许多仍在使用的旧喷漆室的设计不能有效地处理目前使用的各种脱包装化学品。随着新涂料类型和更高固体含量的出现，这些新的去包装剂正在成为许多展台的规则，包括旧型号的展台。然而，与其废弃所有的旧展位，还不如简单而廉价地改造系统，使其安全高效地运行。本文介绍了几种改造旧展位的方案和方法，以实现高效的化学品利用和污泥去除。

MANY OLDER PAINT SPRAY BOOTHS WHICH ARE STILL IN SERVICE WERE NOT DESIGNED TO WORK EFFICIENTLY WITH THE TYPES OF DETACKIFYING CHEMICALS CURRENTLY IN USE. WITH THE ADVENT OF NEW PAINT TYPES AND HIGHER SOLIDS LEVELS, THESE NEW DETACKIFIERS ARE BECOMING THE RULE IN MANY BOOTHS, INCLUDING OLDER MODELS. RATHER THAN SCRAPPING ALL OLD BOOTHS, HOWEVER, IT IS POSSIBLE TO EASILY AND INEXPENSIVELY RETROFIT SYSTEMS TO OPERATE SAFELY AND EFFICIENTLY. THIS PAPER PRESENTS SEVERAL OPTIONS AND MEANS TO MODIFY OLDER BOOTHS FOR EFFICIENT CHEMICAL USE AND SLUDGE REMOVAL.
