PVC wire transparent hose molding process and formula

PVC transparent plastic hose, PVC plastic hose, pvc wire transparent hose with high pressure resistance, tensile resistance, oil resistance, acid and alkali resistance and good transparency, pvc wire transparent hose is widely used in automobiles, ships, machinery, Petroleum and chemical industries and other industries can pump various liquids and gases.
 1, PVC wire transparent hose molding principle

PVC plastic hose refers to a hose made from a pvc, glass fiber, metal wire, etc., as a middle sandwich of a hose. The key to its formation is the weaving of the web. According to the weaving method of the fabric, we can divide the weaving inside the die and the weaving outside the die. At present, most of the foreign countries use the outer winding weaving method, this method can produce the ideal PVC wire transparent hose.

 2, PVC wire transparent hose reference formula

PVC 50, DOP 10, DOA 10, chlorinated paraffin 15, organic tin 0.6, PE wax 0.2, stearic acid 0.1

3, PVC steel transparent hose process

Ingredients → Mix granulation → extruder No. 1 Extrusion of inner wall tube → Cooling → Weaving → No. II extruder Extruded outer layer → Cooling → Traction → Illumination inspection → Coiling → Packaging → Finished product.

 4, PVC wire transparent hose molding equipment and device design

Pvc wire transparent hose molding equipment, from the main extruder, vice extruder, head, air-cooled device, weaving device and traction, light inspection, coiling device.

§ Primary and secondary extruders

PVC wire transparent hose specifications are generally in the Φl2-Φ50mm range, so use Φ45mm, the extruder can be, extrusion random screw length to diameter ratio L / D = 20, divided into four sections of heating, stepless speed, two machine center High are l00mm.

§ Head (die)

The design of the head depends on the size of the pvc wire transparent hose. The design is reasonable or not, which directly influences the molding quality of the pipe.

§ Weaving device

The weaving shuttle and left and right weft-knitting shuttles and fixed-axis components can be used to design one or more sets of weaving devices. Each group of weaving devices can also design multiple right and left weft threads and multiple diameter lines. The left and right shuttles are respectively installed at both ends. Each bobbin can be equipped with 1 to 5 bobbin thread reels. When the drive shaft rotates the left and right shuttles, the upper bobbin thread is wound around the continuously extruded PVC wire. Transparent hose on the inner wall of the tube, according to the extrusion speed of the blank and the required degree of weaving network to determine the rotation speed of the shuttle and the number of bobbin thread, generally there is a l-2 per transfer A single core roll can provide a significant enhancement. The warp threads are penetrated by the meridian holes on the fixed axis without rotation.

§ Cooling air ring

Pvc wire transparent hose is often water-cooled, but considering that the billet from the No. 1 die will immediately enter the No. II die head to cover the outer plastic, so the No. 1 die can not be extruded Cool with water and cool with air ring. Otherwise, the water on the tube blank will produce air bubbles and affect the product quality. The air ring is cooled. The air volume is controlled at Q = 1500m3/hr, using a double-lip air ring.

§ Traction device

The traction device is the same as the traction of the ordinary hose. In order to ensure the regularity of the pvc wire transparent hose reticular fabric, the traction and the machine can be linked with the weaving device.

§ Optical inspection and winder

The light box is used to test the uniformity of the wall thickness of the pvc wire transparent hose and the rules of the weaving mesh. The 60 watt fluorescent lamp can be used in a box with a glass. The winding device adopts a friction clutch to keep the winding. tension.

The quality of the pvc wire transparent hose produced by this method is stable and reliable, and the production cost is greatly reduced. The price is only about 1/3 to 1/2 of the rubber pipe, and it is transparent, oil-resistant, flame-retardant, weight, life, etc. The performance is much better than the rubber tube. Therefore, it has promotion value in actual production.
