Suzhou ASA LI970 scratch resistant

Model performance: Co-extruded, good weather resistance and scratch resistance.
:r .< :r Detailed description of dd plastic raw materials< :r dd The source of plastic raw materials. Usually, plastic raw materials come from petrochemicals that use oil or natural gas as raw materials. They are a kind of polymer resin obtained through polymerization reaction. . Plastic definition: a polymer compound with synthetic resin as the main component. Polymer: Molecular weight > Medium molecular weight, low molecular weight, three forms of plastic: glassy state, high elasticity, viscous flow state instead of solid, liquid and gaseous states. It is impossible to have liquid and gaseous states (it will decompose before reaching that temperature) )
:r .< :r dd Overview
. It is copolymerized by styrene, acrylonitrile and acrylic rubber. Technically speaking, it not only maintains the main characteristics but also combines the advantages of weather resistance of acrylic, allowing the application of the product to be extended to outdoor uses. With more than 10 years of manufacturing experience, we have inherited Chimei's excellent quality and characteristics. Weather resistance, long-term usability, color stability, and good compatibility with / make it a broader and higher-value resin for automotive and motorcycle parts, construction parts, outdoor sports goods, gardening parts, outdoor antenna parts, and electronic and electrical products. , bathroom supplies, etc. In addition, the processing costs of secondary processing of painting and electroplating are reduced, making the product cost-effective and environmentally friendly.
:r .< :r dd identification
:r Surface finish is an important indicator to measure the quality level of various types of recycled material particles: the surface of high-quality recycled materials is smooth and smooth.
:r Transparency is an important indicator for measuring the quality of mid- to high-end recycled material particles: materials with transparency are of good quality.
:r The uniformity and consistency of color is an important indicator to measure the quality grade of colored recycled material particles: white, milky, white, yellow, blue, black and other colors.
:r Particle density is an important aspect for testing the level of regeneration technology: poorly plasticized particles are loose.
:r To see whether the recycled particles float or sink, water is used to test the filler content of the particles.
:r. For recycled materials, different recycled materials have different uses, because there is no unified standard and it is difficult to formulate unified standards to fully meet the user's process requirements.
:r.< :r dd molding conditions Five major elements
: r. Pressure Injection pressure: Control melt filling. Holding pressure: Control the melt to prevent backflow after filling. Back pressure: controls resin melting. Clamping pressure: Controls the mold from being punched apart
:r. Speed storage (r value): Controls resin melting. Firing rate: Controls resin filling. Holding speed: Control the recovery of resin during cooling. Mold opening and closing speed: controls the movement of the mold.
:r. Temperature tube temperature: controls the melting of plastic. Original drying temperature: control the original moisture content. Mold temperature: controls the crystallinity and cooling of the melt.
:r. Time injection time: control melt filling. Cooling time: Control the melt solidification. Mold opening and closing time: control mold transportation. Intermediate time: Control the pause after mold opening.
:r. Position injection range: control melt filling. Mold opening and closing process: control the mold process. Robotic process: controls the clamping head.
:r .< :r dd's application fields
:r .Automotive field: After long-term wind erosion, it will not turn gray like specially treated aging-resistant ones (due to wind erosion or Water flow causes many microscopic cracks and cavitation on the surface). Typical applications are exterior mirrors, radiator grilles, tail baffles, lampshades and other external parts that are exposed to harsh conditions such as sun, rain, strong winds, etc. It has gradually extended to motorcycle panels, camping cars, small boat hulls, surfboards and other fields.
:r. Horticulture field: Proven to be particularly suitable for gardening irrigation equipment and lawn cutter casings.
:r. Electronic and electrical fields: priority is given to the casings of durable equipment, such as all-weather casings of sewing machines, telephones, kitchen equipment, satellite antennas, etc.
:r. Construction field:/Admixtures have been used in roof wainscoting and window materials for more than 10 years abroad.
