The density is 1.04 to 1.09, the tanspaency is 88% to 92%, and the efactive index is 1.59 to 1.60. Unde the stess action, the biefince is poduced, that is, the so-called stess optical effect. The melting tematue of the poduct is 150~180 C, the themal decomposition tematue is 300, the themal defomation tematue is 70~100, and the long-tem use tematue is 60~80. At the lowe tematue of 5~6, the stess can be eliminated and the themal defomation tematue can be impoved. If a little alpha methylstyene is added to the poduction pocess, the heat-esistant gade of the eal polystyene can be impoved.It can be dissolved in aomatic cabons, ated cabons, aliphatic ketones and estes, but it can only swelling in acetone. Resistant to cetain mineal oil, oganic acid, alkali, salt, lowe alcohol and wate solution. The wate absoption ate is low, and its mechanical poties and dimensional stability can still be maintained in the wet envionment. The optical poties ae second only to acylic esin. The electical poties ae excellent, both the volume esistivity and the suface esistivity ae vey high, and ae not affected by the changes of tematue and humidity, and ae not affected by coona dischage. The adiation esistance is also good. Its main shotcomings ae bittle, bittle, low impact stength, poo heat esistance, and can not esist boiling wate. It can only be used unde low tematue and low load. The esistance to sunlight is poo and flammable. Black smoke and special odo when buning.System of laweal - pupose polystyene is made of styene a monome though fee adical polymeization o ionic polymeization. The methods of poduction include bulk polymeization, solution polymeization, suspension polymeization and emulsion polymeization. The main methods used in industial poduction ae suspension polymeization and bulk polymeization.1., the bulk polymeization method w used to feed styene monome into the pepolymeization kettle, then add a small amount of additives and initiatos, and then heat up and sti at 95~115 degees to pepolymeized. Afte the convesion ate eached 20% ~ 35%, it w then sent into a towe eacto with sties fo continuous polymeization. The polymeization tematue is aised to about 170 degees C, so to achieve complete convesion. A small amount of uneacted styene is eleed fom the top of the towe and can be eused. The polyme is dischaged fom the bottom of the towe continuously, and the finished poduct is obtained by the extusion ganulation. The pocess is follows.2. suspension polymeization with styene monome, wate medium, with gelatin o stach, polyvinyl alcohol, xyethyl cellulose potective glue o magnesium ca, magnesium silicate, calcium phosphate and othe insoluble inoganic salt dissing at, maleic anhydide styene copolyme two help dissing at, the initiato that w initiated polymeization at about 85 DEG C. It can also be polymeized at high tematue at high tematue above 100 C in high pessue polymeize without initiato. The polyme h been whed, sepaated and died to obtain a colouless and tanspaent bead like esin.Molding pocessPVC PVC potective wall panel is mainly used to eplace the aluminum potection wall panel. In addition to a pat of PVC esin, the est components of PVC floo tiles ae ecycled mateials, adhesives, filles and othe components. They ae mainly applied to the had gound of aipot teminal buildings and othe places.8. PVC daily consume goodsLage is a taditional poduct made of PVC, PVC is used to make all kinds of imitation leathe, used fo lage bags, spots poducts, such bketball, football and ugby. It can also be used to make belts fo unifoms and special potection equipment. Clothing with PVC fabic is adsoption fabic (without coating), such a poncho, baby pants, leathe jacket and boots. PVC is used in many spots and entetainment poducts, such toys, ecods and spoting goods, PVC toys and spoting goods gow a lot, because of its low poduction cost and ey foming.9.PVC coating poductsThe atificial leathe with a substate is applied to the cloth o pa with PVC pte, and then plticized above 100 degees C. It is also possible to extend the PVC and the auxiliaies to the film, and then combine with the substate. No atificial leathe substate is soft sheet diectly into a cetain thickness by the calende, then pess the patten can be. Atificial leathe can be used to make suitces, leathe bags, book coves, sofa and ca cushions, well floo leathes, used floo mateials fo buildings.10.PVC foam poductsWhen the soft PVC is mixed, a suitable amount of foaming at is added to make the sheet. Afte foaming, it is made into foam plt, which can be used foam slips, sandals, insoles, and shockpoof cushioning packaging mateials. The extude can also be used a new type of building mateial, which can be used a low foaming had PVC plate and special-shaped mateial, which can be used instead of wood.11.PVC tanspaent sheetPVC added shock modifie and oganotin stabilize, and became tanspaent sheets by mixing, plticig and calendeing. The use of themofoming can be made into thin wall tanspaent containes o vacuum pltic packaging. It is an excellent packaging mateial and decoative mateial.12. otheThe doos and windows ae made of had and special-shaped mateials. In e counties with wooden doos and windows aluminum doos and windows maket shae etc.; wood mateials, building mateials (steel, Noth Sea); hollow containe.The vitual cicuit is one of the sevices povided by the netwok packet switching (anothe datagam sevice), simply said, is though the intenal contol mechanism of the netwok, the establishment of vitual logical connection between the host and the use, ensue coect tansmission packet with the sequence of communication, befoe and afte establishment and emoval of vitual cicuit. The petual vitual cicuit is a vitual cicuit that is set up at the initialization of the netwok, and the vitual cicuit is kept. Both the X.25 netwok and the B-ISDN povide PVC sevices. PVC bags ae eally fobidden.Reseach on new mateialsEVA(4) toys. EVA esin also h moe applications in toys, such childen's wheels, cushions and so on.(5) hot melt adhesive. Hot melt adhesive with EVA esin the main component, because it does not contain solvents, no envionmental pollution and high safety, is vey suitable fo automated poduction lines, so it is widely used in books, funitue, wieless binding of automobiles and home appliances sembly, footwea, capet coating and metal anticoosion coating.(6) othes. EVA esin is also widely used in the fields of ink, bag, bottle cap and so on. It is estimated that the consumption of EVA esin in these ae is not less than 15 kt.Mateial deion of pat specification level of hot melt appeaance and coloThe use of compound, extusion, adhesive, sealant and waxNotes on heat stabilizes: antioxidants in BHTPocessing conditions fo pocessing conditionsTechnical data of aw mateialsfomance poject test condition [state] test method test data unitPhysical fomance density TM D-792/ISO 11830.957 g/cm3Melt flow ate 190/2.16kg TM D-1238/ISO 113343 g/10minVA content 32%Themal fomance melting point (DSC) TM D-3418/ISO 314663 (145) C (F)VEKA softening point TM D-1525/ISO 30636 (97) C (97) C (F)Physical poty table
