The rubber and plastic products industry is a traditional manufacturing industry in China, occupying an important position in the world industry. There are many types of rubber and plastic products, and their widespread use in aerospace, civilian and other fields has irreplaceable strategic significance. However, these traditional manufacturing industries are also major contributors to environmental pollution. The average proportion of odor/foul odor complaints in the rubber and plastic products industry from 2018 to 2020 was 8.3%. In the past three years, the number and proportion of complaints have decreased, from 13749 in 2018 to 6773 in 2020, and the proportion of complaints has decreased from 9.0% to 6.9%. In 2020, 78% of complaints in the rubber and plastic products industry came from the plastic products industry, and 22% came from the rubber products industry. The main reason for complaints about odors/odors caused by the rubber and plastic products industry is insufficient source control measures, and currently there are insufficient measures to replace odorless raw materials at the source; Secondly, the overall efficiency of exhaust gas collection is low, and the problem of unorganized emissions is prominent; The third issue is improper selection of governance techniques, with prominent problems such as coping with governance, blind governance, and ineffective governance.

Especially in the production of plastic products, stabilizers, antioxidants, light stabilizers, etc. need to be added, which will decompose and produce a large amount of toxic and irritating organic waste gas during plastic melting and drawing; In addition, some manufacturers use incineration methods to dispose of waste such as old screens and sorted plastic waste, causing a large amount of toxic smoke to spread. The industrial waste gas emitted during the production process produces gaseous organic pollutants such as hydrocarbons and benzene derivatives. These pollutants have a peculiar odor and often cause adverse sensory effects when discharged into the ambient air, while also posing significant harm to human health.

The composition of exhaust gas is complex and can be roughly divided into the following categories:

Sulfides: H2S, SO2, thiols, sulfides

Dust: fillers such as carbon black

Chloride: amides, indoles;

Hydrocarbons: alkanes, alkenes, alkynes, aromatic hydrocarbons

Organic solvents: gasoline, benzene, toluene, xylene, ethyl acetate, chlorobenzene

Other organic compounds, including alcohols, phenols, aldehydes, ketones, and organic acids.

Characteristics of exhaust emissions:

The rubber and plastic products industry has a large amount of exhaust emissions and complex components, among which the odorous components cause particularly serious pollution to the factory area and surrounding environment.

Recommended monitoring equipment:

Germany AIRSENSE portable electronic nose odor monitoring device, Germany AIRSENSE online odor monitoring device, independently developed portable/online multi-component gas monitoring device, etc

Reason for selection:

The instrument runs stably, the sensor performance is good, the software comes with multiple algorithms for accurate detection results, and the product configuration is flexible to meet various needs.
