I-TPR TPU

I-TPR okanye irabha ye-thermoplastic iqhele ukudibanisa iipropathi ze-polystyrene (i-PS) kunye ne-butadiene (Syntanetic) irabha. Ezi zixhobo zaphuhliswa ukubonelela uninzi lwezibonelelo zepropathi yerabha yerabha ngelixa ivumela ukuqhubekeka (kunye nokuguqula) kwenkqubo echanekileyo nengalawulekiyo. I-TPR inikezela ukomelela kokukhathazeka, uzinzo lwekhemikhali, amandla empembelelo, kunye nokusetyenziswa ngokutsha, kunye nokuqhubekeka ngokuchanekileyo.

I-TPU okanye i-Thermoplastic Polyurthane ihlelwe ngokubanzi zePolymerthane Polymers ezabelana ngeepropathi ezinjengezi: ukucamngca, ukunciphisa ukomelela kweoyile. Izixhobo ze-thermoplastic, kunye nenqanaba ledigri ye-Elastomeric. Amandla abo aphezulu kunye nokomelela kuthathwe kwisakhiwo se-polymer equka ukutshintsha iziqwenga ezinzima nezithambileyo.

Eli nqaku liza kuthelekisa ngakumbi i-Tr. I-TPU, izicelo zabo, isebenzisa, iipropathi zomzimba, kunye nezinye izinto.

Yintoni i-TPR?
I-TPR (irabha ye-thermoplastic) iqulethe ukudityaniswa kwe-23% yeepesenti kunye ne-77% ye-vadiene. Ilungiselelwe yi-Emolsion Polymerization ye-polymers yendawo. Inkqubo yenza izinto ezingabonakaliyo ezinesigaba se-Elastomeric, iSigaba seThermoset, kunye ne-Matrix ye-therix yeZiseko zeTermoplastic. Isiphumo sifumana iipropathi ezivela kuzo zombini izinto kodwa ziyakwazi ukuqhubekiswa ngokuchaneka okuphezulu kwisixhobo esibunjiweyo. Ngolwazi oluthe kratya, jonga isikhokelo sethu malunga nerabha ye-thermoplastic.

Irubber eziqhelekileyo ziqokelelwe okanye ihlaziyiwe kwifom yepolymmerment, kwaye emva koko ubushushu busetyenzisiwe ukugqiba inkqubo yokunxibelelanisa. Kwimeko ye-TPR, icandelo lebhadiene lenziwa linxibe ngokupheleleyo kwaye liveliswe njengomgubo ocolekileyo. Icandelo le-PS emva koko ibanga i-faces-quid-lokuxhuzula ngokufaka irabha kwi-polymer ye-polymer eyomeleleyo. Iziphumo eziguqukayo zivela kwicandelo le-vadiene, apho i-Intra-Paricle i-Intrade i-Insebestic.

I-TPR ayihambelani nentsebenzo yeerubli ezenziwe ngamandla, ngoko ayiklungelanga ukuvelisa ityhure, iphantsi kakhulu kwimodyuli. Nangona kunjalo, i-ozone engcono-, imozulu yemozulu-, kunye ne-UVP enganyangekiyo ye-TPR kuthetha ukuba ifumana isicelo esibanzi kumacandelo emveliso emininzi.

Yintoni i-TPU?
I-TPU Polymers yenziwa ngamacandelo eebhloko ezinemimandla emide, [ethambileyo "yophawu olusezantsi, kwaye amafutshane, anzima" ophezulu kakhulu. Unxibelelwano olukhoyo phakathi kweentlobo ezimbini zecandelo zenza imixokelelwano edityanisiweyo efumana iipropathi ezivela kuzo zombini izinto. Ngokutshintsha amanqanaba eemolekyuli kunye nenqanaba lezinto ezibonakalayo, uluhlu olubanzi lweepropathi zinokufunyanwa kwizixhobo ezifanayo (phantse). Amaqondo obushushu eglasi yezi zinto zibini anokufana okanye abhale, kwaye akwazi ukutshintshwa ngamachiza ukuba aphezulu okanye asezantsi. Le micimbi yokulungisa ivumela ukuveliswa koluhlu lweepropathi ze-thermal yentsapho enomdla kwiziphumo.

Ukucofa okuphezulu kwezinto ezinzima zenza umtsalane onamandla, oxhasa imimandla ye-pseudo-rystalline, ebekwe kwi-matrix ye-elastic. Imimandla ye-pseudo-rystalline iziphatha njengezinto ezinqamlezileyo, ezichaza i-moducasti ephezulu yosapho, ngelixa ixesha elide, elithambileyo lenziwe ngokulinganayo kwesiphumo, ukuvumela ubunzima / ubunzima obuza kwenziwa.

Le phunga le-commack-copting incipha ukuya kwi-zero njengoko ubushushu beTrint yeGlasi yecandelo elinzima lidlulisiwe. Intsapho iziphatha njengeqela lezinto zezinto eziphathekayo ezinokuqhubekeka nezixhobo eziqhelekileyo eziqhelekileyo. I-TPU inokuphinda isetyenziselwe ukuphinda inyibilike kwaye iguquke, nangona i-Degradiswation kwi-chain ubude / ingqibelelo ibalulekile ekuthinjweni.

Kukho amacandelo entengiso aqhelekileyo kunye neendawo eziqhelekileyo zemveliso ezinokusebenzisa nayiphi na i-TRR okanye izixhobo ze-TPU. Ngokubanzi, izinto esisisiseko azithethi ukujongiswanga, njengoko isicelo ngasinye sisondela kwipropathi emxinwa enye okanye enye into. Umzekelo, icandelo le-AutoMotive lithanda ukusebenzisa i-TPRS ukuze iguqulwe ngokugqithileyo kunye nemozulu yemozulu, kunye ne-TPUs yokuqina, inxibe ukuxhathisa, kunye nezicelo ze-ergonomic

I-TPR vs. TPU: Ukuphinda usebenzise kwakhona kunye nokuzinza
Zombini ezi zinto zivela kwimithombo yepetrochemical, kunye nokuzinza kwazo kunye neziqinisekiso zokurisayikilisha kuyafana. I-TPU ihlaziyikeke kakhulu; Inkunkuma yayo inokuqhubekiswa ukubuyela umva kwezinto eziphezulu eziphezulu. Nangona kunjalo, idla ngokuba libanga lesibini ngenxa yokubekwa kwe-thermal. I-TPU ikwayakwa-biodegrade kwaye iyaphula ngokubanzi kwiimeko zokugcwalisa umhlaba / imikhwa engaphezulu kweminyaka engama-3-5. Alishiyanga intsalela enetyhefu xa iqhekeza. I-TPU ihamba kancinci kwaye inokwenzeka kwaye inokwenziwa kwii-sunors ze-bio.

I-TPR ikwanokuphinda isebenze kakhulu, kodwa njengee-polymers ezininzi, izinto ezisetyenzisiweyo zokuphinda zisebenze zibakala lesibini. Zizixhobo ezizinzileyo ezihlazisayo ngokuthe ngcembe kwindawo yendalo. I-ALGAL-Donomer Ene-Monomer Ene-Monomer Stoness ye-TPRS iyafumaneka.

I-TPR VS. TPU: Ixabiso
Ii-TPRs zihlala zinexabiso eliphantsi kakhulu, kuluhlu lwe- $ 1.60 ukuya kwi- $ 2.00 nge-kg. I-TPU ixabisa kakhulu, kwi- $ 2.00 ukuya kwi-4.00 kwi-kg nganye kg.

Ezinye izinto ezizezinye kwi-TRR kunye ne-TPU
Ukusetyenziswa kwenaliti yokubumba, iintlobo ezahlukeneyo ze-thermoplastic ze-Elastomeric ze-Elastomeric ziyafumaneka, kunye nemveliso ebanzi yepropathi kunye neendleko. Ngelixa ezi zingaguqukiyo kuluntu lonke, zininzi iziseko zepropathi ezikhokelela ekukhetheni kwinqanaba lenkcazo. Uluhlu olungezantsi luzinye izinto ezinokubakho:

I-thermoplastic gulcanistates (Tpe-v okanye i-TPV).
I-Thermoplastic Polyoolefins (TPE-O okanye i-TPO).
I-Thermoplastic Copolysters (Tpe-e, i-COPE, okanye i-teee).
