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 yePP kanye ne-MFPPImpahla eluhlaza ye-PP ilungiswa 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 izilungisi ezishintsha ukwakheka kwe-polymer nokwakheka 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. Ngokuxutshwa kwencibilika 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. Kuyi-aipulasitiki esobala ngobulukhuni nokuqina okuthile. Nokho, amandla nokuqina kwe-PP evamile kuphansi, okuholela ekwethulweni kwezinto eziguquliwe ezifana ne-MFPP. I-MFPP yengeza izilungisi ezithile ku-PP ukwenza i-MFPP ibe namandla angcono, ukuqina kanye nokumelana nomthelela. Iziguquli zingase futhi ziguqule ukushintshwa 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 zimbili ezivamileizinto 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 ukunethezeka nokuthuthukiswa ezimpilweni zethu kanye nezinkambu ezihlukahlukene zezimboni.
