(Summary description)Photoinitiator is an important part of the composition of light-curing adhesives, because UV glue must be cured under the irradiation of ultraviolet light. Once the photoinitiator is lacking, the irradiation energy cannot be used, and the light irradiation intensity cannot be reached. , So the photoinitiator is particularly important for the shadowless glue.
　　 The photoinitiator in the uv glue should pay attention to its absorption spectrum to match the emission spectrum of the light source. At the same time, for better reaction, a composite photoinitiator can be used. Only by using a good photoinitiator, the curing of UV glue can achieve good results.

Photoinitiator supply 2021 / 06 / 07
The company normally supplies photoinitiators TPO and TPO-L at reasonable prices and the quality has reached export standards. Welcome to discuss business!
Water treatment agents are agents for purifying water quality 2018 / 09 / 30
The water treatment industry is a cutting-edge industry that protects people's surrounding water circulation, reduces or treats polluted water quality. At the same time, there is great competition in the water treatment chemicals market. Water treatment is now not only the introduction and use of various water treatment special equipment, but also plays a big role in water treatment chemicals. Water treatment chemicals are now and in the future. The necessary chemicals for sewage treatment, the prospects are very optimistic. Water treatment chemicals are specially used for sewage clarification. Everyone knows that there are many processes for water quality treatment. Therefore, the classification of water treatment chemicals is very wide, including organic water treatment and inorganic water treatment chemicals, which are dedicated to cleaning scales. Of descaling agent. These different chemicals all play a very important role in water treatment and can be said to be the most important treatment link in water treatment. Water treatment chemicals are not only effective in the precipitation of sewage flocculants, but also in the treatment of sludge dewatering. They are also very effective in the treatment of industrial wastewater. It is inevitable that some polluted wastewater will be produced in the industry, and water treatment chemicals can treat these wastewater, so that the sewage can be purified again and recycled again, saving water resources and protecting the water environment. Hao Nuo water treatment chemicals manufacturers are willing to work with environmentalists to maintain the cleanness of human water resources.
Water treatment agent application landscape water 2018 / 09 / 30
There are many kinds of landscape water treatment technologies, which are mainly divided into physical, chemical and microbial treatment technologies. Physical technology such as water change: dilute the concentration of impurities in the water by diversion and change of water, thereby reducing the concentration of impurities. However, a large amount of clean water needs to be replaced. Today, when water resources are quite scarce, it is necessary to reduce the waste of precious water resources. Chemical method (addition of bactericidal and algaecide) water body under the sunlight will cause the algae in the water to multiply and cover the entire water surface, which not only affects the beauty of the water body, but also blocks the sunlight, making many underwater plants unable to carry out Photosynthesis releases oxygen and chemically changes the pollutants in the water, which causes the water quality to deteriorate, emits an unpleasant stench, and the water turns black. So add a chemical algicide to kill the algae. Over time, drug-resistant algae will appear in the water, the effectiveness of the algicide will gradually decrease, the interval of dosing will be shorter and shorter, and the amount of dosing will be more and more, the varieties of the algicide should be changed frequently, right Environmental pollution is also increasing, and this pollution will affect our next generation. But at the same time, the chemical method equipment cost is relatively high (circulation equipment, dosing device), and the operating cost is relatively high (power consumption, medicament cost). Although the effect is obvious, the maintenance time is short, the operation is relatively easy, and special management is required. Microbial treatment methods (ecological water treatment technology) There are many kinds of bacteria in the biological kingdom, and they all have quite complex physiological characteristics. In aquatic ecology, microorganisms that are decomposers can remove pollutants (including organic matter, certain heavy metals, etc.) in the water. Etc.) to be decomposed and absorbed into substances that can be used by other organisms. At the same time, it can reduce or eliminate the toxicity of certain toxic substances. It can convert the residual branches and leaves of aquatic plants into organic fertilizer and increase the soil’s Organic matter, and improve the soil, improve the soil aggregate structure and physical properties, increase the environmental capacity of the water body, enhance the self-purification ability of the water body, and reduce soil erosion and inhibit the growth of plant pathogens. Therefore, the use of water treatment agent technology for water treatment is highly efficient and environmentally friendly. It provides favorable conditions for growth, biochemical effects are formed, and the biochemical effects of microorganisms effectively remove organic and inorganic pollutants, which provide the next stage of water treatment. Favorable conditions.
Principles of using photoinitiators 2018 / 09 / 30
1. The photoinitiator is used in conjunction with the amine accelerator EDAB. 2. Small smell, non-toxic, no environmental pollution. 3. It is cheap and easy to obtain, with low cost. 4. Choose a photoinitiator with appropriate activity according to the type of prepolymer and monomer. 5. It has good solubility and reactivity, low dosage and high initiation efficiency. 6. It must have a certain degree of thermal stability, it will not decompose below 85℃, and it should have long-term storage stability. 7. It is best to use several photoinitiators in combination, which can initiate curing in different wavelength ranges, which is faster than a single photoinitiator. The above content is the overview, mechanism of action, performance requirements, common types, characteristics and principles of use of photoinitiators shared by the editor. Photoinitiator is one of the indispensable components of free radical ultraviolet light curing reaction system. Its type and amount have a great influence on the light curing behavior of the system, and play a decisive role in the sensitivity of the light curing system.
