Eqhelekileyo 6 Iintlobo zePolyethylene
Iintlobo ezininzi zePolyethylene
I-Polyethylene yipolymer eguquguqukayo esetyenziswa ngokubanzi kumashishini ahlukeneyo. Kukho iintlobo ezininzi ze-polyethylene, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo. Nazi ezinye zezona ntlobo zixhaphakileyo:
1. I-Low-Density Polyethylene (LDPE): I-LDPE yipolymer eguquguqukayo kunye ne-transparent kunye neqondo eliphantsi lokunyibilika. Ngokuqhelekileyo isetyenziselwa ukupakisha iifilimu, iingxowa zeplastiki, polyethylene ukutyabeka kwaye ukhame iibhotile. I-LDPE yaziwa ngokugqwesa kwayo imichiza kunye neempawu ezilungileyo zokugquma umbane.
2. I-High-Density Polyethylene (i-HDPE): I-HDPE i-polymer eqinile kwaye inzima kunye nenqanaba eliphezulu lokunyibilika. Isetyenziswa kuluhlu olubanzi lwezicelo, kubandakanya imibhobho, izikhongozeli, kunye nezinto zokudlala. I-HDPE yaziwa ngamandla ayo abalaseleyo, ukuqina, kunye nokuxhathisa imichiza kunye nemitha ye-UV.
3. I-Linear Low-Density Polyethylene (LLDPE): I-LLDPE luhlobo oluguquguqukayo nolunzima lwe-polyethylene edibanisa iimpawu ze-LDPE kunye ne-HDPE. Isetyenziswa ngokuqhelekileyo kwiifilimu zokupakisha, iifilimu zezolimo, kunye ne-geomembranes. I-LLDPE ibonelela ngokuxhathisa kokugqobhoza okulungileyo, ukomelela kokukrazula, kunye nokumelana nempembelelo.
4. I-Polyethylene ye-Medium-Density (MDPE): I-MDPE i-polymer eneempawu phakathi kwe-LDPE kunye ne-HDPE. Isetyenziswa kwizicelo ezifana nemibhobho yegesi, imibhobho yamanzi, kunye nokugquma intambo. I-MDPE inikezela ngolungelelwaniso lokuguquguquka, amandla, kunye nokumelana neekhemikhali.
5. I-Ultra-High Molecular Weight Polyethylene (UHMWPE): I-UHMWPE yipolima esebenza kakhulu enobunzima obuphezulu kakhulu bemolekyuli. Isetyenziswa kwizicelo ezifuna ukuxhathisa okungaqhelekanga, okufana neebheringi, iigiya, kunye nokufakelwa kwezonyango. I-UHMWPE ikwanokumelana neekhemikhali okugqwesileyo kunye neempawu eziphantsi zokukhuhlana.
6. I-Cross-Linked Polyethylene (PEX): I-PEX luhlobo lwe-polyethylene oluye lwahlanganiswa ngekhemikhali. Ngokuqhelekileyo isetyenziswe kwiinkqubo zemibhobho, apho inika ukuchasana okugqwesileyo kumaqondo aphezulu kunye neekhemikhali. Imibhobho yePEX iyaguquguquka, yomelele, kwaye iyaxhathisa ekudlekeni.
Le yimizekelo embalwa yeentlobo ze-polyethylene ezikhoyo. Uhlobo ngalunye luneempawu zalo ezikhethekileyo kunye neenzuzo, okwenza i-polyethylene ibe yinto eguquguqukayo kwizinto ezininzi zokusetyenziswa.
