project true false selling price The cost of a marine life jacket, including raw materials, processing costs, management costs, financial costs, etc., is currently around 100 RMB for each life jacket. Raw materials for poor quality life jackets are not high in demand, rough in processing, and non-standard in management, and cannot be controlled in accordance with the requirements of the quality system. Under normal circumstances, the price of fake and fake life jackets is only about 20 to 40 yuan. Some bad factories deceive customers and use life jackets to impersonate marine life jackets. Product Identification The marine life jackets produced by regular manufacturers and inspected by CCS shall have complete Chinese and English product identifications, including product name, production unit, product model, implementation standard, approval certificate number, accreditation authority, scope of application, and ship inspection mark. Poor quality identification of lifesaving clothing products, identification content is incomplete, there is no implementation of standards, certificate number, etc., and is only displayed in Chinese. The CCS refused to inspect such products. Therefore, there was no CCS ship inspection mark, or the factory did not use CCS ship inspection marks without the authorization of CCS. Fabrics The marine lifejackets are thick, woven, and are brightly colored (yellow-orange). When the fabric tears forcefully, there is no noticeable slippage in the texture of the fabric. Poor life jackets are made of common fabrics that are low in strength, faintly colored, easy to age, and prone to quality variations in harsh environments. The more common defects are thin fabrics, easy drawing, etc. Buoyancy material The buoyancy material of the marine life jacket is tight and can quickly rebound after being pressed by hand. When immersed in water, it absorbs very little water. The thickness is generally greater than 10 cm. The poor quality lifejacket has not been tested and tested. It has a lighter feel, softer material, and can't rebound quickly after hand pressure. After immersion in water due to more water, feel significantly heavier. The thickness is generally less than 10 cm. Reflective tape Reflective effect is good, can reflect light from all angles, generally composed of polygonal lattice pattern. The total area of ​​the reflective tape on each lifejacket should not be less than 400 cm. The reflective material of poor quality life jackets is cloth reflective material, which has poor durability, aging resistance and light reflection. Fasteners Has a strong buckle or buckle, buckle tough. No buckle or buckle, tied with a tie or buckle with light and easy to break. Webbing suture High-quality ribbon stitching structure is tight, color is good, sewing process is fine, and tie straps should not be less than 3 quilting threads, anti-aging, and high tensile strength. The poor quality life jackets have poor color and burrs on the seams and webbing. They cannot resist aging, have rough sewing, loose ribbons, and do not meet the requirements for tensile strength.
