positive: (以下内容全部转载自http://cosdna.com,非化学/医学专业人士不保证专业严谨性)<br>PEG-8 (聚乙二醇-8)<br>PEG聚二乙醇(Polyethylene glycol):常见的标示是PEG,成分英文结尾有xynol、ceteareth、pleth等,通常都含有这种物质。主要用作保养品中的乳化剂、保湿剂,聚二乙醇(PEG)类的化学成分通常以数字作为不同类型区分,如:PEG-4、PEG-100等等,数字愈小,代表化学成分愈容易被皮肤吸收。这类成分很容易被皮肤吸收,已经被证实会降低血压,成分不容易被分解、容易累积在肝脏中。
negative: <br>10. The research results showed that the DFA based polyester resin had better mechanicalperformance, the water-fast performance, rate of elongation, flexility, the performanceof biodegradation and the burning-fast performance, but the chemical solvent-fastperformance, rigidity, tensile-strength were decreased.<br>研究结果显示,二聚脂肪酸的引入,使聚酯树脂具有很好的力学性能、耐水性、断裂伸长率、柔韧性、生物降解性及耐燃性能(耐燃性能可达到GB 2408—80Ⅱ级),但也会使聚酯树脂的耐溶剂性能、硬度和拉伸强度下降。<br>11. The experimental results show that the flame retardancy of PE comes up to the GB2408-80, and the mechanical properties of PE are reduced slightly.<br>实验结果表明:加入阻燃剂的聚乙烯阻燃性可达GB2408&80标准,力学性能略有下降。<br>12. Among the methods, the Level combustion method (GB2408-80) used in epoxy resin (E-44) and perpendicular combustion method (GB5455-97) used in cotten cloth are standard methods.<br>其中用于环氧树脂(E-44)的水平燃烧试验(GB2408-80)和用于棉布的垂直燃烧实验(GB5455-97)是标准实验方法。
