Nkhani - Zothetsera Zovuta Zowonjezereka Zowonjezereka ndikukweza Chitonthozo, Kukongola & Kukhalitsa mu Mapangidwe Ofewa

Chisinthiko: TPE Overmolding

TPE, kapena thermoplastic elastomer, ndi zinthu zosunthika zomwe zimaphatikiza kukhazikika kwa mphira ndi kulimba kwa pulasitiki. Itha kupangidwa kapena kutulutsa mwachindunji, ndi TPE-S (styrene-based thermoplastic elastomer) yomwe imagwiritsidwa ntchito kwambiri, kuphatikiza SEBS kapena SBS elastomers zamapulasitiki aukadaulo a thermoplastic. TPE-S nthawi zambiri imatchedwa TPE kapena TPR mumakampani a elastomer.

Komabe, TPE overmolding, yomwe imadziwikanso kuti thermoplastic elastomer overmolding, ndi njira yopanga yomwe imaphatikizapo kuumba thermoplastic elastomer material (TPE) pamwamba pa gawo lapansi kapena zinthu zoyambira. Njirayi imagwiritsidwa ntchito kugwirizanitsa katundu wa TPE, monga kusinthasintha kwake ndi kufewa kwake, ndi zizindikiro zenizeni za gawo lapansi, zomwe zingakhale pulasitiki yolimba, zitsulo, kapena zinthu zina.

TPE overmolding lagawidwa mitundu iwiri, wina ndi overmolding weniweni ndipo ina ndi yabodza overmolding. Zogulitsa zowonjezera za TPE nthawi zambiri zimakhala zogwirira ntchito komanso zogwirira ntchito, chifukwa cha kukhudza kwapadera kwa zinthu zapulasitiki zofewa za TPE, kuyambitsidwa kwa zinthu za TPE kumapangitsa kuti chinthucho chigwire komanso kukhudza. Chosiyanitsa ndi sing'anga ya zinthu overmolding, ambiri ntchito mitundu iwiri jekeseni akamaumba kapena yachiwiri jekeseni akamaumba kuphimba pulasitiki ndi overmolding weniweni, pamene kuwombera kumamatira overmolding zitsulo ndi nsalu zakuthupi ndi overmolding yabodza, m'munda wa kuchulukitsitsa kwenikweni, zinthu za TPE zitha kulumikizidwa ndi mapulasitiki ena onse, monga PP, PC, PA, ABS ndi zina zotero, zomwe zimagwiritsidwa ntchito mosiyanasiyana.

Ubwino wa TPE Material

1. Anti-Slip Properties: TPE imapereka malo osasunthika mwachilengedwe, kumathandizira kugwira ntchito kwazinthu zosiyanasiyana monga zogwirizira kalabu gofu, zogwirira zida, zogwirira mswachi, ndi TPE pazida zowumbidwa zamasewera.
2. Kufewa ndi Chitonthozo: Chikhalidwe chofewa cha TPE, chikagwiritsidwa ntchito ngati chingwe chakunja pazitsulo zolimba za mphira, zimatsimikizira kukhala omasuka komanso osakhazikika.
3. Wide Hardness Range: Ndi kuuma kosiyanasiyana pakati pa 25A-90A, TPE imapereka kusinthasintha pamapangidwe, kulola kusintha kwa kukana kuvala, kusungunuka, ndi zina.
4. Kukana Kukalamba Kwapadera: TPE imasonyeza kukana kwambiri kukalamba, zomwe zimathandiza kuti zinthu zikhale ndi moyo wautali.
5. Kusintha Kwamtundu: TPE imalola kusintha makonda mwa kuwonjezera ufa wamtundu kapena mtundu wa masterbatch pakupanga zinthu.
6. Mayamwidwe Odzidzimutsa ndi Zinthu Zosalowa Madzi: TPE imawonetsa kugwedezeka kwina ndi kuthekera kwamadzi, kupangitsa kuti ikhale yoyenera kulumikizana m'malo omwe mukufuna ndikugwira ntchito ngati chinthu chosindikizira.

Zomwe Zimayambitsa Kuchulukana kwa TPE kosatetezedwa

1.Kuvuta kwa kusanthula pulasitiki overmolding: pulasitiki amagwiritsidwa ntchito ndi ABS, PP, PC, PA, PS, POM, etc. Mtundu uliwonse wa pulasitiki, kwenikweni ali lolingana TPE ovemolding zinthu kalasi. Kunena zoona, PP ndiye kuzimata bwino; PS, ABS, PC, PC + ABS, Pe pulasitiki kuzimata chachiwiri, koma luso kuzimata ndi okhwima kwambiri, kukwaniritsa ovemolding olimba popanda movutikira; nylon PA ovemolding zovuta adzakhala wamkulu, koma m'zaka zaposachedwapa luso lapita patsogolo kwambiri.

2. Waukulu pulasitiki overmolding TPE kuuma osiyanasiyana: PP overmolding kuuma ndi 10-95A; PC, ABS overmolding ranges kuchokera 30-90A; PS overmolding ndi 20-95A; nayiloni PA overmolding ndi 40-80A; Kuchuluka kwa POM kumayambira 50-80A.

Zovuta ndi Zothetsera mu TPE Overmolding

1. Kuyika ndi Peeling: Kupititsa patsogolo kugwirizana kwa TPE, sinthani liwiro la jekeseni ndi kupanikizika, ndikuwonjezera kukula kwa chipata.

2. Kuwonongeka Kosauka: Sinthani zinthu za TPE kapena yambitsani njere ya nkhungu kuti isanyezike.

3. Whitening and Stickiness: Sinthani ndalama zowonjezera kuti muchepetse kutulutsa kwamafuta ang'onoang'ono a maselo.

4. Kusintha kwa Zida Zapulasitiki Zolimba: Sinthani kutentha kwa jekeseni, kuthamanga, ndi kupanikizika, kapena kulimbikitsani mawonekedwe a nkhungu.

Tsogolo: Yankho la Si-TPV ku Mavuto Odziwika Pakuchulukirachulukira kwa Chiwonetsero Chokhazikika Chokongola

Ndizofunikira kudziwa kuti tsogolo la kuchulukira likukula ndikulumikizana kwapamwamba ndi zida zogwira zofewa!

Buku la thermoplastic silicone-based elastomer lithandizira kuumba kofewa m'mafakitale momasuka komanso mosangalatsa.

SILIKE imabweretsa yankho losasunthika, vulcanizate thermoplastic Silicone-based elastomers(Short for Si-TPV), kudutsa malire azikhalidwe. Izi zimaphatikiza mawonekedwe olimba a ma elastomer a thermoplastic okhala ndi silikoni yosilira, zomwe zimapatsa kukhudza kofewa, kumva kosalala, komanso kukana kuwala kwa UV ndi mankhwala.Si-TPV elastomers amawonetsa kumamatira kwapadera pamagawo osiyanasiyana, kusungitsa kusinthika ngati zida wamba za TPE. Amachotsa ntchito zachiwiri, zomwe zimapangitsa kuti azithamanga mofulumira komanso kuchepetsa ndalama. Si-TPV imapereka mawonekedwe owoneka bwino ngati mphira wa silikoni kumagawo owumbidwa kwambiri. Kuphatikiza pa zinthu zake zochititsa chidwi, Si-TPV imakumbatira kukhazikika mwa kubwezeredwanso komanso kugwiritsidwanso ntchito m'njira zopangira zachikhalidwe. Izi zimakulitsa kuyanjana kwachilengedwe komanso kumathandizira kuti pakhale njira zokhazikika zopangira.

Ma elastomer a Si-TPV opanda pulasitiki ndi oyenera kukhudzana ndi khungu, kupereka mayankho m'mafakitale osiyanasiyana. Pakuchulukira kofewa pazida zamasewera, zida, ndi zogwirira zosiyanasiyana, Si-TPV imawonjezera 'kumverera' kwabwino kwa malonda anu, kukulitsa luso la mapangidwe ndi kuphatikiza chitetezo, kukongola, magwiridwe antchito, ndi ergonomics kwinaku mukutsatira machitidwe okonda zachilengedwe.

Ubwino wa Soft Overmolding ndi Si-TPV

1. Kukhudza Kwambiri ndi Kukhudza: Si-TPV imapereka mawonekedwe a silky kwa nthawi yayitali, omasuka pakhungu popanda masitepe owonjezera. Imakulitsa kwambiri zokumana nazo zogwira ndi kukhudza, makamaka pazogwira ndi zogwira.

2. Kuwonjezeka kwa Chitonthozo ndi Kumverera Kosangalatsa: Si-TPV imapereka malingaliro osakhala a tacky omwe amatsutsana ndi dothi, amachepetsa kutulutsa fumbi, komanso amachotsa kufunikira kwa plasticizers ndi mafuta ochepetsetsa. Simagwetsa mvula ndipo ilibe fungo.

3. Kukhazikika Kwabwino Kwambiri: Si-TPV imawonjezera kukanda kolimba komanso kukana kwa ma abrasion, kuonetsetsa kuti utoto utalikirapo, ngakhale utakhala ndi thukuta, mafuta, kuwala kwa UV, ndi mankhwala. Imasungabe kukongola, zomwe zimathandizira kuti zinthu zizikhala ndi moyo wautali.

4. Mayankho Osiyanasiyana Owonjezera: Si-TPV imadziphatika yokha ku mapulasitiki olimba, ndikupangitsa zosankha zapadera zowonjezereka. Imalumikizana mosavuta ndi PC, ABS, PC/ABS, TPU, PA6, ndi magawo ena a polar osafunikira zomatira, kuwonetsa luso lapadera lowumba.

Pamene tikuwona kusinthika kwa zinthu zochulukirapo, Si-TPV imadziwika ngati mphamvu yosinthira. Kukoma kwake kosafanana ndi kukhudza kofewa komanso kukhazikika kumapangitsa kukhala zinthu zamtsogolo. Onani zomwe zingatheke, yambitsani mapangidwe anu, ndikukhazikitsa miyezo yatsopano m'magawo osiyanasiyana ndi Si-TPV. Landirani chisinthiko pakuwonjezera kukhudza kofewa - tsogolo lili pano!
