Izi zimakupatsani kumvetsetsa kwakukulu kwa matumba osungiramo zinthu omwe amatha kuwola!
Pamene mayiko ambiri akuletsa matumba apulasitiki, matumba ovunda akugwiritsidwa ntchito m'mafakitale ambiri. Kuteteza chilengedwe ndi chizolowezi chosapeŵeka. Kodi pali magwero aliwonse omwe amalimbikitsa kugwiritsa ntchito matumba apulasitiki ovunda? Ndi zinthu ziti zomwe matumba apulasitiki ovunda angagwiritsidwe ntchito? Ndikukhulupirira kuti izi ndi zomwe makasitomala ambiri amalamula zofunikira pa matumba apulasitiki ovunda mokwanira akufuna kudziwa. Lero, OK Kupanga ma paketi a matumba apulasitiki ovunda
1. Kodi phukusi lotha kuwola ndi chiyani?
Thumba la pulasitiki lotha kuwonongeka ndi mtundu wa thumba la pulasitiki lomwe lingawononge madzi, carbon dioxide ndi mamolekyu ena ang'onoang'ono. Gwero lalikulu la zinthu zotha kuwonongeka izi ndi polylactic acid (PLA), yomwe imachokera ku chimanga ndi chinangwa. Planet (PLA) ndi mtundu watsopano wa zinthu zopangidwa ndi zamoyo komanso zinthu zotha kuwonongekanso. Pambuyo pophika shuga ndi mitundu ina kuti apange lactic acid yoyera kwambiri, poly (lactic acid) yokhala ndi kulemera kwa mamolekyulu ena idapangidwa pogwiritsa ntchito njira yopangira mankhwala, kenako shuga idapezeka pogwiritsa ntchito saccharification. Chogulitsachi chili ndi kuwonongeka kwabwino kwachilengedwe ndipo chimatha kuwonongeka kwathunthu ndi tizilombo toyambitsa matenda achilengedwe pambuyo pogwiritsidwa ntchito kuti apange carbon dioxide ndi madzi, zomwe sizingaipitse chilengedwe pambuyo pogwiritsidwa ntchito. Ndi chothandiza kwambiri kuteteza chilengedwe ndipo chimaonedwa ngati chinthu choteteza chilengedwe.
Pakadali pano, zinthu zazikulu zamoyo zomwe zimapezeka m'matumba apulasitiki owonongeka zimapangidwa ndi PLA + PBAT, yomwe imatha kusungunuka kwathunthu kukhala madzi ndi carbon dioxide m'miyezi 3-6 ngati ikugwiritsidwa ntchito popanga manyowa (madigiri 60-70). Palibe kuipitsidwa kwa chilengedwe. Nchifukwa chiyani PBAT iyenera kuwonjezeredwa? PBAT ndi copolymer ya adipic acid, 1, 4-butanediol ndi terephthalic acid, yomwe ndi polymer ya aliphatic ndi aromatic yopangidwa ndi mankhwala. PBAT ili ndi kusinthasintha kwabwino kwambiri ndipo ingagwiritsidwe ntchito potulutsa filimu, kupanga blow molding, extrusion coating ndi njira zina zopangira. Kusakaniza kwa PLA ndi PBAT kwapangidwa kuti kuwonjezere kulimba, kuwonongeka kwa biogradable ndi kapangidwe ka PLA.
2. Kodi opanga matumba otha kuwola omwe ali ndi mbiri yabwino ali kuti?
Pankhani ya matumba apulasitiki ovunda, yapanga makina apadera opukutira filimu, makina osindikizira, makina odulira matumba, granulator yobwezeretsanso zinyalala ndi mizere yosiyanasiyana yopangira matumba apulasitiki ovunda. Zogulitsa zimaphimba matumba a vest, matumba a zinyalala, matumba a m'manja, matumba a zovala, matumba a hardware, matumba odzola, matumba a chakudya, matumba a mutu wa khadi, matumba a kraft paper /PLA composite, ndi zina zotero, khalidwe lokhazikika, kupanga bwino kwambiri, kusindikiza kwabwino, kusanyowa, kusabowoka, kusapha poizoni, kutseka bwino, kutambasula bwino, kapangidwe kabwino, kuteteza chilengedwe.
Ma CD OK, omwe amatsatira lingaliro la kuteteza chilengedwe, amadzipereka ku chitukuko chokhazikika cha chilengedwe, amapangidwa bwino ndipo ndi oyenera makampani opanga ma CD ndi zinthu zophikira, ali ndi chidziwitso chochuluka mumakampani opanga ma CD ndipo amayankha magulu a zinyalala, amalimbikitsa kugwiritsanso ntchito zinthu, komanso amapanga mwachangu zinthu zophikira zonse zomwe zimawola.
3. Ndi zinthu ziti zomwe matumba ovunda angagwiritsidwe ntchito?
Matumba apulasitiki ovunda amagwiritsidwa ntchito kwambiri mu malaya, kuluka, zovala, zovala, nsalu, chakudya, zida zamagetsi, zamagetsi, zodzoladzola ndi mafakitale ena. Matumba apulasitiki ovunda ali ndi mapangidwe ambiri otsekera, monga fupa lomatira, zipu, tepi, ndi zina zotero, ndipo matumba apulasitiki ovunda amaphatikizidwa ndi pepala, lomwe limatha kupindika chiwalo chapansi. Tsopano, matumba apulasitiki ovunda akulowa m'mbali zonse za moyo, ndipo pali mitundu yosiyanasiyana; M'tsogolomu, matumba apulasitiki ovunda adzakhala chinthu chenicheni cha makampani opangira ma CD.
