Product introduction
Features
SMC, that is, sheet molding compound, is made of unsaturated polyester resin, glass fiber roving, and other matching materials through special equipment SMC forming unit, and then thickened, cut, and put into metal Made by high temperature and high pressure curing. SMC and its molded products are emerging fiberglass-reinforced plastics, commonly known as FRP, and its processing methods can be divided into several processing methods: hand lay molding, injection molding, pultrusion molding, winding molding, resin transfer molding, compression molding . SMC and its molded products have the following characteristics: light weight, high strength, accurate size, good batch quality consistency, and products can achieve zero shrinkage. It has a level of mechanization and a higher degree of automation than A-level surface. It is suitable for products with high surface quality requirements, large output and uniform thickness.

High precision, high efficiency, high gain
The most important job of using SMC in the manufacture of antennas is to give full play to its characteristics from product design and process manufacturing and to meet the requirements of antenna type high precision. In the mold size design, the shrinkage rate of the material and the SMC molding shrinkage rate have been considered, the shape of the SMC antenna reflection surface deviated from the original design paraboloid after molding is small, that is, the accuracy of the SMC molded antenna is completely guaranteed by the mold accuracy . The rms value of the integral reflection surface of the molded SMC antenna is 0.25mm, the rms value of the monolithic reflection surface of the split antenna is less than 0.3mm, and the rms value of the reflection surface after assembly is less than 0.6mm.
Anti-corrosion
The traditional antenna materials such as aluminum plates and steel
plates are metal materials. In terms of acid resistance, alkali,
salt, and corrosion resistance, SMC is a non-metal dielectric
composite material. The Pikington laboratory in the United States
used infrared to analyze the surface of the SMC material and found
that its surface was covered by additives, resins, and very fine
calcium acid fillers. It had good acid resistance, water
resistance, and corrosion resistance. The antenna reflection made
of this material solved the problem. The shortcomings of the
traditional metal material antenna are easy to corrode. In coastal
areas, rainy, humid areas and acid rain areas, the corrosion
advantages of the SMC molded antenna are particularly prominent.
The Bodlin Company of the United States has conducted more severe
corrosion protection tests. The SMC molded antenna sample was
placed in the environment of 130 highly corrosive chemicals at an
environment temperature of 50 ° C. The results showed that the test
sample changed only slightly or not.
long life
The average aluminum plate antennas in coastal areas range from 2-3
years to as many as 4-6 years. Generally, they will be damaged due
to salt fog erosion and aging. The most obvious example is the
cable television (CATV) in Taiwan. In the mainland, it is estimated
that there are about 1,000 satellite TV receiving antennas in the
whole island, all of which were built in the mid-1980s. They are
all aluminum plate antennas. By the early 1990s, they had been
replaced one after another. This time, SMC molded antennas were
used. The company has supplied hundreds of antennas). The service
life of SMC molded antennas is generally more than 15 years; the
SMC molded antennas trial-produced by PRODLIN in 1985 are still in
normal operation, and they are subject to typhoons and rainstorms
every year.
Strong wind resistance
During the molding process of the antenna reflection surface,
multiple longitudinal and circumferential rib structures are
designed. According to the calculation of the structural strength,
the SMC antenna can withstand the wind load of up to 45 m / s,
which shows its remarkable structural rigidity and strength.
Reflective layer technology
The SMC antenna reflection surface uses metal aluminum mesh as the
electromagnetic wave reflection layer, and the aluminum mesh in the
finished antenna is evenly embedded under the surface SMC, which
can reflect electromagnetic waves and isolate the atmosphere, which
plays a good protective role.
Easy to install and transport
Because the SMC antenna adopts the membrane pressure technology
under high temperature and high pressure, its material
characteristics and processing technology determine that the SMC
antenna has unparalleled consistency with other antennas, which not
only ensures the accuracy and high gain of the antenna, but also is
very easy to install debugging. SMC is commonly known as "glass
fiber reinforced plastic", which has the characteristics of
non-deformation, which eliminates the adverse effects of the
antenna deformation on the satellite receiving system during
transportation.
