1. Rubber tensile testing machine The tensile, tear, peel, compression, bending and shear tests of rubber products were carried out, measure the performance parameters of the product, such as tensile strength, elongation, elastic modulus and yield strength and son on. 1.1 The testing machine has overload protection device. When the applied force exceeds 2%-10% of the maximum capacity of the testing machine, the overload protection device ensures the automatic shutdown of the testing machine. 1.2 The test machine has limit position protection device. When the beam moves to the upper and lower limit positions, the limit device should act immediately to stop the movement automatically. 1.3 During the test, when the sample breaks, the test function automatically stops, the device automatically stops or according to set mode to returns, then stop.
2. Rubber abrasion tester Rubber abrasion tester is widely used in rubber industry. It is mainly used to test the wear resistance of rubber. 2.1 DIN Abrasion Testing Machine, it is used to determine the wearability of rubber to identify the quality of rubber products. During the test, the rubber rubbed against the gauze on the roller under a certain load, and measure the wear loss. The equipment consists of machine base, roller, weight, reducer, motor, transverse block, cantilever, screw rod, etc. Rubber sample is clamped on the cantilever rotary spring, and the speed reducer drives the roller to rotate. Under the prescribed pressure, the gauze of the roller rubs against the sample to achieve the purpose of wear. The equipment has the advantages of small sample, time saving and no repeated friction.
Silane coupling agent Silane coupling agent Si-69 chemistry is named double [gamma - (triethoxy silyl) propyl] four sulfide.It is often used to treat inorganic fillers such as carbon black and SiO 2. It not only has the function of activator and coupling agent, but also has the function of crosslinking agent, softener and reinforcing agent. It is used as reinforcing agent and vulcanizing agent in rubber industry.
Application: This product is a general amine antioxidant with excellent heat, oxygen and aging properties in rubber industry. It is especially suitable for all-steel and semi-steel radial tires, and is widely used in tires, hoses, belts, rubber shoes, rubber products and other general industrial rubber products, as well as latex products.
Function: Zno-80, as a natural and synthetic rubber active agent, can improve the crosslinking density and strength of vulcanized rubber. Application: can be used in most rubber products. Storage: store for at least one year under cool and dry condition.
Packaging and storage: paper plastic composite bags, pearlescent film or plastic woven bags, 25kg/ bags. Store in dry and ventilated places. For other types of vulcanization accelerators such as MBT (M), MBTS (TM), DCBS (BZ), TBBS (NS), etc., please send message to Email.
Product performance: This kind of product can promote the mixing of different polar rubber, improve its compatibility and process performance. It is suitable for mixing, smelting and calendering operations. It can make the binder bond more closely, so as to improve the effect of mixed coal layer seam, disperse better, mix more evenly, and improve the uniformity of the binder. In addition to increasing adhesive viscosity, it can also improve its fluidity and improve the mechanical properties of vulcanized products. In the formulation of butyl rubber, besides improving the processing performance and promoting the dispersion of fillers, it can keep low modulus and maintain good viscosity after aging, improve the extrusion performance, flexibility resistance and air tightness of the rubber. In addition, it can improve the forming viscosity of synthetic rubber, and has excellent dispersing effect on carbon black and mineral filler, without affecting the low-temperature buckling property.
Product application 1) Increase the dispersion of carbon black in rubber, accelerate the dispersion of carbon black in rubber processing, and improve the technological properties of rubber mixtures such as extrusion, calendering and adhesion. 2) Improve the even dispersion of sulphur in the rubber and prevent rubber from burning. 3) Improving dispersion of white carbon black in rubber compound. 4) Reduce the viscosity of The mixture of rubber. 5) Improve hardness and wear resistance of vulcanizates. 6) This product is suitable for tire processing, such as: radial tire, inclined tire production, this product is also suitable for tape processing, rubber and plastic cable products.
Plasticizer A LTS-82A 86A is a mixture of high molecular weight aliphatic polymers containing unsaturated bonds and active agents. The product does not affect the physical properties of the rubber compound, and has the property of reducing the Mooney viscosity and shortening the mixing time, and the hardness of the finished product is not affected. Inorganic fillers such as carbon black and white carbon have high-performance dispersion, improve extrusion and injection properties of rubber compounds, smooth surface, and significantly reduce internal porosity. This product can reduce the heat generation of the rubber compound, reduce wear, improve tire life and reduce energy consumption.
Product performance: Good protection against ozone and flex fatigue aging. It also has good protection for general aging such as hot oxygen and harmful metals such as molybdenum and manganese. Can be used as a stabilizer for synthetic rubber.
Application description:Rubber adhesive RA produces adhesion through reaction with methylene acceptor. For example, it reacts with rubber binder RE and resorcinol formaldehyde resin GLR-20 to form thermosetting resin. The reaction will occur very quickly at vulcanization temperature. If the reaction occurs before vulcanization, the adhesion of the coordination system will be greatly reduced or even lost. Usually, the rubber, filler and methylene acceptor are prepared at high temperature, and then the rubber adhesive RA is added with accelerator and sulfur in the final refining stage. The recommended proportion is 2-5 rubber adhesive RA for each 100 rubber, and 2-5 GLR-20 resins. Packaging storage and transportation: 1. The rubber adhesive RA is wrapped in woven bags and lined with polyethylene plastic bags. The net weight is 25Kg per package. 2. Before transport and storage, check whether the product packaging is intact. During storage and transportation, the products should be stored in dry, clean and cool warehouses in order to prevent dampness and heat deterioration. 3. The effective storage period is one year.
