Vulcanization process qualityVulcanization process quality control hydraulic O-ring

Vulcanization process is one of the main rubber products processing, under heating or irradiation conditions, hydraulic O-ring rubber compounds and raw rubber vulcanizer chemical reaction, the rubber from the crosslinked macromolecular linear structure becomes three-dimensional macromolecular network structure, resulting in physical and mechanical properties of rubber and other properties have been significantly improved, this process becomes vulcanization, along with the development of technology and production, and high-temperature vulcanizing machine is no longer a necessary condition for vulcanization, some compound may be at lower temperatures, even at room temperature and can be cured drinks, some compounds of available physical methods, such as y-rays so that the crosslinked rubber without the need for a vulcanizing agent, vulcanization broader definition so that, under certain conditions , the linear rubber molecules into the process of a network structure.

Xinhua Xu manufacturer site inspection can be carried out on the production line, grasp each batch, even every moment curing characteristics of hydraulic rubber O-ring rubber meets the product requirements. Used to determine the characteristics of the uncured rubber vulcanization by rubber reciprocating shaker in the mold cavity, the cavity of the reaction torque (force) to obtain a vulcanization curve torque versus time, scientifically determine the curing time, temperature, pressure these three elements, which are key to the final decision of product quality can also be measured with the physical properties of the mix. Raw materials, processes, finished products quality control.

Hydraulic rubber O-ring rubber after vulcanization, some performance will change. Natural rubber, for example, with a higher level of cure, mechanical properties will change. Elasticity, tensile strength, elongation strength, tear strength, hardness will increase, but elongation, compression set, heat fatigue will be reduced; changes in physical properties, air permeability, water permeability reduce insoluble, only swellable improved heat resistance; chemical stability will change remarkably improved.

Since cure meter accuracy and convenience, it has become one of the most effective means of modern hydraulic rubber O-ring rubber plant production process offline (middle production) quality control. Usually stress-strain tests relative error of 3% to 4%, while the rheometer is 1% to 2% or less. Therefore, small differences in the production of each batch of raw materials or mix very easy to find and play a quality control role. control hydraulic O-ring
