The reaction force of a floating pneumatic fender does not increase sharply even under excess load. Therefore, these fenders perform extremely well under such condation and as a result, protect ships and mooring facilities.
2). No deterration or variation in performance
Because pneumatic fenders utilise the compressive elasticity of air, performance deteriation due to fatigue is completely absent. The performance of these fenders remain unchanged at extremely low temperatures, even below - 50'C.
3). Safety realiability
Xincheng pneumatic rubber fender are constructed using several layers of strong tyre cord are therefore extremely resistant to pressure and cutting, and are therefore extremely resistant to pressure and cutting. The larger size ( 2.5m dia upward ) are fitted with safety valve to prevent accident in the event of over copressiom.
4). Construction
The fender body is constructed of an inner rubber layer, reinforcing cord layers and an outer rubber layer. All three layers are bonded together by a combination of heat and pressure over a period of time in a vulcanising oven. Once completed, the fenders are pressure tested before relase.
To provide maximum strength and safety, the out skin of submarine fender is thicker than a normal surface fender.
The outer skin rubber compound is desinged and manufactured to be able to withstand both strenuous use and adverse weather. Condations whilst protecting the cord layers and inner rubber the cord layers are corranged at optimum angles designed to be completely airtight.
5). Simple and low cost installation
The weight of the fenders is supported by the water on which it floats, therefore, the fender can be morred simply by means of a guy rope or chain at minimal cost it can be removed easily to another quay or jetty when not use or transfeered to alternative mooring points as required
6). Chain and tyre net
Almost floating fenders are protected by a chain and tyre net. The purpose of the chain and tyre net is to protec the fender body from damage by sharp objets or protrusions such as rough faced quay walls, to distribute sheer forces along the length of the chain net and to prevent the fender body from having to absorb them.

Graphite Powder soft, dark gray; greasy feeling, can contaminate the paper. Hardness of 1 to 2, along the vertical direction with the increase in the hardness of the hardness can be increased to 3 to 5. Specific gravity of 1.9 to 2.3. In the isolated oxygen conditions, the melting point of more than 3000 ℃, is one of the most resistant minerals. At room temperature, the chemical properties of Graphite powder is relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; materials with high temperature conductive properties, do refractory materials, conductive materials, wear-resistant lubricating materials.
Graphite powder is widely used, according to its different use, we can be divided into the following categories of graphite powder
1. Scale graphite powder
Flake Graphite powder is the most widely used, but also processed into other graphite powder of the original material, scaly graphite powder specifications from 32 to -12000 mesh range, scaly graphite powder toughness is good, with good thermal conductivity and corrosion resistance, can be used as refractory Materials, wear-resistant lubricating materials, conductive materials, casting, Fansha, die and high temperature metallurgical materials
2. Colloidal Graphite powder
Colloidal graphite is formed by the average dispersion of graphite particles below 2u meters in an organic solvent. Colloidal graphite is a viscous suspension of black filaments. Colloidal graphite powder with high quality Natural Flake Graphite performance, in high temperature conditions with special oxidation resistance, self-lubricating and plasticity, at the same time with good conductivity, thermal conductivity and adhesion, mainly used in sealing, metallurgical stripping and other industries
3. Ultrafine graphite powder
Ultrafine graphite powder specifications are generally between 8000 mesh -10000 mesh, mainly used in powder metallurgy release agent, the production of graphite crucible, the battery anode and make conductive materials additives
Nano-graphite powder main specifications for the D30 50 100 400 nm, nano-graphite powder process is more complex, low production rate, so relatively high prices, mainly used in anti-corrosion coatings, lubricants additives, grease additives, precision graphite seal And other industries, in addition, nano-graphite powder in scientific research institutions also has a high application value
