[0001] The present invention relates to the technical field of strong oil powder heavy oil cold water foaming agents, and in particular to a strong oil powder heavy oil cold water foaming agent applicable to various scenarios. Background Art

[0002] The existing foaming agents on the market mainly rely on Junzheng caustic soda, caustic soda, and strong sodium oxide, which can only be used by heating with hot water or boiling water, that is, high temperature (above 80°C) is required to activate the cleaning power. Due to the high corrosiveness, various equipment parts will be corroded, discolored, and damaged.

[0003] In various occasions on the market, special utensils and tools are also required to heat water for use. When in use, not only will there be a particularly pungent smell that causes great harm to the human respiratory tract, but also a large amount of time will be wasted in use.

[0004] Therefore, in view of the problems that the above-mentioned foaming agents need to rely on high temperature for use, have high energy consumption, limited scenarios, strong corrosiveness that is easy to damage equipment, and will also produce irritating odors that endanger human health when in use, a strong oil powder heavy oil cold water foaming agent applicable to various scenarios can be designed. Summary of the Invention

[0005] In order to overcome the problems that traditional foaming agents need to rely on high temperature for use, have high energy consumption, limited scenarios, strong corrosiveness that is easy to damage equipment, and will also produce irritating odors that endanger human health when in use.

[0013] S11: Remove lumps and impurities of food-grade granular sodium hydroxide through a vibrating sieve with a pore diameter of 200 μm to ensure uniform particles, store in a dry environment with a humidity ≤ 30%, and avoid moisture absorption and caking;

[0014] S12: Premix sodium metasilicate pentahydrate and CAB-35 coconut oil amide propyl betaine surfactant in a mass ratio of 1:1 to form a premixed solution, where the premixing temperature is controlled at 25 ± 2 °C to avoid surfactant stratification;

[0015] S13: When pretreating methyl tert-butyl ether solvent, introduce nitrogen gas into a closed container for 5 minutes to remove oxygen and prevent oxidation;

[0016] S14: Dilute sunset yellow pigment and lemon essence with 0.5% of the total mass of methyl tert-butyl ether to make a premixed solution;

[0017] S2: Mixing and stirring

[0018] S21: Sequentially pour the sodium hydroxide particles treated in S11, the premixed solution of S12, the methyl tert-butyl ether solvent treated in S13, the pigment and essence premixed solution of S14, and trace additives into a double-helix conical mixer for mixing treatment;

[0019] S22: After mixing, turn on a vacuum pump with a vacuum degree of -0.08 MPa to defoam for 5 minutes to avoid particle pores;

[0020] S3: Molding and drying

[0021] S31: Granulation treatment

[0022] Use a rotary granulator with a 1.5 mm sieve plate, control the feeding speed at 20 kg / min, and the rotation speed at 150 rpm to obtain preliminary particles;

[0023] S32: Drying and solidification

[0024] Use a belt dryer to solidify the above-mentioned particles, where the temperature of the feeding section is 45 °C, the time is between 10 - 12 minutes to remove the surface solvent; the temperature of the solidification section is 60 °C, the time is between 19 - 21 minutes to complete the crystal form transformation; the temperature of the cooling section is 30 °C, the time is between 3 - 5 minutes to prevent caking;

[0025] S33: Screening treatment

[0026] First, a primary sieve with an aperture of 800 μm is used to remove oversized particles; then, a secondary sieve with an aperture of 100 μm is used, and the material passing through the sieve is returned to the granulator.

[0027] S4: Packaging

[0028] An aluminum foil composite bag with a barrier property ≥ 95% is used, lined with a PE film, and each bag has a net weight of 25 kg.

[0029] Preferably, in the dry mixing and stirring stage of S21, the rotation speed of the double - screw conical mixer is 200 rpm and the time is 10 minutes to ensure uniform dispersion of the solid components; in the wet mixing and stirring stage, the solvent is slowly added, the rotation speed is adjusted to 400 rpm, and the time is 25 minutes to form a uniform paste.

[0030] Preferably, the granular finished product is purple or gray, the particle size distribution is 100 - 500 microns, the dissolution time in water at 25 °C is less than 3 minutes, and the pH value of the solution is controlled between 12.6 and 13.

[0031] Preferably, the decomposition rate of the finished product for heavy oil stains at room temperature is ≥ 95%, and the corrosion rate for metal substrates is ≤ 0.05 mm / year.

[0032] The beneficial effects of the present invention: The food - grade granular sodium hydroxide in the formula of the present invention, by virtue of its strong alkalinity, undergoes a saponification reaction with grease, can effectively decompose heavy - oil dirt. Sodium metasilicate pentahydrate plays a role in dispersion, emulsification and corrosion inhibition, assisting sodium hydroxide to strengthen decontamination. Whether it is the oil stains on hotel purifiers, range hoods or the stubborn stains on the surface of factory machinery, it can be efficiently removed. The components work synergistically, making the foaming agent applicable to different places such as hotels, shopping malls, factories, etc. Whether it is the oil stains on the ground, walls or various domestic and industrial equipment, it can play an excellent cleaning role, and there is no need to replace cleaning products for different scenarios.

[0033] Traditional cleaning products need to be prepared with hot water or boiling water. This foaming agent only needs to add normal - temperature water, greatly simplifying the use steps and saving the preparation time. Users do not need to prepare special heating equipment and utensils. In the domestic and household appliance cleaning industries, when used for the disassembly and cleaning of hotel purifiers and range hoods, it can quickly decompose oil stains, reduce the soaking and cleaning time, and greatly improve work efficiency.

[0034] Using food - grade granular sodium hydroxide, combined with sodium metasilicate pentahydrate, CAB - 35 coconut oil amide propyl betaine surfactant, etc., reduces the corrosiveness of the product. Compared with traditional products mainly based on Junzheng caustic soda and caustic soda, it causes less damage to equipment and objects, reducing the risk of equipment corrosion, discoloration and damage.

[0035] Add lemon essence, which can effectively reduce the pungent smell, reduce the harm to the human respiratory tract, improve the working environment, and reduce the health risks of long-term use. At the same time, add sunset yellow pigment to make the product show purple or slightly gray granular on the surface, with eye-catching appearance, easy to identify and distinguish, and improve the product recognition.
