The PPR fiberglass pipe making machine is composed of two extruders co-extrusion, a mold, a vacuum water tank, a spray water tank, a tractor, a cutting machine, and a discharge frame.The PPR pipe production line produce the glass fiber reinforced PP-R (FR/PP-R) pipes are high-performance pipes produced at low temperature and high speed through special processes and equipment using multi-layer co-extrusion.The fiber glass pipe advantages:1. The linear expansion coefficient is only about 20~30% of ordinary PP-R products; it completely solves the problem of plastic pipe expansion and contraction.2. The rigidity of the pipe is increased to prevent the pipe from sagging, and at the same time, the density and number of fixed support points are reduced, thereby reducing the overall cost of the project.3. The pressure rating is higher, and the service life is longer under the usual design tremor.4. Better high temperature resistance and obvious energy saving and consumption reduction effect; FR/PP-R is used in hot water system, and the normal use temperature can reach 95~100℃, which not only increases the temperature of the medium used, but also reduces the heat preservation material Thickness, its overall cost is lower.5. Large water flow: Under the same level of pressure, the wall thickness of FR/PP-R pipe is thin, which increases the inner diameter of the pipe, thereby increasing the water flow (increase by 20%).6. The oxygen permeability problem of the pipeline is solved, and the inner surface directly in contact with water has good sealing performance and will not form sphagnum moss. The composition of the middle layer of the FR/PP-R pipe reinforced by glass fiber completely isolates the outside air from penetrating into the pipe, thereby inhibiting the growth of algae and keeping the water quality fresh and pure

PVC corner bead production line also called PVC tile trim extrusion machine consists of a conical twin-screw extruder, double head die, vacuum setting platform, double tractor, double punch machine, double punching die, double cutting machine, and double-station unloading rack.PVC corner angle is a new type of decoration material for the construction of wall corners, door side strips and window corners. Its strength and toughness have enabled people to safely replace steel, wood, aluminum and other traditional building materials. The current corner construction process in China has followed decades of traditional construction methods, which are very inefficient and cumbersome, and the corners of the completed buildings are very vulnerable to damage during use: on the one hand, it is due to the contact frequency of the corners. On the other hand, because the corners are not strong enough, and the damaged external corners are not repaired by maintenance personnel, the quality of the project is reduced, especially the corners of doors and windows. Family houses generally use edge wrapping, but this This kind of decoration method not only wastes a lot of wood, but also wastes a lot of money for the decoration, causing a lot of pollution. At present, the internationally used PVC corner protectors are made of high-strength polyvinyl chloride raw materials, which have the advantages of environmental protection and corrosion resistance.
