Changzhou Jiayuan Chemical: UAN--The Cornerstone of High-Efficiency Nitrogen (Part 2)

Continuing from the previous articleIII. Downstream Application Practices: “1+1>2” Scenarios Through Matrix SynergyModel 1: The “Base Nitrogen Unit” in Fertigation. In drip or sprinkler irrigation systems on large farms, using UAN https://www.jy-chemical.com/urea-ammonium-nitrate-solution-product/() as the base nitrogen source, combined with water-soluble macro-element and secondary nutrient fertilizers, creates a precise and labor-saving nitrogen supply strategy. The nitrogen utilization rate can exceed 90%, which is 4-5 times that of conventional urea.Model 2: The “Synergistic Partner” in Functional Liquid Fertilizers. On cash crops like fruits, vegetables, and ornamentals, blending UAN with humic-acid-containing water-soluble fertilizers leverages a “nitrogen + soil conditioning” synergy. When combined with amino-acid-containing water-soluble fertilizers, it enhances crop stress resistance. Together, these combinations improve nutrient uptake efficiency and crop quality.Model 3: The “Flexible Component” for Customized Nutrition Plans. Targeting the specific nitrogen demands of different crops such as corn, potatoes, sugar beets, and cabbage, UAN serves as the nitrogen base for flexibly blending phosphorus, potassium, and micronutrients. For example, increasing the UAN ratio during corn’s jointing stage promotes stalk and leaf growth, while for sugar beets, pairing it with potash during the sugar accumulation stage increases the sucrose content. IV. The Value Loop of a Full-Series Product MatrixConstructing a full-series liquid fertilizer matrix represents a leap from "selling products" to “delivering yield outcomes”.For growers, a single supplier (e.g., Changzhou Jiayuan Chemical) offering a complete range of liquid fertilizers greatly simplifies procurement and blending decisions while reducing the risks associated with self-compounding. Using UAN and other specialty fertilizers within the matrix yields tangible benefits, including plump corn kernels, uniformly sized potato tubers, and dark green, robust vegetable foliage.For the industry, this model strongly accelerates the transition from solid to liquid fertilizers, from single-element to compound formulations, and from empirical to science-based fertilization. It reduces non-point source pollution and aligns with the national strategic direction for green, high-efficiency agricultural development.V. ConclusionThe true value of Urea Ammonium Nitrate solution (UAN) is being redefined within the “full-series liquid fertilizer matrix”. It is no longer an isolated nitrogen fertilizer variety but rather the core connector for an efficient, precise, and sustainable crop nutrition program.Modern agriculture does not need another “better single product”; it needs a “more complete solution”. Choosing a company like Changzhou Jiayuan Chemical, which possesses a sound liquid fertilizer matrix, stable product quality, and professional service capabilities, is a crucial step in translating the foundational potential of UAN into high yield and superior quality in the field. It is through the power of the matrix that we can deeply cultivate the soil and empower the future of agriculture.

Introduction: The “Nitrogen Efficiency” Challenge in Modern AgricultureNowadays, the Urea Ammonium Nitrate solution (UAN) (https://www.jy-chemical.com/urea-ammonium-nitrate-solution-product/), leveraging its unique properties, has become an indispensable “nitrogen source cornerstone” within high-efficiency liquid fertilizer systems. Companies like Changzhou Jiayuan Chemical Co., Ltd., by constructing a comprehensive liquid fertilizer matrix that covers UAN, macro-elements, secondary nutrients, humic acids, and amino acids, are providing modern agriculture with an upgraded pathway—moving from “single-element nitrogen supplementation” to “complete crop nutrition”. II. UAN: The “High-Efficiency Nitrogen Engine” Within the Liquid Fertilizer MatrixUAN’s role as the cornerstone of a liquid fertilizer system stems from two irreplaceable attributes.First, its exceptional compatibility and compounding ability. The UAN solution is clear, transparent, and free of impurities, allowing it to be stably miscible in any proportion with liquid phosphate fertilizers, potash fertilizers, secondary nutrients, humic acids, and amino acids. It functions not only as a standalone nitrogen fertilizer but also as an ideal base solution for formulating various functional liquid compound fertilizers.Second, its “three-nitrogen-in-one” release pattern. UAN simultaneously contains nitrate nitrogen (fast-acting, absorbed within hours), ammonium nitrogen (readily available, can be adsorbed by soil colloids), and amide nitrogen (slow-release, with an efficacy lasting several weeks). This scientifically formulated ratio of the three nitrogen forms provides both the "speed of action" to address acute nitrogen deficiency and the “duration of efficacy” to support sustained crop growth.Continued in the next chapter

The company's products are widely used in cutting-edge fields such as precision manufacturing cleaning, electronic heat dissipation and cooling, new energy, and semiconductor testing, and the company is committed to providing global customers with high-performance, low-environmental-impact fluorochemical solutions.Changzhou Jiayuan Chemical Co., Ltd. will continue to focus on the fluorochemical industry chain, promote the technological iteration and industrialization of green fluorosolvents, and contribute to the sustainable development of the industry.Octafluoropropane (C218/R218, chemical formula C₃F₈) is a colorless, non‑flammable, chemically stable perfluorinated compound. Its main applications are concentrated in three core industries: microelectronics, healthcare, and refrigeration. These applications are based on its chemical stability, non‑flammability, low toxicity, and specific physical properties (e.g., low boiling point, ultrasound contrast capability). The following sections provide a detailed description of its uses, end‑use industries, and the properties that enable them.1. Microelectronics Industry – Core use in chip manufacturingThe microelectronics industry is the largest consumer of octafluoropropane (https://www.jy-chemical.com/octafluoropropane-product/), accounting for more than 60% of global consumption. The key properties exploited are its chemical stability, low reactivity, and excellent plasma etching performance.1.1 Plasma etchantUse: Fine etching of integrated circuits (ICs) and semiconductor chips (including 5nm and below process nodes), especially for patterning materials such as silicon, silicon dioxide (SiO₂), and silicon nitride (Si₃N₄).Properties leveraged: High chemical inertness: in plasma state it reacts only with target materials (e.g., silicon) without corroding other chip structures, reducing process defects. The fluorine radicals (F·) generated during decomposition have moderate activity, providing controllable etch rates and enabling nanoscale precision for fine structures such as transistor gates and interconnect lines.1.2 Device surface cleaning agentUse: Removal of residual photoresist, metal contaminants (e.g., copper, aluminium), and polymer residues generated during chip manufacturing.Properties leveraged: Insoluble in water but volatile, so no additional drying step is needed after cleaning, avoiding moisture‑induced oxidation damage to chips. Low toxicity and no reaction with chip materials (e.g., metal electrodes, insulating layers), thus no new impurities are introduced.Application scenario: Precision cleaning processes in semiconductor assembly and testing (packaging). The most important medical use of octafluoropropane is as an intraocular gas tamponade after vitrectomy, mainly to assist retinal reattachment and promote macular hole healing. It utilises its chemical stability, good biocompatibility, and controllable absorption to create a stable environment for ocular tissue repair. A typical example is given below. 2. Medical applications – Adjuvant treatment for rhegmatogenous retinal detachment (RRD)Rhegmatogenous retinal detachment is a common ophthalmic emergency, where the neurosensory retina separates from the retinal pigment epithelium. Without timely treatment it can lead to blindness. Octafluoropropane plays a critical role as an “intraocular support” in such surgeries:Treatment principle: After vitrectomy to remove haemorrhage and proliferative membranes from the vitreous cavity, octafluoropropane gas at a concentration of approximately 18‑20% is injected into the eye. The gas expands inside the eye and tamponades the retinal break (especially those located in the mid‑peripheral or inferior retina), pressing the retina back against the pigment epithelium. At the same time it blocks the flow of subretinal fluid, giving the edges of the break time for cell proliferation and adhesion repair.Key advantages: Compared to air (intraocular residence time 1‑3 days), octafluoropropane has a longer absorption period (about 1‑2 weeks), providing longer‑lasting tamponade and reducing the risk of post‑operative redetachment. Its chemical stability means it does not react with ocular tissues (e.g., lens, iris), and the incidence of post‑operative complications (such as accelerated cataract progression) is lower than with other long‑acting gases (e.g., sulphur hexafluoride).Clinical operational details: After surgery, patients must maintain a specific head position (e.g., face‑down if the break is located inferiorly) to ensure that the gas continues to tamponade the break. The gas is gradually absorbed over 1‑2 weeks; after retinal reattachment, no second surgery is required to remove it.Continued in the next chapter

[ Jiayuan Rare Gas Monthly Review ] : Helium Rose Steadily in April, Expected to Fluctuate Upward in May (April 2026)

1. Market AnalysisThe monthly average price of bottled helium increased during this period. Geopolitical risks in the Middle East continued with no clear signs of improvement. Under Russia’s helium export controls, the supply shortage in China’s helium market intensified, leading to rapidly rising market prices, with transactions concentrated on the higher end. In April, bottled helium sales went relatively smoothly – channels actively took delivery in the first half of the month, while some channels began to release partial stock for profit in the second half, resulting in active market trading sentiment and an upward shift in the transaction center of gravity. The supply shortage persisted in the East China region, where channels were mostly reluctant to sell, making it somewhat difficult for downstream users to source product. The Southwest region also actively followed the price uptrend.The average price of both imported and domestic tube‑trailer high‑purity helium (https://www.jy-chemical.com/helium-product/) increased during this period. Due to uncertainty over the magnitude and duration of supply tightening, many players actively built inventories, and market supply gradually moved toward a tight situation. Imported helium led the price increase, with domestic helium actively following suit, leading to rapid price gains. According to statistics as of April 28, both the monthly average price of imported tube‑trailer high‑purity helium and that of domestic tube‑trailer high‑purity helium rose. Market trading sentiment was good, and enterprises mainly focused on active shipment.Xenon market prices were stable, but the transaction center of gravity moved downward, and the monthly average price declined, remaining flat month‑on‑month. The oversupply situation in the xenon market has not yet changed, with major producers holding high inventories, leading to an obvious decline in market prices.Krypton market prices were stable, but the transaction center of gravity moved downward. Downstream buying interest was mediocre, and enterprises mainly sold at low prices.Neon market prices were stable, but the transaction center of gravity moved downward. With ample channel inventory in the neon market, trading sentiment was relatively poor, and prices remained stable at low levels. 2. Market OutlookHelium market prices are expected to increase in May 2026. The impact of the Middle East conflict is expected to persist in May. Russian helium export controls are expected to see some easing. The market is anticipated to show a trend of initially falling and then rising. Domestic tube‑trailer helium prices are expected to rise. The overall supply tightening situation in the market is unlikely to improve. The anticipated easing of Russian controls in the short term can only alleviate the supply tightness to some extent, but it will hardly reverse the overall situation. As supply tightness evolves, the market is expected to return to its main upward trend.Xenon market prices are expected to decline further in May, due to weak downstream buying support.China krypton market prices still have room to decline in May, as enterprises face increasing delivery pressure amid high channel inventories.Neon market prices are expected to decline in May. In the short term, market trading sentiment is relatively weak.3.
