Q:What are the characteristics, properties and uses of PVC plastics?
PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounted for about 2/3 of the market, soft PVC accounted for 1/3. Soft PVC is generally used for flooring, ceiling and leather surface, but because the soft PVC contains softening agent (this is the difference between soft and hard PVC PVC), crisp, not easy to save, so the range of use is limited. The hard PVC does not contain softener, therefore, the utility model has the advantages of good flexibility, easy molding, uneasy brittleness, no poison, no pollution and long storage time, so the utility model has great development and application value. The essence of PVC is a kind of vacuum blister film. It is used in the surface packing of various panels, so it is also called decorative film and adhesive film. It is applied to many fields such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, as well as other small range of applications.
Q:The difference between the hot melt connection and connection to electricity
Electric melting needs electric melting pipe fittings, copper wire inside, copper wire electrify, pipe inner wall and pipe outer wall are heated and melted and bonded in one piece. Hot melt is the cross section of pipe material heated, then butt joint
Q:The difference between PP-R aluminum pipe and PP-R pure plastic pipe
From the aging resistance performance, aluminum pipe stable molecular structure inner layer outer layer PE apart, allowed to join the enough anti light, anti oxygen stabilizer and does not affect the inner health water contact; PE molecular structure is stable, but the single structure is not conducive to the addition of stabilizer is easy to cause two pollution water pipe: PP-R tube containing tertiary carbon atom most unstable, vulnerable to light, oxygen and impurities and aging.
Q:What is the plastic pipe joint of water supply pipes?
If you need to change or you need to connect a thick tube tube diameter hoop, if you want to separate the two pipes to three, if you want to connect to connect pipe can rotate joint.
Q:What tools and methods are needed for the installation of plastic hoses and steel tubes?
Because of the linear expansion of PVC - U drainage pipe, the temperature expansion is larger. In the installation of drainage risers. To install expansion joints, but how to install, and what part of the installation, the construction unit is notVery clear. At the same time in the construction of cross branch often is not properly installed or not installed bellows expansion joint, and in accordance with the specifications, drainage cross branch, stem straight pipe, ventilation pipe, circular ventilation tube apparatus and ventilation pipe on the confluence confluence no greater than 2 m, should be set expansion joints, and horizontal drainage the branch should set up special expansion joint. And the maximum spacing of retractable joints shall not exceed 4 M.
Q:PSP plastic steel composite pressure pipe has several ways of connecting
The pipe wall is smooth, the fluid resistance is small, and the scale is not fouling. Under the same pipe diameter and pressure, the head loss is 30% lower than that of the metal pipe, and larger transmission flow can be obtainedConnection: the product adopts double hot melt connection, no leakage.
Q:What are the differences between electrofusion welding, hot melt welding and welding connection?
Hot melt is to use materials for heating and melting of special equipment, and even after the material is cooled. The hot melt pipes used in the project are all hot melt, and the construction is convenient and economical;
Q:Plastic pipe fittings are not GB?
Plastic fittings are of national standard.Plastic pipes are usually made of synthetic resins, that is, polyester as raw materials, adding stabilizers, lubricants, plasticizers, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering.
Q:Municipal water supply pipeline is a plastic pipe, then its matching valves and fittings are plastic?
General DN75 below the pipe diameter can be used plastic pipe fittings, DN150 and more of the majority of cast steel valves, pipe fittings, and its plastic pipe connection is mainly flange connection.
Q:What are the connecting modes of steel wire mesh and plastic composite pipes?
The connection of wire mesh frame and plastic composite pipe is made up of two kinds of electric heating welding and flange connection. Electric melting connection is a composite pipe socket to electrofusion fittings, make embedded electric heat wire on the surface of the heat pipe fitting.
