What Material is Used in the Polymer Composite Manhole Cover?

What material is used in the polymer composite Manhole Cover?
The Composite Manhole Cover is in the form of SMC sheet. It is added with resin, calcium powder, magnesium oxide and other materials. It is made in the form of SMC sheet. It is placed in the reaction chamber for 48 hours. After high temperature molding, it is made into the SMC composite. Material manhole cover. In terms of usability and aesthetics, the composite manhole cover has strong plasticity, strong coloration and rich color conversion. The whole material is colored instead of sprayed, so the color is lasting, the surface of the product is smooth, the hand feels smooth and delicate, and the surrounding color of the floor and The floor material can be kept consistent, beautiful and practical. The product has a long service life. After testing by the National Construction Engineering Quality Supervision and Inspection Center, SMC sheet products can withstand 2 million anti-fatigue tests, and the service life can reach more than 30 years! It is the ideal replacement for cast iron manhole covers.

There are many factors to consider when installing a composite manhole cover. For example, the problems that usually occur after a period of installation are: the cover is sunken, the manhole cover is displaced, the manhole cover is abnormal, the surface of the manhole cover is missing, the friction is too small, and it is easy to slip on it. Wait. In consideration of these factors in advance, special care must be taken when installing. What kind of material is the polymer manhole cover? For example, the surface of the composite manhole cover has patterns and handwriting. During construction, care should be taken not to damage the surface pattern and font. You can find a thin piece of iron or spray a layer of tar on the surface of the manhole cover. Or cover the manhole cover with a plastic film to prevent the cement from sticking to the manhole cover, and to damage the surface font or friction pattern. The outer well of the manhole cover shall be constructed in strict accordance with the design and construction drawings, and the dimensions shall not be arbitrarily changed to ensure that the manhole cover is opened or closed freely and flexibly.
When the manhole cover is especially used for the construction of the composite manhole cover, the installation must be carried out by means of some machines because of the heavy weight. It is necessary to pay special attention to the construction machinery not to touch the surface of the manhole cover to avoid damage to the surface of the manhole cover.
