High kub nylon hais txog cov khoom siv nylon uas tuaj yeem siv rau hauv ib puag ncig siab dua 150 ℃ rau lub sijhawm ntev. Lub melting point feem ntau yog 290 ℃ ~ 320 ℃, thiab thermal deformation kub ntawm iav fiber ntau hloov yog ntau tshaj 290 ℃. Nws kuj tseem tswj hwm kev ua haujlwm zoo heev ntawm qhov kub thiab txias thiab cov av noo siab.
Tam sim no, mature muaj kub nylon ntau yam yog PA46, PA6T, PA9T thiab PA10T
Vim nws cov khoom siv kho tshuab zoo, qhov kub nylon nylon yog dav siv hauv tshuab, hluav taws xob thiab kev lag luam
Cov khoom siv hluav taws xob thiab hluav taws xob ua haujlwm siab muaj cov khoom zoo heev, txhawm rau ua kom tau raws li cov kev xav tau ntawm kev siv hluav taws xob thiab hluav taws xob, cov khoom siv ntxiv muaj cov khoom nram qab no:
1. Tshaj 270 ℃ thermal deformation kub
2. Zoo heev dimension stability
3. Lub zog siab, siab modulus, siab cuam tshuam lub zog
4. Siab zog, siab modulus, siab cuam tshuam lub zog shrinkage
5. Kub kub thiab solder kuj
6. Cov rwb thaiv tsev hluav taws xob zoo heev
7. Mechanical kev lag luam cov ntaub ntawv ua tau zoo muaj cov khoom zoo heev. Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm cov khoom siv hauv kev lag luam, cov khoom siv ntxiv muaj cov khoom nram qab no:
8. Kub kub tsis kam, tshaj 270 ℃ thermal deformation kub
9. Tshuaj tiv thaiv
10. Siab zog, siab modulus, anti qaug zog
11. Kev ruaj ntseg zoo heev
12. Cov cua kub zoo heev thiab dej tsis kam
13. Cov roj ua haujlwm zoo heev
