Inorganic Antibacterial Agent

PRODUCT INTRODUCTIONBio Cera A is nontoxic Killing agent, which is composed of ca-phosphate, Alumina and silica as carrier and metal 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 agent does not have high heat resistance. In contrast, the inorganic agent, Bio Cera A permits better thermal stability even at temperature up to 1200°C thus is displaying a wide range of applicability. MECHANISM Sterilization by active oxygen of ceramic. Sterilization by metal ions. Adsorption of bacteria, organic matter and gas. SPECIFICATIONS USAGE ANTIMICROBIAL EFFICACY TESTShake flask Method: cells number/mlTest condition : The solutions are then shaken at 150 times per minute at 25°C for 24hrs, dilutions of cultures are divided by pour agar plate method to determine bacteria cell growth inhibition rate. (Surface area: 60cm2)Test bacteria: Escherichia coli (ATCC 25922) 1)Test Result 2)Percent reduction of bacterial (%)   Rate of Bacteria Reduce 99.9% SAFETY DATAFollow results, Bio Cera A's safety data to the human body.1)Oral toxicity test- Test animal: ICR mouse- Test items: LD50 value > 10,000mg/kg- Clinical symptoms: None- Variation of weight: None 2)Patch Test - Object of test: men - Test result: (-) 3)Mutation test - Object of test: Salmonella Typhimurium - Test result: (-) - So, the Bio Cera A is harmless to the human body. APPLICATION 1. PLASTIC (PE, PP, ABS)1) Application and added quality Process for applicationBio 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 powder, 10wt% M/B Recommended added quantity : 1.0 ~ 2.0 wt% per base resin 2) 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 show you which is the most reasonable resin on the basis of the same added Bio Cera A Quantity to each ResinPE (1wt%) > PP > PVC (1.5wt%) > ABS (2.0wt%) > PC (Min 2.5wt%) 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 8 - 12 % 2. PAINT 1) Application and added quantity Process for applicationBio 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 1 wt% 2) 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 1) Application and added quantity Process for applicationBio 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% 2) 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 1) Application and added quantity Process for applicationBio Cera A must be putted in mixing process before crayon strength process Recommended Grade : Bio Cera A powder Recommended added quantity : 1.0 wt% 2) Key point To do raise antibiotic ability at high-dispersion process, it needs to be decided which operation would be reasonable? 5. PAPER 1) Application and added quantity Process for applicationIn 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 2) 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 togetherwith spread acid and Bio Cera A and effectively wet mill milling. 6. FIBER 1) Application and added quantity Process for applicationIt 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 : 1.0 wt% at resin 2) 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 1) Application and added quantity Process for applicationBio Cera A will be putted before rubber accelerator and other additive had puttedin rubber raw material, then fully mixing and subsequent final product strength. Recommended Grade : Bio Cera A powder Recommended added quantity : 1.0 wt% 2) Key point It must be maintained to put rubber accelerator at first before added Bio Cera Ainto product under the condition of full rubber process. Bio Cera A Master Batch Information1. Appearance: pellet 2. Practicable resins for application Styrene group: ABS, PS (GPPS, HIPS), and SAN etc. Olefin group: PE (HDPE, LDPE), PP etc. 3. Specific characteristics Due to a good dispersion, the antibiotic effect is good and it minimize the quality deterioration of the final product appearance by antibiotic agent. M/B has a good persistence, so it can be applied wildly application M/B has a good heat-resistance, so it is easy to molding and handling M/B is nontoxic and odorless, so the dealing of M/B is safe and it can be applied to food packing. The particle size and shape of antibiotic agent are designed to optimize to commercial use with resin, when molding. The color of M/B itself is light, so the coloring of the final product is easy 4. Application of antibiotic M/B Food packaging materials Plastics for household goods Stationery Construction materials Sanitary goods Electric home application Interior materials of automobile 5. Recommended Grade : Bio Cera A 10wt% concentrated M/B
