一、造粒工艺及方式

•Pressure – extremely high (cannot use liquid or low melting point actives)
压力---非常高(不能用液体、低熔点原药)
•Water – no; yes for tabletting水---没有;压片有
•Binder – not necessary for compaction; yes for tabletting
粘结剂---压制成型不需要;压片需要
•Unique inerts – lubricants (tabletting), disintegrants (tabletting), effervescing agents (tabletting)
独特的惰性成分----润滑剂(压片),崩解剂(压片),泡腾剂(压片)

二、造粒粒子的要求?
•Why is agglomeration strength important? 为什么团聚强度是重要的?
••Agglomeration strength relates to two very important WDG properties
团聚强度与WDG两个很重要的性能指标息息相关
•1.Friability – does the granule fall apart during handling (processing, packaging and transportation)
易碎性---粒子处理过程中的破碎程度(加工,包装和运输)
2.Dispersability – how easily the WDG disperses when diluted in water
分散性---用水稀释时,水分散粒剂散开的难易程度
3. For optimum WDG performance there has to be a balance between the two为使水分散粒剂的性能最佳化必须调节易碎性和分散性的平衡
四、水分散粒剂WDG典型造粒配方
•Typical extrusion formulation 典型挤压造粒配方
Pesticide active农药含量- 80.0%
Dispersant 分散剂- 7.5%
Wetting agent 润湿剂- 2.5%
Silica 二氧化硅- 1.0%
Filler 填料- to补足100 %
Binder solution (water) - 15% needed for granulation
造粒时需15% 粘合剂(水)溶液
Formulation “Trick”配方“决窍”
•Typical extrusion formulation 典型挤压造粒配方
•Pesticide active 农药含量- 80.0%
Dispersant 分散剂- 7.5%
Wetting agent 润湿剂- 2.0%
Silica 二氧化硅- 1.0%
Filler 填料- to补足100%
Binder solution (10% wetting agent solution) -粘合剂溶液( 10%润湿剂溶液)
7% needed for granulation (50% less water) - 7% 造粒需要( 50% 不用水)
Other advantages: Quicker wetting 快速润湿
其他优点 Faster dispersion 迅速分散
Less friable 不易碎
