摘要

摘要废纸作为一种原料，其使用量日益增加，由于其含有不同来源的非纤维物质，因此具有异质结构。它是希望有一个均匀的产品时，回收。在本研究范围内，对按en643标准测定的原料和回收利用这些原料制成的产品的SEM图像进行了检查，说明了灰分含量、细粒含量和筛上灰分，并讨论了测定填料含量(去除)和纤维细粒(去除)的结果。灰分含量最高的是H3和U3，最低的是H6和U9。结果表明，细粒含量最高的样品是H2和U1，含量最低的样品是H4和U2。筛上灰分最高的是H3和U3，最小的是H2和U9。填料含量在H1和U3样品中最高，在H6和U9样品中最低。细纤维含量最高的是H2和U9，最少的是H1和U3。

Determination of fines in recycled paper

Abstract Waste paper, the use of which is increasing day by day as a raw material, has a heterogeneous structure as it contains non-fiber material from different sources. It is desired to have a homogeneous product when recycled. Within the scope of this study, the SEM images of the raw materials determined according to EN 643 standard and the products made with the recycling of these raw materials were examined, ash content, fines content and ash on sieve were stated and the results obtained by determining filler content (removed) and fiber fines (removed) were discussed. While the samples with the highest ash content were H3 and U3, the lowest samples were H6 and U9. It was determined that the samples with the highest fines content were H2 and U1, while the lowest samples were H4 and U2. While the samples with the highest ash on sieve were H3 and U3, the samples with the least were determined as H2 and U9. The filler content was highest in H1 and U3 samples, while the lowest was in H6 and U9 samples. The samples with the most fiber fines were found as H2 and U9, and the least as H1 and U3 samples.
