Uyini umehluko phakathi kwezinto zoMkhiqizo we-PP ne-MFPP?

I-PP (polypropylene) iyisitatimende sepulasitiki esivamile ngokumelana nokushisa okuhle, ukumelana kwamakhemikhali kanye nobuningi obuphansi. I-MFPP (i-Modified Polypropylene) iyinto eguquliwe ye-polypropylene elungisiwe ngamandla anamandla nobunzima. Kulezi zinto zokwakha ezimbili, le ndatshana izonikeza ukwethulwa kwesayensi okuthandwayo ngokuya ngemithombo yezinto ezibonakalayo, izinqubo zokulungiselela, izici, nezinkundla zohlelo lokusebenza.

1. Umthombo wezinto ezibonakalayo eziluhlaza weI-PP ne-MFPPIzinto ezivuthiwe ze-PP zilungiselelwe yi-polymerizing propylene ku-petroleum. I-PhyLyene ingumkhiqizo we-petrochemical ikakhulukazi otholwe ngenqubo yokuqhekeka kuma-conferies. I-Modified Polypropylene MFPP ithuthukisa ukusebenza kwayo ngokungeza ama-modifiers ku-PP ejwayelekile. Lezi zinguquko zingaba izithasiselo, ama-filler noma amanye ama-modiferi aguqula isakhiwo se-polymer nokwakheka ukuze akunikeze kangcono ngokomzimba nakomakhemikhali.

2. Inqubo yokulungiselela ye-PP ne-MFPP Ukulungiswa kwe-PP kutholakala kakhulu ngokusabela kwe-polymerization. I-Propellene Monomer ifakwe ku-polymer chain yobude obuthile ngesenzo se-catalyst. Le nqubo ingenzeka ngokuqhubekayo noma ngezikhathi ezithile, emazingeni okushisa aphezulu nezingcindezi. Ukulungiswa kwe-MFPP kudinga ukuxubanisa i-modifier ne-PP. Ngokusebenzisa ukuxuba ukuxubana noma ukuxubana kwesixazululo, i-modifier ihlakazeka ngokulinganayo ku-matrix ye-PP, ngaleyo ndlela yenza ngcono izakhiwo ze-PP.

3. Izici ze-PP ne-MFPP PP zinokumelana nokushisa okuhle nokuqina kwamakhemikhali. Kuyinto aipulasitiki esobala ngobulukhuni obuthile nokuqina. Kodwa-ke, amandla nobunzima be-PP elijwayelekile kuphansi, okuholela ekwethulweni kwezinto ezilungisiwe ezifana ne-MFPP. I-MFPP ingeza ama-modifiers athile ku-PP ukwenza i-MFPP ibe namandla angcono, ubulukhuni kanye nokumelana nomthelela. Ama-modifiers angashintsha futhi nokuvuselelwa okushisayo, izakhiwo zikagesi kanye nokumelana nesimo sezulu kwe-MFPP.

4. Izinkambu zohlelo lokusebenza ze-PP ne-MFPP PP zisetshenziswa kabanzi futhi zivame ukusetshenziswa ezitsheni, ifenisha, izinto zikagesi neminye imikhiqizo empilweni yansuku zonke. Ngenxa yokumelana kwayo kokushisa kanye nokumelana kwamakhemikhali, i-pp isetshenziswa futhi kumapayipi, iziqukathi, ama-valves kanye neminye imishini embonini yamakhemikhali. I-MFPP imvamisa isetshenziswa kuzinhlelo zokusebenza ezidinga amandla aphezulu kanye nobunzima, njengezinto ezinezimoto, ukuvezwa komkhiqizo we-elekthronikhi, izinto zokwakha, njll.

Ekuphetheni, i-PP ne-MFPP kuvamileIzinto zepulasitiki. I-PP inezici zokumelana nokushisa, ukumelana nokugqwala kwamakhemikhali kanye nobukhulu obuphansi, futhi i-MFPP iguquliwe i-PP ngalesi sisekelo ukuthola amandla angcono, ukuqina kanye nokuphikiswa komthelela. Lezi zinto ezimbili zokwakha zidlala indima ebalulekile emikhakheni ehlukene yohlelo, ziletha lula kanye nentuthuko ezimpilweni zethu kanye nezinkundla ezahlukahlukene zezimboni.
