Heavy-duty coating with crosslinking agent,Anticorrosion coating is used in the pipeline and storage tank of the heavy-duty type. The characteristics of the heavy-duty coating is the coating thickness, good performance, long life, adapted to the harsh working environment. Heavy-duty coating can be acknowledged and get a lot of application, first of all depends on the scientific formula, it is more important and site construction technology.
Has formed a series of the coating has the world advanced level, and formed a series of associated formula technology standard, product technical standard, construction standard, site construction inspection standards mature technical data.
Heavy-duty coating judgment method. According to the national standards, industry standards and enterprise standards requirements, to see if it has particularity. Judgment method is roughly as follows:
The thickness of the coating large (D8640 crosslinking agent used)
The general anticorrosion coating thickness in microns, and heavy-duty coating is in mm.
Can work in harsh environments (D3050 crosslinking agent used)
General anticorrosion coating always work in the air, and heavy anticorrosive coating in corrosive medium long-term direct immersion in the work. For example: the anticorrosive layer of buried pipelines in groundwater (fresh water or sea water), underground acid soaking, alkali or salt of strong corrosive medium under the work; At the same time, also the erosion underground anaerobic bacteria and plant roots.
In anti-corrosion of the oil storage tanks requires in acid medium and large amounts of water in the crude oil. The work environment than the average coating environment more bad, this is the nature of work, heavy-duty and general anticorrosion technology cannot achieve.
Coating of long service life (D8640, D3050 crosslinking agent used)
According to a large number of practice experience and data at home and abroad show that the service life of heavy-duty coating in 15 to 20 years. Sewage pipeline, work for more than 20 years, coating for modified asphalt, 7 mm thickness, spark leak detection 20000 v.
Unique performance (D3050 insolate not yellowing, 1000 hours of boiling water, acid and alkali resistance, 0 ℃ for 24 hours all crosslinking etc, belong to the universal crosslinking agent.)

Heavy-duty coating, poor working conditions because of the large thickness, coating, long life and other characteristics, determines its characteristics must be unique, otherwise, it is difficult to meet the above requirements. The characteristics of coating specific summarized as the following:
(1) have strong waterproof can work in water for a long time, will also be able to work for a long time under the erosion of anaerobic bacteria;
(2) the strong resistance to chemical media, excellent acid, alkali, salt, oil field sewage and other chemical properties;
(3) the cathodic disbonding resistance; The soil corrosion resistance; Anaerobic bacteria resistance, plant roots to wear head, soil stress corrosion; Conductive resistance to the ground and underground facilities such as railway, wires, trams, etc of the stray current corrosion resistance; The impact of the hard stuff in the soil corrosion resistance; For smoothly on cathodic protection must have the coating resistant to spark leak detection performance.
(4) every variety of heavy-duty coating must have electric insulation requirements.
(5) the uniqueness of the test project heavy-duty coating must do edm leakage test. To general anticorrosion coating, only when it comes to performance test routine performance testing, such as: viscosity, dry resistance, adhesion, flexibility, impact strength, water resistance, heat resistance, chemical resistance, etc.
