聚合氯化鋁的小試一般是先將聚合氯化鋁配置成5%濃度的水溶液來進行實驗。通常為了方面可以稱
days without damaging the strength. It can be used in pumping concrete, high fluidity concrete, mass concrete and high strength functional concrete.
Glucose powder can be used as cement admixture: When a certain amount of glucose powder is added to the cement, the plasticity and strength of concrete can be added, which can retard the beginning and final condensation period of concrete. For example, adding 0.15% sodium gluconate can extend the initial condensation time of concrete by more than 10 times, that is to say, it can delay the beginning and final condensation period of concrete. The plasticity time of concrete is extended from several hours to several days without affecting its fastness.
水泥中添加必定數量葡萄糖粉后，可添加混凝土的可塑性和強度，且有阻滯作用，即推遲混凝土的開始與終究凝聚時期，例如添加0.15%的葡萄糖粉，可將混凝土的初凝聚時間延伸10倍以上，也就是將混凝土的可塑時間從幾小時延伸至幾天，而不影響其牢度。可塑性與推遲開始凝聚時間在混凝土作業中是非常重要的問題，如在高溫度季節施工及大型的工程作業
中，推遲開始凝聚時間則是個難題，葡萄糖粉可圓滿解決這個問題。別的高溫時膠接油井是比較困難的，添加了葡萄糖粉后的混凝土在170℃高溫下，在幾個小時內可塑，因此也能圓滿解決上述問題。因此葡萄糖粉作為水泥摻合劑在國外已許多使用于重要的建筑工程，如中東的許多橋梁工程中。但是我們國內在這方面使用也還未太廣泛，據說有在造紙廢水中提煉纖維素磺酸鈉，其作用與葡萄糖粉根本是不可相提并論的。The plasticity and strength of concrete can be added after adding a certain amount of glucose powder to cement, which has a retarding effect. That is to say, delaying the beginning and final cohesion period of concrete, such as adding 0.15% glucose powder, can extend the initial cohesion time of concrete by more than 10 times, that is to say, delaying the plasticity time of concrete from several hours. Extend to a few days without affecting its fastness. Plasticity and delaying the start of condensation time are very important problems in concrete work. For example, in high temperature season construction and large-scale engineering work, delaying the start of condensation time is a difficult problem, and glucose powder can solve this problem satisfactorily. It is difficult to bond oil wells at other high temperatures. The concrete added with glucose powder can be plastic in a few hours at 170 C, so it can solve the above problems satisfactorily. Therefore, as a cement admixture, glucose powder has been used in many important construction projects abroad, such as many bridges in the Middle East. However, the use of sodium cellulose sulfonate in this field is not very extensive in our country. It is said that sodium cellulose sulfonate is extracted from papermaking wastewater, and its effect is not comparable to that of glucose powder.
聚合氯化鋁PAC處且腐蝕性較小。在實際生產和使用中，操作簡單，水處理效率高。聚合氯化鋁結合各種特性已成為主s. The main difference is that the quality of PAM is not the same, or the way of adding it is not right, otherwise the product is not matched with the type of wastewater. The quantity of polyacrylamide with good quality is less, and the amount of polyacrylamide with minor addition is slightly more. The specific point is about 1-3 grams. Hohhot City accords with the general municipal wastewater. The industrial wastewater is slightly higher, about 3-6 grams, and the highest 10 grams are also available.
Our answer is only a rough estimate and a budget, but the exact amount should be calculated according to the actual object. The technology will compose 0.1-0.5% solution, and then determine the project dosage in a small scale. Four-thousandths of the 1,200-15 million parts of polyacrylamide wastewater treatment will be compounded with 7-10 grams of monosodium glutamate per ton, layer slag of brewery, wastewater and so on. We can see from the above, in addition to the help of manufacturers to choose polyacrylamide, when using their own, we should pay attention to the use of polyacrylamide. Let's simply remember the following points. Dissolution equipment is required. Concentration should not exceed five thousandths when dissolving. If the equipment is a very simple dissolving pot, we should pay attention to adding 20% of the volume of water in the tank first, then polyacrylamide and water into the tank at the same time, and polyacrylamide should be poured into the tank at a uniform speed, not too much at one time. Otherwise, fish eyes and other phenomena will occur.
我們的回答只是個大概和預算，具體多少還 是要根據具體的實物來測算。技術會配成0.1~0.5%溶液，然后小試確定工程用量，聚丙烯酰胺的污水處理1200-1500萬千分之四配每噸用7-10克味精、啤酒廠 層渣、廢水等。我們從上面看出，除了廠家幫忙選購聚丙烯酰胺，自己在使用時候，要注意聚丙烯酰胺的使用方法。我們只要簡單的記住以 下幾點。要有溶藥設備。在溶解的時候濃度設定不要超過千分之五。如果設備是很簡易的溶藥罐的話，要注意在人工加藥時，要先加20%罐體積的水，然后聚丙烯酰胺和水同時進罐，并且聚丙烯酰胺要勻速的向里面傾倒，不要一次性加的太多。否則會產生魚眼等現象
