Analysis na albarkatun kasa Properties na HDPE biyu bango bellows,
HDPE guduro don bangon bango biyu, yadda za a zabi resin HDPE don bangon bango biyu,

Abubuwan buƙatu na gabaɗaya don kaddarorin polyethylene (PE) sun haɗa da ƙimar narkewa (MFR), yawa, flexure elastic modulus da lokacin shigar da iskar shaka (OIT), ƙarfin tasiri, da sauransu. Abubuwan gwajin kuma sun haɗa da ƙarfin ƙarfi, elongation a hutu, ash. , marasa ƙarfi da sauran lokacin shigar da iskar shaka yana ƙayyade lokacin lalacewar oxidation.Don bellows da ke buƙatar shekaru 50 na amfani, sarrafa lokacin shigar da iskar shaka na albarkatun ƙasa shine mabuɗin don tabbatar da rayuwar sabis na shekaru 50.An bayyana a fili a cikin GB/T19472.1-2004 cewa lokacin shigar da iskar shaka na albarkatun kasa ya kamata ya zama ≥20min (200 ℃).

Modules na roba na resin HDPE yana da babban tasiri akan taurin zobe.Kayayyakin da ke da madaidaicin modules na roba na iya inganta ƙunsar zobe na samfuran, amma kuma adana albarkatun ƙasa da rage farashi a ƙarƙashin yanayin tabbatar da ƙaƙƙarfan zobe.Don haka a cikin samar da bangon bango biyu na HDPE, kayan da aka yi amfani da su yakamata su kasance da madaidaicin elasticity.Girman adadin narkewar ruwa yana nuna girman nauyin kwayoyin halitta.Gabaɗaya magana, kayan da ke da ƙimar narke mafi girma yana da amfani ga sarrafawa da haɓakawa, kuma yana iya haɓaka haɓakar samarwa.Duk da haka, ba zai iya zama babba ba, wanda ke da tasiri mafi girma a kan ƙullun zobe.A lokaci guda, dole ne ya sami babban yawa da kyakkyawan aikin sarrafawa da daidaitawar kayan aiki.

HDPE bututu grade yana da fadi ko bimodal rarraba nauyi kwayoyin.Yana da juriya mai ƙarfi mai ƙarfi da ma'auni mai kyau na rigidity da tauri.Yana da ɗorewa kuma yana da ƙananan sag lokacin da ake sarrafa shi.Bututun da aka samar ta amfani da wannan guduro suna da ƙarfi mai kyau, tsayin daka da juriya mai tasiri da kyawawan kayan SCG da RCP.

Ya kamata a adana guduro a cikin busasshiyar ma'ajiyar ajiya kuma daga wuta da hasken rana kai tsaye.Bai kamata a tara shi a sararin sama ba.A lokacin sufuri, kada a fallasa kayan zuwa hasken rana mai ƙarfi ko ruwan sama kuma kada a kwashe su tare da yashi, ƙasa, tarkacen ƙarfe, gawayi ko gilashi.An haramta jigilar kayayyaki tare da mai guba, abu mai lalacewa da mai ƙonewa.
