核桃殼簡介
?
? ? ? 一、特性
??核桃殼是一種經脫脂、破碎、篩選等處理加工過的顆粒狀，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，用它做磨料不會破壞工件表面、拋光效果好等優點：
?1、抗壓能力強 粒徑為1.25-1.60mm的核桃殼粒，平均抗壓極限為0.2295KN。粒徑為0.80-1.00mm的核桃殼粒，平均抗壓極限為0.165KN。
?2、化學性質穩定 核桃殼濾料由于本身的硬度，理想的比重、多孔和多面性，并經特殊的物理化學處理，使它在水處理中具有較強的除油性能，除固體微粒，易反洗等優良性能， 核桃殼濾料已廣泛用在油田含油污水處理、工業廢水處理和民用水處理。是取代石英砂濾料，提高水質，大幅度降低水處理成本的新一代濾料。經研究測定，抗壓能力強粒徑為1.25-1.60mm的核桃殼粒，平均抗壓極限為0.2295KN。粒徑為0.80-1.00mm的核桃殼粒，平均抗壓極限為0.165KN。化學性質穩定，不含有毒物質，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，不會引起水質惡化現象。
?
? ? ? 二、工業應用
?? 1、核桃殼濾料是采用優質的山核桃殼作原料,經過破碎、拋光、蒸洗、**處理,兩次篩選加工而成的一種水處理濾料。核桃殼濾料具有硬度高、耐磨損、抗壓性好,抗壓力為23.4kgf,化學性能穩定，不在酸堿中溶解、吸附截污能力強，吸附率為2750，親水性好，抗油浸等優點。
??核桃殼濾料廣泛應用于油田、化工、制革等工業污水處理及城市給水排水工程，是各種過濾器**理想的水質凈化過濾材料。
??2、核桃殼拋光材料主要應用與眼鏡配件、珍珠首飾、紐扣、電子元器件、沖壓件等的拋光、去毛刺。

Introduction to walnut shell?features
Walnut shell is a kind of degreasing, crushing, screening and other processing processed particle, surface pores, adsorption filter material with better effect, is also a natural rolling light material and polishing abrasive, abrasive use it do not destroy the workpiece surface, and the advantages of good polishing effect:
1. The compressive strength of the particle size is 1.25-1.60 mm, and the average compressive limit is 0.2295 KN . The average compressive limit was 0.165 KN .
2, stable chemical properties Walnut shell filter material due to the hardness of itself, the proportion of ideal, porous and multifaceted, and the special physical and chemical treatment, the pigment, fat, oil, electric ion removal clean), make it has strong oil removal in water treatment performance, in addition to the solid particles, easy backwashing excellent properties, such as walnut shell filter material has been widely used in oilfield oily wastewater treatment, industrial wastewater treatment and civil water treatment. It is a new generation filter which replaces quartz sand filter material, improves water quality and greatly reduces the cost of water treatment. The average compressive limit was 0.2295 KN . The average compressive limit was 0.165 KN . Chemical properties of stability, do not contain toxic substances, dissolved in acid, alkali, water volume is small, loss of walnut shell in hydrochloric acid solution was 4.99, the attrition rate of 3.8 in sodium hydroxide solution, does not cause water quality deterioration.
Ii. Industrial application
1. Walnut shell is used as raw material of high quality mountain walnut shell. It is processed by crushing, polishing, steam cleaning and drug treatment. Walnut shell filter material has high hardness, good wear resistance, pressure resistance, resistance to pressure is 23.4 KGF, stable chemical performance, not in the acid and alkali dissolution, adsorption section carrying capacity is strong, the adsorption rate of 27-50, good hydrophilicity, oil resistance, etc.
The walnut shell filter is widely used in oil fields, chemical industry, leather making and other industrial wastewater treatment and urban water supply and drainage engineering, which is the ideal water quality filter material for various filters.
2. Walnut shell polishing material mainly applied in polishing and deburring of glasses accessories, pearl jewelry, buttons, electronic components, stamping parts, etc.
