Izindaba - I-Si‑TPV Modifier Ithuthukisa Ukumelana Nokugqokwa Kwe-TPU Kwezinto Ezigqokwayo Ezihlala Njalo Nezithambile

I-TPU Gqoka Idivayisi Elastomer, Izinto Ezithambile Njengesikhumba Sewashi Lesikhumba, Izinto Ezigqokwayo Ze-elekthronikhi

Thuthukisa Ukumelana Nokugqokwa kwe-TPU: Izixazululo Zezinto Ezigqokwayo, Ikhebula, kanye Neminye Imikhiqizo Eqediwe

Emakethe yanamuhla yokuncintisana, i-thermoplastic polyurethane (TPU) isetshenziswa kabanzi ekusetshenzisweni okudingakalayo njengamajakethi ekhebula labathengi, amabhande ezimboni, izibambo ze-escalator, amabhande edivayisi agqokwayo, nezinye izingxenye eziguquguqukayo. Lawa macala okusetshenziswa awadingi nje kuphela izakhiwo eziqinile zemishini nezokunwebeka kodwa futhi nokumelana nokuguguleka okumangalisayo, futhi ezimweni eziningi, i-coefficient echaziwe yokungqubuzana.

Kodwa ama-OEM amaningi kanye nama-compounders athola ukuthi ngisho nama-TPU e-premium angahlushwa ukulimala kwendawo, ukuguguleka kokungqubuzana, ukuziphatha kokunamathela nokushelela, noma ukwehluleka ngaphambi kwesikhathi ngaphansi kwezimo zokugoba okujikelezayo.

Konjiniyela namaqembu okuklama, umbuzo obalulekile uba:Singakuthuthukisa kanjani ukuqina kwe-TPU ngaphandle kokubeka engcupheni ukuthamba, ukuqeda okubonakalayo, noma ukucutshungulwa kalula?

Izixazululo Zendabuko Nemikhawulo Yazo

Eminyakeni edlule, ama-compounders abhekane nezinkinga zokuguguleka kwe-TPU ngezindlela ezintathu eziyinhloko:
• Izithasiselo zokugcoba noma zokulwa nokungqubuzana — isib. i-PTFE, i-molybdenum disulfide, noma izinhlelo ezisekelwe ku-wax ezinciphisa ukungqubuzana kobuso kodwa ezingase zithuthe noma zithinte umuzwa wobuso.
• Izithako zokugcwalisa ezingagugi kakhulu — isib. izinhlayiya ze-ceramic noma ubuhlalu beglasi, ezingathuthukisa ukumelana nokuguguleka kodwa ngokuvamile zandisa ubulukhuni noma zinciphise ukuguquguquka.
• Izinhlelo zokuxhumanisa ezincane noma ezisabelayo — ezihlose ukukhiya isakhiwo futhi zimelane nokuguquguquka kwendawo, kodwa ngokuvamile ziphazamisa ukuphindeka kabusha noma ukwenza kube nzima ukujova/ukubumbana.

Ngayinye yalezi zindlela inezinzuzo, okuhlanganisa ukufuduka ngokuhamba kwesikhathi, ukuqhakaza kobuso, ukulahlekelwa ukuthamba, ukunciphisa ukuqeda kobuhle/ukuthinta isikhumba, noma izinkinga zokucubungula. Njengoba izinhlelo zokusebenza ziqhubeka zingena ezintweni ezigqokwayo, izintambo, kanye namaphrofayili amancane aguquguqukayo, kunesidingo esikhulayo somuguquli ogcina ukuguquguquka, ikhwalithi yobuso, kanye nokusebenza kokugqoka isikhathi eside.

Sethula Izindlela Ezintsha Nezisebenzayo Zokumelana Nokugqokwa Kwama-TPU Compounders

Intuthuko yakamuva kuma-elastomer asekelwe ku-silicone asebenzisa i-thermoplastic vulcanized thermoplastic(i-Si‑TPV) inikeza ikhambi elihlala njalo lokumelana nokuguguleka kwe-TPU, ukunqoba ukulinganiselwa kwezindlela zendabuko.

Le Thermoplastic Elastomer esekelwe ku-silicone yenziwe ngobuchwepheshe obukhethekile obuhambisanayo ukusiza irabha ye-silicone ukuthi ihlakazeke ku-TPU ngokulinganayo njengezinhlayiya ze-micron eziyi-1 ~ 3 ngaphansi kwe-microscope. Le nto eyingqayizivele ihlanganisa amandla, ukuqina, kanye nokumelana nokuguguleka kwanoma iyiphi i-thermoplastic elastomer nezakhiwo ezifiselekayo ze-silicone: ukuthamba, ukuzizwa okusilika, ukukhanya kwe-UV, kanye nokumelana namakhemikhali, okungaphinde kusetshenziswe futhi kusetshenziswe ezinqubweni zokukhiqiza zendabuko.

Ngokufaka inani elifanele le-Isiguquli se-Si‑TPV 3100-55Akuma-elastomer e-thermoplastic polyurethane (TPU), ama-compounders angafinyelela ukumelana okuthuthukisiwe kokuguguleka, ukuzinza okuthuthukisiwe komshini ngaphansi kokucindezeleka okujikelezayo, kanye nokuqeda okuthintekayo kwesikhathi eside okuthinta isikhumba okunomphumela we-matte—konke ngaphandle kwezithiyo ezivame ukuhlotshaniswa nama-lubricant, ama-hard fillers, noma izinhlelo zokuxhumanisa, njengokufuduka ngokuhamba kwesikhathi, ukuqhakaza kobuso, ukulahlekelwa ubumnene, noma ukuncipha kwezakhiwo zobuhle kanye nokuthinta isikhumba.

Ngokusho kwempendulo yamakhasimende, ukuhlolwa kwangaphakathi kukhombisa ukwehla kokulahlekelwa ukuguguleka okungaba ngu-30-75% kanye nokuthuthukiswa kokumelana nokuguguleka okungu-2-3× uma kuqhathaniswa nama-TPU ajwayelekile ngaphansi kwezimo zokuhlolwa kwenkampani—okudlula kakhulu ukusebenza kwama-TPU avamile angagugi emakethe.

Indlela i-Si‑TPV Enikeza Ngayo Ukumelana Nokugqokwa Okuhlala Njalo ku-TPU？

Izindlela Eziyinhloko Zokuguqula Ubuso Be-Si‑TPV Kuthuthukisa Ukuqina Kwe-TPU Nokusebenza Kokuthinta

Kusetshenziswa ubuchwepheshe obukhethekile bokuhambisana kanye ne-dynamic vulcanization, izinhlayiya zerabha ze-silicone (1–3 μm) zihlakazeka ngokulinganayo ngaphakathi kwe-TPU matrix, zakha isimo esiyingqayizivele "sesiqhingi solwandle". Lezi zinhlayiya ezinobukhulu be-micron zakha ama-micro-protrusions ebusweni be-TPU, zikhiqiza umuzwa othambile, obushelelezi, futhi onobungani nesikhumba.

Lesi sakhiwo sihlanganisa amandla okusebenza kanye nokuguquguquka kwe-TPU kanye nezakhiwo ezithintayo zerabha ye-silicone, kuyilapho kuqinisekiswa ukuthi izinhlayiya ze-silicone zihlala zisatshalaliswa ngokulinganayo nangokuzinzile ngaphakathi kwe-matrix.

Izinhlayiya zerabha ze-silicone ezivundile zithambile ngokwemvelo, zisebenza njengezingxenye ezithambile ze-thermoplastic elastomer, okunciphisa ubulukhuni be-TPU. Lokhu kuqeda isidingo sama-plasticizer angaphandle, kuvimbela izinkinga zokufuduka kukawoyela emthonjeni futhi kusekela ubuqotho bomphezulu wesikhathi eside ngenkathi kumelana nokunamathela komphezulu.

I-Si‑TPV iqukethe ingxenye enkulu yerabha ye-silicone exhumene ne-crosslinked enamandla aphansi omhlaba, okunciphisa i-coefficient of friction kanye ne-abrasion yezinto ezihlanganisiwe.

Ngenxa yokuthi irabha ye-silicone exhumene ayishukumi ngaphakathi kwe-TPU matrix ekushiseni kwegumbi, ukumelana kokuguguleka okubangelwayo kuhlala njalo futhi kuyafana, ngaphakathi nangaphandle.

Ngokungafani nezinto zokugcoba ezifudukayo njenge-linear siloxanes noma ama-waxes, alahlekelwa ukusebenza kahle uma ungqimba lwawo lokugcoba luphela, i-Si‑TPV inikeza ukumelana nokuguguleka okuhlala isikhathi eside.

Amathiphu Okusebenzisa Okusebenzayo: Hlanganisa i-Si‑TPV ku-TPU yakho eyisisekelo ngesilinganiso esilawulwayo (isb., indawo evamile yokuqala engu-5–10 wt%). Gcina izimo zokucubungula ezifana nesistimu yakho ye-TPU ukuqinisekisa ukusabalala okuhle.

Uma ungumuntu ohlanganisa izinto noma i-OEM ebhekene nezinselele zokuguguleka kwe-TPU—njengokukhathala kwe-cable flex, ukuguguleka kwendawo kanye nokunamathela kuma-Wearables, noma izinhlelo zokusebenza ezithambile eziguquguqukayo kakhulu—Izinto Zokuthinta Ezithambile Ezinobumnene Nezithambile Zesikhumba Ezihlala Isikhathi Eside Ezinobungane Nesikhumbaingakusiza:

• Ukunika ukumelana nokuguguleka okungapheli

• Gcina isiphetho esithambile nesinobungani nesikhumba esithintayo esinomphumela ongabonakali

• Ukucutshungulwa okulula

Thola ukuthi kanjaniama-elastomer e-thermoplastic anobungani nemvelo i-Si‑TPVingaphakamisa ukuqina nokusebenza kwemikhiqizo yakho ye-TPU.
