Surface area of the particle size is one of the most important performance of packing, packing many performance related to its surface area.
Filler surface area increases with surfactant, dispersant, surface modification agent and polar polymer adsorption or react with the filler surface.
When some resin after adding a large number of filler material in the increase of friction in the process of injection molding processing, on the one hand, reduces the thermal stability of the plastic, on the other hand accelerated wear problem happened on the equipment.
So be appropriate in the formula to increase the amount of stabilizer and lubricant.
in the resin with the right amount of reinforced material can make the plastic mechanical strength, such as impact strength, elastic modulus, rigid doubled; Can increase the dimensional stability of products at the same time, reduce shrinkage and thermal deformation. Therefore, reinforced plastics has been in the mechanical, chemical, automotive, aerospace and other fields has been applied. Looked from the development trend of the future, with the increasing of the deflationary force of reinforcing materials and filler reinforcement, the boundaries between them will become increasingly blurred.
filler particles in general with 0. 1 - 10μ M size as well. Tiny filling agent for products of mechanical properties, dimensional stability and products surface gloss and feel. But if particle size is too small scattered difficult, processing equipment dispersing ability not enough will affect the quality of the product. So choose what size of filler in the process of production, shall, according to the types of plastic processing equipment different dispersion ability, cannot treat as the same.
plastic industry's choice of packing condition is: low cost, easily dispersed in the resin, filling quantity is big, relative density is small; Does not reduce or little to lower the price of resin molding performance and products of the physical and mechanical properties, there are a wide range of modified effect; Hydrolysis resistance, heat resistance, good resistance to chemical corrosion resistance and light resistance, and solvent extraction by water; Don't affect other additives of dispersion and efficiency, adverse chemical reactions with other additives; High purity, does not contain harmful to the resin of the magazine. Demand a certain packing with the other performance is not realistic, often in the process of production according to products the main performance of the corresponding packing.
with low cost and high filling, Gao Zengqiang and efficacy is more ideal plastic packing, for this kind of material is the development direction of plastic filling, enhance the system. In the so-called functional filler is the embodiment of the development, it gives the packing new concept, the incremental, enhancement and modified unified as a whole. Fillers can be divided into organic filler and inorganic filler, inorganic filler is more commonly used. Look from exterior filling agent for more granular packing, including powder, globular, acicular, fibrous, hollow micro ball, solid beads, etc.
some of the applications of filler also gives or improve the performance of the products to specific such as dimensional stability, just think, shading sex and electrical insulation, etc. Filler after surface treatment is not only easy to mix with resin to improve processing performance, but also have some degree of enhancement effect. Therefore, filling agent production and variety development soon, widely used in all kinds of plastic products. Reinforced material is added to the plastic can significantly improve the mechanical properties of plastic products of the packing, generally for fibrous substances and its fabric, known as strengthening agent.
most granular packing is made of rocks or minerals in a different way of granular inorganic filler. Because of the broken nonuniformity, the shape of the particles generally is irregular, even some of the shape of filler particles hard to describe. Thin sheet, fibrous filler to make processing performance is poor, but a fine mechanical properties; Amorphous powder, globular, injection molding processing and excellent performance, mechanical performance worse than thin sheet and fibrous.
