Kodi PP ndi chiyani?
PP ndifupifupi ku Polypropylene, polimando wa thermoplastic yopangidwa kuchokera ku polymesiyation ya Probylene Monomer. Monga zopangira pulasitiki zofunika kwambiri, ma pp ali ndi ntchito zingapo pamoyo watsiku ndi tsiku komanso kupanga mafakitale. Munkhaniyi, tikambirana mwatsatanetsatane zomwe ma pp zinthu zili, komanso mawonekedwe ake, amagwiritsa ntchito ndi zabwino.
Makhalidwe oyamba a ma pp
Zinthu za PP zili ndi zinthu zabwino komanso zamankhwala. Kuchulukitsa kwake kumakhala kochepa, kokha ndi 0,9 g / cm³, ndiye kachulukidwe kakang'ono kwambiri kwa ma plastics wamba, motero kumakhalanso bwino kwambiri, kumatha kugwiritsidwa ntchito mobwerezabwereza , ndipo ma acid ambiri, alkalis ndi oundana amasungunuka amakhala ndi kukana bwino. Chifukwa cha zabwino izi, za PP zinthu zakhala zosankha bwino pankhani zambiri.
Gulu ndi kusintha kwa zinthu za ma PP
Zida za PP zitha kulembedwa m'magulu awiri, ma polypropylene ndi Cuolymer Polyproplene, kutengera kapangidwe kake kalengedwe ndi katundu. Homepolymer Polypropylene ali ndi mphamvu kwambiri komanso mphamvu, ndikupangitsa kuti zikhale zoyenera zolimbitsa thupi, ndipo nthawi zambiri zimagwiritsidwa ntchito pokana kutsutsana.P ikhoza kugwiritsidwanso ntchito kusinthidwa powonjezera ulusi wamagalasi, mafilimu, kapena rader oterera kuti azitha kusintha zinthu zake mwakuthupi komanso kuthana ndi zosowa zamitundu yosiyanasiyana. PP imatha kusinthidwa ndikuwonjezera ulusi wagalasi kapena mafilimu ogulitsa mchere kuti asinthe zinthu zake zakuthupi komanso kukana kutentha kuti mukwaniritse ntchito zambiri.
Madera a pp
Zipangizo za PP zimapezeka paliponse m'moyo, ndipo zopempha zawo zimaphimba minda yambiri, kuchokera pazopangira ndi zinthu zapakhomo ndi zida zamagetsi ndi zida zamankhwala. Pamunda wa ma CP, mabungwe a PP amagwiritsidwa ntchito kwambiri popanga zakudya zokhala ndi zakudya, ma botolo a boti, mafilimu ndi zinthu zina, zomwe zimakondana, zomwe zimakhala zopanda pake komanso zokhala ndi zomwe zimachitika. Pazinthu zapakhomo, ma pp zinthu zambiri zimagwiritsidwa ntchito popanga mabokosi osungira, kuchapa, mipando ndi zina zotero. Chifukwa cha kutentha kwake ndi kukana kwa mankhwala, ma pp amagwiritsidwanso ntchito makampani ogulitsa, ma boashboard ndi milandu yowonongeka, monga ma syrime osweka, zida zopangira mabotolo.
Zachilengedwe komanso zokhazikika
M'zaka zaposachedwa, kudziwitsa chilengedwe kwachuluka, zinthu za PP zalandira chidwi kwambiri chifukwa chobwezeretsanso zachilengedwe komanso kutsika kwa chilengedwe. Zida za PP zitha kung'ambika mwa kubwezeretsanso pambuyo potaya, kuchepetsa kuipitsidwa kwa chilengedwe. Ngakhale ma pp zinthu sizabwino, mphamvu zake zachilengedwe zimatha kuchepetsedwa moyenera poyang'anira zinyalala zasayansi ndikubwezeretsanso. Chifukwa chake, ma pp zinthu zimawerengedwa kuti ndi chilengedwe komanso chopanda pake.
Chidule
Zinthu za PP ndizothandiza kwambiri pulasitiki ndi mapulogalamu osiyanasiyana. Kuchulukitsa kwake kochepa, kukana kutentha, kukana kwa mankhwala ndi kubwezeretsanso kumapangitsa kukhala chimodzi mwazinthu zofunika kuzigwiritsa ntchito zamakono komanso moyo watsiku ndi tsiku. Mwa kumvetsetsa zomwe ma pp m'zinthu ndi madera ake a ntchito, mutha kugwiritsa ntchito bwino ntchito izi kuti mupereke njira yodalirika yopangira kapangidwe ka mitundu yonse ya zinthu.
