Talking about the manufacturing process of polyurethane load-bearing wheels

The advantage of PUR polyurethane load-bearing wheels is wear resistance, followed by oil resistance, hydrolysis resistance, high resilience, together with strong oxidation resistance, and does not affect the function after being placed for a long time. Roller bag polyurethane has a wide range of applications. The application areas of polyurethane products involve light industry, chemicals, electronics, textiles, medical, construction, building materials, automobiles, national defense, aerospace, aviation and many other fields. It covers basic industrial fields such as machinery, textiles, mining, and petroleum, and is widely used in emerging and special occupations such as photovoltaics, printing, sports, automobiles, ships, and national defense.

How can PUR polyurethane load-bearing wheels not degummed? It requires the correct technology and excellent material quality to ensure:

   1. Rubber-coated wheels after demoulding of PUR polyurethane load-bearing wheels! Need to continue to vulcanize in the vulcanization incubator for more than 12 hours.

   2. After the surface treatment of the iron core, it is necessary to heat it before gluing the glued surface.

   3. Put the iron core of the PUR polyurethane bearing wheel evenly coated with adhesive glue into the mold cavity until the pre-heated and fully mixed uniformly mixed liquid is poured. It is necessary to carry out anti-fouling control to prevent secondary oil pollution and dust impurities. Wait.

   4. The glued surface of the wheel core needs to be cleaned, decontaminated, alkalized, degreasing, acidified, and rust removed.

   5. In order to prevent the formation of bubbles in the adhesive layer, try to use the pressure vulcanization casting production process of polyurethane elastomer as much as possible, and the atmospheric air jet exhaust method shall not be used.

   6. Under the premise of always agreeing, carry out a one-month artificial aging vulcanization treatment.
