Metal ion coating crosslinking agent,Metal ion is a substance soluble in water after the metal ions. Simple said is of metal elements in the material.
Most of the metal ion is cation, but IVB - VIII metal can produce anion. Metal ion is osmotic balance of maintaining the polyphase system important constituent, is also a necessary component of a wide range of enzyme reaction. Some of the enzyme catalytic activity, in addition to protein parts, also need to metal ions, the metal ion is part of the enzyme active center.
Some of the enzyme molecule is not contain metal, but need to metal ions. Metal ion is the prosthetic group or activator of enzymes, the change of valence metal ions by itself to transfer electrons, complete biological REDOX reaction in the body, in the maintenance of water and electrolyte balance in organism, etc also need to metal ions.
Or molten state of ionization of the cationic full of H + is acid, such as HCl, - H2SO4, HNO3, H3PO4, etc.
Solution or melt in the state of ionization of the anion of OH - is the base of all such as Ca (OH) 2, KOH and NaOH, NH3 · H2O
(because of NH3 · H2O in water ionization can represent NH3 · H2O and NH + 4 + OH -, so also belong to the alkali NH3 · H2O), etc.
With acid radical ions and metal ions, or ammonium ions combined into substance is a salt, acid radical ion is the acid ionization anion, such as Cl -, SO42 - and NO3 -, PO43 -, etc.; Alkali metal ions, or ammonium ions is ionization of cation, such as Na +, K +, NH4 +, etc. NaCl salt, K2SO4, etc
Concept of metal ions,
1, acid, hydrogen ion + acid radical ion
2, alkali, metal ions and hydroxyl ions
3 + acid radical, salt, metal ions
4, double decomposition reaction, consisted of two compounds to exchange, to generate the reaction of the other two compounds, called double decomposition reaction. AB + CD = AD + CB
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packingļ¼ net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
5, dilute sulfuric acid method, be sure to slowly along the wall, concentrated sulfuric acid is injected into the water, and stir constantly, make the heat spread quickly, must not pour the water in concentrated sulfuric acid.
6, neutralization reaction effect with bases to form salts and water - acid reaction is called a neutralization reaction.
All water as solvent or paint as dispersion medium, can be called a water-based paint, water-based coatings including water-soluble coating, water dilute coatings, water dispersion paint, latex paint) 3 kinds.
Also known as synthetic resin emulsion paint, latex paint is a kind of organic coating, synthetic resin emulsion as basic material made from add pigment, filler, and various additives of water-based paint.
A two-component polyurethane waterproof coating materials (), component based on polyether resin and diisocyanate etc. Raw materials, through the reaction of polymerization and contains the isocyanate based polyurethane prepolymer. Component b is by the crosslinking agent, promoting agent, toughening agent, fungicide, filler and dilute agent processing.
Epoxy powder and other powder coating, drinking water production process is simple, and suitable for water spraying operations. Coating non-toxic, no pollution to water quality.
This coating since developed, used for water supply pipeline anticorrosion. The user evaluation that the epoxy powder coating has excellent mechanical properties, chemical corrosion resistance and resistance to microbial breeding performance, application is very suitable for water supply pipeline caused by corrosion.
