PVC or PVC cover both the upper and lower overburden conveyor rubber prices, the best single plastic ≥0.8mm conveyor, PVG-type top and bottom cover layer are nitrile rubber and PVC conveyor belt and enterprise, single thickness of 1.5mm-4.5 mm. PVC conveyor transport inclination <16o, PVG conveyor belt transport inclination <20o, can be used in coal surface and underground transport. Joint performance with the whole flame retardant in accordance with strength and with a core structure, the use of mechanical fasteners to connect, its strength of the joint body with up to 60-80% of the nominal tensile strength. Using adhesive joints, its joint tensile strength of up to 90% of rated with body strength. Various forms of joint approach to meet the different needs of customers, ensure the safety of the delivery system and efficient operation retardant conveyor belt production process: dry mastication → → → mixing → parked close Lian Lian → hot rolling → → → vulcanization molding → packaging. And non-nylon conveyor frame differs layered nylon flame retardant conveyor belt after vulcanization production process to go through secondary stretching routine processing. There are two main secondary stretch stereotypes, one is under pressure within the mold cooling setting method (hereinafter referred to as mold shape), and the other is outside the mold cooling setting stretching method (hereinafter referred to as the outer mold stereotypes). The mold shape is simple and good styling effect. However, this method stereotypes consumption, low productivity. In contrast, although the outer mold shaping method to be more of a conveyor belt stretching device, but after using this method reliable product quality, high production efficiency, suitable for mass-scale production of the best conveyor, conveyor Hunan, Central Asia entire industrial belt by full industrial belt Ltd. Qingdao Central Asia. Qingdao entire industrial belt of Central Asia Ltd.
