With the continuous development of the electronic defense industry, the market demand for high purity silane is increasing. In order to improve market competitiveness, seize favorable status, the company started construction of high-purity silane second phase project in December 2015. This project is based on successful annual output of 600T high purity silane production technology, expanding production scale, and building an annual production of 3000T high purity silane production line.
1. Different active ingredients: the active ingredient of the paste is an alternative triethoxysilane, the liquid is three B m2, and the liquid reflows 600 / m2. A 3. The color is different: the paste is white, the liquid colorless is transparent. The silane impregnated paint paste or liquid is selected according to the specific conditions of the project. The difference between the silane impregnation with conventional concrete protective coatings is as follows: 1. The silane impregnation is very different from the ordinary concrete protective coating. Silane impregnation has permeability, non-film resistance, waterproof, and gas permeability; normal protective coatings mainly by shielding protection.
China Steel Structure Industry Chain Trading Platform explains in detail the knowledge and details of HBZWXX02 Heyuan Equipment Steel Structure Company. The steel structure is a structure consisting of steel structural materials and is one of the first building structural types. The structure is first consisting of beam steel, steel column, steel truss, steel plate, steel plate, and use silanization, pure manganese phosphating, drying and drying, galvanized and other dermal rust processes. Welding, bolts or rivets are connected between the components. Due to its weight, consumption, consumption, widely used in large factories, venues, super high-rise buildings and other fields.
The effect of material itself, core indicator - an effective product content: liquid requirements>
bis(trimethylsilyl)trifluoroacetamide factory N,O-bis(trimethylsilyl)trifluoroacetamide supplier BSTFA manufacturer paste requirements> 80%. Many material suppliers are now significant below this standard, and the most direct impact is that durability does not meet the design requirements. Therefore, when choosing a good silane impregnated coating, be sure to pay attention to the above indicators. A good silane impregnated coating is a guarantee of the anti-corrosion effect.
Silane methyl acryloyloxysilane or the like. The filler can be processed in advance or directly to the resin. It can improve the dispersibility and adhesion of the filler in the resin, improve process performance, and improve the mechanical electrical and weather resistance of filler plastics including rubber. It enhances their bond strength, water resistance and weather resistance. Silicon coupling agents can often solve some problems that some materials have not bonded. The principle of the silane coupling agent as a tackifier is that it has two groups, and one group can be bonded to the viscous skeleton material, and the other group can be combined with a polymeric material or a binder to the bonding interface. To form a higher chemical bond, greatly increase the bond strength. The application of a silane coupling agent generally has three methods: one is a surface treatment agent as a skeleton material, and the other is to add a binder, and the other is to directly add a polymeric material. Give full play to its efficiency and reduce costs.
According to reports, Poly Qixin particle silicon was produced using a protoxilicon fluid bed method, and the raw material trichloroside disproducts the silane. Silane is decomposed in fluidized bed to form a particulate polysilicon, and the one-way conversion can reach 99%, reducing exhaust gas recovery and distillation, and the reaction temperature is only 60% of Siemens, which can be continuously produced, energy consumption and cost.
In the future, in the context of safe environmental protection requirements. In the context of continuous advancement of supply side reform, silane companies will develop towards the trend of China, and regionalization. With the growth and maturity of emerging markets such as new energy vehicles, composite materials, surface treatment, it is expected that by 2023, China's total production will reach 390,000 tons. Compared with 2019, the average annual growth rate of composite materials is.
Silane and oxidant. oxygen. Alkali. The halogen reaction is very intense, and there is no purge gas bottle in the nitrogen purge process, especially the VMB area. Once inverted, it will cause dramatic explosion. In the 1980s, the United States had a case in which smile poured into the silane gas bottle caused by the explosion. At the same time, pay attention to the quality of the purge gas, and the oxygen content control is also a very important critical node. In order to ensure the gas quality, the silane recommends a purge system separately, and the purge system is equipped with a purification device to ensure that the oxygen content in the purge gas is low enough.
The drill core sampling test, the test results can be sprayed in a large area of the creamilage in a large area of the structure. (b) Is not conducive to harmful substances and contaminants such as dust, oil and oils such as silane. (c) When concrete uses release agents or conservation agents, the effect of release agents or maintenance agents on silane impregnation should be determined by spray test, otherwise the silane dip should be sufficient. Concrete antiseptic silane impregnation is a small molecular structure, which can penetrate the surface of the gel, penetrate into the concrete, exposed to acidic or alkaline.
Li Jiming [4] is based on silane sealing polyurethane prepolymer prepared a single component moisture-cured silane sealed polyurethane sealant, examining the effects of additives and fillers on the properties and drying time on the properties of the formulation, study The improvement of its storage stability is improved.
