Desc：In recent years, food safety has become an increasingly important topic for eating. Food additives, as a non-negligible part of them, have also attracted more and more attention. Because of the illegal use of food additives, people have a certain misunderstanding. Today, let’s learn a few things you don’t know about food grade sodium hexametaphosphate.

Desc：Water treatment agent is necessary for the disposal of industrial water, domestic water and waste water. Sodium hexametaphosphate is a very widely used fine phosphate product. From the initial red treatment of water, with the development of industry, the application of sodium hexametaphosphate industrial grade is more widely.

Desc：With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use. Calcium formate industrial grade is a good early strength agent.

Desc：Drilling is one of the more technical tasks. The choice of drilling fluid should be adapted to local conditions according to various links. It is not that the more money you spend, the better the effect. According to the geothermal survey results, the local geological hydrothermal conditions are obtained, the geothermal drilling design process and construction plan are determined, and the corresponding drilling rig and other corresponding materials are selected. The manufacturer of potassium formate will tell you why use potassium formate drilling fluid for drilling construction.

Desc：The pretreatment of pure cotton or polyester-cotton fabric is mainly to remove impurities on the cotton fiber, so that the fabric has good printing and dyeing processing performance. The conventional desizing, scouring and bleaching processes are set up for different impurities. Which of the commonly used additives in printing and dyeing, sodium hexametaphosphate or soda ash, has a better softening effect?

Desc：In the eyes of laymen, oil extraction is similar to water wells. In fact, oil extraction needs to go through a series of processes such as exploration, determining the position, number and depth of wells. In the drilling process, technical equipment (including drilling rigs, derricks) and a set of lifting system and drill rods, drilling tools and drill bits are also required. Drilling fluid is related to the environment, reservoir and petroleum quality. Oil extraction is not easy. How to use potassium formate to "extract" oil from deep wells?
