Polyacrylic acid sodium is a matureindustrial products, there are industry standards. The standard number is: HG /T2838-2010. Standard product appearance is colorless to yellow liquid, solidcontent greater than or equal to 30%.High relative molecular mass forflocculants.Water treatment agent - flocculantPolyacrylic acid sodium is a linear,soluble polymer compounds, the molecular chain of the carboxyl group due toelectrostatic repulsion. So that the polymer chain stretches around, causingthe adso ...
With the rapid development of the nationaleconomy, the necessity of water treatment is increasingly prominent,flocculation technology is to improve water treatment efficiency of the mostcommonly used technology. Especially as the flocculant high molecular weightpolyacrylic acid sodium, has become the subject of domestic and foreignresearchers competing research. In this paper, the emulsion polymerization ofacrylic acid and its comonomer is studied. The choice of emulsifier, the choiceof initiato ...
Health HazardsInhalation, ingestion of the eye andrespiratory mucosa have a strong stimulating effect. High concentrations, cancause corneal opacity, respiratory inflammation, and even pulmonary edema, andmay be associated with dizziness, headache, fatigue, nausea, vomiting,palpitation and other symptoms. Splashed on the skin, can cause necrosis,ulcers, long-term unhealed.First-aidSkin contact: Immediately removecontaminated clothing, mobile water rinse for more than 15 minutes. If burns,medical ...
Silane SiH4 in the hydrogen atoms arereplaced by chlorine atoms, the total known as chlorosilane, low chlorinecontent when the gas, the higher the liquid, colorless or yellow, N = 0, 1, 2,3;Chlorosilane with active hydrogen compoundswith a fierce reaction, such as water, alcohols, phenols, silanol, organic acids,etc., release hydrogen chloride.With the organometallic compounds, chlorineatoms are replaced by the corresponding organic groups to generateorganochlorosilane or organosilane.The silico ...
Epoxy silane crosslinking agent is acolorless transparent liquid, mainly used in unsaturated polyester composites. Canimprove the mechanical properties of composite materials, electricalproperties, light transmission properties, in particular, can significantlyimprove the wet properties of composite materials.The main purpose:Mainly used in unsaturated polyestercomposites, can improve the mechanical properties of composite materials,electrical properties, light transmission properties, in partic ...
The isobutyl functional group-containingcoupling agent: isobutyltriethoxysilane, silane coupling agentThis product is high purity isobutyltriethoxysilane, small molecular structure can penetrate cementation surface, penetrateinto the concrete and exposed to acid or alkaline environment in the air andwater molecules in the base chemical reaction, Forming a water repellenttreatment layer, thereby suppressing the ingress of water into the substrate. Resultingin waterproof, anti-Cl, anti-ultraviolet ...
Can improve their bonding strength, waterresistance, weather resistance and other properties. Silane coupling agents canoften solve the problem of some materials can’t be bonded for a long time. Silanecoupling agent as the principle of the role of tackifier itself has two groups;A group may be bonded to the bonded framework material; While the other groupcan be combined with high molecular materials or adhesives, resulting inbonding interface to form a strong chemical bond, greatly improving th ...
Silane coupling agent in the adhesiveindustry, the specific application has the following aspects:1. In the structural adhesives in thebonding of metal and non-metallic, if the use of silane type tackifier, can becondensed with the metal oxide, or with another silanol condensation, so thatthe silicon atoms and the surface of the surface firmly contact. Such as in nitrilenovolac structure by adding silane as tackifier, can significantly improve thebonding strength.2. In the bonding glass fiber at ...
1. Used in the manufacture of polyethylenecross-linked wire, cable insulation and sheath material This product is animportant cross-linked polyethylene crosslinking agent. The cross-linkingprocess and the general peroxide crosslinking, radiation cross-linked, comparedwith a simple device, less investment, easy to control, used in a wide range ofpolyethylene density, suitable for the production of special shapes fan core,Out of high speed. Silane cross-linked polyethylene has excellent electrical ...
1. Water-soluble adhesivesWater as the solvent binder, there arestarch, dextrin, polyvinyl alcohol, carboxymethyl cellulose and so on.2. Hot-melt adhesivesThe adhesive is melted by heating and isused as a solid binder. General thermoplastic resin can be used, such aspolyurethane, polystyrene, polyacrylate, ethylene-vinyl acetate copolymer.3. Solvent-based adhesivesDo not dissolve in water and soluble in asolvent binder. Such as shellac, butyl rubber.4. Emulsion type adhesiveMore in the water was ...
