Problems solved by technology

②Because the pH value of 4A zeolite is neutral, it cannot meet the alkalinity required by the detergent, and some alkali must be added when using it, which increases the production cost of the detergent
③4A zeolite is a solid substance insoluble in water, without suspension and dispersion properties, so the washing powder produced by it will produce crustaceous calcium deposits during washing, causing secondary pollution to the laundry or difficulty in rinsing
In order to alleviate this deficiency, the dispersant sodium citrate has to be added, which increases the production cost

example 1

[0022] Example 1. Dissolve the above-mentioned layered polymeric bicrystalline sodium aluminosilicate double salt with soft water into a saturated solution, take 1kg of the saturated solution, add sulfuric acid to control the pH value to 9.5; add a little sodium carboxymethylcellulose (to reach the required concentration ); then add anionic surfactant alkylbenzene sulfonate sodium salt 2wt%, essence 0.1wt%.

example 2

[0023] Example 2, before the same example 1, add sulfuric acid to control the pH value at 10.6; add some sodium carboxymethylcellulose, then add anionic surfactant alcohol sodium sulfate double salt 0.7%, lemon essence 0.1wt%.

example 3

[0024] Example 3, the same example 1 above, add sulfuric acid to control the pH value at 10.6; add a little sodium carboxymethylcellulose (so far as to reach the required viscosity), then add 0.7% anionic surfactant ethylene oxide or dodecane base alcohol, lemon essence 0.1wt%.

[0025] (2) Make washing powder (by weight percentage)

Abstract

The present invention relates to detergent, and discloses one kind of detergent without surfactant, soap, phosphate and 4A zeolite. The detergent is complex salt of sodium aluminosilicate and may be named as Na-P type detergent molecular sieve. It is prepared with flyash as main material, and through alkalization with sodium hydroxide to produce sodium silicoaluminate colloid, further reaction with limestone powder and coal gangue powder, ageing in alkali solution and roasting to obtain the quick soluble white crystal complex salt. The detergent may be further compounded into washing agent, washing powder or defatting agent with less pollution to water source. The present invention is environment friendly and low in cost.

Description

technical field [0001] The invention belongs to the scope of cleaning products, in particular to a non-surface active non-soap cleaning product without phosphorus and 4A zeolite, which is made from waste fly ash of power plants. Background technique [0002] Washing products of the prior art, such as washing liquid, washing powder and degreasing agent are usually made of sodium tripolyphosphate, sodium sulfate, sodium metasilicate, sodium hydroxide, surfactant (such as sodium lauryl sulfonate), non- Surfactants and other series are mixed, and some have a certain leg color, burn hands or have a corrosive effect on furniture, especially products containing phosphide, which are one of the biggest natural enemies that damage water resources. The United Nations Paris Conference has It is proposed to ban the washing products made of phosphide in 2000. So people began to use 4A zeolite instead of phosphate. ①The reason why this substance can soften water is that the diameter of th...
