How to deal with the color of polyoxymethylene hose? How to ensure the color?

Each person's buttock red polyoxymethylene hose knows that the glossiness of these people is bright. There are some stainless steel plates in the plan and they can almost be used as bathroom mirrors. Polyformaldehyde hose is a kind of plastic hose made in Germany SPIRSTAR. The improved layer of the polyoxymethylene hose is a coiled layer of high-strength steel wire, which is specially solved. The inner rubber layer of the polyoxymethylene hose is polyoxymethylene (POM) or acrylic resin (PA), and the outer rubber layer is acrylic resin (PA) or polyurethane (PUR).

Is the color of all polyformaldehyde hoses bright? Neither.

Some customers think the color of the polyoxymethylene hose should be bright. When selecting plastic hoses for polyoxymethylene hoses, appropriate plastic hoses, connectors and the total length of plastic hoses shall be selected according to the special use place. In fact, if you touch more, you will find that some types of polyoxymethylene hoses are silver or even dark dark gray. For example, 316L stainless steel corrugated pipe with raw material quality is not bright silver.

The color of polyoxymethylene hose is bright, which is the difference between 304 and ordinary polyoxymethylene hose. Later, I learned that some 201 material polyoxymethylene hoses are also bright in color, while some polyoxymethylene hoses are dark in color.

In fact, the basic reason for the bright color of the polyoxymethylene hose is that the electroplating process or polishing is selected, while some polyoxymethylene hoses will reduce their glossiness due to the processing process, such as the use of pickling and passivation, but the corrosion resistance is not affected.

The polyoxymethylene hose is mainly composed of a liquid resistant inner rubber layer, a medium rubber layer, 2 or 4 or 6 layers of steel wire coiled and raised layers, and an outer rubber layer. The inner rubber layer has the effect of making the transport material bear, maintaining the steel wire rope from corrosion, and the outer rubber layer protects the steel wire rope from damage. The steel wire layer is the raw material of the frame to improve the efficiency.
