AKD wax introduction Chemical name: Alkyl Ketene Dimer Alias: AKD wax AKD powder is also called AKD wax. Chemical name is Alkyl ketene dimer. CAS registration number is 144245-85-2. Appearance is pale yellow flake or granular solid. It is produced by fatty acid (C16), via acylation and dehydrochlorination to become AKD wax. AKD wax is mainly used for papermaking neutral sizing agent. R or R' in the above structural formula is the alkyl group, and a series of alkyl ketene dimers can be obtained through modifying different alkyl groups. Octodecane and cetane are applicable to the papermaking neutral sizing agent. Alkyl ketene dimer is a white-to-yellow solid with the melting point of about 47 ~ 51 , which can be soluble in ethyl alcohol, benzene, chloroform and other organic solvents. The reactive group of alkyl ketene dimer-ketone group has high activity and makes esterification reaction with the hydroxyl in cellulose. Product Application AKD wax can be made into AKD emulsion applied as in sizing agent in the papermaking production. AKD wax is emulsified by the cationic emulsifier, and melted AKD wax and emulsifier undergo high-speed shearing and high pressure homogenization to form the liquid AKD sizing agent after cooled. In the papermaking process, application of AKD sizing agent gives the fluid resistance to paper and paperboard to prevent or delay the penetration and diffusion of some liquids on paper fibers, thus satisfying people's requirements on the processing and use of paper products. AKD contains hydrophobic group and hydrophilic group, which are well distributed in the sizing process to transfer to locate the process of bonding with cellulose. AKD emulsion particles stay between negatively charged paper fibers since they carry with positive charge by virtue of cationic starch and PAM and other retention agents; In the pressing and drying process of the paper machine, these globular AKD particles are easily expanded and distributed on the surface of fibers due to the lower melting point to form a homogeneous cover film; When paper is dried and stored for a period, the active group (lactone ring) on AKD molecule makes the esterification reaction with the hydroxyl on fibers under certain conditions to be binding on fibers in the form of fixed covalent bonds. Hydrophobic long-chain alkyls transfer to the paper surface in order to give the penetration resistance to paper.
AKD wax(Alkyl Ketene Dimer, Simplified: AKD) is a neutral sizing agent, which can directly react with fiber. AKD wax produced by Shandong Tiancheng Chemical Co., Ltd, With high content and low acid value, is more efficient a sizing agent. AKD WAX Advantage 1. Higher purity 2. Lower acid value PRODUCT DESCRIPTION AKD WAX Specification Assay %: 90 min Iodine Number gI2/100g: 45 min Acid Value cPs/25â??: 5.0 max Melting Point: 47 min Appearance: Pale yellow granule Packaging: 25kg/bag Shelf life: 6 months

Buffer solution is a type of buffer system dedicated to life science research. In biochemical experiments, buffer solution plays an indispensable role. It can resist the influence of a small amount of strong acid and alkali from the outside, and maintain the system closest to the physiological environment. pH value. Both HEPES and PIPES buffers are commonly used buffers in biological experiments. The pH buffer range of HEPES is 6.8-8.2. It is a zwitterionic biological buffer. It is soluble in water and does not form stable complexes with metal ions. In most cases, it will not interfere with biochemical processes and can be widely used in a variety of Biochemical reactions and used as buffer reagents in certain cell culture media. HEPES is often used in the cell culture medium of various types of organisms; in protein research, PIPES is often used as the component and eluent of the binding buffer in cation exchange chromatography; in DNA research, PIPES is used as calcium phosphate and DNA The buffer for the precipitation formation system, AFM and the buffer for electroporation experiments. In addition, HEPES interferes with the reaction between DNA and restriction enzymes, and is not suitable for Lowry's method to determine protein content. HEPES buffer is often used in the research of organelles and highly variable, pH-sensitive proteins and enzymes, as well as in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. It is a hydrogen ion buffer that can control a constant pH range for a long time. The final concentration is 10-50mmol/L, and the buffering capacity can be achieved when the culture medium contains 20mmol/L HEPES. The pH buffer range of PIPES is 6.1-7.5, insoluble in water, soluble in NaOH aqueous solution. PIPES is different from buffers containing two (2-hydroxyethyl) amino groups (such as Bis-tris, Bicine), and can not form stable complexes with most metal ions. It is suitable for buffers in solution systems containing metal ions. According to existing research results, PIPES can be used to purify tubulin using phosphocellulose chromatography, to purify recombinant GTP-binding proteins ARF1 and ARF2 by gel filtration, and to use as a buffer to crystallize transketolase from E. coli. In addition, because PIPES can form free radicals, it is not suitable for redox systems. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because PIPES has a relatively large ionic strength and its pKa value is concentration-dependent. We must learn to distinguish between the similarities and differences in these reagents, so as to better promote the development and production of our different products. Desheng unanimously adheres to this kind of subtle difference, so that it can continue to develop and produce better products.

HS Code : 28151110 Brief Description: ; Caustic soda (sodium hydroxide) is a versatile alkali. It is a white solid ionic compound consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Main Uses/ Industry : " Caustic soda reacts with bauxite to dissolve aluminium-bearing minerals in the ore so that insoluble impurities can be separated. The purified alumina is then used to produce aluminium. Caustic soda is commonly used as a reagent in chemical reactions. Caustic soda is used in the saponification reaction to manufacture soap. In detergents, it is a part of the process of neutralisation of LAB. Caustic soda solution is used in the exploration, production and processing of petroleum and natural gas. It is also used as an adsorbent for carbon dioxide in light petroleum fractions; a treatment step in removal of various sulphur compounds. Caustic soda solution is used in the pulping and bleaching process and de-inking of waste paper. Caustic soda forms an important input in the steel industry. It is used to clean steel. Caustic soda solution is used to process cotton and dye synthetic fibres such as nylon and polyester. Mercerising of fibre with sodium and hydroxide solution provides greater tensional strength and consistent lustre. It removes waxes and oils from the fibre to make it more receptive to bleaching and dying. In rayon it is used during the viscose process to extract cellulose from pulp. Caustic soda solution is used in the treatment of water by regenerating the anion resin bed. It is used on a large scale in DM plants." Approvals : "ISO 9001:2015 ISO 14001:2015" Cas No : 1310-73-2
