Development History of Rubber Injection Machine:

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 advancement 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 human-driven single-roller rubber mixer. In 1826, the double-roller open-type rubber mixing machine was put into production, which opened the prelude of human rubber machinery production. So far, the application of rubber machinery in human society has been more than 180 years old.
2. Since 1839. A series of rubber injection machines have been introduced, in addition to vulcanization equipment suitable for rubber vulcanization technology, other rubber machinery, such as plunger hose extruder (1858), screw extruder (1879), rubber calender ( 1843 ~ 1900), closed type rubber mixing machine (1916). Rubber machinery and equipment. It was successively invested in the production process of the rubber industry at that time, which 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 Use range. In 1920, the addition of carbon black to rubber made the performance of rubber products fully improved and improved. Therefore, the application of carbon black has promoted the progress and overall development of the rubber industry. In the early and mid-20th century, the Soviet Union, the United States, the United Kingdom, Germany, France and other countries have invented 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 the modern rubber industry. Rubber is a typical material with high elasticity. Its physical properties are very complicated. Most rubber processing and forming process. There are approximate flow and deformation processes of the melt, and during the processing of rubber products. Raw rubber must pass the process of mastication, mixing, molding, molding and vulcanization to become a product. In modern industrial products. The production and engineering techniques of materials such as rubber, plastics, paints, fibers, lubricants, ceramics, etc., the complex mechanical properties of their materials. Based on pure elastic mechanics, viscous theory or plasticity theory. Can not meet the deformation requirements of these materials processing process. Therefore, a research topic based on the mechanical properties of complex media, rheological theory, mentions the agenda of human new discipline research. In 1928, the United States established the "Rheology Society". In 1940, the British established the Rheology Club (later changed to the Rheology Society). In addition, the Netherlands, West Germany, France, Japan and other countries have also established a rheological society. The International Rheology Society was held in 1948. In 1953, the International Rheology Association was established. Since then. An interdisciplinary subject involving applied mathematics, physics, elastic mechanics, materials mechanics, fluid mechanics, geology, engineering, and other disciplines - rheology emerged as the times require, and gradually became widely used. Rheology is widely used not only in industrial production such as rubber, plastics, paints, printing, silicates, food, etc., but also in many industrial sectors such as capital construction, machinery, transportation, water conservancy, and chemical industry: many substances are involved. The process of solid to liquid change. Rheology is in the rubber industry. Widely used in the research and application of rubber products processing and molding. Such as rubber mixing, calendering, extrusion, injection molding and other processing. Due to its macromolecular chain structure and motion characteristics, the polymer exhibits four physical states in the physical aggregation state: one crystalline state and three amorphous states (glassy state, high elastic state, viscous flow state). . Rubber is highly elastic under normal use. In the process of forming and forming, it is a viscous flow state, and only after the vulcanization treatment, the fluidity is substantially lost, and the elastomer material is mainly composed of high elasticity.
3. Since the end of the 19th century and the beginning of the 20th century, the principle of rubber technology theory was explored and invented. Especially the research and application of rheological 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 was not only famous, but its structure, specifications, varieties, etc. all reached a certain level of scale, refinement, automation and linkage. If any rubber mechanical transmission power reaches hundreds of dry watts to thousands of kilowatts. The weight of the machine reaches several hundred tons. In the six processes of mastication, mixing, calendering, extrusion, forming and vulcanization in the production of rubber products. All have a complete set of mechanical devices. Rubber mixing machinery is one of the basic equipment of the rubber industry. There are dozens of open rubber mixing machines currently produced. It is mainly used for the plasticization of raw rubber and the compounding of rubber compound; the tableting machine is used for tableting and glue supply: the heat mixer is mainly used for preheating and glue supply of rubber materials: the crusher is used for crushing natural rubber, etc. The rubber washing machine is used to remove impurities in raw rubber and waste rubber: the crusher is mainly used for crushing waste rubber blocks: the rubber injection machine is mainly used to remove hard impurities in the reclaimed rubber; the reclaimed rubber mixer is mainly used for regeneration. Kneading of glue: cigarette glue tableting machine is used for tableting of tobacco film; etc.; tableting tableting machine is mainly used for sheeting pressing: experimental rubber mixing machine. Mainly used for experimental work of various small amounts of rubber.
