Nkhani - Si-TPV 3220-85A Ikhoza Kukweza Kwambiri Kumva ndi Kukonza Manja ndi Mphamvu Yapamwamba Kwambiri ya Matte ya Zinthu Zosindikizira za TPU 3D

Zipangizo zosindikizira za TPU monofilament 3D, Matte Effect For Tpu 3D printing, Matte Tpu Monofilament Modifier, Long-Term Silky-Friendly Skin-Comfort Soft Touch Zipangizo, Silky And Skin-Friendly Touch Zipangizo 1

M'magawo a zamagetsi, zovala zamafashoni, mkati mwa magalimoto opangidwa mwamakonda komanso zothandizira zachipatala zapamwamba, kusindikiza kwa 3D kukukwaniritsa kusintha kwa mafakitale kuchokera pakupanga zitsanzo mpaka kupanga zinthu zomaliza mwachindunji, zomwe ndi njira yayikulu yopititsira patsogolo makampani opanga ma elastomer osindikizira a 3D. Kufunikira kwa msika kwa zinthu zosindikizidwa kwadutsa zofunikira zoyambira za "kusindikiza ndi kupanga bwino", kusamukira kukufunafuna zinthu ziwiri zomwe zimakupangitsani kumva bwino komanso kugwira ntchito bwino m'mafakitale — ndikofunikira kuti khungu likhale lofewa komanso looneka bwino, pamene mukukwaniritsa njira ndi miyezo yogwirira ntchito yosindikiza bwino komanso kugwiritsa ntchito nthawi yayitali, zomwe zimapangitsa kuti pakhale kufunikira kwakukulu kwa ntchito zosindikizira zapamwamba za 3D. Popeza ndi njira yogwiritsidwa ntchito kwambiri posindikiza za elastomer 3D, ulusi wachikhalidwe wa thermoplastic polyurethane (TPU) umayang'anizana ndi zovuta zaukadaulo zosagonjetseka pakulinganiza kusinthasintha kwa kusindikiza ndi luso la zinthu zomaliza. Si-TPV (thermoplastic vulcanizate silicone) Innovative Elastomer, chinthu chapamwamba cha ulusi chopangidwa mwapadera cha Fused Deposition Modeling (FDM), chimapereka yankho labwino kwambiri kudzera mu luso la zinthu la molekyulu, lomwe limakhala ngati njira yosinthira zinthu za elastomer zosindikizira zapamwamba za 3D.

Zofooka Zaukadaulo Zachikhalidwe za TPU Elastomers mu Mapulogalamu Osindikizira a 3D

Potengera kulimba kwake kwabwino, kulimba mtima kwake komanso kukana kutopa, TPU yakhala chisankho chachikulu cha ma elastomer osindikizira a 3D apakatikati mpaka otsika. Komabe, chifukwa cha makhalidwe ake enieni, zolakwika zaukadaulo zomwe imawonetsa pazochitika zapamwamba zimaletsa mwachindunji kusintha kwa khalidwe la malonda ndi magwiridwe antchito opangira:

Kusiyana kwachilengedwe pakati pa kuuma kwa kukhudza ndi chitonthozo chogwiritsa ntchito: Kuti zitsimikizire kuti zinthu zomangira pakati pa zigawo ndi zolimba pakasindikiza, ulusi wa TPU wachikhalidwe uyenera kukhala wolimba kwambiri, zomwe zimapangitsa kuti zinthu zomalizidwa zikhale zolimba komanso zosasinthasintha mokwanira. Kukhudzana ndi khungu kwa nthawi yayitali kungayambitse kupanikizika, zomwe zimapangitsa kuti zikhale zosatheka kukwaniritsa zofunikira zolimba zogwirira zovala, zothandizira zachipatala, zogwirira zapadera ndi zinthu zina.

Zofooka za kapangidwe ka pamwamba ndi ndalama zomwe zimagwiritsidwa ntchito pokonza zinthu: Zigawo zosindikizidwa za TPU nthawi zambiri zimakhala ndi mawonekedwe oonekera bwino pamwamba, okhala ndi pulasitiki yowala kapena yomata, yopanda mawonekedwe apamwamba powona komanso kukhudza. Kuti zinthu ziwoneke bwino zimafunika njira zokonzera zinthu pambuyo pake monga kupopera ndi kupukuta, zomwe sizimangowonjezera nthawi yopangira, komanso zimabweretsa chiopsezo cha kuwonongeka ndi kuchotsedwa kwa utoto, pomwe zimawonjezera ndalama zosamalira chilengedwe.

Mavuto ambiri aukadaulo pakutha kusindikiza: Yoletsedwa ndi mphamvu yosungunuka ndi mphamvu ya rheological, TPU imakonda kusonkhanitsa zinthu pa nozzle orifice panthawi yosindikiza, zomwe zimayambitsa mavuto monga kusokoneza zingwe ndi kusindikiza, zomwe zimachepetsa mwachindunji kupambana kwa kusindikiza komanso kutha kwa pamwamba. Zofooka za melt flow index (MFI) yake zimalepheretsanso kukwera kwa liwiro losindikiza, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa kufunikira kwakukulu kwa kupanga kwapamwamba.

Si-TPV Innovative Elastomer:Yankho Lalikulu la Kusindikiza Kwapamwamba kwa 3D

Si-TPV si njira yosavuta yosinthira TPU, koma kudzera muukadaulo wolumikizirana wa dynamic vulcanization, tinthu tating'onoting'ono ta rabara la silicone tokhala ndi vulcanized tokwana 1-3μm timafalikira mofanana mu utomoni wa thermoplastic kuti tipange "kapangidwe ka chilumba" chapadera - utomoni wa thermoplastic umagwira ntchito ngati gawo lopitilira kuonetsetsa kuti zinthu zikuyenda bwino, ndipo rabara la silicone pamene gawo lofalikira limapereka chinthucho ndi magwiridwe antchito abwino kwambiri a zinthu zopangidwa ndi silicon. Imazindikira kuphatikiza kwa ubwino wa mphira wa silicone komanso kusavuta kwa pulasitiki ya thermoplastic pamlingo wa mamolekyulu, ndikupanga njira yothetsera mavuto a TPU, yokhala ndi zabwino zitatu zazikulu:

Kukhudza ngati khungu ndi kuuma kolamulirika: Si-TPV imatha kusintha kuuma kwa Shore, ndikukhalabe ndi mphamvu zabwino kwambiri pamakina omwe ali ndi kuuma kochepa (monga Shore A65), ndikuzindikira "kuuma kofewa". Sikuti imangopatsa zinthu zosindikizidwa kukhudza kofewa komanso kosalala ngati khungu, komanso imapereka chithandizo choyenera komanso kulimba, zomwe zimagwirizana bwino ndi ntchito zapamwamba kwambiri pokhudzana ndi khungu. Imathetsa mkangano pakati pa kuuma ndi chitonthozo cha TPU kuchokera kuzinthu zomwezo, ndipo imatha kukhala ndi chidziwitso chothandiza pakhungu kwa nthawi yayitali popanda zovuta pambuyo pokonza.

Njira yosindikizira yosalala komanso yogwira ntchito bwino popanga zinthu: Kapangidwe ka Si-TPV ka rheological kapangidwa mwanjira yolunjika, yokhala ndi mafuta osungunuka bwino kwambiri, omwe amatha kuchepetsa kwambiri kusonkhana kwa zinthu ndi kulumikiza pa nozzle orifice, kuonetsetsa kuti kusindikiza kosalekeza kwa nthawi yayitali kumakhala kokhazikika. Chizindikiro chake chapamwamba cha kusungunuka chimapangitsa kuti zinthuzo zikhale ndi kusinthasintha kwabwino pa kutentha kosindikiza, zomwe zimapangitsa kuti liwiro losindikiza liwonjezeke bwino poganizira kuti limapanga molondola, zomwe zimapangitsa kuti kupanga bwino komanso kukolola bwino kwa zinthu, komanso kusinthasintha kufunikira kwa mafakitale osindikiza a FDM 3D.

Kapangidwe kake ka matte komanso kukana kwa nthawi yayitali komanso kukana nyengo: Podalira mphamvu zake zapadera za pamwamba ndi kapangidwe kake kakang'ono, zida zosindikizidwa za Si-TPV zimatha kukhala ndi mawonekedwe ofanana komanso osalala, ndikuchotsa kwathunthu kumverera kwa pulasitiki ndi kumamatira kwa ma elastomer achikhalidwe, ndikukwaniritsa mawonekedwe apamwamba a kuwona ndi kukhudza pang'onopang'ono. Nthawi yomweyo, zinthuzo zilibe mapulasitiki kapena mafuta ofewetsa, kupewa mavuto a mvula, komanso zimakhala ndi mawonekedwe otsika a fumbi, kukana banga ndi kukana ukalamba wa UV, kusunga mawonekedwe okongola pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali ndikuchepetsa kwambiri mtengo wokonzanso pambuyo pake wazinthu.

Ndi jini yolumikizirana ya silicone rabara ndi thermoplastic pulasitiki, Si-TPV Innovative Elastomer imakwaniritsa zonse ziwirizofunikira kwambiri pa luso la zinthu zomalizidwandizofunikira pakupanga mafakitale zovutaza kusindikiza kwapamwamba kwa 3D, kukhala chinthu chofunikira kwambiri chomwe chikuyendetsa kukweza kwa ma elastomer osindikiza a 3D kuchokera ku "kuzindikira magwiridwe antchito" kupita ku "kupanga zokumana nazo zapamwamba". Tikuyitanitsa ogwira nawo ntchito mumakampani kuti afufuze pamodzi mwayi wogwiritsa ntchito Si-TPV m'mapulojekiti apamwamba osinthira kusindikiza kwa 3D, ndi luso lazinthu ngati maziko, zomwe zimapangitsa kuti luso la kusindikiza kwa 3D lipitirire mawonekedwe ake ndikufikira pamlingo wapamwamba kwambiri.
