Ⅰ. Product Classification:
It used to to produce casting type polyurethane Elastomer products with MOCA or BDO as chain extender.
Ⅱ. Functions and features:
-
1. The raw material tank adopts the hot air circulation of electric heating(patented technology), which makes heating faster, efficient, energy saving 50%, safe and environmental protection.
-
2. High-temperature resistant low-speed high-precision metering pump; accurate matching, flexible adjustment and measurement accuracy error: ≤±0.5%.
-
3. Independent PLC control system in the branch temperature controller of each group , with special electric heating system, oven, piping and vales which can be adjusted separately; multi-point temperature control device is used to ensure that the raw material to maintain a constant temperature throughout the cycle process; temperature error: ≤2℃.
-
4. The mixing device is reasonably designed: the mixing head is light and durable.
-
5. Equipped with the color paste control system and the color paste directly goes into the mixing device; different colors can be switched at any time; the mixing is uniform and the metering is accurate.
-
6. Adopt the imported PLC controller to monitor the entire control system; it will automatically make judgment of abnormity, diagnosis and alarm, abnormal factors display, PLC module control, casting, automatic cleaning and air impact; stable performance and strong operability.
-
7.Equipped with a vacuum degassing system.
Ⅲ. Application:
PU elastomer casting machine is fit for making Rubber roller, high load solid core wheel, mines sieve plate, hydraulic seal ring, photovoltaic guide pulley wear-resistant materials in metallurgy, printing and dyeing, spinning, mine, paper-making industry.
