The invention discloses a detergent production technology for improving washing quality. The technology comprises the steps of 1) adding modified acrylic resin, an emulsifying agent and a rust removerto a reaction kettle; and stirring; 2) adding tetrachloroethylene and a nonionic surfactant to another reaction kettle; stirring; then adding sodium carbonate, a degreasant and ethanol amine; and continuously stirring; 3) mixing solutions obtained in step 1) and step 2); 4) sequentially adding sulfuric acid, hydrochloric acid, nitric acid and phosphoric acid to a glass vessel; stirring; then dropwise adding hydrofluoric acid and ammonium bifluoride; stirring; adding potassium thiocyanate; and stirring; and 5) adding the solution obtained in step 3) to the solution obtained in step 4); addinga penetrating agent; and stirring. The industrial detergent is nonflammable and is capable of rapidly cleaning oil dirt on the surface of a metal workpiece; and the industrial detergent can be degraded in water. Therefore, the washing speed can be improved, and the washing steps are simplified; the operation is simple and convenient; in addition, the detergent is safe, environmentally friendly, and energy saving; the industrial production is conveniently carried out; and the applicable scope is wide.
