《Breathable ceramic, "the porous ceramic" 》 # Chapter Third #
＊ How porous ceramics can help upgrade the technology industry ＊
The term "porous ceramics" is unfamiliar to the general public, and there is not much contact even by ceramic workers. As the first chapter says, in addition to industrial ceramics, daily life ceramics are almost hundreds of impermeable "solid ceramics." Most people know what it is the "ceramic filter", but will never call it "porous ceramics", in fact, it is the use of ceramic wall thickness inside the pores so that the water flow over the block than water molecules larger foreign bodies, purify the water quality of the "porous ceramics."
Since it will be permeable to breathe, it is a simple physical phenomenon, but why is "ceramic filter" not called "Breathing porous ceramics"?
The definition of "breathing porous ceramics" itself requires a certain degree of set conditions, is generally "ceramic filter" does not have.
Give two examples of "Anti-High Pressure" and "Anti-particles":
1. "Anti-High Pressure"
A 2000-liter water tower is placed on a four-story building, and the internal tap water passes through an inch diameter, a wall thickness 3mm high-pressure water pipe, and the pressure flowing to the four floor (between the height and drop of about 3~4 meters) is about 0.15 kg of atmospheric pressure per cubic centimeter, with the increase of the high and low drop. When flowing to the first floor, the water pressure increases to more than or equal to 1.05 kg of atmospheric pressure.
Home water purifier Construction, "Ceramic filter" design placed in a high-pressure barrel, tap water through a diameter of one inch water pipe (Ø25.4mm) into the diameter of 8mm water purifier water pipe into the high-pressure barrel, through the "ceramic filter" outside the wall and then through the diameter of 8mm water purifier high-pressure pipe outlet, due to the large diameter of the pipe Water purifier in and out of the water mouth is small, tap water pressure has been in large diameter conversion small caliber to obtain decompression, "Ceramic filter" in the cavity also obtained water pressure balance, each square centimeter subjected to atmospheric pressure is roughly less than or equal to 0.1 kg.
"Breathing porous ceramics" the safety of each cubic centimeter can not be less than 2.5 kg, excellent or even withstand up to 5 kg of atmospheric pressure. General "porous Ceramics" operation of high-pressure air between 2 kg up and down, in other words, including the import of most of the "Ceramic filter" under this pressure, almost will burst.
2. "Anti-Particles"
High-tech products process environment The most afraid of particles, all clean rooms are in a negative pressure state, and according to product category needs, distinguish between different levels, in a cubic foot space can be allowed to have several less than or equal to 0.5 microns of dust particles, to define the clean room level.
The Semiconductor industry manufacturing wafer environment is the most demanding, according to international norms, each cubic foot space only allows less than 0.2 microns of dust particles 2, less than or equal to 0.1 microns in 10 of the clean room is the ISO 1 "ultra-clean room" known as Class 1. Such as the TFT-LCD light power Plant clean room allows 100. 0.5 micron particle units, known as Class 100.
How small is a 0.5 micron (500 nm) speck of particles?
The minimum object size can be seen by normal people with the naked eye 200 microns; 10 times times the magnifying glass, can observe more than or equal to 25 micron objects; In other words, 0.5 micron-sized dust particles need an optical microscope to see.
The combination of ceramic materials is mineral sintering, even if the burning of solid ceramics after the non-dust are quite difficult, not to mention the porosity of ceramics.
The production of high-pressure "porous ceramics" is very difficult, coupled with the injection of suction through high pressure "no particle" (ceramic pores do not produce particles) that is even more difficult, not to mention more than 15 sum conditions:
1. Pore size 2. Porosity 3. Structural strength 4. Crystal phase 5. Coefficient expansion
6. Anti-temperature domain 7. Resistivity 8. Homogenization 9. Flatness 10. Anti-High Pressure 11. Anti-Particle 12. Uniform color 13. Adsorption capacity 14. Air film rigidity 15. Energy saving performance ...,There are more conditions.
2008 years ago, the "porous ceramics" market, almost included by Japan, the United States, Germany, Israel, which dominates the core technology of the market, Taiwan must buy abroad, including the limited use of Japanese ingredients, dominance or foreign.
Relying only on specific suppliers to specify raw materials, everything is subject to foreign countries, there is no other choice, cannot grasp the change at will, flexible modulation, cannot be called "own core technology."
Although the TSMC strategy is defined as a wafer market foundry, it has the core technology that transcends Intel, once the world's number one bully, leaving Samsung, South Korea, far behind.
In the 1980, before China opened its inland market to the world, "Taiwan Yingge Ceramics Export" world-famous, 1960-1980 years Yingge ceramics is the main production place of daily porcelain in the United States, 1980 years later, Taiwan businessmen have to invest in the mainland, Yingge export market has gradually ceded to China, Those who remain in Taiwan ceramic industry must face the reality of technology to enhance industrial transformation.
For a long time accustomed to OEM mode, no R & D Capabilities of Taiwan ceramics industry, to transform into a high-tech industry is not easy to do? To hope that the government's capital and technical support, according to the government administrative practice, will open more, Paper work than practice, and be detained for fear of profit specific manufacturers hats, coupled , To be correct, government support operators to do "new products" rather than "new industries".
Traditional ceramic manufacturers, self-created "local own core technology"? Is that possible?
According to the 28 law, many of Taiwan's industries that try to transform seem to be so, and do not doubt that success is less, and many are killed.
Taiwan's local "science and Technology Ceramics" industrial technology, there is an opportunity to compete with foreign factories?
In the case of "Did not receive government related units and consortium support," How do you move the first step?
