以卤虫卵壳作为材料研究了其保水特点。结果表明 :原始的卤虫卵壳pH值为 6 .5~ 7.0 ,含盐量为3 .38% ;要将原始卤虫卵壳开发为保水剂 ,关键在于降低其含盐量 ,实验表明脱盐过程卤虫卵壳与水以 1∶80的重量比 ,分两次等量冲洗处理可将其含盐量降低到无盐害状态。脱盐处理后的卤虫卵壳的容积吸水比为 0 .95∶1 ;经脱盐处理后的卵壳与土壤等体积配比保水性好
With the brine egg shell as a material to study its water retention characteristics. The results showed that the original egg shell eggshell pH value of 6.5 ~ 7.0, the salt content of 3.38%; to develop the original shell brine shrimp eggshell agent, the key is to reduce its salt content, experiments show that desalination Process Artemia egg shell and water weight ratio of 1:80, divided by two equal amount of flushing treatment can reduce its salt content to salt-free state. The volumetric water absorption ratio of brine shrimp egg shell after desalination was 0.95: 1; the volume ratio of eggshell to soil after desalination was good
