Effect of different size ratio and filling method on the characteristics of calcium silicate-filled paper

open access: yesBioResources, 2022
Process conditions were investigated relative to the use of the fly ash pre-desilication-alkali lime sintering method to extract calcium silicate, which is a by-product of alumina co-production technology, for use as paper filler. The ratio of different fiber raw materials, filler filling ratio, and filling method were studied, and papermaking ...
