钢化膜塑面模板的铺板和预压

塑面模板的组成原理木材具有各向异性。这种各向异性主要表现在木材的收缩和膨胀中,并且各种物理机械性能在各个方面都大不相同。干缩和膨胀:当新采伐的木材完全干燥(干燥)时,沿木纹方向的收缩为0.1%至0.3%,径向收缩为3%至6%,和弦收缩为6%至12 %。机械性能仅取决于抗拉强度,沿晶粒的方向约为横向晶粒的20倍。为了使胶合板具有更好的特性,胶合板成型后就不能将木材的内在缺陷整体反映出来。当胶合板由胶合板组成时,应遵循以下原则:

(1)DUICHENGYUANLI

对称原理要求覆塑模板中心对称平面两侧的单板彼此对应,而与树木种类,单板厚度,层数,制造方法,纤维方向和水分含量无关。胶合板具有均质层(单板各层的厚度相同)和异质层(单板各层的厚度不同)。对于异质层,相应层和贴面的厚度必须相同;对于具有混合树种的胶合板,相应层的树种通常应相同。

-YINGBIAN(YUDANZHANGZHILEIXING,XIANWEIFANGXIANGDENGYOUGUAN)= L / L。

从上式可以看出,弹性模量不同,应力不同;应变不同,应力也不同。如果不满足对称原理,则对称中心平面两侧的单板饰面树的树种,厚度,层数,制造方法,纤维方向和含水量会有一定的差异,这将导致单板在对称中心平面两侧的应力不同。相等,尤其是当胶合板的含水量变化时,应力差甚至更大,这将导致诸如胶合板变形和破裂的缺陷。当满足对称原理时,胶合板中心平面两侧相应层在不同方向上的应力相同。当胶合板的开水率变化时,各层的应力变化,但相应层的应力变化相等。因此,其结构稳定并且不会产生诸如变形和破裂的缺陷。因此,对称性原则已成为所有塑面建筑模板产品必须遵守的基本原则。

(2)QISHUCENGYUANLI

当胶合板受到应力时,它常常以弯曲的形式出现。弯曲过程中水平剪切应力在其内部的分布表明,水平剪切应力的值分布在中心层的平面上。如果是偶数胶合板,则它也符合对称原理,但是偶数层的中心对称平面在胶层上。一般来说,胶层比较脆,弹性和可塑性不如木材,水平切应力。该层剥离,这降低了胶合板的粘合强度。此外,偶数胶合板必须符合对称原理。单板中间两个相邻层的纤维方向必须相同。这种结构相当于厚芯的三层胶合板。这种结构不会改善木板的性能,而只会增加木板,工作时间和粘合剂的消耗。如果遵循奇数层原理,则的水平剪切应力分布在中间层芯板上,从而避免了由偶数层结构引起的缺陷。

过去,也提出了层厚的原理,这意味着对于相同厚度的胶合板,单板越薄,层数越多,胶合板的垂直和水平强度差就越小,并且平衡了物理和机械性能。但是,在实际生产中,单板的厚度是有限的。另外,使用非常薄的胶合板制造覆塑建筑模板会导致生产过程过于复杂,降低生产率,增加原材料消耗,并增加成本。因此,不再提倡层厚原理。在实际生产中,应根据产品用途选择合适的贴面厚度。

胶合板通常不干燥,而是一些特殊的胶合板,表面层变为普通胶合板,或者胶合板的水分含量过高,胶合板燥。为了干燥胶合单板,胶中的水分应在胶中的水分渗透到单板之前迅速排出。否则,太多的水分会渗入胶合板,并且木板表面上的胶水量会减少,这会降低粘合强度。
