硅微粉是以天然白石英、熔炼石英为原料,经初选、破碎、研磨、提纯、脱水、分级等工艺精制而成,其质纯、色白、颗粒均衡。其主要特性如下:
1、硅微粉系中性无机填料,颗粒细微均衡,并可制成超细微粉;能与各类环氧树脂混合,浸润性好,吸附特性优良,无结团现象。
2、配方中加入硅微粉后可降低环氧树脂固化物反应的放热峰值温度,降低固化收缩率与线膨胀系数,减小内应力,有效地防止固化物开裂。
3、加入硅微粉能提高硬度,增加导热系数,降低产品成本。
4、硅微粉颗粒细,比表面积大,悬浮性能显著,无分层现象,有效地提高
Silica micropowder is refined from natural Bai Shiying and smelting Shi Ying through primary selection, crushing, grinding, purification, dehydration, classification and other processes. It has pure quality, white color and balanced particles. Its main characteristics are as follows:
1. Silica micropowder is a neutral inorganic filler with fine and balanced particles and can be made into ultrafine powder; It can be mixed with various epoxy resins, with good wettability, excellent adsorption characteristics and no agglomeration.
2. After adding silicon micropowder into the formula, the exothermic peak temperature, curing shrinkage and linear expansion coefficient of the cured epoxy resin can be reduced, and the internal stress can be reduced to effectively prevent the cured epoxy resin from cracking.
3. Adding silicon micropowder can improve hardness, increase thermal conductivity and reduce product cost.
4. Silica micropowder has fine particles, large specific surface area, remarkable suspension performance and no delamination, which can be effectively improved
