CPE rubber wire and cable high-speed extrusion production line

one. Introduction to Radiation Crosslinked CPE Rubber Wire and Cable

1.1. Introduction and uses of CPE materials:

Chlorinated polyethylene (CPE) is a synthetic rubber, and it is also the most cost-effective rubber; CPE has excellent mechanical strength and electrical insulation properties.

, heat-resistant aging, weather-resistant, oil-resistant, solvent-resistant, flame-resistant, impact-resistant, high-soft and excellent processability; CPE is widely used in profiles and seals; in electrical

The wire and cable industry is used to manufacture medium and low voltage insulation materials and sheath materials; the impact agents used in the profile industry are used in hard materials, such as Dalian Shide and Wuhuhai.

CPE is widely used in screw profiles; in the wire and cable industry, CPE is gradually replacing neoprene and chlorosulfonated polyethylene rubber with an unstoppable momentum, and

Partially replace natural rubber and ethylene-propylene rubber. Compared with neoprene, it is slightly inferior to neoprene in oil protection under the premise of complying with national standards, but

The price is only 12-13 of neoprene; compared with chlorosulfonated polyethylene rubber, all performance is comparable, but the price is only chlorosulfonated polyethylene rubber

12-23; Compared with natural rubber and ethylene-propylene rubber, although the insulation is inferior, it is still manufactured due to its excellent flame retardant resistance.

The best materials for medium and low voltage insulation and sheath, especially its low price, are incomparable to ethylene-propylene rubber.

1.2 Current status of radiation crosslinked CPE rubber wire and cable

Radiation crosslinked wires and cables have been widely used in China, such as overhead cables, medium and low voltage transmission cables, various electrical wiring, etc.; Radiation crosslinked materials include

PE, EVA, PVC, etc., and mixtures of various polydilute hydrocarbon materials. CPE rubber is used for radiation crosslinking wires and cables, which started 10 years ago, but due to the material

Material formula technology, wire extrusion production technology and radiation technology have not been overcome, and industrial production is still not possible in China today;

In fact, it has not been effectively solved at present, and it is difficult to produce industrially. With known information, only one factory has the capacity to produce large-scale.

The annual production of finished cable products is more than 10 million meters.

1.3 Material formula technology and wire production and radiation technology

The production of qualified radiation crosslinked CPE rubber wire and cable products requires three technical support, these three major technologies are:

1.3.1. Material formula technology:

Material formula technology is the basis of radiation crosslinked CPE rubber wire and cable products. The current technology is completely based on cheap CPE as the base material and is equipped with various improvements.

Auxiliary materials for material and process performance are made into granular product rubber particles after reasonable mixing, which is completely different from traditional rubber materials.

Production method is a brand new rubber material production method. The rubber material production process is as follows:

Formula raw materials------Kneading and mixing----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

1.3.2. Wire extrusion production technology

Good CPE materials cannot obtain good products without good wire extrusion production technology. In order to improve the production quality and production efficiency of wires, radiation

The production of crosslinked CPE rubber wire and cable is completely different from the traditional rubber wire production method. The production process of the new method and the traditional method are as follows.:

New Method:

Rubber particles-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Traditional method:

Rubber strips----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Since the new method adopts particle feeding and no wire vulcanization, the production efficiency is greatly improved and the product failure rate is greatly reduced.

1.3.3. Wire radiation technology

Radiation technology is an indispensable factor in radiation crosslinked CPE rubber wire and cable products. This technology ensures high efficiency, high quality, low price and low consumption.

In the final stage of consumption, without this technology, there will be no qualified radiation crosslinking CPE rubber wire and cable products.

1.3.4 Radiation crosslinked CPE rubber wire and cable production process

Formula raw materials----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

--------Cooling and shaping--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The above method, except for the accelerator radiation crosslinking production process, other processes are exactly the same as the simplest PVC production. In other words, radiation crosslinking is used to create radiation.

Cross-linking CPE rubber wire and cables are to add a radiation cross-linking process to obtain high-quality rubber wire and cables based on the production of PVC wires.

1.3.4. Cost analysis and production equipment

1.3.4.1. Rubber material cost: Due to the advancement of formulation technology, the cost of rubber material is equivalent to that of ordinary 105℃ PVC material, that is, the material part is the same as that of ordinary

There is no significant increase in the cost of 105℃ PVC material ratio, about 13,000 yuan/ton;

1.3.4.2. Wire extrusion production cost: The radiation crosslinked wire extrusion production cost is equivalent to the ordinary PVC wire extrusion production cost, and there is no obvious increase in costs;

1.3.4.3. Radiation crosslinking production cost: Radiation crosslinking production cost. The radiation crosslinking production cost of wires of different specifications is different. The product specifications of the planned production

In other words, the radiation crosslinking production cost is about 0.02-0.5 yuan/meter; the overall cost, the total production cost of radiation crosslinking wire is just like that of ordinary 105℃ PVC.

The increase in the irradiation fee of 0.02-0.5 yuan per meter on the wire is insignificant.

1.3.4.4. Production equipment cost: Compared with ordinary PVC wire production lines, the production process requirements are stricter, so the equipment investment is relatively high, but Dongguan City Jingfeng

The CPE rubber wire and cable extrusion production line launched by Electrical Machinery Co., Ltd. is relatively cheap, and there is no need for a large amount of money to buy huge equipment and boilers, nor is there any need for

It occupies a large number of factories, and rubber material production and wire extrusion production also meet national environmental protection requirements.
