Ishidi le-Polyethylene PE1000 – I-UHMWPE I-Wear-Resistant
Isifinyezo
Ishidi le-Polythylene PE 1000 elivame ukubizwa ngokuthi i-ultra-high-molecular-weight, UHMW, noma i-UHMWPE, ingelinye lamapulasitiki ethu onjiniyela aziwa kakhulu.Inikeza ukumelana okuhle kakhulu nemihuzuko, amakhemikhali, umthelela kanye nokuguga, futhi inikeza ukungqubuzana okuphansi kakhulu.I-UHMW futhi ayinabo ubuthi, ayinaphunga, futhi imelana kakhulu ne- mosture.
Ishidi lepulasitiki le-UHMW livamise ukufakwa ngomshini libe yizicucu, iziqondiso zamaketango nezingxenye ezishintshayo futhi liyipulasitiki yobunjiniyela ethandwayo ekucubunguleni ukudla nasekufakeni amabhodlela.Amabanga athile e-PE1000 nawo asetshenziswa ezinhlelweni zokuphatha izinto eziningi ukuze alayini ama-chute, ama-hopper namaloli alahlayo, okusiza ukuthuthukisa ukugeleza komkhiqizo nokuvimbela ngokumelene ne-ratholing kanye ne-arching.

Izici
1. Thuthukisa ukumelana nokugqoka.Enye yezinto ezigqama kakhulu ze-UHMW polyethylene ukumelana kwayo nokuhuzuka okuphakeme kakhulu, okuwusizo olukhulu ezinhlelweni eziningi zobunjiniyela.Phakathi kwawo wonke amapulasitiki, ukumelana nokugqoka kwawo kungcono kakhulu, ngisho nokumelana nokugqoka okuvamile kwezinto eziningi zensimbi (njenge-carbon steel, insimbi engagqwali, ithusi, njll.) akulungile njengayo.Njengoba isisindo samangqamuzana e-polyethylene sikhula, izinto ezibonakalayo ziba ukumelana kakhulu nokugqoka.
2. Ukumelana nomthelela ophakeme kakhulu.Amandla omthelela we-polyethylene yesisindo samangqamuzana aphezulu kakhulu ahlobene nesisindo sayo samangqamuzana.Uma isisindo samangqamuzana singaphansi kwezigidi ezi-2, amandla omthelela ayanda ngokukhula kwesisindo samangqamuzana, futhi afinyelela inani eliphakeme cishe ezigidini ezimbili.Ngemva kokuphakama, amandla omthelela akhula ngesisindo samangqamuzana.izokwehla.Lokhu kungenxa yokuthi uchungechunge lwamangqamuzana aluvamile futhi luvimbela i-photocrystallization yayo, ukuze kube nesifunda esikhulu se-amorphous ku-macromolecule, engakwazi ukumunca amandla omthelela omkhulu.
3. I-coefficient ye-friction ephansi.I-UHMWPE ayigugi kakhulu, ine-coefficient ephansi yokungqubuzana kanye nokuzigcoba okuhle, futhi iyimpahla efanelekile yokuthwala ama-bushings, amaslayidi nama-linings.
Ukusetshenziswa kwe-polyethylene yesisindo se-molecular ultra-high njengengxenye yokungqubuzana kwemishini ayikwazi nje ukuthuthukisa impilo yokugqoka, kodwa futhi yonga amandla.
4. Ukumelana okuhle kwamakhemikhali.I-polyethylene enesisindo esiphakeme kakhulu samangqamuzana inokumelana nokugqwala kwamakhemikhali okuhle.Ngaphandle kwe-nitric acid egxilile kanye ne-sulfuric acid egxilile, ngeke idliwe kuzo zonke izixazululo ze-lye ne-asidi, futhi ingasetshenziswa ku-hydrochloric acid egxilile ekushiseni (80 ° C, Iphinde izinzile ku-<20% nitric acid, < 75% sulfuric acid, futhi izinzile emanzini, ukugeza okuwuketshezi.)
Kodwa-ke, i-polyethylene yesisindo se-molecular ultra-high kulula kakhulu ukuvuvukala kumakhemikhali aphunga noma ama-halogenated (ikakhulukazi ngaphansi kwezimo eziphakeme zokushisa), ngakho-ke kufanele kukhokhwe ukunakwa okukhethekile ngesikhathi sokufaka isicelo.
5. Ukumuncwa kwamanzi okuphansi kakhulu.I-UHMWPE inezinga eliphansi kakhulu lokumunca amanzi, cishe ayimundi, ayivuvukali emanzini, futhi ayimunci kakhulu kunenayiloni.
6. Izakhiwo ezishisayo.Ngokwendlela ye-ASTM (umthwalo ongu-4.6kg/cm2), izinga lokushisa lokuhlanekezela ukushisa lingu-85℃.Ngaphansi komthwalo omncane, izinga lokushisa lesevisi lingafinyelela ku-90℃.Ezimweni ezikhethekile, kuvunyelwe ukusebenzisa ekushiseni okuphezulu.I-polyethylene yesisindo samangqamuzana aphezulu iyinto enokuqina okuhle kakhulu, ngakho-ke ukumelana kwayo okuphansi nakho kuhle kakhulu, futhi kusenayo izinga elithile le-ductility ekushiseni okuphansi kwe--269 ° C, futhi akukho sibonakaliso sokugubha.
7. Izakhiwo zikagesi.I-UHMWPE inezici ezinhle kakhulu zikagesi ebangeni elibanzi lokushisa, ukumelana nevolumu yayo kungu-10-18CM, i-voltage yayo yokuqhekeka ingu-50KV/mm, kanti i-dielectric constant yayo ingu-2.3.Ezingeni elibanzi lokushisa kanye nemvamisa, izici zayo zikagesi zishintsha kancane kakhulu.Ebangeni lokushisa elimelana nokushisa, lifaneleka kakhulu ukusetshenziswa njengezinto zesakhiwo kubunjiniyela bakagesi kanye nezinto ezigayweni zephepha.
8. I-polyethylene enesisindo se-ultra-high engeyona enobuthi ayinambitheki, ayinabuthi, ayinaphunga, ayigqwali, futhi inomjikelezo wokuphila nokuvumelana nezimo.I-United States Food and Drug Administration (FDA) kanye noMnyango Wezolimo wase-United States (i-USDA) iyayivumela ukuthi isetshenziswe lapho kuthintana nokudla nemithi.
Izici zayo, ikakhulukazi ukumelana nokugqokwa, ukumelana nomthelela, kanye nezakhiwo zokuzigcoba, zihamba phambili phakathi kwamapulasitiki obunjiniyela.
