What is good for fishing nano bleaching?
Nano-materials, micro-particles, and substances with sizes between 0. 1 and 100 nm. Nano-materials have peculiar or unusual physical and chemical properties that traditional materials do not have. For example, copper, which is originally conductive, is not conductive when it reaches a certain nanometer level, while silicon dioxide and crystals, which were originally insulated, begin to conduct when it reaches a certain nanometer level.
Then, let's look back at the "nano float". At present, the so-called "nano-float" is basically a kind of foam material whose chemical composition is methacrylimide. This material has low density, light weight, low water absorption, little influence by thermal expansion and cold contraction, and high compressive and torsional strength, but it has nothing to do with nano-materials. The reason why we are fascinated by nano is our national conditions and we are moved by high technology. The so-called nano-bleaching is simply bleaching made of foam materials.
So, is the "nano-float" better than the traditional float?
Because our purposes are different, there is no standard answer to this question. We can only compare their differences and choose according to our own reality.
1. A floating body with the same size as a traditional floating body has greater buoyancy, which is 1.5 times that of balsa wood. In layman's terms, it is more sensitive.
2. The water absorption of "nano" materials is very small, so there is no need to worry about floating manuscripts. Traditional bleaching has the problem of poor draft.
3. Floating bodies such as balsa wood, reed and peacock feather are all taken from nature, and the performance of each kind cannot be guaranteed to be completely consistent because of the different parts taken. The "nano" bleached material is industrial synthesis, with uniform density and much greater stability than natural materials. The cost of mass industrial production is low.
4. Nano bleaching has high hardness and long service life.
Of course, in addition to materials, the choice of bleaching should also consider the production process, size, shape and various parameters of bleaching. It needs to be considered comprehensively according to the usage scenarios and purposes.
