Do you know the reason for the rust of PET braided sleeves?

With the rapid development of the spotlight industry, people's demand for products is getting higher and higher. PET braided sleeves gradually replace the bellows traditionally used in automobiles. It is a non-elastic sleeve made of polyester textiles. Lightweight, good flexibility, abrasion resistance, sound reduction, high cost performance and high performance. The introduction of PET braided sleeves is mainly because it has the advantages of bellows, which saves more indoor space than bellows, and makes up for the major deficiency that bellows are not easy to bend.

Therefore, for fields with high safety requirements such as automobiles, high-speed rail trains, and machinery and equipment manufacturing, stainless steel PET woven sleeves will be very popular. Because it can not only protect the wires and cables, but also bring a certain appearance effect, especially in the field of wire harnesses with irregular shapes, the open-mouth structure is more conducive to internal wire harness protection, reinstallation, maintenance and repair.

The operating temperature of PET stretchable woven mesh is -50~+150 degrees, the melting point is 250 degrees, and the flame retardant grade is ULVW-1.
PET telescopic woven mesh is newly woven with environmentally friendly wire drawing. The outer diameter of the wire is 0.2mm or 0.25mm. According to the customer's requirements, it is decided to use wire drawing or three wires. The larger the number of wires, the PET telescopic woven mesh is woven. It will be denser, and the expansion and contraction time gap will be smaller.
PET telescopic woven mesh has good elasticity, wear resistance and fire resistance, smooth surface, bright colors, weaving texture can be woven according to customer preferences, rich colors, so it is loved by many customers.
In fact, the application range of PET stretchable woven mesh is very wide. For example, the power cord on the computer and the monitor video cable of the speaker can be inserted into the PET stretchable woven mesh. The temperature of the power cord is reduced. If the power cord is short-circuited and catches fire, the PET stretchable woven mesh can also be flame-retardant, reducing the risk of fire and greatly enhancing product safety. It can also be used in vehicles, cables and wires.
Because the stainless steel PET Braided Sleeve is not easy to rust, but the surface will still be corroded after long-term use. It is mainly caused by chemical changes between metal materials and O2 in the air. Generally, the compounds formed on the surface of ordinary carbon steel will continue to oxidize, and the rusted area will gradually become larger, and even small holes will appear. Generally, in order to better protect the surface of carbon steel, paint or oxidation-resistant metal materials can be used for electroplating, but this is only a protective film. If the protective layer is damaged, the steel below will begin to rust.
In order to prevent further oxidation, the stainless steel plate has a uniform surface, and the natural gloss of the stainless steel plate surface can be seen through this ultra-thin oxide layer. If the surface is damaged, the steel surface will continue to repair itself with the air, thus forming a "passive film" to continue to play a protective effect.
The PET braided sleeve has the characteristics of corrosion resistance, rust resistance, shielding of electrostatic induction, and aging resistance, which can efficiently ensure the working efficiency of the car power circuit; the embrittled Pet Braided Sleeve can ensure that the wire harness does not absorb dust, and the engine cover wire harness Bright as new.
