要求用高含量。特别是造纸,化妆品制作中更是要用高含量的。
处理饮用水必须用饮水级的,工业级的在检测时不方法所得出的分类是不一样的,假如依照离子型可分为阴、非、两性及阳离子聚丙烯酰胺,假如依照形状的话,能够分为胶体、涣散液、乳液和干粉颗粒四种形状,那么这四种形状哪一种更适合我们呢?公司给您一些主张,接下来是我们的经历所得,希望您会感兴趣。延缓凝固,使空气成气泡状存在,减少用水量和增加 塑性等等。通常在水泥中同时使用数种掺合剂,各种不同的掺合剂在一些应用中能互相强化。
葡萄糖酸钠可以作为掺合剂用在混凝土中,它在混凝土中的功能如下: 减水剂和缓凝剂葡萄糖酸钠一般是单独使用,但是也可以与其它缓凝剂如碳水化合物和磷酸盐配合起来使用。葡萄糖酸钠是一种结晶的粉末。是在妥善规定和控制的条件下生产出来的。此化合物是化学纯的并且无腐蚀性。质量是恒定的。这些特点能保证它在应用中有可靠的和重复性的结
溶解性:极易溶于水,略溶于酒精,不能够溶于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
??在平常假如我们常常运用,能够选择干粉颗粒状聚丙烯酰胺,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,一般情况下干粉聚丙烯酰胺在干燥、阴凉的当地是寄存二年以上的,但假如配成溶液的话,它的寄存时刻就有限了,一般说,溶液浓度为0.1%的时候,非离子与阴离子聚丙烯酰胺溶液不会超过一周的时刻,阳离子聚丙烯酰胺溶液则不会超过一天,而且溶液的稳定性与溶液的浓度有关,配的浓度越浓,例如3%——5%的溶液寄存时刻越长,但3%——5%的溶液不能直接去处理污水,这种在运用前需要稀释,阳离子聚丙烯酰胺溶液PH值小于5.5的时后比较稳定,假如大于6.0的话,就会由于水解的原因而失效,水介质涣散型聚丙烯酰胺保质期为六个月。
??所以聚丙烯酰胺仍是选用固体的比较好,能够做到随配随用,不造成糟蹋。
??当然大家一定要注意保存聚丙烯酰胺各种条件和忌讳,聚丙烯酰胺对铁离子、钙离子、镁离子比阴离子聚合物质灵敏,尤其是铁离子是造成所有聚丙烯酰胺化学降解的催化剂,所以在制造、搬运与储存聚丙烯酰胺溶液的话,一定要尽量避免铁离子进入与溶液触摸设备要用塑料、不锈钢、玻璃钢或表面涂料树脂的碳钢制造。
检工业葡萄糖在混凝土工程中用减水剂和缓凝剂。其减水、增塑、缓凝作用都很显着,能够大大前进混凝土的和易性,减少坍落度丢失,前进混凝土的后期强度,作为缓凝剂可使初凝时间从几小时延伸到几天而无损强度。并且适用范围广,泵送混凝土、大流动性混凝土、大体积混凝土、高强度功能混凝土中均可使用。
葡萄糖粉能够作水泥掺合剂:水泥中添加必定数量葡萄糖粉后,可添
加混凝土的可塑性和强度,且有阻滞作用,即推迟混凝土的开始与终究凝聚时期,例如添加0.15%的葡萄糖酸钠,可将混凝土的初凝聚时间延伸10倍以上,也就是将混凝土的可塑时间从几小时延伸至几天,而不影响其牢度。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.
水泥中添加必定数量葡萄糖粉后,可添加混凝土的可塑性和强度,且有阻滞作用,即推迟混凝土的开始与终究凝聚时期,例如添加0.15%的葡萄糖粉,可将混凝土的初凝聚时间延伸10倍以上,也就是将混凝土的可塑时间从几小时延伸至几天,而不影响其牢度。可塑性与推迟开始凝聚时间在混凝土作业中是非常重要的问题,如在高温度季节施工及大型的工程作业中,推迟开始凝聚时间则是个难题,葡萄糖粉可圆满解决这个问题。别的高温时胶接油井是比较困难的,添加了葡萄糖粉后的混凝土在170℃高温下,在几个小时内可塑,因此也能圆满解决上述问题。因此葡萄糖粉作为水泥掺合剂在国外已许多使用于重要的建筑工程,如中东的许多桥梁工程中。但是我们国内在这方面使用也还未太广泛,据说有在造纸废水中提炼纤维素磺酸钠,其作用与葡萄糖粉根本是不可相提并论的。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.
测重金属,另外水不溶物也高于饮用水的,总的来说饮用水级的关乎人命,不能乱用,一定要是真正的饮用水级的,如果工业级的被用于饮用水,隐患很多。而且纯度不同,工业用都是26-28%,饮用水用30%。
而污水处理的话,含量高低要求并不严格,含量低的不是太多就行,可以多投放些药剂也可以达到预定的效果。
