For the Plastic Modified Precipitation Barium Sulfate Advantages

Author:Jinlin corundumTo update: 2016-10-13

See this title, you will feel very strange bar, after all, barium sulfate this product in our life to see the number of times, it is not like garnet, emery products like that in our lives is very common, so for our company today to be described for the plastic modified precipitation of barium sulfate advantage you may be more unfamiliar, but please follow our footsteps, to learn together.
Plastic filled with modified plastics filler, and resin, composite filler, usually filler larger, so the filler is the plastic industry important, no lack of auxiliary materials. Perhaps you are not very familiar with the filler, but our company website describes the effect of refractory filler on the quality of casting, although the content is not a lot, but I hope you can help. Fillers as precipitated barium sulfate is also a product can not be ignored. Plastic filling modification has the following advantages:
I. Reduce costs
When we buy products, always on its price, quality comparison, like why the price of brown fused alumina is higher than black fused alumina. Usually filler than resin cheap, so the increase in filler can significantly reduce the cost of plastic, with significant economic benefits, which is widely used in plastic filler modification is the main reason.
II. Improve the heat resistance of plastics
Usually the heat resistance of plastic is low, such as ABS, its long-term use temperature as long as 60 ℃, and most fillers are inorganic substances, heat resistance is high, so these fillers added to the plastic can significantly enhance the heat resistance of plastic .
III. Improve the rigidity of plastic
Usually less rigid plastic, such as the flexural modulus of pure PP around 1000MPa, far can not meet the needs of the use of some components, an increase of 30% talc, the tortuous modulus of up to 2000MPa or more, so we can know talc with Significant increase by just effect.
IV. To improve the processing of plastic molding
Some fillers can improve the processability of plastics, such as barium sulfate, glass beads, etc., can improve the flow of resin, which can improve its processing.
V. Improve the dimensional stability of plastic products and components
Some plastic shorten the big, resulting in shortening rate of its products, from the mold out more easily after the deformation, scale instability; However, increased packing, can greatly reduce the plastic shortening, and then improve the dimensional stability of plastic products and components.

VI. Improve the appearance of plastic hardness
Inorganic filler hardness than plastic hardness, increased inorganic filler, can greatly improve the appearance of plastic hardness.
VII. Progress Strength
Universal tensile strength of the plastic itself is not high, increase the inorganic filler, the filling amount within the appropriate range, can improve the tensile strength of plastic and zigzag intensity, and then improve the engineering use of plastics.
VIII. Given some of the functions of plastic, plastic added value
Some fillers can give some of the functions of plastic, such as PP to increase talc, calcium carbonate, PP can improve the anti-static function and printing functions.
Shizui Mountain Jinlin Fused Alumina Refractories Co., Ltd. is a diversified production plant, set the development, production, sales and service in one. The company mainly produces fused alumina products, brown fused alumina, white fused alumina, silicon carbide, bauxite, alumina ball, garnet, alumina powder, zircon sand, castable and other products specializing in the production and processing company, with a complete and scientific quality management system.
In short, the plastic filling modification has many advantages, has been widely used, but also pay attention to fill the question of modified, such as: usually impact strength to reduce the density to increase the appearance of gloss to reduce the color saturation degree to reduce the fill volume is too large to greatly reduce the intensity. These defects should be fully considered in the formulation design. Can not blindly increase the amount of filling to reduce costs, taking into account the use of products and function of persistent persistence.
