Embodiment

[0023] Example: A method for identifying wear-resistant plastic particles

[0024] See attached figure 1 , follow these steps:

[0025] The first step, weighing: take a plastic particle and place it on a high-precision weighing tool, which is an electronic weighing instrument accurate to 0.1 gram, and weigh the plastic particle to obtain the plastic particle the quality of.

[0026] The second step, appearance identification: use the naked eye and / or a magnifying glass to check the external color, transparency, texture, and particle size of the plastic particles to be identified.

[0027] The third step, identification of strength and toughness: use the means of pulling, pressing and beating to sense the strength and toughness of the plastic particles.

[0028] The fourth step, density identification: put the plastic particles into the solution of water, industrial alcohol and industrial salt water respectively, and judge the density of the plastic particles by observing th...

Abstract

The invention relates to an identification method of an abrasion-resistant plastic particle. The method comprises the following steps: taking a plastic particle in a high-precision weighing tool and weighing the plastic particle to obtain the mass of the plastic particle; viewing exterior color, transparency, texture and particle size of the plastic particle to be identified through naked eyes and / or magnifying lenses; sensing strength and toughness of the plastic particle by using manners of pulling via hands, pressing and striking; respectively putting the plastic particle in a water solution, an industrial alcohol solution and an industrial salt water solution, and judging the density of the plastic particle by observing the suspension degree of the plastic particle; clamping the plastic particle over open fire by using a clamping tool and calcining the plastic particle for 1-5 seconds, then taking the combusted plastic particle away from the open fire, and judging elements in the plastic particle by observing the sustained combustion time and the combustion color of the plastic particle and combining the quality of the plastic particle.

Description

technical field [0001] The invention belongs to the field of plastics, and in particular relates to a method for identifying wear-resistant plastic particles. Background technique [0002] Definition of plastic (American Plastics Industry Association): mainly composed of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements, the finished product is solid, and it is a molten liquid during the manufacturing process, so it can be melted by heating. Apply pressure to make it flow, cool to make it solidify, and form various shapes. This huge and varied material group is called plastic. Plastic granules, as the name suggests, are made of plastic into granules. [0003] At present, there is no complete set of methods for identifying plastic particles. [0004] Therefore, proposing a method for identifying wear-resistant plastic particles is the subject of the present invention. Contents of the invention [0005] The main purpose of this application is t...
