What is walnut shell?
Walnut shell is a granular material that has been processed through degreasing, crushing, and screening; it features many micro-pores on its surface, making it an effective filter medium and polishing abrasive. Walnut shells contain juglone, hydrogenated juglone, β-glucosides, tannins, gallic acid, and other compounds. 　　Juglone is an orange, needle-shaped crystal with anti-hemorrhagic biological activity. Several reduced derivatives coexist with juglone, all of which possess antibacterial properties and can be used medicinally to treat conditions such as metrorrhagia, mastitis, scabies, psoriasis, and sores; they also have effects in reducing swelling and relieving itching. 　　Characteristics of walnut shells (I) Walnut shell particles with a particle size of 1.25–1.60 mm have an average compressive strength of 0.2295 KN (23.40 kgf). 　　(II) Walnut shell particles with a particle size of 0.80–1.00 mm have an average compressive strength limit of 0.165 KN (16.84 kgf). 　　(III) It has stable chemical properties and does not contain toxic substances; its solubility in acids, bases, and water is very low. The loss of walnut shells in hydrochloric acid solution is 4.99%, while the loss rate in sodium hydroxide solution is 3.8%, so it does not cause deterioration of water quality. 　　Uses of walnut shells 1.
