The production process of polyurethane thermal insulation elbows mainly includes the following steps:
1. Pre treatment: Screening, cleaning, drying and other treatments are carried out on the raw materials to ensure the quality of the raw materials.
2. Mixing: Mix raw materials such as polyether, polyester, isocyanate in a certain proportion, and add auxiliary materials such as catalysts and foaming agents.
3. Injection molding: Inject the mixed raw materials into the mold through an injection molding machine to form a prefabricated piece of polyurethane insulation pipe.
4. Cutting: Cut the finished product to a certain length for precision machining.
When producing polyurethane thermal insulation elbows, special attention should be paid to the following technical points:
1. Proportion control: The proportion control of polyurethane insulation pipes is crucial, and it is necessary to strictly mix according to the formula proportion, otherwise it will affect the performance of the product.
2. Control of injection temperature and pressure: The control of injection temperature and pressure has an important impact on the molding and performance of products, and precise control is required.
3. Time and temperature of heat treatment: The time and temperature of heat treatment are also important factors affecting product quality, and precise control is required according to product requirements.
