溶解性：極易溶于水，略溶于酒精，不能夠溶于Sodium gluconate application:
Concrete is a composite material made of cement, aggregate, admixture and water. Concrete is the most abundant of all manufactured materials. Three quarters of concrete is aggregate, but the most active component in concrete is cement slurry. The properties and properties of concrete mainly depend on the properties of cement slurry. The admixtures in concrete can provide some beneficial effects, such as accelerating solidification, delaying solidification, making air bubbles, reducing water consumption and increasing plasticity, etc. Usually several admixtures are used in cement at the same time, and different admixtures can reinforce each other in some applications.
Sodium gluconate can be used as admixture in concrete. Its function in concrete is
??在平常假如我們常常運用，能夠選擇干粉顆粒狀聚丙烯酰胺，The classification obtained by the method is different. If the ionic type can be divided into Yin, non, amphoteric and cationic polyacrylamide, if according to the shape, it can be divided into four shapes: colloid, laxity, emulsion and dry powder. Which of these four forms is more suitable for us? The company gives you some suggestions. Next is our experience. I hope you will be interested.
In general, if we often use it, we can choose dry powder granular polyacrylamide. Because of its highest solid content, dry powder polyacrylamide is generally stored in dry and cool places for more than two years, but if mixed with solution, its storage time will be limited. Generally speaking, when the concentration of solution is 0.1%, non-ionic and anionic polyacrylamide will dissolve. The stability of cationic polyacrylamide solution depends on the concentration of the solution. For example, the more concentrated the solution is, the longer the storage time of 3%-5% solution is, but the 3%-5% solution can not be directly used to treat sewage. This solution needs to be diluted before use, and the PH value of cationic polyacrylamide solution is less than 5.5. Stability, if greater than 6.0, will be due to hydrolysis and failure, water medium dispersion polyacrylamide shelf life of six months.
Therefore, polyacrylamide is still a better choice of solids, can be used with the mix, do not cause waste.
Of course, we must pay attention to the conditions and taboos of preserving polyacrylamide. Polyacrylamide is more sensitive to iron ions, calcium ions and magnesium ions than anionic polymers. In particular, iron ions are catalysts for the chemical degradation of all polyacrylamide. Therefore, in the manufacture, handling and storage of polyacrylamide solutions, we must try to avoid iron ions entering and touching the solution. The equipment should be made of plastics, stainless steel, FRP or carbon steel with surface coating resin.由于它的固含量，一般情況下干粉聚丙烯酰胺在干燥、陰涼的當地是寄存二年以上的，但假如配成溶液的話，它的寄存時刻就有限了，一般說，溶液濃度為0.1%的時候，非離子與陰離子聚丙烯酰胺溶液不會超過一周的時刻，陽離子聚丙烯酰胺溶液則不會超過一天，而且溶液的穩定性與溶液的濃度有關，配的濃度越濃，例如3%——5%的溶液寄存時刻越長，但3%——5%的溶液不能直接去處理污水，這種在運用前需要稀釋，陽離子聚丙烯酰胺溶液PH值小于5.5的時后比較穩定，假如大于6.0的話，就會由于水解的原因而失效，水介質渙散型聚丙烯酰胺保質期為六個月。
??所以聚丙烯酰胺仍是選用固體的比較好，能夠做到隨配隨用，不造成糟蹋。
??當然大家一定要注意保存聚丙烯酰胺各種條件和忌諱，聚丙烯酰胺對鐵離子、鈣離子、鎂離子比陰離子聚合物質靈敏，尤其是鐵離子是造成所有聚丙烯酰胺化學降解的催化劑，所以在制造、搬運與儲存聚丙烯酰胺溶液的話，一定要盡量避免鐵離子進入與溶液觸摸設備要用塑料、不銹鋼、玻璃鋼或表面涂料樹脂的碳鋼制造。
檢工業葡萄糖在混凝土工程中用減水劑和緩凝劑。其減水、增塑、緩凝作用都很顯著，能夠大大前進混凝土的和易性，減少坍落度丟失，前進混凝土的后期強度，作為緩凝劑可使初凝時間從幾小時延伸到幾天而無損強度。并且適用范圍廣，泵送混凝土、大流動性混凝土、大體積混凝土、高強度功能混凝土中均可使用。
葡萄糖粉能夠作水泥摻合劑：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%的葡萄糖酸鈉，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。Industrial glucose is used as water reducer and retarder in concrete engineering. Its water reducing, plasticizing and retarding effects are remarkable. It can greatly advance the workability of concrete, reduce the loss of slump and the late strength of forward concrete. As a retarder, the initial setting time can be extended from several hours to several 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?？伤苄耘c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.
