At waste ph below 4, the oxidizing power of the chromic acid begins to attach the resin . 当废水pH值低于4时，铬酸的氧化力开始吸附在树脂上。
The successful application of the size and of resin depends on the successful elimination of air . 施加胶料和施加树脂的成功取决于充分排除空气。
When the resin is exhausted, exchange capacity can be regenerated with weak alkali-ammonia solution . 当交换树脂饱和后，可用弱碱-氨溶液进行再生。
Table 3 shows the properties of four different gumstock systems employing different resins and terpolymers . 表3指出了应用不同树脂和三聚物的四种不同胶的性质。
When the fibres are in contact, the resin will form a tricorne-a triangle with curved sides . 在纤维互相接触时，树脂就形成一个曲边三角体--一个带有曲边的三角形。
The box girders were to be precast units, bonded together in place at the joints with an epoxy resin . 箱梁采用预制构件，在现场连接处涂以环氧树脂，以粘结成为整体。
Only the thermosetting resins provide a strong cohesive forces; this is due to molecular cross linkages . 只有热固性树脂具有巨大的凝聚力，这是由于分子交错链所造成的。
The coupling agent presumably improves the bond between the glass surface and the resin matrix in a laminate . 偶联剂的作用是设想能改善层压板中纤维表面与树脂基体的粘结。
Sodium chloride and hydrochloric acid are often used to regenerate spent ion exchange resins used in water purification . 氯化钠和盐酸常用来再生水净化中用的废的离子交换树脂。
However, apart from the technological difficulties of preparation, casting resins affords a further wide field of application . 然而，除了制备工艺的困难外，模浇树脂有更广泛的应用范围。
