Desc：Recently, due to the decrease of temperature, the use of cement mortar early strength agent has increased. Chongqing Chuandong Chemical has also received many inquiries about how to identify the true and false calcium formate and its purity, which is a simple and quick method. Calcium formate is very likely to be adulterated with sodium formate powder. Both calcium formate and sodium formate powder can play an important role in anti freezing and early strengthening in construction. However, the amount of calcium formate added in mortar is far less than that of sodium formate powder, but the effect is stronger than that of sodium formate powder, and the price of sodium formate powder is far lower than that of calcium formate. In order to avoid the loss of use caused by the user buying adulterated calcium formate, we share it with you today. The difference and distinguishing method of powder.

Desc：In order to protect the modern environment, it is necessary to prevent well collapse, well loss and protect the oil and gas reservoir. For the formation with developed bedding and fracture, in order to prevent well collapse and leakage and reduce the damage to oil and gas reservoir, the drilling fluid is required to have strong sealing property, effectively seal the bedding and fracture of the formation, prevent the drilling fluid and its filtrate from entering the formation, so as to improve the pressure bearing capacity of the formation, stabilize the well wall, prevent well leakage and protect the oil and gas reservoir. We will talk about the detailed values of potassium formate and sodium formate in weighting agent of drilling and completion fluid.

Desc：Chongqing Chuandong chemical will talk about the use of sodium hexametaphosphate in textile printing and dyeing today, because it is really easy to use. With good auxiliaries in textile printing and dyeing, the textile can be upgraded to a higher level. Today, let's count the uses of sodium hexametaphosphate in textile printing and dyeing.

Desc：With the increasing consumption power of people, food is becoming more and more colorful. Food moisture retention agent plays an important role in food industry. Sodium tripolyphosphate is one of the food water retention agents.

Desc：The quality of water not only has a great influence on the product quality of pretreatment and other processes, but also affects the consumption of dyeing and chemical materials and auxiliaries. In textile printing and dyeing industry, sodium hexametaphosphate is a good softener, which makes the dye or soap powder not precipitate or agglomerate.

Desc：Water retention agent refers to a kind of substance which can improve the stability of products, keep the internal water retention of food water retention agent and improve the shape, flavor and color of food. Food grade sodium tripolyphosphate helps to maintain the water content in food. It is mainly used in meat and aquatic products processing to enhance the water stability and high water holding capacity.
