As we all know, caustic soda is a basic chemical raw material, which is widely used, such as paper, synthetic laundry soap, viscose fiber, rayon and cotton fabric, etc. How to dissolve caustic soda in use?

產生的堿性片堿片制造商基本上是白色半透明片狀固體,但也會有如此的片堿生產過程污染或堿溶液和設備有一個輕微的反應會產生一些紅色,藍綠色或灰色混合顏色。所以選購時一定要選擇顏色純正的白色，板材厚度薄，面積小的板堿。這種藥片使用時更容易溶解。

The alkaline flake alkali produced by the manufacturer is basically a white translucent flake solid, but there will also be such flake alkali production process pollution or a slight reaction between the alkali solution and the equipment will produce some red, blue-green or gray mixed colors. Therefore, we must choose pure white color, thin plate thickness, small area of plate alkali. The tablets are easier to dissolve when used.

溶解時，攪拌并同時焯水。在水中放置太久或一次全部倒入水中會導致結塊和緩慢的溶解。溶解沒有冷卻,待完成后一個溶解再酷所以我們可以得到更高的堿濃度,此外,高堿溶解度較高的溫度場,堿液濃度較高,但小心不要把太多的堿,因為一旦飽和溶液的溶解度,然后把一塊堿不會溶解,將凝聚的效果。

When dissolved, stir and blanch. Placing in water too long or pouring it all in at one time can cause caking and slow dissolution. The dissolution is not cooled. After the completion of a dissolution, we can get a higher alkali concentration. In addition, the temperature field with a higher alkali solubility has a higher alkali concentration, but be careful not to put too much alkali, because once the solubility of the saturated solution is reached, then a piece of alkali will not be dissolved, and the effect of agglomeration will be achieved.

腐蝕性極強的鱗片，其溶液或粉塵濺在皮膚上，特別是濺在粘膜上，可產生軟痂，并可穿透深層組織。燒傷留下了疤痕。濺入眼睛，不僅會損傷角膜，還會使眼睛深層組織受損。如不慎濺到皮膚上，應立即用清水沖洗10min;如有濺出，應立即用清水或生理鹽水沖洗15分鐘，然后加入2%的奴佛卡因。嚴重的病例很快被送往醫院。空氣中燒堿粉塵的允許濃度為0.5mg/m3。操作人員必須穿戴工作服、面罩、防護眼鏡、橡膠手套、橡膠圍裙、膠靴等勞動防護用品。在皮膚上涂上一種中性的疏水性軟膏。車間應該通風良好。

The scales with strong corrosiveness can produce soft scabs and penetrate deep tissues when the solution or dust is splashed on the skin, especially on the mucous membrane. The burn left a scar. Splashing into the eyes will not only damage the cornea, but also damage the deep tissues of the eyes. In case of splashing on the skin, wash it with clear water for 10min immediately; in case of splashing, wash it with clear water or normal saline for 15min immediately, and then add 2% novocaine. Serious cases were quickly taken to hospital. The maximum allowable concentration of caustic soda dust in the air is 0.5mg/m3. Operators must wear work clothes, masks, protective glasses, rubber gloves, rubber apron, rubber boots and other labor protection articles. Apply a neutral hydrophobic ointment to the skin. The workshop should be well ventilated.
