絮散作用 的英文怎麼說
中文拼音 [xùsǎnzuòyòng]
絮散作用
英文
deflocculation-
On the basis of theory analysis, the average transmitted light intensity ( correspond to dc value ) was determined as characteristic parameter of raw water using photoelectric method for monitoring the fluctuation of transmitted light and photometric dispersion analyzer ( pda ). the dc value was closely related to both particle concentration and surface area of sand clay simultaneously. the experimental results shows that there is an exponential function relation between dc and surface area of sand clay in unit volume water ( sp ) : dc = asbp in which a and b are empirical coefficients. then the formula of macromolecule flocculant dosage is found to be d = f ( dc ) = e ( dc ) f in which e and / are empirical coefficients and the average correlation coefficient equal to 0. 981. so the model of automatical control system of water treatment plant was established using the formula
應用透光率脈動檢測技術和光散射顆粒粒度分析儀（ pda ） ，通過理論分析，將pda的輸出信號之一? ?平均透光強度（對應于dc值）作為原水的特性表徵參數， dc值可以同時反映顆粒濃度和比表面積因素的影響，試驗結果證明， dc值與單位體積水中泥沙顆粒總表面積s _ p之間具有很好的冪函數關系： dc = cs _ p ~ d ，式中c 、 d為經驗系數，進而得到了以dc值為參數的高分子絮凝劑投藥量公式： d = f （ dc ） = e （ dc ） ~ f ，式中： e 、 f為經驗系數，平均相關系數達0 . 981 ，利用所建立的公式，建立了前饋? ?后饋聯合控制的在線自動投藥模型。The results showed that the rubber latex particles separated the clay into nanometer units, accompanied with the competition between separation of rubber latex particles and re - aggregation of single silicate layers upon addition of flocculant during the process of co - coagulating, while the intercalation of rubber molecules into clay galleries did not occur
結果表明，在加入絮凝劑使橡膠乳液黏土水懸浮液共凝聚的過程中，由於存在膠乳粒子對黏土片層的隔離作用與在混合液中分散的黏土單片層的重新聚集作用的競爭，因此，在絮凝物中，橡膠大分子將黏土片層隔離成納米分散單元（包括單片層和多片層的聚集體） ，在多片層的黏土聚集體層間沒有橡膠大分子插入。The mean diameter increases with the increase of alum dose, but the fractal dimension does not vary. however, extremely high dose of sluminum results in an increase of floc diameter but a decrease of the fractal dimension. the main reason is the sweep floes is too loose in their structure, and ca n ' t resist the shear force
隨著投藥量的增大，絮凝體分形維數的變化較小，但絮凝體平均粒徑顯著增加；當投藥量過高時，網掃絮凝作用下的絮體結構鬆散，抗剪切能力差，具有較小的平均粒徑和分形維數。When the dosage was 8 % aa, the effect was best. ( 2 ) the performance of pc was decided with the proportion of pea, aa, mma. the fluidity of copolymer would augment if the dosage of aa increase, but when dosage of aa was 75 %, it was hard to control the compose reaction, and dispersion of pc would depress ; when pea degree of polymerization augment the air - entraining of mma would increase ; it would produce floe and hard to control the compose reaction when the dosage of pea4 more than 15 %, pea23 more than 25 %
（ 2 ） pea 、 aa 、 mma之間的比例關系決定了共聚體的性能：隨著丙烯酸用量的增加，共聚體的流動度增大，達到75時合成控制難度加大，共聚體分散性下降；而mma的引氣增穩作用，其用量隨著pea的聚合度的增加而增加， pea4體系的用量超過15 ， pea23體系超過25則會產生絮狀物，反應控制難度加大，理想的用量分別為不超過10和15 。分享友人
