Amapuleti e-polyethylene lokhu kungenxa yokuthi izintambo zama-molecule ngezinye izikhathi zivimba ama-photocrystals azo, zishiya indawo enkulu engenasimo ku-biomolecule, amapuleti e-polyethylene angamunca amandla amaningi e-impact kinetic. Ngokusho kwereferensi, indlela ye-astm-D256 isetshenziswa ukunquma umthelela wenani lamandla okucindezela epulasitiki. Ngokusho kokuqhathanisa, amandla okucindezela ebhodi le-polyethylene angahlukaniswa abe yi-polycarbonate, i-polycarbonate yaziwa ngokumelana kwayo nomthelela, futhi ingasetshenziswa njengemikhiqizo yerabha ejwayelekile.
Ukumelana nokungqubuzana kwepuleti le-polyethylene kuphansi kakhulu. Ibhodi le-polyethylene linokumelana okungcono kokuguguleka, ukumelana nokungqubuzana okuphansi kanye nokuzimanzisa okuhle. Kuyinto eluhlaza ephusheni ye-bushing, i-roller kanye ne-bushing. Ukukhetha ibhodi le-polyethylene njenge-friction pair, akugcini nje ngokuthuthukisa impilo yesevisi eyonakele yezikhungo, ibhodi le-polyethylene futhi kungonga izinsiza.
Ibhodi le-polyethylene linokumelana okuhle kwamakhemikhali. Ibhodi le-polyethylene linokumelana okungcono kwamakhemikhali. Ngaphezu kwe-nitric acid egxilile kanye ne-sulfuric acid, ibhodi le-polyethylene akulula ukuliqopha kunoma yisiphi isisombululo se-alkaline noma se-acid. Lingasetshenziswa njenge-hydrochloric acid encibilikisiwe ku-80℃, ku-sodium cyanide kanye ne-LT; i-Hydrochloric acid kanye ne-lt; 75% ebushelelezi, lingasetshenziswa futhi ngamanzi kanye nokuhlanza uketshezi. Njengoba wonke umuntu azi, ibhodi le-polyethylene kulula kakhulu ukulivuvukala kuma-hydrocarbon e-aliphatic noma ama-halogenates (ikakhulukazi lapho izinga lokushisa liphezulu liqhubeka), ngakho-ke kufanele kunakwe ukusetshenziswa kwalo.
Thuthukisa ukumelana nokuguguleka kwebhodi le-polyethylene. Ukumelana nokuguguleka okuphezulu kungenye yezici ezihehayo, ibhodi le-polyethylene kumaphrojekthi amaningi ekusebenziseni inani elibalulekile lokusetshenziswa. Kulesi sigaba, wonke amabhodi e-polyethylene epulasitiki anokumelana okuhle nokuguguleka, futhi ngisho nezinto eziningi zensimbi azivamile njengakuqala. Ngokuthuthuka kwesisindo sama-molecule se-polyethylene enomfutho ophezulu, ukumelana nokuguguleka kwalolu hlobo lwezinto nakho kuyathuthuka. Ukumelana nomthelela webhodi le-polyethylene. Amandla okucindezela epuleti le-polyethylene ahlobene nesisindo salo sama-molecule. Lapho isisindo sama-molecule esihlobene singaphansi kwezigidi ezimbili, amandla okucindezela komthelela epuleti le-polyethylene ayanda ngokukhuphuka kwesisindo sama-molecule esihlobene, futhi inani eliphakeme lingaba yizigidi ezimbili. Kuleli qophelo, amandla okucindezela komthelela azoncipha ngokukhuphuka kwesisindo sama-molecule esihlobene.
