◆酷暑年年有,执扇问青天,为何今年夏季,高温到这般?防中暑,多休闲,心依然。人有悲欢离合,天有冷热四季,此事古难全。但愿好朋友,康乐岁月甜!
◆夏风送去清凉意,夏雨迎来美如昔;夏日蝉鸣东南枝,夏月柔情无所依;夏日周末问候至,夏季荷香谁予寄;夏天蛙鸣寂静止,有朋岁月多美丽。

1)柳州纳滤设备,梧州纳滤膜设备,钦州纳滤设备描述:
1、Nanofiltration membrane device / (NF ) main removal of diameter of 1nm ( nm ) around the solute particles,Molecular weight cut-off of100~ 1000, nanofiltration membrane is a big feature film body with charge, this is it in very low pressure is still high desalination properties and molecular weight cut-off of hundreds of film,Removal of inorganic salt can also be the important reason.
Membrane separation process without any chemical reaction, no heat, no phase change, does not damage the biological activity, does not change the flavor, aroma,So it is more and more widely used in the preparation of drinking water and food, medicine, biological engineering, pollution control and other industries in a variety of separation and enrichment and purification process。
2)柳州纳滤设备,梧州纳滤膜设备,钦州纳滤设备工作原理
膜分离是利用膜对混合物中各组分的选择渗透作用性能的差异,The outside energy or chemical potential difference as a driving force for two-component or multicomponent mixed gas or liquid separation, classification, purification and enrichment method. Membrane pore size in nano level, suitable for separation of molecular weight in 100 ~1000, the molecular size of approximately 1nm of dissolved components of membrane process known as nanofiltration ( NF )。NF膜分离需要的跨膜压差一般为0.5~2.0 MPa,比用反渗透膜达到同样的渗透能量所必需施加的压差低0.5~3 MPa。根据操作压力和分离界限,可以定性地将NF排在反
