Abstract
The invention provides a method or preparing plastic seamless air duct, which is used for aeration and ventilating in mine and tunnel. Putting chemical fiber gaze duct on finish mold of plastic-coated special mode, the plasticized granulate coating the internal and external surface of circular duct blank at a certain temperature with high molecular material with main body being PVC. The plastic air duct is characterized by strong intensity of coating layer, small wind resistance, high effective air quantity, and withstanding high voltage as large as 6000-6500 Pa.
Description
One, technical field
The present invention relates to a kind of manufacture method that is used for the plastic seam-free air-duct of down-hole ventilations such as mine, Tunnel Engineering, particularly be suitable for the manufacture method of the plastic seam-free air-duct of remote, the big air quantity ventilation in down-hole.
Two, background technology
At present, China is used for that down-hole, mine airy ventilating duct mostly is rubber leather or the plastics leather is made, and on manufacture method, adopt calendering formation, be generally the plain cloth shape, when making air duct, must get and vertically sew up or bonding and splicing, therefore, there is one or several longitudinal joint inevitably in the ventilating duct of making, and these longitudinal joints are as using bonding way, then easily peel off, have influence on intensity because of the coating of rubber leather or plastics leather; As the ventilating duct air leak rate of air curtain being increased with sewing up mode, make the pinprick that is brought, also have a strong impact on ventilating duct intensity simultaneously, therefore, longitudinal joint is the strength weak link of whole piece ventilating duct, its existence has determined that the intensity of ventilating duct is low.Simultaneously, the product that calendering technology is made also exists coating easily to peel off, and work-ing life is short.Moreover, China recent years, along with the raising of coal mine machinery production degree, developed New-type local blower, apply as convection rotary type portable blower, diagonal flow type portable blower etc., also more and more higher to its ventilating duct processing requirement that matches, require ventilating duct diameter 800-1000MM, wind supply quantity is 500 cubic metres/minute, pressure 5000-5500Pa, (existing originally ventilating duct generally only reaches about 3000Pa), it is remote that air supplying distance reaches 1500-2200 rice.Because existing air duct quality index does not reach the supporting requirement of present import secondary fan, use the conventional air duct of introduction blower fan adapted as tafelberg mineral bureau, ventilating duct occurs and tore phenomenon, have a strong impact on down-hole ventilation engineering.
Three, summary of the invention
At the present conventional ventilating duct of China, no matter all can not match with its corresponding New-type local blower at aspects such as pressure, air quantity, diameters, the purpose of this invention is to provide a kind ofly have withstand voltage height, wind supply quantity is big, air leak rate of air curtain is little, the manufacture method of the plastic seam-free air-duct of the remote down-hole ventilation of long service life.
The main raw material of plastic seam-free air-duct of the present invention, form by polyvinyl chloride (PVC) RESINS, softening agent, thermo-stabilizer, static inhibitor, fire retardant, lubricant, pigment, filler etc., it is characterized in that technical recipe by weight percent ratio be: its base-material PVC (polyvinyl chloride (PVC) RESINS) 20-30%; Softening agent (as petroleum phenol hydrocarbon, dibutylester, dibutyl ester etc.) 25-35%; Thermo-stabilizer (recombiner) 1-3%; Static inhibitor (SH-105) 01.8-2%; Fire retardant (antimonous oxide) 8-12%; Lubricant 0.5-1.5%; Pigment (carbon black) 1-2%; Filler (lime carbonate) 20-30%.Its manufacturing step: 1. granulation: with the polyvinyl chloride (PVC) RESINS is base-material, adds auxiliary agents such as quantitative softening agent, thermo-stabilizer, static inhibitor, fire retardant, through kneading the stirring extruding pelletization, makes pellet; 2. the tube base is weaved: chemical fibre silk (yarn) weaves the circular cylinder base on special loom; 9. be coated with molded: earlier with pellet preheating under 90-110 ℃ temperature, with the tube base of weaving, place on the mouth mould of the particular manufacturing craft of using plastic-coated, the head temperature of mouth mould and forcing machine is controlled at 160-190 ℃, the plastifying pellet evenly applies the macromolecular material of one deck based on the PVC plastics on the inside and outside two sides of circular cylinder base, through the spray water cooling, then through rolling, installation suspension ring accessory, examination and test of products warehouse-in.
Adopt advantageous effect of the present invention as follows:
(1), bulk strength, withstand voltage height, the present invention adopt the disposable plastic spraying in innner and outer sides at chemical fibre silk (yarn) tube base, therefore, the bulk strength of air duct and coating adhesive strength height, anti-blast is big, reach 6000---6500Pa, and having general air duct now about 3000Pa, diameter reaches more than the 1000MM, (and existing air duct diameter is at 600-800mm).(2), performance of ventilating is good.Tube of the present invention base adopts high-intensity chemical fibre silk (yarn) to weave out on special loom, air duct does not vertically have seam, windage is little, air leak rate of air curtain is low, effective of wind amount rate up to more than 91%, air quantity is big.(3), solved the problem that high-power fanner lacks big blast, the supporting ventilating duct of major diameter.Technical indicators such as the surface resistivity of the high withstand voltage two-sided plastic-coated seam-free air-duct of the present invention and flame retardant properties meet Ministry of Coal Industry's required standard, applying of this product, solve the current novel high-power secondary fan that is promoting of China and do not had the supporting ventilating duct problem of ideal, improve the safe reliability of down-hole, mine ventilation, guaranteed mine and miner's security of the lives and property.
