This product is mainly applicable to underground coal transportation can also be used to transport materials in metallurgy, chemical industry. Whole flame retardant PVC conveyor belt can be divided into type and PVG type. The upper and lower layers are covered with PVC type PVC plastic cover, single plastic ≥0.8mm; PVG-type cladding layer down are nitrile rubber and PVC and use, single thickness of 1.5mm-4.5mm. PVC conveyor transport inclination <16 °, PVG conveyor belt transport inclination <20 °, can be used in coal surface and underground transport. Mainly used in coal mine. The band features: body with no delamination, small elongation, impact resistance, tear resistance. Results can be divided according to the different type of PVC (plastic surface), PVG type (based on the increase in PVC attached rubber surface) with the whole flame retardant, execution MT914-2002 standards. ○ PVC flame retardant conveyor belt is suitable for material handling in dry conditions below 16 degrees of inclination. ○ PVG retardant conveyor belt for the following 20-degree angle moist material conveying water · 1, Model N / mm (tensile strength): Level 4 5 6 7 8 9 10 Model 680s 800s 1000s 1250s 1400s 1600s 1800s · 2, flame-retardant properties: (1) the number of roller mill: roller surface temperature of not more than 325 ℃. (2) torch burning: Full-thickness specimens to blowtorch flame no time average of less than 3.0S, to overlay an average of no more than 5.0S. (3) propane burner: lossless length greater than 250mm · 3, the safety performance: The conveyor belt has passed the flame test and static test and other tests, and received a certificate of coal safety signs and customer acceptance. This product uses the core as a whole with a reinforcing material, impregnated, coated hanging with excellent antistatic, flame-retardant properties of plasticized PVC material made later. . 4, the longest service life with the life of the body is determined by the following factors (1) by the warp and weft yarn and woven cotton cover with a dense core; (2) dip on specially formulated PVC material so between core and cover with plastic to achieve high adhesive strength; (3) specially formulated plastic cover; so that the belt body impact resistance, tear resistance, abrasion. 5, the mechanical properties: excellent mechanical properties retardant conveyor belt, can provide users with the longest service life of the installation and the economy. 6, the product structure: retardant conveyor belt with the overall core as a skeletal material, impregnated, coated hanging after having an excellent antistatic, flame-retardant properties of plasticized PVC material made.
