中国林业科学研究院于1979年3月26—30日在江西省广昌县召开了亚硫酸造纸废液采脂技术鉴定会,参加的会议代表来自14个省(区)、市,包括75个单位,共98人。该项采脂技术是由中国林科院林化所与江西崇义县桐梓松脂林场自1976年以来共同协作进行的,经过三年连续性定点试验和两年生产性扩大试验已取得了可喜的成绩。会议期间,听取了技术报告,参观了现场,同时还交流了各地的采脂经验。通过评议讨论,于3月31日一致通过了技术鉴定书。主要的鉴定意见如下:1.造纸废液可用于马尾松各种年限采脂,特别是中长期化学采脂。生产性试验证明,在一般条件下废液采脂可使松脂增产30%左右,劳动生产率提高27%左右,且操作
The Chinese Academy of Forestry held a appraisal meeting of the sulfite waste papermaking technology in Guangchang County, Jiangxi Province on March 26-30, 1979. Representatives from 14 provinces, autonomous regions and municipalities, including 75 Unit, a total of 98 people. The technology is adopted by the Chinese Academy of Forestry Institute of Forestry and Chongyi County, Jiangxi Tongzi pine fat field since 1976, collaborative work carried out, after three years of continuous fixed-point test and two years of productive expansion test has made gratifying Score. During the meeting, listening to the technical report, visited the site, but also exchange around the greasing experience. Through comments and discussions, on March 31 unanimously adopted a technical appraisal. The main identification opinions are as follows: 1. Waste paper can be used for a variety of years Pinus massonis, especially in the long-term chemical fat. Productivity tests show that, under normal conditions, waste resin can make pine resin yield about 30%, labor productivity increased by about 27%, and the operation
