Activation of polyethylene granules by finely dispersed zinc

The results of experimental researches of features of mechanical activation of polyethylene granules with finely dispersed zinc in a ball mill, and also results of research of chemical copper plating of activated polyethylene granules are given. The influence of the ratio of polyethylene granules and fine zinc, the speed of rotation of the ball mill and the duration of activation, as well as the degree of loading of the components in the activation process of polyethylene granules was studied.

PECULIARITIES OF METALIZATION OF PULLED POLYETHYLENE

The results of experimental studies of the peculiarities of metallization of granular polyethylene are presented. The influence of concentration factors on the metallization process of zinc-activated polyethylene granules of brand Liten PL-10 was investigated. It is established that by changing the concentration of copper sulfate and sodium hydroxide, as well as the degree of loading of polymeric raw materials, it is possible to effectively regulate the amount of recovered copper on granules of polyethylene, and therefore the thickness of the metal layer formed on them.

THE TECHNOLOGY OF METALLIZATION OF GRANULATED POLYMER RAWMATERIALS

The high demand of polymer composite for modern technique causes the need to create new varieties of such materials. At present, the production of a wide range of fillers and polymer matrices has already been produced, which allows the use of polymer composite materials as both structural materials and special purpose materials.

Morphology of Zinc Deposited via Cementation over Magnesium Rotary Disc in ZnCl2+NH4Cl Aqueous Solutions

Zinc cementation by magnesium from ZnCl2+NH4Cl aqueous solutions has been investigated. The amount of magnesium has been established as 0.8–2.0 g per 1 g of conditioned zinc to obtain recovery degree  99 %. At low concentrations of Zn2+ ions (0.025–0.1 M ZnCl2) dispersed deposit is formed with nanoparticles of reduced metal; at high concentrations (0.25–0.5 M) coarse-crystalline and fern-shaped deposit is formed.
