Abstract
The present invention discloses a double-wall hard PVC pipe. Said drain pipe is composed of internal wall and external wall, its internal wall is made of waste and old PVC material, and its external wall is made of full-new PVC material. Its surface is smooth, bright and white, beautiful and durable, its inner wall is smooth, it not only reduces production cost, but also can eliminate the environmental pollution resulted from waste and old PVC products. As compared with similar product its cost can be reduced by 30%-50%.
Description
The present invention relates to a kind of hard polyvinyl-chloride drainage pipe with composite wall.
At present, hard polyvinyl-chloride drainage pipe of the prior art generally all is to adopt brand-new pvc material to be made, though the hard polyvinyl-chloride drainage pipe that the brand-new pvc material of this employing is made has pure white light, attractive and durable, the advantage of inner wall smooth, but owing to be to adopt brand-new pvc material to make, therefore exist the higher shortcoming of cost of manufacture, particularly after drainpipe that the brand-new pvc material of this employing is made is with old or damage, generally all it is passed into disuse, no longer it is reclaimed and be made into the drainpipe use again, the article that this outcast waste polyvinyl chloride drainpipe or other outcast employing PVC pvc material are made have caused very big pollution to environment.
The objective of the invention is: a kind of advantage that can keep the pure white light in brand-new hard polyvinyl-chloride drainage pipe surface, attractive and durable, inner wall smooth is provided, can reduces production costs, reduce the hard polyvinyl-chloride drainage pipe with composite wall of waste polyvinyl chloride article environmental pollution again.
The present invention is achieved in that drainpipe of the present invention forms by inner and outer wall is two-layer, and the inwall of drainpipe adopts waste and old pvc material to make, and the outer wall of drainpipe adopts brand-new pvc material to be made.
Owing to adopted technique scheme, the present invention compares with existing hard polyvinyl-chloride drainage pipe, the present invention is except the advantage that has kept the pure white light in brand-new hard polyvinyl-chloride drainage pipe surface, attractive and durable, inner wall smooth, owing to adopted waste and old pvc material, not only reduce production cost, also reduced waste polyvinyl chloride article pollution on the environment.The present invention compared with similar products, can reduce cost 30%～50%, and, product of the present invention verifies as qualified products through plastic products product quality supervision and inspection station, Guizhou Province and Guiyang Administration of Quality and Technology Supervision, and its security of products, reliability, practicality all meet the requirement of like product.
Accompanying drawing 1 is a structural representation of the present invention.
Embodiments of the invention: collect various discarded PVC polrvinyl chloride products, through selecting, clean, broken, behind the abrasive dust, carry out granulation by the prilling of plastic products again and get waste and old pvc material, brand-new pvc material can directly use the finished-product material of selling on the market, caliber requirement according to drainpipe, design and produce out earlier double stack mold routinely, then under the condition of high temperature, add new and old two kinds of pvc materials, the inwall (2) that is drainpipe adopts waste and old pvc material, the outer wall of drainpipe (1) adopts brand-new pvc material, the inside and outside two-layer of drainpipe extruded simultaneously, make it closely to merge, can make hard polyvinyl-chloride drainage pipe with composite wall finished product of the present invention like this.
Claims (1)
1, a kind of hard polyvinyl-chloride drainage pipe with composite wall is characterized in that: drainpipe is formed by inner and outer wall is two-layer, and the inwall of drainpipe adopts waste and old pvc material, and the outer wall of drainpipe adopts brand-new pvc material.
