Chifukwa Chiyani Muzigwiritsa Ntchito Biodegradable Plastic Material?

Chifukwa chiyani mumagwiritsa ntchito mapulasitiki owonongeka?

Pulasitiki ndi chinthu chofunikira kwambiri. Ndi chitukuko chofulumira chachuma ndi anthu komanso kuwonekera kwa mafakitale ambiri atsopano monga malonda a e-commerce, kutumiza mwachangu ndi kutenga, kugwiritsa ntchito zinthu zapulasitiki kukukwera kwambiri.
Pulasitiki sikuti imangobweretsa chisangalalo chachikulu m'moyo wa anthu, komanso imayambitsa "kuipitsa koyera", komwe kumawononga kwambiri chilengedwe komanso thanzi la anthu.
China yaika momveka bwino cholinga chomanga China yokongola, ndipo kuwongolera "kuipitsa koyera" ndikofunikira kuwongolera chilengedwe komanso kumanga China yokongola.

Kodi mapulasitiki a biodegradable ndi chiyani?

Mapulasitiki owonongeka ndi mapulasitiki omwe amadetsedwa ndi zochita za tizilombo tating'onoting'ono, monga dothi, dothi lamchenga, malo amadzi abwino, malo amadzi am'nyanja ndi zinthu zina monga composting kapena anaerobic digestion, ndipo pamapeto pake amawonongeka kukhala carbon dioxide (CO2) kapena / ndi methane (CH4), madzi (H2O) ndi mineralized mchere mchere wa zinthu zawo, komanso zotsalira zazomera zatsopano (monga tizilombo akufa, etc.).

Kodi magulu apulasitiki owonongeka ndi ati?

Malinga ndi Standard Guide for Classification and lebeling of pulasitiki zowonongeka zokonzedwa ndi China Federation of Light Industry, mapulasitiki owonongeka amakhala ndi machitidwe owononga m'nthaka, kompositi, nyanja, madzi abwino (mitsinje, mitsinje, nyanja) ndi malo ena.
Malinga ndi nyengo zosiyanasiyana zachilengedwe, mapulasitiki owonongeka amatha kugawidwa mu:
Mapulasitiki owonongeka a nthaka, composting mapulasitiki owonongeka, mapulasitiki owonongeka a madzi abwino, sludge anaerobic digestion mapulasitiki owonongeka, mapulasitiki apamwamba olimba a anaerobic digestion.

Kodi pali kusiyana kotani pakati pa mapulasitiki owonongeka ndi mapulasitiki wamba (osawonongeka)?

Mapulasitiki achikhalidwe amapangidwa makamaka ndi polystyrene, polypropylene, polyvinyl chloride ndi mankhwala ena a polima okhala ndi zolemera zama cell mazana masauzande komanso mawonekedwe okhazikika amankhwala, omwe ndi ovuta kunyozedwa ndi tizilombo tating'onoting'ono.
Zimatenga zaka 200 ndi zaka 400 kuti mapulasitiki achikhalidwe awonongeke m'chilengedwe, choncho n'zosavuta kuwononga chilengedwe potaya mapulasitiki achikhalidwe mwakufuna kwake.
Mapulasitiki osawonongeka ndi osiyana kwambiri ndi mapulasitiki achikhalidwe pakupanga mankhwala. maunyolo awo akuluakulu a polima ali ndi zomangira zambiri za ester, zomwe zimatha kugayidwa ndikugwiritsidwa ntchito ndi tizilombo tating'onoting'ono, ndipo potsirizira pake zimawonongeka kukhala mamolekyu ang'onoang'ono, omwe sangawononge kuwonongeka kwa chilengedwe.

Kodi "matumba apulasitiki ogwirizana ndi chilengedwe" omwe amapezeka pamsika amatha kuwonongeka?

Malinga ndi zofunikira zolembera za GB/T 38082-2019 "matumba ogula apulasitiki owonongeka", malinga ndi ntchito zosiyanasiyana zamatumba ogula, matumba ogulira ayenera kulembedwa momveka bwino kuti "matumba ogula apulasitiki okhudzana ndi chakudya" kapena "osagwirizana ndi chakudya mwachindunji. matumba ogula apulasitiki owonongeka”. Palibe chizindikiro cha "chikwama chapulasitiki chogwirizana ndi chilengedwe".
Matumba apulasitiki oteteza zachilengedwe pamsika ndi matsenga ochulukirapo opangidwa ndi mabizinesi m'dzina lachitetezo cha chilengedwe. Chonde tsegulani maso anu ndikusankha mosamala.
