纸板重点(国外英文资料) Topic: terminology, answer, discussion. (bold with black lines for the teachers thinking question) Chapter 1 Paper and paperboard, 1. Definitions of paper and Paperboard: paper and paperboard are a mesh structure consisting of macroscopic fibers and intricate intertwined structures. 2, paper structure: structure elements of the complex multiphase heterogeneous tissue: fiber, filler, adhesive and dye; structure of the paper is: the binding force of hydrogen bonding force (mainly), the main chemical valence, Fan Dehua force and surface force structure of the interleaving paper is not; continuous, is a kind of porous material: determines the absorption performance, air permeability, smoothness, absorbent paper, deformation when the change of water. (open hole, penetrating cavity, fiber internal voids) with the three-dimensional structure: vertical and horizontal, to Z; and has two sides: anisotropic forming, side and network side and blanket surface contact, contact. 3. Properties of paper and paperboard: The functional properties of the fiber paper to determine their own nature: the absorption and scattering of micro - structure; the hydrophilic with hydroxyl groups; hydrogen bonding ability and the strength; the softness; the combustible; the function of color; The fiber woven into the porous; II joined the functional material obtained: sizing, filling, etc.. 4, the performance of paper: general properties: appearance quality, quantity, thickness, tightness and dimensional stability; the mechanical properties: tensile strength, bursting strength, folding strength, elongation, compression strength, stiffness and tensile energy absorption; the permeability: air permeability, moisture permeability, oil penetration, water resistance, hydrophobicity and so on; the optical properties of whiteness, gloss, transparency, color (not); the surface properties: smoothness, friction coefficient, surface roughness, adhesion property and dusting performance; the printin
