Process requirements and precautions for polyurethane castors

1.Air hole and bubble: the material mixing method and mixing time do not make the material mixed evenly; During construction, agitators with low power and rotating speed shall be used. Another reason is that the treatment of the base course is not clean. Before coating, the base course should be carefully cleaned without floating sand and dust, and there should be no pores on the base course. The pores in each layer of the coating should be treated according to the process requirements to prevent leakage caused by the damage of the coating.

2. If precipitation is found in the materials, they shall be mixed evenly before use, so as not to affect the quality.

3. Attention shall be paid to fire prevention during construction. Construction personnel shall take protective measures. The construction site shall be well ventilated to prevent solvent poisoning.

4. Damage: during the layered construction of the film waterproof layer or after the construction of all the film, the film is damaged by people operating activities before the film is cured, or placing tools and materials. Scratch. The integrity of the coating shall be protected during construction.

5.Both materials a and B are packed in iron drums, which are flammable and toxic. They should be sealed during storage and placed in a cool, dry place without strong sunlight.
