1. As a common chemical substance in the biological and its petrochemical industries, flake soda needs to go through several processes in the production process. In the process of decorative works, each process has a different effect. The purpose of the fractionation process is to facilitate the removal of some residues. Multiple fractional distillation of the liquid flowing through the pipe is not allowed to use, because the residue in the pipe will damage its purity.
　　2, the flake soda in the fractionation process to strictly control the fractionation temperature, but also to control the amount of steam added.
　　3, If there is too much steam and the temperature is too high, the high melting point organic matter will be taken out from the top of the tower, resulting in an impure product.
　　4, in the process of fractional distillation, to prevent the distillation kettle to produce rushing kettle, but also to maintain the stability of the use.
　　5, the amount of steam in the operation is too small, the temperature is a little low, flake soda fractionation is slow will jeopardize the progress, so you need to control the amount of steam. Temperature is the key parameter of product fractionation, which will jeopardize the quality of goods. This stipulates that manufacturers should constantly improve the traditional production process, control the temperature, and reduce the failure rate of the commodity.
