聚丙烯纤维与玻璃纤维有哪些区别
聚丙烯纤维与玻璃纤维有哪些区别
What are the differences between polypropylene fibers and glass fibers
聚丙烯纤维是一种合成纤维由聚丙烯或丙烯共聚物制成的。第二单体为非离子型单体如丙烯酸甲酯、甲基丙烯酸甲酯等，第三单体为离子型单体如丙烯磺酸钠和2-亚甲基-14-丁二酸等。
Polypropylene fibers are synthetic fibers made from polypropylene or propylene copolymers. The second monomer is non-ionic monomer such as methyl acrylate, methyl methacrylate, etc. The third monomer is ionic monomer such as sodium allylsulfonate and 2-methylene-14-succinic acid.
性能特点：聚丙烯纤维具有高抗拉强度、良好的吸油性及亲水性、耐高温、不溶胀、吸附性强、化学性质稳定等特点，因性能极似羊毛弹性较好伸长20%时回弹率仍可保持纶化学分子式 65%，蓬松卷曲而柔软保暖性比羊毛高15%所以又有合成羊毛之称。
Performance characteristics: Polypropylene fiber has high tensile strength, good oil absorption and hydrophilicity, high temperature resistance, non-swelling, strong adsorption, chemical stability, etc. Because its performance is very similar to that of wool, when its elasticity is better than 20% elongation, the resilience of polypropylene fiber can still maintain 65% of its chemical formula, and its soft curling and warmth retention is 15% higher than that of wool. Also known as synthetic wool.
在水泥混凝土的掺量：通常情况，砂浆、混凝土掺入0.6~1.0kg/m3；如工程对混凝土抗裂、防渗、耐磨要求高，可根据砂料、石料、水泥用量的变化，适当调整聚丙烯纤维的掺量，但最高为1.5kg/m3；不同的集料颗粒级配对混凝土性能影响很大所以尽可能选择优良的级配。
The dosage of polypropylene fiber in cement concrete: usually 0.6-1.0kg/m3 is added to mortar and concrete; if the requirement for crack resistance, impermeability and wear resistance of concrete is high in engineering, the dosage of polypropylene fiber can be adjusted according to the change of the dosage of sand, stone and cement, but the maximum is 1.5kg/m3; the performance of concrete can be adjusted by different aggregate particle gradation. It has a great influence, so choose the best gradation as far as possible.
聚丙烯纤维也叫纶纤维，因具有高抗拉强度、良好的吸油性及亲水性、耐高温、不溶胀、吸附性强、化学性质稳定等特点，不仅可以用于砂浆、水泥混凝土中也可以用于沥青混凝土。
Polypropylene fibers are also called fibers, because of their high tensile strength, good oil absorption and hydrophilicity, high temperature resistance, non-swelling, strong adsorption and chemical stability, they can be used not only in mortar and cement concrete, but also in asphalt concrete.
在建筑工程中有些纤维添加在混泥土中可以改善其的性质，如玻璃纤维和聚丙烯纤维；玻璃纤维是一种无机非金属材料而聚丙烯纤维是一种合成纤维。那么在性能方面这两者有什么不一样呢。
In construction engineering, some fibers can be added to concrete to improve its properties, such as glass fibers and polypropylene fibers; glass fibers are inorganic non-metallic materials and polypropylene fibers are synthetic fibers. So what's the difference between the two in terms of performance?
