Polybutylene terephthalate(PBT) ndi polyester yodzaza ndi semi-crystalline, thermoplastic saturated, nthawi zambiri yoyera ngati mkaka, granular solid pa kutentha kwa chipinda, yomwe imagwiritsidwa ntchito kwambiri popanga zinthu zophimba za thermoplastic secondary cable.
Kuphimba kwachiwiri kwa ulusi wa kuwala ndi njira yofunika kwambiri pakupanga ulusi wa kuwala. Mwachidule, kuwonjezera gawo loteteza ku chophimba chachikulu cha ulusi wa kuwala kapena gawo la buffer kungathandize kukonza luso la ulusi wa kuwala kuti upewe kupsinjika kwa nthawi yayitali komanso kwa radial ndikupangitsa kuti ulusi wa kuwala ugwire ntchito pambuyo pa kukonza. Chifukwa chakuti zinthu zophimbazo zili pafupi ndi ulusi wa kuwala, zimakhudza kwambiri magwiridwe antchito a ulusi wa kuwala, kotero zinthu zophimbazo zimafunika kukhala ndi coefficient yaying'ono yokulirapo, kristalo yayikulu pambuyo pa extrusion, kukhazikika kwa mankhwala ndi kutentha, makoma osalala amkati ndi akunja a chophimbacho, mphamvu inayake yolimba ndi modulus ya Young, ndipo imakhala ndi magwiridwe antchito abwino. Kuphimba kwa ulusi nthawi zambiri kumagawidwa m'magulu awiri: chophimba chomasuka ndi chophimba cholimba. Pakati pawo, zinthu zomasuka zomwe zimagwiritsidwa ntchito mu chophimba chomasuka ndi gawo lachiwiri lophimba lomwe limatulutsidwa mu malo omasuka akunja kwa ulusi woyamba wophimba.
PBT ndi nsalu yogwiritsidwa ntchito kwambiri yomasuka yokhala ndi mawonekedwe abwino komanso kukonza, imayamwa chinyezi chochepa komanso imakhala ndi mtengo wotsika. Imagwiritsidwa ntchito kwambiri muPBTkusintha, kujambula waya wa PBT, chivundikiro, kujambula filimu ndi zina. PBT ili ndi makhalidwe abwino a makina (monga kukana kugwedezeka, kukana kupindika, kukana kupanikizika kwa mbali), kukana kusungunuka bwino, kukana mafuta, kukana dzimbiri kwa mankhwala, ndi phala la ulusi, phala la chingwe ndi zigawo zina za chingwecho zimagwirizana bwino, ndipo zimakhala ndi magwiridwe antchito abwino kwambiri opangira utomoni, kuyamwa chinyezi pang'ono, komanso zotsika mtengo. Miyezo yake yayikulu yaukadaulo yogwirira ntchito ndi monga: kukhuthala kwamkati, mphamvu yokolola, kukhuthala ndi kupindika kwa elastic modulus, mphamvu yokhudza kugwedezeka (notch), coefficient yokulitsa mzere, kuyamwa kwa madzi, kukana hydrolysis ndi zina zotero.
Komabe, ndi kusintha kwa kapangidwe ka chingwe cha ulusi ndi malo ogwirira ntchito, zofunikira zambiri zikuperekedwa patsogolo pa fiber bushing. Makristalo apamwamba, kuchepa pang'ono, kuchuluka kochepa kwa kukulitsa mzere, kulimba kwambiri, mphamvu yayikulu yokakamiza, kukana mankhwala bwino, magwiridwe antchito abwino, ndi zipangizo zotsika mtengo ndi zolinga zomwe opanga chingwe cha kuwala amatsatira. Pakadali pano, pali zofooka pakugwiritsa ntchito ndi mtengo wa chubu cha beam chopangidwa ndi zinthu za PBT, ndipo mayiko akunja ayamba kugwiritsa ntchito zinthu za PBT alloy kuti alowe m'malo mwa zinthu zoyera za PBT, zomwe zakhala ndi zotsatira zabwino komanso udindo wabwino. Pakadali pano, makampani akuluakulu angapo a chingwe akunyumba akukonzekera mwachangu, makampani azinthu za chingwe akufunika luso lopitilira laukadaulo, kafukufuku ndi chitukuko cha zinthu zatsopano.
Zachidziwikire, mumakampani onse a PBT, kugwiritsa ntchito chingwe cha fiber optic kumangokhala gawo laling'ono chabe la msika wa PBT. Malinga ndi magwero amakampani, mumakampani onse a PBT, gawo lalikulu la msika limakhala makamaka m'magawo awiri a magalimoto ndi magetsi. Zolumikizira, zolumikizira ndi zinthu zina zopangidwa ndi zinthu zosinthidwa za PBT zimagwiritsidwa ntchito kwambiri m'magalimoto, zida zamagetsi ndi zamagetsi, zida zamakanika ndi zina, ndipo ngakhale PBT imagwiritsa ntchito m'munda wa nsalu, monga ma bristles a burashi ya mano amapangidwanso ndi PBT. Izi ndi zomwe PBT imagwiritsa ntchito m'magawo osiyanasiyana:
1. Minda yamagetsi ndi yamagetsi
Zipangizo za PBT zimagwiritsidwa ntchito kwambiri m'magawo amagetsi ndi zamagetsi, monga ma soketi amagetsi, mapulagi, ma soketi amagetsi ndi zida zina zamagetsi zapakhomo. Chifukwa chakuti zipangizo za PBT zili ndi mphamvu yabwino yotetezera kutentha komanso zimateteza kutentha kwambiri, ndizoyenera kwambiri chipolopolo, bulaketi, pepala lotetezera kutentha ndi zida zina zamagetsi ndi zamagetsi. Kuphatikiza apo, zipangizo za PBT zingagwiritsidwenso ntchito popanga chophimba chakumbuyo cha LCD, chipolopolo cha TV ndi zina zotero.
2. Malo ochitira magalimoto
Zipangizo za PBT zimagwiritsidwanso ntchito kwambiri m'magalimoto. Chifukwa cha ubwino wake wa kutentha kwambiri, dzimbiri komanso kusawonongeka, zipangizo za PBT zimagwiritsidwa ntchito kwambiri popanga zida zamagalimoto, monga intake manifold, oil pump housing, sensor housing, brake system components, etc. Kuphatikiza apo, zipangizo za PBT zingagwiritsidwenso ntchito poika mitu ya mipando yamagalimoto, njira zosinthira mipando, ndi zina zotero.
3. Makampani opanga makina
Mu makampani opanga makina, zipangizo za PBT nthawi zambiri zimagwiritsidwa ntchito popanga zida zogwirira ntchito, ma switch, mabatani, ndi zina zotero. Zipangizo za PBT zili ndi mphamvu zabwino kwambiri zamakaniko komanso kukana kuwonongeka, zimatha kupirira mphamvu zosiyanasiyana zamakaniko, komanso zimakhala ndi kukana dzimbiri kwa mankhwala, zoyenera magawo osiyanasiyana m'makampani opanga makina.
4. Makampani opanga zida zamankhwala
Zipangizo za PBT zimakhala ndi mphamvu yolimbana ndi kutentha kwambiri komanso zimakhala ndi mphamvu yolimba ya mankhwala, zomwe ndizoyenera kwambiri popanga zipangizo zachipatala. Mwachitsanzo, zipangizo za PBT zingagwiritsidwe ntchito popanga zida zachipatala, mapaipi, zolumikizira, ndi zina zotero. Kuphatikiza apo, zipangizo za PBT zingagwiritsidwenso ntchito popanga ma syringe azachipatala, ma infusion sets ndi zida zosiyanasiyana zochiritsira.
5. Kulankhulana kwa kuwala
Pankhani yolumikizirana ndi kuwala, PBT imagwiritsidwa ntchito kwambiri popanga zingwe za kuwala ngati chinthu chofala chomasuka. Kuphatikiza apo, zipangizo za PBT zimagwiritsidwa ntchito kwambiri mu zipangizo zamagetsi. Chifukwa cha mawonekedwe ake abwino komanso kukana kutentha kwambiri, zipangizo za PBT zimagwiritsidwa ntchito popanga zolumikizira za ulusi wa kuwala, mafelemu ogawa ulusi wa kuwala, ndi zina zotero. Kuphatikiza apo, zipangizo za PBT zingagwiritsidwenso ntchito popanga magalasi, magalasi, mawindo ndi zida zina zamagetsi.
Kuchokera ku malingaliro a makampani onse, m'zaka zaposachedwa, mabizinesi oyenerera adzipereka pakupanga njira zosiyanasiyana zogwiritsira ntchito ukadaulo watsopano ndi zinthu zatsopano, ndipo PBT yakula bwino kwambiri, magwiridwe antchito komanso kusiyanasiyana. Mphamvu yolimba ya utomoni wa PBT, mphamvu yopindika, ndi modulus yopindika ndizochepa, sizingagwiritsidwe ntchito kwambiri m'mafakitale, kotero pazosowa zamakampani, makampaniwa amasinthidwa kuti akonze magwiridwe antchito a PBT. Mwachitsanzo, utomoni wagalasi umawonjezeredwa ku PBT - utomoni wagalasi uli ndi ubwino wogwiritsidwa ntchito mwamphamvu, njira yosavuta yodzaza komanso mtengo wotsika. Powonjezera utomoni wagalasi ku PBT, zabwino zoyambirira za utomoni wa PBT zimayikidwa, ndipo mphamvu yolimba, mphamvu yopindika, ndi mphamvu yogwira ntchito ya zinthu za PBT zimawonjezeka kwambiri.
Pakadali pano, njira zazikulu zomwe zimagwiritsidwa ntchito kunyumba ndi kunja ndi kusintha kwa copolymerization, kusintha kwa zinthu zosapangidwa ndi zinthu zachilengedwe, ukadaulo wa nanocomposite, kusintha kosakaniza, ndi zina zotero, kuti PBT igwire bwino ntchito. Kusintha kwa zinthu za PBT kumayang'ana kwambiri mbali za mphamvu yayikulu, kuletsa moto kwambiri, kuwononga mpweya pang'ono, mvula yochepa komanso dielectric yochepa.
Kawirikawiri, ponena za makampani onse a PBT, kufunika kwa ntchito m'magawo osiyanasiyana kukadali kwakukulu, ndipo kusintha kosiyanasiyana malinga ndi kufunika kwa msika ndizomwe zolinga zodziwika bwino za kafukufuku ndi chitukuko cha makampani a PBT.
