How to ensure that the sheet and the film will not blister or paste poorly after the PUR flat laminate machine is laminated.
First of all, the constant temperature and humidity environment is very important for the PUR flat laminate machine to produce good finished products. PUR hot melt adhesive is a very sensitive material whose properties are greatly affected by temperature and humidity. In a constant temperature and humidity environment, PUR hot melt adhesive can maintain a stable viscosity and flow, thus ensuring the quality and accuracy of the fit.
If the ambient temperature and humidity are unstable, the viscosity of PUR hot melt adhesive may change, and the fluidity will also be affected. This can lead to quality problems such as poor fit, glue overflow, and bubbles, which can affect the appearance and performance of the product.
Therefore, in order to ensure that the PUR flat laminate machine produces high-quality finished products, a constant temperature and humidity environment is essential. By maintaining a stable temperature and humidity environment, the influence of external environmental factors on the performance of PUR hot melt adhesive can be minimized, so as to ensure the stability of production and product quality.
Secondly, the curing time of PUR glue is longer, and it takes a certain amount of time to fully cure.
Before the glue is fully cured, the surface of the sheet may be affected by external factors, such as dust, dirt, etc., which may cause the surface of the sheet to be uneven or the bonding strength to decline. Therefore, placing the plate in the health room for health, waiting for the glue to be completely cured before use, is an important step to ensure the bonding effect and the surface quality of the plate.
It should be noted that the curing time of PUR glue is affected by temperature. In the case of lower temperatures, the curing time of the glue may be extended. Therefore, when using PUR glue, it is necessary to reasonably arrange the health time according to the specific temperature situation to ensure the complete curing of the glue.
