The reason for damage: Hainan ductile iron manhole cover is a widely used product so far, but due to long-term exposure to rain, the product will inevitably be corroded by rain and the sun, and thus be damaged to some extent. If we can not solve this problem well, we believe that its use will be greatly affected, Next, let's discuss with you the specific causes of damage.

1. Hainan nodular cast iron well covers are corroded by the gas in the well, including thermal well covers, water supply well covers, telecommunications well covers, community well covers, sewage well covers, etc. If the following gases are particularly corrosive, they will be corroded by the gas, especially the presence of chloride ions in the environment: chloride ions are widespread, such as salt, sweat stains, sea water, sea breeze, soil, etc. It corrodes rapidly in the presence of chloride ions, even surpassing ordinary low-carbon steel. Therefore, there are requirements for its use environment, and it needs to be wiped frequently to remove dust and keep it clean and dry.

2. Hainan nodular cast iron manhole cover is also one of the common reasons for damage. There are more and more cars on the road now. Especially in big cities, if there is no waterproof, anti-theft, shock proof, rust proof well cover used on the road, the result is that there are more and more black holes on the road.

3. It is very important to make the material of nodular cast iron manhole cover. To cast with good materials, it is not allowed to use any unscientific materials, such as composite materials, cement, nodular cast iron, magnesite, etc. The products made of these materials are not resistant to aging and impact, and will be damaged automatically after a long time. There is a steel skeleton inside these products, which will provide opportunities for some lawless people to steal and get rich. Thus causing losses to the country.

There is a problem with Hainan nodular cast iron manhole cover. We should think out corresponding countermeasures to deal with the problem in time. In fact, the method to prevent manhole cover damage is very simple. One is to ensure that absolutely qualified products are put on the market, and the other is to carry out frequent maintenance, and replace the manhole cover as soon as there is any sign of damage. I hope that through the above learning, we can help in the future application. There's more Please pay attention to the official website of Hainan Plastic Industry Co., Ltd.
