Among them, rubber Patient. Experts said that rubber fender The manufacturer shall In order to survive in the fierce market competition, some manufacturers unilaterally take low price competition as the main means, With the development of China's shipping industry, the demand for wharf and ship fenders Low quality raw materials or excessive use of recycled rubber to reduce costs, Rubber fenders are most widely used because of their good toughness and impact resistance. At present, there are many manufacturers of rubber fenders in China, and the good and bad products are mixed. One berth brings great safety risks more and more, Not strictly complying with the relevant standards and processes, which gives the wharf and ships a berth Strictly implement the relevant national standards, strictly enforce the process flow, enhance the ability of independent innovation, The requirements for fender performance are also getting higher and higher. Continuously improve product quality and provide reliable and safe products for China's shipping industry and shipbuilding industry.

It is understood that there are many types of rubber fenders on the market, Inflatable type, lateral loaded cylindrical type (drum type) Butt V type (i.e. X type) and flexible pile type. It mainly includes crimp type When designing and producing rubber fenders, manufacturers should consider the effect on the hull Inflatable rubber fenders are mainly used for berthing And the reaction of wharf berthing members, the size of deformation of the fender after absorbing the kinetic energy of the ship, the reaction of the fender deformation on the hull, the relative stiffness of the fender, the effectiveness of energy absorption of the fender in case of non forward collision, the rate at which the fender slows down the ship's berthing speed, the friction coefficient between the fender system and the ship body, the infrastructure investment and maintenance costs of the fender system and supporting members The contact mode between the hull and fenders and many other factors. Users can choose different types of rubber fenders according to the actual situation, Except tugboat Large tonnage ships are generally not equipped with rubber fenders to protect the wharf and hull.

The market capacity of rubber fenders is relative to the marine main engine, ship plate and other supporting markets in the shipbuilding industry Secret tracking abroad Not very big, the competition is very fierce. Li Haie, Deputy General Manager of China Shipping Rubber (Qingdao) Industry Co., Ltd., said that the annual market capacity of rubber fenders in China is more than 2 billion yuan, and there are only three or four manufacturers with high visibility. They are mainly targeted at key ports and shipbuilding enterprises, with more customized products, so the market share is high and the benefits are good. However, some manufacturers that produce more general-purpose products and have low profits can only adopt the strategy of low price competition, or even use low-quality materials or high proportion of recycled rubber to seek to reduce costs, which is common in a region where there are many rubber fender manufacturers in Jiangsu. Li Haie pointed out that the low-quality rubber fenders are extremely harmful. They not only have a short service life, but also will cause serious damage to the wharf and berthing ships once damaged.

Responsible for China's rubber fender GB/T 21537-2008 Conical Rubber Fender and HG/T 2866-2003 Rubber Fender, CB-T 3948 Marine Inflatable Rubber Mooring Ball and ISO17357:2002 High pressure Floating Pneumatic Rubber Fenders are adopted for inflatable rubber fenders, while the filled floating rubber fender is a new product emerging in recent years, and there is no international standard Song Baoqing, Secretary General of the Rubber Miscellaneous Sub Technical Committee of the National Technical Committee for Rubber and Rubber Products Standardization, who approved the preparation, revision and centralized management of technology, also felt the same way. At present, China's solid rubber fenders and industry standards. Song Baoqing pointed out that the standards of various types of rubber fenders in China are not backward compared with those in foreign countries, but the uneven implementation of standards by manufacturers makes the products good and bad, which brings hidden dangers to the development of China's shipping industry and shipbuilding industry. She said that adding recycled rubber to raw materials can better improve processing performance and meet the requirements of green environmental protection. As for how much recycled rubber will have adverse effects on product quality and service life, there is no quantitative analysis data at present, so the use of recycled rubber cannot be simply questioned. However, the use of high-quality raw materials is an important basis for ensuring product quality, which is beyond doubt.

Rubber fenders are mainly used as ship berthing yards in shipbuilding enterprises We also pay more attention to the cost performance of rubber fenders, but the product quality cannot be ignored. Safety protection during head outfitting. Yangzhou Yuanwang rubber fender said that the quality of the products is the first. If a collision accident happens to a new ship due to the quality problem of rubber fenders when outfitting at the wharf, which leads to damage to the ship's hull, the new ship will have to be reworked and repaired or even delayed. Although compared with ports, rubber fenders are not the main production facilities of shipyards.

Benchmark the development trend of foreign first mover fender technology, actively benchmark and adopt foreign advanced standards, enhance independent innovation capability, constantly improve product performance, and strive to achieve continuous product upgrading. At the same time, we should be self-discipline and self-improvement, and focus on reducing costs and improving products It is the only way for the standardized and sustainable development of the rubber fender industry to enter the enterprise, strictly implement the standards and strengthen the independent innovation ability of the enterprise. Experts said that Chinese rubber fender manufacturers should be smart In terms of quality, we will not engage in vicious competition at low prices. In addition, under the general framework of abiding by the relevant agreements and regulations of the World Trade Organization, China should strengthen the formulation, revision, implementation and inspection of the standards for rubber fenders, strengthen the publicity of the importance of the quality of rubber fenders to the safety of docks and ships, standardize the market order, and make it difficult to produce low-quality rubber fenders without a market.
