Pp pepala, kapena pepala la polypropylene, ndi pepala la mafuta a thermoplasting enings lopangidwa makamaka kuchokera ku polypropylene ulen. Chifukwa cha kuchuluka kwake kwabwino kwambiri, kukhazikika kwamankhwala, komanso kusinthika kwa kukonza, kuphatikiza kwa mafakitale kosiyanasiyana, kuphatikizapo kupanga mafakitale, zokongoletsera zomangamanga, ndi zida zoteteza zachilengedwe. Nkhaniyi ifotokoza za zigawo za PP pepala, malongosoledwe ake oyambira, komanso zochitika zamtsogolo.
Magawo oyamba a ma pp
Mapepala a PP amapereka kachulukidwe kakang'ono (pafupifupi 0.9-0.91 g / cm³), mphamvu yayikulu, komanso kukana kwamphamvu kwamphamvu. Mfundo yake yosungunuka imakhala pakati pa digiri ya 160 ndi digiri ya 170, kusunga malo okhazikika pamtundu wambiri komanso oyenera kugwirira ntchito kuchokera -20 digiri mpaka 120 digiri. PP pepala limawonetsanso bwino magetsi ambiri, kukana kwamphamvu, komanso kuvala kukana. Kuwonekera kwake kumapangitsa kuti ndikosavuta kupanga ndi kusintha, kulola kudula, kuwotcherera, ndi kubowola.
Kuchokera pamalingaliro azachilengedwe, mapepala a PP ndi okhawo. Chifukwa chake, amapereka zabwino zamapulogalamu okhudza chakudya kapena zotengera zamankhwala ndi ma pichelines. Kuphatikiza apo, mapepala a ma pp amakonzedwanso, kukwaniritsa zofunikira zotukuka zamakono zamakono.
Mapulogalamu Akuluakulu a PP
1. Kupanga mafakitale
Mu mankhwala, mafuta, ndi mafakitale opangira mankhwala, mapepala a ma pp amagwiritsidwa ntchito popanga magazini, zingwe zosungira, mpweya wabwino, ndi zida zosewerera. Awo otsutsana ndi aciyer acid ndi alkali amawathandiza kuthana ndi makanema osiyanasiyana, kutumiza zida zamoyo. Mapepala a ma PP amagwiritsidwanso ntchito kwambiri popanga makina, monganso kungobwezeretsa mbale ndikuvala mizere, kuti akweze kukhazikika kwa zida.
2. Ntchito ndi zokongoletsera
Chifukwa cha kukhazikitsa kwawo kopepuka komanso kosavuta, ma sp amagwiritsidwa ntchito popanga zomangamanga ngati zida zomangamanga, kugawa khoma lamatanda, ndi ma ponels. Pamwamba pake pamwamba amatha kuvotera kapena kusindikiza kuti mukwaniritse zofunika kwambiri. Mapepala a PP amaperekanso mawu abwino komanso kutentha katundu, ndikuwapangitsa kukhala oyenera malo okhala ndi zomangamanga ndi zofunikira zapadera.
3. Kuteteza kwa chilengedwe ndi malo apagulu
Muzolinga za chilengedwe monga chithandizo cha chilengedwe komanso kutaya zinyalala, mapepala a ma pp amagwiritsidwa ntchito popanga ma cell osagwirizana, zophimba, ndi akasinja osungira madzi. Kukana kwawo kwamphamvu kumawalola kuti apirire nthawi yayitali {{2}, mawu akunja osakalamba. Ma sp a PP amagwiritsidwanso ntchito kwambiri m'magawo azachipatala, monga chipatala m'chipinda chosatsutsika m'chipindacho ndi ma couctoops oyang'anira, chifukwa cha zinthu zawo zosavuta kwa antikocteal.
Zochita zamtsogolo za mapepala a PP
Kuthamangira kwa Science Science, magwiridwe antchito a ma PP akukonzekera mosalekeza. Mwachitsanzo, Copsolymerization, kusintha, komanso kukonzekera kudzaza kumagwiritsidwa ntchito kuwonjezera kuungula kwawo, kukana kutentha, ndi kukana UV. M'tsogolo, mapepala a PP adzakulanso pamayendedwe otsatirawa:
1. Masewera olimbitsa thupi: kukulitsa momwe mapepala a ma PP kudzera mwa Nanocomwoposites ndi kuyendetsa bwino kuti akwaniritse zosowa zothandizira mafakitale.
2.gree ndi ochezeka kwambiri: Pangani biodegrad kapena bio {{1}
3.
Monga pepala lopanga bwino kwambiri, pepala la PP lakhala chinthu chofunikira kwambiri pakugwiritsa ntchito mafakitale amakono ndi ziyembekezo zabwino kwambiri. Ndi kupita patsogolo kwaukadaulo, kugwiritsa ntchito kapepala kwa PP kungakulitseninso, ndipo kumathandizanso kwambiri pakulimbikitsa kukwera mafakitale ndi chilengedwe. M'tsogolomu, makampani ogulitsa ma pp amafunika kupitilizabe kupanga zosintha kuti zisinthe zofuna za msika ndikupeza ntchito yabwino komanso yokhazikika.
