在萃期松香的生产中,原料占松香成本的70%。降低成本的途径之一就是减少明子粉碎时树脂的损耗量。根据某些工厂的材料,明子粉碎工序中所出的废料约为加工明子的5—7%。而废料中的松香含量一般并不低于加工明子的松香含量。1958年元月聶依沃鲁坚工厂取废料试样进行了分析。试样是在清理旋风除尘器时取的。分析结果证明试样的松香含量都很高(21.7—25.1%);而且从组成来看,有很大部分是相当大的碎屑(1—3毫米的占57.2—73%).此外,在已经粉碎的原料中,我们还测定了大小与废料碎屑相彷彿的碎屑含量。从几次木片试样的分析结果来看,有12—22.5%的碎屑通过了筛孔为3毫米的筛子。由以上材料看,如果经常清扫分选用的下层筛,明子的损耗量会增大一倍。因而,我们提出了自明子粉碎的废料中提取松香
In the production of rosin, raw materials account for 70% of the cost of rosin. One of the ways to reduce costs is to reduce the amount of resin that is lost when the Akiko smashes. According to some factory materials, the scrap produced in the Akiko grinding process is about 5-7% of the processed Akiko. The waste of rosin content is generally not lower than the processing of Akiko rosin content. In January 1958, Nieyiweilujian Factory took waste samples for analysis. The sample is taken when cleaning the cyclone. The results of the analysis showed that the rosin content of the samples was high (21.7-25.1%), and that a large fraction of the fragments were quite large (57.2-73% for 1-3 mm) in terms of composition. In addition, In the raw material that has been pulverized, we also determine the amount of scrap that is similar in size to scrap scrap. From the analysis of several samples of wood chips, 12-22.5% of the debris passed through the sieve with a mesh size of 3 mm. From the above materials, if you often clean the sorting of the lower sieve, Akiko loss will be doubled. Therefore, we propose to extract rosin from the smashing scraps
