[Outline]
The project mainly adopts AKD neutral/alkaline papermaking technology and poly-nano-colloidal silicon microparticles retention and filter aid cleaning technology, which can effectively reduce the solid content of paper white water and improve the whiteness and surface strength of paper. Whiteness: 92%, quantification: 80g/m2, surface absorption weight less than 30g/m2, print surface strength is not less than 2.0m/s, ash content is 8-20%.
