8710 anticorrosive steel pipe Cangzhou Haile Steel Pipe Co., Ltd

  Overview: there are many kinds of corrosive media in the water supply pipeline of 8710 anti-corrosion steel pipe, including acid, alkali, salt, oxidant and steam
The coating must be chemically inert and resistant to acid, alkali and salt corrosion
The coating shall be compact in structure, good in waterproof permeability, strong in adhesion, tough and plump
8710 anticorrosive steel pipe belongs to “ Chemical reactivity ” The coating is packaged in two components
Component A is resin and initiator, and component B is active monomer and catalyst
Therefore, before use, the two components must be weighed and proportioned according to the specified important proportion, mixed evenly and cured for 30 minutes according to the specified time before construction
The cured coating should be used up within 6-8 hours to avoid cement waste
The ratio is as follows: primer, component A: component B =1 barrel: 1 barrel
Please strictly follow the required proportion (or construct according to the proportion notified by the manufacturer at that time) finish paint, component A: component B =1 barrel: 1 barrel
Please apply the second coat of paint after the first coat of paint is applied in strict accordance with the required ratio (or the ratio notified by the manufacturer at that time)
It is better to wait more than 24 hours before applying the second coat of paint
After the paint is used, the end of the packaging barrel must be tightly sealed, otherwise it is easy to deteriorate due to moisture, alcohol and water
The paint film can be put into use only after it is dried at room temperature for 7-10 days

matters needing attention:
1
the product shall be stored in a cool, ventilated and dry place, isolated from fire source and away from heat source
2
this product is a thick paste coating, which can be applied thickly without sagging
Generally, it can be applied without diluent after the barrel is opened
3
after the coating is stored for a long time, it will precipitate slightly
It should be stirred before use
4
after the coating is prepared, it shall be cured for 20 minutes in summer and 1
5-2 hours in winter
Generally, it shall be used up within 8 hours, otherwise the viscosity will be thickened and it is difficult to construct
5
the top coat can be applied after the primer is surface dry
The interval at room temperature should not exceed two days, otherwise it will affect the bonding between layers
The time gap between the application of each layer of top coat should also be surface dry ipn” Is English “ interpenetrating polymer networks” Interpenetrating network
Interpenetrating network polymer is a new type of polymer anticorrosive coating researched and developed in recent one or two decades
It has the excellent performance of unusual polymer materials, and is one of the hot spots in the development of polymer materials, including polymers “ Alloy ” A good reputation
IPN series anti-corrosion coating is a kind of castor oil polyurethane and poly substituted ethylene interpenetrating network polymer
During the mixing and curing process of the coating, the rubber network of the former and the plastic network of the latter penetrate, penetrate and firmly adhere to the surface of the coating
It can prevent corrosion and decorate the material surface& ldquo; IPN” The series of anti-corrosion coatings have high strength, high toughness, impact and wear resistance, aging resistance, acid and alkali corrosion resistance, strong adhesion, hydrolysis resistance, gasoline, kerosene and other media, non-toxic and non combustible properties
Therefore, it is widely used
It is not only suitable for corrosion prevention of steel, but also for non-metallic components such as concrete and wood
In recent years, it has been widely used in water engineering, power plant, chemical industry, chemical fertilizer and other industrial sectors, as well as underground and aboveground engineering corrosion prevention of oil, gas and water transmission pipeline systems, civil structures and so on
