Description

Carbon steel lined polyethylene panels for sinks

technical field

The utility model relates to a carbon steel lined polyethylene plate for washing pools with improved corrosion resistance and durability.

Background technique

In the process of producing titanium dioxide by the sulfuric acid method, the washing tank (including the first washing and the second washing) is usually lined with carbon steel glass fiber reinforced plastic or rubber. The fiberglass-lined steel is limited by the construction process, and the fiberglass is very easy to delaminate and bulge. Lined glass fiber reinforced plastics generally fall off and leak after 3 months of use, which not only affects production, but also has relatively high maintenance costs. In particular, maintenance is required for at least 24 hours after repairing due to corrosion and peeling off, which greatly affects production. However, with the rubber lining process, due to the need to regularly clean the metatitanic acid in the pool, the rubber layer is easily damaged.

Accordingly, there is a need in the art for a carbon steel substrate with improved corrosion resistance and durability.

Utility model content

The purpose of the present utility model is to provide a carbon steel lined polyethylene plate for washing pools with improved corrosion resistance and durability. The carbon steel lined polyethylene plate includes a carbon steel base and is arranged on the carbon steel A layer of linear low density polyethylene on a substrate, wherein a steel mesh is disposed between the carbon steel substrate and the layer of linear low density polyethylene by welding to the carbon steel substrate.

The linear low density polyethylene layer may have a thickness of 15 mm to 25 mm.

Description of drawings

In the drawings, "1" indicates a carbon steel substrate, "2" indicates a steel wire mesh, and "3" indicates polyethylene.

Detailed ways

The following describes the carbon steel-lined polyethylene plate for the washing pool according to the present invention.

Generally speaking, the carbon steel lined polyethylene plate for washing pool according to the present invention comprises a carbon steel substrate and a linear low density polyethylene layer arranged on the carbon steel substrate, wherein the steel wire mesh is welded on the carbon steel substrate Instead, it is set between a carbon steel substrate and a layer of linear low density polyethylene.

Typically, the linear low density polyethylene layer may have a thickness of 15mm to 25mm. However, the thickness of the linear low-density polyethylene layer is not limited thereto, and may be appropriately changed as needed.

An example of a carbon steel-lined polyethylene plate for a washing pool according to the present invention will be described below with reference to the accompanying drawings.

Fig. 1 schematically shows a cross-sectional view of a carbon steel-lined polyethylene plate for a sink according to the present invention. Referring to Fig. 1, the carbon steel lined polyethylene plate for the washing pool comprises a carbon steel substrate 1 and a linear low density polyethylene layer 3 arranged on the carbon steel substrate 1, wherein the steel wire mesh 2 is welded on the carbon steel substrate 1 And it is arranged between the carbon steel substrate 1 and the linear low density polyethylene layer 3 .

Specifically, the linear low-density polyethylene layer 3 is formed by linear low-density polyethylene, and the linear low-density polyethylene is ethylene and a small amount of α-olefin (for example, 1-butene, etc.) A copolymer formed by polymerization, the density is about 0.93g/cm ³ , it has the advantages of high strength, good toughness, strong rigidity, heat resistance, cold resistance, etc., and also has good environmental stress resistance, tear resistance and other properties. In addition, it can also be resistant to acids, alkalis, and organic solvents.

Before applying LLDPE on the carbon steel substrate 1, the carbon steel substrate 1 is first polished and derusted, and then the steel mesh 2 is welded on the carbon steel substrate 1, and then the powdered LLDPE is pumped onto the carbon steel substrate 1 welded with the steel wire mesh 2 , and melt the powdered linear low density polyethylene, followed by cooling, so that a linear low density polyethylene layer 3 of desired thickness can be obtained on the carbon steel substrate 1 . The purpose of welding the steel wire mesh 2 on the carbon steel substrate 1 is to increase the adhesion with the carbon steel substrate and ensure its service life.

In one example, a linear low density polyethylene layer 3 may be formed on a carbon steel substrate 1 with a thickness of about 15 mm. In another example, a linear low density polyethylene layer 3 may be formed on a carbon steel substrate 1 with a thickness of about 20 mm. In yet another example, a linear low density polyethylene layer 3 having a thickness of about 25 mm may be formed on the carbon steel substrate 1 . A linear low density polyethylene layer 3 having a desired thickness can be formed on the carbon steel base 1 as required.

In the process of forming the linear low-density polyethylene layer 3, it is preferable to ensure that the formed surface is smooth, free of hang-ups and undispersed raw materials, free of cracks, free of bubbles and substantially smooth, so that the obtained carbon steel-lined polyethylene plate Optimized for performance.

It has been confirmed by industrial production that no corrosion leakage has occurred in the washing tank using the carbon steel lined polyethylene plate according to the utility model for one and a half years, which ensures continuous production, improves production capacity and yield, and eliminates the need for production on site. The phenomenon of material running, popping, dripping, and dripping occurs, and the maintenance cost is greatly reduced at the same time.
