    摘要： A process for expanding or puffing fibrous or plastic materials such as paper, tobacco, cotton, asbestos, plastic films, etc., whereby the expandable material in sheet or filament form and a puffing agent are continuously advanced under pressure through a pressure zone defined between a pair of opposed surfaces which continuously separate at the zone outlet so that as the expandable material and puffing agent pass out of the pressure zone the agent expands and puffs the material. Heat is usually applied to the pressure zone to generate or increase the pressure therein. The puffing may be in the form of a liquid, such as water or fluorinated hydrocarbons, or a gas, such as steam. The puffing agent may be supplied separately to the pressure zone or concurrently with the expandable material.

    摘要翻译： 用于膨胀或膨化纤维或塑料材料如纸，烟草，棉花，石棉，塑料薄膜等的方法，由此将片状或长丝形式的可膨胀材料和膨化剂在压力下连续地通过压力区域 一对相对的表面，其在区域出口处连续分离，使得随着可膨胀材料和膨化剂从压力区域流出，试剂膨胀并且吹起该材料。 通常将热量施加到压力区以产生或增加其中的压力。 膨化可以是液体的形式，例如水或氟化烃，或气体，例如蒸汽。 膨化剂可以单独供应到压力区域或与可膨胀材料同时供应。
