PBT yog lub npe luv ntawm Polybutylene terephthalate. Nws yog cais nyob rau hauv polyester series. Nws yog tsim los ntawm 1.4-Butylene glycol thiab terephthalic acid (TPA) lossis terephthalate (DMT). Nws yog ib qho mis nyuj translucent rau opaque, crystalline thermoplastic polyester resin ua los ntawm cov txheej txheem compounding. Ua ke nrog PET, nws tau sau npe hu ua thermoplastic polyester, los yog saturated polyester.
Cov yam ntxwv ntawm PBT Plastics
1. Kev hloov pauv ntawm PBT yas yog qhov zoo heev thiab nws kuj tseem tiv taus kev ntog, thiab nws cov nkig kuj tseem muaj zog.
2. PBT tsis yog nplaim taws zoo li cov yas zoo tib yam. Tsis tas li ntawd, nws tus kheej-extinguishing muaj nuj nqi thiab hluav taws xob cov khoom yog kuj siab nyob rau hauv no thermoplastic yas, yog li tus nqi kuj kim ntawm plastics.
3. Kev nqus dej ua haujlwm ntawm PBT tsawg heev. Ordinary plastics tau yooj yim deformed hauv dej nrog qhov kub siab dua. PBT tsis muaj qhov teeb meem no. Nws tuaj yeem siv tau ntev thiab tuav tau zoo heev.
4. Qhov saum npoo ntawm PBT yog du heev thiab kev sib txhuam coefficient me me, uas ua rau nws yooj yim dua rau kev siv. Nws kuj yog vim nws qhov kev sib txhuam coefficient me me, yog li nws feem ntau siv rau qee lub sijhawm uas qhov kev sib txhuam poob loj heev.
5. PBT yas muaj qhov ruaj khov heev ntev npaum li nws tau tsim, thiab nws yog qhov tshwj xeeb tshaj plaws ntawm qhov raug, yog li nws yog cov khoom siv yas zoo heev. Txawm tias nyob rau hauv cov tshuaj mus sij hawm ntev, nws muaj peev xwm tswj tau nws cov thawj lub xeev zoo, tshwj tsis yog rau qee yam khoom xws li acids muaj zog thiab muaj zog hauv paus.
6. Ntau cov yas yog cov khoom siv ntxiv zoo, tab sis cov ntaub ntawv PBT tsis yog. Nws cov khoom ntws zoo heev, thiab nws cov khoom ua haujlwm yuav zoo dua tom qab molding. Vim tias nws siv cov thev naus laus zis polymer fusion, nws txaus siab rau qee cov khoom siv hlau uas xav tau polymer.
Kev siv tseem ceeb ntawm PBT
1. Vim nws lub cev zoo thiab cov khoom siv tshuaj lom neeg, PBT feem ntau yog siv los ua cov khoom siv extrusion rau cov txheej thib ob ntawm cov khoom siv kho qhov muag nyob rau sab nraum zoov optical fibers.
2. Kev siv hluav taws xob thiab hluav taws xob: cov khoom sib txuas, hloov qhov chaw, cov khoom siv hauv tsev lossis cov khoom siv (kub tsis kam, nplaim hluav taws xob, hluav taws xob rwb thaiv tsev, yooj yim molding thiab ua haujlwm).
3. Daim ntawv thov teb ntawm nws pib qhov chaw: sab hauv xws li wiper brackets, tswj system li qub, thiab lwm yam .; hluav taws xob thiab hluav taws xob qhov chaw xws li tsheb ignition coil twisted kav thiab lwm yam hluav taws xob connectors.
4. General tshuab accessories daim ntawv thov teb: lub computer cover, mercury teeb cover, hluav taws xob hlau cover, ci tshuab qhov chaw thiab ib tug loj tus naj npawb ntawm gears, cams, nyees khawm, hluav taws xob saib plhaub, hluav taws xob xyaum thiab lwm yam mechanical shells.
