The results of decorative coatings of 'crystallite' type on metallic and non-metallic surfaces are presented in this work. We propose the low-temperature chemical method that allows receiving the "crystallite" pattern with a preliminary assessment of decorative coating quality on all, including non-metallic materials. For this, at first a product is dipped for a few seconds into the saturated solution of copper salt at the temperature of 80-90 ºC for metals and 60 ºC for polymeric materials. At drying the product on air "crystallite" type patterns are formed onto its surface. If poor quality pattern is received, then it is easily washed off with water, thereupon repeating previous operations the qualitative patterns can be obtained. To fix the received in such way patterns of the product they are treated by gas, containing phosphine.
The regulating of a structure and a pores volume of activated carbons by mechanical, chemical and thermal activations of agricultural wastes, such as apricot kernel shells were studied. The mechanical activation was provided in the grinding mill, in the aqueous medium. The chemical activation was implemented by treatment with sulfuric, hydrochloric, phosphoric acids at the concentrations of 5%-40% and by zinc chloride at the penetration coefficients of 0.1÷0.6. The thermal activation was effected in carbon dioxide atmosphere at the temperatures of 300÷100 о С. It was researched an influence of acid concentration, ZnCl 2 coefficient of impregnating, CO 2 temperature per volume of micro-, meso-and macropores. Activated carbons have arranged porous structures in the following line: processed by ZnCl 2 and CO 2 > processed by ZnCl 2 > processed by H 2 SO 4 > processed by H 3 PO 4 . For the samples are treated by ZnCl 2 and subsequent CO 2 , the activation optimal parameters are following: temperature of CO 2 =500 о С; the penetration coefficient = 0.4.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
