Don't look down upon the aging of composite membrane link, do not pay attention to a major accident

Slaking merely composite membrane was placed into the curing room, in the time of finishing and remove that simple? Of course, the answer is 'no'! Slaking if control is not good, can make in front of the composite drain, resulting in the composite membrane of peel strength, open sex difference, have peculiar smell, as well as the quality problems and is a large amount of scrap, cause large quantities of quality accident. Management of curing method, then, in the actual work, how do we do the curing management of composite film? 1, must complete the design of the curing room, especially the curing chamber heating system design at present, the domestic common curing chamber in the heating system with heat and heating two kinds. Outside heating refer to heat the air in the curing room at a certain temperature, then the hot air into the curing room, with a fan in heating is to point to in cure indoor heating pipe installation, make indoor air temperature. , no matter what kind of heating mode to achieve the curing room temperature stability, uniform, for the purpose of using in heating mode, had better install the heating pipe at the bottom of the curing chamber, and additional fan. Conditional manufacturer, it is better to install at least two curing chamber, a temperature setting in 40 ℃ ~ 45 ℃, a temperature setting at 50 ℃ ~ 55 ℃, respectively, for different aged composite membrane for use. 2, good film curing time and temperature management at present, almost all the brands on the market for its curing time and the types of adhesives are specified on the instruction for use, but in practice, we often can see some soft packaging manufacturer or because the time of delivery is too urgent and shorten curing time, either because the process can't keep up with the progress after prolonged curing, and shorten curing time may lead to adhesive curing incomplete and affect the peel strength or residual odor, and the curing time is too long can lead to bad film open sex. So, it is necessary to set up the curing time registration form ', will be composite good film coil number, the register into the room and take out the curing time, explanation of the operation time, strictly in accordance with adhesives such as did the delivery date is too urgent, quick dry type ester can be used or alcohol soluble polyurethane adhesives composite soluble adhesives. Said earlier is best can install two different set temperature curing chamber, that is because different material of the structure of the composite membrane of curing temperature requirement is different. Composite process of management of every detail that nots allow to ignore, only will every work into practice, have achieved & other Can be controlled & throughout; To get the best composite effect.
