TPR TPU

I-TPR noma i-Thermoplastic Rubber imvamisa i-copolymer ehlanganisa izakhiwo ze-polystyrene (ps) ne-buthadiene (zokwenziwa) irabha. Lokhu kwakhiwa kwasungulwa ukuhlinzeka ngokuningi kwenzuzo yempahla yenjoloba zokwenziwa ngenkathi kuvumela ukucubungula (nokuphindiselwa) kwinqubo eqondile enokulawulwa umjovo. I-TPR ihambisa ukubekezelela ukukhathala okukhohlisayo, ukuqina kwamakhemikhali, amandla omthelela, nokuvuselelwa okulinganiselayo, ngokusebenza okulungile.

I-TPU noma i-thermoplastic polyurethane iyihlukaniso elibanzi lama-polyurethane ama-polymers abelana ngezakhiwo ezinjengokuthi: ukuqina, ukuvezwa, ukugqoka ukuqina, kanye nokumelana okuphezulu kakhulu kumafutha. Izinto zokwakha zingu-thermoplastic, ezinamazinga ahlukahlukene wokuziphatha kwe-elastomeric. Amandla abo aphezulu nokuqina kwawo kutholakala esakhiweni se-polymer chain equkethe ezinye izingxenye ezinzima nezithambile.

Lo mbhalo uzoqhubeka uqhathanise i-TPR vs TPU, izinhlelo zabo, ukusetshenziswa, izakhiwo ezibonakalayo, nezinye izinto zokwakha.

Yini i-TPR?
I-TPR (Thermoplastic Rubber) imvamisa iqukethe ukuhlanganiswa kwama-23% ps kanye nama-77% buthadiene. Ilungiselelwe yi-emulsion polymerization yama-polyments akhona. Le nqubo yenza into ehlukanisekayo equkethe isigaba se-elastomeric, i-thermoset, kanye nokusatshalaliswa, matrix oqinile wezinto ze-thermoplastic. Umphumela uthola izakhiwo ezivela kuzo zombili izingxenye kodwa uyakwazi ukucutshungulwa ngokunemba okwedlulele emishini yokubumba yomjovo. Ngeminye imininingwane, bheka umhlahlandlela wethu kulokho irabha le-thermoplastic.

Ama-rubbers ajwayelekile ahlanganisiwe noma acwengeke ngendlela ethile ye-polymerized, bese kufakwa ukushisa ukuze uqedele inqubo yokuxhumanisa. Endabeni ye-TPR, i-Buteinee nto yokwenziwa ixhumeke ngokuphelele futhi ikhiqizwe njengempuphu enhle. Ingxenye ye-PS Bese efaka esikhundleni sokuxhumeka kwesiphambano ngokubopha irabha ku-matrix eqinile ye-polymer. Imiphumela yokuvumelana nezimo kusuka ekubumbeni kwengxenye ye-batediene, lapho isibopho senjoloba se-intra-esiyizinhlayiyana empeleni sine-innastic.

I-TPR ayihambelani nokusebenza kwama-rubber avundwayo, ngakho-ke ayilungele ukukhiqizwa kweTire, enesivinini esikhulu kakhulu se-modulus. Kodwa-ke, i-ozone engcono kakhulu-, isimo sezulu esiphakeme-, kanye nezakhiwo ezivimbela i-TPR ezisho ukuthi zithola ukusetshenziswa okubanzi emikhakheni eminingi yomkhiqizo.

Yini i-tPU?
I-TPU polymers yenziwe ngezakhiwo ezivinjelwe ezinde, [ezithambile "ze-polarization ephansi, nezingxenye ezimfushane, [ezinzima" zokukhala okuphezulu kakhulu. Ukuxhumana okuzenzakalelayo phakathi kwalezi zingxenye ezimbili zenza amaketanga ahlanganiswe kahle athola izakhiwo ezivela ezintweni zombili ze-chain. Ngokushintsha izinsimbi zamangqamuzana nezilinganiso zezingxenye zezindawo, izinhlobonhlobo zezakhiwo zingatholwa ngezinto ezifanayo zamakhemikhali (cishe). Amazinga okushisa aguqukayo engilazi yezakhi ezimbili angaba afanayo noma ahlukaniswe, futhi angashintshwa ngamakhemikhali ukuze abe ngaphezulu noma aphansi. Lezi zinkinga zokucubungula zivumela ukukhiqizwa kwezakhiwo ezahlukahlukene ze-thermal zomndeni wezinto ezibonakalayo.

I-polarization ephakeme yezakhi ezinzima idonsa ukuheha okunamandla, okufumana izifunda ze-pseudo-crystalline, ezitholakala ku-matrix elastic kakhulu. Izifunda ze-Pseudo-Crystalline ziziphatha njengezakhi ezixhumanisayo, okuyi-akhawunti ye-modulus ephezulu yomndeni, kanti amaketanga amade, athambile alinganise ngalo mphumela, ukuvumela ubulukhuni obuhlukahlukene.

Lo mphumela wokuxhuma ngokuwela uncipha ku-zero njengoba izinga lokushisa lengilazi lengxenye yengxenye enzima lidluliwe. Umndeni uziphatha njengeqembu elibonakalayo le-thermoplastic elingase licutshungulwe emishini yokuhlanganisa yokujoyina ejwayelekile. I-TPUS ingavuselelwa kabusha ngokuncibilikisa nokuguqula izinguquko, yize ukucekelwa phansi kwe-chain ubude / ubuqotho kubalulekile ekufezeni.

I-TPR vs. TPU: Izicelo kanye nokusebenzisa
Kufakwe ohlwini ngezansi yizimboni ezijwayelekile kanye nezicelo ezijwayelekile ze-TPR:

Izicathulo zezinyawo nemishini yezemidlalo: Ukudonswa kwezinyawo, ama-snorkels, imaski, ski-pole grips, izingxenye ze-ski-boot, kanye nezinto zezicucu.
Kufakwe ohlwini ngezansi yizomkhakha ezijwayelekile kanye nezicelo ezijwayelekile ze-TPU:

Izithuthi: izingxenye zezimoto ezingaphakathi (ukuqedwa kwendawo enhle, ukuqina, ukumelana kokuqina; nezindleko eziphansi).
Ezolimo: Amathegi we-ID ezilwane (ukuguquguquka okukhulu, ukuguquguquka nokuphikisana kwesimo sezulu, nokubekezelela izinga lokushisa. Kuhle ukuhlanganisa i-RFID).
Amapayipi kanye namapayipi: Amaphrofayili we-Seal kanye nama-O-ring, amashubhu, amabhande kanye nama-hoses. Ama-polymers akhethekile anezakhiwo ezi-actical-flow-flow-flow, ukuvumelanisa okuvumelaniswe nge-hydrolysic namanye amafutha kanye nama-organics, ukumelana nokucindezela emazingeni okushisa aphezulu, ukuqina okuphezulu, ukuguquguquka, kanye nokumelana nokudwengula.
Indwangu: Isetshenziselwa amabhande okuhambisa, ama-inflatatables, kanye nemishini yezempi. Uhla olubanzi lwezinketho zokucubungula, kanye nezakhiwo ezinhle zemishini, zamakhemikhali, kanye ne-thermal.
Imishini Yezemidlalo: Ukuguquguquka okwedlulele, ukumelana nomthelela omkhulu kanye nokumelana nokushisa, ukucaca, kanye nokubekezelelana kwemvelo.
Kunemikhakha evamile yemakethe kanye nezindawo zomkhiqizo ezijwayelekile ezingasebenzisa noma izinsiza ze-TPR noma ze-TPU. Ngokuvamile, izinto ezijwayelekile azisho ukuthi ukuguquguquka kokuhlangana, njengoba isicelo ngasinye sivame ukuxhaphaza impahla emincane noma enye into. Isibonelo, umkhakha wezimoto uvame ukusebenzisa ama-TPRS ngokuguquguquka okwedlulele kanye nezinto ezisetshenziswayo, ne-TPUS yokuqina, ukugqokwa kokugqoka, kanye nezicelo ze-ergonomic

I-TPR vs. TPU: Ukuvuselelwa kabusha kanye nokusimama
Zombili lezi zinto zithathwe emithonjeni ye-petrochemical, futhi ukuqina kwazo kanye nokuvuselela kabusha iziqinisekiso kufana. I-TPU iphinde iphinde isebenze; Ukungcola kwayo kungahle kucutshungulwe emuva kokuqukethwe okulinganiselayo okuphezulu. Noma, kuvame ukuba yibanga lesibili ngenxa yokuwohloka okushisayo. I-TPU nayo iyabonakala futhi izokwehla ngokuvamile ekugcwalisweni komquba / izimo zomquba ngaphezulu kweminyaka emi-3-5. Akushiyi izinsalela ezinobuthi lapho zehlela phansi. I-TPUS futhi iyatholakala kancane futhi ingenziwa kumaMonomers ane-bio-apholile.

I-TPR ibuye iphinde isebenze kabusha, kepha njengama-polymers amaningi, impahla esetshenzisiwe yesesibili. Ziyizinto ezizinzile ezingcolisa kancane kakhulu endaweni yemvelo. Izinto zomthombo we-algal ezisuselwa kuma-monomer ze-TPRS nazo ziyatholakala.

I-TPR vs. TPU: Izindleko
Ama-TPRS ngokuvamile anezindleko eziphansi kakhulu, ebangeni lama- $ 1.60 kuya ku- $ 2.00 nge-kg ngalinye. I-TPUS ibiza kakhulu, ngo- $ 2.00 kuya ku- $ 4,00 nge-kg.

Ezinye izinto zokwakha ku-TPR ne-TPU
Ukusetshenziswa kokubumba kokujoyina, izinto ezahlukahlukene ze-thermoplastic elastomeric zitholakala, ngokubumba okubanzi okulinganayo kwezindawo nezindleko. Ngenkathi lokhu kungaguquki kulo lonke uhla lonke, kunezilinganiso eziningi zezakhiwo eziholela ekukhetheni esigabeni esicacisiwe. Kufakwe ohlwini ngezansi ezinye izinto ezihlukile:

I-Thermoplastic Vulcalisates (TPE-V noma i-TPV).
I-Thermoplastic polyolefins (TPE-O noma i-TPO).
I-Thermoplastic Copolyyers (TPE-E, Cope, noma Teee).
I-Thermoplastic polyther block ardedes (TPE-a).
I-Styrenic block Copolymers (TPE-S).
Ukuncipha okusebenzayo kwerabha (MPR).
I-fluoropolymer lastomers (FPE).
Lapho ukushintshela kuma-armosetting polymers kuyinto inketho, kunezinketho eziningi ezibonakalayo, njengoba kubhalwe ngezansi:

I-Vutecanized Rubber yemvelo (NR) (i-latex, i-Vulcanled ukwakha irabha le-buna).
I-PolyiSoprene (IR).
Polychlororoprene (CR).
I-Buthadien Rubber (BR).
Nitrile (buthadiene) irabha (i-NBR).
I-TheROSET RUBBERS iletha izakhiwo ezintsha kanye nemikhawulo emisha kuhlu lwezinketho. Bangakwazi, noma kunjalo, bazuze imiphumela emangalisayo noma nini lapho kufunwa izakhiwo ezithile futhi nezinkinga zokucubungula azivimbi ukusetshenziswa.
