Rubber Injection Machine Development History:

1. Rubber injection machine in the modern process of human society development. The rubber industry is also an indispensable economic industry. In the development of the rubber industry, the progress and development of rubber technology and rubber machinery (or electromechanical) technology have played an important role in promoting. The development of the rubber industry, rubber industry technology and rubber machinery technology constitute the entire technical process and industrial technology system of rubber products. In 1820, the United Kingdom made a single-roller-type rubber mixer driven by manpower. In 1826, the double-roller open type rubber mixer was put into production, which opened the prelude to the production of human rubber machinery. So far, the application of rubber machinery in human society has a history of more than 180 years.
2. Since 1839. A series of rubber injection machines came out one after another. In addition to vulcanization equipment suitable for the application of rubber vulcanization technology, other rubber machinery, such as plunger hose extruder (1858), screw extruder (1879), rubber calender ( 1843 ～ 1900), closed type rubber mixer (1916). And other rubber machinery and equipment. Put into the production process of the rubber industry at that time has played a certain role in promoting the development of the rubber industry. In 1904, the discovery of inorganic vulcanizing agents such as lead oxide and magnesium oxide, especially the discovery and application of organic vulcanization accelerators D and M in 1919, further promoted the improvement of production efficiency, greatly improved the performance of rubber products, and expanded Range of use. In 1920, carbon black was added to rubber, so that the performance of rubber products could be comprehensively improved and improved. Therefore, the application of carbon black has promoted the progress and comprehensive development of the rubber industry. In the early and middle of the 20th century, the Soviet Union, the United States, the United Kingdom, Germany, France and other countries successively invented the synthetic rubber industrial technology. And established a series of rubber synthesis production equipment and factories. Coupled with the large-scale production of natural rubber resources in Southeast Asia, it has opened up a material resource base for the comprehensive development of human modern rubber industry. Rubber is a typical material with high elasticity. Its physical properties are very complicated. Most rubber processing and molding process. There are similar melt flow and deformation processes, and in the processing of rubber products. Raw rubber has to go through the process of plasticizing, kneading, molding, molding, and vulcanization before it can become a product. In modern industrial products. The production and application of engineering technologies such as rubber, plastics, paints, fibers, lubricants, ceramics, etc., have complex mechanical properties for their materials. Based on pure elastic mechanics, viscosity theory or plasticity theory. None can meet the deformation requirements of these materials during processing. Therefore, a research subject based on the mechanical properties of complex media, rheology theory, mentioned the agenda of the study of new human subjects. In 1928, the United States established the "Rheology Society", and in 1940, the United Kingdom established the Rheology Club (later changed to Rheology Society). In addition, the Netherlands, West Germany, France, Japan and other countries have also established corresponding rheological societies. The International Rheological Society was held in 1948. The International Rheological Association was established in 1953. Since then. A fringe discipline involving applied mathematics, physics, elastic mechanics, material mechanics, fluid mechanics, geology, engineering, and other disciplines-rheology came into being and has been widely used. Rheology is not only widely used in the industrial production of rubber, plastics, coatings, printing, silicates, food, etc., but also involves many industrial sectors such as capital construction, machinery, transportation, water conservancy, chemical industry, etc. The process from solid to liquid. Rheology in the rubber industry. Widely used in research and application of rubber products processing and molding. Such as rubber mixing, calendering, extrusion, injection molding and other processing processes. Due to its macromolecular chain structure and movement characteristics, the polymer exhibits 4 physical states in the physical aggregation state: namely, 1 crystalline state and 3 non-crystalline states (glass state, highly elastic state, viscous flow state) . Rubber is highly elastic in normal use. In the process of molding, it is a viscous fluid state. Only after vulcanization, it basically loses fluidity and becomes an elastomer material with high elasticity.
3. Since the end of the 19th century and the beginning of the 20th century, the principles of rubber technology were explored and invented. Especially the research and application of rheology theory. The development of the rubber industry has undergone profound changes in terms of fillers, vulcanization accelerators, and process principles. A qualitative change has taken place in the development of the rubber industry. At the same time, various rubber machinery has also made great progress and development. At that time, the rubber machinery not only had many names, but its structure, specifications, and varieties had reached a certain level of scale, refinement, automation, and linkage. If the transmission power of rubber machinery reaches hundreds of dry watts to thousands of kilowatts. The machine weighs several hundred tons. In the six production processes of rubber production, including plasticizing, kneading, calendering, pressing, molding, and vulcanization. All have fully equipped mechanical devices. Rubber mixing machinery is one of the basic equipments in the rubber industry. Dozens of open rubber mixing machines are currently produced. Mainly used for raw rubber smelting, rubber compound mixing; tablet press for tableting, rubber supply: hot mixer is mainly used for rubber preheating and rubber supply: crusher for natural rubber crushing, etc., The rubber washing machine is used to remove impurities in raw rubber and waste rubber: the pulverizer is mainly used to crush the waste rubber block: the rubber injection machine is mainly used to remove the hard impurities in the reclaimed rubber; the reclaimed rubber mixing machine is mainly used for recycling Rubber kneading: The smoke rubber tableting machine is used for cigarette film tableting, etc .; the crepe tableting machine is mainly used for crepe tableting work: the experimental rubber compounding machine. It is mainly used for experimental work of various small amount of rubber materials.
