It is understood that the modified PP (polypropylene) with 20% hollow microspheres has a notched impact strength increased by 80% to 100% compared with pure PP, and the tensile modulus and bending modulus are increased by more than 50%. The strength has also increased, and only the tensile strength has remained essentially unchanged or has dropped slightly. Ultrafine hollow microspheres are inorganic materials and have better wear resistance than polypropylene. In addition, it has a reflective effect on UV rays and can improve the UV resistance of composite materials.
According to reports, the use of ultra-fine hollow microspheres in fly ash modified polymers, on the one hand can play the characteristics of hollow microspheres, so that the mechanical properties of the polymer, wear resistance, heat insulation, insulation properties, etc. have been greatly improved. Get high performance polymer new materials. On the other hand, the masterbatch made of such modified ultrafine hollow microbeads suitable for polypropylene or polyethylene can greatly improve the mechanical properties, wear resistance, and heat insulation properties of the products through blending and addition. Reducing material costs is very suitable for injection molding products where the material has high rigidity and toughness requirements.
Activated Carbon Regeneration Rotary Furnace
In 1985, China National Gold Group Corporation was approved by theNational Economic Council,it decided
to introduce foreign advanced technology and equipment to conduct a technological reformation in Tongguan and Zhangjiakou gold mine. United States daiweimaiji company was responsible for the basic design, Changchun Gold Research Institute provided the technical support , introduced the first set electric-heated rotary kiln Activated Carbon Regeneration furnaces of gold industry in China.
In May of 1987 ,it was put into operation, and also has carried on the digestion of technology and domestic equipment reservation.In 2002 , we started to develop JHR-O series fuel oil heated active carbon regenerating furnace, August of 2004, it was put into practice in Zhang jiakou Gold mine of Hebei.In 1997 ,we also developed the JHR series electric heated active carbon regenerating furnace,in 2007, technology was upgraded and we also applied for patent of electrical ( gas ) heating rotary kiln for activated carbon regeneration equipments, gas prices rose dramatically in 2010, JHR-E series electric heating rotary kiln for active carbon regenerating furnace became the main force again.
