The State Administration of Work Safety has recently published the filing documents for eight major dangerous sources of hazardous chemicals, including the “Basic Characteristics of Major Hazardous Sources of Hazardous Chemicals,†and requires all hazardous chemical companies to use them from April 10, 2012 onwards. It is understood that these 8 kinds of instruments include the "Basic Characteristics of Major Hazardous Sources of Hazardous Chemicals", "Application Form for Filing of Major Hazardous Sources of Hazardous Chemicals", "Registration Form for Significant Hazard Sources of Hazardous Chemicals," and "Significant Hazard of Hazardous Chemicals". Source Record Notification, Application Form for Significant Risk Sources of Hazardous Chemicals Verification, Registration Form for Significant Hazardous Sources of Hazardous Chemicals, Notice of Verification of Major Hazardous Chemical Sources, and Major Hazardous Chemicals Hazard Statistics Table. Each type of document specifies its content requirements in addition to the format. For example, when the “Characteristics of Major Hazardous Sources of Hazardous Chemicals†is filled out, when there are multiple (sets) of hazardous chemicals production facilities, facilities or sites in the hazardous chemicals unit, and the marginal distance between them is less than 500 meters, According to one unit to identify major hazards; when there are more than two major hazard sources in hazardous chemicals units, they should fill in the “Basic Characteristics of Major Hazardous Sources of Hazardous Chemicalsâ€. For storage tanks of hazardous chemicals, the quantity of hazardous chemicals is the quantity of hazardous chemicals corresponding to the maximum volume of the hazardous chemicals storage tank; for other containers, equipment or warehouses, the inventory of hazardous chemicals is containers, equipment or storage areas. The greater of the actual maximum stock of hazardous chemicals and the maximum stock of designs. The State Administration of Work Safety issued a new version of 10 safety production license documents for hazardous chemicals, including a new edition of the “Safety Production License Examination Document for Hazardous Chemical Production Enterprisesâ€, and required all hazardous chemical companies to use it from April 10, 2012. The 10 new license documents were prepared by the State Administration of Work Safety in accordance with the relevant provisions of the new “Measures for the Implementation of Safe Production Licenses for Dangerous Chemical Production Enterprisesâ€, including “Applications for Production Safety Permits for Dangerous Chemicals Production Enterprises†and “Dangerous Chemistry. "Safety Production License Review Form for Production Enterprises", "Dangerous Chemical Production Enterprise Safety Production License Extension Application", "Dangerous Chemical Production Enterprise Safety Production License Change Application", and "Dangerous Chemical Production Enterprise Safety Production License" "Notice of Completion of Application Materials for Certificates", "Notice of Acceptance of Application for Safety Production License of Hazardous Chemical Production Enterprises", "Notice of Site Inspection of Safety Production License for Hazardous Chemical Production Enterprises", "Safety Production License for Hazardous Chemical Production Enterprises The Notice of Application for Disapproval, the "Opinions on Solicitation of Safety Production License for Hazardous Chemical Production Enterprises" and the "Notice of Issuance of Safety Production License for Hazardous Chemical Production Enterprises". According to reports, compared with the old license documents, the review content in the "Safety Production License for Hazardous Chemical Production Enterprises" has increased from the original 24 items to 32 items. For example, whether a new company has been established in the area designated by the local people's government for the production and storage of hazardous chemicals, and whether the installations involved in hazardous chemical processes or those that focus on hazardous chemicals are designed by design agencies that meet the qualification requirements, etc. . The relevant person in charge of the Supervision and Administration Division of the State Administration of Work Safety stated that the new content is supplemented and perfected according to the new regulations on dangerous chemicals and the revised methods for the implementation of safe production licenses for dangerous chemicals manufacturing enterprises, and is intended to improve the nature of hazardous chemicals companies. The safety level and prevention of accidents are of great significance. Regenerated Nylon 6 is also called nylon 6 recycled material, which is generally produced by melting and granulating nylon yarn, nylon yarn or nylon cloth, because nylon 6 not only has good wear resistance, heat resistance, oil resistance and chemical resistance And processability, but also has dimensional stability and excellent mechanical properties, is widely used in automotive industry parts, gears, bearings, fan blades, pump blades, fishing gear, bicycle parts and some precision engineering accessories.
4.cn112853534a discloses a fiber manufacturing process, especially relates to a regenerated nylon 6 fiber manufacturing process, which includes the following steps: Step 1, pulverizing nylon 6 waste; Step 2, adding catalyst and ethanol and dichloroethylene A mixed solvent of alkane; Step 3, after the dissolution, filter the undissolved solids in the solution; Step 4, cool and crystallize the nylon 6 in the filtered solution at a certain temperature into a nylon 6 solid; Step 5, place the nylon 6 solid in Drying in an oven at 100-120° C. for 3-4 hours to make the water content less than 5%; Step 6, adding additives to obtain a mixture; Step 7, melt spinning to obtain regenerated nylon 6 fibers. The invention uses nylon 6 waste to produce regenerated nylon 6 fiber, which realizes the recycling of nylon 6 waste and fully avoids resource waste and environmental pollution.

3. However, nylon 6 will degrade during processing, resulting in the loss of molecular weight, affecting the melt strength and processability of the polymer, resulting in the inability of recycled or recycled materials to be used in occasions with high performance requirements, and even possible Being treated as waste is not in line with today's theme of green and low-carbon development. Therefore, how to recycle recycled nylon 6 materials to avoid resource waste and environmental pollution has become a hot research issue in recent years.
