Extrusion Asia Edition 2-2022

25 Extrusion Asia Edition 2/2022 CERAMIN 地板以聚丙烯为基础材 料制成。具有无污染，100%可回收特 性，并使用回收材料生产。基于 CERA- MIN 地板覆盖物的坚固耐用，可为私人 住宅以及公共和工业建筑提供塑料地板 的所有优势。地板尺寸稳定、耐磨、防 水、触感温暖且耐紫外线。 传统的基于软PVC的塑料地板具有 可回收性差的缺点，并且由于其污染成 分如氯、稳定剂、邻苯二甲酸酯和其他 增塑剂而受到批评。这就是 CLASSEN 康麦森公司开发 CERAMIN 作为无 PVC 地板覆盖物载体板材料的原因。具体来 说，Ceramin 板由 60% 的天然矿物填 充材料、39% 的聚丙烯基聚合物和 1% 的 环 保 和 健 康 相 容 性 添 加 剂 组 成。CLASSEN 塑料地板中的载体板覆 盖有保护性底涂层以及底漆和装饰层， 具有柔软触感的表面处理，行走上面， 脚部倍感舒适。 在主要部件（即2至5mm厚的板 材）的生产过程中，板材必须绝对均匀平整、表面干净无波 纹，并符合极窄的强度公差范围，这当然是至关重要的。这对 于进一步加工以及以后用作地板覆盖物很重要。在 battenfeld- cincinnati 生产线中，具有高填料含量的 CERAMIN 板的无可 挑剔的质量标准主要归功于Multi-Touch压光辊。由于板和辊 之间的持续接触，该设备确保了校准和冷却的完美条件。 现场安装在 CLASSEN 公司的两条生产线配备了两台来 自德国纽伦堡的 Leistritz挤出设备有限公司的双螺杆挤出机， 它们与计量单元相连，可确保每小时高达 8 吨熔体的完美均 化。在下游，它们连接到一个自动平模头，熔体膜通过该模头 入 2.6 m 宽的Multi-Touch压光辊。接着，预校准在两个压光 辊中进行，然后板材通过多个辊进行重新校准。这样，板材在 相当长的一段时间内与辊面连续接触，生产出具有完美的尺寸 稳定性和出色的视觉属性。牵引机后是尺寸切割机。生产整线 由集成在客户的PDA 系统中的 BCtouch UX 控制系统操控。 在第二个处理步骤中，如上所述，用不同的膜层作为装饰层， 覆膜在板材上，从而在大范围、多样化的图案中选择装饰。 C ERAMIN is produced from polypropylene as base material. It is pollutant-free, 100 per cent recyclable and produced with recycled materials. The sturdy, durable floor coverings based on CERAMIN offer all the advantages of plastic flooring for private residences as well as for public and industrial buildings. The floors are dimensionally stable, abrasion- and water-proof, warm to the touch and resistant to UV light. Conventional plastic floors based on soft PVC have the disad- vantage of poor recyclability and are subject to criticism due to their pollutive ingredi-ents such as chlorine, stabilizers, phthala- tes and other plasticizers. This is why the CLASSEN Group has developed CERAMIN as a material for the car-rier boards of PVC- free floor coverings. In detail, CERAMIN boards consist to 60% of a natural mineral filler material, to 39% of polymers based on polypropylene, and to 1% of environmentally friendly and ➠ battenfeld-cincinnati Germany GmbH Bad Oeynhausen, Germany www.battenfeld-cincinnati.com ➠ CLASSEN www.classengroup.com health-compatible additives. The carrier boards in plastic floors from CLASSEN are covered with a protective undercoat as well as a primer and decorative layer with a soft-touch surface finish to make human feet feel comfortable. In the production of the main component, that is, the 2-to- 5-mm-thick board, it is of course vital that the board is absolu- tely even, has a clean, ripple-free surface and complies with ex- tremely narrow strength toleranc-es. This is important for further processing as well as for its later use as floor covering. In the battenfeld-cincinnati line, the impeccable quality standard of the CERAMIN board with high filler content is primarily due to the Multi-Touch roll stack. Due to continuous contact between the board and the rolls, this device ensures perfect conditions for calibration and cooling. The two lines now installed at CLASSEN are equipped with two twin screw extruders from Leistritz Extrusion GmbH, based in Nuremberg/Germany, which are connected to the dosing unit and ensure perfect homogenizing of up to 8 t of melt per hour. Downstream, these are connected to an auto-matic flat-sheet die, through which the melt film proceeds into the 2.6 m-wide Multi-Touch roll stack. Here, pre-calibration takes place in a two- roll stack, before the board passes through several more rolls for recalibration. In this way, the surface of the board is continu- ously in contact with the roll surfaces over a considerable period of time, with the result of perfect di-mensional stability and ex- cellent visual attributes. The haul-off is followed by a size cutter. The complete line is controlled by BCtouch UX, which is inte- grated in the customer’s PDA system. In a second processing step, the boards are laminated as described above with the va- rious layers of film and thus provided with a decoration chosen from a large, diversified range of patterns.
