混合にはポットライフについて考慮されるべきである。The above-mentioned silicate, cyclic carbonate, and salts of sulfamic acid and/or sulfamic acid may be mixed when injected into the soil, or may be mixed before being injected into the soil. . However, pot life should be considered for mixes that are mixed before being poured into the soil.

障される。That is, when mixing all three of the above components, it is necessary to consider the gelation time and mix immediately before the soil is injected, and the cyclic carbonate, sulfamic acid and/or
If the silicates are mixed with salts of sulfamic acid or sulfamic acid and the silicate is kept separate, a certain length of pot life is guaranteed.
本発明の土壌処理剤は土壌に注入されて下記の反応を行

縮せしめる。That is, the cyclic carbonate is hydrolyzed in the presence of water due to the alkalinity of the silicate to generate carbonic acid. The carbonic acid reacts with the silicate to form a carbonate, and gel-like silicic acid is precipitated. Salts of sulfamic acid and/or s/l/7 amino acids accelerate the gelation reaction and shorten the gelation time.

であることもあいまって極めて取扱い易いものである。As described above, the present invention enables the gelation reaction of silicate with cyclic carbonate to be carried out using sulfamic acid and/or sulfamic acid.
The gelation time is promoted by salts of /7 amino acids, and salts of /7 amino acids and sulfuric acids shorten the gelation time to the same extent as conventional inorganic acids and their salts.
It has low hygroscopicity and is difficult to degenerate, so it can be easily stored for long periods of time. It is also highly corrosive, so there is little risk of damaging workers or corroding equipment and instruments, and it is a powder. In addition, it is extremely easy to handle.
更にスルファミン酸やスルフ１ミン酸の塩類は上記した
ように腐蝕性が小さく１００％近い濃度で・安全に取扱
いが出来るから添加量も少なくてすみ輸送、保管にも好
都合である。Furthermore, as mentioned above, salts of sulfamic acid and sulfamic acid are less corrosive and can be safely handled at concentrations close to 100%, so the amount added is small and convenient for transportation and storage.
