Izindaba - Izixazululo Zezinselele Ezivamile Zokubumba Okungaphezu Kokubumba Nokuphakamisa Induduzo, Ubuhle Nokuqina Komklamo Othambile

Ukuvela: Ukubumba Okungaphezulu kwe-TPE

I-TPE, noma i-thermoplastic elastomer, iyinto eguquguqukayo ehlanganisa ukuqina kwerabha nokuqina kwepulasitiki. Ingabunjwa noma ikhishwe ngqo, nge-TPE-S (i-styrene-based thermoplastic elastomer) evame ukusetshenziswa, ifaka ama-SEBS noma ama-SBS elastomer epulasitiki yobunjiniyela be-thermoplastic. I-TPE-S ivame ukubizwa ngokuthi i-TPE noma i-TPR embonini ye-elastomer.

Kodwa-ke, i-TPE overmolding, eyaziwa nangokuthi i-thermoplastic elastomer overmolding, inqubo yokukhiqiza ehilela ukubumba izinto ze-thermoplastic elastomer (TPE) phezu kwe-substrate noma izinto eziyisisekelo. Le nqubo isetshenziselwa ukuhlanganisa izakhiwo ze-TPE, njengokuguquguquka kwayo kanye nobumnene, nezici ezithile ze-substrate engaphansi, okungaba yipulasitiki eqinile, insimbi, noma enye into.

Ukubumba i-TPE kuhlukaniswe izinhlobo ezimbili, enye iwukubumba kwangempela kanti enye iwukubumba mbumbulu. Imikhiqizo yokubumba i-TPE ngokuvamile iyimikhiqizo yezibambo nezibambo, ngenxa yokuthinta okukhethekile okukhululekile kwezinto zepulasitiki ezithambile ze-TPE, ukwethulwa kwezinto ze-TPE kuthuthukisa ikhono lokubamba lomkhiqizo kanye nomuzwa wokuthinta. Isici esihlukanisayo yindlela izinto zokubumba i-overmolding ezisetshenziswa ngayo, ngokuvamile ukusebenzisa ukubumba okufakwe imibala emibili noma ukubumba kwesibili kokumboza ipulasitiki kuyi-overmolding yangempela, kuyilapho i-shot sticking overmolding yensimbi kanye nezinto zendwangu kuyi-overmolding mbumbulu, emkhakheni wokubumba i-overmolding yangempela, izinto ze-TPE zingahlanganiswa namapulasitiki athile ajwayelekile, njenge-PP, i-PC, i-PA, i-ABS njalo njalo, anokusetshenziswa okubanzi.

Izinzuzo zezinto ze-TPE

1. Izakhiwo Ezingasheleli: I-TPE inikeza indawo engasheleli ngokwemvelo, ithuthukisa ukusebenza kokubamba kwemikhiqizo ehlukahlukene njengezibambo zeklabhu yegalofu, izibambo zamathuluzi, izibambo zamazinyo, kanye ne-TPE phezu kwemishini yezemidlalo ebunjiwe.
2. Ubumnene kanye Nenduduzo: Uhlobo oluthambile lwe-TPE, uma lusetshenziswa njengengqimba yangaphandle ezintweni zerabha eziqinile, luqinisekisa umuzwa okhululekile futhi onganamatheli.
3. Ububanzi Bokuqina: Njengoba ububanzi bokuqina buvame ukuba phakathi kuka-25A-90A, i-TPE inikeza ukuguquguquka ekwakhiweni, okuvumela ukulungiswa kokumelana nokuguguleka, ukuguquguquka, nokuningi.
4. Ukumelana Nokuguga Okumangalisayo: I-TPE ikhombisa ukumelana okunamandla nokuguga, okunegalelo ekudeni kwesikhathi eside kwemikhiqizo.
5. Ukwenza Umbala Ngokwezifiso: I-TPE ivumela ukwenza umbala ngokwezifiso ngokungeza ufulawa wombala noma i-masterbatch yombala ekwakhiweni kwezinto.
6. Ukumuncwa Kokwethuka kanye Nezakhiwo Zokungangenwa Yimanzi: I-TPE ibonisa amakhono athile okumuncwa kokuthuthumela kanye nokungangenwa yimanzi, okwenza ifaneleke ukubopha ezindaweni ezifiselekayo futhi isebenze njengento yokuvala.

Izimbangela Zokubumba Okungavikelekile kwe-TPE

1. Ubunzima bokuhlaziywa kokubumbana kwepulasitiki: amapulasitiki asetshenziswa kakhulu yi-ABS, PP, PC, PA, PS, POM, njll. Uhlobo ngalunye lwepulasitiki, ngokuyisisekelo lunezinga lezinto ezihambisanayo ze-TPE ovemolding. Uma sikhuluma ngokujwayelekile, i-PP iyona engcono kakhulu yokusonga; i-PS, ABS, PC, PC + ABS, PE plastic wrapping yesibili, kodwa ubuchwepheshe bokusonga nabo buvuthiwe kakhulu, ukuze kufezwe i-ovemolding eqinile ngaphandle kobunzima; ubunzima be-ovemolding ye-nylon PA buzoba bukhulu, kodwa eminyakeni yamuva nje ubuchwepheshe buthuthuke kakhulu.

2. Ububanzi obukhulu bokubumba kwe-TPE yepulasitiki: Ubunzima bokubumba kwe-PP bungu-10-95A; Ukubumba kwe-PC, i-ABS kusuka ku-30-90A; Ukubumba kwe-PS kusuka ku-20-95A; Ukubumba kwe-PA ye-nylon kungu-40-80A; Ukubumba kwe-POM kusuka ku-50-80A.

Izinselele kanye nezixazululo ku-TPE Overmolding

1. Ukubeka nokususa: Thuthukisa ukuhambisana kwe-TPE, lungisa isivinini somjovo kanye nokucindezela, futhi ulungise usayizi wesango.

2. Ukudilizwa Okubi: Shintsha izinto ze-TPE noma ufake okusanhlamvu kwesikhunta ukuze kunciphe ukukhazimula.

3. Ukumhlophe Nokunamathela: Phatha amanani okwengezwayo ukuze ubhekane nokukhishwa kwegesi kwezithasiselo ezincane zama-molecule.

4. Ukuguqulwa Kwezingxenye Zepulasitiki Eziqinile: Lungisa izinga lokushisa lomjovo, isivinini, kanye nokucindezela, noma uqinise isakhiwo sesikhunta.

Ikusasa: Impendulo ye-Si-TPV Ezinseleleni Ezivamile Zokubumba Okungaphezu Kokubunjwa Ukuze Kukhange Ubuhle Okuhlala Njalo

Kubalulekile ukuqaphela ukuthi ikusasa lokubumba ngokweqile liyashintsha ngokuhambisana okuhle kakhulu nezinto ezithambile!

Le elastomer entsha esekelwe ku-thermoplastic silicone izokwenza kube lula ukubumba okuthambile kuzo zonke izimboni okunethezekile nokujabulisayo.

I-SILIKE yethula ikhambi eliyingqayizivele, i-elastomers esekelwe ku-thermoplastic Silicone (efushane nge-Si-TPV), edlula imingcele yendabuko. Le nto ihlanganisa izici eziqinile ze-thermoplastic elastomers nezici ze-silicone ezifiselekayo, inikeza ukuthinta okuthambile, umuzwa othambile, kanye nokumelana nokukhanya kwe-UV namakhemikhali. Ama-elastomers e-Si-TPV abonisa ukunamathela okumangalisayo ezindaweni ezahlukene, egcina ukucutshungulwa njengezinto ze-TPE ezivamile. Asusa imisebenzi yesibili, okuholela emijikelezweni esheshayo kanye nezindleko ezincishisiwe. I-Si-TPV inikeza umuzwa othuthukisiwe ofana nerabha ye-silicone ezingxenyeni eziqediwe ezibunjiwe ngokweqile. Ngaphezu kwezakhiwo zayo ezimangalisayo, i-Si-TPV yamukela ukusimama ngokuphinda isetshenziswe futhi isetshenziswe kabusha ezinqubweni zokukhiqiza zendabuko. Lokhu kuthuthukisa ubungane bemvelo futhi kunegalelo emikhubeni yokukhiqiza eqhubekayo.

Ama-elastomer e-Si-TPV angenayo i-plasticizer afanelekela imikhiqizo yokuthintana nesikhumba, ahlinzeka ngezixazululo kuzo zonke izimboni ezahlukahlukene. Ukuze kube nokubumba okuthambile kwemishini yezemidlalo, amathuluzi, kanye nezibambo ezahlukahlukene, i-Si-TPV inezela 'umuzwa' ophelele kumkhiqizo wakho, ikhuthaza ukusungula izinto ezintsha ekwakhiweni nasekuhlanganiseni ukuphepha, ubuhle, ukusebenza, kanye ne-ergonomics ngenkathi inamathela emikhubeni enobungani nemvelo.

Izinzuzo ze-Soft Overmolding nge-Si-TPV

1. Ukubamba Nokuthinta Okuthuthukisiwe: I-Si-TPV inikeza ukuthinta okuthambile nokunethezeka kwesikhumba isikhathi eside ngaphandle kwezinyathelo ezengeziwe. Ithuthukisa kakhulu ukubamba nokuthinta, ikakhulukazi ezibambweni nasezibambweni.

2. Induduzo Eyandisiwe Nokuzizwa Okumnandi: I-Si-TPV inikeza umuzwa ongaguquki omelana nokungcola, inciphisa ukumuncwa kothuli, futhi iqeda isidingo sama-plasticizer namafutha athambisayo. Ayivuthi futhi ayinaphunga.

3. Ukuqina Okuthuthukisiwe: I-Si-TPV ikhulisa ukumelana nokuklwebheka okuhlala isikhathi eside kanye nokuklwebheka, iqinisekisa ukuthi umbala uhlala isikhathi eside, ngisho noma ibhekene nokujuluka, uwoyela, ukukhanya kwe-UV, kanye namakhemikhali. Igcina ukubukeka kwayo okuhle, inikela ebude besikhathi somkhiqizo.

4. Izixazululo Zokubumba Ezihlukahlukene: I-Si-TPV izinamathela ngokwayo kumapulasitiki aqinile, ivumela izinketho ezihlukile zokubumba ngokweqile. Inamathela kalula kwi-PC, i-ABS, i-PC/ABS, i-TPU, i-PA6, kanye nezinye izinto ezifanayo ze-polar ngaphandle kokudinga izinamathiselo, ikhombisa amakhono akhethekile okubumba ngokweqile.

Njengoba sibona ukuvela kwezinto ezimbozwayo, i-Si-TPV ivelele njengamandla aguqulayo. Ubuhle bayo obungenakuqhathaniswa bokuthinta okuthambile kanye nokusimama kwenza kube yinto yesikhathi esizayo. Hlola amathuba, sungula imiklamo yakho, bese usetha amazinga amasha emikhakheni eyahlukene nge-Si-TPV. Yamukela inguquko ekumbozweni kokuthinta okuthambile - ikusasa selikhona manje!
