The PLC of the laminating machine is mainly selected as the monitoring center of the whole system to realize the whole process operation of compounding. PLC pneumatic components are exported from a specific pulse output port to control the pneumatic components LCD according to the predetermined position, alternately rotating the platform to the specified position in the circumferential direction.
Oil glue is a kind of odorless, has a strong feeling of pasting, strong adhesion, its advantages are good film-forming, good fastness, PU can be pasted warm air glue, is currently commonly used coating glue. The disadvantage is the use of oil solvents, so the lack of environmental protection, especially now oil prices, resulting in the rise in oil solvent prices, most of the coating glue because the cost is too high, so the use of poor oil solvents, resulting in environmental protection unqualified, in addition to the further improvement of environmental protection level, so the environmental protection requirements of the coating glue are getting higher and higher.
Oil glue is oil-filled glue, dry glue is not oil-filled! Theoretically, everything SBS can be used to make TPE, but it depends on the performance you want! The moisture of oil glue laminating machine is: water glue and oil glue. Water glue has a large water content and the price is relatively cheap. Oil glue is a semi-solid glue, of course, the price is also much more expensive. Oil glue costs three times as much as water glue. Oil-based coating glue is an oil-based solvent (toluene, DMF, which dissolves acrylic or polyurethane into a solvent.
Its advantages are good film-forming, good fastness, PU can be pasted warm air glue, is currently commonly used coating glue. The disadvantage is the use of oil solvents, so the lack of environmental protection, especially now oil prices, resulting in the rise in oil solvent prices, most of the coating glue because the cost is too high, so the use of poor oil solvents, resulting in environmental protection unqualified, in addition to the further improvement of environmental protection level, so the environmental protection requirements of the coating glue are getting higher and higher.
The adhesive (glue) is evenly transferred to the composite substrate through the roller, and then the adhesive (glue) is dried through the composite drying wheel to overlap the composite substrate. The work of capacities touch screen composite machine is slightly different: capacities touch screen composite machine is one of the main equipment in the LCD industry, mainly for the hard to hard combination between optical and rigid materials, such as optical double-sided adhesive (OCA) between double-layer glass substrates in the vacuum state, bonding, parts pressing, effectively overcome bubbles, rainbow patterns and other process defects, is an indispensable process in the touch panel combination process.
