Production technology of special material for black communication optical cable outer sheath

Abstract

The invention belongs to the technical field of plastic material modification, and particularly relates to a production technology of a special material for a black communication optical cable outer sheath. The technological process comprises formulating of recipe, crashing and cleaning, batching and metering, high-speed mixing, centrifugal feeding, extrusion molding, cooling and air drying, cutting and screening, and air sending packaging. The production technology has the advantage that a continuous one-time technology is integrated with waste polyethylene film recovery processing and processing modification, and has the characteristics of high degree of automation, labor saving, no pollution, energy saving and emission reduction; with the production technology, the utilization efficiency of the waste polyethylene film and high product additional value can be effectively improved, the production technology is high in workability and operability and stable in quality, and the cost is saved by more than 20% compared with the production mode of two-step processing, thus the production technology solves the defects such as low efficiency, great energy consumption, low processing capability, high quality fluctuation, difficulty deep-processing modification and high comprehensive cost in the two-step processing method efficiently and reasonably in an environment-friendly manner.

Description

technical field [0001] The invention belongs to the technical field of plastic material modification, and in particular relates to a production process of a special material for the outer sheath of a black communication optical cable. Background technique [0002] With the improvement of industrial packaging requirements and the promotion of crop planting skills, the use of polyethylene packaging film and agricultural film is increasing. In 2012, domestic polyethylene film waste was as high as 500,000 tons. So much waste If the materials are not used rationally, it will inevitably cause environmental pollution and a huge waste of resources. With the advent of the information age, the advancement of the national fiber-to-the-home policy and the successive implementation of high-speed rail projects, the demand for special materials for the outer sheath of polyethylene optical cables is also increasing. In 2012, the use of special materials for the outer sheath of communicatio...

Problems solved by technology

In this recycling process, most of the recycling and granulation of waste polyethylene film is done by small individual workshops. They basically use crude coal-fired extruders for production, with backward processing technology, low efficiency and high pollution. , Product quality cannot be controlled, and there is no ability to process in large quantities

Because the coal-burning extruder cannot control the temperature, the material is often damaged by high temperature and the performance loss is serious. The raw material obtained by this processing method is then modified to produce polyethylene communication optical cable sheathing material. Consistency and processing stability are also difficult to guarantee
