Application and types of preservatives
Application and types of preservatives:
Bacteria are everywhere, such as dust, soil, sweat, air. As long as it meets the right temperature and humidity, it begins to grow and multiply from uneven places. Therefore, the first place to grow mold is generally at the interface, where stitches are made, which is a great harm to the storage and transportation of raw materials and their products. The main function of preservatives is to no longer grow mildew even in the harsh humid environment. Preservatives series of mildew prevention principle: destroy the bacterial cell wall and the enzymes in the cell, so that the enzyme proteins can not participate in the catalytic action, effectively prevent the growth and reproduction of bacteria, preservatives mainly include the following:
(1) Bamboo and wood preservatives: the main component is organic silicone quaternary ammonium salt. Bamboo and wood preservatives, as the name suggests, protect wood from mildew during production, storage and transportation, and avoid deterioration or discoloration caused by bacteria, bacteria, algae and yeast; Keeps items such as furniture fresh because it inhibits or prevents the growth of odor-causing bacteria and bacteria; Can extend the service life of items, because it inhibits the growth of bacteria and bacteria; Can make articles clean and sanitary, insect prevention; The result of treatment is very good, and it can be cleaned and washed repeatedly. Due to other chemical protection properties, can prevent odor; Has a good compatibility with substrates and processes within the licensed uses.
(2) textile mildew antifungal agent: also known as mildew antifungal agent. It is a milky white liquid with good stability, moisture absorption and perspiration. Textile antibacterial agent is successfully developed by Aegis Microbe Shield, a chemical technology company, which can effectively inhibit Gramella, Staphylococcus aureus, Escherichia coli, pyobacterium pneumoniae, yeast, fungi, insect mites and algae, etc. Textile antibacterial agent will give the treated substrate superior durability, and has a unique protection against microbial antibacterial function. It can be used for both dyeing engineering and finishing process of fiber fabrics before treatment, so as to prevent the harm caused by microorganisms and prolong the use time of fabric.
(3) Leather preservatives: This is a commonly used leather preservative, but also a kind of anti-aging agent, very low toxicity, this product is colorless liquid, slightly irritating flavor, and a variety of leather has a good match performance and good anti-mildew effect, long leather protection cycle, the price is very reasonable, leather in the production and storage process is vulnerable to microbial attack and corruption and mildew, In view of the special process conditions of high salt, high acid and alkali in the leather process, a series of sterilization and mildew preservatives have been developed, which have broad spectrum and do not contain phenols and solvents harmful to the environment, and meet the strict requirements of import and export quarantine and inspection in Europe and America. The characteristics of leather preservatives can be widely used in various production modes. If batch type and continuous type can be processed as far as possible without changing the conditions of the process and production equipment, they belong to the non-release type of treatment agent, do not lose, do not move, nor be consumed by microorganisms, can give the substrate surface superior durability, with special mechanical sterilization, no drug resistance phenomenon, they can effectively inhibit the growth of bacteria. Prolong the probation period and storage period of leather, and no harm to the user's health.
