Kodi pali kusiyana kotani pakati pa PP ndi MFPP?

PP (polypropylene) ndi pulasitiki wamba yokhala ndi kukana bwino kwa kutentha, kukana kwa mankhwala komanso kutsika kochepa. MFPP (modified polypropylene) ndi polypropylene yosinthidwa yokhala ndi mphamvu zolimba komanso zolimba. Pazinthu ziwirizi, nkhaniyi ipereka chidziwitso chodziwika bwino cha sayansi potengera magwero azinthu zopangira, njira zokonzekera, mawonekedwe, ndi magawo ogwiritsira ntchito.

1. Zopangira gwero la PP ndi MFPP Zopangira za PP zimakonzedwa ndi polymerizing propylene mu petroleum. Propylene ndi mankhwala a petrochemical makamaka omwe amapezeka kudzera munjira yosweka m'malo oyeretsera. Modified polypropylene MFPP imathandizira magwiridwe ake powonjezera zosintha ku PP wamba. Zosinthazi zitha kukhala zowonjezera, zodzaza kapena zosintha zina zomwe zimasintha mawonekedwe a polima ndi kapangidwe kake kuti apatse mawonekedwe abwinoko akuthupi ndi mankhwala.

2. Kukonzekera kwa PP ndi MFPP Kukonzekera kwa PP kumatheka kudzera mu polymerization reaction. Propylene monomer imapangidwa ndi polymer mu unyolo wa polima wautali winawake kudzera muzothandizira. Njirayi imatha kuchitika mosalekeza kapena pang'onopang'ono, pakutentha kwambiri komanso kupsinjika. Kukonzekera kwa MFPP kumafuna kusakaniza zosintha ndi PP. Kupyolera mu kusakaniza kosungunuka kapena kusakaniza kwa njira, chosinthiracho chimabalalitsidwa mofanana mu matrix a PP, motero kumapangitsa kuti PP ikhale yabwino.

3. Makhalidwe a PP ndi MFPP PP ali ndi kutentha kwabwino komanso kukhazikika kwa mankhwala. Ndi pulasitiki yowonekera yokhala ndi kuuma kwina kwake komanso kusasunthika. Komabe, mphamvu ndi kulimba kwa PP wamba ndizochepa, zomwe zimatsogolera kukhazikitsidwa kwa zinthu zosinthidwa monga MFPP. MFPP imawonjezera zosintha zina ku PP kupanga MFPP kukhala ndi mphamvu zabwinoko, kulimba komanso kukana kukhudzidwa. Zosintha zimathanso kusintha matenthedwe matenthedwe, mphamvu zamagetsi komanso kukana kwanyengo kwa MFPP.

4. Minda yogwiritsira ntchito PP ndi MFPP PP imagwiritsidwa ntchito kwambiri ndipo imagwiritsidwa ntchito kwambiri muzitsulo, mipando, zipangizo zamagetsi ndi zinthu zina pamoyo watsiku ndi tsiku. Chifukwa cha kukana kwake kutentha ndi kukana kwa mankhwala, PP imagwiritsidwanso ntchito mu mapaipi, zotengera, ma valve ndi zida zina mumakampani opanga mankhwala. MFPP imagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira mphamvu komanso kulimba mtima, monga zida zamagalimoto, zida zamagetsi zamagetsi, zida zomangira, ndi zina zambiri.

Pomaliza, PP ndi MFPP ndi zida ziwiri zapulasitiki zomwe wamba. PP ili ndi mikhalidwe ya kukana kutentha, kukana kwa dzimbiri kwa mankhwala ndi kachulukidwe kakang'ono, ndipo MFPP yasintha PP pamaziko awa kuti ipeze mphamvu zabwino, kulimba komanso kukana. Zida ziwirizi zimagwira ntchito yofunikira m'magawo osiyanasiyana ogwiritsira ntchito, kubweretsa kumasuka ndi chitukuko m'miyoyo yathu ndi mafakitale osiyanasiyana.
