94% دخان السيليكا غير المكثف

94% Undensified Silica Fume is a micro-silica fume with 94% محتوى SiO2, and the Bulk density is 250-400kg/m³.

Densified Silica Fume is to improve the density of micro-silica fume in order to reduce the transportation cost and improve the use performance. Before Densified, its density is about 150 إلى 200 كجم / م³, after densified, يمكن أن تصل 700 كجم / م³, مما يقلل بشكل كبير من الحجم ويحسن حجم الجسيمات في نفس الوقت. The densified process used nowadays is to use the airflow formed by compressed air to prompt the micro-silica fume in the container to collide with each other and rely on its own aggregation and adsorption to exclude the surface gas, thus forming multiple small particles with increased capacity to achieve the purpose of densified.
