Problems solved by technology

Although the vacuum defoaming treatment of shower gel by the above-mentioned technology will not cause secondary pollution, the defoaming effect on high-viscosity washing products such as shower gel is not ideal
[0005] From the above analysis, it can be seen that none of the existing defoaming technologies can achieve rapid and efficient defoaming of industrially produced high-viscosity washing products, which affects the production efficiency and cost of enterprises

Embodiment 1

[0037] The production method of the cleaning product provided by the present embodiment comprises the following steps:

[0038] S1: Weigh 100kg of ammonium lauryl sulfate, 50kg of cocamidopropyl betaine, 50kg of sodium lauroyl sarcosinate, 50kg of sodium laureth sulfate, and 10kg of sodium lauryl sulfate, and add them to 750kg In the pure water preparation tank, turn on the stirrer and control its stirring speed to 35Hz; start the heater to heat the feed liquid to 75°C;

[0039] S2: Insulate and stir for 25 minutes, and repeatedly vacuumize during this process. Each time when the vacuum degree reaches -65kPa, keep the pressure for 5 minutes and then inject air to remove the vacuum, so that the pressure in the preparation tank returns to atmospheric pressure, and the vacuum degree from atmospheric pressure reaches - The time of 65kPa is 40s, the time of air injection is 15s, and the number of times of vacuuming is 4 times;

[0040] S3: Cool the temperature of the feed liquid t...

Embodiment 2

[0045] The production method of the cleaning product provided by the present embodiment comprises the following steps:

[0046] S1: Weigh 200kg of ammonium lauryl sulfate, 150kg of cocamidopropyl betaine, 150kg of sodium lauroyl sarcosinate, 150kg of sodium laureth sulfate, and 50kg of sodium lauryl sulfate, and add them to 300kg In the pure water preparation tank, turn on the stirrer and control its stirring speed to 25Hz; start the heater to heat the feed liquid to 72°C;

[0047] S2: Insulate and stir for 30 minutes, and repeatedly vacuumize during this process. Each time when the vacuum degree reaches -70kPa, keep the pressure for 4 minutes and then inject air to remove the vacuum, so that the pressure in the preparation tank returns to atmospheric pressure, and the vacuum degree from atmospheric pressure reaches - The time of 70kPa is 35s, the time of air injection is 20s, and the number of times of vacuuming is 6 times;

Abstract

The invention provides a defoaming method of a washing product. The method comprises the following steps: mixing raw materials of the washing product; increasing the temperature to be 72-76 DEG C with continuous stirring; maintaining the temperature and stirring, wherein vacuumizing is carried out in at least two times during stirring, and the vacuum degree in each vacuumizing reaches -60 to -80kPa; maintaining the pressure for 3-7min; then recovering to the atmosphere pressure; decreasing the temperature to be 45-49 DEG C with continuous stirring; repeating step 2. According to the method, a mode of alternatively changing the vacuum degree is adopted, so that the purposes of effectively removing foam and quickly decreasing foam quantity can be achieved, and as a result, the foam of the washing product can be quickly removed.

Description

technical field [0001] The invention belongs to the field of daily chemical products, and in particular relates to a quick defoaming method for washing products. Background technique [0002] During the preparation process of washing products, the feed liquid will inevitably come into contact with the air, and the process of feeding, stirring and mixing of the materials also increases the chance of contact between the feed liquid and the air, so under the action of the surfactant, it will Produces copious lather. In the actual production process, the packaging of washing products requires that there should not be a lot of foam in the product, but since the formula of washing products does not contain raw materials with defoaming effect, it will take a long time to wait for the foam to burst naturally, thus As a result, the packaging cannot be immediately divided or the packaging efficiency is low after the processing is completed, which affects the production capacity of th...
