TPP TPU

TPR kapena mphira wa thermoplaclastic imakhala yopukusira yomwe imaphatikiza kuti katundu wa polystyrene (PS) ndi butadiene (chopangira). Izi zidapangidwa kuti zithandizireni katundu wambiri wopangira mphira pomwe akulola kukonza (ndikubweza) munthawi yokhazikika komanso yolamulira. TPR imapereka kutopa kwakukulu, kukhazikika kwamankhwala, kumakhudza mphamvu, ndikubwezeretsa mwatsatanetsatane, ndikukonzekera koyenera.

TPU kapena polmoplastic polyirethane ndi gulu lonse la polinthane yomwe imagawana katundu monga: kutopa, kuwonekera, kuvala mokhazikika, komanso kukana mafuta. Zipangizozo ndi za thermoplastic, ndi magawo osiyanasiyana a elastomeric. Mphamvu zawo zazikulu komanso kulimba zimachokera ku mawonekedwe a polymer okhala ndi njira zosinthira zovuta komanso zofewa.

Nkhaniyi ikufanananso ndi TPS Vs. TPU, ntchito zawo, kugwiritsa ntchito, zinthu zakuthupi, ndi zinthu zina.

Kodi TPR ndi chiyani?
TPR (rabay wa thermoplastic) nthawi zambiri zimakhala ndi zophatikiza 23% PS ndi 77% bunadiene. Yakonzedwa ndi emulsion polymerization wa opanga ma polima. Njirayi imapangitsa zinthu zosawerengeka zomwe zili ndi gawo la elastomeric, mtondo, komanso matrix a matrix a thermoplastic zinthu. Zotsatira zake zimayambira zinthu kuchokera ku zigawo zonsezi koma zimatha kuphatikizidwa molondola kwambiri m'magulu owumba jakisoni. Kuti mumve zambiri, onani kalozera wathu pa mphira wa thermoplastic.

Ma ruble okhazikika amapangidwa kapena kuyesedwa mu mawonekedwe osakhazikika, kenako kutentha kumayikidwa kuti amalize njira yolumikizira. Pankhani ya TPR, gawo la butadiene lapangidwa mokwanira ndipo limapangidwa ngati ufa wabwino. Gawo la PS ndiye choloweza mmalo mwa kulumikizana mwa kugwirizanitsa mphira mu matrix olimba a polymer. Kusinthasintha kumapangitsa kuti kusokonekera kwa gawo la a bunadiene, komwe kulumikizana kwa mphira-time-tinthu ndikosasinthika.

Tph sikufanana ndi magwiridwe antchito opukutira, chifukwa chake sioyenera kupanga matayala, kukhala ndi misozi yotsika kwambiri. Komabe, nyengo yabwino kwambiri ya ozoni-, ya UV-UV-UV imatanthawuza kuti imapeza ntchito zambiri pamagawo ambiri azogulitsa.

TPU ndi chiyani?
TPU ma polima amapangidwa ndi zigawo zokhala ndi zigawo zazitali, zofewa "za polarization yotsika, komanso zazifupi Ulalo wogwirizana pakati pa magawo awiriwo amapanga maunyolo ophatikizika omwe amachokera ku zinthu kuchokera ku zinthu zonse ziwiri. Posintha zolemera za maselo ndi zigawo za malo opanga, mitundu yambiri imatha kutengera zinthu zomwe zimachitika (pafupifupi) zofananira. Kutentha kwagalasi Kusinthitsa kwa zinthu ziwirizi zitha kukhala zofanana kapena zotupa, ndipo zimatha kukhala zapamwamba kukhala zapamwamba kapena zotsika. Nkhani zosintha izi zimalola kupanga mitundu yamafuta osiyanasiyana pazomwe zimachitika.

Kukula kwakukulu kwa zinthu zovuta kumapangitsa kukopa kwamphamvu, komwe kumapangitsa madera a preeudo-crystalline, komwe kumachitika ku matrix. Madera a Pseudo-Crystalline amakhala ngati zinthu zolumikizirana, zomwe zimawerengetsa maunyolo kwambiri a banjali, pomwe ofewetsa minyo yayitali amasintha izi, kulola kuvuta kwamphamvu / kupangika kupangidwa.

Mphamvu yolumikizirana iyi imachepa mpaka zero pamene kutentha kwagalasi kumachitika kovuta. Banja limakhala loti gulu lankhondo la andrmoplastic lomwe limatha kukonzedwa m'magulu wamba owumba. TPus itha kubwezeretsedwanso ndikusungunuka ndikusintha, ngakhale kuwonongeka kwa kutalika / umphumphu ndikofunikira pakukumbukira.

TPR vs. TPU: Ntchito ndi kugwiritsa ntchito
Kulembedwa pansipa ndi mafakitale wamba komanso njira zodziwika bwino za TPR:

Kupanga Auto: Khomo ndi Zisindikizo za pawindo, kufalitsa / kuyimitsidwa, mapangidwe am'mimba, ma acs, mapaipi apansi, matope apansi.
Ntchito yomanga: Khomo ndi Zisindikizo zawindo, zisindikizo zam'manja, Zisindikizo Zopaka.
Kufalikira: Mapaipi akupondaponda, mapaipi, kuwonongedwa, Zisindikizo, tchire kuyimitsidwa, kuwoneka bwino, ma membranes.
Wogula: firiji Zisindikizo, zopitilira pamanja zopitilira muyeso, mafoni am'manja, sinthani mapanelo, kugwedezeka.
Zachipatala: Machubu a mpweya, syringes zisindikizo, masks opumira ndi ma shelnoms, zisindikizo, ma valves, ndi ma catheters.
Magetsi: Zolemba, mphamvu zimatsogolera, zingwe zapamwamba kwambiri, kuteteza foni yam'manja, ndi zisindikizo.
Zida za nsapato & zamasewera: zojambulajambula, zotupa, masks, ski-pope, maboti a boot, ndi mawonekedwe a nsapato.
Kulembedwa pansipa ndi mafakitale wamba komanso njira wamba TPU:

Magetsi: Magawo a amayi oyenda bwino (abwino kumapeto, kulimba, kuvala kukana; ndi mtengo wotsika).
Agriculture: ID tags for animals (great flexibility, tear and weather resistance, and temperature tolerance. Great for encapsulating RFID).
Kupukutira ndi Kupaka Mindandanda: Zisindikizo zamitundu ndi mabatani, machubu, malamba, ndi hoses. Katswiri polima ma polima okhala ndi zotumphukira, kuchepa kwamphamvu kwambiri ku Hydrolysic ndi mardraulic ndi mafuta ndi zinthu zambiri, kusinthana, ndi kukana kung'amba.
Zolemba: Ntchito zogwirizira malamba, zowoneka bwino, komanso zida zankhondo. Mitundu yosiyanasiyana yopanga njira, komanso makina abwino, mankhwala, ndi mafuta.
Zida zamasewera: Kusinthasinthasintha kwambiri, mphamvu zapamwamba komanso kutentha kwa kutentha, kuwonekera, ndi kulolera zachilengedwe.
Pali magawo ambiri amisika komanso madera wamba odziwika omwe amatha kugwiritsa ntchito zida za TPP kapena TPU. Mwambiri, zomwe zimachitika sizitanthauza kusinthana, pamene ntchito iliyonse imakonda kugwiritsa ntchito katundu wopapatiza wa chinthu chimodzi kapena china. Mwachitsanzo, gawo lamagalimoto limagwiritsa ntchito ma tprs pakusintha kwambiri komanso kuthengo, ndi ma tpus pakukhazikika, kuvala kukana, ndi ntchito za ergonomic

TPR vs. TPU: Kubwezeretsanso ndi kukhazikika
Zipangizo zonsezi zimachokera ku matenda a petrochemical, ndipo chitsimikizo chawo komanso chitsimikiziro chobwereza ndi chofanana. TPU ikukonzedwa kwambiri; Zinyalala zake zimatha kukonzedwanso m'malo apamwamba. Ngakhale, zimakonda kukhala kalasi yachiwiri chifukwa cha kuwola kwa mafuta. TPU ilinso biodegrad ndipo nthawi zambiri imakhala yopuma / kompositi zaka 3-5. Simasiya zotsalira pakapita nthawi ikasweka. TPus imapezekanso pang'onopang'ono ndipo imatha kupangidwa kuchokera ku monoments yopingasa.

TPR imawerengedwanso, koma monga ma poizo ambiri, zinthu zobwezerezedwanso ndi kalasi yachiwiri. Ndi zinthu zokhazikika zomwe zimagwedezeka pang'onopang'ono m'chilengedwe. Zinthu zodzitchinjiriza za Algal-zochokera ku ma tprs zikupezekanso.

TPR vs. TPU: mtengo
TPRS nthawi zambiri imakhala yotsika mtengo kwambiri, pamtundu wa $ 1.60 mpaka $ 2.00 pa kg. TPus ndiokwera mtengo pang'ono, pa $ 2.00 mpaka $ 4.00 pa kg.

Zowonjezera zina kwa TPR ndi TPU
Kwa kugwiritsa ntchito jakisoni wogwiritsa ntchito jakisoni, mitundu yosiyanasiyana ya mafuta a Thermoplastic imapezeka, ndi mawonekedwe ofanana ndi katundu ndi mtengo. Ngakhale izi sizimasinthika kudutsa gawo lonse, pali zinthu zambiri zomwe zimapangitsa kuti zisachitike m'njira yoyerekeza. Kulembedwa pansipa ndi zinthu zina zosankha:

Thermoplac impcanisis (Tpe-V kapena TPV).
Thermoplastins polyolefins (Tpe-O kapena TPE).
Thermoplastic Copvolters (Tpe-e, kupirira, kapena teee).
Thermoplastic Polythether block Amide (Tpe-a).
Stynic block Coptolmers (TP-S).
Rate-forthala (MPR).
Fluoropolymer elastomers (FPE).
Mukasintha kwa thermoseting ma polima ndi njira, pali zosankha zambiri zakuthupi, monga zalembedwera pansipa:

Vercankid mwachilengedwe (nr) (latx, oyipitsidwa kuti apange buna rabara).
Polysoprene (IR).
Polychloroprene (Kr).
Buradine rabara (BR).
Nitrile (butadiene) mphira (NBR).
Opukuta a thermonkhot amabweretsa katundu watsopano komanso zoletsa zatsopano pamndandanda. Atha, komabe, kukwaniritsa zotsatira zabwino nthawi iliyonse malo azomwe amafunidwa ndipo makonzedwe osakonzekera saletsa kugwiritsa ntchito.
