要求用高含量。特別是造紙,化妝品制作中更是要用高含量的。
處理飲用水必須用飲水級的,工業(yè)級的在檢測時(shí)不方法所得出的分類是不一樣的,假如依照離子型可分為陰、非、兩性及陽離子聚丙烯酰胺,假如依照形狀的話,能夠分為膠體、渙散液、乳液和干粉顆粒四種形狀,那么這四種形狀哪一種更適合我們呢?公司給您一些主張,接下來是我們的經(jīng)歷所得,希望您會感興趣。延緩凝固,使空氣成氣泡狀存在,減少用水量和增加 塑性等等。通常在水泥中同時(shí)使用數(shù)種摻合劑,各種不同的摻合劑在一些應(yīng)用中能互相強(qiáng)化。
葡萄糖酸鈉可以作為摻合劑用在混凝土中,它在混凝土中的功能如下: 減水劑和緩凝劑葡萄糖酸鈉一般是單獨(dú)使用,但是也可以與其它緩凝劑如碳水化合物和磷酸鹽配合起來使用。葡萄糖酸鈉是一種結(jié)晶的粉末。是在妥善規(guī)定和控制的條件下生產(chǎn)出來的。此化合物是化學(xué)純的并且無腐蝕性。質(zhì)量是恒定的。這些特點(diǎn)能保證它在應(yīng)用中有可靠的和重復(fù)性的結(jié)
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(yùn)用,能夠選擇干粉顆粒狀聚丙烯酰胺,The classification obtained by the b 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 bs 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(dāng)?shù)厥羌拇娑暌陨系?,但假如配成溶液的話,它的寄存時(shí)刻就有限了,一般說,溶液濃度為0.1%的時(shí)候,非離子與陰離子聚丙烯酰胺溶液不會超過一周的時(shí)刻,陽離子聚丙烯酰胺溶液則不會超過一天,而且溶液的穩(wěn)定性與溶液的濃度有關(guān),配的濃度越濃,例如3%——5%的溶液寄存時(shí)刻越長,但3%——5%的溶液不能直接去處理污水,這種在運(yùn)用前需要稀釋,陽離子聚丙烯酰胺溶液PH值小于5.5的時(shí)后比較穩(wěn)定,假如大于6.0的話,就會由于水解的原因而失效,水介質(zhì)渙散型聚丙烯酰胺保質(zhì)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(dāng)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(zhì)靈敏,尤其是鐵離子是造成所有聚丙烯酰胺化學(xué)降解的催化劑,所以在制造、搬運(yùn)與儲存聚丙烯酰胺溶液的話,一定要盡量避免鐵離子進(jìn)入與溶液觸摸設(shè)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(yè)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(jìn)混凝土的和易性,減少坍落度丟失,前進(jìn)混凝土的后期強(qiáng)度,作為緩凝劑可使初凝時(shí)間從幾小時(shí)延伸到幾天而無損強(qiáng)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(qiáng)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(shù)量葡萄糖粉后,可添
加混凝土的可塑性和強(qiáng)度,且有阻滯作用,即推遲混凝土的開始與終究凝聚時(shí)期,例如添加0.15%的葡萄糖酸鈉,可將混凝土的初凝聚時(shí)間延伸10倍以上,也就是將混凝土的可塑時(shí)間從幾小時(shí)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(shù)量葡萄糖粉后,可添加混凝土的可塑性和強(qiáng)度,且有阻滯作用,即推遲混凝土的開始與終究凝聚時(shí)期,例如添加0.15%的葡萄糖粉,可將混凝土的初凝聚時(shí)間延伸10倍以上,也就是將混凝土的可塑時(shí)間從幾小時(shí)延伸至幾天,而不影響其牢度。可塑性與推遲開始凝聚時(shí)間在混凝土作業(yè)中是非常重要的問題,如在高溫度季節(jié)施工及大型的工程作業(yè)中,推遲開始凝聚時(shí)間則是個難題,葡萄糖粉可圓滿解決這個問題。別的高溫時(shí)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(shí)內(nèi)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(nèi)在這方面使用也還未太廣泛,據(jù)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.
測重金屬,另外水不溶物也高于飲用水的,總的來說飲用水級的關(guān)乎人命,不能亂用,一定要是真正的飲用水級的,如果工業(yè)級的被用于飲用水,隱患很多。而且純度不同,工業(yè)用都是26-28%,飲用水用30%。
而污水處理的話,含量高低要求并不嚴(yán)格,含量低的不是太多就行,可以多投放些藥劑也可以達(dá)到預(yù)定的效果。
