Posachedwapa, mtolankhaniyo adaphunzira kuchokera ku China Paper Association, malinga ndi bungwe la China Paper Association pachaka lokonzanso ntchito, bungweli lamaliza "kapu yamapepala apulasitiki (kuphatikiza palibe pulasitiki.makapu a pepala osawonongeka)” gulu lokonzekera, tsopano kuti anthu apeze malingaliro.
Chanicompostable mapepala makapupalibe kapu yamapepala apulasitiki?Kodi pali kusiyana kotani pakati pa izo ndi amakapu apepala amunthu payekha?
Ogula ambiri sangadziwe kuti makapu awo amapepala omwe amatha kutaya nthawi zonse amawoneka kuti ndi okonda zachilengedwe, koma ali m'gulu lomwe silingathe kubwezeretsedwanso m'magulu a zinyalala.
"Makapu amapepala amachepetsedwa ndi zomwe zimapangidwa ndi pepala sizomwe zimatetezedwa ndi madzi, pofuna kuteteza madzi kuti asalowe, filimu ya pulasitiki ya polyethylene (PE) idzawonjezeredwa ku makapu a mapepala." Chikho chakumwa chidzakwiriridwa m'chikho, ndipo chakumwa chozizira chidzakwiriridwa mkati ndi kunja kwa chikho.Sikophweka kupatukana ndi pepala mu ndondomeko yobwezeretsanso, kotero imagawidwa mu zinyalala zosasinthika.
Zikumveka kuti kuyambira Disembala 1, "pulasitiki yoletsa" ya Hainan, idaphatikizidwa m'chigawo cha Hainan, yoletsa kupanga ndi kugulitsa kugwiritsa ntchito mndandanda wazinthu zapulasitiki zosawonongeka (gulu loyamba) lazinthu zapulasitiki zidzaletsa kupanga ndi kugulitsa, kampaniyo. kafukufuku ndi chitukuko chopangidwa ndi zokutira madzi m'malo mwa mwambo pepala chikho polyethylene zokutira popanda pulasitiki pepala kapu, kuzindikira biodegradation lonse.
Kaya kapu ya pulasitiki yopangidwa ndi bizinesi ndiyoyenera ndiye muyezo.Kukonzekera kwa kapu ya pepala la pulasitiki (kuphatikizapo palibe pepala la pepala la pulasitiki) likunena kuti " makapu a mapepala apansi ayenera kukwaniritsa zofunikira za QB / T 4032. Mafuta oyera adzakwaniritsa zofunikira za GB 1886.215.Inki ndi zomatira ziyenera kutsatira miyezo yoyenera.Zowonjezera zomwe zimagwiritsidwa ntchito m'makapu amapepala, mafuta oyera, inki, zomatira ndi zokutira zokhala ndi madzi ziyenera kukwaniritsa zofunikira za GB 9685. "
Malinga ndi mawu oyamba, wamba disposable pepala chikho chifukwa muli polyethylene, kwenikweni osati recyclable, osati mtundu wa chitetezo zachilengedwe zofunika tsiku ndi tsiku.Ngakhale makapu a pepala okutidwa ndi PLA amatha kuwonongeka kwathunthu, kukwera mtengo kwazinthu zopangira kumabweretsa kukwera mtengo kwazinthu zomalizidwa.Polimbikitsa "kuletsa matumba apulasitiki", palibe makapu apulasitiki omwe adakhalapo.
Zimamveka kuti "pulasitiki yoletsa" imakhala ndi polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinyl chloride-vinyl acetate copolymer, polyethylene terephthalate ndi zinthu zina zopanda biodegradable polima zopangidwa ndi pulasitiki imodzi yokha.
"Kwa wopanga chikho cha mapepala, ngati angapeze zinthu zotsika mtengo zomwe zimakwaniritsa zofunikira za kapu ya pepala ndipo si imodzi mwa zipangizo zisanu ndi chimodzi zosawonongeka, ndiye kuti chikho chake cha pepala chikhoza kutchedwa makapu a mapepala apulasitiki ndikuyika pamsika. ”Akatswiri adauza atolankhani.
Komanso, akhoza anayambitsa malinga ❖ kuyanika ndi degradable adzakhala palibe pulasitiki pepala chikho pafupifupi m'magulu awiri, ❖ kuyanika sanali degradable pepala chikho "ndi" ❖ kuyanika degradable pepala chikho ".Zakale, malinga ngati zopangira zokutira sizikuphatikizidwa pamndandanda wamakono wazinthu zosawonongeka, zimatha kubweretsedwa pamsika mwalamulo.
Pamene zipangizo zamakono zikupita patsogolo, chiyembekezo n’chakuti zinthu zotsika mtengo kwambiri zowola ndi zinthu zachilengedwe zizipezeka, anthu anatero.
