    摘要： The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate. More specifically, this invention is directed to a method whereby a low emissivity radiant barrier material is joined in situ to a mat of lignocellulosic particles using a second adhesive material, during the consolidation of the lignocellulosic particles and a first adhesive bonding material to form an underlying substrate, an integral laminated radiant barrier covered lignocellulosic product being produced.

    摘要翻译： 本发明的方法在底层木质纤维素基材的初级制造操作中将低辐射辐射阻挡材料粘附到下面的木质纤维素基材上。 因此，辐射阻挡层覆盖的基底是通过将辐射屏障覆盖物与其固化期间的第一粘合剂粘合材料整体地接合到木质纤维素材料垫而形成的，以形成下面的基底。 整体连接操作可以例如通过将辐射屏障覆盖物粘合到产品层压机中的木质纤维垫上来实现。 这通常使用用于将辐射阻挡材料粘附到木质纤维素垫的第二粘合剂粘合材料和用于固结木质纤维素垫以形成木质纤维素基材的第一粘合剂粘合材料来实现。 更具体地说，本发明涉及一种方法，其中低辐射辐射阻挡材料在木质纤维素颗粒固化期间使用第二粘合剂材料原位连接到木质纤维素颗粒垫上，第一粘合剂粘合材料形成底层 底物，正在生产的整体层压辐射屏障覆盖的木质纤维素产品。

    摘要： Apparatus for making an acoustical tile having a pattern of raised portions and portions in relief on the tile surface is provided by a hollow embossing roll containing the pattern in reverse and interstices communicating from the surface of the roll into the hollow interior of the roll. In operation the roll contacts the formable, acoustical tile fiber composition pulp with sufficient force as to disspell the pulp, vent air that may be between the roll and the pulp surface through the roll, and produce a reversed pattern of the roll upon the pulp surface, then releasing the pulp from the surface of the roll by rotation of the roll.

    摘要： Polymer, co-polymer and/or elastomer containing paper is manufactured for a wide variety of end uses. The paper is remarkably homogeneous and retains its porosity even when it contains large quantities of polymer, co-polymer or elastomer. The latex and the fibrous slurry are mixed at the wet end in conjunction with a polyelectrolyte bridging agent, the bridging agent having a cationic charge and the latex and fibrous material having an anionic charge. In this way, the latex particles in their substantially original size become linked with the fibrous material by means of the intermediate bridging agent and without the latex undergoing any substantially coagulation or precipitation.
