The detection method and related tools introduction of the inner diameter of silica gel glass fiber tube

The following introduces the inspection method of the inner diameter of the Silicone Glass Fiber Tube. The regular inner diameter of the silicone glass fiber tube can be produced from φ1.0 to φ30 for quality inspection, and the special size should be customized by consulting the manufacturer.

1. Inner diameter:
The inner diameter of the fiberglass casing of the selected specification should be greater than the maximum outer diameter of the quilt. To detect the inner diameter, the specified detection tool should be used: needle gauge.
testing method:
1. Cut the test end of the test piece flat;
2. Hold the tested part with the left hand, and the pin gauge with the right hand, align it with the round hole of the part and insert it vertically, read according to the value marked on the surface of the pin gauge, and keep the estimated value with two decimal places;
3. After the needle gauge is used up, it should be put back to its original place and kept properly.
Precautions:
1. The test end of the test piece should be cut flat before the test, so as to facilitate more accurate reading of the value.
2. When reading the reading, the inspector should look at the scale line of the ruler.
3. Do not use excessive force to prevent damage to the needle gauge and inaccurate measurement data.
4. Selection of needle gauge According to the size of the hole diameter of the tested part on the drawing, within the diameter range, first select the needle gauge with the smallest specification.
Silicone glass fiber tube is braided into a tubular shape by alkali-free glass fiber, then coated with silicone resin, and then finished by high temperature treatment. It has good dielectric properties, good flexibility, flame retardancy and temperature resistance. Widely used in heat insulation and insulation of motors, household appliances, electric heating equipment, electronic devices and bundled wires.
When it comes to the color of silicone fiberglass tube, the first thing that comes to mind is its true color: white. The main raw material glass fiber filaments mainly derived from silicone glass fiber tubes is white, so white is the most common color of silicone glass fiber tubes, and the price is relatively cheap.
Secondly, the silicone fiberglass tube can also be made into black. Black is the second main color of the silicone fiberglass tube, which is dirt-resistant and versatile. Others such as red, yellow, blue, green, gray, etc.
Based on the above summary, the main color of silicone glass fiber tube is white, followed by black, red, yellow, blue, green, gray, orange and so on.
When it comes to the selection of fiberglass sleeves, we must first determine whether the customer wants to buy a fiberglass sleeve. It is hollow inside and is often used for threading, insulation protection, and a type of sleeve. After confirming that it is a fiberglass sleeve, we will continue Determine the parameters of the fiberglass casing.
1. Color, the natural color of the fiberglass casing is white, colors such as red, brick red, yellow, blue, green, black, etc. can be customized, of course, the price of the natural color is relatively cheap;
2. Withstanding voltage, glass fiber bushings are divided into 1.5KV, 2.5KV, 4KV and 7KV according to the withstand voltage level;
3. Material, the most commonly used is silicone resin silicone glass fiber tube, followed by inner fiber outer rubber glass fiber sleeve;
4. Finally, it is necessary to provide the required inner diameter, and the specification of glass fiber tube can be made from 0.5mm to 30mm.
