cylindrical type pneumatic boat rubber fender with competitive  price 1. General introduction ISO17357:2014 Floating pneumatic rubber fender is an anti-clossion device for marine application in the world. It is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the sea surface and work as a shock absorber when ship to ship transfer operation and ship to dock berthing and mooring operations. Evergreen floating pneumatic rubber fenders fully company with all requirements on ISO17357:2002 Sstandard. Our products are certificated by CCS, DNV, GL, LR and BV.  2.  Construction  features The basic body construction of  Floating pneumatic rubber fender consists of outer rubber layers, synthetic-tire-cord layers and inner layers. Please take the picture for reference. All of these layers are vulcanized together ,and then compress air  inside to enable the fender to float on the sea surface. Yokohama Pneumatic rubber fender are available from 500X1000mm to 3300X6500mm, including all the standard and no-standard specifications. 4.Pressure requirements of Yokohama type Pneumatic Rubber Fenders - Evergreen-Maritime manufactures marine rubber fender with 50kPa (pneumatic 50) and 80kPa (pneumatic 80) initial pressure. The internal pressure, endurable pressure, safety-valve setting pressure and hydraulic test pressure are also in compliance with the requirements of ISO17357:2002.
â—The fineness of processing strength reaches 1-74um, and the particle size distribution is narrow and there is no large particle;
â— Materials collide with each other for crushing, can process Mohs hardness 1-10 materials, wear is small, the product no iron pollution;
â— Reasonable cooling flow field, due to the sharp expansion of air flow in the crushing process, the air flow temperature is reduced, so it is particularly suitable for the processing of heat sensitive, low melting point materials;
â— Optimize the structure of the equipment, improve the performance of the equipment, can be effective dispersion and dissociation of agglomerative ultra-fine powder, polymer;
â— Original collection flow field technology, can obtain good crushing efficiency and strict particle size cloth, crushing particle size can be arbitrarily controlled between 1-74um, very fine up to sub-micron level, small material loss, can realize the crushing cavity material basically completely crushed, little participation, equipment wall without dead Angle, easy cleaning, fully in line with GMP standards;
â— Original special jet and split flow field technology, suitable for the processing of dry adhesive materials;
â— Can be mixed and crushed several kinds of materials, and has a good mixing function;
â— Fully sealed negative pressure operation, no environmental pollution.
