The principle of PU adhesive sealing for Led linear lights is as follows:
(1) the sealing construction should first seal the difficult parts, such as sunken, seam filling, laminating surface, box corner and other complex structural areas.
(2) the coating, injection and shaping of sealant should be completed within the application period of linear lamp sealant.
(3) pay attention to the clearance in the body of the line lamp, and when the clearance is 0.3-0.5mm, consider the use of sealant and solid gasket.
(4) coating on the sealing glue of linear light, as long as it does not affect the next process, it is generally not necessary to heat treatment, and it is better to cure naturally.
(5) the riveting and assembly of the sealing parts shall be carried out within the time limit prescribed by the sealant.
(6) the reactive sealant shall not be moved or beaten before curing, and the assembly, inspection and delivery shall be carried out after curing.
