PE空气纤维材料耐久性能研究
Research on the Durability Performance of PE Air Fiber Materials
摘要
Abstract
This paper study studies the effect of density(60,70,80 kg/m3)and thickness(5 cm,10 cm,15 cm)of PE air fiber materials on their durability.Through mattress durability tests,the results are as follows.(1)Density has no significant effect on the thickness loss of the edge durability area.After 10,000 tests,the thickness loss rate of the samples is between 1.0％and 3.1％.(2)Density is the key factor determining the durability of the sleeping area,and an increase in density significantly reduces the thickness loss rate.High-density materials(80 kg/m3)perform excellently in all thicknesses and provide reliable support for the design of lightweight thin pads(5 cm).(3)The effect of thickness has double natures:increasing the thickness will increase the absolute deformation amount,but significantly reduces the relative loss rate,thereby improving actual durability.When the thickness is greater than or equal to 5 cm,the risk of the edge durability loss rate exceeding 10％is extremely low(it is recommended that the rigid requirements be exempted in standards);however,for thin pads with a thickness of 5 cm or less,the risk of the durability loss rate in the sleeping area(30,000 times)exceeding 10％is relatively high.It is necessary to avoid using single low-density materials or prioritize the use of 80 kg/m3 high-density core materials.(4)The hardness stability is outstanding.All samples are hard mattresses,and the indentation hardness grade changes are small(only 0.1～0.2)after durability tests,indicating a reliable material structure.关键词
