According to foreign media reports, graphene is a very useful material. It is made of a layer of carbon atoms connected by a layer of atoms. It has been proven to prevent steel rust. Soon, it can also be used to prevent bacteria from corroding metal pipes. In sewage treatment facilities such as sewage treatment plants, microorganisms called sulfate-reducing bacteria often parasitize the internal surfaces of pipes and other equipment.

These microorganisms form in the form of so-called "biofilms" within 10 days after the pipes are cleaned and then continue to degrade these pipes in two main ways.
First, microorganisms extract electrons from metal surfaces when they breathe. Then, when bacteria consume organic matter in water, they produce corrosive hydrogen sulfide.
Although protective polymer coatings can be applied inside the pipeline, these coatings themselves may also be degraded when bacteria consume the plasticizer in the pipeline. In addition, over time, such coatings can become brittle and crack, fall off, and eventually enter the water stream.
Given these limitations, Govind Chilkoor, a scientist from the South Dakota School of Mines and Technology Research, turned to graphene as a coating material. In laboratory tests, he found that even a layer of graphene less than 1 nanometer thick can effectively prevent sulfate-reducing bacteria from attaching to the inner surface of metal pipes. Chilkoor pointed out that graphene has very good antibacterial properties, "it will cause oxidative stress and cause bacterial death."
In addition, considering that graphene is one of the strongest man-made materials, it should be much more durable than the polymers currently used for protective coatings. In addition, since graphene has good thermal conductivity, its performance should be superior to polymers when used in heat exchange pipes.
Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.
Hospitals
Airports
Retail centers
Pharmacies
Hotels
Grocery stores
Hardware stores
Sporting goods stores
And more
In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.
Hongfa will only dispatch highly trained CE Certified inspector/technicians to inspect, repair, service or replace automatic doors. This ensures we provide the most efficient and safest door repair for your business.
