开口剂 超细二氧化硅 白炭黑 屹诺

二氧化硅 Anti-caking agent(food grade）◆产品简介抗结剂又称干燥剂 吹干粉，产品用于防止颗粒或粉状类食品聚集结块，保持其松散或自由流动的物质。主要应用于香精、香料、饲料、药品等行业。Series silicon dioxide additive are main used as water reducing,stabilization of food、medicine、animal food and carrier,clarify assistance and the attach water reducing of essence and spicery.The form of the product is white powder.Because of the sub-micro size and large BET of silicon dioxide,it can act as interval material between the granules of powder,at the same time,it also can improve the free flow of powder.Its water reducing feature can promote sorption and to prevent caking.Also can be used in medicine industry.
