特性核桃殼是一種經(jīng)脫脂、破碎、篩選等處理加工過(guò)的顆粒狀，表面多微孔、吸附效果較好的濾料，也是天然的滾光材料及拋光磨料，用它做磨料不會(huì)破壞工件表面、拋光效果好等優(yōu)點(diǎn)：（一）抗壓能力強(qiáng) 粒徑為1.25-1.60mm的核桃殼粒，平均抗壓極限為0.2295KN(23.40kgf)。粒徑為0.80-1.00mm的核桃殼粒，平均抗壓極限為0.165KN(16.84kgf)。（二）化學(xué)性質(zhì)穩(wěn)定 不含有毒物質(zhì)，在酸、堿、水中溶解量很小，核桃殼在鹽酸溶液中的損耗為4.99%,在氫氧化鈉溶液中的損耗率為3.8%，不會(huì)引起水質(zhì)惡化現(xiàn)象。工業(yè)應(yīng)用1、濾料產(chǎn)品廣泛應(yīng)用于油田、化工、制革等工業(yè)污水處理及城市給水排水工程，是各種過(guò)濾器較理想的水質(zhì)凈化過(guò)濾材料。2、拋光材料主要應(yīng)用與眼鏡配件、珍珠首飾、紐扣、電子元器件、沖壓件等的拋光、去毛刺。王坤德延津民間驗(yàn)方1、核桃殼煮水治咽炎：嗓子發(fā)炎不光影響吞咽，還會(huì)引起發(fā)高燒等并發(fā)癥。核桃殼煮水喝。具體方法為：準(zhǔn)備洗干凈的核桃殼兩三個(gè)，水1000ml。每天早上將核桃殼放入水中煮，待水開(kāi)后再煮10分鐘即可。每天分兩三次將水喝完，堅(jiān)持半年就有明顯的效果。2、核桃殼煮水治胃潰瘍：核桃殼煮水，**口腔潰瘍、胃潰瘍，核桃殼具有一定的收斂作用，抓一小把核桃殼，大約有50克，煮水，早晚各服一次。3個(gè)月后，胃脹氣、胃潰瘍得到了控制。
