Ukuba sifuna ukwazi ukusetyenziswa kwe-polymer polyethylene, kufuneka siqale sazi iimpawu zayo kunye neenzuzo, ezinokuthi zisetyenziswe ngokubanzi kwaye zibe nezicelo ezinamandla.
Intambo yePolyethylene ludidi oluphezulu, kwaye iDinima, eNetherlands, imele ngoku.Ngokungathandabuzekiyo, amandla e-polyethylene enziwe nge-high-molekyuli yaseChina asemalunga ne-10% ephantsi kunaleyo, kodwa inenzuzo ekusebenzeni kweendleko kunye nomthamo wokuthengisa.Ngenxa yokuba umahluko wamandla we-10% unokulungiswa ngokunyusa kancinci ububanzi.Nangona kunjalo, iinkampani zasekhaya ze-polymer R&D kunye namaziko ahlala ephucuka, kwaye amandla abo ahlala ephucuka, kwaye aya kuhlala egqitha kumazwe angaphandle.Ukhuphiswano kuphela olunokwenza abathengisi bezinto eziluhlaza bahlale bephucula umgangatho wabo.
Umlinganiselo we-polyethylene kumanzi ngu-0.97: 1, onokuhamba phezu kwamanzi, kunye ne-elongation ye-4% kuphela kunye ne-melting point ye-150. Kubalulekile ukuchasana kwe-UV kunye ne-asidi kunye ne-alkali ukumelana.
Ezi mpawu zingabonakalisa ukuba zingasetyenziswa kwezinye iindawo ezine-asidi eyomeleleyo kunye nokubola kwealkali njengokukhanya kwelanga, amanzi olwandle, njl njl. Okubaluleke ngakumbi, amandla ayo phantsi kobukhulu obufanayo angaphezulu kwamaxesha angama-6 kwezinye izinto eziqhelekileyo, kunye nobunzima bayo kwakhona ukukhanya.Ukuba kufuneka amandla afanayo, ububanzi bentambo ye-polyethylene ephezulu ye-molecular ingenziwa encinci, kwaye ubunzima bayo buphindwe kaninzi, ngoko kulula ukuyisebenzisa kwaye ifanelekile ukusetyenziswa kwiindawo ezibalulekileyo ezifana neenqanawa ezinkulu kunye neenqanawa zemfazwe.Ngokomzekelo, inayiloni yi-72mm * 220, inamandla eetoni ezili-102 kunye nobunzima be-702KG.Ukuba sifuna ukufikelela kwinqanaba le-102 yeetoni, kufuneka sikhethe kuphela ububanzi be-44mm ukukhetha i-polyethylene ephezulu ye-molecular, kunye nobunzima be-220m yi-215KG kuphela.Ngokuthelekisa, sinokubona ngokucacileyo iingenelo ezinkulu zentambo ye-polymer polyethylene!
Ukusetyenziswa okwaziwayo,
Okokuqala, i-polypropylene filament, i-polyester, inayiloni kunye nezinye izinto zinokutshintshwa ngamandla apho zifakwe khona, njengemigca yokuxhoma, imigca yokutsala, iintambo ezinkulu zeenqanawa kunye neenqanawa zemfazwe.
Okwesibini, buyisela iintambo zentsimbi, ezifana neentambo zewintshi zezithuthi, iintambo zokutsala umbane kunye neenethi zokuloba elwandle nokuloba, ezinokusetyenziswa.
Emva koko, ndifuna ukugqamisa amandla akhe, ukukhanya, ukuxhathisa kwe-asidi kunye ne-alkali kunye nokuchasana nokuguga, ukuze ndiqinisekise ukuba uya kuba nesikhundla esiphezulu kule mimandla kwixesha elizayo.
Kwixesha elizayo, ukusetyenziswa kwe-polymer polyethylene kuya kuba kwindawo ephezulu, kwaye abantu ngokuqinisekileyo abayi kukhetha iintambo eziqhelekileyo ezinobunzima kunye namandla aphantsi.Ngokhuphiswano phakathi kwabathengisi bezinto eziluhlaza, ixabiso lezinto ezibonakalayo liya kuhla ngokuqinisekileyo, eliya kuba lisondele kubantu, kwaye iintambo ze-polymer polyethylene ziya kuba yimveliso eqhelekileyo!
