Microencapsulated coating crosslinking agent
Microcapsule type latent epoxy resin agent intercourse is, in fact, using physical methods, the bi-component crosslinking agent at room temperature using fine droplets membrane package, the formation of microcapsule, join the epoxy resin will crosslinker crosslinked reactivity after temporarily closed up, and by heat, pressure condition such as the capsule rupture, releasing the crosslinking agent, so that the epoxy resin crosslinking.
Microcapsule type latent epoxy resin intercourse of film-former including cellulose, gelatin, polyvinyl alcohol, such as polyester, polysulfone, due to the strict preparation technology, the thickness of capsule membrane for storage, transportation and use will bring different degree of influence.
Asphalt coating for patching and repair, can use petroleum asphalt (hot) construction, also can use cold asphalt polyurethane coatings (construction) at room temperature, but must not use glass flake coating and epoxy coal asphalt;
The filling and repair of the glass scales, and the coating of glass, which is not made of petroleum asphalt and polyurethane coating.
Anti-static coating for patching and repair, can use antistatic coatings (construction) under normal temperature, to ensure good electrical conductivity and stability of the coating, asphalt and polyurethane coating repair is not available.
In any new tank, anti-static paint, glass flake coating, phenolic epoxy paint, thick slurry epoxy reproof paint can be selected.
Any new type of pipe can be used in any type of glass scale paint, phenolic epoxy paint, thick slurry epoxy.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
The new steel surface should be sprayed with sand treatment to reach the ISO standard Sa2.5 level or the electric tool rust St3 level. The surface of the shop primer shall be dry, clean and clean, and the paint film damage and rust will be removed at the Sa2.5 level or St3 level. Weld and burn damage to Sa2.5 or St3. When exposed to atmosphere construction under the condition of the far end of the substrate temperature is 5 ℃ to 40 ℃ and 3 ℃ above dew point. Relative humidity < 85%. Construction is prohibited under the weather of fog, rain, snow and wind.
The clean surface treated with the above method must be applied within a short period of time after treatment. The average time shall not exceed 8 hours.
Accordance with the appropriate methods should be adopted before the coating is peeling, cross fork or cross lattice method, for example, if the peeling to remove aging coating, surface must be no oil, grease and other pollutants. After the coating is completely dry, the coating appearance, thickness, adhesion, spark leak detection and other project inspection, unqualified must be made up to be qualified.
First, we should adhere to the national security production policy and relevant safety regulations of "safety first, prevention priority and comprehensive governance", and adhere to the HSE (health, safety and environment) philosophy. The construction personnel must be trained and studied before using the product, should pay attention to safety matters when using, avoid inhaling solvent vapor or paint, swallowing, skin contact, etc.; Wear protective equipment; Ventilation and ventilation; Do not use fireworks to prevent flammable and explosive; The construction site is equipped with foam, carbon dioxide and dry powder fire extinguishers.
Heavy anti-corrosion coatings are widely used in oil, chemical, oil refining, gas, municipal construction, water conservancy and other heavy industry pipelines, storage tanks and various metal components. It can effectively reduce all kinds of medium and environment of storage tank and pipeline corrosion, prolong service life, and the cost is low, air dry good, construction is convenient, to reduce the environmental pollution, save investment plays a remarkable economic benefit and social benefit.
