Specific plastic material for the production of large parts, such as water tanks and large-size element to draw water tank made ​​of specific plastic material

摘要

A specific plastic for the production of high density polyethylene (HDPE) extrusion by blowing large barite components into water storage tanks, has as its primary component the high density polyethylene (HDPE) impact copolymer with the addition of 2,5-3, 5%of the heavy duty non-starter in the form of fillers or nano-fillers and 1,5-3,5% the heavy duty UV stabiliser in the form of a composition of the HALS stabiliser and benzophenone derivative as a UV absorber, and, in addition, contains 1-2% of the weight of the antibacterial concentrate in the form of a silver-based composition and 1-2% of the weight of the antifungal concentrate in the form of a nanoparticle-based copper composition,as well as 1-6% the weight concentration of the flavouring substance and the polyolefin medium and 1,0-1,5% the weight of the flavouring concentrate with neutral odour. Large-scale components intended for the construction of a water tank are made of this specific plastic, with a vessel-shaped container (20) having a flow hole (21) at the top of the tank,in the centre of the pump valve (22),and the lower part of the release valve (23).
