Problems solved by technology

[0002] With the development of science and technology and the progress of society, more and more plastic particles are used, such as household appliances, clothes, vehicles, and medical fields. At present, most plastic particles use new high-pressure polyethylene, which leads to high manufacturing costs. Conducive to environmental protection, so the cost of use will also increase

Embodiment 1

[0029] Cleaning masterbatch: prepare and classify the recycled masterbatch; dry masterbatch: dehydrate the masterbatch first, and then dry it, which can improve the drying efficiency; smash the masterbatch: then put the masterbatch into the In the crushing device, the masterbatch is crushed; processing of auxiliary materials: the polymer resin must be sieved before use, and the powdered additives with coarse particles or easy to agglomerate are first refined with a plasticizer; formula weighing: Raw materials should first estimate the feeding amount according to the equipment volume and feeding coefficient, and accurately weigh according to the feeding amount. The weighing must be accurate, otherwise the quality of the product will be unstable; processing and kneading: add raw materials with a good ratio into a high-speed kneader for mixing Kneading; extruding material: plastic pellets are processed by twin-screw extruder.

Embodiment 2

[0031] Cleaning masterbatch: Prepare and classify the recycled masterbatch. Generally, the masterbatch can be cleaned with clean water. The masterbatch with oil stains can be cleaned with cleaning agent. For the masterbatch with severe staining, it needs to be cleaned with caustic soda (NaOH). color; drying masterbatch: dehydrate the masterbatch first, and then dry it, which can improve the drying efficiency; break the masterbatch: then put the masterbatch into the crushing device to crush the masterbatch; auxiliary materials Processing: Polymer resin must be sieved before use, powdered additives with coarse particles or easy to agglomerate are first refined with plasticizer; formula weighing: raw materials should first be estimated according to equipment volume and feeding coefficient Quantity, accurate weighing according to the feeding amount, the weighing must be accurate, otherwise the quality of the product will be unstable; processing and kneading: adding raw materials wi...

Embodiment 3

[0033] Cleaning masterbatch: Prepare and classify the recycled masterbatch. Generally, the masterbatch can be cleaned with clean water. The masterbatch with oil stains can be cleaned with cleaning agent. For the masterbatch with severe staining, it needs to be cleaned with caustic soda (NaOH). color; drying masterbatch: dehydrate the masterbatch first, and then dry it, which can improve the drying efficiency; break the masterbatch: then put the masterbatch into the crushing device to crush the masterbatch; auxiliary materials Processing: Polymer resin must be sieved before use. Powdered polyvinyl chloride is generally sieved with a 40-mesh sieve. Granular polyethylene or polypropylene is sieved. It can be sieved with a fine wire mesh slightly larger than the particle size of the resin. Coarse or easily agglomerated powdered additives are first refined with a plasticizer; formula weighing: the raw material should first estimate the feeding amount according to the equipment volum...

Abstract

The invention relates to the technical field of plastic particles, in particular to a production process of plastic particles. The production process comprises the following steps that master batchesare collected, wherein the recycled master batches are prepared to be classified and cleaned; the master batches are dried, wherein the master batches are firstly dewatered and then dried, and dryingefficiency can be improved; the master batches are smashed, wherein the master batches are placed into a smashing device to be smashed; and accessories are treated, wherein high polymer resin must besieved before use, and powder additives which are thick in particle or are prone to being caked are firstly subjected to pulping through a plasticizer. According to the plastic particles produced through the production process, the adopted master batches are recycled waste plastic products, and therefore environment protection is facilitated, and meanwhile the production cost of the plastic particles is reduced. Thus, the use cost of the plastic particles is reduced, and the problems that existing plastic particles are most prepared by new high pressure polyethylene, consequently, the preparation cost is high, operation is adverse to environment protection, and the use cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of plastic granules, in particular to a production process of plastic granules. Background technique [0002] With the development of science and technology and the progress of society, more and more plastic particles are used, such as household appliances, clothes, vehicles, and medical fields. At present, most plastic particles use new high-pressure polyethylene, which leads to high manufacturing costs. Conducive to environmental protection, thereby the cost of use will also increase thereupon. Contents of the invention [0003] The purpose of the present invention is to provide a plastic granule production process to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a production process of plastic granules, comprising the following steps: [0005] S1. Clean the masterb...
