Lisson high performance composite tube
Lisson composite hose is a special packaging container that occupies an important position in the packaging field. The so-called composite hose is a 'cylindrical packaging container made of flexible material, which is folded and sealed to form a tube barrel and one end is equipped with a nozzle. After squeezing, the content is squeezed out of the nozzle.' This is my country The definition stipulated in the packaging standard 'Packaging General Terms'.
Since the French used tin to make the first hose for packaging paints in 1840, tin-clad lead pipes appeared in the First World War, and aluminum pipes appeared in 1948. In the past, the soft metals used in traditional hose packaging, such as tin, lead, aluminum, etc., have the disadvantages of not being corrosion-resistant and heavy in quality. Recently, it has been gradually replaced by plastic hoses. In 1950, Switzerland invented a plastic hose made of LDPE. Because a hose made of a single plastic has weak anti-permeability, it is not suitable for packaging that requires good airtightness.
In the 1960s, a composite hose composed of multiple materials appeared in the world. The composite hose combines the advantages of metal and plastic, and has good barrier properties, corrosion resistance, and rupture resistance. Moreover, it is very popular because of its low cost and beautiful appearance. my country began to develop plastic composite hoses in 1972. In the past 30 years, it has developed rapidly, and many plastic composite hose production lines have been introduced. At present, the United States consumes 10 plastic composite hoses per person and 12 per person in Europe. In 1983, there were eleven toothpaste factories and cosmetics factories in China that used plastic composite tube packaging. my country's current annual production volume has reached 1.5 billion composite hoses.
In the 1990s, composite hoses began to be used for industrial fluid transmission, breaking the original limitations and becoming more and more widely used.
The definition of composite hoses is gradually generalized. The composite hoses produced by various manufacturers diversify their products according to different needs.
Composite hoses are expensive, high temperature, flammable, explosive, corrosive, and environmentally polluting liquid gases, composite hoses are resistant to oil and chemicals. Whether it is corrosive sulfuric acid, nitric acid, flammable and explosive solvents, composite hoses have excellent performance.
The composite hose is made of a multi-layer sealing structure of multiple materials. It still has good resistance to rupture and leakage in the harshest environment. It will not burst suddenly. It can easily handle gasoline, diesel, crude oil, and a variety of chemical liquids. Transmission work, even in cold weather can still maintain high flexibility.
Light weight, strong toughness, easy handling, soft tube body, flexible use, high temperature resistance, low temperature resistance, anti-aging, non-deformation, corrosion resistance, exposed inner spiral metal and special inner layer, with reliable electrostatic dissipation performance.
The hose body is composed of a multi-layer functional polymer film and a synthetic fiber fabric reinforcement layer, and two layers of spiral metal wires are wound firmly inside and outside.
The general structure is as follows.
Inner spiral steel wire: usually stainless steel, galvanized steel, aluminum alloy, polypropylene or TEFLON coated steel wire;
Outer spiral steel wire: basically use stainless steel or galvanized steel;
Inner lining: Select Teflon Polietilene Nylon PET and other functional films according to the characteristics of the conveying material, and use proprietary technology to compound the hose to have a wide range of liquid-resistant sealing performance
Reinforcement layer and anti-aging outer layer: The reinforcement layer provides the pressure resistance of the hose. The outer layer of the hose adopts an anti-wear and anti-aging colored outer layer.
The domestic composite hose market is actively developing. With the maturity of composite hose technology, the development of composite hose has really reached an accelerated stage. At the 2009 Guangzhou International Paint and Coatings Exhibition, it has not been seen that it can replace metal hoses and hoses. Composite hose of rubber hose.
Guangzhou Lisson Plastic Co.,Ltd. Aluminum-plastic composite hoses are widely used in toothpaste, jam, paint, shoe polish, food, adhesives, milk, jam, flavoring paste, cosmetics, adhesives, shoe polish, pigments and hair dyes. Product packaging.
