Polyester is dacron, and the two are equivalent. The raw material of the national standard flat color lifting Belt is polyester silk, and the chemical property of Webbing Sling Belt is acid resistant and alkali resistant. Because polyester fibers contain ester bonds, they hydrolyze under alkaline conditions. The polyester fiber changes, the fiber becomes thinner, the fiber surface has concave, and the strength of fracture decreases, so the polyester lifting belt is not suitable for use in alkaline environment. Polypropylene white Webbing Sling Belt is not corroded by acid and alkali, so it is also called acid and alkali resistance Webbing Sling Belt, suitable for use in the environment of strengthening corrosion.
Flat lifting belt webbing
Acids are widely used in many industries and laboratories. Flat color lifting belt can resist organic acid and most inorganic acid, polyester fiber is resistant to weak acid, the raw material of its own color flat lifting belt is synthetic fiber derived from polyester spun by condensation of organic diacid and dialcohol. Here, the inorganic acids that polyester lifting belt cannot resist are concentrated acid and strong acid, which have strong corrosion properties. Such as: concentrated sulfuric acid, hydrochloric acid and so on.
The phenomenon of broken hoisting belt combination rigging appears in the process of use, I believe many people have also encountered this situation, but some friends will sew the broken hoisting belt by themselves and continue to use in order to save costs. This approach is certainly undesirable.
The lifting belt is broken
When weaving synthetic fiber lifting belt is composed of their industrial wire braiding, its bearing capacity is connected, but when synthetic fiber lifting belt after fracture has been damaged, virtually the whole ribbon pull pull damage to what extent this is our immeasurable, can not continue to use after sewing. The other is lifting belt after breakdown or damage, cannot use downgrade, because there is no specific lifting belt frayed or fracture after loading standard, can not accurately determine it can support multiple objects, in the fall, has once again break the goods directly when working party causing the damage or casualties incident will happen again, safety concerns have been hidden. We don't want to believe that. Therefore, the lifting belt should be replaced in time after fracture or wear.
The fracture or wear a lifting belt should be thrown away, if you compare the value of items, then you can use lifting band of small objects and so on, or complete a ribbon as a lifting wear pads, pad between the object edges and industrial lifting belt, lifting belt in order to protect the industry in force when being worn edges and corners, overall color hoisting belt can also play a role of the other in your hands.
