The main component of PUR hot melt adhesive is isocyanate-terminated polyurethane prepolymer. The adhesiveness and toughness (elasticity) of PUR can be adjusted, and it has excellent bonding strength, temperature resistance, chemical corrosion resistance and aging resistance.
⒈PUR hot melt adhesive is solid, when heated to a certain extent, it melts into a liquid and spreads it on the substrate, and it will not melt again after curing.
2. Moisture curing, no drying process, fast and energy-saving; the adhesive layer has certain flexibility, hardness, and certain toughness.
3. Excellent initial strength, but also has the function of cross-linking and curing, and the final bonding strength is higher;
4. Single-component type, easy for industrial automation and mechanized operation, high production efficiency.
5. Because the product itself is solid, it is convenient for packaging, transportation and storage.
6. Does not contain any organic solvents, 100% solid content, non-polluting, non-toxic, green and environmentally friendly.
7. Excellent heat resistance, water resistance, chemical resistance, durability, etc.
8. And the advantages of simple production process, high added value, high viscosity and high speed, etc.
gaze.
9. Hot-melt adhesive has stable performance, high raw material utilization rate, fast production speed and high yield.
10. The equipment occupies a small area and has the advantages of small investment.
REHOW Textile Machinery is an outstanding textile machinery manufacturer with rich textile finishing and storage equipment automation and intelligent manufacturing technology. Professional PUR hot-melt adhesive compound machine, PUR hot-melt adhesive coating compound machine, hot-melt adhesive compound machine, hot-melt adhesive coating compound Microfiber composite machine) and other mechanical equipment R&D and manufacturing enterprises rely on scientific and technological progress to establish and improve product research and development, production and installation, testing, sales, and maintenance service systems. The products are favored by the market
PUR hot-melt adhesive compound machine equipment uses 100% solid hot-melt adhesive that does not contain pollution-producing ingredients. After being heated into a liquid state, it is evenly and regularly coated on the surface of the work to achieve the purpose of bonding. According to different processing objects, different coating forms such as dispensing, spraying, rolling, and fiber coating can be selected. Due to the simple operation of the equipment, reliable and fast bonding, high processing efficiency, and uniform coating with small glue consumption, no pollution to the environment, and in line with current environmental protection requirements, it is used in shoemaking, packaging, leather goods, paper boxes, accessories, building materials, etc. , Sports equipment, sanitary products, toys, electronics, electrical appliances, leather, furniture and other industries are increasingly selected as supporting production equipment.
Cleaning method Coating blade cleaning: After the equipment is heated, wipe it with dry gauze.
Roller shaft cleaning: use a clean dry gauze dipped in 75% alcohol to wipe the stainless steel roller shaft. If there is glue on the surface, use a dry gauze dipped in 1620 solvent/ethyl acetate solvent to wipe;
The glue on the surface of the rubber roller shaft must not be treated with organic solvents, so as not to damage the rubber roller shaft, it should be removed with strong viscous curing glue.
The outer surface of the equipment; cleaning method: wipe with a clean dry gauze dipped in 75% alcohol.
Batch change cleaning: PUR hot melt adhesive compound machine glue box and hose cleaning (applicable to changing the glue model and coating method): empty the original glue and add 2~3Kg of new glue, heat until completely melted, and then empty it completely. Then add a new type of glue, and drain at least 1Kg after it is completely melted to start formal production.
Coating head cleaning (applicable to changing glue models and coating methods): Wipe with dry gauze after the equipment is heated.
Coating and compounding roller shaft: Use a clean dry gauze to wipe the dust on the surface. If there is glue on the surface, do not use organic solvents to treat it, so as not to damage the rubber roller shaft. It should be removed with a strong curing adhesive.
Cleaning of the corona device: After confirming that the power is turned off, wipe it with a clean dry gauze dipped in 75% alcohol.
Cleaning of PUR hot melt adhesive laminating machine in non-fixed cycle: When the coating method and glue type grade are changed, the coating head of the PUR hot melt adhesive laminating machine must be cleaned. When cleaning, the coating head must be removed before the glue is solidified, and dry gauze should be used. Wipe the applicator tip clean with solvent. During the production process, the overflowing glue must be wiped off with a clean gauze when the equipment is shut down and turned on. Clean the filter screen of the glue box of the PUR hot melt adhesive compound machine for half a month. PUR hot melt adhesive compound machine coating head filter cleaning. If the production is stopped for more than one month, all coating equipment must be cleaned according to the above-mentioned content and requirements of daily, before and after batch change, half a month and non-fixed cycle cleaning before they can be put into use; After the original glue is emptied, about 30Kg of white mineral oil must be added to dissolve the residual glue. After emptying, about 30Kg of white mineral oil must be added to dissolve again, and it must be completely emptied before use.
