Coupling agent is an important, widely usedin the field of treatment agent, mainly for polymer composites additives. Themost important characteristic of the molecular structure of the coupling agentis that the molecule contains two groups with different chemical properties.One is a group of pro-inorganic, easily with the inorganic surface of thechemical reaction; the other is the pro-organic groups, and synthetic resin orother polymer chemical reaction or hydrogen bond dissolved in them. So thec ...

Glass fiber reinforced plastic: Improve thephysical and mechanical strength of the composite wet, wet electricalperformance, and improve the glass fiber cluster, protection and processingtechnology.Adhesives and coatings: Improve the wetadhesion, weatherability, improve pigment dispersion, improve wear resistanceand resin crosslinking.Casting: Improve the strength of resinsand. To achieve a high degree of low gas evolution.Rubber: Improve product mechanicalstrength, wear resistance, wet electric ...

Coupling agent is very common in our liveschemical raw materials. In plastic compounding, the coupling agent is toimprove the synthetic resin and inorganic filler or reinforcing materialinterface properties of a plastic additive, coupling agent, also known assurface modifier. It can reduce the viscosity of synthetic resin melt in theplastic processing, improve the dispersion of filler to improve the processingperformance, thus enabling the products to obtain good surface quality andmechanical, t ...

Curing agent can be divided according touse at room temperature curing agent and heat curing agent. Epoxy resin at hightemperature curing general good performance, but in civil construction in theuse of paint and adhesives due to heating difficulties, need room temperaturecuring. So most of the use of fatty amines, ring lipids and polyamide, and soon. In particular, coatings and adhesives used in winter have to be used incombination with polyisocyanates, or polyhalines having a malodorous odor.A ...

The curing temperature of the curing agentand the heat resistance of the cured product has a great relationship. Similarly,in the same type of curing agent, although the same functional groups, but dueto different chemical structure, its properties and curing properties aredifferent. Therefore, a comprehensive understanding of the same functionalgroups and different chemical structure of the polyamine curing agent of thetraits, characteristics, the choice of curing agent is very important.In ter ...

The silicone polymer is a polymer compoundhaving a silicon atom in its main chain. At present the most importantorganosilicon polymer is polysiloxane. Polysiloxanes are polymeric, chain-like,cyclic or reticular polymeric compounds that are polymerized from many monomerscontaining double bonds, commonly known as silicones. Its structure ischaracterized by containing a silicon, oxygen atoms alternately arranged in thebasic skeleton, each silicon atoms are connected with organic groups. Thesilicon- ...

Silicone is a very good nature of thepolymer material, with good temperature resistance, weatherability,physiological inertia and insulation properties. Electronics, biomedical,aerospace, machinery, shipbuilding and daily-use industries have a wide rangeof applications. Silicone materials from the morphology of a gaseous, solid,liquid, etc., can be cross-linked into a solid membrane. Can also be a soft elastomer,can be room temperature crosslinking, high temperature crosslinking can also beappli ...

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 ...
