Plastic mesh - what is polyethylene and how to identify polyethylene

Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene. Industrially, copolymers of ethylene and a small amount of an α-olefin are also included. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (minimum use temperature can reach -100~-70 °C), good chemical stability, and can resist most acid and alkali corrosion (not resistant to oxidation) Nature of acid). It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation.
Polyethylene materials are difficult to print (unless bulk modified or surface modified), so they are mostly colorless or light-colored products, and of course, due to their good environmental aging resistance, artificial turf on the sports field is mostly made of polyethylene. The simplest method of identification is to ignite a small sample with a gas flame (such as a lighter). The sample will continue to burn, have smoke, and have the taste of burning a candle. Use a nail to scratch it, scratched low density polyethylene (LDPE), otherwise high density polyethylene (HDPE).

Metallographic Cutting Machine

Easy to set up using an intuitive user interface that requires almost no training

The simple user interface and color display make operation very simple. No complicated menu. Use multi-function knob to set parameters, joystick to quickly position the workpiece, and automatically adjust the height of the cutting wheel. Yes, that's it.



The relocation of the workpiece is replaced by automatic X - axis movement

Thanks to optional X-axis movement, a series of cuts can be performed without wasting time repositioning the workpiece. The cutting table can be moved 40 mm, and the user can choose up to four sliders of different thickness.



With the help of a locator laser, the position can be reached on the first attempt

Positioning can be time-consuming, but Secotom uses a positioning laser to point out where to cut, and positioning becomes a breeze. The combination of laser and joystick enables easy positioning.



Cutting in a variety of sizes and shapes with the ultimate flexibility of the movable T-slot cutting table

Secotom's cutting table provides extreme precision and flexibility for a variety of sizes and shapes. Capable of cutting large and deep workpieces (up to 70 mm/2.8 "in diameter or 165 x 50 mm/6.5" x2 "in size). The cutting table is equipped with 8 mm T-groove, and users can choose from a variety of fixtures that are most suitable for their cutting operations and can achieve the highest accuracy of the toolaMetallographic EquipmentMetallographic Equipment
