The epoxy glass fiber tube is made of
thermosetting epoxy resin as the main raw material, air is used as the
dispersion medium, and the powder is evenly sprayed on the surface of the preheated
steel tube with the help of high-speed airflow and electric attraction.
Under the action of high temperature, the
powder melts into an anti-corrosion layer of uniform thickness. The coating has
no solvent pollution, no need to consider fire protection measures during
construction; fast curing speed; thickness can be from tens of microns to
hundreds of microns, with good toughness, no cracks when the pipe is bent; its
advantage is that it has great adhesion to the metal surface , Good bonding performance,
resistance to cathodic disbondment; easy to repair; strong resistance to soil
stress, suitable for most severe corrosive environments such as high salt, high
alkali, and cold.
It is widely used in the coating of the
inner wall of water supply equipment such as drinking water tanks, water pipes,
water tanks, water towers, and used in the cargo holds of sugar and grain. Used
in coal mine drainage systems, gas drainage pipes, positive and negative
pressure ventilation pipes, fire-fighting pipes and long-term supply of plastic
sprinkler systems. It can also be used as the inner wall coating of swimming
pools, cooling towers of power plants, and metal and concrete containing fuel
oil and gasoline.
The epoxy glass fiber tube is made of
electrical alkali-free glass fiber cloth impregnated with epoxy resin, and
processed by baking and hot pressing in a forming mold. The cross section is a
round rod. The glass cloth rod has high mechanical properties. Dielectric
properties and good machinability.
The heat resistance grade can be divided
into B grade (130 degrees), F grade (155 degrees), H grade (180 degrees), and C
grade (above 180 degrees). It is suitable for insulating structural parts in
electrical equipment, and can be used in damp environment and transformer oil.
The surface should be flat and smooth, free of bubbles, oil stains and
impurities. Color unevenness, scratches, and slight height inequality that do
not hinder use are allowed. Laminated glass cloth rods with a diameter of more
than 25mm are allowed to have cracks on the end or section that do not hinder
use.
