Vacuum glue or membrane glue
What is pvc adhesive
Membrane adhesive is a kind of polymer that is used to coat MDF-PVC surfaces and is the result of a complex formulation based on water. It is presented in two models of Vacuum 2 and adhesive, one component, and the same As it is known, the single-component membrane adhesive does not need to add another material and itself has its own thermal resistance, but PVC and two-component PVC adhesive requires the addition of another material called Isocyanol to membrane adhesive. To the thermal resistance of the adhesive and the adhesive, this value is 25 cc for each membrane adhesive. The important point is that the adhesive of the vacuum produced to This method should be used within 10 hours after combining with Isosinanol. Otherwise, the adhesive is unlikely to be used
Notes on Vacuum Glue or Membrane Glue
Vacuum glue is also known as membrane adhesive or viscous PVC adhesive. When purchasing adhesive Vacuum Pvc, or membrane adhesive, you should consider the following points
When purchasing adhesive adhesive, care should be taken to ensure that the viscose adhesive matches your color in terms of color. Certainly, the more natural colors can be better
The useful time for membrane adhesive is also one of the other factors at the time of purchase. For example, at a temperature of 50 °, how useful is the membrane adhesive timing to be considered in its catalog
Basically, the adhesive is a good vacuum that does not need to be blended or less, and less bulk. Of course, in devices that use these adhesives, they are mixed in the same ratio of time in the tank
The good vacuum glue must have a high resistance to water
Factors such as assembly time and clamping should also be considered, which should be lower for higher temperatures at this time
A good membrane glue should work with the lowest possible pressure, and this is a very important point, and maybe the performance of your press machine will affect over time, since with minimal pressure you can do vacuum work
Application of pvc adhesive in wood industry
One of the uses of pvc adhesive is the production of a waterproof door, or any type of coating that needs to be coated with artificial veneers. More PVC and PVC for PVC bonding on MDF. Inside the press machine
Recipe Using Membrane Glue
Membrane adhesive is a spray adhesive
The spray booth or spray gun must be made of stainless steel or plastic
The nozzle hole diameter should be 1 / 5-1 / 1 mm
The edges and surfaces of the tool should be sprayed twice, which should be sprayed first after complete drying for the second time. As long as the white film is created on the edge of the workpiece, the film is dried after a clear, It’s a little sticky on the remaining surfaces and the readiness to perform press operations
Place the piece in the tray and load the cover
Important: Note that the entire duration of the press operation from the moment it starts to heat until the end of the vacuum operation is not more than 300 seconds (after this time, the reactivity of the membrane adhesive has been completed and no longer has the ability to absorb the coating)
cleaning
Use cold water to clean the membrane glue tank
