Product Description

Also known as helical or spiral tube body. Spiral tube outer diameter of about 30 nm and an inner diameter of about 10 nanometers, adjacent helical pitch of about 11 nm. 1 week of each spiral from 6 surrounded nucleosome, H1 histone in the spiral cavity of the inner surface of maintenance of spiral structure plays an important role. The nucleosome composed of 10 nm, 30 nm fiber to form spiral of crude fiber, so that further compression 6 times the length of DNA.

Surface treatment

1, cleaning

Application solutions, emulsions cleaning steel look to reach the removal of oil, grease, dust, smoothing agents, and similar organic matter, but it does not remove the steel appearance of rust, scale, welding flux, and thus the corrosion produced only as adjuvant trick.

2, tool rust

The primary use of tools such as steel wire brush polished look, you can remove loose or tilt of the oxide scale, rust, welding slag. Hand tools rust can reach Sa2 level, power tools rust can be reached Sa3 level, if the outer steel skin attached to solid iron oxide, the results are not ideal tools rust, corrosion of the anchor pattern depth of less than construction requirements.

3, pickled

Common chemical and electrolytic pickling two ways to do disposal pipeline corrosion using only chemical pickling can descaling, rust, old coatings, and sometimes used as a sand-blasting and then disposed of after. Chemical cleaning is important in allowing the appearance of the inevitable arrival of cleanliness and roughness, but the anchor pattern shallow, and easy on the case of forming pollution.

4, spray (throwing) radio rust

Spray (throwing) radio rust is the result of high-power motor driven spray (throwing) radio blade speed reverse, so that grit, steel shot, wire segments, minerals and other abrasive under the centrifugal effect of the outer pipe were shot dispose spray (throwing) not only can completely eliminate rust, oxides and dirt, and steel in the fierce impact and abrasive friction effects, but also to reach an average roughness needs.

Spray (throwing) radio rust, it can be extended not only physical adsorption outer tube, and can enhance the effect of the mechanical adhesion of the coating and the outer tube. Thus, the spray (throwing) radio rust rust is an ideal method for pipeline corrosion. Generally, blasting (sand) blasting is mainly used for disposal of the tube look, blasting (sand) blasting is mainly used for surface of the pipe surface disposal.
