Claims (6)

분말상태의 황산칼륨과 계면활성제를 용해 또는 분산시킨 소량의 물을 혼합한 다음, 당해 혼합물을 압축조립하는 것을 특징으로하는 입상 황산칼륨의 제조방법.A method for producing granular potassium sulfate, comprising mixing powdered potassium sulfate with a small amount of water in which a surfactant is dissolved or dispersed, and then compressing the mixture. 제1항에 있어서, 분말상태의 황산칼륨에 대하여 계면활성제를 0.001내지 20중량% 용해 또는 분산시킨물 0.03 내지 0.1중량를 혼합하는 제조방법.The method according to claim 1, wherein 0.03 to 0.1 wt% of a dissolved or dispersed surfactant in an amount of 0.001 to 20 wt% is mixed with potassium sulfate in powder form. 제1항에 있어서, 계면활성제가 음이온계 계면활성제, 양이온계 계면활성제, 양성 계면활성제 또는 비이온성 계면활성제에서 선택한 1종 이상의 계면활성제인 제조방법.The process according to claim 1, wherein the surfactant is at least one surfactant selected from anionic surfactants, cationic surfactants, amphoteric surfactants or nonionic surfactants. 제1항에 있어서, 황산칼륨이 화칼륨과 황산을 건식으로 반응시켜 수득한 것인 제조방법.The process according to claim 1, wherein the potassium sulfate is obtained by dry reaction of potassium sulfide with sulfuric acid. 제4항에 있어서, 황산칼륨속의 유리황산을 중화시키기 위해 소석회를 압축조립시에 혼합하는 제조방법.5. A method according to claim 4, wherein the slaked lime is mixed during compression assembly to neutralize free sulfuric acid in potassium sulfate. 제1항에 있어서, 로울프레스를 사용하여 압축조립하여 이루어진 제조방법.The production method according to claim 1, which is made by compression assembly using a roll press. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
