• Paste Bag Filter Bags Phenomenon
    Sep 02, 2021 Paste Bag Filter Bags Phenomenon
    "Paste Bag Filter Bags" means that during the long-term operation or outage of the dust-removing cloth bag, in the working conditions with high humidity or oily substances contacting the filter material, the dust is condensed, adhered or condensed on the filter surface of the dust-removing cloth bag or inside the filter material. The shell cannot be effectively removed by the online dust removal system, resulting in a phenomenon that the operating resistance is greatly increased. It mainly includes condensation paste bag filter bags, cohesive paste bag filter bags and structural paste bag filter bags. Condensation paste bag filter bag mainly refers to liquid water will be formed when the operating temperature is lower than the dew point. The liquid water and dust will mix and gather on the surface of the filter bag to form a paste bag. The adhesive paste bag is mainly due to the relatively high adhesion of dust, which adheres to the surface of the fiber, and the online dust removal system cannot remove it. Structural paste bags refer to all paste bags caused by dust collector design and related component structure and improper operation. Either way, to solve the problem of "sticking bag", it is necessary to analyze the working conditions of flue gas, dust collector, filter material, operation control and other related factors, so as to understand the real inducing factors of the sticking bag, so as to avoid and solve the problem.

    2. The profit quality is high-quality, and the valuation advantage under high R&D may welcome Davis to double-click High-quality corporate profits can lay a good asset foundation for the future development of the company. The performance of Yuanchen Technology’s financial report this time also makes people more confident in its future growth. The decline in Yuanchen Technology's gross profit margin is only a short-term impact, and the predictability will be restored in the later period and it can open up the upward space again. According to the interim report, the company's 2021 half-year operating cost was 150 million, a year-on-year increase of 63.1%, which was higher than the growth rate of operating income of 26.9%, resulting in a 14.9% year-on-year decrease in gross profit margin. We can find the reason from the expense side: management expenses increased by 41% compared with the previous quarter. As a company listed on the Sci-tech Innovation Board at the end of March, in addition to the increase in employee compensation, a large part of it is the increase in listing-related expenses. Sales expenses only increased by 3.66%, but in the past three years, Yuanchen Technology has continued to grow in this indicator, and it has even doubled from 2019 to 2017. These data directly demonstrate the above two growth points of Yuanchen Technology, namely: non-electric business and third-party testing, and the expenses incurred in the current vigorous expansion, such as sales team and promotion expenses. In this interim report, strategic cooperation has been reached with many well-known brands. With the development of high value-added products in the non-electricity market strategy, the industry itself has technical barriers and qualification barriers enough to form a long-term and stable relationship with customers in the later period, so the short-term increase in sales expenses is understandable for the development of this company . On the other hand, R&D investment continues to increase. According to the interim report, Yuanchen Technology's R&D investment accounted for 6.39% of revenue, which was an increase of 0.31 percentage points from 6.08% in the previous quarter. Moreover, R&D investment has continued to grow in the past five years, which has ensured the competitiveness of enterprises. According to the data, from 2017 to 2020, the company's R&D expenses reached 13.484 million yuan, 16.398 million yuan, 19.0582 million yuan, and 25,429,100 yuan, respectively, accounting for 5.05%, 5.06%, 5.25% and 5.54% of operating income in the same period. Yuanchen Technology has a very mature research and development model. It has established the Science and Technology Research Institute and formed a standardized project-based research and development system with independent research and development as the mainstay and cooperative research and development as the supplement. After a strict feasibility study by the Science and Technology...

    In the secondary market, there are only two kinds of money that can be made: 1. The money brought by the growth of the enterprise; 2. The money made from the counterparty through the game (the money transferred from the wealth of the competitor). The so-called growth money refers to the rise in stock prices due to the growth of corporate performance when the valuation level has not undergone drastic changes. As Charlie Munger said: "In the long run, the annualized rate of return of stocks is roughly the same as the growth rate of its net profit margin, and it is difficult to exceed the latter's growth rate." In the short-term market, there are always deviations. On the one hand, most investment banks can cover limited stocks. Therefore, many small and medium-sized stocks without analyst coverage may be underestimated due to market neglect. On the other hand, the growth forecast behind this bias is too low, and it can also be an innate bias, such as the environmental protection sector. On August 12, Yuanchen Technology, a science and technology board stock, released its semi-annual financial report. During the reporting period: the company achieved operating income of 227 million yuan, a year-on-year increase of 26.91%; net profit attributable to shareholders of listed companies was 28.862 million yuan, a year-on-year increase of 293.78% ; The net profit attributable to shareholders of the listed company after deducting non-recurring gains and losses was 25.065.1 million yuan, a year-on-year increase of 418.09%; basic earnings per share were 0.21 yuan. This is an extremely ideal report card. Not only did the half-year net profit attributable to the parent nearly tripled year-on-year, the growth rate of revenue and net profit in the second quarter of the year was substantially greater than that of the first quarter of the current period or the same period of last year. Growth. Shows the quality of the company's development. In fact, this semi-annual financial report is a microcosm of Yuanchen Technology’s steady performance during its growth. Looking back on the past five years, it is driven by the pragmatic main business, vigorously developing the non-electricity market, and actively deploying the upstream and downstream industrial chains. , Yuanchen Technology's revenue and net profit continued to grow, drawing a steady growth curve. Growth has always been the eternal proposition of enterprise development. Looking through the financial report of Yuanchen Technology and the dismantling of its core capabilities are not only the secret of Yuanchen Technology's continuous growth in the past, but also the key to understanding the company's future growth. 1. Consolidate the main business to seize the non-electricity market, and the integrated and in-depth layout shows advantages Yuanchen Technology is focused on the research and development, production, sales and service of filter materials and flue gas purification series of environmentally friendly p...

  • Yuanchen Technology Sharing-Microemulsion Dispersion Theory
    Aug 20, 2021 Yuanchen Technology Sharing-Microemulsion Dispersion Theory
    Oil and water are not mutually soluble, but can form an opaque emulsion dispersion system, which is the early "microemulsion". The microemulsion method has been widely used in materials science, pharmacy and engineering. Its essence refers to the use of two immiscible solvents to form a uniform emulsion under the action of surfactants. The microemulsion is thermodynamically stable, isotropic, transparent or translucent in appearance, and the diameter of the dispersed phase is about 1-100 nm. In terms of functional filter materials, the microemulsion method can also be applied to the development of functional filter materials. The microemulsion method can prepare water-insoluble nanoparticles into a uniform and stable dispersion. The water-insoluble nanoparticles can be loaded on the surface of the fiber by the way of emulsion dipping, making the filter material waterproof, oil-proof, and strong. Integrated function with catalytic dust removal. The key of the microemulsion method is to make each droplet of the aqueous solution containing the precursor be surrounded by a continuous oil phase (each droplet containing the precursor is surrounded by a continuous water phase), and the precursor is insoluble in the oil phase emulsion. That is to form a water-in-oil (W/O) emulsion or an oil-in-water (O/W) emulsion. The schematic diagram is shown in the following figure: Microemulsions are usually composed of surfactants, co-surfactants, solvents and water (or aqueous solutions). In this system, two incompatible continuous media are divided into tiny spaces by surfactant amphiphilic molecules to form a micro-reactor whose size can be controlled in the nanometer range, and the reactants react in the system to form solid particles. Because the microemulsion can accurately control the particle size and stability of the nanomaterials, it limits the nucleation, growth, coalescence, and agglomeration of the nanoparticle. The resulting nanoparticle is wrapped with a layer of surfactant and has a certain degree of Condensed matter structure. The solid phase is separated from the emulsion, so that the processes of nucleation, growth, coalescence, and agglomeration can be confined to a tiny spherical droplet, which can form spherical particles and avoid further agglomeration between the particles. Commonly used surfactants are: double-chain ionic surfactants, such as dioctyl sodium sulfonate (AOT); anionic surfactants, such as sodium dodecyl sulfonate (SDS), dodecyl benzene Sodium sulfonate (DBS); cationic surfactants, such as cetyltrimethylammonium bromide (CTAB); non-ionic surfactants, such as TritonX series (polyoxyethylene ethers), etc. Commonly used solvents are non-polar solvents, such as alkanes or cycloalkanes. The mechanism of surfactant action is as follows: Since the first public report of microemulsion for more than 70 years, the basic theory of microemulsion has been continuously developed and perfected day by day. Due to its good solubilization and st...

  • Hot spot sharing-To achieve
    Aug 19, 2021 Hot spot sharing-To achieve "carbon peak and carbon neutrality", we must avoid misunderstandings
    The “3060 target” of carbon peak and carbon neutrality has aroused great repercussions after it was put forward. This is an active choice made by China when facing future challenges, which means that China’s economy will grow in the future and develop in the future. There will be some huge changes and some brand new changes on the path.  Achieving carbon neutrality itself has strong strategic significance. On the one hand, it is the transformation of economic growth mode. On the other hand, it also means that we can communicate with the world on a wider range of topics. This is also our participation in building a community with a shared future for mankind. A concrete move. The Chinese government proposed that carbon peaks in 2030 and carbon neutrality in 2060 will be less than half a year later. "Carbon neutrality" has become a key word that Chinese companies must mention. The fastest response is undoubtedly the central enterprises. State Power Investment, Baowu Steel, Datang, and Huadian have expressed their efforts to achieve carbon peaks in advance. Financial companies followed closely behind. In public speeches in the past few months, Industrial and Commercial Bank of China, China Construction Bank, Industrial Bank, Central Bank, and Agricultural Bank have announced that they will underwrite the first batch of "carbon neutral bonds." At the same time, Internet giants have also joined the carbon neutrality race. Tencent announced the launch of its carbon neutral target plan on January 12 this year. On March 12, Ant Group locked in to achieve its net zero emission target by 2030. From traditional high-carbon industries such as energy and steel to emerging technology industries with sharp increase in energy consumption and increasing carbon emissions, new companies have joined the "carbon neutral" team. This is to ensure that China achieves the "double carbon goal" The key force. In addition, there has been a lot of discussion after the goal of carbon peaking and carbon neutrality "3060 target" was put forward. Everyone generally feels that the pressure is great, the task is heavy, and the time is short. At the peak time, what level will our carbon emissions be at? The prevailing view now is that China’s net carbon dioxide emissions should exceed 10 billion tons when the carbon peaks, and the more common figure should be 10.8 billion tons or 11 billion tons. It’s only 30 years for us from peaking carbon to carbon neutrality, and it’s only 30 years from 11 billion tons or 10.8 billion tons to zero. This is only 30 years, while EU countries peaked in carbon in the last century. It has been more than 70 years, and the United States has more than 45 years. Under this situation, the task is indeed too arduous, which means that all-round changes in the industrial structure and the growth mode of the energy structure are required. However, in addition to praising companies for their quick response, we also see that companies currently generally l...
