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.

Parameters:

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.
