In paper making , chitosan can be used as fortifier , sizing agent , retention and filtration aid , surface modifier and flocculation agent for paper - making effluent 在造纸方面，壳聚糖可用做纸张增强剂、施胶剂、助留助滤剂、表面改性剂和造纸废液的絮凝剂。
She is cast off the fist ( and if i ' m not fast enough , she ' ll cast herself off ) and returns when i have sounded her conditioned reinforcer to get her reward 她摆脱了拳头（如果我不是不够快，她会投自己关闭） ，以及回报时，我已敲响了她的条件增强剂，以得到她的报酬。
A new type of sound absorbing materials mainly made from low alkaline cement and expanding pearlite has been investigated on the basis of sound absorption principle 摘要以低?水泥和膨胀珍珠岩为主要原料，辅之以分散性良好的增强剂聚丙烯纤维，研制出一种新型吸声材料。
Interestingly , the glutathione - promoting drug n - acetyl cysteine ( nac ) has been tested in experimental allergic and irritant contact dermatitis and found to reduce these reactions ( 2 ) 令人感兴趣的是， （研究2 ）使用谷胱甘肽增强剂nac来测试过敏性及刺激性接触皮炎，发现可以降低反应。
Adding assistant at optimal dosage , reinforcing agent has very strong permeability . its permeating length into c20 concrete can be 12 . 5mm and 4 . 5mm into c30 concrete 通过试验研究,以最佳掺量掺加助剂后,耐久性增强剂具有很强的渗透性,其在c20混凝土中的渗透深度可达12 . 5mm ,在c30混凝土中达4 . 5mm 。
Results indicated that the strength of the modified layer with the preoxidized pan fibers as the reinforcer was significantly higher than that of the modified layer with carbon fibers as the reinforcer 通过研究发现：用预氧丝作增强剂得到的改性膜的强度明显优于用炭纤维作增强剂得到的改性膜的强度。
At the same time , the combining intensity between the modified layer and the base with the preoxidized pan fibers as the reinforcer was stronger than that with the carbon fibers as the reinforcer 同时，用预氧丝作增强剂得到的改性膜与基体之间结合的强度也明显优于用炭纤维作增强剂得到的改性膜与基体之间结合的强度。
In order to improve the permeability and reinforcement of reinforcing agent , assistants and they dosages are studied when considering viscosity and economical efficiency of reinforcing agent 为了使表面增强剂获得更好的渗透性和更高的耐久性增强效果,考虑到耐久性增强剂粘度以及经济性,对助剂及其掺量进行了优化研究。
By optimising the combination of polymers , reinforcement and modification systems , and various additives , rhodia engineering plastics can offer you the most suitable products for your applications . technyl means quality 通过对聚合物，填充剂增强剂及其他添加剂的结合的优化和不断改良，罗地亚工程塑料将提供给您最满意的产品。
It is important for the protection of concrete structure . considering stability of reinforcing agent and basing on theoretical analysis , three methods including thickening , dispersing large grains and separating large grains are used 针对耐久性增强剂的稳定性问题,查阅了大量的资料,在理论分析的基础上拟定了三种方法:增稠法、分散大颗粒法和分离大颗粒法。
