Moreover, most of the work needs to be pre-treated before surface treatment, for example, cleaning, decontamination and degreasing, and wax removal for some specific workpieces.

 [0003] Conventional wax removal uses organic solvents, some organic solvents such as triphenyl solvents have greater toxicity, do not meet environmental protection requirements, or use strong acid corrosion, which poses a safety hazard and corrodes the workpiece. Some wax powders have a certain wax removal effect, but the wax removal rate is slow, the removal is not thorough enough, the wax removal cycle is long, and there are defects such as spots.

 technical problem

 [0004] In view of the above, a solution for removing wax and its application problem in which the wax is quickly and thoroughly, safely and environmentally friendly, and has a long-lasting effect is provided.

 Technical solution

 [0005] A wax removing powder comprising 5-20 parts by weight of triethanolamine oleic acid soap, 35-80 parts by weight of sodium tripolyphosphate, 5-10 parts by weight of sodium metasilicate pentahydrate, 5-10 parts by weight of ethylene glycol monobutyl ether.

[0006] Moreover, the above-mentioned wax removing powder is used for the surface wax removal, descaling, and polishing treatment of the metal workpiece.

 Advantageous effects of the invention

 Beneficial effect

[0007] The above-mentioned wax removing powder adopts the combination of the above-mentioned formula components, and has the characteristics of quick and complete wax removal, strong wettability and permeation ability, low compounding concentration, long-lasting effect, excellent anti-corrosion effect, etc., and acts on the surface of the workpiece. The working surface is characterized by brightness, no spotting and good washing performance. Embodiments of the invention

 The invention will be described in detail below with reference to specific embodiments.

 [0009] A wax removing powder, the wax removing powder comprising 5-20 parts by weight of triethanolamine oleic acid soap, 35-80 parts by weight of sodium tripolyphosphate, 5-10 parts by weight of sodium metasilicate pentahydrate, 5-10 parts by weight of ethylene glycol monobutyl ether.

 [0010] Specifically, the triethanolamine oleate soap is preferably 5-15 parts by weight. The proportion by weight of sodium tripolyphosphate is preferably from 40 to 70. The weight fraction of sodium metasilicate pentahydrate is preferably 6-9. The weight fraction of ethylene glycol monobutyl ether is preferably 6-9.

 [0011] The above wax removing powder is mainly used for wax removal, descaling and polishing treatment of metal or plastic workpiece surfaces. For example, the application method includes the following steps:

[0012] Solution preparation: Add tap water in the ultrasonic tank, heat 35-40 ° C, slowly add 2 under stirring

0-50g/l of wax removal powder, because the wax removal powder is difficult to dissolve, it needs to be fully stirred and then heated to 60-90 °C to be used.

 [0013]
