    • Polypropylene is one of the most commonly used plastics in furniture and various structures (such as for example plastic warehouses) due to its cheap price, friendliness to the environment (in terms of degrading in a reasonable time when thrown away as waste), and good strength per weight factor. However, one of its biggest disadvantages is that like Teflon it is very inert, and therefore it is very hard to paint it after production or to connect other materials to it for example through chemical means, ultrasound, or with heat. Although it is possible to add various patterns or textures, such as for example wood-like patterns to the cast, and although is possible to add for example more colors without mixing them or with only partial mixing in order to get more than one color, such a mixing cannot be precisely controlled and cannot be made to fit with the texture, whereas for example wood texture would require proper color changes in correlation with the texture. The present invention solves the above problems preferably by manufacturing the Polypropylene (for example by appropriate casting or extrusion) with a texture that can easily connect mechanically to other materials preferably by small protrusions such as for example T shaped protrusions and/or other protrusions that preferably become wider at their ends and/or various grooves that preferably become wider in their deeper parts. This is preferably done in combination with various corrugated structures. The same or similar methods can be used also for example for connecting various materials to structures made out of Teflon or of other chemically inert materials which are hard to connect to.
    • 由于其价格便宜,对环境的友好(在合理的时间内作为废弃物被贬低),因此聚丙烯是家具和各种结构(如塑料仓库)中最常用的塑料之一。 强度每重量因子。 然而,其最大的缺点之一是像特氟隆这样非常惰性,因此在生产后很难涂漆,或者通过化学方式,超声波或热量将其他材料连接到其上。 虽然可以向铸件添加诸如木状图案的各种图案或纹理,并且虽然可以添加例如更多的颜色而不混合它们,或者仅仅是部分混合以获得多于一种的颜色, 这样的混合不能被精确地控制,并且不能使其与纹理相适应,而例如木材纹理将需要与纹理相关的合适的颜色变化。 本发明优选地通过制造聚丙烯(例如通过适当的铸造或挤出)来解决上述问题,其结构可以容易地机械地连接到其它材料,优选地通过小的突起例如T形突起和/或其它突出物 在它们的端部和/或其较深部分中优选变得更宽的各种凹槽变宽。 这优选与各种波纹结构组合进行。 也可以使用相同或相似的方法,例如将各种材料连接到由特氟隆或其它难以连接的化学惰性材料制成的结构上。
