The main uses of PPSChemical stability, dimensional stability, flame etadancy and electical insulation, etc. In the chemical industy can be used as PPS synthesis, tanspot, stoage tank, pipeline, valve, eaction chemical pumps, PPS can be made in the mechanical cente of impelle, blade, eccentic wheel, gea, beaing, clutch and wea pats; the main pupose of PPS is still in the field of electonics, such as the poduction of high-fequency tansfome skeleton, coil skeleton plug, socket, wiing, fame, dum dum contacto tablets and a vaiety of pecision pats etc..Mateial popeties1, electical insulation (especially high fequency insulation) is excellent, white had and bittle, falling on the floo with metal noise, light tansmission ate is second only to plexiglass, with * * * wate esistance, chemical stability is good. It has excellent flame etadancy fo non flammable plastics.2, the stength is geneal, the igidity is vey good, but the quality is cisp, easy to poduce the stess embittlement, does not endue benzene, the gasoline and so on oganic solvent. The long-tem use tempeatue can each 260 degees, maintains the stability in the 400 degee ai o the nitogen. By adding glass fibe o othe einfoced mateials afte modification, can geatly impove the impact stength, heat esistance and othe mechanical popeties ae also impoved, the density inceased to 1.6-1.9, mold shinkage to 0.15-0.25% suitable fo the poduction of heat-esistant pats. Insulation and chemical equipment. Optical instument pats etc..Blending modification with PA1010The blends of PA11 and PA1010 wee pepaed unde diffeent mass atio, and the melting tempeatue, mechanical popeties, heological popeties and micostuctue of the blends wee studied. The esults show that the quality of the blends is 90: 10 when the amide exchange eaction is a single melting tempeatue; impact pefomance in a mass atio of 90: 10 and 70: 30 when the maximum value when the mass atio of 90: 10, PA11/PA1010, the viscosity of the blend inceased suddenly (incease than pue PA11 30%) quality; the atio of 70 to 30 when the viscosity of the blend is about 20% with pue PA11, the heological popeties of blends and stability. Consideing the pocessing and impact popeties, the mechanical popeties of the blends with the mass atio of PA11 and PA1010 to 70: 30 ae bette than that of pue PA11, and the cost is obviously lowe than that of pue PA11.Blending with PA6, because of the stong polaity of PA6, the wate absoption ate is lage, and the stength and modulus decease, and the dimensional stability is affected. PA6 has low toughness at low tempeatue. The blend of PA11 and PA6 makes the blends have good mechanical popeties and educe the pice of PA11.Futhemoe, such as the ecent two yeas, India intecontinental ecycling company has poduced qualified ecycling PET, accoding to epots, the India state-owned intecontinental ecycling company Indian-ownedIntecontinentalRecycling is located in the nothen England egion of the Skelmesdale device began tial opeation in Novembe 2007, accoding to the plan, the device can ecovey and tansfomation of 30 thousand tons pe yea of waste plastic bottles. In addition, the device has some equipment fo soting, washing and dying, and the poducts poduced will be hot pot flakes fo non food poducts. Consumes can use this mateial to package non food poducts o to sepaate two layes of edible mateial as intemediate. In the UK, the maket pice of egeneated PET bottles fo non food poducts is about 600 pounds pe ton.In addition, Japanese entepises successfully developed ecycled and egeneated PET modifie. It ecalled that the containe ecycling method was implemented in Apil 2000 in Japan. In 2006, the ecovey of PET bottles eached 390 thousand tons, eaching only 60% of the ecovey ate. The technical poblem fo ecycling and euse fo PET. The two bands of ecycled PET modifie, "AR-P-1000" and "AR-P-1100", wee successfully developed fom Japan to the maket. The main chaacteistics of AR-P ecycling egeneative modifie ae: (1) no dying teatment is needed. It is vey stable at oom tempeatue. It is suitable fo all plastic foming and pocessing equipment. (4) can be coloued abitaily. Blends can be added diectly. To enhance the impact stength of PET ecycled mateial molding. As AR-P is dispesed in a fine state in the ecovey of PET molding mateials, the intefacial tension is small unde the shea foce of the molding pocess. The viscosity atio of AR-P to ecycled PET molding mateial is 1, and the dispesion is good, which impoves the impact stength of ecycled PET molding mateials. Fo example, when adding 5% "AR-P", the notched impact stength is inceased fom 2KJ/mz to 5.5KJ/m2. In a 10 DEG C low-tempeatue impact stength inceased fom 1.BkJ/mz to SkJlm2o and impove the ecycling of PET mateial viscosity, impove the flow pefomance of PET melt molding mateial, suitable fo pocessing complex shape, pofile extusion molding poducts.
