高温水解炉操作简便，对环境无污染，是一种清洗精密喷丝板、过滤器、计量泵等部件经济适用的设备，尤其是清洗聚脂用“过滤芯”和BOPET或BOPA生产工艺中过滤器的清洗，较三甘醇清洗炉具有清洗效果好、成本低，特别是清洗小于15μm的微孔时更能显示出其清洗效果。
高温水解炉的工作原理：先把蒸汽加热到350℃左右，再将过热的蒸汽通入装有被清洗部件的清洗炉工作室，由于高温蒸汽的作用，大量聚合物被加热后，一方面温度升高聚合物流动性变好，大量的聚合物流入清洗炉下部的废料收集罐中，另一方面剩余的少量聚合物和高温蒸汽接触表面发生水解作用，产生越来越小的分子链，直到达到蒸汽状态，这些气体随蒸汽一起排出炉外，然后在一个合适的散热器中冷凝（冷凝物与冷却液混合物应作适当处理）。
水解过程所需的时间要根据被清洗聚合物的重量和被清洗部件的复杂程度以及蒸汽与聚合物表面接触程度有关，如清洗聚脂过滤芯，一般为6～8小时。
在充分水解后，后续工序是进行碱、水洗、高压水冲洗以及超声波清洗，以除去过滤芯中的钛白粉，然后经汽泡试验合格即可使用。
Hydrolysis washing oven can be operated easily and it doesn' t make any pollution. It is used to wash parts such as precisespinneret. filter. metering pump. etc and especially filter core for polyester and filter of BOPET or BOPA productionprocess. In comparison with peg washing oven. it is of good washing effect and low cost. When washjng micro porous
(15 u m) . hydrolysis washing oven is much better.
Working principle: First. heat steam to 350 C or so. and then pump the over-hot steam into working chamber of the washing oven. Because of steam of high temperature. lots of polymer is heated. After that. On the hand. fluidity of the polymer
becomes better and much polymer flows to the collection tank at the bottom of the washing oven; on the other hand. thelittle remaining polymer conducts hydrolytic action when touching high temperature steam and turns to produce smaller andsma I ler molecular chain until up to condition of steam. These gases is exhausted outside the oven with steam and condensedin a proper radiator (mixture of condensation product and cooling fluid should be treated properly).Time needed during hydrolysis process depends on weight of polymer ready to be washed. complex degree of parts to be washed and contact degree of polymer surface. For example. polyester filter core need to be washed for 6-8 hours.
After being completely hydrolyzed. the following procedure is alkali & water washing. high pressure water washing and ultrasonic washing to remove titanium dioxide in the filter core. At last, after passing the bubble test. it can be used.
