Abstract
The utility model relates to a coal tar enamel external winding belt, which belongs to the field of layered products. The utility model is used for anticorrosion usage, and is composed of backing material, an anticorrosive layer, and an insulating layer. Two faces of the backing material are uniformly coated with the anticorrosive layer, and the anticorrosive layer is provided with the isolation layer; the anticorrosive layer uses coal tar enamel or asphalt. The utility model is a type of long-term anticorrosive material, and has the advantages of low water absorpt ratio, excellent insulating property, antimicrobial erosion, resistance for plant root penetration, resistance for petroleum product soaking and good chemical stability. The utility model is especially suitable for antiseptic treatments of buried underground pipelines.
Description
The outer tape wrap of the utility model coal tar enamel belongs to the laminar product field, and it is to be used for anticorrosion purposes.
On pipeline, apply one deck corrosion resistant coating in the existing pipeline corrosion protection, the anticorrosion time is short, adopt outer tape wrap to be wrapped on the corrosion resistant coating coating on steel pipe surface, be used to strengthen the ability of cover layer opposing external mechanical influence, to guarantee inhibitor effectiveness, improve the performance of outer tape wrap, can prolong the anticorrosion time effectively.
It is a kind of that the purpose of this utility model is to provide, and can improve antiseptic property, prolongs the outer tape wrap of coal tar enamel of anticorrosion time.
The utility model is made up of base material, anticorrosive coat, separation layer.At the even anticorrosive coating in the two sides of base material, on anticorrosive coat, be provided with separation layer.Base material is used for anticorrosive coating, and base material adopts ribbon, can be wrapped on the pipeline; Anticorrosive coat is to be coated on the base material with anti-corrosion material to form, and plays antisepsis; Separation layer is for preventing that outer tape wrap interlayer from sticking together.Base material of the present utility model can be selected glass mat for use, or glass fibre non-woven or polypropylene non-woven fabric, or terylene non-woven fabric, thickness evenly is coated with anticorrosive coat greater than 0.3 millimeter on the two sides of base material, anticorrosive coat material selection coal tar enamel or pitch, thickness is even during coating, and the two sides all should fully be covered by coal tar enamel, and separation layer adopts sand, or talcum powder, or coal dust.
The utility model is a kind of long-effective corrosion material, and it is low to have a water absorption rate, and insulating properties is superior, antimicrobial erosion, anti-plant roots and stems penetrates, anti-oil product soak and chemical stability good, be specially adapted to be embedded in the preservative treatment of underground piping.
Accompanying drawing case 1 is an example structure schematic diagram of the present utility model,
Accompanying drawing case 2 is example structure schematic diagrames of the present utility model,
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model is to make base material (1) by glass mat, evenly is coated with one deck corrosion-resistant coal tar enamel (2) on the two sides of glass mat, is provided with the sand (3) of anti-adhesion on anticorrosion coal tar enamel.
As shown in Figure 2, the utility model is to make base material (4) by glass fibre non-woven, evenly is coated with one deck corrosion-resistant pitch (5) on the two sides of glass fibre non-woven, is provided with the talcum powder (3) of anti-adhesion on corrosion-resistant pitch.
Claims (3)
1, the outer tape wrap of coal tar enamel is characterized in that being made up of base material, anticorrosive coat, separation layer, at the even anticorrosive coating in the two sides of base material, is provided with separation layer on anticorrosive coat, and anticorrosive coat adopts coal tar enamel or pitch.
