Uyini umehluko phakathi kwe-PP ne-MFPP yomkhiqizo?

I-PP (i-polypropylene) iyinto evamile yepulasitiki enokumelana okuhle nokushisa, ukumelana namakhemikhali kanye nokuminyana okuphansi.I-MFPP (i-polypropylene elungisiwe) iyimpahla ye-polypropylene eguquliwe enamandla aqinile kanye nokuqina.Kulezi zinto ezimbili, le ndatshana izohlinzeka ngesingeniso sesayensi esidumile ngokuya ngemithombo yezinto ezingavuthiwe, izinqubo zokulungiselela, izici, nezinkambu zokusetshenziswa.

1. Umthombo wempahla eluhlaza we-PP kanye ne-MFPP Impahla eluhlaza ye-PP ilungiswa nge-polymerizing propylene ku-petroleum.I-Propylene ingumkhiqizo we-petrochemical ikakhulukazi otholakala ngenqubo yokuqhekeka ezindaweni zokucwenga.I-Modified polypropylene MFPP ithuthukisa ukusebenza kwayo ngokungeza izilungisi ku-PP evamile.Lezi zilungisi zingaba izithasiselo, izigcwalisi noma ezinye iziguquli ezishintsha ukwakheka kwe-polymer ukuze zinikeze izakhiwo ezingcono zomzimba namakhemikhali.

2. Inqubo yokulungiselela i-PP ne-MFPP Ukulungiswa kwe-PP kutholakala ikakhulukazi ngokusabela kwe-polymerization.I-Propylene monomer yenziwa i-polymerized ibe iketango le-polymer lobude obuthile ngesenzo se-catalyst.Le nqubo ingenzeka ngokuqhubekayo noma ngezikhathi ezithile, emazingeni okushisa aphezulu kanye nezingcindezi.Ukulungiswa kwe-MFPP kudinga ukuxuba isilungisi kanye ne-PP.Ngokuxuba okuncibilikayo noma ukuxuba isixazululo, isilungisi sihlakazeka ngokulinganayo ku-matrix ye-PP, ngaleyo ndlela sithuthukise izakhiwo ze-PP.

3. Izici ze-PP ne-MFPP PP zinokuphikiswa okuhle kokushisa nokuzinza kwamakhemikhali.Ipulasitiki esobala enobulukhuni nokuqina okuthile.Kodwa-ke, amandla nokuqina kwe-PP evamile kuphansi, okuholela ekwethulweni kwezinto eziguquliwe ezifana ne-MFPP.I-MFPP yengeza ezinye izilungisi ku-PP ukwenza i-MFPP ibe namandla angcono, ukuqina kanye nokumelana nomthelela.Izilungisi zingaphinde ziguqule ukuguquguquka kwe-thermal, izakhiwo zikagesi kanye nokumelana nesimo sezulu kwe-MFPP.

4. Izinkambu zokufaka isicelo ze-PP ne-MFPP PP zisetshenziswa kakhulu futhi zivame ukusetshenziswa ezitsheni, ifenisha, izinto zikagesi kanye neminye imikhiqizo ekuphileni kwansuku zonke.Ngenxa yokumelana nokushisa nokumelana namakhemikhali, i-PP iphinde isetshenziswe kumapayipi, iziqukathi, ama-valve nezinye izinto zokusebenza embonini yamakhemikhali.I-MFPP ivamise ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu kanye nokuqina, njengezingxenye zezimoto, amabhokisi omkhiqizo we-elekthronikhi, izinto zokwakha, njll.

Sengiphetha, i-PP ne-MFPP yizinto ezimbili ezijwayelekile zepulasitiki.I-PP inezici zokumelana nokushisa, ukumelana nokugqwala kwamakhemikhali kanye nokuminyana okuphansi, futhi i-MFPP iguqule i-PP ngalesi sisekelo ukuze ithole amandla angcono, ukuqina kanye nokumelana nomthelela.Lezi zinto ezimbili zidlala indima ebalulekile emikhakheni ehlukene yohlelo lokusebenza, ziletha lula kanye nentuthuko ezimpilweni zethu kanye nezinkambu ezihlukahlukene zezimboni.
