The costs of abietic acid separating with A amine salt method and B amine salt method were 1/5 and 1/3 of cost separating with di-n-amylamine salt reported in the literature respectively.

同时研究了以酸异构化、高温异构化和微波辅助酸异构化松香制备枞酸含量较高的异构化松香的实验条件，以异构化松香为原料，采用多种方法分离提纯枞酸，得到最佳分离提纯条件。

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

试验表明在以松香、重烷磺酸钠、石油磺酸钠为主要乳化剂时，要获得优良的乳化液，需满足以下几个条件：(1)需在乳化油配方中加入适量的乳化剂，且其中阴离子乳化剂总量与非离子乳化剂总量的应保持适当的比例；(2)乳化油中环烷酸锌的量与其它乳化剂总量要保持正比关系；(3)乳化油中松香的量不易过大，且油酸的加入量应与松香量成正比；(4)乳化油中水分含量不易过高(一般不能大于8％)，过高时稳定性不好，易分层。

Flux tank: Adopt stainless steel, oil heating to enable the flux temperature invariableness.

松香桶：采用不锈钢内胆，油温加热方式，可恒定松香的温度。

The general ideas of this paper is to prepare polymercomposite emulsions of modified rosins and acrylates with mini-emulsion polymerizationmethod, and to discover the relations between their preparation, structure and properties, andfinally to provide theoretical basis to the deep utilization of rosin and to the development ofnew polymer materials from natural renewable resources.

论文的总体思路是采用细乳液聚合手段，创新开发改性松香／丙烯酸酯复合高分子乳液，并揭示其制备、结构和性能的关系，为松香的深加工利用以及用天然可再生资源开发高分子新材料提供理论依据。

After brushing bamboo with slushing compound and melted petroleum asphalt, the percentages of water-absorption of bamboo are 6.1% and 3.8%, respectively, after immersion in watertfor seven days.

用沥青液及熔化的石油沥青分别涂刷竹材，浸水七天后竹材的吸水量各为6.1％及3.8％，若用松香的酒精溶液涂布竹材，其防水效力不大，并且和松香的浓度不成正比的关系。

By analyzing the situation of producing and selling of Chinese gum rosin ,the development of Chinese gum rosin industry can be divided into three main stages.

通过对20世纪90年代以来中国松香产销情况的分析，把中国松香行业的发展分为3个主要的发展阶段，并由此引出未来中国松香行业发展的趋势：松香生产必将逐步与松林基地结合，实现&林脂一体化&；热熔松香将在松香深加工过程中广泛采用；松香的国内需求将随着松香深加工产业的发展而迅速扩大。
