PBT ke khutsufatso ea Polybutylene terephthalate. E arotsoe ka lihlopha tsa polyester. E entsoe ka 1.4-Butylene glycol le terephthalic acid (TPA) kapa terephthalate (DMT). Ke milky translucent ho opaque, crystalline thermoplastic polyester resin e entsoeng ka mokhoa oa ho kopanya. Hammoho le PET, ka kakaretso e bitsoa thermoplastic polyester, kapa polyester e tletseng.
Likarolo tsa PBT Plastics
1. Ho feto-fetoha ha polasetiki ea PBT ho molemo haholo hape ho hanyetsana haholo le ho oa, 'me ho hanyetsa ha eona ho brittle ho batla ho le matla.
2. PBT ha e chese joaloka polasetiki e tloaelehileng. Ho phaella moo, ts'ebetso ea eona ea ho itima-mola le thepa ea motlakase e batla e phahame ka polasetiki ena ea thermoplastic, kahoo theko e batla e le theko e boima har'a li-plastiki.
3. Ts'ebetso ea ho monya metsi ea PBT e tlase haholo. Li-plastiki tse tloaelehileng li holofala habonolo metsing a nang le mocheso o phahameng. PBT ha e na bothata bona. E ka sebelisoa nako e telele mme ea boloka ts'ebetso e ntle haholo.
4. Sebaka sa PBT se boreleli haholo 'me coefficient ea friction e nyenyane, e leng se etsang hore ho be bonolo ho e sebelisa. Hape ke hobane coefficient ea eona ea likhohlano e nyane, kahoo hangata e sebelisoa maemong ao tahlehelo ea likhohlano e batlang e le kholo.
5. Plastiki ea PBT e na le botsitso bo matla haholo ha feela e ntse e thehoa, 'me e totobetse haholoanyane ka ho nepahala ha dimensional, kahoo ke thepa ea polasetiki ea boleng bo phahameng haholo. Esita le lik'hemik'hale tsa nako e telele, e ka boloka boemo ba eona ba pele hantle, ntle le lintho tse ling tse kang li-acids tse matla le metheo e matla.
6. Li-plastiki tse ngata ke boleng bo matlafalitsoeng, empa lisebelisoa tsa PBT ha li joalo. Thepa ea eona ea ho phalla e ntle haholo, 'me thepa ea eona ea ho sebetsa e tla ba molemo ka mor'a ho bōptjoa. Hobane e sebelisa theknoloji ea polymer fusion, e khotsofatsa lisebelisoa tse ling tsa alloy tse hlokang polymer.
Tšebeliso ea mantlha ea PBT
1. Ka lebaka la thepa ea eona e ntle ea 'mele le ea lik'hemik'hale, hangata PBT e sebelisoa e le lisebelisoa tsa extrusion bakeng sa ho roala ha bobeli ba fiber optical ka ntle ho optical fiber cable.
2. Lisebelisoa tsa elektronike le tsa motlakase: li-connectors, li-switches, lisebelisoa tsa ntlo kapa lisebelisoa (ho hanyetsa mocheso, ho thibela lelakabe, ho kenya motlakase, ho bōptjoa habonolo le ho sebetsa).
3. Libaka tsa kopo ea likarolo tsa likoloi: likarolo tse ka hare tse kang li-wiper brackets, li-valve tsa tsamaiso ea tsamaiso, joalo-joalo; likarolo tsa elektroniki le tsa motlakase joalo ka liphaephe tse sothehileng tsa coil tsa koloi le likhokahanyo tse amanang le motlakase.
4. Likarolo tsa kopo ea lisebelisoa tsa mochini o akaretsang: sekoaelo sa komporo, sekoaelo sa lebone la mercury, sekoaelo sa tšepe ea motlakase, likarolo tsa mochini oa ho baka le palo e kholo ea likere, lik'hamera, likonopo, likhetla tsa ho shebella tsa elektroniki, li-drill tsa motlakase le likhetla tse ling tsa mochini.
