Vaega
1. Fa'aleleia atili le fa'alavalava.O se tasi o mea e sili ona mataʻina o le UHMW polyethylene o lona maualuga maualuga o le abrasion resistance, lea e taua tele i le tele o talosaga faʻainisinia.I totonu o palasitika uma, o lona ofuina o le teteʻe e sili ona lelei, ma e oʻo lava i le faʻaogaina masani o le tele o mea uʻamea (e pei o le carbon steel, stainless steel, bronze, ma isi) e le lelei e pei o.A'o fa'atupula'ia le mamafa mole mole o le polyethylene, o le mea e fai e sili atu ona fa'afefete.
2. Fa'ato'a maualuga le a'afiaga.Ole malosi ole a'afiaga ole polyethylene mole mole maualuga maualuga e feso'ota'i ma lona mamafa mole.Pe a laʻititi le mamafa o le mole i le 2 miliona, e faʻateleina le malosi o le aʻafiaga i le faʻaopoopoga o le mamafa o le mole, ma oʻo atu i le maualuga pe a ma le 2 miliona.A maeʻa le tumutumu, o le malosi o le aʻafiaga e faʻateleina i le mamafa mole.o le a faaitiitia.E mafua ona o le filifili mole e le masani ma taofia lona photocrystallization, ina ia i ai se itulagi amorphous tele i le macromolecule, lea e mafai ona mitiia se malosi aafiaga tele.
3. Fa'ase'e maualalo maualalo.UHMWPE e matua'i fa'alavalava, e maualalo le fa'a'ese'esega ma lelei le lubrication o ia lava, ma o se mea lelei mo le tu'uina o la'au, fa'ase'e ma linings.
O le faʻaaogaina o le polyethylene mole mole maualuga maualuga e pei o se vaega feteʻenaʻi o meafaigaluega e le gata ina faʻaleleia ai le ola faʻafefe, ae faʻasaoina foi le malosi.
4. Lelei faʻamalosi kemikolo.Ultra-maualuga molecular mamafa polyethylene e lelei le tetee corrosion kemikolo.Vagana ai le nitric acid concentrated ma concentrated sulfuric acid, o le a le pala i vaifofo uma lye ma acid, ma e mafai ona faaaoga i le concentrated hydrochloric acid i le vevela (80°C, E mautu foi i <20% nitric acid, < 75% sulfuric acid, ma e mautu foi i le vai, fufulu vai.)
Ae ui i lea, o le polyethylene mamafa maualuga-maualuga e matua faigofie lava ona fulafula i mea manogi poʻo halogenated (aemaise lava i lalo o tulaga maualuga o le vevela), o lea e tatau ai ona totogi faʻapitoa i le taimi o le faʻaoga.
5. E matua maualalo le mitiia o le vai.O le UHMWPE e maualalo tele le faʻafefe o le vai, e toetoe lava a le faʻafefe, e le fula i le vai, ma e sili atu le faʻafefe nai lo le nailon.
6. Mea tau vevela.E tusa ai ma le metotia a le ASTM (uta 4.6kg / cm2), o le vevela vevela vevela e 85 ℃.I lalo o se uta laʻititi, e mafai ona oʻo i le 90 ℃ le vevela o le auaunaga.I tulaga faʻapitoa, e faʻatagaina e faʻaaoga i se maualuga maualuga.O le polyethylene mamafa mole mole maualuga o se mea e sili ona faigata, o lona uiga laʻititi laʻititi e lelei tele, ma o loʻo i ai pea se tikeri o le faʻamalosi i le maualalo o le vevela o le -269 ° C, ma e leai se faʻailoga o le faʻaleagaina.
7. Mea tau eletise.UHMWPE o loʻo i ai mea eletise sili ona lelei i le lautele o le vevela, o lona voluma tetee o le 10-18CM, o lona gau gau o le 50KV / mm, ma o lona dielectric tumau o le 2.3.I le lautele o le vevela ma le tele o taimi, o ona mea eletise e suia tele.I totonu o le vevela vevela, e fetaui lelei mo le faʻaogaina o mea faʻapipiʻi i le inisinia eletise ma mea i fale pepa.
8. E leai se mea oona ultra-maualuga molecular mamafa polyethylene e le tofo, e le oona, odorless, e le corrosive, ma e physiological taamilosaga ma physiological fetuutuunai.O le United States Food and Drug Administration (FDA) ma le United States Department of Agriculture (USDA) faʻatagaina e faʻaaogaina i le faʻafesoʻotaʻi ma meaʻai ma vailaʻau.
O ona uiga, aemaise lava le ofuina o le tete'e, a'afiaga tete'e, ma le lava-lubricating meatotino, e sili ona lelei i totonu o palasitika inisinia.
