ABS surface static charge causes dust adsorption, demolding difficulties, electrostatic discharge during processing, transportation and use. Therefore, the ABS product requires a certain conductivity to prevent internal discharge, and even prevent electromagnetic interference of the external pairs of precision electronic components. Adding antistatic agents is the main method for preparing antistatic ABS. Other supportive evidence includes: exhalation flow peak differences> 20% change, at least two weeks. Three days a week, A ≥ 20% was sucked into the skin sugar or strong induced by salbutamol, and the peak of the subsequent treatment flow increased by> 20%, or the A ≥ 20% late contact trigger rear initiator was reduced by> 20% D. The test breathing flow peak is more likely to change than respiratory measurement, but it is not recommended for regular diagnosis. This approach may be useful for daily monitoring and new drugs in patients with medium weight diseases. It may also help guide the treatment of acute episodes. Domestic photoresist raw materials production is still in its infancy, showing less product type and small production scale, but is achieved from zero, and gradually develops to the entire category. Strong material can cover photoresist resins, monomers and photoinitiators, long-term purchase of new materials, and invest in micro-core materials also completed photoinitiators, resins and monomer layouts. Some photoresist manufacturers such as Xuzhou Bo Kang, Jacques Technology, Tongcheng new materials have some of the production capacity of some raw materials. Ability to achieve self-sufficient photoresist production companies will receive lower production costs and master more autonomy. In addition, the amount of the initiator can also affect the curing speed of the UVLED, and the amount of the initiator is generally controlled at about 3%, since the ultraviolet radiation is absorbed if the initiator is excessively, greatly reduces the ultraviolet radiation at the bottom of the coating film to reduce the curing speed. As described above, from the third quarter, under the gradual recovery of the domestic market and the company's flexible sales strategy and price strategy promotion, the company's product sales have grown steadily. Just as in this contract, the company is seen from historical data, the company's main product prices have fallen to historical low. With the stability of the global epidemic and the recovery of global market demand, the company's products are expected to stop falling and recovery. The operation income in the fourth quarter of 2020 increased. In the first quarter of 2021, the company's photoinitiator sales reached 5 tons, a year-on-year growth, and the operating income was 311,387 yuan, a year-on-year growth. In summary, the decline in the company's operating income is not sustainable. The photoresist industry chain is wide, and the upstream raw materials are an important part of the photoresist industry. The quality of the raw materials determines the quality of the photoresist products. The main raw materials include resins, photoinitiators, solvents and monomers; in the middle of various photoresist, mainly divided into PCB photoresist, LCD photoresist, semiconductor photoresist; downstream as the application field, photoresist main use The manufacturing printed circuit board, a flat panel display, semiconductor, and the like. The photoresist industry chain is high, including raw material barriers, formula barriers, equipment barriers and downstream certification barriers. After the drip, H, partially added a mixture of initiator and solvent at a certain temperature. Then, in a certain temperature ~ h, the entire reaction is protected. When the monomer conversion is ≥%, it is discharged. The thermoset resin of the reaction mechanism is widely used in the coating.2-Benzyl-2-(dimethylamino)-4-morpholinyl phenylbutanone 2-Dimethylamino-2-benzyl-1-[4-(4-morpholinyl)phenyl]-1-butanone 2-Phenylbenzyl-2-dimethylamine-1-(4-morpholinebenzylphenyl)butanone 2-Benzyl-2-dimethylamino-4-morpholine 2-Benzyl-2-(dimethylamino)-1-[4-(morpholino)phenyl]-1-butanone Photoinitiator 369 2-Benzyl-2-(dimethylamino)-1-[4-(4-morpholinyl)phenyl]-1-butanone Photoinitiator 369 PI-369 manufacturer  Compared with other resins, it has the advantages of color, shallow, light, weather resistance, chemical, solvent resistance, high gloss, widely used in industrial fields such as automobile home appliances. The preparation of the resin is mainly based on the polymerization, and the entire reaction includes the growth and termination of the chain. In the synthesis of the resin, the use and addition of the glass-transmissive temperature solvent initiator and the chain transfer agent is an important factor affecting the resin. In addition, the morning photochemical research institute also prepared a 79-3 modified amine oxygen curing agent in an acrylonitrile and an epoxy compound as a substantive material. BPO as an initiator system monomer transformation rate, BPO decomposition product causes disadvantages of acid value, foaming time, and foam intensity of graft products. I am very clear in my heart, there is not enough nutritional guarantee, the treatment of cancer is difficult to achieve, because the treatment is long, the impact on important organs is particularly high: inhibiting the bone marrow can cause white blood cell reduction, easy to infect; destroy the gastric mucosa, causing nausea and vomiting Destroy the intestinal mucosa, resulting in diarrhea; due to the use of stopping agent, bone deposit, joint pain, etc. So each cancer patient must pass through the food level. If you can't eat hot food, you can eat cold food. If you can't eat once, you can eat five or seven meals. No matter what method you use, you have to eat. Under the driving of this news, the semiconductor plates rose, and the overall value of the semiconductor plate in early market value exceeded 10 billion yuan, of which sub-industrial chain photoresist performance is clear. Entrepreneurship stocks have a closed daily limit and become one of the only daily limitations of the GEM; the opening is less than 10%.Photoinitiator 369 supplier  In April this year, the company expressed on the interactive platform of the interactive platform. The company introduced acrylic resin, Kisco photoinitiator, DKC photosensitizer, color paste and other products from South Korea, mainly for LCDs. -TFT is photoresist, chip and semiconductor industries I / G / H photoresist.
