The mechanical properties of gross rubber before and after aging were detected when mixed hexaphenyl cyclotrisilazane with methyl vinyl silicone rubber in different ratio. 将六苯基环三硅氮烷与甲基乙烯基硅橡胶按照不同配比共混得到混炼胶,测定老化前后混炼胶的力学性能。
So constructing the natural rubber and sugarcane production function and analyzing the factors that affecting the outputs of the two products have far-reaching significance for raising the gross output of natural rubber and sugarcane. 因而构建天然橡胶和甘蔗生产函数模型,对影响这两种作物产量和产值水平的因素进行定量分析,对提高海南天然橡胶和甘蔗产量和产值水平具有积极意义。
The gross rubber has a high plasticity and fluidity and gumminess of composition is increased. 其具有较高的塑性及流动性并使胶料粘性增加。
The DNS-2 nano-silica has a similar reinforcing effect to nano-silica compared with A-200, but the gross rubber of the DNS-2 system was softer and has better processability than that of A-200. DNS-2纳米二氧化硅增强性能与气相法二氧化硅的相当,但前者混炼胶黏度较小,有较好的加工性。
