The selection of heat shrinkable tube specification and model, the content to be considered in selecting heat shrinkable tube
Selection of specification and model of heat shrinkable sleeve
The heat shrinkable sleeve has excellent flame retardant, insulating layer and heat resistance. It is made of special polyolefin heat shrinkable tubing. Bad people also make EVA raw material profiles. Here, people can be careful how to standardize the use of it.
1、 Purchase of specifications and models
Generally speaking, the diameter is 70%, which is basically similar to the diameter of the affected components. For example, if you use a centimeter cylinder, people can buy a cylinder with a diameter of 29 cm before heating. However, it should be noted that if the specification exceeds 40 cm, it is better to set the value to 60%.
2、 Determination of gas insulation gap after bus duct operation
For the actual value, people can refer to the whole process coding in "bus duct manufacturing and installation". If it is 2.35kv, the distance between the top gas insulation layers after the heat shrinkable film is not allowed to be greater than 220mm. People are not allowed to pay attention to this value, it is not absolutely about this value.
3、 A small amount of busway and heat shrinkable sleeve are often in doubt
1. Pay attention to the burr and bevel angle on the bus duct after operation, otherwise the bus duct will pierce through PVC heat shrinkable sleeve and crack when heating and closing.
2. Before application, the quick drying detergent should be used in advance to completely eliminate the connecting components. Therefore, the heating is only carried out after the elimination.
3. After laser cutting Chinese herbal medicine, guarantee the wound is neat and smooth. It is not suitable to have all the burrs or cracks. Otherwise, in view of the uneven heating, the cracks were randomly increased.
4. Different heating methods are available. People can use constant temperature oven, propane gas lamp, liquefied petroleum gas fire, automobile gasoline combustion engine and so on.
5. When you use industrial hair dryer for heating, you are not allowed to first pay attention to the heating from one port number, and then move it evenly to another port number to make it evenly folded by heating.
If the heating gun is used to heat the heat shrinkable tube, the temperature is generally controlled between 400 ℃ and 600 ℃. Attention should also be paid to the distance between the fire and the heat shrinkable tube, i.e. 4-5cm. It should be moved symmetrically and heated while moving. It is not necessary to heat too close to the surface or only in one area.
What should be considered in selecting heat shrinkable tube
In the next stage, we need to purchase a kind of heat shrinkable material, such as the use of heat shrinkable material.
1. Brand
At present, there are bad brands in the market. The way is conventional. For consumers, how to choose them will lead to special tangles. Which brand is particularly good? This is a puzzle that bad people pay special attention to. In the selection stage, it is best to select manufacturers with all aspects of production experience to purchase, so that we can absolutely solve and better ensure. If it is caused by doubts, we should go to the after-sales department, so we can solve the doubts more casually. Deep talk: This is not enough not to introduce our company, as one of the heat shrinkable tube manufacturers, the company has a fixed production line, with its own formula, has been adhering to the business philosophy of "quality brand as the basis, marketing as the center, and integrity technology or service as the guide" for ten years.
2. Performance
The most important feature of heat shrinkable tube is that it has good insulation and guarding ability, and it is also very strong in mechanical strength and has chemical resistance. In view of the fact that this kind of material is more critical to be used in the solder joints, inductors, wire harness insulation, anti-corrosion, protection and other contents, for a small number of cables and other connected lines, the absolute effect is very good, and it is a product with high cost performance and good performance.
3. Quality
There are all kinds of different standards on the thickness index. If the quality is particularly good, it can be particularly thick in the material. Therefore, if the thickness is particularly large, it will have better wear resistance, relatively more rigid, and strong ability to resist wear. Moreover, it is also very easy for each product's raw material profile, so the focus is also different. The key contents include chemical corrosion resistance, wear resistance, flame retardant, corrosion resistance, etc.
4. In fact, when we select the heat shrinkable tube, we need to consider the brand, performance and quality of the heat shrinkable tube easily. We also need to be cautious about what kind of environment we may use. We need to be more cautious only when we use our products. For example, if it needs to be used in the high temperature environment, we still suggest that we should know more about the heat resistance and flame retardancy of the material at the purchase stage. If it is used in a chemical plant, it is recommended to consider the ability to resist chemical corrosion.
In this way, in the selection stage of heat shrinkable tubes, the contents of the previous several methods should be considered carefully, so as to ensure the selection of high-quality heat shrinkable tubes.
