Manual or semi-mechanical grinding to the main belt or sandpaper, Acrylic Display the use of abrasive belt or sandpaper grinding, due to relatively soft, Acrylic Display good paste type, grinding contact area is larger, less heat, heat is good, not only high production efficiency, Acrylic Display Grinding quality is good, Acrylic Display and suitable for grinding complex forming surface. Coarse grinding when the use of large grain size abrasive, fine grinding when the use of small particle size of the abrasive. Note that cooling must be carried out during grinding, Acrylic Display usually with water as coolant.
When the acrylic display frame is manually polished, Acrylic Display it should be affixed to the polished surface with a pressure of about 5 to 10 N with a fine wool or dipped cotton ball with a polished wax, and evenly linearly along the length of the process at a speed of 100 to 120 r / min , Usually 1 ~ 2mm per second forward. Be careful not to focus too much on a part of the polishing, so as to avoid the formation of local friction overheating and processing depression. Also note that the polishing surface of the polished wax should not be too dry, should pay attention to feeding lubrication.
Polishing wax for acrylic polishing, polishing process to become one of the key process materials. Polished wax has the advantages of high polishing speed, Acrylic Display high finish and long service life, and can change the polishing quality and operating environment. For example, Acrylic Display polishing with a rare earth polishing wax, a minute to complete the workload, such as the use of iron oxide polishing wax will take 30 to 60 minutes. Rare earth polishing wax because of its unique chemical and mechanical role of the principle of polishing efficiency, as the acrylic display frame polishing process materials of choice.
The biggest difference between polishing and grinding is that the polishing does not change the dimensional accuracy of the workpiece, but only removes the fine lines and stains from the acrylic display frame, improves the surface finish, reduces the haze until it gets a specular gloss, Add polished wax between the machined surfaces.
Acrylic products have excellent performance, in the mall we can see a variety of beautiful cosmetics counters, mobile showcase, and put all kinds of snack goods shelves, food boxes, etc., Acrylic Display you will find are acrylic figure In the major shopping malls or stores, we can see the acrylic products play a great role, especially in the cosmetics counter, the acrylic props is indispensable. Acrylic Display So what is it special and advantageous?
1, a high degree of transparency: plexiglass is the most excellent polymer transparent material, light transmission rate of 92% higher than the glass transmittance.
2, high mechanical strength: plexiglass relative molecular mass of about 200 million, Acrylic Display is a long chain of polymer compounds, Acrylic Display and the formation of molecular chain is very soft, so the strength of plexiglass is relatively high, anti-tensile and impact resistance 7-18 times higher than ordinary glass.
3, light weight: plexiglass density of 1.18kg / dm3, Acrylic Display the same size of the material, its weight is only half of ordinary glass, metal aluminum (light metal) 43%.
4, easy processing: plexiglass can not only use the lathe cutting, drilling drilling, and can use acetone, chloroform and other bonding into a variety of shapes of equipment, Acrylic Display but also with blow molding, injection, extrusion and other plastic molding method Processed into large aircraft cockpit cover, small to dentures and dental care and other products.
