The effect of borax on strength property of paper has been investigated in different ways. The use of borax either improved the physical properties or assisted in the reduction of refining energy to significant level.
The study of borax in the presence of precipitated and ground calcium carbonate was accomplished by using white water recycling. In the absence of retention aids, recycling of white was a necessary condition for the retention of ash content. As the ash content increased the strength property decreased. But the presence of borax slowed down the detrimental effect of fillers.
Sizing development progressively improved especially at high dosage of AKD addition and for all levels of borax addition. Noticeable change had not been observed in terms of strength properties. The inclusion of filler in the borax and AKD system showed detrimental effect on strength development. Neither borax nor AKD were able to counteract the negative role of the filler. The result of size reversion was inconclusive.
Borax in the surface application was insignificant to bring property changes.
