Under greater stress, in the event of a molecular chain rupture, and plastic processing reinforced material can be closely combined with other chain reinforcement effect without endangering the whole quickly.
Of polymer after adding reinforced material, viscosity, thereby increasing the internal friction.
When materials by external force, the internal friction to absorb more energy, which can increase the tear resistance, wear resistance performance.
further reduction of nanometer calcium carbonate particle size range, the surface free energy will be obviously improved and enhanced performance. Particle size in 5 - Distribution of 15 nm nano calcium carbonate, and its effect is similar to white carbon black. Nanometer calcium carbonate in plastic material has a good enhanced toughness properties, good thermal stability and dispersion, can significantly improve the rigidity, bending strength, tensile strength, impact strength and scratch resistance.
to increase the intermolecular forces can choose polar materials, increase the natural dipole and the induced dipole. In the case of material must be, should try to increase the contact area of reinforced material and polymer to make materials and polymer molecular inter-atomic forces better play. Only two good affinity, can be enhanced. Due to the increase in combination with the federation between materials and polymer materials, if a molecular chain in polymer material under stress, stress can be passed out through the overseas point spread, so as to avoid material damage.
rheology, nano calcium carbonate can improve processing system to reduce the shrinkage rate, improve dimensional stability of the product, the product surface is fine, good gloss. In white plastic products can replace titanium dioxide by about 20%, reduce production cost, improve the economic effect. The nano calcium carbonate in PVC, PE, PP, ABS, PA, such as resin has a wide range of applications. Compared with ordinary calcium carbonate, nano calcium carbonate powder to make it better and ultrafine resin compatibility, realized the possibility of high fill in products, can replace part of the packing is extremely expensive his assistant, reducing the amount of resin, thereby reducing product cost and enhance the effect of the quality of products.
success of nanometer calcium carbonate filling amount of calcium carbonate in plastic tubing from 30% to 60%, will add calcium carbonate scale in the plastic packaging materials by less than 12% to 30% or more; Performance of nanometer calcium carbonate in the plastic tubes and profiles of filling quantity of more than 50%, so that the cost of plastic products has fallen dramatically. In addition to the applied to the plastic material, nano calcium carbonate in rubber, paper making, printing ink industries have a wide range of applications.
nano calcium carbonate particle morphology for the cube shape, part of the link chain, light calcium carbonate with spindle and different rules of heavy calcium carbonate. Nanometer calcium carbonate after surface activation treatment, activation rate is higher, has different functional in the matrix resin. Surface is very strong polarity of nanometer calcium carbonate calcium and carbonate ions, there is a very high surface free energy, especially the surface flaws of calcium ion in plastic material application system, and some functional groups of plastic coordination effect, strong coordination bond formation, these are the nano calcium carbonate can have good reinforced effect in plastic theory basis.
reinforced material in plastic, the most important role is to improve the mechanical strength, which increases. About the mechanism of enhancement effect is still not a unified theory. Reinforced materials in the polymer materials, can through force or chemical bonding force between the molecules and polymer materials, the combination of its own special properties and the basic properties of the polymer blend. In the injection molding processing reinforced material and reaction of polymer in combination with each other, although chemical bonding force is very big, but form chemical bonds degree is not high, and mainly intermolecular forces.
