When we buy a disinfection cabinet, we often encounter the disinfection level label, but what is the disinfection level? What are the specific meanings, is it a good level or a second level? These problems have troubled many people who have just contacted the disinfection cabinet. Consumer. Let me introduce you to this knowledge.
The General Administration of Quality Supervision, Inspection and Quarantine and the China National Standardization Committee revised the 2004 edition of the “Safety and Hygiene Requirements for Disinfection Cabinetsâ€. On December 31, 2008, the new national standard “gb17988—2008†was released. Safety and Health Requirements, implemented on February 1, 2010. The standard specifies the definition, scope, classification, number of stages, markings and instructions, physical and chemical properties, effect testing, safety and technical specifications of the disinfection cabinet. According to reports, disinfection cabinet disinfection star standard provisions: disinfection cabinet (room) disinfection effect is divided into two levels, one star and two stars.
One-star disinfection standard: It can kill representative strains such as E. coli. When ozone is disinfected, the concentration of ozone in the disinfection cabinet should be greater than or equal to 20 mg per cubic meter, and the disinfection time should be greater than or equal to 30 minutes. When disinfecting at high temperature, the disinfection temperature in the disinfection cabinet should be greater than or equal to 100 degrees Celsius, and the disinfection time should be greater than or equal to 15 minutes.
Two-star disinfection standard: In addition to the elimination of E. coli, the disinfectant also has representative strains such as "poliovirus". When ozone is disinfected, the concentration of ozone in the disinfection cabinet should be greater than or equal to 40 mg per cubic meter, and the disinfection time should be 60 minutes or more. When disinfecting at high temperature, the disinfection temperature in the disinfection cabinet should be greater than or equal to 120 degrees Celsius, and the disinfection time should be greater than or equal to 15 minutes.
The new national standard clearly states in the “Marking and Description†section that the front position of the disinfection cabinet should be marked with the disinfection level of the disinfection cabinet to indicate different disinfection effects. The disinfection cabinet should have at least one chamber with a disinfection effect of the order of magnitude. The one-star disinfection cabinet (room) is marked with the disinfection star "*"; the two-star disinfection cabinet (room) is marked with the disinfection star "**". Do not use the "disinfection star" mark in the disinfection room that does not reach the disinfection level of the disinfection cabinet, and indicate the use function of the room.

Product Introduction
Nonionic polyacrylamide PAM Flocculant is a type of Water Treatment Chemical with soluble high molecular weight polymer or polyelectrolyte. It is white powder or granule with the solid content ≥90% and molecular weight of 2-22 million. It is non-toxic, and can be dissolved in the water easily but not the organic solvents. PAM Polyacrylamide Flocculant, DBNPA 2,2 Dibromo 3 Nitrilopropionamide , TTA Tolyltriazole , Polyaluminum Chloride PAC and Isothiazolinones Bactericide are all Water Treatment Material .
Product Advantage
1). Flocculation ability, high adsorption activity, floc formation and deposition quickly.
2).Without alkali and other additives, PH broad in scope, ease of use; for low-temperature, low turbidity, low alkalinity of the raw water is also good flocculation.
3).Easy to use and high effective.
