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.

Desc：In recent days, everyone has been discussing the rapid change of weather and temperature in the north, and the weather map shows that it is frozen black. In winter, how to clear the ice and snow on the road in time and ensure the smooth traffic has become a major problem for the northern cities. What Xiaobian wants to tell you today is that snow melting agent is commonly used in winter snow removal, because snow melting is convenient and fast, which ensures smooth road and driving safety after snow. But snow melting agent also needs to use environmental protection type. Potassium formate can not only prevent the road from freezing, but also does not pollute the groundwater resources, causing environmental damage.
