PE tape production why there will be broken material phenomenon?

图片
  PE tape  is a polymer organic compound with a simple structure. In today's world, polymer composite materials with a wide range of applications are polymerized by ethylene. According to the density, they can be divided into high-density polyethylene, medium-density polyethylene and low-density polyethylene. Density polyethylene. Low-density polyethylene LDPE is relatively soft and is often used for high-pressure polymerization. High-density polyethylene materials have certain rigidity, hardness and mechanical strength, and are mostly used for low-pressure polymerization. High-density polyethylene materials can be used as containers, pipes and high-frequency electrical insulators. PE tape production environment requirements: Ordinary PE tape production environment is completed under the requirements of environmental pollution-free. The raw materials, production workshop and packaging workshop are all completed in a completely isolated production method, which ensures the high...

Chemical properties of PE tape materials

图片
  PE tape  is a kind of high molecular organic compound, and PE tape is often used in our daily life. PE is one of the commonly used polymer materials in daily life, used to make plastic bags, plastic films, milk barrels and other products. Polyethylene is resistant to a variety of organic solvents, resistant to a variety of alkali corrosion, but not oxidation, such as nitric acid, polyethylene will be oxidized in an oxidizing environment. Polyethylene can be regarded as transparent in the film state, but when it exists in the form of lumps, due to the large number of crystals inside, it will be opaque due to strong light scattering. The degree of crystallization of polyethylene is affected by the number of branches. The more branches, the harder it is to crystallize. The melting temperature of the crystal of PE tape material polyethylene is also affected by the number of branch chains. The distribution ranges from 90 degrees Celsius to 130 degrees Celsius. The more branch cha...

Method for identifying PE tape

图片
  In daily life, many   PE tapes   are often used to package products, but there are many types and names of packaging materials. When we need to use pe tape, what method should be used to identify it? PE film is widely used in the production of plastic bags, plastic films, and milk barrels. Its name is also called polyethylene film. It is resistant to a variety of organic solvents and acid and alkali corrosion, but it is not resistant to oxidizing acids, such as nitric acid. Polyethylene will be oxidized in an oxidizing environment. Polyethylene can be considered transparent in the state of a film, but when it exists in a block shape, there will be strong light scattering and opacity due to the large number of crystals inside. The degree of crystallization of polyethylene is affected by the number of branches. The more branches, the more difficult it is to crystallize. The melting temperature of polyethylene crystals is also affected by the number of branch chains, which...
