Unverified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）87% similarUnverified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81% similarUnverified硅藻土吸水快干得也快（表面水分几十秒扩散），但踩感冰硬无缓冲；微纤维踩感柔软但吸饱后表面潮湿、干燥慢需晾晒，二者不可兼得79% similarUnverified钠基膨润土结团性优于钙基，包装无标注时可用少量水测试：优质膨润土遇水5秒内成团、拎起不散且底部无残留77% similarUnverified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77% similar
