Study on Comparison among Papermaking Powder Properties

Abstract:

In this paper the comparison among some papermaking powder properties are studied. It shows that the properties of different powders are different because of different chemical composition and different preparation method and their particle size is different for different purpose such as filler and pigment. The particle size of powder for pigment powder is smaller than that for filler. The specific surface area of papermaking filler is lower than 20m²/g, the absorption value of DBP is about 45cm³/100g, the whiteness is up to 90%, and the particle size is about 3µm. The specific surface area of papermaking pigment is lower than 25m²/g, the absorption value of DBP is from 40 cm³/100g to100cm³/100g, the whiteness of clay is up to 50%, the whiteness of GCC and PCC is up to 90%, and the particle size is lower than 2µm. The specific surface area of silica is up to 100m²/g, the absorption value of DBP is up to 100cm³/100g, the whiteness is up to 97%, and the particle size is around 5µm.
