Calcium carbide powder; Powdered calcium carbide: It can make the chemical reaction more complete and rapid. Instant response, suitable for laboratories and precision processing Size:  0-0.5mm Product Advantages:  High gas yield, High purity, Stable performance, and Safety in use Application Physical and chemical properties (1) Highly reactive: The powder state maximizes the contact area of calcium carbide particles. When reacting with water, the rate of releasing acetylene (C₂H₂) per unit time is much higher than that of bulk calcium carbide (up to 3- 5 times that of ordinary calcium carbide). It is suitable for scenarios that require instantaneous high flow of acetylene (such as precision combustion and rapid synthesis reactions). (2) Rapid and complete reaction: Traditional bulk calcium carbide forms a calcium hydroxide (Ca(OH)₂) coating after surface reaction, which hinders the internal reaction. The utilization rate is usually only 70-85%. Powdered calcium carbide has tiny particles and almost 100% reaction, with no core unreacted residue, which significantly reduces the amount of waste residue. (3) Suspension and dispersibility: In specific solvents (such as mineral oil or organic media), powdered calcium carbide can be evenly dispersed and used in reaction systems with controlled slow release of acetylene. It can also be transported by air flow to achieve automatic feeding. Unique industrial application advantages (1) Precision chemicals and laboratories Gas chromatography carrier gas: When high-purity acetylene is required, powdered calcium carbide can react quickly and filter impurities, which is more flexible than cylinder gas supply. Nanomaterial synthesis:As a carbon source, it participates in the chemical vapor deposition (CVD) process of carbon nanotubes (CNT) or graphene. Due to its fast reaction rate, the release of carbon atoms can be precisely controlled. (2) Metallurgical industry High-efficiency desulfurizer: In steel smelting, powdered calcium carbide can instantly combine with sulfur in molten metal (generating CaS) to improve desulfurization efficiency Alloy additive: Through the jet injection method, it directly participates in the regulation of carbon elements in the metal liquid (such as high-carbon steel production). (3) Pharmaceutical and pesticide synthesis Highly active intermediates: When synthesizing vitamin A and alkyne drugs, powdered calcium carbide can quickly provide acetylene groups (-C≡CH), shortening the reaction time.

Microcrystalline wax is a high-melting-point, fine-crystalline hydrocarbon mixture produced from petroleum distillation residues through deep refining and deoiling. Its key characteristics lie in its flexibility, adhesion, and thermal stability, which are significantly superior to those of ordinary paraffin.‌‌ Oil Content Control: High-quality industrial-grade products typically have an oil content below 2%. Lower oil content results in higher hardness and minimal shrinkage, while slightly higher oil content provides better flexibility and adhesion. Color and Luster: It typically appears as milky white to pale yellow granules or lumps with a light color. It develops a luster when rubbed, which is advantageous for the production of light-colored products. ‌Solubility and Compatibility‌: Insoluble in water and cold ethanol, but soluble in organic solvents such as benzene and chloroform; miscible with various mineral and vegetable waxes, and capable of raising the melting point of wax blends.‌‌

Microcrystalline wax is commonly used as a raw material for yarn waxing, which is one of its key applications in the textile industry. Reducing friction as a lubricant: This is its most fundamental function. Microcrystalline wax forms a lubricating film on the yarn surface, effectively reducing friction between the yarn and textile machinery, thereby lowering yarn breakage rates and improving production efficiency. At the same time, this protective film also enhances the yarn’s abrasion resistance, enabling it to withstand the rigors of high-speed spinning and weaving processes. Good flexibility and high elongation: When subjected to stress, microcrystalline wax tends to flow plastically rather than fracture brittle, which prevents it from peeling off the yarn surface after application and ensures long-lasting lubrication. High molecular weight and strong adhesion: It has a higher molecular weight than paraffin wax, providing better adhesion to the yarn and forming a more durable coating.

1. Allulose as a new type of sweetener, the advantages compared with other similar sweeteners as following: A. In taste, Allulose is the closest to sucrose, about 70% sweetness of sucrose, but its calories are far lower than sucrose, nearly zero calories (allulose calorie value per gram is about 0.2-0.4 calories, 3.89 calories per gram of sucrose) for obesity and diabetes patients, its a ideal substitute for sucrose. It has the characteristics of safety, soft and delicate taste, mild sweetness, no bad taste during use, and no limit on the amount of addition; B, Allulose is one of the few sugar substitutes that can produce a Maillard reaction, so it can be used in baked food fields that require high-temperature reactions. C. In terms of health, Allulose hardly metabolizes and provides no heat after being absorbed by the intestine. At the same time, Allulose acts on the receptors of these brain regions through the release of GLP-1 (glucagon- like peptide-1), which ultimately leads to decreased appetite and enhanced satiation, and can also reduce the absorption rate of glucose, fructose and other sugars in the small intestine. Thereby reducing the accumulation of body fat. D. Allulose is a weak inhibitor of α-glucosidase, α-amylase, maltase and sucrase, which can inhibit the metabolism of starch and disaccharides in the gastrointestinal tract, and inhibit the rise of blood sugar by protecting pancreatic beta cells, with potential anti-hyperglycemia effect. Therefore, Allulose can help increase insulin sensitivity and reduce the risk of type 2 diabetes. E, in addition, since it does not lower the PH in the mouth and does not increase the risk of dental caries, the use of allulose can reduce dental caries. 2. Allulose is mainly used in table sugar, beverages, candy, milk, energy bars, ice cream and other products, about 55% for food, 37% for drinks, and a small part for medicine. 3. Due to the advantages and special functions of Allulose, which is evaluated as the most potential sucrose substitute by the US Food Navigation network, aloxulose is becoming one of the preferred sweeteners for food and beverage NPD in the United States at a leap speed, and the industry predicts that Allulose will become the next popular natural sweetener sweeping the world after stevia and erythritol. With the increasing demand for sugar-free beverages in the market, Allulose may become a tipping point for beverage manufacturers to upgrade their iterative products. 4. For beverage customers, they are also very concerned about the acid-heat stability. The acid-heat stability data of Allulose compared with sucrose.
