I-Polyethylene inokuqina okuhle kwamakhemikhali futhi ingamelana ne-nitric acid ehlanjululwe, i-sulfuric acid ehlanjululwe kanye nanoma yikuphi ukugcwala kwe-hydrochloric acid, i-hydrofluoric acid, i-phosphoric acid, i-formic acid, i-acetic acid, i-ammonia, i-amine, i-hydrogen peroxide, i-sodium hydroxide, i-potassium hydroxide nezinye izixazululo izinga lokushisa legumbi.Kodwa alimelani nokugqwala okuqinile kwe-oxidation, njenge-fuming sulfuric acid, i-nitric acid egxilile, i-chromic acid nengxube ye-sulfuric acid.Emazingeni okushisa asekamelweni, izincibilikisi zizokhiqiza ukuguguleka kancane kwe-polyethylene, futhi ku-90 ~ 100 ℃, i-sulfuric acid egxilile kanye ne-nitric acid egxilile izoyiqeda ngokushesha i-polyethylene, iyenze ilimale noma ibole. i-polyethylene.Ukusabela okufana nokuphambana, ukunqanyulwa kwamaketanga kanye nokwakheka kwamaqembu angagcwele unsaturated kungenzeka ngemva kwemisebe.
Intambo ye-polyethylene ingeye-alkane inert polymer futhi inokuqina okuhle kwamakhemikhali.Ezinga lokushisa elivamile, i-asidi, i-alkali, isixazululo esinamanzi samanzi ukumelana nokugqwala, kodwa hhayi i-oxidant eqinile njenge-fuming sulfuric acid, i-nitric acid egxilile ne-chromic acid. 60℃, kodwa nge-aliphatic hydrocarbon, i-hydrocarbon enephunga elimnandi, i-halogenated hydrocarbon nokunye ukuthintana kwesikhathi eside kuzovuvukala noma kuqhekeke.
Intambo ye-polyethylene inokukhiqizwa kwe-polyethylene, i-polyethylene yokucindezeleka kwemvelo (isenzo samakhemikhali kanye nemishini) izwela kakhulu, ukuguga kokushisa kubi kakhulu kunesakhiwo samakhemikhali e-polymer kanye nomdwebo wokucubungula.I-polyethylene ingacutshungulwa ngendlela evamile yokubumba i-thermoplastic.Isetshenziswa kabanzi ekwakhiweni kwefilimu, izinto zokupakisha, iziqukathi, amapayipi, i-monofilament, intambo nekhebula, izidingo zansuku zonke, njll., futhi ingasetshenziswa njengezinto ezisetshenziswa kakhulu zokufaka imvamisa ye-TV, i-radar, njll.Ngokuthuthukiswa kwemboni ye-petrochemical, ukukhiqizwa. ye-polyethylene iye yathuthukiswa ngokushesha, ibalwa cishe nge-1/4 yokukhiqizwa okuphelele kwamapulasitiki.Ngo-1983, umthamo womhlaba wonke wokukhiqiza we-polyethylene wawungu-24.65 mT, futhi umthamo wesitshalo esakhiwa wawungu-3.16 mT.Imiphumela yakamuva yezibalo ngo-2011, amandla okukhiqiza emhlabeni wonke afinyelela ku-96 MT, umkhuba wokuthuthukiswa kokukhiqizwa kwe-polyethylene ubonisa ukuthi ukukhiqizwa nokusetshenziswa kuyashintsha kancane kancane e-Asia, futhi i-China iba imakethe yabathengi ebaluleke kakhulu.
