    • PURPOSE: Provided is a process for producing paste containing aluminum powder, which the cost of production is low by using scrap being byproduct of aluminum foil as source material of ball milling. CONSTITUTION: The process contains; i) cutting aluminum foil into scrap of ball size or less; ii) injecting a cut foil scrap, ball and 50-600wt%(based on the foil scrap) of mineral sprit in a ball milling vessel and adding 1-4.5% of unsaturated fatty acid such as oleic acid; iii) preparing platy aluminum powder paste intermediate by ball milling it in the milling vessel; and then iv) preparing a final platy aluminum powder by controlling amount of solvent after vacuum drying and filtering it. The paste is composed of aluminium powder of not less than 60wt%.
    • 目的:提供一种通过使用作为球磨原料的铝箔副产物的废料生产含铝粉末的方法,其生产成本低。 规定:该过程包含; i)将铝箔切割成小尺寸的废料; ii)在球磨容器中注入切割的箔废料,球和50-600重量%(基于箔屑)的矿物原料,并加入1-4.5%的不饱和脂肪酸如油酸; iii)通过在研磨容器中将其球磨,制备中等片状铝粉末; 然后iv)通过在真空干燥和过滤之后控制溶剂量来制备最终的板状铝粉末。 该糊状物由不低于60重量%的铝粉末组成。

    • The invention relates to a method for producing surface-modified inorganic fillers or pigments having a desired grain size. Said method is characterized in that filler or pigment slurries of inorganic fillers or pigments having a given grain size are ground to the desired filler or pigment grain size in a vertical mill using polymer dispersions, previously known auxiliary grinding agents, and/or dispersing agents at an amount of 0.1 to 4.0 percent by weight (active substance) relative to the fillers or pigments, as well as grinding balls having an equivalent diameter of up to 5 mm, under the effect of pressures and shearing forces at a temperature of the grinding material of at least 50 °C, and the binding agents of the polymer dispersions are rubbed onto the fillers or pigments and are provided with a polymer coating. Also disclosed are the fillers or pigments obtained by means of the inventive method, the use thereof for producing emulsion paints, adhesives, coatings, or spreading materials for the paper industry, especially coatings or spreading materials for different segments of the paper industry, such as sheet offset, web offset, intaglio printing, cardboard, and special papers.
    • 本发明涉及一种制备具有所需粒度的表面改性无机填料或颜料的方法。 所述方法的特征在于,使用先前已知的辅助研磨剂和/或分散剂的聚合物分散体将具有给定粒度的无机填料或颜料的填料或颜料浆料在垂直研磨机中研磨成所需的填料或颜料粒度 在研磨材料的温度下,在压力和剪切力的作用下,相对于填料或颜料的量为0.1〜4.0重量%(活性物质)以及当量直径最大为5mm的研磨球 至少50℃,并将聚合物分散体的粘合剂摩擦到填料或颜料上,并提供聚合物涂层。 还公开了通过本发明方法获得的填料或颜料,其用于制造用于造纸工业的乳液漆,粘合剂,涂料或铺展材料的用途,特别是用于造纸工业不同部分的涂料或铺展材料,例如 纸张偏移,卷筒纸胶印,凹版印刷,纸板和特殊纸张。
