Acrylic Risers stability
Acrylic is an important early development of thermoplastic, with good transparency, chemical stability and weatherability, easy to dye, easy processing, beautiful appearance, in the construction industry has a wide range of applications.
The thermoforming of acrylic products is the process of making plexiglass sheets or sheets into various sizes of shaped articles, clamping the blanks of the desired size onto the mold frame, heating them to soften, and pressing Mold surface, get the same shape with the surface, after cooling the finishing edge of the finished product.
Pressing can be carried out by vacuum drafting or by direct pressing with a punch with a profile. When using a fast vacuum low draft forming product, it is advisable to use a deep drawing product that is close to the lower limit temperature and has a complicated shape. Close to the upper limit temperature, under normal circumstances the use of normal temperature. For the modern enterprise product upgrades, technological innovation glory luster. Acrylic products by the customer's welcome, for acrylic products printing, more and more customer requirements tend to more colors And high-precision images.
The first element is whether the machine's input / positioning system is properly adjusted to ensure that each position of the acrylic product is accurate from the input to the printing positioning device.
The second element is the tension of each screen is consistent.
The third element is whether the acrylic products in the process of printing several times by the machine and the workshop of the various factors.
To deal with the above three elements involved in the problem, the color can be accurate to meet customer requirements of the acrylic products printing, the need to achieve positioning, color sequence, overprint three steps, registration is particularly important. Acrylic products in the relatively high temperature Can you use it, will it be deformed or melted?
Acrylic sheet Chemical name Poly methyl methacrylate, it has a certain high temperature resistance, temperature can reach 104 ℃, but the maximum continuous use of temperature with the working conditions vary between 65 ℃ -95 ℃ change, the temperature reaches about 96 ℃ (1.18MPa) will occur slightly deformed, softening point of about 113 ℃, of course, we use acrylic products can not be exposed to high temperature, the general will not be a problem, the melting point of acrylic at 230-260 degrees.If the acrylic products with At minus 20-30 ℃ cold areas, chemical molecules will be severe contraction, resulting in brittle, it is easy to break.
Resulting in the deformation of acrylic products in addition to the temperature, but also with the thickness of the acrylic have a great relationship, the thinner the more easily deformed, the more thick the more difficult to deformation, so the use of acrylic products to keep the temperature within a reasonable range, if the special environment , Can do other necessary processing.
