5-30 parts of silver-ion antibiotic powder, 0-20 parts of nanometer anion powder, 20-50 parts of nanometer infrared ray powder；
Wherein, antibacterial and mouldproof mechanism mainly has following aspects:
Nano zine oxide sterilization mechanism:
1. Electrostatic Absorption, due to the combination of zinc and oxygen, the electronegativity of zinc oxide surface is big compared with general metal ion, electronegativity
It is mainly derived from nanoscale and structure, due to its nanoscale, more zinc atoms are exposed in appearance, so that its more surface band
Positive electricity；If nano zine oxide crystal form is imperfect, surface defect is more, also will increase electropositive.And cell wall (the peptide of cell surface
Glycan, teichoic acid, lipopolysaccharides), cell membrane (phosphatide) all to be negatively charged, according to charge there is a natural attraction between the sexes principle, bacterium can be without selection
Absorption.
2. Ion release destroys bacterial cell cell wall, zinc ion is released from its zinc oxide surface and cell, replaces it
Originally the Ca of its physiological activity was adjusted, Mg plasma, so that albuminous degeneration solidification, enzyme lose activity, so that cell wall, thin
The original disabler of after birth.
3. photo-catalyst, the water inside and outside Nanometer Zinc Oxide Catalyst bacterial body generates H2O2: Nanometer Zinc Oxide Catalyst bacterium
Body surface water generates H2O2, the strong oxidizing property and its oxidisability product of H2O2 can direct oxidation bacterium layer structure, make cell-permeant
Property barrier destroyed, inside and outside bacterial body material balance by destroy cause bacterial death.The decomposition product of H2O2 such as hydroxyl and work
Property the free group such as oxygen can directly react with microprotein and nucleic acid, make the structure of matter cause it dead by destruction
It dies.
Nano zine oxide can destroy bacterium, virus in cell membrane, make bacterium mass flow lose, solidification virus protein, In
While exterminating bacterium, moreover it is possible to decompose the harmful compound discharged in bacterium residuum, therefore, nano zine oxide to bacterium, mould,
Virus has very strong killing effect, and nano zine oxide also has deodorization.Research has shown that nano zine oxide is to thin
Bacterium, virus bactericidal rate can reach 99% or more, deodorizing rate is up to 99% or more.

Infrared frequency is lower, and energy is inadequate, atom is much not achieved, the effect that molecule disintegrates.Therefore, infrared ray can only penetrate
In the gap of atom or molecule, and the inside of atom, molecule cannot be penetrated into, due to infrared ray can only be penetrated into atom, point
The gap of son, can be such that atom, the vibration quickening of molecule, spacing widens, i.e., increase zinc ion, silver ion and anion diffusion and
Permeability improves antibacterial and mouldproof performance Unwinding to booster action.
