水處理用核桃殼過(guò)濾器濾料出口技術(shù)標(biāo)準(zhǔn)參考

1. 等級(jí): 12/16

2. 特性: 比重: 1.48;   pH 值 25 °C (在水中) : 4 -6;   游離水分 (80 °C for 15 HRS):  3-5 %;   閃點(diǎn) (閉杯實(shí)驗(yàn)): 193 °C; 硬度-維克氏硬度: 25-30; 莫氏硬度: 3- 4; 干包裝密度（磅/立方英尺): 45; 彈性模量: up to 21,000 psi  

3. 化學(xué)分析 氮: 0,10; 纖維素: 46/60; 木質(zhì)素: 20/30; 甲苯溶解度 : 0,5/1,0; 甲氧基: 6,5; 氯: 0,10; 灰: 1,5; 角質(zhì): 1,0;

以上參數(shù)只做參考不作為硬性指標(biāo)，實(shí)際使用參數(shù)會(huì)根據(jù)操作使用環(huán)境的改變而改變。水質(zhì)水量及出水水質(zhì)要求不同，對(duì)粒徑等級(jí)的要求會(huì)有所改動(dòng)，但產(chǎn)品本身的物理特性和化學(xué)特性沒有太大變化。

The above parameters are for reference only and not as rigid indicators. The actual use parameters will change according to the changes in the operating environment. The requirements for water quality and effluent quality are different, and the requirements for particle size levels will be changed, but the physical and chemical properties of the product itself have not changed much.
