High Modulus Polyethylene Textile Xov Paj

High Modulus Performance Qhov Dimensional Control Matters

High modulus polyethylene textile yarns yog tsim rau cov ntawv thov qhov chaw nruj, lub zog, thiab qhov hnyav tsawg yog qhov tseem ceeb. Lawv yog tsim los ntawm gel spinning thiab muaj nyob rau hauv ob hom: qauv thiab siab modulus. Qib ntawm molecular orientation thiab crystallinity hauv UHMWPE yog qhov siab heev. Cov kev sib cuam tshuam intermolecular muaj zog tso cai rau nws cov hlua polymer ntev ntev los thauj cov khoom thauj.

Nrog qis hygroscopicity thiab hydrolyzability, tsawg dua 1% boiling dej shrinkage, thiab superior tsis kam rau acids, alkalis, tshuaj, thiab UV teeb, UHMWPE fiber ntau exhibits lub cev kev kawm tshwj xeeb nyob rau hauv tej yam kev mob nyuaj. Nws muaj ib tug modulus ntawm 100 GPa, axial tensile zog ntawm 3 GPa, thiab thermal conductivity ntawm 20.0 W / m·K. Nws melts ntawm 144 thiab 152℃.Electrically, nws muaj resistivity saum 10¹⁴ Ω thiab dielectric zog ntawm 900 kV / cm, ua rau nws zoo haum rau siab -kev ua tau zoo engineering daim ntaub ntawv.Thaum xam seb yog hais tias daim ntawv thov xav tau ib tug ntau dua modulus los yog ib tug sib txawv kev ua tau zoo tshuav nyiaj li cas, qhov kev sib txawv yog heev pab tau.

Lightweight by Tsim

Tsawg ceev thiab siab tshwj xeeb muaj zog yog ua ke nyob rau hauv high modulus polyethylene textile xov paj. Raws li cov peev txheej, ultrahigh molecular hnyav polyethylene muaj qhov sib nqus tshwj xeeb, siab hnav tsis kam, UV stability, thiab lub zog zoo heev - rau - qhov hnyav piv. Ntxiv nrog rau qhov muaj zog oxidising acids, nws yog chemically inert thiab resists hnav thiab tsim kua muag nrog rau kev sib txhuam sab hauv. Nws qhov nqus dej tsawg thiab cov dej tsis zoo txhawb nqa nws siv hauv qhov chaw ntub dej lossis sab nraum zoov.

Kev ua thiab kev siv

Cov ntaub ntawv tuaj yeem raug coiled, coated, twisted, lossis woven. Muaj cov ntaub yarns thiab cov khoom muaj zog yog cov ntaub ntawv hais txog. Aerospace engineering, kev ua kis las sab nraum zoov, cov khoom siv hauv kev lag luam, cov khoom siv hauv nkoj thiab nuv ntses, thiab kev tiv thaiv tus kheej yog nyob ntawm thaj chaw thov. Tsis tas li ntawd, cov hlua, cables, thiab lwm yam siab - cov khoom siv hluav taws xob siab siv ultrahigh molecular hnyav polyethylene.
High modulus polyethylene textile yarns yuav tsum tau xaiv raws li ntau tshaj li lawv cov npe. Qhov kev ua tau zoo kawg yog cuam tshuam los ntawm dyneema, toughness, modulus, elongation, thiab cov khoom siv tiag tiag.
