Umehluko Phakathi kwe-PP Plastic ne-PE Plastic
I-PP ne-PE ziyizinto ezimbili zepulasitiki ezisetshenziswa kakhulu, kodwa zihluke kakhulu ekusetshenzisweni kwazo. Isigaba esilandelayo sizochaza umehluko phakathi kwalezi zinto ezimbili. Igama Lekhemikhali Isakhiwo se-Polypropylene Polyethylene Akukho Isakhiwo Se-Branching Chain Isakhiwo Se-Branched Chain Ubuningi 0.89-0.91g/Cm³ 0.93-0.97g/Cm³ Indawo Yokuncibilika 160-170℃ 120-135℃ Ukumelana Nokushisa Okuhle Ukumelana Nokushisa Okuphezulu, Kungamelana Nokushisa Okungaphezu Kuka-100℃ Ukumelana Nokushisa Okuphezulu Kubi Kakhulu, Ngokuvamile Kungamelana Nokushisa Okuphezulu Okungu-70-80℃ Ukuqina Okuphezulu Ukuqina Okuphezulu, Kodwa Ukuguquguquka Okubi Ukuguquguquka Okuhle, Funda Okwengeziwe …
Umehluko Phakathi kwe-LLDPE ne-LDPE
Umehluko phakathi kwe-polyethylene eqondile ephansi (LLDPE) kanye ne-polyethylene ephansi ephansi (LDPE) 1. Incazelo I-polyethylene eqondile ephansi ephansi (LLDPE) kanye ne-polyethylene ephansi ephansi (LDPE) zombili ziyizinto zepulasitiki ezithathwe ku-ethylene njengezinto eziyinhloko zokusetshenziswa. Kodwa-ke, ziyahlukahluka ngokwesakhiwo; i-LLDPE ilungiswa kusetshenziswa ubuchwepheshe obuyi-catalyst eyodwa, okuholela esakhiweni esiqondile kanye nobuningi obuphezulu, kanti i-LDPE inesakhiwo seketanga esingajwayelekile esinobuningi obuphansi. 2.

Ukuhlukanisa i-High density polyethylene (HDPE) kusukela ku-LDPE
I-polyethylene enobukhulu obuphezulu (i-HDPE) kanye ne-polyethylene enobukhulu obuphansi (i-LDPE) yizinhlobo ezimbili zama-polymer e-polyethylene anezakhiwo ezihlukile. Nansi umehluko obalulekile phakathi kwawo: 1. Isakhiwo sama-Molecular: I-HDPE inesakhiwo esiqondile esinamagatsha amancane, okuholela ekuxineni okuphezulu kanye nokukristala. Ngakolunye uhlangothi, i-LDPE inesakhiwo esinamagatsha amaningi futhi esingajwayelekile, okuholela ekuxineni okuphansi kanye nokukristala okuncane. 2. Ubuningi: Njengoba igama lisikisela, i-polyethylene enobukhulu obuphezulu (i-HDPE) inobukhulu obuphezulu uma kuqhathaniswa nobukhulu obuphansi Funda Okwengeziwe …
Iyini i-high density polyethylene plastic?
I-polyethylene enamandla kakhulu (i-HDPE) uhlobo lwepulasitiki olubonakala ngesilinganiso sayo samandla aphezulu kuya kobuningi. Ivame ukusetshenziswa ezinhlotsheni ezahlukene ngenxa yokumelana kwayo okuhle kwamakhemikhali, ukuqina, kanye nokuguquguquka.
