Surface Permeability of High Porosity Plug Wrap Paper and Its Effect on Adhesive Property of Central Line Adhesive
In order to study the causes of adverse problems with poor adhesion performance between high porosity plug wrap paper and filter rod,the structure and characteristics of high porosity plug wrap paper were analyzed,the permeability on the surface of high porosity plug wrap paper was studied by dynamic contact angle method,and the effect of permeability on adhesive property of central line adhesive was al-so discussed.The results showed that the high porosity plug wrap paper had a low density,no obvious fiber splitting,a large number of pores between the fibers,and strong permeability of water on its surface.The permeability of central line adhesive on the surface of high po-rosity plug wrap paper was very different from that of water.The viscosity was the main factor affecting the permeability of central line adhe-sive.The viscosity was lower,the penetration was faster.The permeability of the central line adhesive on the surface of the high porosity plug wrap paper was closely related to the bonding effect.The viscosity of the central line adhesive was higher,the high porosity plug wrap paper had the better the bonding effect.However,different central line adhesives had different optimal opening time,beyond which the problem of poor bonding would occur.
