葡萄糖酸鈉是一種有機(jī)物，在工業(yè)和食品行業(yè)用途均十分廣泛，下面氫氧化鉀廠家就來為您講講葡萄糖酸鈉在混凝土應(yīng)用中如何。

Sodium gluconate is an organic substance, which is widely used in industry and food industry. The following potassium hydroxide manufacturers will tell you about the application of sodium gluconate in concrete.

葡萄糖酸鈉在混凝土應(yīng)用中，可以延長(zhǎng)混凝土凝結(jié)時(shí)間、降低混凝土的坍落度及其經(jīng)時(shí)損失、提高混凝土的強(qiáng)度。在泵送混凝土、大流動(dòng)性混凝土、大體積混凝土、高強(qiáng)度性能混凝土中均可應(yīng)用。具體應(yīng)用如下：

In the application of concrete, sodium gluconate can prolong the setting time of concrete, reduce the slump and its loss over time, and improve the strength of concrete. It can be used in pumping concrete, high fluidity concrete, mass concrete and high strength performance concrete. Specific applications are as follows:

（1）使用葡萄糖酸鈉可以降低水灰比，從而提高混凝土強(qiáng)度。這是一種好的混凝土。

(1) The use of sodium gluconate can reduce the water cement ratio and improve the strength of concrete. This is a good concrete.

（2）大塊和大重量的灌注工程是較難施工的。由于加了葡萄糖酸鈉，混凝土工作性的改善和凝固時(shí)間的延緩能夠避免結(jié)構(gòu)上產(chǎn)生相接面，其結(jié)果能增進(jìn)結(jié)構(gòu)強(qiáng)度。

(2) It is difficult to construct large and heavy grouting projects. Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of setting time can avoid the occurrence of interface on the structure, which can improve the structural strength.

（3）保持水灰比不變，提高高溫地區(qū)的可加工性具有重要意義。在中東的橋梁建設(shè)中，使用了大量的葡萄糖酸鈉。

(3) It is of great significance to keep the water cement ratio unchanged and improve the processability in high temperature areas. A large amount of sodium gluconate is used in bridge construction in the Middle East.

（4）在混凝土拌合料中加入葡萄糖酸鈉，能延緩凝固時(shí)間，這對(duì)長(zhǎng)時(shí)間和高難度的灌注很重要。

(4) Adding sodium gluconate to the concrete mixture can delay the setting time, which is important for long-term and difficult pouring.

（5）在現(xiàn)代混凝土工業(yè)中，預(yù)拌混凝土在中心位置制備，然后由攪拌車運(yùn)輸出去。在這種情況下，增加和易性和初凝時(shí)間非常重要。

(5) In the modern concrete industry, ready mixed concrete is prepared in the center and then transported out by the mixer truck. In this case, it is very important to increase workability and initial setting time.

（6）降低w/c比能制成更高強(qiáng)度和耐久性的混凝土，葡萄糖酸鈉能達(dá)到此目的。這對(duì)高強(qiáng)度的鋼筋混凝土甚為重要。

(6) Reducing w / C ratio can make concrete with higher strength and durability, and sodium gluconate can achieve this purpose. This is very important for high strength reinforced concrete.

（7）砌筑用預(yù)制砂漿必須長(zhǎng)期使用。添加葡萄糖酸鈉可以延長(zhǎng)工作時(shí)間。

(7) Precast mortar for masonry must be used for a long time. Adding sodium gluconate can prolong the working time.

（8）油井灌溉泥漿溫度高，操作難度大。加入葡萄糖酸鈉后，混凝土可在170℃下工作數(shù)小時(shí)。

(8) The temperature of the oil well irrigation mud is high and the operation is difficult. After adding sodium gluconate, the concrete can work at 170 ℃ for several hours.

此外該產(chǎn)品還主要用作食品添加劑，在建筑、紡織印染和金屬表面處理以及水處理等行業(yè)作螯合劑，鋼鐵表面清洗劑，玻瓶清洗劑，電鍍工業(yè)鋁氧著色等。更多相關(guān)事項(xiàng)就來我們網(wǎng)站http://www.shrisa.cn咨詢了解吧。
