Umehluko Phakathi kwe-LLDPE ne-LDPE
Umehluko phakathi kwe-linear low density polyethylene (LLDPE) kanye ne-low density polyethylene (LDPE) 1. Incazelo I-linear low density polyethylene (LLDPE) kanye ne-low density polyethylene (LDPE) kokubili yizinto zepulasitiki ezitholakala ku-ethylene njengento yokuqala eluhlaza. Nokho, ziyehluka ngokwesakhiwo; I-LLDPE ilungiswa kusetshenziswa ubuchwepheshe be-catalyst eyodwa, okuholela ekwakhekeni komugqa kanye nokuminyana okuphezulu, kanti i-LDPE inokwakheka kweketango okungajwayelekile nokuminyana okuphansi. 2. Izakhiwo ezibonakalayo i-LLDPE ibonisa umehluko ohlukile ngokuya ngokuminyanaFunda kabanzi …
Ukuhlukanisa i-High density polyethylene (HDPE) kusukela ku-LDPE
I-High density polyethylene (HDPE) kanye ne-low density polyethylene (LDPE) yizinhlobo ezimbili zama-polymers e-polyethylene anezakhiwo ezihlukile. Nawu umehluko obalulekile phakathi kwawo: 1. Isakhiwo se-Molecular: I-HDPE inesakhiwo esiwumugqa esinamagatsha amancane, okuholela ekubeni kube nokuminyana okuphezulu kanye nokucwebezela. I-LDPE, ngakolunye uhlangothi, inesakhiwo esinamagatsha amaningi futhi esingajwayelekile, okuholela ekukhuleni okuphansi kanye nokucwebezela okuncane. 2. Ukuminyana: Njengoba igama liphakamisa, i-High density polyethylene (HDPE) inokuminyana okuphezulu uma kuqhathaniswa nokuphansi.Funda kabanzi …
Iyini i-high density polyethylene plastic?
I-High-density polyethylene (HDPE) iwuhlobo lwepulasitiki olubonakala ngesilinganiso salo samandla aphezulu ukuya kokuminyana. Isetshenziswa kakhulu ezinhlelweni ezahlukahlukene ngenxa yokumelana kwayo namakhemikhali okuhle kakhulu, ukuqina, nokuguquguquka. I-HDPE ikhiqizwa nge-polymerization yama-ethylene monomers, okuholela kuchungechunge lwe-polymer eqondile enezinga eliphezulu le-crystallinity. I-HDPE yaziwa ngobuningi bayo obuphezulu, obunikeza amandla aphakeme nokuqina uma kuqhathaniswa nezinye izinhlobo ze-polyethylene. Inokuminyana isuka ku-0.93 iye ku-0.97Funda kabanzi …
