1. Introduction to refrigerator foaming process<\/b><\/strong><\/h3>

Modern refrigerators generally use polyurethane high-pressure foaming technology <\/strong>to form the middle insulation layer. The foaming process involves precise control of multiple parameters, including:<\/p>

  • Foaming time<\/li>
  • Mold temperature<\/li>
  • Ambient humidity<\/li>
  • Raw material ratio and mixing uniformity<\/li><\/ul>

    If these factors are not controlled accurately, especially if the foaming time is too long or too short <\/strong>, it may lead to:<\/p>

    • The foaming layer is not fully matured, resulting in residual bubbles;<\/li>
    • The foaming reaction is too strong, resulting in an obvious “bulge” on the back;<\/li>
    • There is an excess of polyurethane foaming agent, resulting in material overflow.<\/li><\/ul>

      2. Common abnormal phenomena<\/b><\/strong><\/h3>

      Exception Type<\/b><\/strong><\/p><\/td>

      Possible manifestations<\/b><\/strong><\/p><\/td>

      Cause Analysis<\/b><\/strong><\/p><\/td><\/tr>

      Bulge on the back<\/p><\/td>

      Local convex deformation on the back<\/p><\/td>

      The mold is not tightly locked, the pressure is uneven, and the time setting is abnormal<\/p><\/td><\/tr>

      Too many bubbles<\/p><\/td>

      Slightly bulging, loose structure<\/p><\/td>

      Uneven foaming, insufficient aging time, water content in raw materials<\/p><\/td><\/tr>

      Overflow problem<\/p><\/td>

      Foam material seeps out from the gap<\/p><\/td>

      Excessive injection volume, mold sealing problem<\/p><\/td><\/tr><\/tbody><\/table>

      3. User handling suggestions<\/b><\/strong><\/h3>

      Although foaming layer abnormalities mainly occur in the production process, if users encounter minor problems during use, they can also try the following solutions according to the specific situation:<\/p>

      Minor foaming overflow <\/strong>: Use clean fingers to gently press the overflow area to expel some of the gas and wait for it to naturally shrink. Please pay attention to safety when operating and do not damage the surface paint film.<\/p>

      Severe bulging or loose structure <\/strong>: If the refrigerator has large bulges or is accompanied by cracks or door deformation, you should immediately contact the brand’s after-sales service for professional inspection and repair.<\/p>

      Precautions during use <\/strong>:<\/p>

      • Avoid frequent power outages and restarts;<\/li>
      • Do not shake or move the refrigerator violently;<\/li>
      • Check the refrigerator back panel regularly for any abnormal deformation.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
