As an important medium for network communication and data transmission, optical fiber cable is inPower, communications, transportation, energy, etcplays an indispensable role. However, while the optical cable industry plays an important role in providing infrastructure such as communication to society, it is generated during its manufacturing processHazardous wasteNot to be overlooked!
Fiber optic cable industry, hazardous waste you don't know
In the production process of fiber optic cables,Drawing, coloring, sheathing and overmoldingwill generate a large amountHazardous wastethingsIf hazardous waste is not properly treated and managed, it may lead to serious environmental pollution and human harm. What are the main characteristics of these hazardous wastes?Look down!

How should these wastes be stored safely?
Tip 1: The first step in compliance – choosing the right packaging container
Packaging containers containing hazardous waste shallIntactwith no corrosion, contamination, damage, or other leakage risks. AndThe structure of the container must have a certain strengthto prevent deformation or breakage during transport and storage.

Tips2: The second step of compliance - accurate hazardous waste labeling
After hazardous waste is loaded, it is necessary to strictly follow the "Technical Specification for the Setting of Hazardous Waste Identification Signs (HJ 1276-2022)".Fill out and post the correct hazardous waste label.

tips3: The third step of compliance - zonal storage of hazardous waste
In order to prevent contamination of other wastes after the leakage of liquid glue, polymers in different states can be usedpartitionsto ensure the safety of hazardous waste storage.
Waste glue & alcohol waste:
Wrap the plastic drum tightly around the plastic drum on an impermeable tray and apply it when it is stored in the same place as other wastesCofferdams, fences, or visible pedestrian passages are zoned for isolation
Empty bottles of waste cleaning agent & empty barrels of waste engine oil:
Waste empty bottles and waste empty barrels should be packed in tons of bagsThe mouth of the bag must be tightly sealed

Waste is used to treat waste, and it is skillfully disposed of
The waste glue produced by the optical cable industry will undergo polymerization and solidification reaction during the storage process, and the longer the storage timeStrength and stiffnessalso the higher. Face this"Hard as steel".of polymers, how"Overcome rigidity with softness"., clever preprocessing?
Pre-treatment.
Configure a solvent.
The appropriate solvent is selected according to the composition and properties of the waste polymer, and the concentration of the dissolved solution is determined based on the amount of waste polymer and the proportion of the solvent.
Polymer is added.
The waste polymer is gradually added to the dissolved solution to ensure adequate dispersion and avoid clumping.
Promotes dissolution. Adjust the parameters such as temperature, stirring speed and time of the dissolved solution according to the actual situation to promote the dissolution of the polymer.
Separation and **.
After the polymer is completely dissolved, the polymer in the dissolved solution is separated from the solvent by filtration, centrifugation, evaporation and other methods.
Disposal link.
Incineration. The separated waste liquid is transferred to the incineration system through the waste liquid feed pipeline for high-temperature disposal, and the disposal exhaust gas emission meets the standard requirements.
