本発明は固結が防止された硝酸カリウムまたは亜硝酸カ
リウムの粉粒体組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a granular composition of potassium nitrate or potassium nitrite that is prevented from caking.
硝酸カリウムまたは亜硝酸カリウムの粉粒体は、吸湿性
が高いため貯蔵や輸送の間に固結が起こりやすく、これ
が取り扱い上着しい障害となっている。Powdered materials of potassium nitrate or potassium nitrite have high hygroscopicity and therefore tend to clump during storage and transportation, which poses a serious problem in handling.
従来、このような吸湿性の粉粒体の固結防止方法として
、これらの粉粒体に種々の界面活性剤を配合することが
知られており、例えば、ナ／

！；、３−／！；２９Ｊ ）等が知られている。Conventionally, as a method of preventing caking of such hygroscopic powders, it has been known to mix various surfactants with these powders. For example, sodium naphthalene sulfonate has been used. A method of doing so (Japanese Patent Application Laid-Open No. 2003-120003; 3-/!; 29J) is known.
しかしながら、これらの界面活性剤による固結防止効果
は十分満足できるとは言えず、より大きい効果を得よう
として多量に用いると着色や品質の低下を招くなどの欠
点がある。However, the anti-caking effect of these surfactants cannot be said to be fully satisfactory, and if a large amount is used in an attempt to obtain a greater effect, there are drawbacks such as coloring and deterioration of quality.
本発明は、着色や品質低下がなく、しかも固結が防止さ
れた工業的価値が大きい硝酸カリウムまたは亜硝酸カリ
ウムの粉粒体組成物を提供するものである。The present invention provides a granular composition of potassium nitrate or potassium nitrite that is free from coloration and quality deterioration and is prevented from caking, and which has great industrial value.

果をあげ得ることを見出した。As a result of extensive research into methods for preventing caking of potassium nitrate or potassium nitrite powder, the present inventors found that when using a specific potassium salt type surfactant, a sodium salt type surfactant should be used. It has been found that even though the only difference is in the type of alkali metal, an extremely excellent anti-caking effect can be achieved.

The sample was dropped from a position of rOcm, the fallen material was passed through a sieve with an opening of 3n, and the percentage of the sample remaining on the sieve was shown. The smaller the solidification rate, the lower the degree of solidification.
