热氧催化系统
(CATHOX)
Vitronics Soltec’s Catalytic Thermal Oxidizer (CATHOX)

热氧催化系统 (CATHOX) 一种能够使SMT回流炉腔保持干净,避免污染的先进系统。一个基于纳米材料的催化系统应用热化学反应分解从锡膏,电路板 和原元件中产生的有机物气体除挥发。这种纳米技术使得在200度温度条件下改变物质化学成分变成可能,这对回流焊工艺中去除挥发性化合物是非常有效的。在热氧化中,有机气体被转化成二氧化碳和水,以及微量的碳 。 该发明可以在回流炉的每个温区里安装催化单元,并最佳化温度控制。除了应用催化技术,用陶瓷球床达到均匀的细孔分布以及本身的耐热耐酸特性,也可促进催化剂活性 。

除了节约能源外,还能减少维护,这也意味大批量生产的产量和生产力的提高。 在批量生产产线上,机器零部件每两周要做维护。维护要停机才能做,因为要去除脏的,粘的助焊剂残留物。反之,有了催化剂和陶瓷球很长一段时间里就不需要做维护。 通常,一年做一次维护足够了。污染物通常由碳氢化合物组成,当热燃烧时,它们被化学氧化成二氧化碳和水。应用这个技术发明的好处是:

  • 保持加热区干净
  • 较少的能源使用
  • 大幅减少因换过滤或热交换器而引起的的停机时间
  • 没有浪费
  • 通过减少停机时间,生产可以达到高产出量。(SMTC@ACT)

The Catalytic Thermal Oxidizer (CATHOX) is an advanced system for keeping SMT reflow ovens clean and free of contamination. A nanomaterial-based catalyst system thermo-chemically decomposes organic materials outgassed from solder paste, bare boards and components. The nanotechnology makes it possible to change the chemical composition at temperatures around 200 ºC. It is very effective in removing volatile compounds from the process tunnel during reflow. In thermal oxidation, organic vapors are converted to carbon dioxide and water; little or no char is produced. This invention enables the installation of catalyst units in each individual zone of the oven, and temperature optimization. In addition to the catalyst, a bed of ceramic spheres promotes catalyst activity as a consequence of their unique pore size distributions and their stability to thermal, hydrothermal, and acidic conditions.

Apart from energy savings, the reduction in maintenance required is impressive. This means increased throughput (higher volumes) and productivity. In high volume lines, parts needs to be cleaned every two weeks, which involves downtime and dirty, sticky flux residues. Conversely, the catalyst and ceramic balls don’t require any maintenance for a much longer period. Typically, servicing only once a year is sufficient. The pollutants are generally hydrocarbon-based and when destroyed via thermal combustion, they are chemically oxidized to form CO2 and H2O. The main benefits of applying this invention include the following: Clean heating zones, Less energy required, Slash downtime by eliminating filter/heat exchanger cleaning, No waste, Higher throughput through less downtime or production interruptions.
