在标准TAPPI大胶黏物实验中,通过测定首次筛出的5加仑(18.93L)筛出物中的微胶黏物含量,可确定微胶黏物附聚所带来的胶黏物问题的原因。这个实验方法可用来确定回收纸样(如标签纸、涂蜡OCC)在不同碎浆条件下微胶黏物的形成趋势,也可用来确定回收过程中去除大胶黏物或形成微胶黏物的不同部件的操作效率(如筛选、净化、浮选或溶气浮选槽)。大胶黏物和附聚的微胶黏物是使用同一种原浆、用相同的带有0.006in(0.15mm)筛孔的细缝筛筛选时截留在筛网上的,所以从每个样品得到的结果都具有可比性。另外还介绍了微胶黏物的加速附聚实验的初步结果。
In the standard TAPPI large gummy experiment, the gummy problem caused by the agglomeration of the micro gummy was determined by measuring the amount of gummy stickies in the first 5 gig (18.93 L) the reason. This experimental method can be used to determine the tendency of microcolloids to be recovered in different pulping conditions (eg, label, wax coated OCC) and to determine the removal of macroscopic or microcolloids during recovery Operating efficiency of different components (eg screening, purification, flotation or dissolved gas flotation cells). Large stickies and agglomerated stickies were retained on the screen using the same puree and were screened on the same slender screen with a 0.006 in (0.15 mm) mesh, so from each sample The results are comparable. In addition, the preliminary results of accelerated agglomeration experiments of micro-stickies are also introduced.
