高溫水解爐操作簡便，對環境無汙染，是一種清洗精密噴絲闆、過濾器、計量泵等部件經濟適用的設備，尤其是清洗聚脂用“過濾芯”和BOPET或BOPA生産工藝中過濾器的清洗，較三甘醇清洗爐具有清洗效果好、成本低，特別是清洗小於15μm的微孔時更能顯示出其清洗效果。
高溫水解爐的工作原理：先把蒸汽加熱到350℃左右，再將過熱的蒸汽通入裝有被清洗部件的清洗爐工作室，由於高溫蒸汽的作用，大量聚合物被加熱後，一方麵溫度升高聚合物流動性變好，大量的聚合物流入清洗爐下部的廢料收集罐中，另一方麵剩餘的少量聚合物和高溫蒸汽接觸錶麵發生水解作用，産生越來越小的分子鏈，直到達到蒸汽狀態，這些氣體隨蒸汽一起排出爐外，然後在一個合適的散熱器中冷凝（冷凝物與冷卻液混合物應作適當處理）。
水解過程所需的時間要根據被清洗聚合物的重量和被清洗部件的複雜程度以及蒸汽與聚合物錶麵接觸程度有關，如清洗聚脂過濾芯，一般為6～8小時。
在充分水解後，後續工序是進行堿、水洗、高壓水沖洗以及超聲波清洗，以除去過濾芯中的鈦白粉，然後經汽泡試驗合格即可使用。
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.
