Table 1: phosphorus-free alkaline water-based spray cleaning antirust agent and traditional cleaning solution performance pair
The invention uses water to dilute the stock solution, is widely suitable for spray cleaning and rust prevention of manufactured parts such as steel, cast iron and the like, and the specific concentration of the prepared solution needs to be verified and determined according to the requirements of customers.
When the invention is used:
injecting a proper amount of water into the liquid storage tank, starting a tank liquid circulating system of the cleaning equipment, gradually adding the device into the liquid storage tank, preliminarily judging whether the device is completely diluted or not according to the tank liquid circulating capacity of the cleaning equipment, and detecting whether the concentration of the diluent reaches the standard or not by using a handheld refractometer;
if the manufacturing part is sprayed and cleaned by the invention with a certain concentration (3-8%), additional cleaning and rust prevention processes are not needed in the process;
if the invention with higher concentration (10-20%) is used for drying the manufactured part after spraying and cleaning, the general middle-term rust prevention requirement can be met;
if the manufacturing piece is dried after being sprayed and cleaned by the invention, the manufacturing piece can be directly dipped and coated with the anti-rust oil without being cleaned when the manufacturing piece needs to be anti-rust for a medium or long time;
the refraction and pH value detection of the working solution are carried out every day to ensure the service performance of the working solution.
On the basis that the design of cleaning equipment reaches the standard, the oil stain floating on the surface of the working solution needs to be separated from the system regularly, so that the service life of the working solution can be prolonged, and the cleanliness of cleaned manufactured parts is guaranteed.
The relevant performance indexes of the invention are shown in table 2:
table 2: the phosphorus-free alkaline water-based spray cleaning antirust agent has relevant performance indexes.
