PVC pipe production line equipment function (1) raw materials are mixed: inside is PVC stabilizers, plasticizers, antioxidants and other materials, in proportion, the process has joined the high-speed mixer, the materials and mechanical self-friction heating the material to the set process temperature, and then by cold mixing machine the material down to 40-50 degrees; so that you can put into a hopper of the extruder. (2) Extruder parts: The machine is equipped with dosing device drains, the extrusion amount of the feed amount matches pvc u drain, ensure stable extrusion products. Because of the characteristics of the tapered screw, feed zone with a larger diameter, the material and the shear rate of heat transfer area is relatively large, in favor of plastics materials, small metering section of the screw diameter, reducing heat transfer area and the melt shear rate, the melt can be extruded at lower temperatures. When the machine barrel screw is rotated to push the nose after plasticized PVC mix, so as to achieve compaction, melt-kneading homogenization; and venting, dehydration purposes. Charging device and screw drive with frequency control, can achieve synchronous speed (PVC pipe drainage - Advantages: 1. pipe surface hardness and excellent tensile strength, high safety factor pipeline 2. aging resistance, normal use. life expectancy up to 50 years. 3. The pipeline of inorganic acids, bases, salts and excellent corrosion resistance for industrial sewage and transportation. The drain pipe friction coefficient is small size, flow smoothly, clogging drains construction program, less maintenance work. 5. material oxygen index, with self-extinguishing it with soft water pipe, plastic blind ditch has become China Civil Engineering Construction (seepage, drainage) in three major product municipal sewer network depending on the size of the discharge pressure, the choice of arms bellows and straight wall tube straight wall pipe pressure bearing ability, can be used for large-scale drainage outfall pipes dedicated network. pvc u sewer drains _ _ double clear plastic from the Xiong Zan Pair of bright plastic products factory offer. road Zhiyuan, temper forward. Xiong Zan Pair of bright plastic products factory (1620231.707070.cn) aims to become and you win symbiosis, strategic partners to move forward, more determined to become a UPVC pipe The most influential business, and you leap together to success!
