Why is the unit price of food additive sodium tripolyphosphate higher than that of industrial grade? The manufacturer tells you

  Recently, the shortage of spot goods has intensified, which has entangled downstream manufacturers who want to purchase recently. Either they have not found a suitable manufacturer, or the price is not too expensive. Sodium tripolyphosphate, as a basic chemical material and related phosphorus containing products, plays an important role, and the relative price has also increased. Why is the unit price of   food additive sodium tripolyphosphate  higher than that of industrial grade? The manufacturer tells you. First of all, it can be seen literally that the content and related indicators of industrial grade sodium tripolyphosphate meet the national standard. The main raw material of sodium tripolyphosphate is phosphate rock. In the production process, the price of wet process is slightly lower, while the sodium tripolyphosphate produced by thermal process is relatively higher. The raw material of food additive sodium tripolyphosphate is based on the thermal process. As a...

Sodium cyanate for metal heat treatment increases wear resistance and corrosion resistance

For large castings, in the actual production, the deformation caused by heat treatment is very important to the subsequent process, and there are a lot of scrap due to excessive deformation. In order to reduce and control the deformation of large castings caused by heat treatment, we can optimize the process parameters of heat treatment, increase the isothermal stage, control the heating rate and the temperature of parts, and increase the quenching water temperature. Many manufacturers will buy  sodium cyanate  as heat treatment agent to reduce the deformation of heat treatment. In the process of heating and warming up, the surface temperature of the parts rises rapidly, the center temperature rises slowly, and there is thermal stress when there is a temperature difference between the surface and the center. The faster the heating speed, the greater the wall thickness of the parts, the greater the temperature difference and the greater the thermal stress produced. In the proce...

Let's see how to purchase food additive sodium hexametaphosphate/SHMP

The food additive industry is related to people's livelihood. It can be imagined how complex the difficulties of food safety management are, and food safety problems, such as excessive use of additives, are prone to occur with little attention. How to purchase  food additive sodium hexametaphosphate/SHMP ? First of all, no matter where you are, you must confirm whether the manufacturer of food grade sodium hexametaphosphate has the relevant qualifications. Food grade sodium hexametaphosphate/SHMP manufacturer: Chongqing Chuandong Chemical Group, as the manufacturer, has the qualification for food additive production. On the premise of being able to provide sufficient sources of goods, it is more able to accept unannounced inspections by various food companies. After understanding the qualifications of food grade manufacturers, you must clarify your purchasing needs, each item is particularly important, and each demand point. 1. The quality standard of food grade sodium hexametaphos...
