How To Use Acrylic Products Better2018-03-29 17:52:51
1. Note on the temperature:
PMMA long-term using temperature is 80 ℃, it will be curved in high temperature. So at least control the temperature below 50 ℃.
2. Damage, scratches attention
Acrylic resin surface hardness is about the same with aluminum, although it belongs to the harder type of plastic, but in use must pay attention to the scars. In order to protect the surface, in the acrylic resin paste the protective paper. In use, in order to prevent scars, adhesion dust, we recommend that you try to paste the protective paper as much as possible, and then peel off. Also, during work, protect the surface of the board while protecting your hands. Wear protective equipment, gloves, etc. When removing stains from the surface of the board, wash it with a soft cloth dampened with water or a mild detergent.
3. Note on the adhesion of dust precautions
If you use a dry cloth to wipe the acrylic resin surface, there will be a tendency to be charged by friction, easy to adhere to free air in the air and cause injuries, please note. We recommend that you wipe gently with a soft cloth dampened with antistatic agents or methanol containing an antistatic agent.
4. Notes on linear expansion
Acrylic resin, like many plastics, has a linear expansion coefficient that must be considered for its expansion and contraction due to temperature changes. It is desirable to be able to store and process (use) under constant conditions, with a temperature difference of, for example, about 1.4 mm per 1 m length at a temperature difference of 20 ° C.
5. Humidity considerations
Acrylic sheet will also have expansion due to humidity. The response speed is not as fast as the temperature changes, the use must be noted. If the plate is made to absorb water unevenly, its degree of extension varies depending on each part of the plate, and sometimes it may occur.
6. Solvent considerations
Acrylic sheet can cause cracking on the surface due to the corrosion of paint and solvent. Therefore, do not store it in a solvent vapors, such as paint storage rooms, spray booths, etc., in a clean venue.
7. Notes on combustion
Although acrylic are not flammable dangerous goods, but if the contact with the flame will be on fire, burning.
8. Precautions on the method of storage
Acrylic resin placement methods can be used horizontally and erected these two methods, each with its own advantages. Incorrect storage can lead to "warpage".
The following safekeeping method is recommended as a solution.
(a): When it is erected so that it is tilted by 10 °, keep the whole panel tight. In this case, the total thickness should be less than 30cm.Humidity considerations
