Problems solved by technology

[0003] At present, most of them are crushed by directly adding them to the crushing process, crushed into powder, and directly produced, changing their form from granules to powder state, but the existing technology can be crushed well when it is crushed. , but some granular AC foaming agents have impurities. When crushing, the impurities cannot be screened, resulting in impurity in the crushed AC foaming agent, and when crushing, it is easy to remove the Impurities are easily added to the AC blowing agent powder, which will also cause the powder to be impure

Embodiment 1

[0032] Using Moutan cortex as raw material, extracting paeonol therein, the method for extracting the active ingredient (paeonol) in Moutan cortex, comprises the following steps:

[0033] 1. A crushing method for AC foaming agent suitable for normal pressure foaming process, comprising the following steps:

[0034] S1. Use distilled water to soak the AC foaming agent particles. After soaking for 1 hour, use an ultrasonic cleaner to clean the AC foaming agent particles soaked in distilled water. Clean the impurities on the surface of the AC foaming agent particles, and then put them in the Store and reserve in a dry environment;

[0035] S2. The AC foaming agent particles cleaned in the above steps are first dried with a centrifugal dehydration device to remove the moisture on the outer surface of the AC foaming agent particles, and then the water-removed AC foaming agent particles use a dryer to dry the AC foaming agent particles thoroughly, and the dried AC foaming agent par...

[0047] The method of Example 1 provided in this example is roughly the same, and the main difference is that in step S2, it is pulverized into 120 mesh, and after dehydration in step S8, the temperature is respectively 40°C, 68.5°C, and 87.5°C, and the pressure is 17MPa, 25MPa. , 34.5MPa conditions for drying.

[0048] The frequency of the ultrasonic cleaning machine in step S1 is 35.5khz.

[0049] The rapid freezing device used in step S6 is cooled at a temperature drop of 18° C., and frozen for 2 hours.

[0050] The high-frequency high-voltage electromagnetic field condenser used in step S7 is subjected to polarity change, shock wave, and tearing at a rate of 180 million times / second, and is sent to a 350-mesh screen for screening.

Embodiment 3

[0052] The method of Example 1 provided in this example is roughly the same, and the main difference is that in step S2, it is pulverized into 150 mesh, and after dehydration in step S8, the temperature is respectively 50°C, 79°C, and 95°C, and the pressure is 19MPa, 30MPa. , 37MPa conditions for drying.

[0053] The frequency of the ultrasonic cleaning machine in step S1 is 40khz.

[0054] The rapid freezing device used in step S6 is cooled at a temperature drop of 18° C., and frozen for 3 hours.

[0055] The high-frequency high-voltage electromagnetic field condenser used in step S7 is subjected to polarity change, shock wave, and tearing at a rate of 200 million times / second, and is sent to a 400-mesh screen for screening.

Abstract

The invention relates to the technical field of crushing, in particular to an AC foaming agent crushing method suitable for a normal-pressure foaming process. According to the method, AC foaming agent particles before crushing are soaked in distilled water, the AC foaming agent particles soaked in the distilled water are cleaned by an acoustic cleaning machine, impurities on the outer surfaces of the AC foaming agent particles can be removed, and the AC foaming agent particles are dried and then added into an electronic screening machine for magnetic separation; the AC foaming agent particles which are uniform in size, free of damage and few in impurity are sorted and selected, the crushing effect is better when the AC foaming agent particles are automatically crushed, the impurities are reduced, rinsing is conducted after crushing, the impurities in a crushing machine are prevented from being brought into AC foaming agent coarse powder, the AC foaming agent coarse powder is rapidly cooled, and secondary crushing is conducted; and the frozen AC foaming agent coarse powder is easier to crush, and after being cooled, the AC foaming agent coarse powder is added into a condenser of a high-frequency high-voltage electromagnetic field to be shredded.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to an AC foaming agent crushing method suitable for normal pressure foaming process. Background technique [0002] Foaming agent is the substance that makes the target substance form pores, and it can be divided into three categories: chemical foaming agent, physical foaming agent and surfactant. Chemical blowing agents are those compounds that release gases such as carbon dioxide and nitrogen after thermal decomposition, and form pores in the polymer composition; physical blowing agents are foam pores that change the physical form of a certain substance , which is formed by the expansion of compressed gas, the volatilization of liquid or the dissolution of solid; the foaming agent has high surface activity, which can effectively reduce the surface tension of the liquid, and arrange the double electron layer on the surface of the liquid film to surround the air , forming bubbles, ...
