There are many types of PET woven sleeves. In order to improve the protective performance of PET woven sleeves, flame retardants will be added to the production process of PET woven sleeves to achieve the actual flame retardant effect. This type of flame retardant woven network pipe is currently used in many fields. Gradually widely used, what is the high flame-retardant PET flexible braided network pipe? Let me tell you about the PET Braided Sleeve below.
High flame-retardant PET flexible braided mesh does not mean that the product itself has the characteristics of non-ignition, but it has the function of preventing ignition, which can prevent the spread of flames to a certain extent. The flammability level is VW-1, and the flammability level is 28. Its function is that it can be extinguished by itself within 30S, so as to achieve the purpose of flame retardant.
1. The difference between high flame retardant PET flexible braided network pipe
1. Most of the high-flame-retardant PET flexible braided network pipes are black, because the flame-retardant performance of black PET braided sleeves is better than that of colorful ones;
2. Medium-thickness PET braided sleeves can be judged by the chef whether it is flame-retardant or not, and the half-hard words in front of the name are yes, no, and non-flame-retardant;
3. PEPET braided sleeves can be judged according to the appearance whether it is flame-retardant or not. The bright surface layer of PET braided sleeves made of PE material is non-flame-retardant, and the sub-surface is only flame-retardant;
4. Heat-resistant PET braided sleeves with an operating temperature of ≥150°C are generally high flame-retardant PET flexible braided network pipes.
2. The main application of high flame retardant PET flexible braided network pipe
1. The high flame-retardant PET flexible braided network pipe will not short-circuit fault under the load of 600V working voltage and 125°C. It is a continuous circuit. At this stage, it is mainly used in the production and manufacture of flame-retardant cables and wires, and the flame-retardant protection of electronic components. The application is high The cables, wires and electronic components protected by flame-retardant PET flexible braided network pipes can ensure the smoothness of power engineering and communication cables in the event of a fire accident.
2. High flame-retardant PET flexible braided network pipe can also be used as protection for power engineering and communication line pipelines. In case of fire, it can prevent the spread of fire and avoid damage to power engineering. It can protect products very well and increase the service life.
With the rapid development of the field of PET braided sleeves, people's demand for products is getting higher and higher. Stainless steel PET braided sleeves gradually replace the bellows traditionally used in automobiles. It is made of polyester textiles and has no shrinkage. The flexible sleeve has the characteristics of light weight, good flexibility, friction, sound reduction, and high cost performance. The main reason is that it inherits the advantages of bellows, saves indoor space more than bellows, and fills the gap between Easy to bend this important enough.
Therefore, for fields with high safety requirements such as automobiles, high-speed rail trains, and machinery manufacturing, stainless steel braided sleeves will be very popular, because it can not only protect wire harness cables, but also has beautiful and elegant effects, especially for irregular shapes. In the wiring harness industry, the open-mouth structure is more beneficial for internal wiring harness maintenance, reinstallation, maintenance and repair.
The metal material and air O2 reflect the oxide film, and the general carbon steel iron oxide is re-oxidized, causing the rust to expand and make holes. In order to protect the surface of the carbon steel, paint or oxidation-resistant metal materials can be used for electroplating, but this is only a plastic film. , if the protective layer is damaged, the lower steel will gradually rust.
In order to avoid further oxidation, make the stainless steel have the same surface, according to this oxide layer, you can see the luster of the stainless steel surface, if the surface is damaged, the steel surface will maintain itself with the air, and then form a passivation film, constantly exerting the actual effect of maintenance .
The
Braided Sleeve has the characteristics of corrosion resistance, rust resistance, and shielding of electrostatic induction, which can well ensure the working efficiency of the car's power circuit. The aged braided sleeve can ensure that the wiring harness does not absorb dust, making the engine cover wiring harness bright as new mouth.
