Goobta codsiga iyo rajada horumarinta ee alaabta polyurethane ee laastikada ah

Elastomers Polyurethane waxay ka tirsan yihiin polymers-ka xannibaya, taas oo ah, macromolecules polyurethane waxay ka kooban yihiin "qaybo jilicsan" iyo "qaybo adag" waxayna sameeyaan qaab-dhismeedka kala-soocida wajiga yar.Qaybaha adag (oo ka soo jeeda isocyanates iyo silsiladaha silsiladaha) ayaa ku kala firirsan gobolka wajiga qaybta jilicsan (oo ka soo jeeda oligomer polyols) waxayna ciyaaraan doorka dhibcaha iskudhafka jirka.Sidaa darteed, marka la barbardhigo caagadaha kale ee synthetic (elastomers), polyurethane elastomers waxay leeyihiin awood ka fiican waxayna xidhaan caabbinta, Kordhinta sare ayaa weli la ilaalin karaa marka ay adag tahay.

Qalabka poliurethane ee laastikada ah, oo loo yaqaan "kiis" wadamada shisheeye, inta badan waxaa ka mid ah alaabada elastomer polyurethane dhaqameed, poliurethane caag ah oo caag ah iyo qalabyada kale ee laamiga ah, daboolka biyuhu polyurethane, dhejisyada, dhejisyada, dhejiska dheriga, iwm, oo xisaabinaya qiyaastii 40% tirada guud ee alaabta poliurethane.Inta badan alaabada la daaweeyay ee walxaha kiis (alaabada biyaha ku salaysan iyo kuwa dareeraha ku salaysan ayaa ka saara biyaha iyo dareerayaasha) waa walxo poliurethane ah oo aan xumbo lahayn.Xabagta maqaarka synthetic ee PU, dahaarka qaarkood iyo koollada ayaa ah alaabada dareeraha ku salaysan ama aqueous, kuwaas oo sidoo kale loo arki karo inay yihiin elastomer polyurethane ah dareen ballaadhan.Dareen cidhiidhi ah, elastomer polyurethane waxa loola jeedaa kabka polyurethane elastomer (CPU), elastomer polyurethane thermoplastic (TPU) iyo elastomer polyurethane isku dhafan (MPU), oo xisaabinaya 10% ama wax yar ka yar wadarta polyurethane.CPU iyo TPU waa elastomer-yada ugu muhiimsan ee polyurethane, kala duwanaanshooduna waxay ku jiraan arrimo ay ka mid yihiin habka wax soo saarka iyo silsiladaha fidiyaha.Noocan ah elastomer-ka dhaqameed ee polyurethane, oo sidoo kale loo yaqaan "caagga polyurethane", ayaa iska leh nooc ka mid ah caag synthetic gaar ah.Waxqabadka sare ee elastomer polyurethane waa shayga leh iska caabbinta xidhashada ugu fiican ee dhammaan walxaha polymer synthetic.Waxaa loo yaqaan "boqorka caabbinta xirashada".Waxaa si ballaaran loo isticmaalaa meelo badan, iyo codsiyada cusub ayaa weli sii ballaarinaya.

Elastomers Polyurethane waxaa loo isticmaali karaa in lagu beddelo biraha, balaastikada iyo caagga caadiga ah ee meelaha qaarkood.

Marka la barbardhigo qalabka birta ah, elastomer polyurethane wuxuu leeyahay faa'iidooyinka miisaanka fudud, qaylada hoose, caabbinta luminta, kharashka wax-soo-saarka hooseeya iyo caabbinta daxalka aashitada.Marka la barbardhigo balaastikada, waxay leedahay faa'iidooyinka adkaanta sare iyo caabbinta xirashada sare.Marka la barbardhigo caagga caadiga ah, elastomer polyurethane wuxuu leeyahay faa'iidooyinka xirashada caabbinta, jarista caabbinta, caabbinta jeexjeexa, awoodda wax-ku-qaadista sare, caabbinta ozone, wax-soo-saarka fudud, dheriga iyo shubista, iyo kala duwanaanta adagaanta ballaaran.

Elastomer Polyurethane waa nooc muhiim ah oo poliurethane ah.Waqtigan xaadirka ah, isticmaalkeedu wuxuu xisaabiyaa ku dhawaad ​​10% wadarta guud ee isticmaalka polyurethane.elastomer Polyurethane waxaa loo isticmaalaa in lagu soo saaro dhammaan noocyada taayirrada caagga ah, suumanka gudbinta, tuubooyinka caagga ah ee biyaha u adkeysanaya iyo cadaadiska u adkeysanaya, xargaha xiritaanka iyo faraantiyada, galka fiilooyinka iyo filimaan kala duwan.Alaabooyinka waxaa si weyn loogu isticmaalaa birta iyo birta, waraaqaha, macdanta, mishiinada, daabacaadda iyo warshadaha kale.elastomer Polyurethane waxaa wax ka beddeli kara polymers kale, fiilooyinka, buuxinta budada, iwm. si loo yareeyo kharashka loona hagaajiyo waxqabadka.
