怎么辨别ppr管材的优劣?

作者: admin    来源:http://www.laobingguandao.com  时间:2020-01-31    人气:
1、一般优质的ppr管材,受到挤压不容易变形,就算变形也不会破裂,这样便会减少接头的使用量。劣质管材,用手捏,或者使用其它方法,容易变形。
1. Generally, high-quality PPR pipes are not easy to be deformed by extrusion, even if they are deformed, they will not crack, which will reduce the use of joints. Poor quality pipes are easy to deform by hand or other methods.
2、质量上等的ppr管材,它的管件放老化比较强,使用寿命比较长,在正常使用的情况下,可以达到50年以上。
2. PPR pipes of high quality have strong aging and long service life, which can reach more than 50 years in normal use.
3、ppr管件在常温下能够承受水压力为45千克/平方厘米,管子能够承受的不变形高温,是112℃,它具有较强的耐高温及耐高压性。劣质的管材表面颗粒较为粗糙,会散发异味,也达不到这样的温度。
3. PPR pipe can bear water pressure of 45 kg / cm2 at room temperature, and the pipe can bear high temperature without deformation, which is 112 ℃, it has strong high temperature and high pressure resistance. The surface particles of inferior pipes are rough, which will give off peculiar smell and can not reach such temperature.HDPE通用增强网状结构壁管
 
4、判断管材优劣,还可以通过火烧的方法,一般如果原料中混合了回收塑料,在燃烧时,会散发出难闻的气味,会冒黑烟。优质的ppr管,则不会出现这样的情况。
4. Generally, if recycled plastics are mixed in the raw materials, when they are burned, they will emit unpleasant smell and black smoke. This is not the case with high quality PPR tubes.
