How to judge whether the polishing glue is qualified? Two pieces of bonded materials can be torn apart along the bonding interface. If the bonded materials are found to be damaged after tearing, the bonding strength is sufficient; if only the bonding interfaces are separated, it indicates that the strength of the water-based white latex is insufficient. Sometimes water-based white latex with poor performance will be degummed and brittle after being stored in a high temperature or low temperature environment for a period of time. Therefore, it is necessary to do high temperature thermal change and low temperature embrittlement experiments to determine whether its quality is reliable.
The polishing glue has strong adhesion to PVC film, PVC board, wood, fiberboard, etc. It is mainly used for bonding the color box after polishing and polishing. The skylight is pasted with PVC paper and the paper (board) is used to make the color box seal. Edges and speakers are made of PVC leather, and handbag edges are sealed. It can also be used for bonding PVC plastic and paper, and bonding wood, plywood, fiberboard and other materials. Treat the surface of the article so that the surface of the article is free of oil, dust and other impurities. The bonding surface should be in full contact. Glue should be uniform and appropriate. After sizing, it should be left in the air. For products with too much stiffness, they should be pressurized after bonding.
The polishing glue does not contain organic solvents, is non-toxic, does not pollute the environment, has a high solid content, and has a fast bonding speed. It is widely used in stiff wood or fiberboard lining boards such as sugar, wine, tea, moon cakes and laminated paper for exterior decoration. The pasting and wrapping are bonded together, and the bonded packaging box has no peculiar smell, which meets the requirements of environmental protection and food hygiene.
