硅藻土纯度≥60%的摆件吸湿速率明显更高，纯度低于40%多为普通黏土掺硅藻土，吸湿功能形同虚设，购买时可看密度指标：真硅藻土密度低（0.5-0.9g/cm³）拿在手上明显轻

Unverified硅藻土纯度越高吸湿越强，但纯度过高、密度过低会导致质地酥脆易掉粉开裂，密度适中（约0.6-0.8g/cm³）兼顾吸湿与耐用87% similarUnverified硅藻土纯度≥85%且未添加大量石膏黏合剂的摆件吸湿速度更快，判断方法是滴水后水珠5秒内被吸收无残留水渍81% similarUnverified硅胶干燥剂吸湿量约为自重的20-30%，生石灰（氧化钙）可达自重的28-33%且能吸至更低湿度，蒙脱石（矿物）约20-25%；密闭大容量粮食储存选生石灰或蒙脱石效率更高79% similarUnverified硅藻泥地垫的核心指标是吸水速率，优质产品可在数秒内吸干表面水渍，但吸水后需自然阴干恢复，不可暴晒或水洗（水洗会堵塞微孔失去吸水性）78% similarUnverified生石灰干燥剂吸湿量可达自重的30%-100%，远高于硅胶（约自重20%-35%），适合粮食、大米、干货等高湿度、大空间、长期存储场景76% similar
