Embodiment 1

[0020] A new carat tube preparation process, the specific steps are as follows:

[0021] Step 1, mixing: select qualified raw materials, raw materials include HDPE resin, LDPE resin and color masterbatch, HDPE resin, LDPE resin and color masterbatch account for 78%, 0 and 22% of the total weight by mass, and the raw materials are according to Put the proportion into the mixing unit to mix evenly and dry, the drying time is 30 minutes, and the drying temperature is 35 degrees Celsius;

[0022] Step 2, extruding: sending the dried raw materials to the extruder, the barrel temperature of the extruder is 154 degrees Celsius, and the mold temperature of the extruder is 195 degrees Celsius;

[0023] Step 3, heating: the mold roller is heated by infrared high-frequency through an infrared heating device, and the corrugated pipe is passed through the pipe material, and the molten pipe material is coated on the outside of the bellows to form a reinforcing rib;

[0024] Step 4, Winding...

Abstract

The invention discloses a novel clavulanate pipe preparation process. The process comprises the following steps that 1, materials are mixed; 2, extruding is carried out; 3, heating is carried out; 4,winding is carried out; 5, cooling is carried out; 6, shaping is carried out, the sizes of a socket and a bellmouth of a pipe are processed to a standard size, ports of the pipes are trimmed, so thatthe appearance of the pipe is smooth and regular; and 7, inspection and storage are carried out. The preparation process is reasonable in steps and good in continuity, a flat belt and an O-shaped beltare uniformly wound on the heated roller mold in a preset position, the quality of a pipe fusion seam is guaranteed after cooling, and continuous winding forming is carried out on the mold; water cooling, air cooling or combination of the water cooling and the air cooling is selected according to actual conditions, so that the crystallization of the product is more compact and uniform, the infrared heating device is adopted for heating, and the production safety is improved; and reinforcing ribs are designed in the product, so that the external pressure resistance of the whole pipe is improved, and the use effect is good.

Description

technical field [0001] The invention relates to the field of carat tubes, in particular to a novel preparation process for carat tubes. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are extruded in the pipe making machine by the "plastic" method. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing and convenient construction, it has been more and more widely used in construction projects. It is mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction, etc. [0003] In the known technology, there are many kinds of plastic pipes. Generally, the prepared plastic materials are used to make them through a plastic pipe extruder. A plastic pipe. The carat t...
