I-Polyethylene PE1000 Sheet – UHMWPE-Restant-Resistant
Isishwankathelo
I-Polythylene PE 1000 sheet edla ngokubhekiswa kuyo njenge-ultra-high-molecular-weight, UHMW, okanye i-UHMWPE, yenye yeeplastiki zethu ezidumileyo zobunjineli.Inika ukuchasana okugqwesileyo kwi-abrasion, iikhemikhali, impembelelo kunye nokunxiba, kwaye ibonelela ngentsebenziswano ephantsi kakhulu yokukhuhlane.I-UHMW nayo ayinayo ityhefu, ayinavumba, kwaye iyaxhathisa kakhulu kuninzi.
Iphepha leplastiki le-UHMW liqhele ukwenziwa ngoomatshini libe yimicu yokunxiba, izikhokelo zamatsheyini kunye namalungu okutshintsha kwaye yiplastiki yobunjineli ethandwayo ekusetyenzweni kokutya kunye nokusebenza kweebhotile.Amabakala athile e-PE1000 nawo asetyenziswa kwizicelo zokuphatha izinto ezininzi ukwenza ii-chute, ii-hoppers kunye neelori zokulahla, ezinceda ukuphucula ukuhamba kwemveliso kunye nokuthintela ngokuchasene ne-ratholing kunye ne-arching.

Iimbonakalo
1. Ukuphucula ukumelana nokunxiba.Enye yezona zinto zibalaseleyo ze-UHMW i-polyethylene kukuxhathisa kwayo okuphezulu ngokugqithisileyo, exabiseke kakhulu kwizicelo ezininzi zobunjineli.Phakathi kwazo zonke iiplastiki, ukuxhathisa kwayo kokugqoka kuyona nto ibhetele, kwaye kunye nokunyanzeliswa kokugqoka rhoqo kwezinto ezininzi zetsimbi (ezifana ne-carbon steel, insimbi engenasici, i-bronze, njl.) ayilunganga njengayo.Njengoko ubunzima be-molecular ye-polyethylene bunyuka, izinto eziphathekayo ziba yinto enqabileyo yokunxiba.
2. Ukumelana nempembelelo ephezulu kakhulu.Amandla empembelelo ye-ultra-high molecular weight polyethylene inxulumene nobunzima bayo be-molecular.Xa ubunzima be-molecular bungaphantsi kwe-2 yezigidi, amandla empembelelo ayanda ngokunyuka kwe-molecular weight, kwaye afikelele kwi-peak malunga ne-2 yezigidi.Emva kokuphakama, amandla empembelelo ayanda kunye nobunzima be-molecular.iya kunqaba.Oku kungenxa yokuba i-molecular chain ayiqhelekanga kwaye ithintela i-photocrystallization yayo, ukuze kubekho indawo enkulu ye-amorphous kwi-macromolecule, enokuthi ifunxe amandla amakhulu empembelelo.
3. I-coefficient ye-friction ephantsi.I-UHMWPE ayigugi kakhulu, ine-coefficient ephantsi yokukhuhlane kunye nokuzithambisa okulungileyo, kwaye iyimathiriyeli efanelekileyo yokuthwala i-bushings, izilayidi kunye ne-linings.
Ukusetyenziswa kwe-ultra-high molecular weight polyethylene njengenxalenye ye-friction yesixhobo ayikwazi nje ukuphucula ubomi obunganyangekiyo, kodwa nokugcina amandla.
4. Ukumelana neekhemikhali ezilungileyo.I-polyethylene ye-Ultra-high molekyuli inokumelana nokukhawuleza kweekhemikhali.Ngaphandle kwe-asidi ye-nitric egxininisiweyo kunye ne-sulfuric acid egxininisiweyo, ayiyi kugqwala kuzo zonke izisombululo ze-lye kunye ne-asidi, kwaye ingasetyenziselwa i-hydrochloric acid egxininisiweyo kwiqondo lokushisa (80 ° C, Iphinde izinzile <20% nitric acid, < I-75% ye-asidi ye-sulfuric, kwaye izinzile emanzini, ukuhlamba ulwelo.)
Nangona kunjalo, i-ultra-high molecular weight polyethylene ilula kakhulu ukudumba kwi-aromatics okanye i-halogenated compounds (ingakumbi phantsi kweemeko eziphezulu zokushisa), ngoko ke ingqalelo ekhethekileyo kufuneka ihlawulwe ngexesha lokusetyenziswa.
5. Ukufunxa amanzi aphantsi kakhulu.I-UHMWPE inomlinganiselo ophantsi kakhulu wokufunxa amanzi, phantse ayifunxanga, ayidumbi emanzini, kwaye ayifunxanga kangako kunenayiloni.
6. Iimpawu ze-Thermal.Ngokwendlela ye-ASTM (umthwalo we-4.6kg/cm2), ubushushu bokuguqula ubushushu bungama-85℃.Ngaphantsi komthwalo omncinci, ubushushu benkonzo bunokufikelela kwi-90℃.Kwiimeko ezikhethekileyo, kuvunyelwe ukusebenzisa kwiqondo lokushisa eliphezulu.I-polyethylene yobunzima bemolekyuli yinto enobunzima obuhle kakhulu, ngoko ke ukuchasana kwayo okuphantsi kuhle kakhulu, kwaye kusenomlinganiselo othile we-ductility kwiqondo lokushisa eliphantsi le-269 ° C, kwaye akukho phawu lwe-embrittlement.
7. Iimpawu zombane.I-UHMWPE ineempawu ezibalaseleyo zombane kuluhlu olubanzi lobushushu, ukumelana nomthamo wayo yi-10-18CM, i-voltage yayo yokuphuka yi-50KV / mm, kwaye i-dielectric constant yi-2.3.Kwiqondo elibanzi lobushushu kunye noluhlu lwamaza, iimpawu zayo zombane zitshintsha kancinci kakhulu.Kuluhlu lweqondo lokushisa elikwazi ukumelana nobushushu, lifaneleke kakhulu ukusetyenziswa njengezinto zesakhiwo kubunjineli bombane kunye nezixhobo zokugaya amaphepha.
8. I-polyethylene ene-non-toxic ultra-high molecular weight ayinancasa, ayinatyhefu, ayinavumba, ayinamhlwa, kwaye inomjikelezo we-physiological kunye nokuguquguquka komzimba.I-United States Food and Drug Administration (FDA) kunye neSebe lezoLimo laseMelika (USDA) livumela ukuba lisetyenziswe ngokudibana nokutya kunye namayeza.
Iimpawu zayo, ngakumbi ukuxhathisa ukunxiba, ukuxhathisa impembelelo, kunye neempawu zokuzithambisa, zezona zibalaseleyo phakathi kweeplastiki zobunjineli.
