What are the standards for rubber fender quality inspection items

Specification of rubber fender quality inspection items: 1.The type and specifications of rubber fenders should meet the design requirements and the current national industry standards(rubber fenders)(HG/T2987)and other relevant requirements 2.The fixing structure of the fender and the specifications,quality,and anti-corrosion treatment of the screws,nuts,chains,clamps and other parts selected should meet the design requirements 3.The fixed rubber fender chassis should be in close contact with the dock.The nut should be fully tightened,the screw should be exposed 2-3 buckles,the top of the screw should be retracted into the fender,and the depth should meet the design requirements. 4.The connecting fixture of the suspension rubber fender should be tightly locked. 5.The error value of the allowable error item is the design elevation of plus or minus 20 mm on land,the design elevation of plus or minus 50 mm on the water,the interval of plus or minus 50 mm on land,the interval of plus or minus 100 mm on the water,and the height difference of the D-type rubber fender joint is 10 mm. In the process of the quality inspection of the above rubber fenders,it is necessary to strictly abide by the relevant regulations to ensure the quality is put into use.

Introduction to the installation process of rubber fender

1.Rubber fender installation1.Removal of the original damaged rubber fender1.1.When removing the original rubber fender,damage to the original structure should be avoided.If there is any damage,the concrete upper structure should be repaired before installing a new rubber fender. 1.2.Carefully clean up the original embedded nuts of the rubber fender,and there should be no debris and oil stains that affect the installation.If the nut has been damaged badly,the nut should be repaired.The repair treatment is mainly carried out by replanting the bolt. 2.Construction requirements for installing rubber fenders 2.1.Procurement and installation of fenders in accordance with the requirements of the design drawings and technical specifications.The materials,structures and energy absorption characteristic curves of the fenders should have the manufacturer’s certificate. 2.2.Before installing the fender and gangway,check the shape,size,material and performance of the fender to ensure that it meets the requirements of the technical specifications,and check whether the installation position and elevation of the embedded parts and embedded bolts are accurate. 2.3.During installation,the rubber fender must be in contact with the wharf tightly.The nuts for fixing the fender must be fully tightened,the top of the bolts retracted into the fender,and the embedded depth of the bolts must meet the requirements of the drawings and manufacturer’s instructions.The exposed iron parts must be removed Rust,then use anti-rust paint to protect,rubber fender and gangway quality inspection in accordance with relevant standards. 2.Rubber fender installation and construction technology 1,measurement positioning The personnel release the relevant dimension line of the D300 positioning plate.When drilling the D300 fender,the machined positioning plate should be fixed with expansion bolts according to the relevant dimensions. 2,drilling Electric core drills,air compressors,glue injectors,special round brushes,greasy knives,and necessary protective equipment,such as gloves,masks,etc.,are all necessary for drilling and planting ribs.According to the requirements of the project,choose the drill rod of the corresponding specification.The length of the drill rod should be able to meet the drilling design depth requirements.When do you want to avoid the position of the steel bar in the base material,mark the drilling position,the drilling position should be correct,the hole spacing should be in accordance with the regulations and design requirements,the channel should be dry,otherwise manual drying should be carried out to ensure that the fender bolts and concrete stick It should be absolutely dry before curing. 3,cleaning hole After the hole is formed,the hole must be cleaned with an air compressor and a special round brush to remove the dust in the hole to avoid the isolation of the dust and affect the bonding surface.First use an air compressor to blow up,and then use a brush to clean the channels until there is no dust. 4,cleaning hole Use a brush moistened with acetone to clean the peripheral wall of the concrete tunnel to ensure good adhesion between the substrate hole wall and the structural adhesive.After the acetone volatilizes,put a paper stopper on the tunnel opening in time to avoid contamination and set it aside. 5,adjust glue The best construction temperature of structural adhesive is 15℃~25℃.According to the change of construction temperature,the amount of curing agent can be appropriately increased or decreased through experiments.Precise measuring instruments should be used for the glue preparation,such as balances and platform scales less than 5kg.The glue is first called the glue and then the curing agent.After the two-component resin glue is weighed and mixed,it should be stirred vigorously,and the dosage should not be too much at one time,so as to avoid the long time and the deterioration of the viscose,which will affect the bonding quality of the construction.Generally,the structural glue prepared at a time should be within 30min-40min All used up 6,hole injection glue According to the application form of the anchoring glue(tube type,mechanical injection type,on-site preparation type as above)and direction(up,down,horizontal),adopt the corresponding injection method.Glue injection can be used to fill the pores with a viscose infusion device or other methods.Be sure to fill the pores and remove air so that the gel occupies more than 80%of the pore volume. 7,planting screw After filling the structural glue,immediately implant the screw,and rotate the screw appropriately to expel the air between the glue and the screw,and evenly combine the colloid.Clean up the excess structural glue in the orifice,and set up a temporary support for the longer screw before the anchor is solidified to prevent displacement;the completed screw should be statically cured for Id~3d,and disturbance is prohibited during curing.

What are the production inspection items for rubber fenders

The non-slip rubber fenders for port ships can be divided into two categories according to the structural characteristics:solid rubber fenders and floating rubber fenders. Floating rubber fenders can float freely on the river surface,and can be divided into:air-pumped rubber fenders and refillable rubber fenders according to the difference in the internal buffer material. Solid core rubber fender is the earliest use in history and wide application coverage of port ship anti-collision machinery and equipment. According to the compression condition of the rubber fender,it can be divided into shear type,rotating type and reduced type. According to the structure of rubber fenders,solid port rubber fenders can be divided into drum rubber fenders,D-shaped,cone-shaped,fan-shaped,rectangular frame,and cylindrical rubber fenders. New rubber fender technical inspection items include: 1.Tensile strength 2.Compressive strength at constant extension 3.Extensibility of vulcanized rubber 4.Relative density/ratio 5.Intensity 6.Lashen characteristics 7.Impact characteristics 8.Tearing characteristics(testing of tearing compressive strength) 9.Reducing characteristics(reducing permanent deformation) 10.Adhesive compressive strength and abrasion resistance(coefficient of friction) 11.Ultra-low temperature characteristics,resilience performance 12.Moisture content 13.Glue water content 14.Measurement of liquid-resistant Mooney viscosity 15.Heat resistance 16.Cutting reliability 17.Vulcanized rubber graph 18.Mooney scorch time vulcanized rubber characteristics test
