Properties of Secondary Fiber Recycling Straw


A change in the fiber surface passivation. The former refers to the fiber wall irreversible L-gap closed,[link widoczny dla zalogowanych], and even long after re-wetting 13 - asked the beating is still difficult to make fiber wall layers. The latter refers to the fiber surface of the depopulation. Eastwood made Taiwan the second fiber capacity loss Results from two aspects: changes in the state of fiber surface and fiber wet plasticity loss. Pre-drying conditions on the paper pulp fracture toughness and tensile strength results show that: dried fiber (second fiber) is not only flexibility and plasticity variation, showing tightness of the sheet down, and the hydrophilic nature of the fiber surface has been considerable damage, resulting in loss of fiber binding. 3 Back to the atlas of the sheet stack with stag head piece of the action of the bud of the amount of resistance to cracking La don kun breaking exhibitions that the number of attack c long KPa. / G of a white fiber binding KP straw decline in the second and pentosan content decreased closely related. Half-fiber tangled fine fibers by preventing the condensation of adjacent or co-crystal to reduce the horny. Back to the used | the process. Dissolution of low molecular weight polysaccharides and polysaccharide decomposition, on the one hand makes the swelling capacity of secondary fiber deterioration. Hinder flexibility and plasticity of fiber re-development; the other hand, makes the fiber surface hydrophobicity increased,[link widoczny dla zalogowanych], the free hydroxyl reduced. This leads to reduced bonded area between fibers, fiber bonding strength per unit bonded area on the reduction of the bond, which sheet tightness and tensile resistance,[link widoczny dla zalogowanych], strength properties such as breaking down. Straw pulp played the pentosan content and reduce water retention value greater degree. Sheet nature of tightness and strength corresponding to a larger downward trend. Studies have found that recycling can reduce the bonding strength of fiber more than 55%. Table 4 shows that make the reuse of reed pulp beating the tensile strength changes with the degree of tightness increases. Huan 'mushroom spawn back when the tensile stacked with saliva stag stag and the mutual relations Mu end by equation correlation of pulp greed feast on the most casual play r Wei Wei soup called policy Note: for the tensile strength, D, is back tightness tear with a straw in different trends. 14 have not decreased beating straw, wheat straw pulp played the opposite. As we all know,[link widoczny dla zalogowanych], beating the initial, the tear gradually increased with the degree of beating. However,[link widoczny dla zalogowanych], soon turning point, indicating that the excessive increase fiber binding, tear would have a \decreased, but the improvement is conducive to tearing. As an area of secondary fiber with reduced light scattering coefficient increased. mechanical pulp and chemical pulp in the recycling performance of different. played pulp and not beating the fibers also have different recycling properties . The straw, in addition to tear away, and played without beating pulp bleached pulp have similar reuse characteristics, the beating of the magma will increase trends. 3 Conclusion large number of studies have shown that secondary fiber back to the straw Performance with different secondary fiber pulp. beating performance of straw fiber back to have a great impact. view of the wealth of non-timber resources, and the current use of recycled fiber raw materials back to the trend of straw fiber Performance studies will be back for more. find straw decay period and the second law of fiber. to expand the application and use of secondary fiber value basis.
