What is the difference between mixer and kneader

The internal mixer is a high-strength intermittent mixing equipment developed on the basis of the open mixer. Since the emergence of the real Banbury (Benbury) type internal mixer in 1916, the power of the internal mixer has been gradually recognized by people. It shows a series of characteristics superior to the open mixer in the rubber mixing process, such as: large mixing capacity, short mixing time and high production efficiency; Better overcome dust flying, reduce the loss of compounding agent, improve product quality and working environment; Safe and convenient operation, reduce labor intensity; it is beneficial to realize mechanical and automatic operation, etc. Therefore, the emergence of the mixer is an important achievement of rubber machinery, and it is still a typical important equipment for plasticizing and mixing species, and it is constantly developing and improving. What is the difference between an internal mixer and a kneader, and what are the differences in product applications between them? Kneader is by a pair of mutual cooperation and rotation of the blade (usually Z-shaped) produced by a strong shear effect to make the semi-dry state or rubber-like viscous plastic material can make the material react quickly to obtain uniform mixing and stirring equipment. It is an ideal equipment for mixing, kneading, crushing, dispersing and re-polymerizing various chemical products of various high-viscosity elastic-plastic materials. It has the advantages of uniform stirring, no dead angle and high kneading efficiency. It is widely used in high-viscosity sealant, silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, battery, ink, pigment, dye, medicine, resin, plastic, rubber, cosmetics and other industries. What is the difference between an internal mixer and a kneader, and what are the differences in product applications between them? The kneading machine can be made into four types: ordinary type, pressure type, vacuum type and high temperature type. The temperature adjustment form adopts jacket, steam, oil heating, water cooling and other methods, and adopts hydraulic cylinder turning and cover opening. Discharging methods include hydraulic pressure, overturning cylinder dumping, ball valve discharging, screw extrusion, etc. And through the PLC real-time control and record the production of temperature, time, viscosity and other related data. Cylinder and blade and material contact parts are made of stainless steel to ensure product quality.

Rubber and plastic insulation material

In the late 1970 s, rubber and plastic insulation materials have been used in building energy conservation in some developed countries abroad. The construction industry is forced to implement energy-saving standards in new buildings to use rubber and plastic insulation materials. The application of rubber and plastic insulation materials in developed countries and the importance of building energy conservation and some measures taken have achieved great results in these countries, Building energy consumption has dropped significantly. For example, after the use of rubber and plastic insulation materials in Denmark, the heating area increased by 30% in 1985 compared with 1972, but the heating energy consumption decreased by 3.18 million tons of standard coal. Thus, the foreign building energy conservation regulations have achieved remarkable social and economic benefits for more than 30 years. Rubber-plastic thermal insulation material is an elastic closed-cell elastic material, which has excellent properties such as softness, bending resistance, cold resistance, heat resistance, flame retardant, waterproof, low thermal conductivity, shock absorption, sound absorption, etc. It can be widely used in central air conditioning, construction, chemical industry, textile industry, metallurgy, communication, vehicle, electrical appliance and other industries and some cold and hot medium pipelines and containers, and can achieve the effect of reducing cold and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, and will not breed any harmful substances such as mold, so it is a high quality cross-century new generation of thermal insulation materials. The promulgation and implementation of rubber and plastic insulation materials and products, energy-saving regulations are the influencing factors of building energy efficiency, involving a large industrial group. The development and application of building rubber and plastic insulation materials have been paid more and more attention by all countries in the world, and new rubber and plastic insulation materials are constantly emerging. From the construction of rubber and plastic insulation materials and varieties, at home and abroad to polystyrene as the main raw material of rubber and plastic insulation materials research is relatively extensive, but most of them are in the field of plate, such as polystyrene board, steel wire mesh sandwich composite inner and outer wall panels, metal composite sandwich panels. Although polystyrene board as a rubber and plastic insulation material in use has a good thermal insulation effect, but due to the characteristics of the plate makes the polystyrene board in the construction and the main body is connected to the point fixed, surface fixed as a supplement, between the plate to splice, bonding, not suitable for the shape of the complex building insulation, construction process is more complex, high comprehensive cost. At the same time, due to the hydrophobicity of polystyrene board and regular hydrophilic materials do not adapt, resulting in its surface layer outside the follow-up construction quality is not easy to ensure, prone to surface mortar cracking, shedding, hollowing and other quality problems, the external decoration of buildings such as brick, paint use or construction constitutes a great constraint. The amorphous slurry rubber and plastic insulation material can overcome these shortcomings of the plate type, so it constitutes an important part of the building thermal insulation material. Europe and the United States and other developed countries in the research and application of slurry rubber insulation materials started earlier, the technology is more mature, in the research and application has been fruitful. In the research and development of rubber and plastic insulation material slurry, at present, the developed countries are mainly light multi-functional composite slurry rubber and plastic insulation materials. The performance of this kind of slurry rubber insulation material is obviously improved compared with the traditional slurry rubber insulation material, such as low thermal conductivity and good use safety and durability. At the same time, this kind of composite slurry rubber and plastic insulation material has excellent functionality, such as non-freon flame retardant polyurethane foam composite slurry rubber and plastic insulation material, all hydrophobic calcium silicate slurry rubber and plastic insulation material, etc., can meet the requirements of different use conditions. Rubber and plastic insulation materials industry environmental protection issues, foreign countries also attach great importance to the active development of "green" rubber and plastic insulation materials products, from raw material preparation (mining or transportation), product production and use, and future processing problems, are required to save resources and reduce the harm to the environment. The rubber and plastic insulation material industry is a very successful typical example of the recycling of foreign resources.
