Detailed Product Description: | The calcined kaolin originated in the United States. Was originally designed to remove the soft kaolin organic carbon value, improve the whiteness. Later it was used this method characteristics of the kaolin processing, production performance, high-end, value is much higher than ordinary kaolin products. Greatly broadens the scope of application of the kaolin. China has abundant coal measures kaolin resources for the characteristics of the kaolin, calcined key processes is essential. Calcined kaolin main purpose is to: 1, the removal of organic carbon and other mineral impurities in order to improve the whiteness; 2, kaolin off the moisture contained in the void volume of the calcined product and the chemical reactivity of a hydroxyl group in order to improve, to improve the physical and chemical properties, meet a wide variety of application needs. The calcined kaolin processing off in addition to the structure or crystal water, the carbonaceous and other volatile substances, and becomes will kaolinite, brand name "calcined kaolin. Calcined kaolin has a high whiteness, bulk density, surface area and pore volume, oil absorption, covered and wear resistance, insulation and thermal stability characteristics, widely used in paint, paper, plastics, rubber, chemicals, medicine, environmental protection, high-grade refractory materials and other fields. Kaolin is a large amount of mineral filler in the rubber industry. Filling kaolin plastic material is easily processed, compound a smooth surface, and carbon black, which will help the dispersion of the carbon black in the rubber compound, but kaolin DPG adsorption rate effect on curing speed. Vulcanizates filled with kaolin, relatively high tensile strength, good wear resistance, but poor tear strength. The rubber filler kaolin widely used in hose, tape, pads, shoes, especially oil, acid, heat and other products. Active kaolin, the chemical modification kaolin, to improve product performance and the development of light-colored rubber products have a significant effect. ; In the wire and cable sheath, can improve its wear resistance, resistance to incision extending; insulating rubber compound, so that to obtain a stable wet electrical properties, and increase the modulus and tensile mild; pipe in in the belt, and can improve the wear resistance of the belt and increase the hot tear mild and reduce heat buildup, it can improve the solvent resistance and abrasion resistance; In the sole increase sole flexing lifetime, to improve the wear resistance can be reduced; gasket compression deformation rate. In the process, the plastic material of the mixed-period can be shortened to reduce its viscosity. Calcined kaolin as a rubber filler application prospect is very broad. Modified calcined kaolin and plastic material similar surface polarity, moist material susceptible to gum, eat faster powder can improve the dispersion effect, play a reinforcing effect, and improve the mechanical properties of the production process and product. Ordinary modified calcined kaolin in rubber, can play a semi-reinforcing effect, and is conducive to spread and exchange; the vulcanization efficiency is a significant improvement, also improved its processing performance and increasing the filler content, is conducive to reduce costs. Calcined kaolin treated by a special method, greatly increasing the specific surface area, and then subjected to surface treatment, in the rubber reinforcing effect can be improved, and some can even reach the vapor-phase carbon black or carbon black precipitate effect. |
