Acrylic sheet - identification
Identification of the quality of acrylic board quality, there are 14 kinds of methods, including the amount, smell, smell, fire, friction and so on.
1.See: mainly for the transparent board and whiteboard, to see whether the thickness of the yellow surface, to see the overall color difference, whether the color is uniform or not to determine the quality of acrylic or not one of the criteria;Quantity: Acrylic panel panel indicates whether the thickness is consistent with the actual thickness;
2.Smell: in the process of cutting whether the peculiar smell;
3.Fire: see the main flame color, after the fire to see the formation of bubbles, impurities and the length of the wire;
4.Friction: high quality acrylic material feel round and smooth, and without stains, fingerprints;
5.Cigarette burning method: with a complete cigarette, lit, were placed on the surface of two kinds of noodles, let it spontaneous, three minutes after the removal of smoke, unsaturated resin surface surface yellow imprinted deep, with wet paper After the imprint is difficult to eliminate, while the acrylic solid surface yellow impression is very shallow, with wet paper, the traces can immediately be eliminated or become very shallow, the number of wipes and the degree of difficulty to some extent to determine the performance of surface material Good or bad.
6.Paste the identification method: a good acrylic material after the paste is also posted together can be separated, and poor material after the soft paste together after it is difficult to separate;
7.Thickness identification method: the thickness of the acrylic weight bearing range of rigid standards, 8 to 12 cm is a common thickness, if the thickness of the material is good, but also cut corners;
8.Transparent identification method: good acrylic sheet material is very pure white, not yellow or blue, of course, light to be white, poor acrylic material is more brittle, the wind soon after the sun fade , Lost the original luster;
9.Glue edge identification method: generally good acrylic sheet factory has soft side;
10.Hot oil method: the oil heated to 200 degrees, the hot oil into the metal container, immediately placed on the surface of the plate, the water after the acrylic surface material surface will not have concave traces;
11.Coke soaking method: the acrylic material into the cola, more than half an hour out, wiped with paper, acrylic solid surface surface will not have any significant changes, or may not be a good acrylic plate;
12.Solvent method: into the cup with acetone, over 24 hours out, acrylic solid surface material at the same time can be observed soaked parts are more loose, and if other materials such as unsaturated resin will only burst phenomenon.
Identify the quality of acrylic board is the best way, the easiest way is to bend the board with the hand, the more tough the better the plate, hands with different plates in the distance about 50cm from the ground flat to throw the sound to the ground, sound crisp plate relative Impure, low sound of the plate is relatively good; or in the plate cutting, the smoke and thick taste of the plate relative to the small odor of poor taste.
