其它装置(根据特定需要而配套的辅助装置)
7.1涂增粘剂装置
涂增粘剂装置主要由涂胶机和干燥装置组成。
7.2加热装置
7.2.1预加热装置
纸基、布基等表面多孔的基材容易吸湿,会降低复合强度,固在挤出复合之前,应将基材预热,烘除潮气,以提高复合强度。
7.2.2后加热装置
对复合后的复合材料进行再加热处理,可以适当增加粘合强度,消除复合过程中产生的应力,后加热装置通常采用电阻加热器。
7.3电晕处理装置
电晕处理装置的工作原理是在高压下放电,产生电火花冲击基材表面,使表面打毛变粗糙,扩大接触面积,提高基材表面润湿张力,粘合剂或熔融薄膜易均匀渗透到基材表面,从而提高复合强度。
电晕处理除以上的物理作用外,还有化学作用。经电晕处理后,薄膜表面张力提高至38~40N/mm。
7.4紫外线照射装置
某些塑料薄膜与聚乙烯薄膜复合时,采用紫外线处理,能显著提高复合材料的粘合强度,此法较简单,易操作,既能提高复合材料的粘合强度,又可省去涂增粘剂设备。

你这个好像跟前面那部分一样的,继续翻译啊
追答Other devices (according to specific needs and supporting the auxiliary devices)
7.1 besmear viscous agent device
Tu viscous agent device is mainly by glue machine and dry device component.
7.2 heating device
7.2.1 the heating device
Paper and cloth surface porous base, the base material of easy to absorb moisture, will reduce the composite strength, solid in composite extrusion before, should will base material preheating, except moisture, in order to improve the composite density.
After 7.2.2 heating device
To compound the compound material are again after heat treatment, can increase adhesion strength, eliminate appropriate compound produces in the process of stress, usually after heating device resistance heater.
7.3 corona processing equipment
Corona processing device's working principle is placed in high voltage electricity, produce electric spark impact surface, it hit base material surface hair becomes coarse, expand the contact area, improve the substrate surface tension, wetting glue or molten film substrate surface to permeate to the uniform, so as to improve the composite strength.
Corona processing in addition to the above the physical effects, and chemistry. The corona processing, surface tension film to increase the 38 to 40 N/mm.
7.4 ultraviolet radiation device
Some plastic film and polyethylene film compound, used ultraviolet treatment, can significantly improve the bonding strength of the composite material, this method is simple, easy to operate, and can not only improve the bonding strength of the composite material, and it saves besmear viscous agent equipment.
