Forenede silica røg
Forenede silica røg (Microsilica)
Forenede silica røg, also known as raw silica fume or primary silica fume, it is chemically similar to densified silica fume, but a different density.This type of silica fume is incredibly light, has a density of 250-350 kg/m3, is very active, and requires a large storage space.
Undensified silica fume is more convenient to use, because of the characteristics of small particles, easy to disperse, basically do not need to increase the concrete mixing time. It has the characteristics of increasing the compressive and flexural strength of concrete, water penetration resistance, good filling effect and good adaptability to water reducing agents. The color of as-built silica fume will be lighter than that of densified silica fume, so it will not deepen the color of concrete.
The low bulk density of Undensified silica fume leads to higher transport costs,manufacturers need to invest more packaging costs, in addition, the Undensified silica fume is more active, easy to drift caused by the phenomenon of fly ash on site feeding, resulting in secondary pollution.
Undensified Silica Fume Advantages
Greater Impermeability
Barring the ingress of moisture, chemicals and other contaminantsHigh Early Strengths
Assuring increased efficiency and greater cost effectiveness in production of prestressed and precast concreteHigh Compressive Strengths
Proportionate to amount of silica fume and the water-to-cementitious ratioGreater Resistance
Substantially greater resistance to corrosion, abrasion and erosion, chemical attack and freeze/thaw damageUndensified Silica Fume Applications
- Ildfaste materialer. Silica dampe er almindeligt anvendt i støbning, sintrede, og smeltede ildfaste materialer. F.eks, det kan bruges i høj ydeevne, høj kvalitet, og lav-cement ildfaste støbegods og præfabrikerede dele, luftgennemtrængelige mursten, storstilede jerngrave og øser, og mere.
- Mørtel og beton. Silica-røg kan også bruges til havnekajer, højhuse, jernbanebroer, reservoirdæmninger, betonbelægning, og mere.
- Beskyttende belægninger. Nano-silica sol tjener som et aktivt materiale til brandbeskyttelse, miljøbeskyttelse, og antikorrosiv belægning.
- Væg og dekorative materialer. Silica-røg kan også bruges til termisk isoleringsmørtel, polymermørtel, og som grænseflademiddel til vægisolering.
- Kitt. Microsilica kan bruges i spartelpulver til udvendig og indvendig vægisolering.
- Fyldning og forstærkning. Det bruges også som fyld- og forstærkningsmaterialer i harpiks, gummi, maling, umættet polyester, og mere.
- Tilsætningsstoffer. Endelig, silica dampe er almindeligt anvendt som et tilsætningsstof i andre aktive områder.
