Polybutylene terephthalate (PBT). Tam sim no, ntau dua 80% ntawm lub ntiaj teb PBT raug hloov kho tom qab siv, PBT hloov kho engineering plastics nrog nws cov yam ntxwv zoo ntawm lub cev, tshuab thiab hluav taws xob hauv hluav taws xob thiab hluav taws xob tau siv dav.
Hloov kho cov khoom siv PBT
1. Cov khoom siv zoo heev, tshwj xeeb tshaj yog siab rigidity thiab hardness;
2. Zoo tiv thaiv tshav kub, thermal deformation kub tuaj yeem ncav cuag 180 ℃ lossis siab dua;
3. Zoo nto gloss kev ua tau zoo, tshwj xeeb tshaj yog tsim rau cov khoom siv hluav taws xob thiab hluav taws xob tsis pub dawb;
4. Ceev ceev crystallization, zoo fluidity, zoo molding;
5. Zoo thermal stability, tshwj xeeb tshaj yog tsawg thermal expansion tus nqi thiab loj shrinkage tus nqi;
6. Cov tshuaj tiv thaiv zoo, cov kuab tshuaj, huab cua tsis kam, siab dielectric zog, kev ua haujlwm zoo hluav taws xob;
7. Tsawg hygroscopicity, me ntsis cuam tshuam rau hluav taws xob thiab seem stability.

1. Lub teeb txuag hluav taws xob
PBT yog dav siv nyob rau hauv lub zog txuag teeb kev lag luam. Ntau tshaj 90% ntawm cov yas txuag hluav taws xob lub taub hau yog ua los ntawm cov khoom siv PBT. Cov khoom lag luam yuav tsum muaj xim zoo, xim pob tshab, xim xaiv, UL94 nplaim retardant V0, zoo hluav taws xob rwb thaiv tsev, zoo mechanical zog, yooj yim rau txheej txheem.
2. Lub connector
Cov khoom siv txuas feem ntau yog iav fiber ntau ntxiv PBT, kev ua haujlwm yuav tsum tau ua rau UL 94 V0 nplaim hluav taws, zoo zog thiab toughness, tsis tshua muaj noo noo nqus, hluav taws xob thiab qhov ntev stability me ntsis, zoo nto, zoo luster, tsis pom tseeb ntab fiber ntau.
3. Lub tshuab cua txias kiv cua
Cov khoom lag luam yuav tsum muaj peev xwm tiv taus qhov kub siab ntawm 130 ℃ rau lub sijhawm ntev, kev ua haujlwm zoo gloss thiab kev ua haujlwm siab nplaim taws.
