Structure And Characteristics Of PVC Aluminium Foil Composite Hose
Structure and characteristics of PVC aluminium foil composite hose
(1) PVC composite material made of tin foil and process
(2) according to the needs of telescopic adjustable, lightweight, easy construction.
(3) durable and sealed.
Dust hose usually nylon, mesh cloth, polyester, thermoplastic or PVC material. Generally with retractable design, with high temperature, oleic acid, flame retardant, insulation, free of joint, lightweight and other characteristics.
Defining a dust hose generally involves the following parameters:
The distance (meters) that a medium can pass per unit time (SEC). Better ventilation rate up to 30 meters per second.
The temperature range is -40 to +120, and the instantaneous temperature is +150 centigrade.
Bending radius is the radius of an inner circle that a hose can bend but does not damage or shorten its service life. When used, if the bending radius is less than R, the hose will probably kink.
The common bending radius is 1 times the inner diameter of the hose.
Bore, weight, and pressure bore, the inner diameter and outer diameter of a hose, usually expressed in millimeters (mm).
Weight, usually measured in kilograms per meter.
Dust hose generally allows only conditions not higher than 0.05Mpa low pressure environment, special circumstances will need to bear a certain negative pressure, that is, vacuum.
