聚对苯二甲酸乙二醇酯 杨氏模量和泊松比
标题:聚对苯二甲酸乙二醇酯的杨氏模量和泊松比一、概述聚对苯二甲酸乙二醇酯(简称PET)是一种常见的聚酯类塑料,具有良好的物理性能和化学稳定性,因此在工业生产和日常生活中被广泛应用。
PET的力学性能是评价其工程应用价值的重要指标,其中杨氏模量和泊松比是两个关键参数。
二、杨氏模量的定义和测定1. 杨氏模量(Young's modulus)是材料在弹性阶段内应力和应变之间的比值,用于描述材料的刚度和弹性变形性能。
2. 测定PET的杨氏模量通常采用拉伸试验,将试样置于拉伸试验机上,在一定的载荷作用下测定其应变和应力,由斜率即可得到杨氏模量。
三、PET的杨氏模量特点1. PET的杨氏模量与温度、拉伸速率、拉伸方向等因素有关,一般情况下,PET的杨氏模量在1000-4000 MPa之间。
2. PET的杨氏模量随着温度的升高而下降,这是由于高温下分子间作用力减弱,分子链的运动增加导致的。
3. PET的杨氏模量受到结晶度的影响,结晶度越高,杨氏模量越大。
四、泊松比的定义和测定1. 泊松比(Poisson's ratio)是材料在拉伸或压缩时横向应变与纵向应变之比,用于描述材料的各向同性和非均匀变形性能。
2. 测定PET的泊松比可以采用压缩试验或剪切试验,通过测定材料在不同载荷下的应变与应力关系即可确定泊松比。
五、PET的泊松比特点1. PET的泊松比通常在0.3-0.4之间,具有一定的各向同性。
2. PET的泊松比受温度和应变速率的影响较小,相对稳定。
3. PET的泊松比在拉伸和压缩情况下略有差异,但一般情况下可以忽略不计。
结论PET作为一种常见的聚酯类塑料,具有一定的杨氏模量和泊松比。
了解和掌握PET的杨氏模量和泊松比对于评估其在工程领域的应用具有重要意义。
希望通过本文的介绍,能够增加大家对PET材料力学性能的了解,促进PET材料在工程领域的更广泛应用。
六、PET的杨氏模量与工程应用1. PET广泛应用于纺织、包装、电子、汽车等领域,其杨氏模量的特性对这些领域的工程应用具有重要意义。
500l-z钢卷成分
500l-z钢卷成分
500l-z钢卷是一种常见的冷轧热处理钢卷,其成分主要包括以下几个方面:
1. 碳含量(C):通常在0.12%至0.20%之间,控制碳含量可以调节钢的强度和硬度。
2. 锰含量(Mn):通常在1.00%至1.70%之间,锰对于提高钢的强度有很大的影响。
3. 硅含量(Si):通常在0.20%至0.50%之间,硅可以提高钢的抗腐蚀性能和加工可塑性。
4. 磷含量(P)和硫含量(S):这两个元素的含量应尽可能低,因为它们会对钢的焊接性能和韧性产生负面影响。
5. 铬含量(Cr)和铜含量(Cu):这些合金元素的含量较低,通常不超过0.30%,用于提高钢的耐候性和耐蚀性。
以上是500l-z钢卷的一般成分范围,具体的成分比例可能会因生产厂家和使用要求而有所不同。

高分子聚合物资料
聚对苯二甲酸乙二醇酯化学式为-[OCH2-CH2OCOC6H4CO]-英文名: polyethylene terephthalate,简称PET,为高聚合物,由对苯二甲酸乙二醇酯发生脱水缩合反应而来。
对苯二甲酸乙二醇酯是由对苯二甲酸和乙二醇发生酯化反应所得。
PET 是乳白色或浅黄色、高度结晶的聚合物,表面平滑有光泽。
在较宽的温度范围内具有优良的物理机械性能,长期使用温度可达120℃,电绝缘性优良,甚至在高温高频下,其电性能仍较好,但耐电晕性较差,抗蠕变性,耐疲劳性,耐摩擦性、尺寸稳定性都很好。
作为包装材料PET优点:①有良好的力学性能,冲击强度是其他薄膜的3~5倍,耐折性好。
②耐油、耐脂肪、耐稀酸、稀碱,耐大多数溶剂。
③具有优良的耐高、低温性能,可在120℃温度范围内长期使用,短期使用可耐150℃高温,可耐-70℃低温,且高、低温时对其机械性能影响很小。
④气体和水蒸气渗透率低,既有优良的阻气、水、油及异味性能。
⑤透明度高,可阻挡紫外线,光泽性好。
⑥无毒、无味,卫生安全性好,可直接用于食品包装。
PET的危害:阿联酋一个12岁的女童,因为连续16个月使用同一个矿泉水瓶,得了癌症。
研究发现,塑料瓶里面含有一种叫做PET的物质,这种物质使用一次是安全的,但如果你为了节俭或图方便而重复使用该类塑料瓶,就会受到癌症的威胁。
塑料瓶的底部都有一个带箭头的三角形,三角形里面有一个数字,以下这些塑料瓶底三角形中的数字,指代的是该瓶子包含的成分和该成分对人体健康的影响——1——PET聚对苯二甲酸乙二醇酯常见于矿泉水瓶、碳酸饮料瓶等。
温度达到70℃时易变形,且有对人体有害的物质融了。
1号塑料品使用10个月后,可能释放出致癌物DEHP。
这类瓶子不能放在汽车内晒太阳,不能装酒、油等物质。
2——HDPE高度密聚乙烯常见于白色药瓶、清洁用品、沐浴产品。
不要用来做水杯,或者做储物容器装其他物品。
3——PVC聚氯乙烯常见于雨衣、建材、塑料膜、塑料盒等。
