Isishwankathelo
Iphepha lePolythylene PE 1000 elidla ngokubizwa ngokuba yi-ultra-high-molecular-weight, i-UHMW, okanye i-UHMWPE, yenye yezona plastiki zethu zobunjineli zidumileyo. Inika ukumelana okuhle kakhulu nokukrazuka, iikhemikhali, impembelelo kunye nokuguguleka, kwaye ayiniki mandla aneleyo okukhuhlana. I-UHMW ayinabungozi, ayinavumba, kwaye ayixhathisi kakhulu kwiimbotyi.
Iphepha leplastiki le-UHMW lidla ngokwenziwa ngomatshini libe yimicu yokuguguleka, izikhokelo zetyathanga kunye neendawo zokutshintsha kwaye yiplastiki yobunjineli edumileyo kwimisebenzi yokulungisa ukutya kunye nokufaka iibhotile. Amanqanaba athile e-PE1000 akwasetyenziswa kwizicelo zokuphatha izinto ezininzi kwiichutes, iihoppers kunye neelori zokulahla inkunkuma, ukunceda ukuphucula ukuhamba kwemveliso kunye nokuthintela ukuqhekeka kunye nokugoba.

Iimbonakalo
1. Ukuphucula ukumelana nokuguguleka. Enye yezona mpawu zibalaseleyo ze-UHMW polyethylene kukumelana kwayo nokuguguleka okuphezulu kakhulu, okubaluleke kakhulu kwizicelo ezininzi zobunjineli. Phakathi kwazo zonke iiplastiki, ukumelana kwayo nokuguguleka yeyona ilungileyo, kwaye nokumelana nokuguguleka okuqhelekileyo kwezinto ezininzi zesinyithi (ezifana nentsimbi yekhabhoni, intsimbi engatyiwayo, ibronze, njl.njl.) akulunganga njengayo. Njengoko ubunzima bemolekyuli ye-polyethylene busanda, izinto ziya ziguguleka ngakumbi.
2. Ukumelana nempembelelo ephezulu kakhulu. Amandla empembelelo ye-polyethylene enobunzima be-molecular ephezulu kakhulu anxulumene nobunzima bayo be-molecular. Xa ubunzima be-molecular bungaphantsi kwezigidi ezi-2, amandla empembelelo ayanda ngokunyuka kobunzima be-molecular, aze afikelele kwincopho emalunga nezigidi ezi-2. Emva kwencopho, amandla empembelelo ayanda ngobunzima be-molecular. aya kuncipha. Oku kungenxa yokuba i-molecular chain ayiqhelekanga kwaye iyayithintela i-photocrystallization yayo, ukuze kubekho ummandla omkhulu ongenasimo kwi-macromolecule, onokufunxa amandla amakhulu empembelelo.
3. I-coefficient ephantsi yokungqubana. I-UHMWPE ayigugi kakhulu, inomlinganiselo ophantsi wokungqubana kwaye iyazithambisa kakuhle, kwaye sisixhobo esifanelekileyo sokufaka iibhereyitha, izilayida kunye nee-linings.
Ukusetyenziswa kwe-polyethylene enobunzima obuphezulu kakhulu njengenxalenye yokungqubana kwezixhobo akunakuphucula kuphela ubomi obungagugiyo, kodwa kunokonga amandla.
4. Ukumelana kakuhle kweekhemikhali. I-polyethylene enobunzima obuphezulu kakhulu inokumelana okuhle kokubola kweekhemikhali. Ngaphandle kwe-asidi ye-nitric exineneyo kunye ne-asidi ye-sulfuric exineneyo, ayizukubola kuzo zonke izisombululo ze-lye kunye ne-asidi, kwaye ingasetyenziswa kwi-asidi ye-hydrochloric exineneyo kubushushu (80°C, Ikwazinzile kwi-asidi ye-nitric engaphantsi kwama-20%, i-asidi ye-sulfuric engaphantsi kwama-75%, kwaye izinzile nakwisihlambi samanzi.)
Nangona kunjalo, i-polyethylene enobunzima obuphezulu kakhulu kulula kakhulu ukuyidumba kwiikhompawundi ezinevumba elimnandi okanye ezine-halogenated (ingakumbi phantsi kweemeko zobushushu eziphezulu), ngoko ke kufuneka kunikwe ingqalelo ekhethekileyo ngexesha lokufaka.
5. Ukufunxwa kwamanzi okuncinci kakhulu. I-UHMWPE inesantya esiphantsi kakhulu sokufunxwa kwamanzi, phantse ayifunxwa, ayidumbi emanzini, kwaye ayifunxwa kakhulu kune-nylon.
6. Iipropati zobushushu. Ngokwendlela ye-ASTM (umthwalo we-4.6kg/cm2), ubushushu bokujika kobushushu yi-85℃. Phantsi komthwalo omncinci, ubushushu benkonzo bunokufikelela kwi-90℃. Kwiimeko ezikhethekileyo, kuvumelekile ukuyisebenzisa kubushushu obuphezulu. I-polyethylene enobunzima obuphezulu bemolekyuli yinto enobunzima obugqwesileyo, ngoko ke ukumelana kwayo okuphantsi nako kulungile kakhulu, kwaye isenomlinganiselo othile wokuguquguquka kubushushu obuphantsi be--269 ° C, kwaye akukho phawu lokuqhekeka.
7. Iimpawu zombane. I-UHMWPE ineempawu zombane ezibalaseleyo kuluhlu olubanzi lobushushu, ukumelana kwayo nomthamo yi-10-18CM, i-voltage yayo yokuqhekeka yi-50KV/mm, kwaye i-dielectric constant yayo yi-2.3. Kuluhlu olubanzi lobushushu kunye ne-frequency, iimpawu zayo zombane azitshintshi kangako. Kuluhlu lobushushu obungatshisi ubushushu, ifanelekile kakhulu ukusetyenziswa njengezixhobo zokwakha kubunjineli bombane kunye nezixhobo kwiimveliso zephepha.
8. I-polyethylene engenabungozi kakhulu ayinancasa, ayinabungozi, ayinavumba, ayinamhlwa, kwaye inokujikeleza kwegazi emzimbeni kwaye iyakwazi ukuziqhelanisa nemizimba. I-United States Food and Drug Administration (FDA) kunye neSebe lezoLimo lase-United States (USDA) zivumela ukuba isetyenziswe xa kudibene nokutya kunye namayeza.
Iimpawu zayo, ingakumbi ukuxhathisa ukuguguleka, ukuxhathisa impembelelo, kunye neempawu zokuzithambisa, zezona zibalaseleyo phakathi kweplastiki zobunjineli.
