Abstract

The invention relates to a PVC tube, in particular to a PVC anti-freezing tube which mainly comprises a tube body, sponge is arranged on the tube body, steel balls are arranged in the sponge, and the sponge is sleeved with a PVC tube sleeve. The PVC anti-freezing tube is simple in structure and reasonable in design, and a hollow layer is filled with the sponge, so that the heat preservation effect of the tube body is good, and the tube body is not prone to be frozen and not prone to cracking. Under the action of the steel balls, the gap existing between the external tube sleeve and the tube body is reduced, the external PVC tube sleeve is prevented from being fractured, and therefore the service life of the PVC anti-freezing tube is prolonged.

Description

Technical field: [0001] The invention relates to a PVC pipe, in particular to an antifreeze PVC pipe. Background technique: [0002] PVC (full name Polyvinylchlorid), the main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC pipe (PVC-U pipe) rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and is extruded by hot pressing. It is the earliest plastic pipe t...
