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 zePP 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, izizalisi okanye ezinye iimodyuli ezitshintsha isakhiwo sepolymer kunye nokubunjwa ukuze zinike iimpawu 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 kubomi bemihla 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 zemoto, iicasing zemveliso ye-elektroniki, izinto zokwakha, njl.

Ekugqibeleni, 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 kwesi 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.
