Izindaba - Susa i-TPU Peeling ku-Nylon Overmolding nge-Si-TPV, Izinto Ezifanele Zokunethezeka Ezithambile Nezinobungane Nesikhumba Zokumboza I-Nylon

Susa Isixazululo Esiqinile Se-Nylon Si-TPV 3525-65A Overmolding

Kungani Ukubumba Okuthambile Ku-Nylon Kubaluleke Kangaka?

Inayiloni, njengepulasitiki yobunjiniyela, isetshenziswa kabanzi ezinhlotsheni ezahlukene ngenxa yezakhiwo zayo ezinhle kakhulu zemishini. Kodwa-ke, ubuso bayo obuqinile buvame ukuholela ekuhlangenwe nakho okungekuhle kokuthinta kanye nokuklwebheka kwesikhumba okungenzeka ngesikhathi sokuxhumana komuntu. Ukuze kulungiswe lokhu, ama-elastomer athambile anobunzima be-Shore obusukela ku-40A kuya ku-80A (ngokuvamile u-60A ~ 70A) ahlanganiswa phezu kwezingxenye ze-nylon, ahlinzeka ngokuvikelwa okunobungani nesikhumba, induduzo ethuthukisiwe yokuthinta, kanye nokuguquguquka okukhulu komklamo.

Izindlela zendabuko zokubopha ngokomzimba (isb., imiklamo yokulingana, ukugoqa, noma izindawo ezinezintambo) zokubopha i-nylon zihlushwa amandla okunamathela angaguquki kanye nenkululeko yokuklama elinganiselwe. Ngokuphambene nalokho, ukubopha kwamakhemikhali kusebenzisa ukunamathela kwama-molecule, i-polarity, noma ukubopha kwe-hydrogen phakathi kwezinto, okuqinisekisa ukunamathela okufanayo kuyo yonke indawo futhi kuvumela amajiyometri ayinkimbinkimbi.

Izithiyo Zokusebenzisa i-TPU Ekubumbeni Nge-Nylon Overmolding

I-Thermoplastic Polyurethane (TPU) isetshenziswa kabanzi ekubumbeni i-nylon ngenxa yokumelana kwayo nokuguguleka kanye nebhalansi enhle yemishini. Ivame ukubhekwa njengehambisana ne-nylon ngenxa ye-polarity yayo efanayo. Kodwa-ke, i-TPU ivame ukuba nenkinga yokunamathelana okungekuhle phakathi kwe-interfacial, okuholela ekuqhekekeni noma ekuqhekekeni, ikakhulukazi ezimweni zokucindezeleka okukhulu noma ezisetshenziswa isikhathi eside.—ekugcineni kwehlisa ikhwalithi kanye nokusebenza komkhiqizo.

Isixazululo:Kwethulwa i-Si-TPV 3525-65A, enye indlela ye-TPU, i-elastomer engcono kakhulu yokwenza i-nylon overmolding

Ukuze kulungiswe imikhawulo ye-TPU, i-Silike ithuthukise i-Si-TPV 3525-65A—i-silicone-thermoplastic vulcanizate elastomer egcina izakhiwo ezifiselekayo ze-TPU ngenkathi ithuthukisa kakhulu ukunamathela ezisekelweni ze-nylon.

Lokhuizinto ezintsha ze-thermoplastic elastomer ze-Si-TPV ezithambileokunikezwayo:

1. Ukubopha kwamakhemikhali okuhle kakhulu ne-PA6, PA12, kanye ne-PA66

2. I-interface eqinile, efanayo yokubumba

3. Indawo ethambile enokududuzeka okuthuthukisiwe komsebenzisi

4. Ukuqina okumangalisayo kwemishini, amanzi, ukumelana namafutha, kanye nokuguquguquka kokubanda

Ukusebenza Okuphezulu Kokubumbana kwe-Si-TPV 3525-65A kuma-Nylon Substrates, Ucwaningo Lokuqhathanisa ne-TPU Lokuqinisa Ukubopha kanye Nenduduzo Yokuthinta!

Ukuhlola Ukunamathela: Ukuhlolwa Okujwayelekile Kokubumba Okujwayelekile

Ukuze kuqhathaniswe ukusebenza kwe-bonding, i-Si-TPV kanye ne-TPU kwahlolwa kusetshenziswa inqubo ejwayelekile yokubumba ngaphezulu:

Izisekelo ze-nylon (PA6) zabunjwa ngomjovo, zabe sezisikwa ngokuvundlile ku-45° bese zipholishwa ngephepha lesihlabathi elingu-120-grit.

Ama-substrate aphathwe aphinde afakwa ezikhumbeni ukuze zibunjwe ngaphansi kokushisa okulawulwayo kanye nengcindezi.

Kwenziwe ukuhlolwa kokuqina ukuze kuhlolwe amandla okubopha phakathi kwe-interfacial.

I-TPU vs. I-Si-TPV 3525-65A ku-PA6: Imiphumela Yokuhlolwa Kwamandla Okucindezela Ekuphumuleni Nasekunamatheleni

Thuthukisa Umklamo Womkhiqizo Wenayiloni Nge-Soft-Touch Overmolding Ngezixazululo ze-Si-TPV 3525-65A

Ukuhlanganiswa Okuphakeme ku-PA6, PA12, kanye ne-PA66, i-Si-TPV 3525-65A Kuchazwe Ukusebenza Kokunamathela

Ukubumbana kwe-TPU kuma-substrate e-PA:

Njengoba ubulukhuni be-TPU bukhula (60A kuya ku-90A), amandla okubopha ku-PA6 ehla kakhulu. Ku-90A, i-TPU yehlulekile ukubopha ngokuphelele.

I-Si-TPV 3525-65A Overmolding, enye indlela ye-TPU yokwakheka kwe-nylon overmolding:

Kubonise ukubopha okuqinile nokungaguquguquki ne-PA6. Ukuhlaziywa kwesigaba esiphambene kwembule ukwehluleka kokubambisana—i-Si-TPV yahlala inamathele kuzo zombili izinhlangothi zesixhumi esibonakalayo, okufakazela ukubopha okuqinile kwamakhemikhali. Ngokuphambene nalokho, izixhumi ezixhunyanisiwe ze-TPU zibonise insalela encane, okubonisa ukunamathela okubuthakathaka.

Izinto ezithambile ze-Si-TPV 3525-65A kuzo zonke izinhlobo ze-Nylon Grades: Ezithembekile Kuyo yonke i-PA6, i-PA12, i-PA66

I-Modified Silicone Elastomer 3525-65A iphinde yathola ukubopha okuqinile ezinhlotsheni eziningi ze-nylon.

I-Non-Sticky Thermoplastic Elastomer Si-TPV 3525-65A ku-PA12, ukubumbana okungaphezulu akubonisi ukuhlukana okubonakalayo ngesikhathi sokuhlolwa, okuqinisekisa ukubopha okuqinile ngaphandle kokwehluleka kwe-interface.

Ama-Elastomer angenapulasitiki i-Si-TPV3525- 65A ku-PA66, izinto zokwakha zigcine ukunamathela okuqinile kanye nobuqotho besakhiwo ngaphansi komthwalo.

(Qaphela: Zonke izindinganiso zokuqina kwe-Shore kanye nezinqubo zokuhlola ziyahambisana nezindinganiso zomhlaba wonke zokuhlola i-elastomer kanye nokunamathela.)

Sala kahle i-TPU Peeling – Thuthukela ku-Si-TPV Enobungani Nesikhumba, Ethambile Yokuthinta Ukuze Usebenzise I-Nylon Overmolding Eqinile

I-Si-TPV 3525- 65A ihlanganisa ukuqina kwe-TPU ngokuthinta okuthambile kanye nokunamathela kwamakhemikhali kwe-silicone. Inikeza isisombululo esiphumelelayo sokubumba izingxenye ze-nylon ezisetshenziswa kuma-electronics abathengi, ngaphakathi kwezimoto, kanye namathuluzi ezimboni.

Ngokushintshela ku-Si-TPV, abakhiqizi bangaqeda izinkinga zokuxebuka kwe-TPU, bandise isikhathi sokuphila komkhiqizo, balethe ukuphepha, ubuhle, kanye nokusebenza okuhle kakhulu.
