Umahluko phakathi kwePlastiki yePP kunye nePlastiki yePE
I-PP kunye ne-PE zizinto ezimbini zeplastiki ezisetyenziswa ngokuqhelekileyo, kodwa zahluke kakhulu kwizicelo zazo. Eli candelo lilandelayo liza kuchaza umahluko phakathi kwezi zinto zimbini.
| Igama leKhemikhali | Iipolypropylene | Polyethylene |
| Ulwakhiwo | Akukho sakhiwo seTyathanga leSebe | Ulwakhiwo lweTyayina leSebe |
| mninzi | 0.89-0.91g/Cm³ | 0.93-0.97g/Cm³ |
| Indawo yokunyibilika | 160-170 ℃ | 120-135 ℃ |
| Ukumelana nobushushu | Ukuxhathisa okuLungileyo koBuqondo obuPhakamileyo, kunokumelana nobushushu obungaphezulu kwe-100℃ | Ukuchasana nobushushu obuphezulu kumbi ngokwentelekiso, ngesiqhelo kunokumelana nobushushu obuphezulu 70-80℃ |
| voco | Ukuqina okuphezulu, kodwa ukuguquguquka okuphantsi | Ukuguquguquka Okulungileyo, Akukho lula Ukuqhawula |
Igama lekhemikhali, isakhiwo, ubuninzi, indawo yokunyibilika, ukumelana nobushushu, kunye nokuqina kwePP kunye ne-PE kuyahluke kakhulu njengoko kubonakala kwitheyibhile ekhankanywe ngasentla. Lo mahluko umisela izicelo zabo ezahlukeneyo.
Ngenxa yobunzima bayo obuphezulu, ubunzima obunzima, ukumelana nobushushu obuphezulu, kunye neempawu ezintle zokugquma phakathi kwezinye iimpawu, iPP isetyenziswa ngokuqhelekileyo ekuveliseni iibhokisi zeplastiki, iidramu zeplastiki, iinxalenye zemoto, izixhobo zombane njl.njl Ngakolunye uhlangothi, i-PE ifumana. usetyenziso olubanzi ekwenzeni imibhobho yamanzi, izixhobo zokugquma intambo, kunye neengxowa zokutya ngenxa yokuqina kwayo okuncomekayo, ukumelana nokunxiba, ukuthamba, kunye nokuxhathisa ubushushu obuphantsi.
Ukubonakala kwePP kunye ne-PE kunokufana, kodwa iimpawu zabo zokusebenza zihluke kakhulu. Ngoko ke, ukhetho lwezicelo kufuneka lusekelwe kwiimpawu ezithile zezinto eziphathekayo.
