On a certain day in the summer of 2001, when a color printing plant in the northeast was carrying out compounded plastic production, the plastic film on the laminating machine coating mechanism suddenly caught fire. When the flame of the flame is blown to the drying tunnel by the film laminating machine, it quickly ignites the glue in the glue box under the glue disk, and the thinner, compound glue, BOPP film, ink and paper stored in the workshop, etc. A sea of ​​fire. Although the rescue was timely and caused no major injury to personnel, the laminating machine and the multi-color printing press had become a pile of scrap iron and had a direct loss of nearly 8 million yuan.
In the past 10 years or so, all manufacturers across the country using the gluing process to produce composites have used paper/plastic composites or plastic/plastic composites. In different seasons, BOPP films have been used to apply adhesives. An instant fire accident.
“Hidden danger is more than open flame, prevention is better than disaster relief, and responsibility is more important than Mount Tai.†When it comes to laminating, it has become an important means for all kinds of printed post-press precision in China. It uses new scientific and technological means and macromolecular materials to change the nature of the original. This kind of material is processed by various laminating machines to form a new composite material with excellent performance, beautiful appearance and practicality, convenient processing, transportation and preservation. It has been widely used in printing, packaging, surveying and mapping, advertising, food, medicine, seeds and other industries. The application and continuous extension to other fields of production and life, that is, the fire of the glue-applied composite technology has become another safety hazard following the “bubbling†and film-breaking quality accidents, which are waiting for us to analyze and prevent. eliminate.
To eliminate the fire disaster in the production of paper/plastic and plastic/plastic composites, it is necessary to reform the compounding process that is inseparable from the production of a solvent for flammable products. Under the premise of not changing or replacing the original film-covering machine, it is improved to use a hot-melt adhesive without any solvent to coat the dry composite new process.
Over the past few years, a large number of printing, packaging, and surveying and mapping industries throughout the country have proven that the new process of hot-melt adhesive pre-coating dry-film composite technology uses no solvents, is non-toxic and tasteless, is simple and quick, saves time and labor, is safe and reliable, and saves a lot of The electric energy has completely solved the problems of “bubbling†and film release quality that have traditionally occurred in the rubber compounding process, and at the same time eliminated potential fire hazards that have jeopardized workers’ personal safety and state property for many years and were quickly promoted and applied. Manufacturers who have not adopted the hot-melt adhesive pre-coated dry composite new technology should do the following preventive measures:
1. Smoking and lighters such as lighters, matches, etc. shall be strictly prohibited within 5m of the production workshop, storage of adhesives and thinners, and its surroundings. No open fire shall be used.
2. It is forbidden to wear chemical fiber clothing and nail shoes that do not meet the anti-static requirements.
3. All types of film-covering machines, plastic-printing machines and slitting machines should have good grounding devices.
4. Adhesives and thinners should be handled lightly and gently, and it is prohibited to throw or drag, and the anti-site iron drums should collide with each other. Do not use a metal hammer such as a hammer shovel to knock open the barrel to avoid sparks.
5. Contact points such as motors, electrical appliances, circuits, switches, etc. should be clean and secure, to prevent sparking due to poor contact or short circuit during switching.
6. The runners of the various parts of the machinery must be kept in good lubrication, the friction parts of the parts should be made of non-ferrous metals or other non-sparking materials.
7. An effective protective net cover should be added at the suction port of the electric pump that transports the compound glue mixture.
8. The storage of binder mixture, the container used for blending, and the pipeline for transporting and returning, use metal products with smooth inner walls.
9. Install a self-sensing static eliminator.
10. Sprinkle water and use a humidifier.
11. There is a good exhaust ventilation device to reduce the concentration of volatile gases in flammable liquids
