preparation example 1-8
[0054] Preparation Examples 1-8 provide a cryogen particles and a preparation method thereof. Table 1 below shows the content of the raw materials used in the cryogen particles in Preparation Examples 1-8.
[0055] Table 1 Content of raw materials used in refrigerant particles (kg)
[0056]
[0057]
[0058] The preparation method of the cryogen particles of Preparation Examples 1-8 is as follows:
[0059] Add sucrose, sodium chloride, potassium chloride, calcium chloride, and carbon powder into warm water at 50°C to melt in the above proportions, stir at a speed of 100r / min for 20min, then heat and boil the mixture, boil the water and analyze the solid. Continue heating until the solids are completely melted, yielding a syrup. Then transfer the syrup to the preheated closed kettle, the temperature of the closed kettle is controlled to be higher than the temperature before the transfer of the syrup, and then use an air pump to pass ammonia gas into the closed kettle at ...
Embodiment 1
[0062] Embodiment 1 of the present application discloses a method for processing a steel belt for a coil spring of an automobile seat belt, comprising the following steps:
[0063] S1: Pickling, first peel the carbon steel to loosen the oxide scale on the surface of the steel strip, and it is easier to remove the rust and wear on the surface of the steel strip; then put the steel strip into the acid tank, react with hydrochloric acid, and the concentration of hydrochloric acid is 15wt%, the temperature of the acid tank is 30 ℃, and the pickling time is 10min; after the pickling is completed, the hydrochloric acid residue on the surface of the steel strip is washed with water; enter the brushing machine, and brush off the residue after the pickling reaction on the surface of the steel strip After entering the neutralization tank, the pH value of the neutralization tank is between 6-8, which can protect the surface of the steel strip from rusting; after the surface passivation tr...
Embodiment 2
[0091] The difference between Example 2 and Example 1 is that the cryogen particles prepared in Preparation Example 2 are used as the cryogen particles.
