Publish Time: 2025-04-02
Blowing bottle masterbatch plays a vital role in bottle production and is the core support of the plastic bottle industry.1. Raw material selectionOrganic pigments: bright and soft colors, easy to use, suitable for making colored plastic products.Inorganic pigments: have advantages in light resistance, weather resistance, thermal stability, etc., suitable for outdoor products.Titanium dioxide: a commonly used white pigment, which can be adjusted by formula to obtain different whiteness, hiding power and other properties.Carrier selection: The carrier is the basic material in the blowing bottle masterbatch and needs to have good melting and dispersion properties. According to the final use and performance requirements of the bottle, select suitable carrier materials, such as polyethylene (PE), polypropylene (PP), etc.2. Production process optimizationMixing process: fully mix the raw pigment with the polymer carrier to ensure that the pigment is evenly dispersed in the carrier. Use efficient mixing equipment, such as high-speed mixers, internal mixers, etc. to improve mixing efficiency and quality.Melting process: Control the melting temperature, melting time and other parameters to ensure the stability and quality of the melt. During the melting process, the degradation and cross-linking reaction of the pigment and carrier should be prevented to ensure the performance of the masterbatch.Granulation process: The melt is extruded through the die head, and quickly cooled and cut into granules to form a masterbatch. Select appropriate die head and extruder parameters to ensure the shape and particle size of the masterbatch.Subsequent treatment: Dry and screen the masterbatch to improve the uniformity and screening efficiency of the masterbatch. When storing, avoid moisture, heat and other factors that affect its quality.3. Technological innovation and research and developmentDevelop new pigments and carriers: Continuously develop new pigments and carrier materials to improve the color effect and performance of blowing bottle masterbatch. Introduce environmentally friendly and degradable materials to meet the requirements of sustainable development.Improve production technology: Use advanced production technology and equipment to improve production efficiency and quality. Introduce automation and intelligent technology to reduce production costs and labor costs.Establish a full-process R&D system: From raw material selection, formula design, production process to product inspection and testing, establish a full-process R&D system. Strengthen cooperation with universities and research institutes, and introduce external innovation resources.4. Quality control and testingEstablish a strict quality control system: Strict quality control of the raw materials, production process, and finished products of blowing bottle masterbatch. Introduce advanced quality inspection equipment and technology to improve the accuracy and efficiency of inspection.Strengthen product inspection and testing: Detect and test the color effect, heat resistance, weather resistance, dispersibility and other properties of blowing bottle masterbatch. According to customer needs and industry standards, formulate strict product inspection standards and processes.In summary, optimizing the material properties of blowing bottle masterbatch requires starting from raw material selection, production process optimization, technological innovation and R&D, and quality control and inspection. Through the implementation of these measures, the color effect and performance of blowing bottle masterbatch can be significantly improved, meeting the market demand for plastic products of various colors, and promoting the sustainable development of the plastic bottle industry.
