Xaashiyaha Polyethylene PE1000 - UHMWPE Wear-U- adkaysta
Soo koobid
Polythylene PE 1000 xaashida loo yaqaan 'ultra-high-molecular-weight', UHMW, ama UHMWPE, waa balaastigga injineernimada ugu caansan.Waxa ay siisaa iska caabin heersare ah oo ka dhan ah nabar-goynta, kiimikooyinka, saamaynta iyo xidhashada, waxayna bixisaa iska-horimaad aad u hooseeya.UHMW sidoo kale maaha mid sun ah, ur la'aan ah, aadna ugu adkaysata inta badan.
UHMW xaashida balaastiigga ah waxaa sida caadiga ah lagu farsameeyaa xariijimaha xirashada, tilmaanta silsiladaha iyo qaybaha beddelka waana caag injineernimo oo caan ah habaynta cuntada iyo dhalooyinka.Darajooyin gaar ah oo PE1000 ah ayaa sidoo kale loo adeegsadaa codsiyada wax ka qabashada alaabta badan si loo safeeyo chutes-ka, hoppers-ka iyo baabuurta iska rogrogmada, taasoo gacan ka geysaneysa hagaajinta socodka badeecada iyo ka hortagga ratholing iyo qaanso.

Astaamaha
1. Hagaajinta iska caabbinta xidhashada.Mid ka mid ah sifooyinka ugu yaabka badan ee UHMW polyetylen waa iska caabbinta xoqidda aadka u sarreysa, taas oo qiimo weyn u leh codsiyada injineernimada.Dhammaan balaastigga, caabbinta xirashada ayaa ah tan ugu fiican, xitaa iska caabbinta xirashada joogtada ah ee alaabooyin badan oo bir ah (sida birta kaarboon, birta, naxaasta, iwm) uma fiicna sida ay tahay.Marka miisaanka molecular ee polyetylen uu kordho, maaddadu waxay noqotaa mid aad u adkaysata.
2. Iska caabin aad u sarreeya.Awoodda saamaynta aadka u sarreeya ee miisaanka unugyadu waxay la xiriirtaa miisaankiisa kelli.Marka miisaanka unugyadu uu ka hooseeyo 2 milyan, awoodda saameyntu waxay korodhaa korodhka miisaanka kelliga, oo wuxuu gaaraa meesha ugu sarreysa qiyaastii 2 milyan.Meesha ugu sarreysa ka dib, xoogga saameyntu waxay ku korodhaa miisaanka kelliyada.hoos u dhici doona.Tani waa sababta oo ah silsiladda molecular waa mid aan caadi ahayn oo xannibaysa sawir-qaadisteeda, si ay u jirto gobol weyn oo amorphous ah oo ku jira makromolecule, kaas oo nuugi kara tamar saameyn weyn leh.
3. Isku-dhafan hoose.UHMWPE waa mid aad u adkaysata xidhashada, waxa ay leedahay isfaham hoose iyo saliidayn wanaagsan, waana shay ku haboon qaadida buushka, sliders iyo dahaarka.
Isticmaalka polyetylen culeyska molecular ee aadka u sarreeya sida qaybta jajabka ee qalabka ma hagaajin karto oo kaliya nolosha xirashada, laakiin sidoo kale waxay badbaadinaysaa tamarta.
4. Iska caabin kiimiko oo wanaagsan.polyetylen miisaankeedu aad u sarreeyo wuxuu leeyahay iska caabin daxalka kiimikaad oo wanaagsan.Marka laga reebo nitric acid iyo sulfuric acid oo xoogaysan, laguma daxaloobayn doono dhammaan xalalka lye iyo aashitada, waxaana loo isticmaali karaa acid hydrochloric acid heerkulka (80 ° C, sidoo kale waxay ku xasilloon tahay <20% nitric acid, < 75% sulfuric acid, iyo sidoo kale waxay ku xasilloon tahay biyaha, dareeraha dhaqista.)
Si kastaba ha noqotee, polyetylen culeyska aadka u sarreeya waa mid aad u fudud in lagu bararo xeryahooda udgoonka ama halogenated (gaar ahaan xaaladaha heerkulka sare), markaa fiiro gaar ah waa in la bixiyaa inta lagu jiro codsiga.
5. Nuugista biyaha oo aad u hooseeya.UHMWPE waxay leedahay heerka nuugista biyaha oo aad u hooseeya, waxay ku dhowdahay inayna nuugto, kuma bararto biyaha, aad ayayna uga nuugtaa naylon.
6. Guryaha kulaylka.Marka loo eego habka ASTM (load 4.6kg/cm2), heerkulka kulaylka qalloocan waa 85 ℃.Culays yar hoostiisa, heerkulka adeeggu wuxuu gaari karaa 90 ℃.Xaalado gaar ah, waxaa loo oggol yahay in lagu isticmaalo heerkul sare.Polyethylene miisaankeedu sarreeyo waa walxo leh adkeysi aad u fiican, sidaas darteed iska caabbinta hoose ayaa sidoo kale aad u wanaagsan, welina waxay leedahay heer gaar ah oo ductility heerkul hooseeya -269 ° C, mana jirto calaamad muujinaysa.
7. Guryaha korantada.UHMWPE waxay leedahay sifooyin koronto oo heersare ah oo heerkul ballaaran ah, iska caabbinta mugga waa 10-18CM, korantada burburkeedu waa 50KV/mm, joogtaynteeda dielectric waa 2.3.Heerkulka ballaaran iyo inta jeer ee kala duwan, sifooyinka korantada ayaa isbedelaya wax yar.Heerkulka kulaylka u adkaysta, aad bay ugu habboon tahay in loo isticmaalo sida qalabka dhismaha ee injineernimada korontada iyo qalabka waraaqaha waraaqaha.
8. Miisaanka molecular ee aadka u sarreeya ee aan sunta ahayn ee polyetylen waa mid aan dhadhamin, aan sun ahayn, aan ur lahayn, aan qudhun, oo waxa uu leeyahay wareegga jireed iyo la qabsiga jireed.Maamulka Cuntada iyo Dawooyinka ee Maraykanka (FDA) iyo Waaxda Beeraha ee Maraykanka (USDA) ayaa oggol in loo isticmaalo xidhiidhka cuntada iyo daawooyinka.
Sifooyinkeeda, gaar ahaan xirashada iska caabbinta, iska caabbinta saameynta, iyo sifooyinka is-saliimaynta, ayaa ah kuwa ugu wanaagsan caagadaha injineernimada.
