Iiplate zePolyethylene oku kungenxa yokuba iitsheyini zeemolekyuli ngamanye amaxesha zivala iikristale zazo ze-photocrystals, zishiya ummandla omkhulu ongenasimo kwi-biomolecule, iiplate ze-polyethylene zinokufunxa amandla amaninzi e-impact kinetic. Ngokwesalathiso, indlela ye-astm-D256 isetyenziselwa ukumisela impembelelo yexabiso lamandla oxinzelelo lweplastiki. Ngokwentelekiso, amandla oxinzelelo lwebhodi ye-polyethylene anokwahlulwa abe yi-polycarbonate, i-polycarbonate yaziwa ngokuxhathisa kwayo impembelelo, kwaye ingasetyenziswa njengeemveliso zerabha ngokubanzi.
Ukumelana nokungqubana kweplate yepolyethylene kuphantsi kakhulu. Ibhodi yepolyethylene inokumelana nokuguguleka okungcono, ukumelana nokungqubana okuphantsi kunye nokuzimanzisa kakuhle. Yinto entle kakhulu eyenziwe nge-bushing, roller kunye ne-bushing. Ukukhetha ibhodi yepolyethylene njengesibini sokungqubana, akupheleli nje ekuphuculeni ubomi benkonzo eyonakeleyo yezixhobo, ibhodi yepolyethylene kwaye kunokonga izixhobo.
Ibhodi yePolyethylene inokumelana okuhle kweekhemikhali. Ibhodi yePolyethylene inokumelana okungcono kweekhemikhali. Ukongeza kwi-nitric acid egxininisiweyo kunye ne-sulfuric acid, ibhodi ye-polyethylene ayilula ukuyikrola kuyo nayiphi na isisombululo se-alkaline okanye se-asidi. Ingasetyenziswa njenge-dilute hydrochloric acid kwi-80℃, kwi-sodium cyanide kunye ne-LT; i-Hydrochloric acid kunye ne-lt; 75% egudileyo, ingasetyenziswa namanzi kunye nokucoca ulwelo. Njengoko wonke umntu esazi, ibhodi ye-polyethylene kulula kakhulu ukuyivuthulula kwi-aliphatic hydrocarbons okanye kwi-halogenates (ingakumbi kubushushu obuphezulu obuqhubekayo), ngoko ke kufuneka kuqwalaselwe ukusetyenziswa kwayo.
Ukuphucula ukumelana nokuguguleka kwebhodi ye-polyethylene. Ukumelana nokuguguleka okuphezulu yenye yeempawu ezinomtsalane, ibhodi ye-polyethylene kwiiprojekthi ezininzi ekusebenziseni ixabiso eliphambili lokusetyenziswa. Kweli nqanaba, yonke ibhodi ye-polyethylene yeplastiki inokumelana nokuguguleka okuhle, kwaye nezinto ezininzi zesinyithi aziqhelekanga njengangaphambili. Ngokuphuculwa kobunzima beemolekyuli ze-polyethylene yoxinzelelo oluphezulu, ukumelana nokuguguleka kolu hlobo lwezinto nako kuyaphucuka. Ukumelana nokuguguleka kwebhodi ye-polyethylene. Amandla okuxinzelela epleyitini ye-polyethylene anxulumene nobunzima bayo beemolekyuli. Xa ubunzima beemolekyuli bungaphantsi kwezigidi ezi-2, amandla okuxinzelela empembelelo epleyitini ye-polyethylene ayanda ngokunyuka kobunzima beemolekyuli, kwaye ixabiso eliphezulu limalunga nezigidi ezi-2. Kweli nqanaba, amandla okuxinzelela empembelelo aya kuncipha ngokunyuka kobunzima beemolekyuli.
