IPN8710 water pipe anticorrosive steel pipe
IPN8710 water pipeline anticorrosion really brought a lot of convenience for people, one might think that the corrosion in the new, buy a new tube, of course, is not difficult, but the process of change is really very troublesome, so IPN8710 water pipe anti-corrosion steel pipe is convenient for people to save time, effort, the steel pipe. Especially in places that are extremely dark and humid, where there is a lot of corrosion, you need to use this kind of steel tube much more. Like sewers, where sewage, all kinds of waste material, and so on, it is more secluded place, it is difficult to find, when the damage such as steel tube ruptures, maintenance difficulty is very high, so use this kind of steel tube can prolong the using time, the anti-corrosion function stronger.
Comprehensive performance of IPN8710 water pipeline anticorrosive steel pipe:
1. Simple surface treatment;
2. Excellent anticorrosion performance;
3. The performance price is reasonable.
According to the regulations of steel tube thickness, coating film thickness and the requirement of epoxy zinc-rich primer, must through mechanical derusting processing production line of steel tube body (or sand blasting), steel surface cleanliness and roughness to achieve the following indicators:
1. Cleanliness: to the sa2.5 level of gb8923 -- 1988. The text of this level is defined as: a very thorough jet cleaning. In the absence of magnification, the surface of the surface should be inapparent grease and dirt, and no oxide, rust, old coating or foreign matter, only slight or striate marks.
2. Roughness: also known as the surface profile of steel space, the surface profile height measured by the lower part of the valley to the height of the peak is the safety technical index of surface treatment grade. The requirements for the roughness of the epoxy tar paint are in the sy/t0447-96 standard. The surface roughness of the steel tube shall be controlled at 70~90 mu m, which belongs to the intermediate or pellet abrasive material of gb/t13288 standard.
IPN8710 water pipe anticorrosive coating for anti-corrosion
The IPN8710 water pipeline anticorrosive steel pipe is a double component coating, a base material: resin and initiator. Group b base material: active monomer, catalyst. Students' mixed with equivalent b, three kinds of interpenetrating network at the molecular level, forming interpenetrating polymer network (IPN) structure, produce synergies, the coating forming network has: good adhesion, flexibility, acid, alkali, salt and other corrosive medium. To further improve the toughness and strength of the coating permeability, adhesion, resistance and chemical inertness, make coating has better performance, through the formation of IPN to improve the performance of the polymer, is a new kind of polymer blending technology.
