查询词典 covered with dust

In addition, there are bond areas between the new and the primary coverage because of the growing up of the plating coat, which may lead to the emergence of micro crack on the coating owing to such causes as too big or uneven impact during plating process, little distortion of global granular zinc dust inside the plating coat, less tight coalescence of the zinc dust flecks.

由于形成镀层的过程处在酸性环境，在镀层增厚过程中不可避免把酸性溶液包裹在镀层里面，酸性溶液会与金属基体和镀层反应，产生氢气，必然会寻找通道选出，形成微气孔；镀层是逐渐形成的，新生镀层与原有镀层之间存在结合面；镀覆过程由于撞击力过大或者不均匀，镀层内部球形颗粒状锌粉变形较小，球形颗粒与球形颗粒的结合不严密等，这些原因会导致镀层产生微裂纹。

The invention discloses a synthetic using method of smelting high-furnace dust, which comprises the following steps: grinding the high-furnace dust with 1.5-15% zinc; proceeding magnetic cobbing; reclassifying to obtain the refined ferric ore; disposing ore tail through waste acid of titanium dioxide with 15-30% sulphuric acid; transmitting the zinc oxide in the solution at zinc sulfate pattern; separating solid and liquid solution through lime; obtaining refined zinc ore through S2-, CO32-, HCO3- ion; floating the immersed slag through neutral oil.

一种炼铁高炉炉尘资源综合利用的方法，含锌1.5％～15％的高炉炉尘经磨矿、磁选、重选回收铁矿物获得铁精矿，选矿尾矿用含硫酸15％～30％的钛白废酸处理，使其中的氧化锌以硫酸锌的形式转入溶液中，固液分离得出的溶液用石灰中和除铁后，再用S2-、CO32-、HCO3-离子沉锌获得锌精矿，浸出渣用中性油浮选获得炭精矿。该方法将钛白废酸和高炉炉尘结合在一起，使之成为互为所需的原料和试剂，有效地将两种废弃物变成了有价资源，较好解决了环境污染问题，同时又能产生好的经济效益。

In filtering dampish gases or gases containing sticky dust, the tendency of dust adhering to the filter bag has long been a difficulty of the industry until the engineers tried to replace the regular filter bag with tectorial filter bag or filter bag processed water-repellent.

利用袋式除尘器处理含湿量大或粘性较大的含尘气体，粉尘易粘附布袋一直是令除尘界头痛难题。国外曾尝试试用覆膜滤袋和对滤材表面进行防水处理解决防结露和布袋糊袋的难题，取得了明显的效果。

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.

结果表明，烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的，当其浓度大于50×10^(-6)时，需要进行烟气脱硫或控制培养液pH变化来消除其影响；烟气中NO浓度不高于300×10^(-6)时，不影响ZY-1的生长及其对CO2的固定，反而可作为氮源供ZY-1生长用；对经过一般除尘处理的烟气来说，在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。
