Broken bridge aluminum doors and windows are mainly made of
heat-insulating broken bridge aluminum profiles and insulating
glass, which have the functions of energy saving, sound insulation,
noise prevention, dust prevention, waterproof and so on.
advantage:
1. Good thermal insulation;
2. There is a drainage outlet designed to ensure smooth drainage
and good water tightness;
3. The three-way sealing structure separates the water vapor
chamber, realizes the balance of water pressure and air pressure,
and prevents condensation and frost;
4. Metal material, heat insulation strip, high temperature
resistance, non combustion, fire prevention function;
5. Broken bridge aluminum doors and windows do not produce harmful
materials in the production process, and the materials can be
recycled, which belongs to green building materials;
6. High strength, not easy to deformation and corrosion, almost no
maintenance.
Disadvantages:
1. To achieve the thermal insulation performance of broken bridge
aluminum doors and windows, PA66 thermal insulation strip is
required, but its price is high, so the price of broken bridge
aluminum doors and windows is also high.
2. In addition, because PVC spacer is cheaper, some illegal
businesses may cut corners, so they need to pay more attention when
purchasing.

Compared with electroplating, the history of electroless nickel
plating is relatively short. Its real application in industry
abroad is only in the late 1970s and early 1980s.
The application of electroless nickel plating process is nearly ten
years later than the laboratory research results. After the Second
World War, American general transportation company became
interested in this process. They wanted to nickel the inner surface
of caustic soda cylinder, but the ordinary electroplating method
could not be realized. Five years later, they studied and developed
the technology of electroless nickel phosphorus alloy and published
many patents. In 1955, they created their first experimental
production line and made a commercially useful electroless nickel
plating solution. The commercial name of this electroless nickel
plating solution is "kanigen".
At present, electroless nickel plating has become a very mature
high-tech abroad, especially in the United States, Japan and
Germany, and has been widely used in various industrial
departments.
The industrial production of electroless nickel plating in China
started late, but it has developed very rapidly in recent years.
Not only a large number of papers have been published, but also a
national electroless plating conference has been held. According to
the statistics of the articles published in the fifth annual
electroless plating conference, there are more than 300
manufacturers, but this figure should be very conservative at that
time. It is speculated that the total scale of electroless nickel
plating Market in China should be about 30 billion yuan every year,
and develop at the rate of 10% ~ 15% every year.
Electroless nickel plating is a new technology to deposit nickel
phosphorus alloy coating by autocatalytic electrochemical reaction
with hypophosphite as reducing agent. Because the shoe plating
process is carried out under the condition of no current, it is
also known as electroless nickel plating, abbreviated as en
technology. It has the technical characteristics of strong deep
plating ability, good uniform plating ability, dense coating and
low porosity. Its application scope has been extended to various
fields of industrial production. At present, it is one of the best
surface treatments in the world.
