Kodi ndi zinthu ziti zomwe mungasinthire pa tableware pakali pano? Kodi pali kusiyana kotani? Mndandanda wa zida zodziwika bwino zotayika zotayika pamsika
Pankhani yolimbikitsa chitetezo cha chilengedwe, mabizinesi ochulukirachulukira pang'onopang'ono akusintha mabokosi wamba omwe amatayidwa ndi ma tableware owonongeka kuti achepetse kuwononga chilengedwe. Palinso mitundu yochulukirachulukira ya mabokosi okonda zachilengedwe komanso owonongeka omwe akuwonekera pamsika.
Ndiye bokosi la nkhomaliro la biodegradable ndi chiyani? Kodi zigawo zikuluzikulu za bokosi la nkhomaliro lowonongeka ndi chiyani? Kodi pali kusiyana kotani pakati pa mabokosi a nkhomaliro owonongeka opangidwa ndi zinthu zosiyanasiyana?
Biodegradable tableware amatanthauza tableware kuti akhoza kukumana biochemical zimachitikira pansi zochita za tizilombo (mabakiteriya, nkhungu, algae) ndi michere mu chilengedwe, kuchititsa nkhungu kunja kwa kusintha khalidwe mkati, potsirizira pake kupanga mpweya woipa ndi madzi.
Pali mitundu iwiri ya zipangizo zomwe zimagwiritsidwa ntchito pa tableware zowonongeka: imodzi imapangidwa ndi zinthu zachilengedwe, monga mapepala, udzu, wowuma, ndi zina zotero, zomwe zimatha kuwonongeka kwathunthu, zomwe zimatchedwanso zachilengedwe; Mtundu wina umapangidwa kuchokera ku pulasitiki monga chigawo chachikulu, kuwonjezera zinthu monga wowuma ndi photosensitizers, zomwe zingawonongeke pang'ono.
Lero, tiyeni tiyang'ane pa tableware zowonongeka zowonongeka pamsika.
Chimanga wowuma zochokera tableware
Corn starch based tableware ndi bokosi lazakudya lomwe silingawonongeke pamsika wapano. Gwero lalikulu la wowuma ndi chimanga, choncho nthawi zina amatchedwa corn starch based. Komabe, bokosi lazakudya lamtunduwu ndi losakanizika ndi pulasitiki wowuma ndi mafuta amtundu wa PP, omwe amatchedwa bio zochokera kunja.
Chowuma cha chimanga chopangidwa ndi cornstarch chimapangitsa kuti zinthu zonse zakuthupi ziwonongeke chifukwa cha kuwonongeka kwa wowuma, koma PP yochokera ku petroleum ikagwa ikadali yosawonongeka. Mlingo wowonongeka ukhoza kufika 40% -80% kutengera kapangidwe ka bokosi la nkhomaliro, kotero ukhoza kuonedwa ngati bokosi la nkhomaliro, osati lowonongeka kwathunthu.
Choncho, corn starch zochokera tableware akhoza pang'ono m'malo mankhwala pulasitiki ndipo panopa mikangano m'malo pulasitiki tableware pamsika.
Zamkati zamkati zoumba tableware (zopakapaka zopangidwa ndi fiber fiber)
Pankhani ya zopangira, mabokosi a nkhomaliro opangidwa ndi zamkati amagwiritsa ntchito ulusi wa mbewu monga udzu wa tirigu ndi nzimbe ngati zopangira, osawonjezera zida zilizonse za PP. Amapangidwa kudzera m'mipangidwe yonyowa yowotchera, ndipo zowonjezera zamagulu azakudya monga zotsekemera zopanda madzi ndi mafuta zimawonjezedwa ku zamkati kuti mukwaniritse zotsatira zokhala ndi chakudya chozizira komanso chotentha.
Mabokosi a nkhomaliro owonongeka a mbewu ndi amodzi mwamabokosi omwe amagwira ntchito kwambiri pamsika wapano. Kutengera Chigawo cha Hainan, chomwe chinali choyamba kuletsa zida zapulasitiki, mwachitsanzo, Chigawo cha Hainan chaletsa kotheratu kugwiritsa ntchito, kufalitsa, kugulitsa, ndi kusunga zida zapulasitiki. Zamkati zoumba tableware mosakayikira zimakhala zolowa m'malo mwapulasitiki.
Mabokosi a nkhomaliro a nzimbe a Bagasse ndi amtundu wowonongeka, womwe ukhoza kusinthidwa kukhala zinthu zamoyo mkati mwa masiku 90 pansi pamikhalidwe ya kompositi ya mafakitale kapena m'nyumba, kubwerera ku chilengedwe. Ndizinthu zomwe zimatha kuwonongeka ndipo zili ndi zabwino zina panjira yoletsa pulasitiki.
PLA degradable tableware
PLA degradable nkhomaliro mabokosi zambiri amanena za mankhwala kuphatikiza PLA gulu mafilimu ndi zamkati kuumbidwa mankhwala mu zamkati akamaumba ndondomeko, ndicho PLA TACHIMATA mankhwala.
Filimu yamagulu a PLA imapangidwa ndikukonzedwa kuchokera ku asidi a polylactic ngati zopangira, zomwe zimatha kutenthedwa ndikuphatikizidwa pazamkati ndi zinthu zamapepala. Ndi kanema wosawonongeka kwathunthu.
Polylactic acid (PLA) ndi mtundu watsopano wa zinthu zomwe zimatha kuwonongeka kuchokera ku wowuma zochokera kuzinthu zongowonjezwdwanso za mbewu. Zopangira za starch zimapezedwa kudzera mu saccharification kuti apeze shuga, yemwe amafufuzidwa ndi mitundu ina kuti apange lactic acid yoyera kwambiri. Ndiye, ena molecular kulemera polylactic asidi ndi apanga mwa mankhwala kaphatikizidwe njira.
Mwa kuphatikiza njira yopangira lamination ndi zamkati zopangidwa ndi zinthu zopangidwa ndi zamkati, kugwiritsa ntchito mankhwala oletsa madzi ndi mafuta kumatha kupulumutsidwa, zomwe zimatha kusindikiza ma pores azinthu zopangidwa ndi zamkati. Pogwiritsira ntchito, tableware imachepetsa kupuma kwa chinthucho, zomwe zimapangitsa kuti pakhale kutsekemera kwapamwamba komanso nthawi yayitali yotchinjiriza.
