摘要： Method of incorporation a talcum powder into a material, in particular a thermoplastic material. The method consists in (a) mixing the talcum powder with water and a polyethylene glycol, a polypropylene glycol or a copolymer of these compounds, (b) pressing the mixture through dies and sectioning it to obtain granules of an average size exceeding that of the grains of the initial powder, (c) incorporating in the material the product obtained, (d) subjecting the dispersion to mechanical action to break up the granules and to release and distribute in the mass the grains of the initial powder. The invention is characterized by incorporating small particle-sized talcum powders into materials, especially thermoplastic materials, without the practical problem involved in incorporating small particle-sized powders.

摘要： A process for treating a lamella-type mineral in the form of particles constituted of stacks of sheets, in order to obtain a functional filler for a polymer material. The mineral is suspended in a liquid with a predetermined initial particle size, after which the suspension is subjected to a delamination procedure in order to separate the sheet from the particles, and obtain a particle size smaller than the initial particle size. The suspension is then subjected to selection in order to eliminate the particles larger in size than the predetermined size; it is subsequently dried, and the mineral particles are treated so as to restrict the creation amongst them of strong irreversible bonds. The talcum powder obtained can be incorporated into a thermoplastic material as a functional filler in order to increase the flexural modulus in proportions significantly higher than what is obtained with known fillers, without diminishing the shock resistance of the final material (with respect to the values obtained with said known fillers).
摘要翻译：为了获得聚合物材料的功能性填料，用于处理由片状堆叠构成的颗粒形式的薄片型矿物的方法。将矿物悬浮在具有预定初始粒度的液体中，之后将悬浮液进行分层操作以将片材与颗粒分离，并获得小于初始粒度的粒度。然后对悬浮液进行选择以消除尺寸大于预定尺寸的颗粒; 随后干燥，并处理矿物颗粒以限制它们之间的强不可逆键的产生。所获得的滑石粉可以作为功能性填料掺入到热塑性材料中，以增加比例显着高于用已知填料获得的弯曲模量，而不会降低最终材料的抗冲击性（相对于获得的值）与所述已知的填料）。

摘要： A reinforced composite tubular body comprises a metallic reinforcement of helical convolutions completely embedded in a tubular body of thermosetting polymer which has a coefficient of elongation at rupture less than 15%. The reinforcement comprises at least one metallic reinforcing strip wound helically around the longitudinal axis of the tubular body so as to form a plurality of successive helical convolutions completely embedded in the wall thickness of the tubular body and separated from one another by the polymeric material. The extent of overlap of adjacent helical convolutions is at least equal to e.multidot..sigma..sub.r /2.tau. where e designates the thickness of the strip, .sigma..sub.r the ultimate breaking strength of the strip and .tau. the shear strength of the metallic strip/polymeric material interface. Fillers may be incorporated in the tubular polymeric material to reduce the amount needed of the more expensive polymeric material and/or to impart other desired properties to the reinforced composite tubular body.
