    正确安装与调节刮刀    在涂布时,涂胶量的大小主要取决于网纹辊网穴的深浅,网穴越深涂胶量越多,网穴越浅涂胶量越少。布料复合机正确调节刮刀可以保证上胶量更加均匀,从而减少或避免气泡出现。  在实际操作过程中晒版,以用压锤法来调整刮刀压力为宜,刮刀的压力一般在200~400kPa。涂布时,如果刮刀作用在网纹辊上的压力过小,在有杂质混入时,就容易将刮刀顶起来形成缝隙上海宏景,使涂布不均匀。    由于网纹辊表面是不平滑的,如果刮刀安装的角度过大,在它高速运转时,弹性刮刀片容易发生震动或跳动,使胶液弹起来爱色丽,引起涂布量差异增大。一般刮刀与网纹辊接触点的径向夹角选择在15~30°之间。    刮刀平整,则涂布量均匀,否则,涂布量差异变大。刮刀的平整度取决于刮刀的安装方法,另外也可能与刀架槽内部或刀片、衬片上粘有杂质有关。因此现状及趋势,在安装刮刀时应先擦净衬片,然后将新刀片放在衬片后面,装入刀架槽内。旋紧刀背螺丝时,应先从刀片的中间开始逐渐往两边拧紧,并且两边要轮流拧紧。为防止刀片翘曲印后工艺,旋紧螺丝一般要经两三遍完成,一边旋紧螺丝,一边用布来夹紧刀片与衬片,并用力向外侧拉紧,这样装配完的刮刀就比较平整了。
