Usage Instructions
Manufacturing Antibacterial Plastics
Drying: Before use, dry the antibacterial masterbatch at 80°C for 24 hours; a forced-air oven or vacuum oven may be used for this purpose.
Mixing: Blend the dried antibacterial masterbatch with the base resin (matrix material) at an addition ratio of approximately 45%, then mix thoroughly with the plastic pellets.
Molding: Process the mixture into antibacterial plastic products using techniques such as injection molding, blow molding, or similar methods.
Manufacturing Antibacterial Textiles
Blend Spinning Method: Mix the antibacterial masterbatch-along with additives such as dispersants-into the fiber matrix resin. Produce antibacterial fibers via melt spinning; this method is suitable for fibers such as polyester and polypropylene.
Composite Spinning Method: Employ a composite spinning process that combines fibers containing antibacterial components with ordinary fibers to create antibacterial fibers with various structural configurations.
Precautions
Select the Appropriate Type of Antibacterial Masterbatch: Different types of antibacterial masterbatches are suited for products made from different materials; therefore, during processing, select the specific masterbatch that corresponds to the material of the intended product. Additionally, note that certain antibacterial masterbatches are not heat-resistant and should not be used in manufacturing stages involving high temperatures.
Determine the Appropriate Addition Ratio: Adding too little antibacterial masterbatch will compromise its antibacterial efficacy, whereas adding too much may negatively affect the moldability of the plastic or fiber. Consequently, the optimal addition ratio must be determined based on the specific requirements of the product and the prevailing processing conditions.
Ensure the Antibacterial Masterbatch is Dry: Prior to processing, ensure that the antibacterial masterbatch is thoroughly dry; if it is damp, it must be dried using a forced-air oven or standard drying oven. During storage, maintain a dry environment to prevent the masterbatch from absorbing moisture, which could adversely affect its performance.
