Dab tsi yog Ultra-High Molecular-Weight Polyethylene (UHMWPE)

Polyethylene yog cov yas siv ntau tshaj plaws hauv lub ntiaj teb, tab sis koj yuav ua li cas thiaj paub tias nws yog cov xov paj zoo rau koj daim ntawv thov?Xav txog cov yam ntxwv ntawm ultra-high-molecular-weight polyethylene (UHMWPE) - ib qho nyuaj subset ntawm polyethylene uas muaj zog rau qhov hnyav piv 8-15 npaug ntau dua li cov hlau.

Feem ntau paub los ntawm cov npe lag luam ntawm Spectra® thiab Dyneema®, UHMWPE plastics thiab yarns feem ntau yog siv rau:

· Kev siv Ballistic (Lub Cev Armor, Armor Plating)

· Kev ua si thiab kev lom zem (skydiving, skiing, nkoj, nuv ntses)

· Ropes thiab cordage

· Cov khoom siv ntau

· Porous qhov chaw thiab lim

· Automotive kev lag luam

· Kev lag luam tshuaj

· Khoom noj khoom haus thiab dej haus machinery

· Cov khoom siv mining thiab ntxhia ua khoom siv

· Cov khoom siv tsim khoom

· Civil engineering thiab earthmoving equipment

· Cov ntawv thov kev thauj mus los, suav nrog cov tsheb thauj khoom, cov thawv ntim khoom thiab cov hoppers.

Raws li koj tuaj yeem pom UHMWPE muaj ntau hom kev siv los ntawm kev tsim khoom mus rau kev kho mob nrog rau hauv cov ntawv siv hlau thiab cable.Qhov no yog vim nws cov npe ntev ntawm cov txiaj ntsig uas ua tau raws li cov cai tshwj xeeb rau ntau txoj haujlwm sib txawv.

Qhov zoo ntawm UHMWPE suav nrog, tab sis tsis txwv rau:

· Kev tiv thaiv zoo heev rau kev ntxhov siab thiab siab tiv thaiv kev tawg

· Abrasion hnav tsis kam - 15 npaug ntau dua rau kev puas tsuaj dua li cov hlau

· Nws 40% Muaj zog dua Aramid yarns

· Nws muaj zog tshuaj tiv thaiv - heev resilient rau feem ntau alkalis thiab acid, organic solvents, degreasing agents thiab electrolytic nres

· Nws yog non-toxic

· Zoo heev dielectric zog

· Self-lubricating - tsawg coefficient ntawm kev sib txhuam (piv rau PTFE)

· Tsis staining

· FDA pom zoo siv rau hauv daim ntawv thov zaub mov thiab kho mob

· Tsawg lub ntiajteb txawj nqus - yuav ntab hauv dej

Thaum qhov no yuav zoo li cov khoom siv zoo tagnrho, kuj tseem muaj qee qhov tsis zoo uas koj yuav tsum paub txog.UHMWPE muaj qhov qis melting point (297 ° txog 305 ° F) dua li ntau cov polymers, yog li nws tsis haum rau cov ntawv thov kub.Nws kuj muaj qhov coefficient tsawg ntawm kev sib txhuam uas tuaj yeem ua qhov tsis zoo nyob ntawm daim ntawv thov.UHMWPE yarns kuj tuaj yeem tsim "ntoo" nyob rau hauv ib qho kev thauj khoom tas li, uas yog cov txheej txheem ntawm cov elongation ntawm cov fibers.Qee tus neeg yuav xav txog tus nqi yog qhov tsis zoo, txawm li cas los xij thaum nws los txog UHMWPE, tsawg dua.Muab lub zog ntawm cov khoom siv no koj yuav tsis tas yuav ntau npaum li koj xav nrog lwm cov ntaub ntawv.
