9.2 lab molecular hnyav UHMWPE pas nrig
Nqe lus piav qhia:
Ultra-siab bar ua los ntawm peb lub tuam txhab muaj kev hnav zoo heev, zoo kub tsis kam cuam tshuam, nws tus kheej-lubricating, tsis muaj tshuaj lom, dej-resistant thiab tshuaj-resistant.High mechanical zog.Nws muaj qhov cuam tshuam zoo heev, kev ntxhov siab tawg ua haujlwm, kub siab creep tsis kam, tsis tshua muaj kev sib txhuam coefficient, nws tus kheej lubrication, zoo heev tshuaj corrosion kuj, qaug zog tsis kam, suab nrov damping, nuclear hluav taws xob tiv thaiv Nws tuaj yeem hloov carbon hlau, stainless hlau, tooj liab thiab lwm yam ntaub ntawv. rau textile, papermaking, zaub mov machinery, tsheb thauj mus los, kev kho mob, thee mining, tshuaj lom neeg kev lag luam thiab lwm yam lag luam.

UHMWPE Taw Qhia:
Ultra-high molecular hnyav polyethylene (UHMW-PE) yog hais txog linear polyethylene nrog qhov nruab nrab molecular hnyav ntawm ntau tshaj 1.5 lab.Vim nws qhov hnyav molecular siab heev (cov polyethylene ib txwm yog 20,000 txog 300,000, UHMW-PE muaj qhov ua tau zoo tsis sib xws piv nrog cov polyethylene zoo tib yam thiab lwm yam khoom siv yas:
1) Tsis tshua muaj siab hnav tsis kam, 4 npaug siab dua nylon 66 thiab PTFE, 6 npaug siab dua carbon steel, qhov zoo tshaj plaws ntawm tag nrho cov hluavtaws resins tam sim no.
2) Qhov cuam tshuam lub zog yog siab heev, uas yog 2 npaug ntawm polycarbonate thiab 5 npaug ntawm ABS, thiab tuaj yeem tswj tau siab tawv ntawm cov kua nitrogen kub (-196 ℃).
3) Cov khoom zoo ntawm tus kheej lubricating, nws tus kheej lubricating khoom yog sib npaug ntawm PTFE, thiab kev sib txhuam coefficient tsuas yog 0.07-0.11;Nws tsuas yog 1/4-1/3 ntawm kev sib txhuam coefficient ntawm hlau.
4) Qhov kev poob siab lub zog nqus tus nqi yog qhov siab tshaj plaws ntawm tag nrho cov yas, thiab cov nyhuv txo suab nrov yog qhov zoo heev.
5) Nws muaj tshuaj lom neeg ruaj khov thiab tuaj yeem tiv taus ntau yam corrosive media thiab organic media hauv qee qhov kub thiab txias ntau yam.
6) Muaj peev xwm tiv thaiv adhesion, thib ob tsuas yog "Plastic King" PTFE.
7) Ua kom huv si thiab tsis muaj tshuaj lom, nws tuaj yeem siv rau kev sib cuag nrog zaub mov thiab tshuaj.
8) Qhov ceev yog qhov tsawg tshaj plaws ntawm tag nrho cov yas engineering, 56% sib zog dua PTFE thiab 22% sib zog dua polycarbonate;qhov ntom yog 1/8 ntawm cov hlau, thiab lwm yam.
Vim tias qhov kev ua tau zoo tshaj plaws saum toj no, UHMW-PE hu ua "zoo li yas" los ntawm cov teb chaws Europe thiab Asmeskas thiab tau txais txiaj ntsig thiab siv dav hauv ntau lub lag luam.
