Kodi kusiyana pakati pa zinthu zopangidwa ndi PP ndi MFPP ndi kotani?

PP (polypropylene) ndi chinthu chofala chomwe chimagwiritsidwa ntchito popanga pulasitiki chomwe chimatha kupirira kutentha, mankhwala oletsa komanso chofooka kwambiri. MFPP (modified polypropylene) ndi chinthu chosinthidwa cha polypropylene chomwe chili ndi mphamvu komanso kulimba kwamphamvu. Pazinthu ziwirizi, nkhaniyi ipereka chiyambi chodziwika bwino cha sayansi pankhani ya magwero a zinthu zopangira, njira zokonzekera, makhalidwe, ndi malo ogwiritsira ntchito.

1. Magwero a zinthu zopangiraPP ndi MFPPZipangizo zopangira za PP zimakonzedwa pogwiritsa ntchito polymerizing propylene mu mafuta. Propylene ndi chinthu cha petrochemical chomwe chimapezeka makamaka kudzera mu njira yosweka m'mafakitale oyeretsera. Polypropylene yosinthidwa MFPP imawongolera magwiridwe ake powonjezera ma modifier ku PP wamba. Ma modifier awa akhoza kukhala zowonjezera, zodzaza kapena ma modifier ena omwe amasintha kapangidwe ka polima ndi kapangidwe kake kuti apatse mawonekedwe abwino komanso achilengedwe.

2. Njira yokonzekera PP ndi MFPP Kukonzekera kwa PP kumachitika makamaka kudzera mu polymerization reaction. Propylene monomer imapangidwa kukhala polymer mu unyolo wa polymer wautali winawake kudzera mu ntchito ya catalyst. Njirayi imatha kuchitika mosalekeza kapena mosasinthasintha, kutentha kwambiri komanso kupsinjika. Kukonzekera kwa MFPP kumafuna kusakaniza modifier ndi PP. Kudzera mu kusakaniza kosungunuka kapena kusakaniza yankho, modifier imafalikira mofanana mu PP matrix, potero kukonza mawonekedwe a PP.

3. Makhalidwe a PP ndi MFPP PP ili ndi kukana kutentha bwino komanso kukhazikika kwa mankhwala. Ndi chinthu cholimbapulasitiki yowonekera bwino ndi kuuma ndi kulimba kwina. Komabe, mphamvu ndi kulimba kwa PP wamba ndizochepa, zomwe zimapangitsa kuti zinthu zosinthidwa monga MFPP ziyambe kugwiritsidwa ntchito. MFPP imawonjezera zinthu zina zosinthira ku PP kuti MFPP ikhale ndi mphamvu, kulimba komanso kukana kukhudza bwino. Zosintha zimathanso kusintha kutentha, mphamvu zamagetsi komanso kukana nyengo kwa MFPP.

4. Magawo ogwiritsira ntchito a PP ndi MFPP PP imagwiritsidwa ntchito kwambiri ndipo imagwiritsidwa ntchito kwambiri m'mabotolo, mipando, zida zamagetsi ndi zinthu zina pamoyo watsiku ndi tsiku. Chifukwa cha kukana kutentha ndi kukana mankhwala, PP imagwiritsidwanso ntchito m'mapaipi, mabotolo, ma valve ndi zida zina mumakampani opanga mankhwala. MFPP nthawi zambiri imagwiritsidwa ntchito m'mabotolo omwe amafuna mphamvu zambiri komanso kulimba, monga zida zamagalimoto, zikwama zamagetsi, zipangizo zomangira, ndi zina zotero.

Pomaliza, PP ndi MFPP ndi zinthu ziwiri zofananazipangizo zapulasitiki. PP ili ndi makhalidwe monga kukana kutentha, kukana dzimbiri ndi mankhwala komanso kusakhala ndi mphamvu zambiri, ndipo MFPP yasintha PP pamaziko awa kuti ikhale ndi mphamvu, kulimba komanso kukana kukhudza. Zipangizo ziwirizi zimagwira ntchito yofunika kwambiri m'magawo osiyanasiyana ogwiritsira ntchito, zomwe zimapangitsa kuti zinthu zikhale zosavuta komanso zopanga chitukuko m'miyoyo yathu komanso m'magawo osiyanasiyana a mafakitale.
