Ukuba sifuna ukwazi ukusetyenziswa kwe-polyethylene ephezulu ye-molecular, kufuneka siqale sazi iimpawu zayo kunye neenzuzo, ezinokuthi zisetyenziswe ngokubanzi kwaye zibe nokusetyenziswa okunamandla.
Intambo ye-molecular polyethylene yi-fiber ephezulu.I-Dutch Dyneema yangoku ngummeli.Ayinakuphikiswa into yokuba i-polyethylene eyenziwe yasekhaya eyenziwe ngemolekyuli ephezulu isenayo i-gap malunga ne-10% kunye nayo ngokwamandla, kodwa ngokubhekiselele ekusebenzeni kweendleko, kunye nenzuzo ekuthengisweni, kuba i-10% umahluko kumandla unokulungiswa. ngokunyuka okuncinci kobubanzi.Nangona kunjalo, iinkampani zasekhaya zophando kunye nophuhliso lweepolymer kunye namaziko ahlala ephucula, kwaye amandla aphuculwe, kwaye kuya kuhlala kukho ngaphezu kwamazwe angaphandle.Kuphela lukhuphiswano oluya kwenza abathengisi bezinto eziluhlaza ukuba baqhubeke bephucula umgangatho wabo.
Umlinganiselo we-polyethylene ephezulu ye-molecular kunye namanzi ngu-0.97: 1, inokudada phezu kwamanzi, i-elongation yi-4% kuphela, i-melting point: i-150, kwaye kubalulekile ukuchasana kwe-UV, i-asidi kunye ne-alkali ukumelana.
Ezi mpawu zingabonisa ukuba zingasetyenziswa kwezinye iindawo ezineasidi eyomeleleyo kunye nokubola kwealkali njengokukhanya kwelanga namanzi olwandle.Okubaluleke ngakumbi, amandla ayo angaphezu kwamaxesha angama-6 kwezinye izinto eziqhelekileyo phantsi kobubanzi obufanayo, kwaye ubunzima bayo buyakhanya.Ukuba Ngaphantsi kweemfuno zamandla afanayo, intambo ephezulu ye-molecular polyethylene ingenziwa encinci ububanzi kwaye amaxesha amaninzi ilula ngobunzima, ekulula ukuyisebenzisa kwaye ifanele imimandla ebalulekileyo njengeenqanawa ezinkulu kunye neenqanawa zemfazwe.Ngokomzekelo, inayiloni yi-72mm * 220 yeemitha, amandla angama-102 iitoni, kunye nobunzima be-702KG.Ukuba sifuna ukufikelela kwinqanaba le-102 yeetoni, kufuneka sikhethe kuphela ububanzi be-44mm kwi-polyethylene ephezulu ye-molecular, kunye nobunzima beemitha ezingama-220 yi-215KG kuphela.Ngokuthelekisa, sinokubona ngokucacileyo iingenelo ezinkulu zentambo ye-molecular polyethylene!
usetyenziso olwaziwayo ngoku,
Okokuqala, i<em>polypropylene filament, i<em>polyester, nenayiloni zinokutshintshwa ngamandla naphi na apho zifakwe khona, njengeentambo zokubophelela, iintambo zokutsala, iintambo zeenqanawa ezinkulu kakhulu, neenqanawa zemfazwe.
Okwesibini, buyisela intambo yocingo lwentsimbi, efana nentambo yocingo yefestile yezithuthi, intambo yokutsalela umbane, inethi yokulima elwandle kunye nokuloba, zonke zingasetyenziswa.
Emva koko, ndifuna ukugxininisa amandla akhe aphezulu, ukukhanya, ukuxhathisa kwe-asidi kunye ne-alkali, kunye nokuchasana nokuguga, ukugqiba ukuba uya kuba nesikhundla esiphezulu kule mimandla kwixesha elizayo.
Kwixesha elizayo, ukusetyenziswa kwe-high-molecular polyethylene kuya kulawula.Abantu ngokuqinisekileyo abayi kukhetha iintambo eziqhelekileyo ezinobunzima kunye nezisezantsi.Ngokhuphiswano phakathi kwabathengisi bezinto eziluhlaza, ixabiso lezinto ezibonakalayo liya kuhla ngokuqinisekileyo, kwaye liya kuba lisondele ngakumbi kubantu.Intambo yeVinyl iya kuba yimveliso eqhelekileyo!
