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 we-Raw material we-PP kanye ne-MFPP Izinto ezingavuthiwe ze-PP zilungiswa nge-polymerizing propylene ku-petroleum. I-Propylene iwumkhiqizo we-petrochemical ikakhulukazi otholakala ngenqubo yokuqhekeka ezindaweni zokucwenga. I-polypropylene MFPP eguquliwe 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. Nokho, 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.
