The rubber industry involves a variety of technical terms, among which fresh latex refers to white lotion cut directly from rubber trees.
Standard rubber is divided into 5, 10, 20, and 50 particle rubber, among which SCR5 includes two types: emulsion rubber and gel rubber.
Milk standard adhesive is produced by directly solidifying, granulating, and drying latex, while setting standard adhesive is made by pressing, granulating, and drying air dried film.
Mooney viscosity is an indicator for measuring the torque required for rotor rotation in a rubber mold cavity under specific conditions.
The dry rubber content refers to the grams obtained by drying 100g of latex after acid solidification.
Rubber is divided into raw rubber and vulcanized rubber, with the former being raw rubber and the latter being crosslinked rubber.
A compounding agent is a chemical added to raw rubber to improve the performance of rubber products.
Synthetic rubber is a highly elastic polymer made by polymerizing monomers.
Recycled rubber is a material made from processed waste rubber products and vulcanized rubber waste.
Vulcanizing agents can cause rubber cross-linking, while scorching is the premature occurrence of vulcanization phenomenon.
Reinforcing agents and fillers respectively improve the physical properties of rubber and reduce costs.
Softening agents or plasticizers increase rubber plasticity, while rubber aging is the process of gradually losing rubber properties.
Antioxidants delay or inhibit rubber aging and are divided into chemical and physical anti-aging agents.
Frost spraying and sulfur spraying refer to the phenomenon of sulfur and other additives spraying out and sulfur precipitating and crystallizing, respectively.
Plasticity is the process of transforming raw rubber into plastic material, which can maintain deformation under stress.
Mixing is the process of adding a compounding agent to rubber to make a rubber compound, while coating is the process of applying a slurry onto the surface of a fabric.
Rolling is the process of producing semi-finished films or tapes from mixed rubber. The tensile stress, maximum tensile stress, and elongation at break reflect the deformation resistance, damage resistance, and deformation characteristics of vulcanized rubber, respectively.
Tear strength characterizes the ability of materials to resist crack propagation, while rubber hardness and wear represent the ability of rubber to resist deformation and surface wear, respectively.
Rubber density refers to the mass of rubber per unit volume.
Fatigue resistance refers to the structural and performance changes of rubber under periodic external forces.
Maturity refers to the process of parking rubber clots, and the maturation time ranges from the solidification of latex to dehydration.
Shore A hardness: Hardness refers to the ability of rubber to resist external pressure invasion, used to indicate the degree of hardness of rubber. Shore hardness is divided into A (measuring soft rubber), B (measuring semi-rigid rubber), and C (measuring rigid rubber).
Tensile strength: Tensile strength, also known as tensile strength or tensile strength, refers to the force per unit area exerted on rubber when it is pulled apart, expressed in Mpa. Tensile strength is an important indicator for measuring the mechanical strength of rubber, and the larger its value, the better the strength of the rubber.
Tensile elongation at break, also known as elongation, refers to the ratio of the length increased by the tension of rubber when it is pulled to its original length, expressed as a percentage (%). It is a performance indicator for measuring the plasticity of rubber, and a high elongation rate indicates that the rubber has a soft texture and good plasticity. For the performance of rubber, it needs to have a suitable elongation, but too much is not good either.
Rebound rate, also known as rebound elasticity or impact elasticity, is an important performance indicator for measuring rubber elasticity. The ratio of the height of the rebound to the original height when using a pendulum to impact rubber at a certain height is called the rebound rate, expressed as a percentage (%). The larger the value, the higher the elasticity of the rubber.
Tear off permanent deformation, also known as permanent deformation, is an important indicator for measuring the elasticity of rubber. It is the ratio of the length increased by the deformed part of the rubber after it is stretched and pulled apart and parked for a certain period of time (usually 3 minutes) to the original length, expressed as a percentage (%). The smaller its diameter, the better the elasticity of the rubber. In addition, the elasticity of rubber can also be measured by compressive permanent deformation.
