Claims (5)
- 유동상태로 유지된 과탄산 나트륨 입자위에 붕산수용액과 알칼리 금속 규산염 수용액을 각각 분무하여 과탄산 나트륨 입자를 붕산과 알칼리 금속 규산염으로 코팅함을 특징으로 하는 안정화된 과탄산 나트륨의 제조방법.
- 제1항에 있어서, 붕산 수용액의 농도가 그의 포화수용액 농도의 10~95%이고 알칼리 금속규산염 수용액 농도가 SiO2로 환산하여 5~50 중량%인 안정화된 과탄산 나트륨의 제조방법.
- 제1항에 있어서, 붕산의 양이 과탄산 나트륨에 대해 0.3~20 중량%이고, 알칼리 금속 규산염의 양이 과탄산나트륨에 대해 SiO2로 환산하여 0.1~10 중량%인 안정화된 과탄산 나트륨의 제조방법.
- 제1항에 있어서, 코팅될 과탄산 나트륨 입자의 평균 입자직경이 100~2,000㎛인 안정화된 과탄산 나트륨의 제조방법.
- 제1항에 있어서, 과탄산 나트륨의 온도가 30~100°C로 유지되는 안정화된 과탄산 나트륨의 제조방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
