2.微囊懸浮-水乳劑（ZW）及微囊懸浮-懸乳劑（ZE）凍融穩定性合格要求為：儲后游離有效成分含量、酸堿度或pH范圍、濕篩試驗、分散穩定性、傾倒性等應符合產品規格要求。
1. Introduction
The pesticide freeze-thaw stability test chamber is designed and manufactured in accordance with NYT 2989-2016 pesticide registration product specifications. It is used for freeze-thaw stability test of microcapsule liquid preparations. The compressor, heating part and power control part are all imported parts with high quality and high performance. The temperature difference of each point in the freezing and thawing box does not exceed 1℃ when operating at full load. Automatic control, real-time dynamic display of data curve, automatic storage of test data, and automatic recovery function for unexpected termination of test.
Freeze-thaw stability tests should be carried out for microencapsulated liquid preparations. The purpose of the test is to ensure the integrity of the capsule when the temperature changes in the encapsulated formulation, so as to ensure the complete release of the active ingredients. The freezing and thawing stability test conditions are 4 cycles between (-10±2)℃ and (20±2)℃, and each cycle is freezing for 18h and thawing for 6h. Microcapsule liquid preparations mainly include microcapsule suspension (CS), microcapsule suspension-water emulsion (ZW), microcapsule suspension-suspension (ZC), microcapsule suspension-suspension emulsion (ZE) and other dosage forms.
1. Qualified requirements for freeze-thaw stability of microcapsule suspension (CS) and microcapsule suspension-suspension (ZC) are: free active ingredient content after storage, pH or pH range, wet sieve test, suspension rate, spontaneous dispersion, Pourability, etc. should meet product specifications;
2. Qualified requirements for freeze-thaw stability of microcapsule suspension-water emulsion (ZW) and microcapsule suspension-suspoemulsion (ZE) are: free active ingredient content after storage, pH or pH range, wet sieve test, dispersion stability, dumping The performance should meet the product specification requirements.
