Rubber Lining Tanks Parts SBR Rubber Lined Pipe
The Characteristics Of Wear Mining Rubber Hose
1, High Elasticity: Low Elastic Modulus, Large Elongation, Large Deformation, Recoverable Deformation And Elasticity At a Very Wide Temperature (-50~150 c).
2, Viscoelastic: The Rubber Material Is Affected By Temperature And Time When It Produces Deformation And Restores The Deformation. It Shows Obvious Stress Relaxation And Creep Phenomenon, And The Lag Loss Is Produced Under The Action Of Vibration Or Alternating Stress.
3, Electrical Insulation: Rubber And Plastics Are Electrical Insulating Materials As Well.
4, There Are Aging Phenomena: Such As Metal Corrosion, Wood Decay, Rock Weathering, Rubber Will Also Cause Aging Because Of The Changes In Environmental Conditions, The Performance Deterioration, Life Decline.
5, Vulcanization Must Be Used, Except Thermoplastic Elastomers.
6, The Combination Agent Must Be Added.
7, Other Features Such As Small Gravity, Low Hardness, Good Softness And Good Tightness Are All Valuable Properties Of Rubber.
Indicators To Characterize The Physical And Mechanical Properties Of Rubber Lining Tanks Parts SBR Rubber Lined Pipe:
1, Tensile Strength: Also Called Tear Strength And Tensile Strength, The Load On The Unit Section When The Specimen Is Stretched To Fracture, The Unit Is Mpa (Mpa), Formerly a Kilogram Force / Square Centimeter (Kgf/Cm2).
2, Elongation Stress: Formerly Known As Elongation Strength, Which Refers To The Load Per Unit Area When The Specimen Is Stretched To a Certain Length. The Measurement Unit Is The Same As The Tensile Strength. There Are 100%, 300%, And 500% Stresses In Common Use. It Reflects The Ability Of Rubber To Resist External Deformation.
3, Tear Strength: The Load On The Special Thickness Of The Specimen (With a Cut Or Right Angle) When The Unit Thickness Is Taken, Indicates The Tear Resistance Of The Material. The Unit Is Kn/m..
4, Elongation: When The Specimen Is Broken, The Ratio Of Elongation To Original Length Is Called Elongation.
5, Permanent Deformation: After The Specimen Has Been Stretched To Fracture, The Percentage Of The Elongation Of The Gauge Is Not Recoverable. After Releasing The External Force And Placing It For a Certain Time (Usually 3 Minutes), It Is Expressed In%.
6, Resilience: Also Known As Impact Elasticity, Refers To The Ability Of Rubber To Be Restored After Being Impacted, Expressed In%.
7, Hardness: Indicates The Ability Of Rubber To Resist External Pressure. It Is Usually Measured By Shahr Hardness Tester. The Hardness Range Of Rubber Is Generally Between 20~100, And The Unit Is Shao’s a..
4,good water resistance and good aging resistance
It does not produce swelling in water as rubber does, and has an impact on Performance
5, combine well
The Rubber Lining Steel Pipe is tightly integrated with the steel tube, and the PU Lined Pipe is poured into 100% of the steel tube with unique technology, and the unique integral flange process does not appear to fall off, void or partially tear
6, light weight, easy installation
Because the base pipe adopts a thin wall tube, the weight is relatively light, and the time base connection method can be adopted: a flange joint, a flexible pipe joint and a welding joint
The products are mainly used: Rubber Lined Steel Pipe has excellent abrasion resistance, acid resistance, alkali resistance, anti fouling, radiation resistance, hydrolysis resistance, high elasticity, resistance to mechanical impact performance. Can be widely used in electric welding, carbon, mine, building materials, chemical industry and conveying of pulverized coal, ash, slag, molten aluminum, mud grinding of granular material and corrosive medium.

One, natural attribute
Natural rubber is produced by artificially cultivated trefoil rubber tree, produced by coagulation and processing. Its main component is polyisoprene, with a content of more than 90%. In addition, it contains a small amount of protein, fat, acid, sugar and ash.
Two, variety classification and quality standard
According to different manufacturing processes and shapes, natural rubber can be divided into tobacco sheet rubber, particle glue, crepe glue and latex. But the market is mainly smoke glue and particle glue. The glue is made by solidification, drying and smoked. The natural rubber imported in our country is mostly smoked gum, and the particle glue is made by the technology of solidification, granulation and drying. The domestic natural rubber in our country is basically granular rubber, also called standard glue. The gum gum is generally classified according to its shape. It is divided into grade two, grade one, grade two, grade three, grade four, five, and so on. It is classified as external glue, and the particle glue is classified according to international unified physical and chemical efficiency and index. These physical properties include impurity content, plastic initial value, plasticity retention rate, nitrogen content. Quantity, volatile matter content, ash content and color index are seven items. Among them, the impurity content is the leading index. According to the amount of impurities, it can be divided into five levels: 5L, 5, 10, 20 and 50. The level of delivery of natural rubber contract in Shanghai futures exchange is domestic grade 1 standard adhesive SCR5 and imported cigarette glue RSS3, in which domestic first grade standard adhesive SCR5 is also known as No. 5 standard glue, and the quality indexes of version 8090-87 of natural rubber issued by the National Technical Supervision Bureau are implemented. Imported cigarette glue RSS3 executive international rubber quality and Packaging Conference “quality of natural rubber grade and packaging international standard” (green leather book) (1979 Edition).
Three. Main uses
Natural rubber is widely used in industrial, agricultural, national defense, transportation, transportation, machinery manufacturing, medicine and health, and daily life, for its strong elasticity and good insulation, plasticity, water insulation, tensile and wear resistance, etc., such as tires used in transportation and transportation, and industrial transport belts. A belt, a variety of sealing rings; medical gloves, blood transfusion tubes; rubber shoes, raincoats, and warm water bags used in daily life are made of rubber as the main raw material; aircraft, artillery, tanks, and even rockets, satellites, spaceships, and spaceships in the field of science and technology are needed on national defense. A large number of rubber parts.
