Kodi PBT ndi chiyani ndipo chifukwa chiyani imagwiritsidwa ntchito kwambiri?

Polybutylene Terephthalate (PBT) ndi thermoplastic yopangidwa bwino kwambiri yopangidwa kuchokera ku butylene glycol ndi terephthalic acid, yokhala ndi makhalidwe ofanana ndi Polyethylene Terephthalate (PET). Monga membala wa banja la polyester, PBT imagwiritsidwa ntchito kwambiri mu magalimoto, zamagetsi, komanso zida zolondola chifukwa cha mphamvu zake zamakanika, kukhazikika kwabwino kwa kutentha, kutchinjiriza magetsi, kukana mankhwala, ndi chinyezi. Ubwino uwu umapangitsa kuti ikhale chinthu chodziwika bwino cholumikizira, zophimba, ndi zokongoletsera zamkati.

Nchifukwa chiyani mavuto a pamwamba pa PBT akukhala nkhawa yayikulu pa ntchito zamafakitale apamwamba?

Pamene mafakitale monga magalimoto, zamagetsi, ndi uinjiniya wolondola akukweza kwambiri mawonekedwe ndi kulimba kwa zinthu, Polybutylene Terephthalate (PBT)—pulasitiki yogwiritsidwa ntchito kwambiri paukadaulo—ikukumana ndi kupsinjika kwakukulu kuti ipereke mawonekedwe abwino kwambiri.

Ngakhale kuti PBT ndi yolimba kwambiri pamakina komanso kutentha, imatha kukhudzidwa ndi zolakwika pamwamba pa makinawo—makamaka ikakumana ndi kutentha, kudulidwa, kapena chinyezi. Zolakwika zimenezi zimakhudza mwachindunji osati mawonekedwe a chinthucho okha komanso kudalirika kwa ntchito yake.

Malinga ndi deta yamakampani, zolakwika zomwe zimapezeka kwambiri pazinthu za PBT ndi izi:

• Mizere Yasiliva/Zizindikiro Zamadzi: Zilema zomwe zimawoneka ngati mawonekedwe a radial pamwamba pa chinthucho chifukwa cha chinyezi, mpweya, kapena zinthu zopangidwa ndi kaboni motsatira njira yoyendera

• Zizindikiro za Mpweya: Kutsika kwa pamwamba kapena thovu lopangidwa pamene mpweya womwe uli mu kusungunuka sunatuluke kwathunthu

• Zizindikiro za Kuyenda: Mawonekedwe a pamwamba omwe amachokera ku kuyenda kosalingana kwa zinthu

• Zotsatira za Peel ya Lalanje: Kapangidwe ka pamwamba kamafanana ndi peel ya lalanje

• Kukanda Pamwamba: Kuwonongeka kwa pamwamba komwe kumachitika chifukwa cha kukangana panthawi yogwiritsa ntchito

Zolakwika izi sizimangokhudza kukongola kwa zinthu zokha komanso zingayambitse mavuto pakugwira ntchito. Mavuto okanda pamwamba amapezeka kwambiri m'magalimoto apamwamba komanso m'magetsi, ndipo ziwerengero zikusonyeza kuti oposa 65% ya ogula amaona kuti kukana kukanda ndi chizindikiro chofunikira poyesa ubwino wa zinthu.

Kodi Opanga PBT Angathetse Bwanji Mavuto Okhudza Ziphuphu Zapamwamba?Kupanga Zinthu Zatsopano!

Ukadaulo Wosintha Zinthu Zosiyanasiyana:Zipangizo za BASF za Ultradur® Advanced series PBT zomwe zatulutsidwa kumene zimagwiritsa ntchito ukadaulo watsopano wosintha zinthu zambiri, zomwe zimawonjezera kuuma kwa pamwamba ndi kukana kukanda poika magawo enaake a zigawo za PMMA mu matrix ya PBT. Deta yoyesera ikuwonetsa kuti zipangizozi zimatha kuuma pensulo ndi 1H-2H, kuposa 30% kuposa PBT yachikhalidwe.

Ukadaulo Wowonjezera Nano:Covestro yapanga njira zopangira PBT zowonjezeredwa ndi nano-silica zomwe zimawonjezera kuuma kwa pamwamba kufika pamlingo wa 1HB pomwe zimasunga mawonekedwe owonekera a zinthu, ndikuwonjezera kukana kukanda ndi pafupifupi 40%. Ukadaulo uwu ndi woyenera makamaka mkati mwa magalimoto ndi nyumba zamagetsi zapamwamba zomwe zimafunikira mawonekedwe okhwima.

Ukadaulo Wowonjezera Wochokera ku Silicone:Pofuna kuthana ndi mavuto ofunikira awa, SILIKE, katswiri wotsogola muukadaulo wowonjezera wa polima, wapanga mndandanda wa njira zowonjezera zochokera ku siloxane zomwe zapangidwira makamaka PBT ndi ma thermoplastic ena. Zowonjezera zothandizazi zimayang'ana zomwe zimayambitsa zolakwika pamwamba ndikuwongolera magwiridwe antchito opangira komanso kulimba kwa zinthu.

Mayankho Owonjezera Ochokera ku Silike's Silicone Othandizira Kukweza PBT Pamwamba

1. Chowonjezera cha pulasitiki LYSI-408: Chowonjezera cha Siloxane Cholemera Kwambiri cha Ma Molecular cha Mayankho a PBT Surface Defects

Silicone Masterbatch LYSI-408 ndi mankhwala opangidwa ndi pelletized okhala ndi 30% ultra high molecular weight siloxane polymer yomwe imafalikira mu polyester (PET). Imagwiritsidwa ntchito kwambiri ngati chowonjezera chogwira ntchito bwino cha PET, PBT, ndi resin system yogwirizana kuti ikonze bwino momwe imagwirira ntchito komanso ubwino wake pamwamba.

Ubwino waukulu wogwiritsa ntchito LYSI-408 yowonjezera pa pulasitiki ya PBT:

• Imathandizira kuyenda bwino kwa utomoni, kutulutsa nkhungu, komanso kumalizitsa pamwamba

• Amachepetsa mphamvu ya extruder ndi kukangana, kuchepetsa kupangika kwa zokwawa

• Kuyika kwachizolowezi: 0.5–2 wt%, kokonzedwa bwino kuti zigwire bwino ntchito/ndalama ziyende bwino

2. Silicone Sera SILIMER 5140: Silicone Yowonjezeredwa ndi Polyester mu Thermoplastics ya Uinjiniya

SILIMER 5140 ndi chowonjezera cha silicone chosinthidwa ndi polyester chomwe chili ndi kutentha kwabwino kwambiri. Chimagwiritsidwa ntchito mu zinthu za thermoplastic monga PE, PP, PVC, PMMA, PC, PBT, PA, PC/ABS, ndi zina zotero. Zingathe kusintha mawonekedwe a pamwamba pa zinthu zomwe sizimakanda komanso sizimawonongeka, kusintha kukhuthala ndi kutulutsa nkhungu pa njira yopangira zinthu kuti zinthuzo zikhale bwino.

Ubwino waukulu wa Silicone Wax SILIMER 5140 pa pulasitiki yaukadaulo ya PBT:

• Amapereka kukhazikika kwa kutentha, kukana kukanda ndi kutha, komanso kufewetsa pamwamba

• Zimathandiza kuti zinthu zizitha kuumba bwino komanso zimawonjezera nthawi ya moyo wa zinthuzo

Mukufuna Kuchotsa Zolakwika Pamwamba, Kukweza Kukongola kwa Zinthu, ndi Kukweza Magwiridwe Abwino a Zinthu za PBT?

Kwa makampani opanga zinthu zamagetsi ndi opanga zinthu zophatikizana m'mafakitale opanga magalimoto, zamagetsi, ndi mapulasitiki olondola, kugwiritsa ntchito zowonjezera zapulasitiki zochokera ku siloxane ndi njira yodziwika bwino yothanirana ndi mavuto opanga ndikuwonjezera ubwino wa pamwamba ndi kukana kukanda mu PBT. Njirayi imathandiza kukwaniritsa zomwe msika ukuyembekezeredwa.

SILIKE ndi kampani yotsogola yopereka zowonjezera zapulasitiki zosinthidwa za PBT ndi mitundu yosiyanasiyana ya thermoplastics, yopereka njira zatsopano zowonjezerera magwiridwe antchito ndi magwiridwe antchito a zipangizo zapulasitiki. Ndi zaka zoposa 20 zaukadaulo wamakampani, timadziwa bwino kupanga ndi kupanga zowonjezera zapamwamba zomwe zimakweza ubwino wa pamwamba, komanso kukonza zinthu zapulasitiki.

Lumikizanani ndi SILIKE kuti mudziwe momwe njira zathu zowonjezera za PBT zingakuthandizireni kukonza bwino mtundu wa malonda ndi magwiridwe antchito ake—mothandizidwa ndi ukatswiri wathu waukadaulo komanso chithandizo cha mapulogalamu okonzedwa bwino.
