江苏离子交换树脂设备图纸¥安微离子交换树脂设备价格【微笑服务】
几乎每个人都知道,人总不能无所事事,人生必须有目标,必须采取行动!但是,聪明人的人知道,目标必须切合实际,行动也必须积极有效。不能为了出风头或一时痛快而不顾可能产生的不良后果。
在我们的习惯性思维,一般不会放弃表示特别的偏好,不轻易放弃生命作为一个固定的哲学。有许多人在面临选择的总是不愿放弃,结果孤注一掷。把握时机,保持一个清醒的头脑,学会选择,学会放弃。只有学会选择,懂得放弃,懂得生活,有海阔天空的人生境界。
江苏离子交换树脂设备图纸¥安微离子交换树脂设备物理性能(1)外观 Resin is a transparent or translucent material, its composition is different, different colors, such as styrene resin is yellow, there were black and rufous, but had little effect on performance, under normal circumstances, raw material impurities or crosslinking agent, resin in a slightly darker shade ( but the resin in the process of operation, for various reasons, sometimes the color will change ). Resin shape is spherical, required circular rate achieves 90% above.
(2)粒度 Ion exchange resin particles size will influence the switching speed, pressure loss, backwash effect. Particle size cannot be too big. Water treatment ion exchange resin particles to20-40is appropriate, granularity of representation to the effective size and uniformity coefficient to express.
(3)密度 关第到水处理工艺和树脂装填量,密度的表示方法有:干真密度(一般1.6g/cm3左右)、湿真密度(一般1.04-1.30g/cm3之间)、视湿密度(一般在0.60-0.80g/cm3之间)。(4)含水率 树脂的含水率越大,表示孔隙率越大,交联度越小。(5)溶胀率 Resin immersion after swelling, it and the crosslinking degree, active groups, exchange capacity, water electrolyte density, exchangeable ion properties etc.. Exchange and regeneration of ion exchange resin in the process of expansion and shrinkage phenomenon occurs repeatedly, expansion and contraction of resin is easy to rupture。(6)耐磨性 反映树脂的机械强度,它应保证每年树脂耗量不超过7%。(7 )溶解性 树脂内含有低聚合物要逐渐溶解,在树脂使用过程中也会发生胶溶。(8)耐热性 Yang Shuzhi temperature of 100degrees&nbs
