The control of the initial tensile stress of the winding container of φ 1000 methanol synthetic column and the product quality of the synthetic column of winding steel band were presented in this paper .

介绍φ1000mm甲醇合成塔绕带式容器预 拉应力的控制和绕带的 产品质量。

It is a thermoplastic elastomer and possesses good tensile properties moisture resistance gas permeation solubility and antiskid properties thus being widely used in rubber product adhesives and modifier of asphalt .

它具有良好的 拉伸性能、耐湿性、透气性、溶解性及抗滑性，而被大量用于橡胶 制品、粘合剂及沥青和树脂的改性剂等。

After heat treatment the tensile strength is 306.9 MPa the elongation percentage and the product of strength and plasticity reaches 10.9 % and 3357.6 respectively .

试样变形后经热处理，其强度提高到 306.9MPa，伸长率可以达到10.9%，强塑积达到3357.6。

The tensile strength of the recycled polyurethane film is about 2-4 times higher than that of the degraded product .

再生聚氨酯薄膜的 力学 性能与降解 产物 的 力学性能相比， 断裂 强度提高了2-4倍。

Therefore the enterprises have to improve production technology the expansion of production capacity to the integration of upstream and downstream direction of development and constantly develop downstream products tensile products chain increase product added value .

因此，各大企业纷纷改进生产工艺、扩大生产能力，向上下游一体化方向发展，并且不断开发下游产品， 拉伸产品链条，增加 产品附加值。

Determination of the melt index tensile yield strength and cleaness of the product to which the compounded agent was applied and comparisons between the above mentioned indexes and those of products of superior grade were also made .

测试复配剂（DF－5）应用 产品的熔体指数、 拉伸屈服强度、清洁度等各项质量指标与优级品指标比较。

When the amount of PGTE in the E-51 / Polymercaptan system is 30 pbw the tensile strength and the tear strength is increased 116 % and 126 % separately without substantial decrease of the curing rate and thermal stability of the cured product .

当PGTE加入量为30（ pbw）时，室温快速固化特性和固化 物的耐热性基本不变，铁片粘接的剪切强度与不均匀扯离强度则分别提高了116%和126%。

Through analyzed and test confirmed that hydrostatic extrusion can not only raise the density and tensile strength of metal that can also still raise plasticity of it 's product and twine character .

通过分析测试，证实静液挤压不仅能够提高被加工材料的塑性，而且还可以提高 产品 的 抗拉强度、密度和可缠绕性。

The results showed that the tensile strength decreased slightly the tear strength increased and the better processibility was obtained with IR partly replacing NR in the compounds ; the properties of semi product and the performance of finished product met the requirements in the relevant national standards ;

结果表明，用IR部分替代NR后胶料的 拉伸性能略有降低，撕裂性能提高，轮胎半 成品和成品性能满足相应国家标准的要求，工艺性能良好。
