant positions around the ring body, and form four grommets of equal length.
Marine lifebuoys should be resistant to high and low temperatures, oil and fire, and should be able to withstand 90kg weight for 30min without rupture and deformation, without shrinkage, rupture, expansion and decomposition. When the lifebuoy is hung freely, it should be able to bear 90 kg of weight in 30 minutes, and during this time period, the lifebuoy will not break, let alone deform.

Purchase of marine lifebuoys:
Marine lifebuoys are one of the main types of life-saving equipment, usually used as safety protection products in water disaster relief and related production and operation processes.
At present, there are three main types of marine lifebuoy products in China: polystyrene cloth lifebuoy, polyurethane polyethylene composite lifebuoy and crust polyethylene lifebuoy.
Due to the uneven quality of marine lifebuoys, the price is different and the application range is different, so the lifebuoys that meet the configuration requirements should be carefully selected when purchasing.
1. Qualified lifebuoy products shall have relevant material inspection reports, type test reports and bolt inspection certificates.
2. At present, the reference cost price of domestic qualified lifebuoy products is: polystyrene wrapped lifebuoy is about 55 yuan/piece, and crust polyethylene lifebuoy is about 100 yuan/piece. Therefore, lifebuoys that are overly cheap are likely to be products that cut corners and should be purchased with caution.
3. If conditions permit, the merchant is required to conduct necessary verification of the weight, suture quality, strength, floating, high temperature resistance and damage resistance of the lifebuoy according to the requirements of the standard specifications.
