Description

Accurate quantitative adding equipment for preservative Technical Field The invention relates to the technical field of preservative adding, in particular to precise quantitative preservative adding equipment. Background The preservative is adopted in the production of the detergent to avoid the deterioration of the product due to bacterial pollution, so that the quality of the detergent product can be improved, the cost is reduced, and the shelf life of the product is greatly prolonged. The Kathon preservative is used as a powerful, broad-spectrum, efficient and nontoxic green auxiliary agent product, and has been widely used in the aspects of tableware detergents, liquid detergents and the like. The main components of the preservative are mainly composed of 5-chloro-2-methyl-4-isothiazolin-3-one (CIT) and 2-methyl-4-isothiazolin-3-one (MIT). Isothiazolinones act biocidal by breaking the bonds of bacterial and algal proteins. After the isothiazolinone is contacted with microorganism, the growth of the isothiazolinone can be quickly and irreversibly inhibited, so that the death of microorganism cells is caused, and the isothiazolinone has strong inhibition and killing effects on common bacteria, fungi, algae and the like, and has the characteristics of high biocidal efficiency, good degradability, no residue, good compatibility, strong stability, low use cost and the like. Is miscible with chlorine and most anionic, cationic and nonionic surfactants. Effectively prolongs the storage time of the detergent and reduces the safety risk caused by deterioration. The inventor considers that the prior related technology has the defects that the preservative is generally added into the batching pot after being manually weighed at present, the batching pot is not sealed any more after being manually added, other pollution sources are easily brought into contact with air to influence the quality of products, splashing liquid is easily generated in the preservative weighing process, high-concentration methylisothiazolinone has strong anaphylaxis, contact dermatitis is possibly caused by direct contact with the high-concentration methylisothiazolinone, and the symptoms such as redness, itching, peeling and the like are expressed, so that the direct contact is avoided in the production process. The raw materials are strong in acidity and have certain corrosiveness to common metal materials, and meanwhile, in order to avoid the defect that the addition of the methyl isothiazolinone preservative in the detergent is insufficient, the sterilization effect is weakened or the addition is too high, so that a certain risk is brought.
