Abstract
The invention provides a sodium hypochlorite stabilizer, which is provided with a liquid combination form or a solid combination form. Solid stabilizer comprises the following substances in parts by weight: 1 to 4 parts of sodium phosphate, 1 to 3 parts of disodium hydrogen phosphate, 1 to 3 parts of sodium dihydrogen phosphate and 3 to 7 parts of sodium silicate; the liquid combination form comprises 9 to 13 parts of water on the basis of the solid stabilizer. Four substances are prepared in a given proportion, so favorable factors are maximized and unfavorable factors are minimized, and advantages of each substance are maintained, weaknesses of each substance are overcome, so the stability of the sodium hypochlorite solution can obtain a satisfactory effect.
Description
Technical field
The present invention relates to a kind of sodium phosphate, sodium hydrogen phosphate, sodium dihydrogen phosphate and stabilizing agent specially used method of sodium silicate co-production clorox used, belong to the disinfectant technical field.
Background technology
Clorox (NaClO) is a kind of mineral salt of using widely, also is a kind of strong oxidizer, bleaching agent, disinfectant and deodorant.Aqueous sodium hypochlorite solution is commonly called as drift ice, is the by product of chlorine industry, is mainly used in the bleaching of paper pulp, fabric etc., the processing of water up and down, and the sterilization of hospital, the catering trade, hotel and family and sterilization also are the important raw materials of industry.Present commercially available industrial clorox is the aqueous solution of efficient 〉=10% often, and aqueous sodium hypochlorite solution at normal temperatures natural decomposition can take place.In addition sunshine, be heated, acid and heavy metal ion all can cause aqueous sodium hypochlorite solution to decompose, and only is 1 day in summer with temperature effective storage period that raises.So the range of goods of this product is restricted: product causes easily and sells shortage generally only in its production area in 300 kilometers, and deposits and lose effect for a long time, promptly causes economic loss contaminated environment again.Therefore, exploration and exploitation liquor natrii hypochloritis's stabilization technique is very important.
Improve industrial liquor natrii hypochloritis's stability, can remove from production technology, liquor natrii hypochloritis's pH value, impurity metal ion, condition of storage improves and add several aspects such as stabilizing agent takes in.Wherein in the liquor natrii hypochloritis, add stabilizing agent and be method eaily.Common stabilizing agent has inorganic stabilizers and organic stabilizer.The adding of organic stabilizer influences the liquor natrii hypochloritis as the application of raw material in chemical reaction, the big and DeGrain of single inorganic stabilizers adding proportion.This paper probes into by experiment and seeks a kind of compound stabilizer that can effectively improve liquor natrii hypochloritis's stability for this reason.
Summary of the invention
The objective of the invention is to sodium phosphate, sodium hydrogen phosphate, sodium dihydrogen phosphate and sodium silicate co-production clorox stabilizing agent specially used.
Technical scheme of the present invention is achieved in that
The clorox stabilizing agent comprises two kinds of combining forms of liquid or solid:
The agent of clorox Pickering is made up of following substances in parts by weight: sodium phosphate 1-4 part, sodium hydrogen phosphate 1-3 part, sodium dihydrogen phosphate 1-3 part, sodium silicate 3-7 part.Preferred group becomes: 2 parts of sodium phosphates, 1 part of sodium hydrogen phosphate, 1 part of sodium dihydrogen phosphate, 5 parts of sodium silicate.
The liquid combination form of clorox stabilizing agent is to add a part of water on the basis of Pickering agent, and ratio of weight and number is: sodium phosphate 1-4 part, and sodium hydrogen phosphate 1-3 part, sodium dihydrogen phosphate 1-3 part, sodium silicate 3-7 part, water 9-13 part, but be preferably 11 parts.
In the aforementioned stable agent was formed, the aqueous solution alkalize of sodium silicate can reduce the H concentration in the solution, prevent that hypochlorite from becoming hypochlorous acid with the H ions binding in acid solution, like this, both reduced the H concentration in the solution, increase solution PH again, reached the effect of stablizing clorox.Simultaneously, sodium silicate can also adsorb hypochlorous acid is decomposed the metal ion that catalytic action is arranged, to corrosion of metal.Weak point is to generate insoluble silicate with calcium, magnesium plasma, deposits hard silicon dirt on equipment and fabric.
And sodium phosphate and hypochlorous acid interact, a kind of double salt Efficacious Disinfeitant with water of crystallization of generation.It is very desirable, rare nontoxic, efficient, the Rapid Cleaning disinfectant of bleaching, sterilization and the antiseptic property of a kind of washing detergency ability that has sodium phosphate concurrently and clorox.Can remove the silicon dirt.
Sodium hydrogen phosphate and sodium dihydrogen phosphate are strong buffer, can be effectively with the liquid stable in the medium in certain pH value scope, with control with keep stable PH excursion.
Though above four kinds of materials can be separately as the stabilizing agent of clorox, effect is not really desirable, and the present invention is composite by a certain percentage with four kinds of materials, maximize favourable factors and minimize unfavourable ones, kept advantage separately, overcome deficiency separately, made the liquor natrii hypochloritis aspect stable, can obtain satisfied effect.
The preparation method of described clorox Pickering agent is, is mixed evenly with each composition of clorox Pickering agent is dried, fully grinds and gets final product; Using method is directly to add in the liquor natrii hypochloritis, and the part by weight of adding is liquor natrii hypochloritis's 0.1-0.5%.
The preparation method of described clorox liquid stabilizing agent is: be mixed evenly with each composition of clorox Pickering agent is dried, under stirring condition, be distributed to gradually again
Water in get final product.Using method is directly to add in the liquor natrii hypochloritis, and additional proportion is liquor natrii hypochloritis's 0.5-1.0%.
Clorox stabilizing agent of the present invention can effectively guarantee the steady quality of aqueous sodium hypochlorite solution.
