1. Selection of ASA resin
ASA resin is the main component of ASA synthetic resin tiles, and its performance directly affects the weather resistance, UV resistance, color stability and mechanical strength of tiles. When manufacturers choose ASA resin, they will consider the following aspects:
Source of raw materials: Prioritize well-known and reputable Resin Tile manufacturers to ensure the purity and stability of raw materials. These manufacturers usually have advanced production technology and strict quality control systems to provide high-quality ASA resin.
Chemical composition: ASA resin is a ternary copolymer of acrylonitrile (ACN), styrene (ST) and acrylate (A). Manufacturers will pay attention to the ratio of these three monomers to ensure that ASA resin has excellent weather resistance, chemical corrosion resistance and mechanical strength. Generally, the higher the acrylonitrile content, the better the weather resistance and chemical corrosion resistance of ASA resin; the styrene content affects the transparency and processing performance of the resin; the acrylate content helps to improve the flexibility and impact resistance of the resin.
Physical properties: Manufacturers will test the tensile strength, bending strength, impact strength and other physical properties of Resin Tile to ensure that it meets the production requirements of ASA synthetic resin tiles. In addition, they will also pay attention to parameters such as the heat deformation temperature and melt flow rate of the resin to evaluate its processing performance and thermal stability.
Weather resistance and color stability: The weather resistance and color stability of ASA resin are important considerations for manufacturers when choosing. High-quality ASA resin can still maintain its color stability and physical properties after long-term exposure to harsh environments such as ultraviolet rays, moisture, heat, and cold.
2. Selection of other auxiliary materials
In addition to ASA resin, the manufacture of ASA synthetic resin tiles also requires other auxiliary materials, such as plasticizers, stabilizers, antioxidants, pigments, etc. The selection of these materials is equally important because they affect the processing performance, service life and appearance quality of the tiles.
Plasticizer: used to improve the flexibility and processing performance of the resin. Manufacturers will choose plasticizers with good compatibility with ASA resin to avoid problems such as stratification or precipitation during use.
Stabilizer: used to improve the thermal stability and light stability of ASA resin. Manufacturers will choose stabilizers with excellent heat resistance and light resistance to ensure that the tiles are not easy to age or discolor during long-term use.
Antioxidants: used to prevent ASA resin from degrading due to oxidation during processing and use. Manufacturers will choose high-efficiency, low-toxic antioxidants to ensure the safety and durability of tiles.
Pigments: used to color ASA synthetic resin tiles. Manufacturers will choose environmentally friendly and weather-resistant pigments to ensure that the colors of tiles are bright, long-lasting and not easy to fade.
3. Quality control of raw materials
When selecting raw materials, manufacturers will also conduct strict quality control. This includes:
Raw material inspection: Sampling inspection of each batch of raw materials to ensure that they meet production requirements and quality standards.
Supplier management: Regular evaluation and audit of raw material suppliers to ensure that their production capacity and quality control system meet the requirements.
Storage management: Proper storage and management of raw materials to prevent them from moisture, deterioration or contamination.
