Ishidi le-Polyethylene PE1000 – Imelana Nokugqokwa kwe-UHMWPE
Isifinyezo
Ishidi le-Polythylene PE 1000 elivame ukubizwa ngokuthi yi-ultra-high-molecular-weight, i-UHMW, noma i-UHMWPE, ingenye yepulasitiki yethu yobunjiniyela ethandwa kakhulu. Inikeza ukumelana okuhle kakhulu nokuguguleka, amakhemikhali, umthelela kanye nokuguguleka, futhi inikeza ukusebenza okuphansi kakhulu kokungqubuzana. I-UHMW nayo ayinabo ubuthi, ayinaphunga, futhi imelana kakhulu ne-mosture.
Ishidi lepulasitiki le-UHMW livame ukucutshungulwa libe yimichilo yokuguguleka, iziqondiso zamaketanga kanye nezingxenye zokushintsha futhi liyipulasitiki yobunjiniyela ethandwayo ekusebenzeni kokucubungula ukudla kanye nokufaka amabhodlela. Amazinga athile e-PE1000 asetshenziswa nasezinhlelweni zokuphatha izinto eziningi ukuze kufakwe ama-chutes, ama-hopper kanye namaloli okulahla udoti, okusiza ekuthuthukiseni ukugeleza komkhiqizo nokuvimbela ukuguguleka nokugoba.

Izici
1. Thuthukisa ukumelana nokuguguleka. Esinye sezimpawu eziphawuleka kakhulu ze-UHMW polyethylene ukumelana kwayo nokuguguleka okuphezulu kakhulu, okubaluleke kakhulu ezicelweni eziningi zobunjiniyela. Phakathi kwazo zonke ipulasitiki, ukumelana kwayo nokuguguleka kungcono kakhulu, futhi ngisho nokumelana nokuguguleka okuvamile kwezinto eziningi zensimbi (njengensimbi yekhabhoni, insimbi engagqwali, ithusi, njll.) akukuhle njengayo. Njengoba isisindo sama-molecule se-polyethylene sanda, izinto ziba nzima ukuguguleka.
2. Ukumelana nomthelela ophezulu kakhulu. Amandla omthelela we-polyethylene enesisindo sama-molecule aphezulu kakhulu ahlobene nesisindo sayo sama-molecule. Lapho isisindo sama-molecule singaphansi kwezigidi ezimbili, amandla omthelela ayanda ngokukhuphuka kwesisindo sama-molecule, futhi afinyelela esicongweni esingaba yizigidi ezimbili. Ngemva kwesicongo, amandla omthelela ayanda ngesisindo sama-molecule. Lokhu kungenxa yokuthi uchungechunge lwama-molecule alujwayelekile futhi luvimbela i-photocrystallization yalo, ukuze kube nesifunda esikhulu esingenasimo ku-macromolecule, esingamunca amandla amakhulu omthelela.
3. I-coefficient ephansi yokungqubuzana. I-UHMWPE imelana kakhulu nokuguguleka, ine-coefficient ephansi yokungqubuzana kanye nokuzigcoba okuhle, futhi iyinto efanelekile yama-bushings, ama-slider kanye nama-lining.
Ukusetshenziswa kwe-polyethylene enesisindo sama-molecule ephezulu kakhulu njengengxenye yokungqubuzana kwemishini akugcini nje ngokuthuthukisa impilo evikela ukuguguleka, kodwa futhi nokonga amandla.
4. Ukumelana okuhle kwamakhemikhali. I-polyethylene enesisindo sama-molecule aphezulu kakhulu inokumelana okuhle kokugqwala kwamakhemikhali. Ngaphandle kwe-nitric acid egxilile kanye ne-sulfuric acid egxilile, ngeke igqwale kuzo zonke izixazululo ze-lye ne-asidi, futhi ingasetshenziswa ku-hydrochloric acid egxilile ekushiseni (80°C, futhi izinzile ku-<20% i-nitric acid,<75% i-sulfuric acid, futhi izinzile emanzini, ekugezeni ngoketshezi.)
Kodwa-ke, i-polyethylene enesisindo sama-molecule aphezulu kakhulu kulula kakhulu ukuyivuvukalisa kuma-compounds ane-aromatic noma i-halogenated (ikakhulukazi ngaphansi kwezimo zokushisa eziphakeme), ngakho-ke kufanele kunakwe ngokukhethekile ngesikhathi sokufaka.
5. Ukumuncwa kwamanzi okuphansi kakhulu. I-UHMWPE inesilinganiso esiphansi kakhulu sokumuncwa kwamanzi, cishe ayimuncwi, ayivuvuki emanzini, futhi ayimuncwi kakhulu kune-nylon.
6. Izakhiwo zokushisa. Ngokwendlela ye-ASTM (umthwalo ongu-4.6kg/cm2), izinga lokushisa lokushintshashintsha kokushisa lingu-85℃. Ngaphansi komthwalo omncane, izinga lokushisa lesevisi lingafinyelela ku-90℃. Ezimweni ezikhethekile, kuvunyelwe ukusetshenziswa ekushiseni okuphezulu. I-polyethylene enesisindo sama-molecule ephezulu iyinto enokuqina okuhle kakhulu, ngakho-ke ukumelana kwayo okuphansi nakho kuhle kakhulu, futhi isenezinga elithile lokuguquguquka ekushiseni okuphansi okungu--269 ° C, futhi akukho sibonakaliso sokuqhekeka.
7. Izakhiwo zikagesi. I-UHMWPE inezakhiwo zikagesi ezinhle kakhulu ebangeni elibanzi lokushisa, ukumelana kwayo nomthamo kungu-10-18CM, i-voltage yayo yokuqhekeka ingu-50KV/mm, kanti i-dielectric constant yayo ingu-2.3. Ebangeni elibanzi lokushisa kanye nemvamisa, izakhiwo zayo zikagesi azishintshi kakhulu. Ebangeni lokushisa elingamelani nokushisa, ifaneleka kakhulu ukusetshenziswa njengezinto zokwakha kubunjiniyela bukagesi kanye nezinto ezisebenza emishinini yamaphepha.
8. I-polyethylene engenabo ubuthi ephezulu kakhulu ayinambitheki, ayinabo ubuthi, ayinaphunga, ayiboli, futhi inokujikeleza kwegazi kanye nokuzivumelanisa nezimo ngokomzimba. I-United States Food and Drug Administration (FDA) kanye noMnyango Wezolimo wase-United States (USDA) bayakuvumela ukuthi kusetshenziswe lapho kuhlangana nokudla nemithi.
Izici zayo, ikakhulukazi ukumelana nokuguguleka, ukumelana nokushayisana, kanye nezakhiwo zokuzigcoba, zingcono kakhulu phakathi kwepulasitiki yobunjiniyela.

Isicelo Somkhiqizo
I-polyethylene enesisindo sama-molecule esiphezulu kakhulu ibhekisela ku-polyethylene enesakhiwo esiqondile enesisindo sama-molecule esingaphezu kwezigidi ezintathu. Iyipulasitiki yobunjiniyela esebenza kahle kakhulu. Izakhiwo zayo ezinhlanu ukumelana nokuguguleka, ukumelana nokushayisana, ukumelana nokugqwala, ukuzigcoba, kanye nokumuncwa kwamandla okushayisana. Kukhona amapulasitiki amahle kakhulu, aziwa emhlabeni wonke ngokuthi "izinto ezimangalisayo".
