Abstract

Abstract: The aging properties of plastics-coated woven bags for cement were studied by analyzing the breaking strength and elongation at break before and after ultraviolet irradiation. For the bags without anti-aging agent, the breaking strength retention rate of the bags of summer grade was 14 % after sunlight for 21 d, and that of winter grade was 48 % after sunlight for 30 d. For those containing anti-aging agent, the breaking strength retention rate of winter grade was 65 % after ultraviolet irradiation for 12 h (equivalent to sunlight for 32 d).

Key words: plastics-coated woven bag, aging property, breaking strength, elongation at break, cement
