Uthini umahluko phakathi kwePP kunye neMFPP imathiriyeli yemveliso?

I-PP (i-polypropylene) yinto eqhelekileyo yeplastiki enokumelana nokushisa okulungileyo, ukuchasana kweekhemikhali kunye nokuxinana okuphantsi.I-MFPP (i-polypropylene elungisiweyo) yimathiriyeli ye-polypropylene eguquliweyo enamandla anamandla kunye nokuqina.Kwezi zixhobo zimbini, eli nqaku liza kubonelela ngentshayelelo yesayensi edumileyo ngokwemithombo yendalo ekrwada, iinkqubo zokulungiselela, iimpawu, kunye nemimandla yesicelo.

1. Umthombo we-Raw material we-PP kunye ne-MFPP Izinto eziluhlaza ze-PP zilungiswe nge-polymerizing propylene kwi-petroleum.Ipropylene yimveliso yepetrochemical ikakhulu efunyenwe ngenkqubo yokuqhekeka kwiindawo zokucoca.I-polypropylene elungisiweyo ye-MFPP iphucula ukusebenza kwayo ngokongeza izilungisi kwi-PP eqhelekileyo.Ezi zilungisi zinokuba zizongezelelo, izigcwalisi okanye ezinye iimodyuli ezitshintsha ubume bepolymer kunye nokwakheka ukuze zinike iipropati ezingcono zomzimba kunye neekhemikhali.

2. Inkqubo yamalungiselelo e-PP kunye ne-MFPP Ukulungiswa kwe-PP kufezekiswa ikakhulu nge-polymerization reaction.I-Propylene monomer yenziwe i-polymerized kwikhonkco ye-polymer yobude obuthile ngokusebenzisa isenzo se-catalyst.Le nkqubo ingenzeka ngokuqhubekayo okanye ngokukhawuleza, kumaqondo aphezulu kunye noxinzelelo.Ukulungiswa kwe-MFPP kufuna ukuxuba isilungisi kunye nePP.Ngokuxutywa kwe-melt okanye isisombululo sokuxuba, i-modifier ihlakazwe ngokulinganayo kwi-matrix ye-PP, ngaloo ndlela iphucula iipropati zePP.

3. Iimpawu zePP kunye ne-MFPP PP inokumelana nokushisa okulungileyo kunye nokuzinza kweekhemikhali.Yiplastiki ebonakalayo enobunzima obuthile kunye nokuqina.Nangona kunjalo, amandla kunye nokuqina kwePP eqhelekileyo kuphantsi, okukhokelela ekuqalisweni kwezinto eziguquliweyo ezifana ne-MFPP.I-MFPP yongeza ezinye izilungisi kwi-PP ukwenza i-MFPP ibe namandla angcono, ukuqina kunye nokuchasana kwempembelelo.I-Modifiers inokutshintsha kwakhona i-thermal conductivity, iipropati zombane kunye nokuchasana kwemozulu ye-MFPP.

4. Iinkalo zesicelo zePP kunye ne-MFPP PP zisetyenziswa ngokubanzi kwaye zisetyenziswa ngokuqhelekileyo kwiibhokisi, ifenitshala, izixhobo zombane kunye nezinye iimveliso kwimpilo yemihla ngemihla.Ngenxa yokumelana nobushushu kunye nokumelana neekhemikhali, i-PP iphinda isetyenziswe kwimibhobho, izitya, iivalve kunye nezinye izixhobo kwishishini lemichiza.I-MFPP ihlala isetyenziswa kwizicelo ezifuna amandla aphezulu kunye nokuqina, okunje ngeendawo zeemoto, iicasing zemveliso ye-elektroniki, izinto zokwakha, njl.

Ukuqukumbela, i-PP kunye ne-MFPP zizinto ezimbini eziqhelekileyo zeplastiki.I-PP ineempawu zokumelana nobushushu, ukuxhathisa ukubola kweekhemikhali kunye noxinzelelo oluphantsi, kwaye i-MFPP iguqule i-PP kule siseko ukuze ifumane amandla angcono, ukuqina kunye nokuchasana kwempembelelo.Ezi zixhobo zimbini zidlala indima ebalulekileyo kwiinkalo ezahlukeneyo zesicelo, ukuzisa lula kunye nophuhliso kubomi bethu kunye neenkalo ezahlukeneyo zoshishino.
