1. Introduction to Pearl Cotton

1. Definition EPE is expandable polyethylene, also known as EPE. It is a high-foam polyethylene product produced by extruding low-density polyethylene as the main raw material.

2. Features:

Low density, good flexibility, high rebound rate; shock resistance is better than polystyrene plastic; has an independent bubble structure, low surface water absorption rate; good permeability resistance; acid, alkali, salt, oil and other organic solvents Excellent aging resistance; no flow at high temperature, no brittleness at low temperature.

It is composed of low-density polyethylene grease through physical foaming to produce countless independent bubbles. It is the most advanced protective inner packaging material in the world. EPE has high elasticity and white appearance. Because it is a completely independent bubble body, it is light, flexible, and flexible to absorb the impact force and disperse the effect of buffering. It overcomes the shortcomings of ordinary styrofoam, which is fragile, deformed and restored. Heat insulation, sound insulation, anti-friction, anti-aging, corrosion resistance and other characteristics. Strong anti-aging ability, good processability, pink EPE raw material with electrostatic agent added, also has significant anti-static function; fits with PO film, aluminum film flannel and other materials, can also increase its tear strength and prevent UV function.

3. Scope of adaptation:

EPE is widely used in electronic appliances, instrumentation, computers, audio, medical equipment, industrial control cabinets, lighting, crafts, glass, ceramics, household appliances, spraying, furniture, alcohol and gift packaging, hardware, toys, melons, leather shoes Packaging of various products such as inner packaging and daily necessities.

Adding anti-static agent shows its excellent performance. EPE pearl cotton is also widely used in elastic lining of handbags, industrial sound insulation, heat insulation materials, agricultural insulation materials, floating equipment for aquaculture, protective mats for sporting goods, rescue equipment for water operations, floor decoration for homes and hotels , Padding, etc.

Its pipes are widely used in industries such as air conditioners, strollers, children's toys, and furniture. The bonding products of EPE and various fabrics are good interior decoration materials for various vehicles and rooms.

4. Classification
Pearl cotton: ordinary pearl cotton, super flat pearl cotton , encrypted pearl cotton, encrypted hardened pearl cotton, anti-static pearl cotton , PO coated pearl cotton, aluminum foil pearl cotton, color-coated pearl cotton, pearl cotton, etc.

EPE profiled materials: tube-shaped, rod-shaped, L-shaped, U-shaped and various profiled materials, EPE components, EPE can also be processed into EPE bags of various sizes after being coated.

2. Pearl cotton process:

1. Cutting

According to the corresponding production instruction sheet and drawings, the composite sheet is cut to the size required by the customer's drawings.
Material / Equipment: Cutting machine, EPE sheet, tape measure, etc. Operation steps: According to the manufacturing order, loosen the "positioning baffle" of the vertical cutting machine, adjust the size of the material to be cut, and lock the "positioning baffle", Press the "cut open" button to start the machine and prepare for trial production. Use the straighter side as the datum plane to create another datum plane, and use a straight line on a platform as a reference to draw out the required size specifications.

2. Stamping

Shaped products are stamped according to customer drawings.
Material / Equipment: Punch, knife mold, pearl cotton block, tape measure, etc. Operation steps: Put the knife mold flat in the center of the feed slide, loosen the stroke handle, and set the "setting switch" to the set position (right-hand rotation) At this time, the punch automatically enters the setting procedure. After the knife die and the punch are fully in contact, the travel handle is locked and the "setting switch" is reset (left-handed). When it is found that the cutting cannot be performed during the work, adjust the cutting depth and adjust the time The longer the pressure, the greater the pressure until it just cuts.

3. Adhesive

According to the customer's drawings and samples, the materials that are cut and pressed in each process can be used to make the products that the customer needs.
Materials / Equipment: glue machine, rubber granule / rubber strip, pearl cotton material, tape measure, etc.
Turn on the power switch of the hot melt glue machine and the heater power switch, set the temperature of the "glue" to 170 ℃, the temperature of the "rubber wheel" to 150 ℃, after the rubber particles in the glue melted, then turn on the motor power switch, and Adjust the "motor speed" to the fastest, lightly press one end of the material to be bonded on the roller, slide it in the direction of the roller to the other end, and ensure that the glue is uniformly grained, and immediately glue the glue The EPE is attached to the corresponding parts of the adhered parts (cardboard).

4. Packaging

Material: packing machine, sealing tape, plastic bag, etc.
According to the production notice, check whether the product meets the quality requirements and confirm that it is a qualified product before packaging. The quantity and method of product packaging must be strictly in accordance with the requirements specified by the customer and the department.
