2021-10-14   Pageview:365

455 belongs to the special mold inhibitor for foamed plastics, with the appearance of colorless and transparent liquid, its temperature resistance can reach more than 250℃. This product has a broad-spectrum antibacterial effect, and has a significant inhibitory effect on common mold, yeast, algae, and has been widely used in shoe insoles, rubber sticks, construction sealant, silicone adhesive, PVC, EVA, TVA, EPP, PP, PE, PET, SBR, CR, ABS and coatings and other materials.

 

 

 

 

 

 

 

 

 

 

 

 

Advantages: Fast and broad-spectrum sterilization, high efficiency, especially with gas-phase sterilization ability, so that the upper space of the container is protected, which is needed for large-scale production wax additives for epoxy resin of storage tank storage and pipeline transportation, and the price is moderate.
Disadvantages Formaldehyde is suspected to be the third type of carcinogen, with poor thermal stability, lower efficiency when pH<6, volatilization and strong odor.

Formaldehyde is toxic to humans and is generally considered to be irritant, allergic and carcinogenic. Some countries stipulate the allowable concentration of formaldehyde gas in indoor air (mg/m*): 0.24 in the United States (Wisconsin) and Switzerland, 0.12 in Japan and Germany, and 0.08 in my country [9]. 6. Examples of products
The formaldehyde-releasing preservatives are: N-formal (N-formal) and O-formal (O-formal). O formal releases formaldehyde faster than N-formal. Commodities also include Troy san 174, Troy san 186, Nuo sept 95, Eco cide BA and so on.

5-chloro-2-methyl-4-isothiazolin-3-one/2-methyl-4-isothiazolin-3-one ten formaldehyde-releasing preservative
In the coatings industry, different anti-corrosion components can be combined and compounded in different proportions in order to complement each other’s advantages and achieve the desired results of expanding the antibacterial spectrum, reducing the dosage, reducing costs and improving environmental friendliness, which is called synergy [10 ], 5-chloro-2-methyl-4-isothiazolin-3-one/2-methyl-4-isothiazolin-3-one + formaldehyde-releasing preservative (CM IT/MIT+FR), It is a very common combination and compounding method, which has a synergistic effect, not only has the protective effect of the upper space of the container, but also has a high-efficiency and broad-spectrum bactericidal effect. Moreover, the release of formaldehyde-type preservatives will improve the stability of CM IT, but the formaldehyde content should not exceed the standard. Of course, not all compounds have synergistic effects.

The preservatives belonging to this category include Act icid eHF, Parme to IA 26, Roe imaGT, Roc ima 623, B actra chemIC, B actra chemIC/2, B actra chemWS 22, Bact rache mWS 44 and so on.
