聚氨酯保温钢管厂家知识:怎样鉴定聚氨酯保温管的质量
Knowledge of Polyurethane Insulation Pipe Manufacturers: How to Identify the Quality of Polyurethane Insulation Pipe
随着聚氨酯保温管的使用越来越普遍,许多伪劣聚氨酯保温管开端流向市场,爲了防止购置到伪劣聚氨酯保温管,小编明天喂奶呢引见一下如何鉴定聚氨酯保温管的质量。
With the increasing popularity of polyurethane insulating tubes, many fake and inferior polyurethane insulating tubes begin to flow to the market. In order to prevent the purchase of fake and inferior polyurethane insulating tubes, Xiaobian tomorrow's feeding cloth introduces how to identify the quality of polyurethane insulating tubes.
伪劣聚氨酯保温管表面常常有麻面景象。麻面是由于轧槽磨损严重惹起聚氨酯保温管外表不规则的凹凸不平的缺陷。由于伪劣聚氨酯保温管厂家要追求利润,常常呈现轧槽轧制超标。
The surface of fake and inferior polyurethane insulating pipes often has the appearance of hemp. The rough surface of polyurethane insulating pipe is caused by the serious wear of rolling groove. Because fake and inferior polyurethane insulation pipe manufacturers want to pursue profits, rolling grooves often exceed the standard.
伪劣聚氨酯保温管外表易发生裂纹,缘由是它的坯料是土坯,土坯气孔多,土坯在冷却的进程中由于遭到热应力的作用,发生裂痕,经过轧制后就有裂纹。
The appearance of fake and inferior polyurethane insulation pipes is prone to cracks, because its billet is adobe, Adobe has many holes, Adobe in the cooling process due to the role of thermal stress, cracks occur, after rolling cracks.

伪劣聚氨酯保温管的横筋细而低,常常呈现充不满的景象,缘由是厂家爲到达大的负公差,成品前几道的压下量偏大,铁型偏小,孔型充不满。
The fake and inferior polyurethane insulating pipes have thin and low transverse ribs, which often present a situation of unsatisfactory filling. The reason is that the manufacturer wants to reach a large negative tolerance, the reduction amount of the first several passes of the finished product is too large, the iron shape is too small, and the pass is not satisfied.
聚氨酯保温管的成分平均,冷剪机的吨位高,切头端面平滑而划一,而伪劣材由于材质差,切头端面经常会有掉肉的景象,即凹凸不平,并且无金属光泽。而且由于伪劣材厂家产品切头少,头尾会呈现大耳子。
The composition of polyurethane insulation pipe is average, the tonnage of cold shearing machine is high, and the end face of the cutting head is smooth and uniform, while the fake and inferior materials, due to poor material quality, often have the phenomenon of meat loss on the end face of the cutting head, that is, uneven, and no metallic luster. And because the products of fake and inferior wood manufacturers cut little, the head and tail will show big ears.
