Vertical grinding machine production ultra-fine filling material and surface treatment composite technique

Abstract

The invention discloses a compounding technology of producing superfine filler by a vertical roller mill and superficial treatment, comprising the following steps: firstly preparing materials, using a crusher to crush raw ore into elementary broken powder which is then transported to the vertical roller mill through a bucket elevator and a conveyer screw to sinter into superfine filler powder, then using dense phase pneumatic conveyor to transport the superfine filler powder which is then packed into an ultimate product to an ultimate product warehouse, which is characterized in that before the materials get into the vertical roller mill, surface active agent miscible liquids after hydrolyzing with content of 8% to 16% is added into the conveyer screw to mix fully. The invention enhances the dispersivity and anti-break performance of modified materials like plastics, rubber, PVC, PE, ABS, stretch-proof and anti-fracture function of the ultimate product, overcomes the problem of being hard to distribute and reunite in the process of processing, saving and applying superfine powder, and is worth to be popularized.

Description

technical field [0001] The invention relates to the technical field of non-metallic powder processing, and more specifically relates to the production of superfine fillers and surface treatment processes. Background technique [0002] At present, the production of ultrafine fillers in China is still relatively backward, especially for the ultrafine fillers produced, the phenomenon of secondary agglomeration is very serious, which seriously affects the dispersibility of fillers in plastic modification, and affects the tensile strength and tensile strength of finished products. Physical properties and chemical properties such as anti-aging and weather resistance. At present, the domestic production process of active filler is to use the ultra-fine powder after the production is completed, and then the active treatment process is carried out again. This process increases a lot of manpower and material resources, and increases the cost of electric energy. Contents of the inven...

[0002] At present, the production of ultrafine fillers in China is still relatively backward, especially for the ultrafine fillers produced, the phenomenon of secondary agglomeration is very serious, which seriously affects the dispersibility of fillers in plastic modification, and affects the tensile strength and tensile strength of finished products. Physical properties and chemical properties such as aging resistance and weather resistance

At present, the domestic production process of active filler is to use the ultrafine powder after the production is completed, and then the active treatment process is carried out again. This process increases a lot of manpower and material resources, and increases the cost of electric energy and so on.
