Amapuleti e-polyethylene lokhu kungenxa yokuthi amaketanga amangqamuzana kwesinye isikhathi avimba ama-photocrystals awo, ashiye isifunda esikhulu se-amorphous ku-biomolecule, amapuleti e-polyethylene angamunca amandla amaningi e-kinetic. Ngokwereferensi, indlela ye-astm- D256 isetshenziselwa ukunquma umthelela wenani lamandla okucindezela epulasitiki. Ngokuqhathanisa, amandla okucindezela ebhodi le-polyethylene angahlukaniswa abe yi-polycarbonate, i-polycarbonate iyaziwa ngokumelana nomthelela, futhi ingasetshenziswa njengemikhiqizo yenjoloba evamile.
Ukumelana nokungqubuzana kwepuleti le-polyethylene kuphansi kakhulu. Ibhodi le-polyethylene linokumelana okungcono nokugqokwa, ukumelana nokungqubuzana okuphansi kanye nokuzinza kahle. Kuyimpahla yephupho ye-bushing, roller kanye ne-bushing. Ukukhethwa kwebhodi le-polyethylene njenge-friction pair, hhayi nje kuphela kungathuthukisa impilo yesevisi eyonakele yezikhungo, ibhodi le-polyethylene futhi lingagcina izinsiza.
Ibhodi le-polyethylene linokumelana okuhle kwamakhemikhali. Ibhodi le-polyethylene linokumelana okungcono kwamakhemikhali. Ngaphezu kwe-nitric acid egxilile ne-sulfuric acid, ibhodi le-polyethylene akulula ukuqoshwa kunoma yisiphi isisombululo se-alkaline noma esine-acidic. Ingasetshenziswa njenge-dilute hydrochloric acid ku-80 ℃, ku-sodium cyanide & LT; I-Hydrochloric acid & lt; I-75% ebushelelezi, ingasetshenziswa futhi ngamanzi nokuhlanza okuwuketshezi. Njengoba wonke umuntu azi, ibhodi le-polyethylene lilula kakhulu ukuvuvukala kuma-hydrocarbons aliphatic noma ama-halogenates (ikakhulukazi ekushiseni okuphezulu okuqhubekayo), ngakho-ke kufanele kuqashelwe ukusetshenziswa kwayo.
Thuthukisa ukumelana nokugqokwa kwebhodi le-polyethylene. Ukumelana nokugqoka okuphezulu kungenye yezici ezilingayo, ibhodi le-polyethylene kumaphrojekthi amaningi ekusetshenzisweni kwenani elibalulekile lokusetshenziswa. Kulesi sigaba, wonke amabhodi epulasitiki e-polyethylene anokumelana okuhle nokugqokwa, futhi ngisho nezinto eziningi zensimbi azivamile njengakuqala. Ngokuthuthukiswa kwesisindo samangqamuzana e-polyethylene yokucindezela okuphezulu, ukumelana nokugqokwa kwalolu hlobo lwezinto kuyathuthukiswa. Ukuphikiswa komthelela kwebhodi le-polyethylene. Amandla acindezelayo epuleti le-polyethylene ahlobene nesisindo sawo samangqamuzana. Lapho isisindo samangqamuzana esihlobene singaphansi kwezigidi ezi-2, amandla okucindezela umthelela wepuleti le-polyethylene ayanda ngokukhula kwesisindo samangqamuzana esihlobene, futhi inani eliphakeme lingaba izigidi ezimbili. Kuleli qophelo, amandla okucindezela komthelela azokwehla ngokunyuka kwesisindo samangqamuzana ahlobene.
