Pc advantages:
High intensity and elasticity factors, high impact intensity, wide use of temperature range; 2, high transparency and free chromosomality; 3, h. D. T. High; 4, high resistance fatigue; 5, high tolerance and electrical properties; 7, low odorlessness and no harm to humans, consistent with health safety; 8, low formation contraction and good size stability. Extensively applied: 1. Optical lighting: transparency material used in the manufacture of large lamps, glass protection, and also on aircraft. 2. Manufacture of insulation plugs, coil frames, tubes, insulation tubes, telephone casings and spare parts, ores, batteries, etc. Communications equipment such as cd-roms, telephones, computers, video cameras, telephone exchanges, signal relays, etc. Polycarbonate is also widely used as a capacitor, insulation bag, audio tape, colour tape etc. 3. Mechanical equipment: used in the manufacture of gears, gears, snails, snails, bearings, cams, bolts, levers, curved axes, thorns, etc., may also be used as parts of mechanical equipment casings, covers and frames,
Sticky pc plastic
Depending on the needs, the following adhesives can be selected:
1. G-933: single-assembled solidified soft, flexible anti-shock adhesives, resistant to high and low temperatures, solidified for several seconds to several hours at different viscos。
2. Kd-833 transient adhesives capable of fast binding pc plastics for seconds or seconds and impregnated with hot water above 60 degrees。
3. Qn-505, double-assembled glue, suitable for large area adhesion or compounding of pc plastics. But the performance is poor。
4. Qn-906: double-assembly concentrate。
5. G-988: single-assembly chamber temperature sulfide glues, water resistant, anti-shock adhesives, high and low temperatures, 1-2 mm thick, 10 minutes early solidification, 5-6 hours basic solidification, with some intensity
Characteristics: flammability compliance with industry ul94 v0/1. 5 mm; certification through ul in the united states; impact of a falling ball with a free fall of 1. 3 m/500g; welding with a free drop test; thermal deformation temperature (1. 82 mpa/3. 20mm) is 127°c。
Applications: mainly for electrical appliances such as chargers, headlamps, switch panels, oa equipment, etc。
High flow-retarded pc materials
Characteristics: good mobility and ease of formation; low rate of formation contraction; better resilience, sprayable, sculptor; good flame retardation, up to ul v0/1. 5。
Application: triple-protective mobile phones, flat-shells, one computer backcap, etc。
