depainting

substitute fluidized bed for conventional depainting process

用流化床替代传统的脱漆工艺

a polyurethane depainting agent which uses dichloromethane as the main raw material was prepared and the optimum recipe for its secondary solvents and activators was found.

研制了以二氯甲烷为主原料的聚氨酯脱漆剂，并筛选出其中次溶剂、活化剂等的最佳配方。

the metal corrosion test and the tests of depainting the old paint films on the portion of and the whole body of the plane in the maintenance shop showed that the said depainting agent was highly effective and was worth spreading for use.

对该脱漆剂进行的金属腐蚀试验及在飞机维修厂进行的脱除旧漆膜现场小试及整机试验表明：该Ts&1聚氨酯脱漆剂脱漆效果良好，很有推广价值。

The paint shall be homogeneously applied without exposed undercoat and depainting, and minor scratch is not allowed;

涂漆均匀，无漏漆、脱漆现象，允许有轻微划痕；

the success of development of the depainting agent has opened a new way for the profound processing of dichloromethane in china.

该脱落剂的开发成功为我国二氯甲烷的深度加工开辟了新的途径。

the formula and preparation of the paint remover were described, physical and chemical properties and depainting results were tested.

介绍了脱漆剂的配方，并对其理化性能及脱漆效果进行了测试。

it indicates that fluidized bed has good applicability and suits the requirement of environment protection, can replace conventional depainting process and cleaning method.

结果表明，流化床适用性好、符合环保要求，将代替传统的脱漆工艺及清理方法。
