Doors and windows are one of the important peripheral protective
structures of buildings, which play the functions of wind and rain
protection, heat insulation, sound insulation, daylighting,
ventilation and so on. With the improvement of people's living
standards, the requirements for doors and windows in decoration are
higher and higher. As a widely used product, doors and windows have
broad market prospects due to their unique advantages. On the
premise of giving full play to its own advantages and improving
problems in the use process, new high-performance doors and windows
began to come into the sight of consumers.
High performance doors and windows mainly refer to the "three
properties", namely: wind pressure resistance, air tightness and
water tightness. At the same time, it has good thermal insulation
and sound insulation performance, and some also have intelligent
functions. The development of high-performance doors and windows is
mainly reflected in the following points:
The internal quality of profiles and their reasonable structural
design are the premise of manufacturing high-performance windows.
First, qualified profiles and advanced production technology
provided by regular manufacturers must be provided to ensure the
quality of high-performance doors and windows. In addition, the
wall thickness and structure of the profile are also very key. The
wall thickness directly affects its strength. On the one hand, a
reasonable structure can better play the role of heat insulation,
on the other hand, it can make each cavity have different uses.

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.
