According to the present scientific and technological situation and service condition of nodular cast iron well cover, the future development direction of nodular cast iron well cover must have the following aspects:
1。 Diversity of materials
Now there are many kinds of ductile iron manhole covers in the market, such as: cast iron manhole cover, ductile iron manhole cover, glass fiber reinforced plastic manhole cover, resin manhole cover, cement manhole cover, magnesite manhole cover, etc。 with the progress of science and technology, there will be more ductile iron manhole covers in the future, each with its own characteristics。
Now when it comes to nodular well covers, what are the main problems? Anti theft, because there are too many problems in the theft of nodular cast iron manhole covers, so in the future, no matter what material or technology, the anti-theft problem of nodular cast iron manhole covers must be solved, otherwise there will be no market.
Even if the mainstream ductile iron well cover has only one color, it is certain that the future ductile iron well cover (or with the development of science and Technology) will be colorful, gorgeous and very beautiful, just like the color TV replaces the black-and-white TV and the smart phone replaces the ordinary mobile phone。 The trend is irreversible。
