    • PURPOSE: A film obtainable from polypropylene or other similar materials derived from polypropylene is provided, which optimizes the productive process of slabs made of marble agglomerates because this film solves one of the main problems that arise in this kind of production, namely, the removal of the protective material such as paper, rubber etc. from the slab when the baking phase is concluded and before the beginning of the subsequent phases in which the slab is finished off. CONSTITUTION: The detachable film is formed by a polypropylene layer(both copolymers and homopolymers) in several forms such as cast, extruded, coextruded, mono-biorientated forms or further forms, or other similar materials derived from polypropylene. The film can be directly used or formed on one side or both sides of paper supporting material by suitable bonding or extrusion systems. Unlike polyester, polypropylene accomplishes its antiadhesive function very well on the marble agglomerate, therefore polypropylene is used in the production of marble agglomerate.
    • 目的:提供聚丙烯或聚丙烯衍生的其他类似材料制成的薄膜,其优化了大理石聚集体制成的板坯的生产工艺,因为该薄膜解决了这种生产中出现的主要问题之一,即除去 保护材料如纸,橡胶等,当烧结阶段结束时,以及板坯终止的后续阶段开始之前。 构成:可分离膜由几种形式的聚丙烯层(共聚物和均聚物)形成,例如铸塑,挤出,共挤出,单成型或其它形式,或衍生自聚丙烯的其它类似材料。 膜可以通过适当的粘合或挤出系统直接使用或形成在纸支撑材料的一侧或两侧上。 与聚酯不同,聚丙烯在大理石附聚物上非常好地实现了其抗附着力,因此聚丙烯用于生产大理石附聚物。
