一共三段話(huà)，相同的部分希望可以使用不同的表述方法 1.環(huán)氧樹(shù)脂含量越高，環(huán)氧基團(tuán)與氨基之間以及環(huán)氧基團(tuán)與環(huán)氧基團(tuán)之間的反應(yīng)更加充分，最終表現(xiàn)為模具材料的強(qiáng)度更大。二氧化硅的含量高時(shí)，硅烷偶聯(lián)劑對(duì)其表面的修飾不夠徹底，二氧化硅無(wú)法很好的融入反應(yīng)體系中，最終表現(xiàn)為模具材料強(qiáng)度的降低。 2.固化劑含量越高，氨基與環(huán)氧基團(tuán)之間的反應(yīng)更加充分，最終表現(xiàn)為模具材料的強(qiáng)度更大。二氧化硅的含量高時(shí)，硅烷偶聯(lián)劑對(duì)其表面的修飾不夠徹底，二氧化硅無(wú)法很好的融入體系反應(yīng)中，最終表現(xiàn)為模具材料強(qiáng)度的降低。 3.固化劑含量越高，氨基與環(huán)氧基團(tuán)之間的反應(yīng)更加充分，最終表現(xiàn)為模具材料強(qiáng)度的提高。表面活性劑用量過(guò)大時(shí)，在攪拌過(guò)程中會(huì)產(chǎn)生更多的氣泡，存在于模具材料中，致使模具材料的強(qiáng)度有一定程度的降低。 [ 來(lái)自科研家族 快樂(lè)家族 ] |

1. The higher the content of epoxy resin, the more complete for reactions between epoxy groups and amino groups and between epoxy groups, which consequently performed as higher strength of the die material. When there is high content of SiO2, the surface modification by silane coupling agent is incomplete. As a result, SiO2 could not be well mixed in the reaction system and finally led to reduced strength of the die material. 2. Higher content of curing agent would enable reactions between amino groups and epoxy groups more complete, which was consequently indicated as higher strength of the die material. With high SiO2 content, the surface will not be fully modified by silane coupling agent. Thus SiO2 could not be well integrated in the reaction system and finally cause a decrease in the strength of the die material. 3.The higher the curing content, the more complete will it be for reactions between the amino groups and epoxy groups. Consequently it was represented as an increase in the strength of the die material. The higher dose of surfactant, the more bulbs produced during the stirring process in the die material. As a result, the strength of die material will to some extent be reduced. |
