I-PBT isifinyezo se-Polybutylene terephthalate. Ihlukaniswa ochungechungeni lwe-polyester. Yakhiwe nge-1.4-Butylene glycol ne-terephthalic acid (TPA) noma i-terephthalate (DMT). I-milky translucent to opaque, crystalline thermoplastic polyester resin eyenziwe ngenqubo yokuhlanganisa. Ihlangene ne-PET, ibizwa ngokuhlanganyela ngokuthi i-thermoplastic polyester, noma i-polyester egcwele.
Izici zePBT Plastics
1. Ukuguquguquka kwepulasitiki ye-PBT kuhle kakhulu futhi futhi imelana kakhulu nokuwa, futhi ukumelana kwayo okuqinile kunamandla uma kuqhathaniswa.
2. I-PBT ayivuthi njengamapulasitiki ajwayelekile. Ngaphezu kwalokho, umsebenzi wayo wokuzicisha kanye nezakhiwo zikagesi ziphakeme kakhulu kule pulasitiki ye-thermoplastic, ngakho intengo iyabiza kakhulu phakathi kwamapulasitiki.
3. Ukusebenza kokumuncwa kwamanzi kwe-PBT kuphansi kakhulu. Amapulasitiki avamile akhubazeka kalula emanzini anokushisa okuphezulu. I-PBT ayinayo le nkinga. Ingasetshenziswa isikhathi eside futhi igcine ukusebenza okuhle kakhulu.
4. Ingaphezulu le-PBT libushelelezi kakhulu futhi i-coefficient ye-friction incane, okwenza kube lula ukuyisebenzisa. Futhi kungenxa yokuthi i-coefficient yayo yokungqubuzana incane, ngakho ivamise ukusetshenziswa ezikhathini lapho ukulahleka kokungqubuzana kukhulu uma kuqhathaniswa.
5. Ipulasitiki ye-PBT inozinzo oluqine kakhulu inqobo nje uma isakhiwe, futhi igxile kakhulu ngokunemba kobukhulu, ngakho iyimpahla yepulasitiki yekhwalithi ephezulu kakhulu. Ngisho nakumakhemikhali esikhathi eside, ingakwazi ukugcina isimo sayo sokuqala kahle, ngaphandle kwezinye izinto ezifana nama-asidi aqinile nezisekelo eziqinile.
6. Amapulasitiki amaningi anekhwalithi eqinisiwe, kodwa izinto ze-PBT azinjalo. Izakhiwo zayo zokugeleza zinhle kakhulu, futhi izakhiwo zayo zokusebenza zizoba ngcono ngemuva kokubunjwa. Ngoba yamukela ubuchwepheshe be-polymer fusion, yenelisa ezinye izakhiwo ze-alloy ezidinga i-polymer.
Ukusetshenziswa okuyinhloko kwe-PBT
1. Ngenxa yezakhiwo zayo ezinhle ezingokomzimba namakhemikhali, i-PBT ivamise ukusetshenziswa njengezinto ezikhiphayo zokumbozwa kwesibili kwamafibre optical kukhebula yefiber optical yangaphandle.
2. Izicelo ze-elekthronikhi nezikagesi: izixhumi, izingxenye zokushintsha, izinto zikagesi zasendlini noma izesekeli (ukumelana nokushisa, ukuncipha komlilo, ukufakwa kukagesi, ukubumba okulula nokucubungula).
3. Izinkambu zokufaka izicelo zezingxenye ezizenzakalelayo: izingxenye zangaphakathi njengabakaki be-wiper, ama-valve esistimu yokulawula, njll.; izingxenye zikagesi nezikagesi njengamapayipi asontekile ekhoyili yokuthungela imoto kanye nezixhumi zikagesi ezihlobene.
4. Izinkambu zokufaka izicelo zomshini ojwayelekile: ikhava yekhompiyutha, isembozo sesibani semercury, isembozo sensimbi kagesi, izingxenye zomshini wokubhaka kanye nenani elikhulu lamagiya, amakhamera, izinkinobho, amagobolondo ewashi kagesi, ama-drill kagesi namanye amagobolondo ayimishini.
