Antibacterial plastic is a type of plastic that can inhibit proliferation or killing effects that can contain bacteria, mold, algae, and even viruses that are stained on the surface of plastic surface in use. It maintains its own cleanliness by inhibiting the reproduction of microorganisms. Antibacterial plastic is mainly obtained by adding antibacterial agents to ordinary plastic.
Why is plastic products prone to accumulating bacteria
The surface of the plastic products is smooth. Although it is easy to clean, the bacteria on the surface can still survive and accumulate.
Plastic products can easily absorb oil on its surface, all of which are rich in nutritional microorganisms such as Golden Polyrium, E. coli, E. Bacillus, Bacteria, Symagonic Bacteria, Octoburate, and Poor bacteria and other pathogenic microorganisms. Material. It is difficult to completely wash even if it is rinsed with water in life or disinfection.
Antibacterial plastic nature
In the use of antibacterial plastics, first meet the necessary requirements for physical, chemical, machinery and other properties when using plastic as basic materials. At the same time, it is necessary to consider the requirements of the special function of antibacterial and the additional factors generated.
Therefore, antibacterial plastic must have good mechanical strength appearance, chemical stability, and good processed. In terms of antibacteriality, antibacterial plastics are required to adapt to the use environment, and they should have efficient, broad -spectrum, and long -term antibacteriality.
Because antibacterial plastic contains a small amount of antibacterial agent, the antibacterial agent used to be used to achieve the prescribed sanitary safety, and the ultimate antibacterial plastic product meets the requirements of non -toxic, odorlessness, and harmless environment.
Antibacterial plastic performance evaluation method
01 Measurement of conventional performance
The conventional properties of antibacterial plastic, such as melt activity, stretching strength, stretching volume, fracture and elongation, gap intensive intensity, bending strength, bending modulus, hardness, chroma, surface smoothness, etc. The test standard is executed.
02 Evaluation of processing performance
As the antibacterial plastic is different, its processing technology and processing characteristics are also different. The processing performance mainly depends on the nature of the plastic material used. It can be evaluated by determining the melting flow degeneration in the laboratory, but it is more direct and important for actual processing to obtain the basis of processed evaluation. The requirements for the processing performance of injection, extrusion process and material processing are very different.
03 bacteriostatic circle experiment
Determine whether a substance has antibacterial activity can usually be performed by the method of antibacterial circular experiments in microbiology. In terms of qualitative, the antibacterial rate of antibacterial rate can not be obtained. The size of the bacteriostatic ring represents the strength of the measured material to be tested. This method has the characteristics of fast and simple, and is often used in drug screening such as antibiotics. In the early days, some people used this method to study the antibacteriality of antibacterial plastic. The antibacterial circle method cannot be obtained by the quantitative results of antibacterial rate. Although the size of the bacteriostatic ring can reflect the good or bad of the antibacterial effect under certain conditions, the value of this value is poor between different antibacterial substances. Experiments show that some antibacterial plastics do not form obvious bacteriostatic ring.
04 film method
At present, among the many antibacterial testing methods, the film method is closer to the actual situation. It is a test method for quantitative measurement of antibacterial plastic antibacterial. Waiting for external factors can objectively reflect antibacterial plastic antibacterial functions. The film method first uses bacteria to contact the surface of the sample. After the film is saved for 24 hours, it is carried out. The results of a relatively vacant parallel experiment were obtained to achieve antibacterial rates of antibacterial plastic. Test bacteria are StaphyLococcusaureus and Escherichiacoli.
The film method was proposed by the Japanese Antibacterial Products Technology Agreement (SIAA) in 1995 and has been modified several times. The National Engineering Research Center of the Engineering Plastics has done a lot of research on this basis, and refers to GB15979-1995 "One-time Sanitary Products Sanitation Standards" formulated the "Antibacterial Plastic Antibacterial Rate Test Method (Film Method)" in 1998 Essence The test results are repetitive and the data is reliable, which plays a good role in practice.
05 Anti -mildew performance test method
Plastic mold anti-mildew performance test can refer to GB2423.16-1990 "Basic Environmental Test Specification of Electrician Electronics Products J: Long Mold Test Method" ISO846-1978 (E) "Test of the behavior of plastic under the action of fungi and bacteria-use intuitive use of intuitive use Evaluate the method of inspection or use of measurement quality or physical changes ". There are 8 types of mildew testing bacteria in the National Engineering Research Center of Engineering Plastic National Engineering Research Center (1999), including ASPERGILLUSNIGER, Aspergillusterreus, and AureBasidiumPullulans ), Wan's Paceilomycesscarioti, Penicilliumfunicolosum, Trichodeimaviride, Penicilliumochloron, Trichodermavirid (Trichodermavirid), anti -mold. Level 2, 3. The mildew levels are level 0. When the sample sample is determined, it will not observe the growth of mold by 50 times when the results are determined.
The antibacterial parent grains of Rizize make the antibacterial agent into a female granules, which have good heat resistance, good dispersability, good filtration performance, good antibacterial effect, high long -term effect, and washing resistance. Antibacterial mother particles are widely used in plastic products, chemical fibers, non -woven fabrics, etc., which can make their products have long -term antibacteriality and have become an indispensable necessity for people's daily life.
Yancheng Ruize Mother Green Co., Ltd. specializes in the production of fine -colored maternal grains, non -woven female grains, and functional mothers. Since its establishment, it has always adhered to the "pursuit of extreme and striving for perfection". The medical and hygiene non -weaving cloth industry has stable and reliable quality, advanced technology, and is well received by customers. Yancheng Ruize Mother's Trust is worth your trust!
