Nguva pfupi yadarika, mutori wenhau akadzidza kubva kuChina Paper Association, maererano neChina Paper Association gore rega rega rekudzokorora basa kuronga, sangano rakapedza "hapana kapu yepurasitiki yepepa (kusanganisira isina purasitiki.biodegradable mapepa makapu)” group standard draft, ikozvino kuti nzanga ikumbire pfungwa.
Chiicompostable mapepa makapuhakuna kapu yepurasitiki yepepa here?Ndeupi musiyano pakati pazvo uye apersonalized paper cups?
Vatengi vazhinji vangasaziva kuti kapu dzavo dzemapepa dzinoraswa dzinoita kunge dzine hushamwari hwakatipoteredza, asi ndedzechikamu chisingadzokerikezve muchikamu chemarara.
"Makapu emapepa anoganhurirwa nechigadzirwa chebepa hachina hunhu hwemvura, kuitira kudzivirira kubuda kwemvura, firimu repurasitiki re polyethylene (PE) rakavharwa richawedzerwa kumakapu emapepa." Sekureva kwebhizinesi rekurongedza epurasitiki muHaikou, Hainan, iyo inopisa. mukombe wokunwira uchaputirwa mumukombe, uye chinwiwa chinotonhora chichaputirwa mukati nokunze kwomukombe.Hazvisi nyore kuparadzanisa kubva pamapepa mukugadzirisa zvakare, saka inoparadzaniswa kuva marara asingadzokizve.
Zvinonzwisiswa kuti kubva 1 Zvita, Hainan yakazara "mapurasitiki ekurambidza", akaverengerwa mudunhu reHainan akarambidzwa kugadzirwa uye kutengesa kushandiswa kwezvinhu zvinoraswa zvisiri biodegradable epurasitiki zvigadzirwa runyorwa (yekutanga batch) yezvigadzirwa zvepurasitiki icharambidza kugadzirwa nekutengesa, kambani. tsvakiridzo nebudiriro inogadzirwa nemvura inonamira panzvimbo pechinyakare kapu yekapu polyethylene yekupotera isina epurasitiki kapu yepepa, ziva iyo biodegradation yese.
Kunyangwe kapu yepurasitiki yepepa inogadzirwa nebhizinesi inokodzera ndiyo chiyero.Kunyorwa kwepasina kapu yepurasitiki yepepa (kusanganisira isina epurasitiki pepa mukombe pepa) inotaura kuti " base bepa makapu inofanira kusangana nezvinodiwa zveQB / T 4032. Mafuta machena achasangana nezvinodiwa zveGB 1886.215.Iyo inki nenamira ichaenderana nezvinodiwa.Iwo ekuwedzera anoshandiswa mumakapu emapepa, mafuta machena, ingi, anonamira uye emvura-based coatings anofanirwa kusangana nezvinodiwa zveGB 9685. "
Zvinoenderana nenhanganyaya, yakajairwa kapu yemapepa kapu nekuti ine polyethylene, isingagone kudzokororwa, kwete rudzi rwekuchengetedzwa kwezvakatipoteredza zvinodiwa zvezuva nezuva.Kunyangwe PLA yakavharwa mapepa emakapu anogona kuve akazara biodegradable, iyo yakakwira mutengo wemidziyo inotungamira kumutengo wepamusoro wezvigadzirwa zvakapedzwa.Nekusimudzirwa kwe "kurambidzwa kwehombodo dzepurasitiki", hapana makapu emapepa epurasitiki akazovapo.
Zvinonzwisiswa kuti "plastic ban" ine polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinyl chloride-vinyl acetate copolymer, polyethylene terephthalate uye zvimwe zvisiri biodegradable polymer zvinhu zve-single-kushandisa zvigadzirwa zvepurasitiki.
“Kumugadziri wemikombe yemapepa, kana akawana chinhu chakachipa chinoenderana nezvinodiwa zvekapu yemapepa uye isiri imwe yezvinhu zvitanhatu zvisingaore, ipapo kapu yake yemapepa inogona kunzi makapu epurasitiki oiswa pamusika. .” Nyanzvi dzakaudza vatori venhau.
Pamusoro pezvo, inogona kuunzwa zvichienderana nekuti iyo yekupfekedza inokanganisa haizove kapu yepurasitiki yepepa yakakamurwa zvikamu zviviri, zvinoti "kupfekedza kapu yepepa isingaparare" uye "kuputira kapu yepepa inoora".Kune yekare, chero bedzi zvigadzirwa zvekuputira zvisingabatanidzwi mune yazvino runyorwa rwezvinhu zvisingagadzirisiki, zvinogona kuramba zvichiunzwa zviri pamutemo kumusika.
Sezvo tekinoroji iri kufambira mberi, tarisiro ndeyekuti zvinhu zvakachipa zvinoodza biodegradable zvichawanikwa, vanhu vakadaro.
