聚丙烯储罐的衬胶方式

浏览量

简单扑克魔术教学视频 www.rseoz.tw   随着时代的不断发展,聚丙烯储罐这个词也越来越被人们熟知,目前,很多储罐为了便于物品的输送,在储存重油和原油的罐内设有加热器,我们的聚丙烯储罐外侧也要采取保温措施,便是它的衬胶方式。

  对于聚丙烯储罐直径小于6米或长度短于15米的部件一般采用车间衬胶。具体指部分管件、管道、悬浮液的喷淋装置、吸收塔内的其他不同小构件。工艺:车间内,部件先被铺上未硫化过的橡胶板,然后在压热硫化釜内,温度120℃-150℃、压力6巴下进行硫化。橡胶衬里大部分采用现场衬胶。现场衬胶使用在车间内预硫化的橡胶板以及自硫化的橡胶板,现场进行粘和,不过采用前者多于后者。由于丁基橡胶需要较高的硫化温度,所以一般丁基橡胶的衬胶在车间内完成。

  聚丙烯储罐的衬胶还有一个优点:就是对软弱地基要严格控制充水速率,使罐体的沉降不致太快,同时要注意罐体四周的地表土的变化,避免地基剪切破坏。

 

With the continuous development of the times, the term polypropylene tank is more and more well known. At present, many storage tanks have heaters in tanks for storing heavy oil and crude oil for the convenience of goods transportation. The insulation measures on the outside of our polypropylene tank are also adopted, that is, its lining method.
Workshop lining is generally used for parts with diameter less than 6 meters or length less than 15 meters of polypropylene tank. Specifically refers to some pipe fittings, pipelines, suspension spraying device, other different small components in absorption tower. Process: In the workshop, the parts are first covered with unvulcanized rubber sheets, and then vulcanized in the autoclave under pressure of 6 bars and temperature of 120 - 150 degrees Celsius. Rubber lining mostly uses on-site lining. Field lining is made of pre-vulcanized rubber sheets and self-vulcanized rubber sheets in the workshop, which are bonded on site, but the former is more than the latter. Because butyl rubber needs a higher vulcanization temperature, the general butyl rubber lining is completed in the workshop.
Another advantage of polypropylene tank lining is that the filling rate of soft foundation should be strictly controlled so that the settlement of the tank can not be too fast. At the same time, the change of surface soil around the tank should be noticed to avoid the shear failure of the foundation.
