Izithuthi ze-HDPE (izithuthi ze-High-Density Polyethylene) ziyakhiwa ngokusebenzisa i-High-Density Polyethylene njengezinto ezisisekelo futhi ziyathakelwa ukuze zibe nenkomo. Iziqu zabo zokuphelele ziyizinye zokuba zingaphansi kodwa zingaqhele, zingasindiswa ngamandla okuhlanza, zingasindiswa ngamandla okubhaka, zinamagugu amhlophe angcono, zinamandla okuhlanganisa okuphelele, nokude kokusebenza. Zisetshenziswa kabanzi emisebenzini yezinfrastraktsha zasezulwini, emisebenzini yezindlu, emisebenzini yezindlela, emisebenzini yamazibuko, emisebenzini yezilwanyana, nezinye izimo, futhi zinakwakhiwa ngokusebenzisa imithambo yokuvala noma imithambo yokungavalwa.
Iziqu Zokuphelele
- Isilimi nesikhathi sokusebenza: Umkhahlelo wokuphakama kungu-0.95g/cm³, akasikho isibonelo; isikhathi sokusebenza esingaphakathi kwezinsuku ziyizigidi ezingu-50, futhi ziyakhulula ngokuphelele.
- Ukubambisana nokugcina ukuthwasa: Kuyabambisana nezinkampani eziphakeme, nezinkampani ezingaphakeme, nezinsimbi; akabambisani nezinkampani ezingaphelele ekuthwaseni / izihlangu sezinkampani / izihlangu sezinsimbi; ukuthwasa okuhle kweminyaka yezinkampani; kusetshenziswa kusukela ku-60°C ku-60°C; kubambisana nokufika kwezinsuku kanye nokuthwasa kwezinkampani.
- Ukusebenza okuhle kwezinkampani zokugcina: Amagqabi amhlophe angafanele, umphumela we-Manning ungukuphakama kwe-0.009; ngokufanayo kokuphakama, umkhahlelo wokugcina kwizinkampani ziyizigidi ezingu-30% okuphakemeyo kunezinkampani zokuziphatha; akakhi amathuba.
- Isifanayo esincane futhi sikhulu: Sihlukumeza kuphela 1/8 yamapipi wezinkolo, isikhundla sekhethelelo se-ring SN4–SN16, ukubambisana kwezinkinga zokuphatha kuyisivinini esine ngokulinganisa nezinkolo; kufanele usebenze ekuthumelweni kwemithombo eyisibonelo.
- Ukuxhuma okuholela: Ukuxhuma kwezinkolo (≥75mm), ukuxhuma kwezinkolo zokugcina (yiliphi na umlinganiso, kuhle kangaka kumapipi amancane noma emazindaweni athile); ubunzima bewa-join ≥ ubunzima bempipi; ukususa kungasebenzisa izihlombe zokuxhuma ezifanelwe.
