Biocera A (Nano Silver Inorganic Antibacterial Agent)

Model Number

Powder

Product Introduction

Bio Cera A is nontoxic agent, which is composed of ca-phosphate, Alumina and silica as carrier and Silver Ag ions, which are harmless to the human body. Bio Cera A is an inorganic antibiotic agent and active function to the living body by the infrared rays radiation ceramic at the same time.

Bio Cera A is added to the product, which is endowed with antibiotic function, thus it shows most effective antibiotic ability through contact with various kinds of microbe.

Generally, organic antibiotic agents do not have high heat resistance. In contrast, the inorganic agent Bio Cera A permits better thermal stability even at temperatures up to 1200℃, thus is displaying a wide range of applicability.

Antibacterial mechanism

• Sterilization by active oxygen of ceramic.
• Sterilization by Nano Ag ions.
• Adsorption of bacteria, organic matter and gas.

Features

• FDA certificate (Safety test)
• Antibacterial, antifungal and Deodorizing functions
• Increase electric conductivity
• Prevent aging
• Promote blood circulation
• Decontaminate drinking water
• Non harmful to human body and Non toxic

Application

1. PLASTIC (PE, PP, ABS)

Application and added quality

• Process for application
  Bio Cera A must be used to plastics with powder itself or by the dilution method of concentrated Master Batch (M/B)
• Recommended Grade
  Bio Cera A M/B concentrated 20 ~ 40 wt% by Powder

Key Point

• The antibiotic ability will be depend on the kinds of Resin and property
• The lower density Resin will be better to get the antibiotic effect than the higher density Resin
• The below case shows the best resin on the basis of the same added
  Bio Cera A(powder) Quantity to each Resin PE , PP(2wt%)> PVC, ABS (3 ~4wt%)> PC (Min 4wt%)
• The added quantity will be changed by each company's technology to the degree of  0.2 wt%
• The added quantity of Bio Cera A will be higher than that in case of thermosetting plastic
• It is sufficient that M/B will be concentrated between 20 ~ 40wt%

2. PAINT

Application and added quantity

• Process for application
  Bio Cera A may be used in wet mill processing before the raw material such like resin, solvent, pigment, interfacial active agent are putted in wet mill.
• Recommended grade Bio Cera A powder
• Recommended added quantity min 2 wt%

Key point

• It must be used before wet mill processing
• It will be better for using after make a slice agitation in case of long storage
• If it requires the dilution before using, it would be better to reduce the ratio of dilution

3. COSMETIC

Application and added quantity

• Process for application
  Bio Cera A is mainly used for foundation. color cosmetic itself, cosmetic product case and puff
• Recommended Grade
  Bio Cera A powder
• Recommended added quantity 1.0 wt%

Key point

• It must be used before mixing process
• It is the best way for user only to use inorganic Biocera A itself without any anti-septic agent, but if in case of needed a little antiseptic agent according to cost and other condition, it is available to use both at the same time.

4. CRAYON

Application and added quantity

• Process for application
  Bio Cera A must be putted in mixing process before crayon strength process
• Recommended Grade
  Bio Cera A powder
• Recommended added quantity 1.0 wt%

Key point

• To do raise antibiotic ability at high-dispersion process, it needs to be decided which operation would be reasonable?

5. PAPER

Application and added quantity

• Process for application
  In case of inner paper, The Bio Cera A is used to stencil paper after dispersing uniformly into spread acid. In case of outer paper, The Bio Cera A is used in resin coating process at highly dispersing equally
• Recommended Grade
  Bio Cera A powder
• Recommended added quantity
  1 wt% at stencil paper / 1 wt% at final paper

Key point

• It needs anti-precipitate agent after spread acid mixing at precipitation tank and It needs to maintain high-dispersion
• To get a excellent antibiotic capability, It must be used in mixing together with spread acid and Bio Cera A and effectively wet mill milling.

6. FIBER

Application and added quantity

• Process for application
  It is mixed with A-Type and synthetic resin, then well melting. The fiber will be made after mixing under the condition of high-dispersion.
• Recommended Grade
  Bio Cera A powder
• Recommended added quantity 2.0 wt% at resin

Key point

• It is not available to use in original fiber.
• It is limited to use in double fiber thickness according to A-Type itself tail's size.
• The fiber will be manufactured by mixing with M/B

7. RUBBER

Application and added quantity

• Process for application
  Bio Cera A will be putted before rubber accelerator and other additive had putted in rubber raw material, then fully mixing and subsequent final product strength.
• Recommended Grade
  Bio Cera A powder
• Recommended added quantity 1.0 wt%

Key point

• It must be maintained to put rubber accelerator at first before added Bio Cera A into product under the condition of full rubber process.
