In order to ensure that the surface of the pulled steel wire is clean and powder-free, a cleaning equipment device is used for cleaning treatment. An appropriate (usually 1%) metal surface treatment agent is added to tap water, and the surface of the steel wire is washed by a high-pressure submerged pump (1.1KW). At the same time, a cleaning ball is used to wipe the surface of the steel wire in the passage. In order to ensure that the surface of the steel wire is wrapped without water before entering the winding line, So, at the outlet of the steel wire, a high-pressure air blowing device is used to vigorously blow the steel wire surface 360 ° without gaps, ensuring that there is no water vapor in the steel wire during winding. This cleaning machine is divided into two layers: upper and lower, with a steel wire passage layer on top. The specification is 400X300X2000, which is made of stainless steel welded material. Inside, there are nine adjustable cone wiping devices, which tightly contact the steel wire and the cleaning ball for wiping; The lower layer is a water storage tank, with a specification of 800X700X1600, which is welded from 4mm stainless steel plate. There is a filtering area in the water tank, and the filtered water is pumped out from the anti-corrosion liquid pump on the water storage tank into the upper aisle water tank for flushing. The underwater pump will not block and has a longer lifespan. The lower water tank is equipped with a decontamination hole to remove debris and garbage. According to customer needs, in areas where the weather is too cold, an electric heating system or a steam heating system can be installed on the water tank, and the heating temperature can be designed to maintain a certain temperature for flushing and wiping with water.

Method for preparing cresol black medicine
The cresol black drug is formed by the action of cresol and phosphorus pentasulfide . The reaction formula is as follows:
The synthesis conditions and results are shown in the table. It can be seen from the table that when the reaction temperature is lower than 100 ° C, the reaction proceeds slowly or not at all (Test 1); when the reaction temperature is 100-110 ° C, a black drug with sufficient activity can be obtained (Test 6). However, the reaction proceeded slowly (190 minutes); at the reaction temperature of 120-140 ° C, the same results as above were obtained, and the reverse time was shortened, and the temperature was increased and the reaction rate was accelerated (tests 4, 7, 10). After the reaction is completed, heating at 170-180 ° C for two hours, the quality of the reaction product is greatly reduced (tests 9, 5, 11, 21, 24), it can be seen that the synthesis temperature is 120-140 ° C, the temperature is too high to produce dimethyl The phenolic dithiophosphoric acid will decompose.
When the pharmaceutical factory produces cresol black medicine, as long as the reaction material is heated to 130 ° C under stirring, the qualified product can be discharged, and the temperature of the product can be lowered to room temperature after a relatively long period of time in the storage. Therefore, it does not need to be heated for 2 hours.
