IPN8710 corrosion-resistant steel pipe
details
Advantages of IPN8710 Corrosion Resistant Steel
Especially in those very dark and humid, very much corrosion of the place, more need to use this pipe. Such as sewers, where the sewage, all kinds of waste, etc., is a more subtle place, it is difficult to find, when the steel pipe rupture and other damage, the difficulty of maintenance is very high, so the use of this pipe can be extended use Time, anti-corrosion function more. IPN8710 anti-corrosion steel pipe really bring a lot of convenience for people, and perhaps someone would want to corrosion on the new, of course, not difficult to buy a new pipe, but the replacement process is really very troublesome, so IPN8710 corrosion pipe is People save time, effort, and seek to facilitate the steel pipe.
IPN8710 anti-corrosion steel pipe of the comprehensive performance:
1, the surface treatment is simple;
2, anti-corrosion performance;
3, reasonable cost performance.
According to the thickness of the steel pipe, the thickness of the coating and the requirements of the epoxy zinc-rich primer, the steel pipe body must be subjected to mechanical rust treatment (shot blasting or sandblasting). The steel surface cleanliness and roughness reach the following indexes:
1, cleanliness: to gb8923-1988 the sa2.5 level, the level of text is defined as: a very thorough clean-up jet. In the case of observation without amplification, the surface should be free of visible grease and dirt, and there is no scale, rust, old coating and foreign matter, only residual dot or streak-like trace.
2, roughness: also known as the surface space of steel space, from the lowest valley to the highest peak of the surface height of the surface is measured, the surface treatment level of safety technical indicators. In the sy / t0447-96 standard for epoxy asphalt paint has the relevant roughness requirements. Steel pipe surface roughness should be controlled at 70 ~ 90μm, gb / t13288 standards are sand-shaped abrasive in the middle or the primary pill-shaped abrasive.
Anti - corrosion coating of IPN8710 anti - corrosion steel pipe
IPN8710 anti-corrosion steel pipe it is two-component coating, Group A base material: resin, initiator; B group base material: active monomer, catalyst. The interpenetrating polymer networks (IPN) are formed at the molecular level to form the interpenetrating polymer network (IPN) structure. The network has the following advantages: strong adhesion, good flexibility, Acid, alkali, salt and other corrosive media. Which can further improve the toughness, strength, adhesion, anti-permeability and chemical inertness of the coating. It can improve the performance of the polymer by forming IPN, and is a new type of polymer blending technology.
