UHMWPE Fiber Ntau Txheej Txheem Whitepaper (2024 Revised tsab)

Mar 07, 2025 Tso lus

 

Tsis zoo siv


Cov Whitepaper elaborates ntawm txoj kev lag luam tsim qauv ntawmUltra-siab molecular hnyav polyethylene (UHMWPE) Fiber,Npog 12 tus txheej txheem cej mem ntawm cov ntsiab lus los ntawm cov khoom siv raw rau tom qab kev kho mob. Nws qhia tau qhov tseem ceeb heev cuam tshuam nrog fiber ntau ua kev ua tau zoo (lub zog ntau dua lossis sib npaug nrog 35 CN / DTEX, modulus ntau dua lossis sib npaug rau 1200 CN / DTEX).

UHMWPE Manufacturing Process

 

 

1. Cov Khoom Siv Raw Khoom Siv

 

1.1 Txhab Xaiv Cov Qauv

  • Molecular hnyav: 3.5 × 10⁶ ~ 1.2 × 10 teev g / mol (kuaj ib ISO 16014)

  • Molecular Nyhav Fetabation Index (PDI):<3.5 (GPC measurement)
  • Catalyst tseem nyob qis qis: tsawg dua los yog sib npaug rau 5 ppm (ICP-MS Nrhiav tau)
  • Crystallinity: ntau dua los yog sib npaug rau 85% (DSC ntsuas)

1.2 cov kuab tshuaj kho kom zoo

  • Decalin / Paraffin Roj Compositesiab(7: 3 Piv)
  • Cov kev daws teeb meem: {{3-8 wt% (kho raws li cov txheej txheem kiv)
  • Tswj Kub Tswj Kub: 130 ± 2 Qib (PID-Sib Sau Ua Ntej Reactor)

 

2. Cov Txheej Txheem Txheej Txheem Kev Ntsuam Xyuas

 

2.1 Gel Spinning System

Tswj tsis:

  • Spinning kub gradient: 180 degree → 140 degree → 90 degree (peb-cheeb tsam tswj)
  • Cua-Hack ntev: 5-15 cm (kho los ntawm cov fiber ntau)
  • Thawj Fiber Crystallinity: 40-50%

2.2 ultra-kos duab txheej txheem

Peb-theem nruam ncab:

Ntxiv dag zog rau cov txheej txheem:

  • Molecular saw orientation ntau dua los yog sib npaug rau 95%
  • Lamellar Crystal Thickness: 30-50 nm (saxs txheeb xyuas)
  • Fiber Ntau<0.5% (mercury intrusion porosimetry)

 

3. Nto Hloov Kho Tshuab


3.1 Plasma Kev Kho Mob

  • Atmospheric HO NTSHAV NTSHAV HASHMA JET (APP)
  • Lub Hwj Chim: 300-500 w
  • Duration: 30-120 s
  • Nto Zog Ua Haujlwm: 45 → 72 MN / M (Lub Xeem Kev Ntsuas Xyuas)

3.2 nanocoating

  • Qhov tsua ntawm Coupling Openment gradient txheej ({0}} nm thickness)
  • Polyurethane / Epoxy Composite Txheej (300% Hnav Kuj Zoo)
  • UV blocking rate >99% ({280-400 nm wavelength)

Electron tsom tsom Tsom (SEM / TEM) → The Breatment tsom xam (GPC) → Kev tshawb xyuas qhov hnyav (XPS

 

5. Technology Kev Tsim Kho Kev Loj Hlob

 

  • Melt Spinning Alternatives (Rhuav 3.5 × 10⁶ molecular qhov hnyav hnyav.
  • Kev loj hlob bio raws li kev txhim kho (hloov cov tshuab decalin)
  • Ntse Fiber R & D (sib xyaw ua ke lub luag haujlwm)
  • Circular recycling processes (solvent recovery rate >99.5%)
