Yintoni umahluko phakathi kwezinto zemveliso zePP kunye neMFPP?

I-PP (i-polypropylene) yinto eqhelekileyo yeplastiki enokumelana kakuhle nobushushu, ukumelana neekhemikhali kunye noxinano oluphantsi. I-MFPP (i-polypropylene eguquliweyo) yinto ye-polypropylene eguquliweyo enamandla kunye nokuqina okuqinileyo. Kwezi zinto zimbini, eli nqaku liza kubonelela ngentshayelelo yesayensi ethandwayo malunga nemithombo yezinto eziluhlaza, iinkqubo zokulungiselela, iimpawu, kunye neendawo zokusetyenziswa.

1. Umthombo wezinto ezikrwadaI-PP kunye ne-MFPPIzinto eziluhlaza zePP zilungiswa ngokupholisha ipropylene kwipetroleum. Ipropylene yimveliso yepetrochemical efunyanwa kakhulu ngenkqubo yokuqhekeka kwiindawo zokucocisa. I-MFPP yepolypropylene eguquliweyo iphucula ukusebenza kwayo ngokongeza iimodifiers kwiPP eqhelekileyo. Ezi modifiers zinokuba zezongezo, izizalisi okanye ezinye iimodifiers ezitshintsha isakhiwo sepolymer kunye nokwakheka kwayo ukuze inike iipropati zomzimba nezekhemikhali ezingcono.

2. Inkqubo yokulungiselela i-PP kunye ne-MFPP Ukulungiswa kwe-PP kwenziwa ikakhulu nge-polymerization reaction. I-propylene monomer i-polymerized ibe yi-polymer chain enobude obuthile ngesenzo se-catalyst. Le nkqubo inokwenzeka ngokuqhubekayo okanye ngamaxesha athile, kumaqondo obushushu aphezulu kunye noxinzelelo. Ukulungiswa kwe-MFPP kufuna ukuxuba i-modifier kunye ne-PP. Ngokuxutywa kwe-melt okanye ukuxuba isisombululo, i-modifier isasazeka ngokulinganayo kwi-PP matrix, ngaloo ndlela iphucula iipropati ze-PP.

3. Iimpawu zePP kunye neMFPP I-PP inokumelana kakuhle nobushushu kunye nozinzo lweekhemikhali. Yintoiplastiki ecacileyo enobunzima obuthile kunye nokuqina. Nangona kunjalo, amandla kunye nokuqina kwe-PP eqhelekileyo kuphantsi kakhulu, nto leyo ekhokelela ekungenisweni kwezinto eziguquliweyo ezifana ne-MFPP. I-MFPP yongeza ezinye izilungisi kwi-PP ukwenza i-MFPP ibe namandla angcono, ukuqina kunye nokumelana nempembelelo. Izilungisi zinokutshintsha ukuhanjiswa kobushushu, iimpawu zombane kunye nokumelana nemozulu kwe-MFPP.

4. Iindawo zokusetyenziswa zePP kunye neMFPP I-PP isetyenziswa kakhulu kwaye isetyenziswa kakhulu kwizikhongozeli, ifenitshala, izixhobo zombane kunye nezinye iimveliso kubomi bemihla ngemihla. Ngenxa yokumelana kwayo nobushushu kunye nokumelana neekhemikhali, i-PP ikwasetyenziswa kwiipayipi, izikhongozeli, iivalvu kunye nezinye izixhobo kushishino lweekhemikhali. I-MFPP idla ngokusetyenziswa kwizicelo ezifuna amandla aphezulu kunye nokuqina, njengeenxalenye zeemoto, iikheyiji zemveliso ze-elektroniki, izinto zokwakha, njl.njl.

Ukuqukumbela, i-PP kunye ne-MFPP zimbini izinto ezifanayoizinto zeplastiki. I-PP ineempawu zokuxhathisa ubushushu, ukumelana nokugqwala kweekhemikhali kunye noxinano oluphantsi, kwaye i-MFPP iguqule i-PP ngesi siseko ukuze ifumane amandla angcono, ukuqina kunye nokumelana nempembelelo. Ezi zinto zimbini zidlala indima ebalulekileyo kwiindawo ezahlukeneyo zokusetyenziswa, zizisa ukulula kunye nophuhliso kubomi bethu nakwiindawo ezahlukeneyo zoshishino.
