1. Silicone color printing-the characteristics of silicone:
Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance, etc. The outstanding performance of silicone rubber is the wide use temperature, which can be -90 ℃ (or lower temperature) to +300 Long-term use at ℃ (or higher temperature). However, the mechanical properties of silicone rubber are poor in tensile strength and tear strength. At room temperature, its physical and mechanical properties are not as good as most synthetic rubbers. In addition to nitrile silicon and fluorosilicone rubber, the general silicone rubber has poor oil resistance and solvent resistance. Good, so silicone rubber is not suitable for occasions under ordinary conditions, but it is very suitable for many specific occasions.
It is worth mentioning that in biomedical engineering, polymer materials have a very important role, and silicone rubber is a particularly important class of medical polymer materials. It has excellent physiological inertness, non-toxic, odorless, and no Corrosion, anti-coagulation, good compatibility with the body, can withstand harsh disinfection conditions. It can be processed into tubes, sheets, films and special-shaped components according to needs, and can be used as medical instruments, artificial organs, etc. Now there are special medical grade silicone rubbers at home and abroad.
2. silicone color printing-the development of silicone:
In recent years, the silicone rubber industry has achieved remarkable results. With the rapid growth in consumption, the silicone rubber industry has begun to transform from high-performance specialty rubber to mass synthetic rubber, becoming one of the most widely used rubber varieties. It is reported that from the perspective of rubber consumption, natural rubber accounts for 41.8%, styrene-butadiene rubber and cis-butadiene rubber together account for 28.4%, while silicone rubber is usually only used in a few non-tire areas such as building sealants and conductive buttons, accounting for only rubber 6.4% of total consumption. Therefore, as silicone rubber replaces other types of rubber in some non-tire segments, its consumption will surely increase exponentially, and the market space will be further opened. In this regard, industry insiders also agree with the above views. It is estimated that by 2015, silicone rubber will account for 10% to 15% of the total domestic rubber consumption, that is, silicone rubber consumption is expected to reach 1 million to 1.5 million tons,
By 2020, the proportion of silicone rubber in total rubber consumption is expected to reach 20% to 33%, that is, the consumption of silicone rubber is expected to reach 3 million to 5 million tons. In other words, the development potential and long-term development of the silicone rubber industry are very attractive, and its rapid development will also have a profound impact on the upstream and downstream industries. In fact, the linkage effect of the upstream and downstream industries of the silicone rubber industry has begun to gradually appear. Some experts pointed out that the biggest highlight of the development of the silicone rubber industry is that it can greatly increase the domestic self-sufficiency rate of rubber. According to statistics, if the proportion of silicone rubber in China's rubber consumption is increased from 6.5% to 33% by 2020, then the overall domestic self-sufficiency rate of China's rubber can be increased from the current about 50% to more than 80%, thereby greatly alleviating rubber The tight supply situation reduces the production cost of the rubber processing industry. It can be seen that the development of the silicone rubber industry is not only a single development of a single industry, but also involves the joint development of multiple industries, which has far-reaching significance for enhancing the profitability of the rubber processing industry and improving the quality level of rubber products.
