Uxinaniso oluphezulu lweBanga lombhobho wePolyethylene
Ibakala lombhobho we-HDPE linokusabalalisa okubanzi okanye kwe-bimodal ubunzima be-molecular.Inoxhathiso oluqinileyo lwe-creep kunye nokulinganisela okulungileyo kokuqina kunye nokuqina.Yomelele kakhulu kwaye ine-sag ephantsi xa isenziwa.Imibhobho eveliswa kusetyenziswa le resin inamandla amahle, ukuqina kunye nokumelana nempembelelo kunye nepropathi egqwesileyo ye-SCG kunye ne-RCP.
I-resin kufuneka igcinwe kwindawo yokugcina impahla, eyomileyo kwaye kude nomlilo kunye nelanga elithe ngqo.Akufunekanga ifunjwe kwindawo evulekileyo.Ngexesha lokuthutha, izinto eziphathekayo akufanele zibekwe kwilanga elinamandla okanye imvula kwaye akufanele zihanjiswe kunye nesanti, umhlaba, isinyithi esilahliweyo, amalahle okanye iglasi.Uthutho kunye nezinto eziyityhefu, ezidlekayo nezinokutsha akuvumelekanga ngokungqongqo.
Isicelo
Inqanaba lombhobho we-HDPE lingasetyenziselwa ukuveliswa kwemibhobho yoxinzelelo, njengemibhobho yamanzi ecinezelekileyo, imibhobho yegesi yepetroli kunye neminye imibhobho yoshishino.Isenokusetyenziswa ukwenza imibhobho engacinezelekiyo njengemibhobho etyatyiweyo enodonga oluphindwe kabini, imibhobho yodonga olunomngxuma, imibhobho yesilicon-core, imibhobho yokunkcenkceshela yezolimo kunye nemibhobho edityanisiweyo ye-aluminiyamplastics.Ukongeza, nge-extrusion esebenzayo (i-silane cross-linking), ingasetyenziselwa ukuvelisa imibhobho ye-polyethylene edibeneyo (PEX) yokubonelela ngamanzi abandayo nashushu.
