Sifooyinka xaashida polyethylene ee miisaanka aadka u sarreeya ee molecular

Polyethylene-ka miisaanka molecular-ka aadka u sarreeya (UHMW-PE) waa walax injineernimo oo thermoplastic ah oo isku daraysa dhammaan faa'iidooyinka balaastikada. Iyada oo leh iska caabinta xirashada, iska caabinta saameynta, iska caabinta daxalka kiimikada, saliidaynta u gaarka ah, isku-dhafka iska caabinta xirashada heerkulka hooseeya waa yar yahay, miisaan fudud, nuugista tamarta, iska caabinta gabowga, ka-hortagga ololka, ka-hortagga iyo waxqabadka kale ee aadka u fiican, isticmaalka warshadda korontada ee dahaarka saxanka UHMW-PE, warshadda dhuxusha, dhuxusha dhuxusha ee warshadda coking; Macdanta iyo walxaha kale ee sibidhka ee warshadda sibidhka, warshadda birta iyo warshadda aluminium; Badarka, quudinta, bakhaarka warshadaha dawooyinka, haanta markabka, iwm., waxay ka hortagi kartaa walxaha dhegdheg leh, waxay dedejin kartaa xawaaraha quudinta, waxay baabi'in kartaa shilalka laba-laabka ah, waxay badbaadin kartaa maalgashiga iyo kharashka qoriga hawada, haynta badan ee dahaarka waxay ka fogaan kartaa ku dhegganaanta budada ee haynta waxayna yareyn kartaa waxyeelada mashiinnada rarista iyo dejinta ee madaxa bulkhead. Iyadoo la horumarinayo tignoolajiyada farsamaynta balaastikada, goobta codsiga ee UHMW-PE waxay noqon doontaa mid ballaaran.

A, iska caabin sare oo xirasho ah, sababtoo ah qaab-dhismeedkeeda gaarka ah ee molecular-ka, iska caabinta xirashadu waxay ka sarreysaa badeecadaha guud ee balaastikada birta ah, 6.6 jeer birta kaarboon, 5.5 jeer birta aan miridhku lahayn, 27.3 jeer naxaas, 6 jeer nayloon, 5 jeer ptfe;

B, waxqabad wanaagsan oo is-saliideyn ah, isku-darka is-jiidjiid yar, iska caabin yar oo socodka ah, keydinta tamarta;

C, xoog saameyn sare leh, adkeysi wanaagsan, xitaa heerkulka hooseeya, saameyn xooggan ma jabi doonto;

D, iska caabin kiimiko oo aad u fiican, iska caabin (marka laga reebo aashitada sulfuric ee xoogga badan, aashitada nitric ee xoogga badan, wakiil awood dabiici ah oo yar) ku dhawaad ​​​​dhammaan aashitada, alkali, iyo dhexdhexaadka milixda;

E, aan sun ahayn, aan dhadhan lahayn, aan lahayn wax lagu shubo;

F, sifooyin koronto oo wanaagsan, nuugista biyaha oo aad u yar;

G, iska caabin aad u fiican oo ku wajahan dillaaca cadaadiska deegaanka, 200 jeer ka badan polyethylene-ka caadiga ah;

H, iska caabin heerkul hooseeya oo aad u fiican, oo aan jabin xitaa -180C °.
