じて使い分けられている。A soil stabilizing solution based on an alkali silicate solution reacts with a hardening agent to precipitate a silicate gel from the alkali silicate, which improves the ground and achieves the intended purpose. A large number of hardening agents that can precipitate silicate gel from alkali silicate have been proposed so far, and they can be roughly divided into inorganic compounds and organic compounds.The other types are acids, acid salts, These curing agents are classified into polyvalent metal salts, esters, dialdehydes, etc. Each of these curing agents has its own characteristics. Therefore, when trying to improve the performance of curing agents, multiple types are used in combination, and Different agents are used depending on the purpose.

、汎用性がない。Among these, carbonated alkalis (specifically potassium bicarbonate and sodium bicarbonate) are taken up as the main components of the curing agent, and in order to increase the strength of the resulting gel, a small amount of water-soluble magnesium salt is added. Mixed aqueous solutions of salts are relatively unstable, and within a short time after preparation, water-insoluble magnesium compounds can form scales on tanks, bonders, pulp, hoses, and injection equipment at Cape Ronde, reducing work efficiency. Disturbing things happen. Although there are other curing agent liquids that do not generate such scale, they are not versatile because they are strong acids and are expensive.

る。Alkali hydrogen carbonate is widely admired because it is a safe compound that does not cause any harm to the human body or even plants and animals, and is approved as a food additive, but the strength of the gel it produces is The problem is that when a water-soluble magnesium salt is used in combination to increase the strength, the above-mentioned drawbacks occur. In other words, if less than 20% by weight of water-soluble magnesium salt is used in combination with alkali hydrogen carbonate, a silicate gel with high strength and good water resistance can be obtained. Mixed aqueous solutions are unstable and difficult to use, and there is a strong desire to improve this in the drug injection industry.

レングリコールジアセテートなどである。Examples of additives that improve this stability include water-soluble lower alkylene carbonate (JL), ethylene carbonate, propylene carbonate, and the like. Second are the alkali salts of water-soluble oxyacids, specifically the alkali salts of citric acid, tartaric acid, malic acid, lactic acid, guconic acid and glycolic acid. Further examples include alkali salts of polyacrylic acid, urea, alkali sulfates, glyoxal and ethylene glycol diacetate.
トの内のエチレンカーボネートであり、硫酸アルカリ塩
のうちの硫酸ナトリウムである。これ等を用いることに
より硬化剤の安定性を特に顕著に改善できる。Of these, ethylene carbonate is one of the salts, and sodium sulfate is one of the alkali sulfate salts. By using these, the stability of the curing agent can be particularly significantly improved.

５０〜２００のものが効果的である。Further, polyacrylic acid having a polymerization degree of 5 to 5,000 is used, preferably 20 to 2,000, more preferably 50 to 200, which is effective.

２０重量−未満普通には１５重量％未満であることが多

ので好ましくない。When alkali hydrogen carbonate is used as a main component as a curing agent for injection liquids for ordinary purposes, it is used at a concentration of 4 to 10 degrees SS by weight in the liquid medicine. When a magnesium salt is used in combination, magnesium sulfate or magnesium chloride is often used, but since the latter is significantly deliquescent, the former is preferred. The amount used is often less than 20% by weight of the alkali bicarbonate, usually less than 15% by weight, for normal purposes; use of a large amount is undesirable because it produces a heterogeneous silicic acid gel.

沈澱の生成が始まる。However, if this combination of curing agent is used without the above-mentioned additives, the water-insoluble magnesium compound will begin to precipitate in the aqueous curing agent solution in 2 to 4 hours, depending on the amount of magnesium salt added, water temperature, etc.
この傾向は水溶液を攪拌している時程著るしい。This tendency is more pronounced when the aqueous solution is stirred.
