Kodi chilengedwe cha HPMC chikuyerekeza bwanji ndi pulasitiki?

Hydroxypropyl methylcellulose (HPMC) ndi polima yosungunuka m'madzi yomwe nthawi zambiri imadziwika kuti ndi zomangira zosunga zachilengedwe.

Biodegradability: HPMC ili ndi biodegradability yabwino m'chilengedwe, zomwe zikutanthauza kuti imatha kuwola ndi tizilombo tating'onoting'ono m'mikhalidwe ina ndipo pamapeto pake imasandulika kukhala zinthu zosavulaza zachilengedwe. Mosiyana ndi zimenezi, mapulasitiki achikhalidwe monga polyethylene ndi polypropylene ndi ovuta kuwononga ndi kukhalabe m'chilengedwe kwa nthawi yaitali, zomwe zimayambitsa "kuipitsa koyera."

Kukhudza zachilengedwe: Momwe pulasitiki amapangidwira, kugwiritsidwa ntchito ndi kutayidwa ndikuwononga chilengedwe, kuyika thanzi la anthu pachiwopsezo komanso kusokoneza nyengo. Kuwonongeka kwa pulasitiki pa chilengedwe kumaphatikizapo kuipitsa nthaka, kuipitsa madzi, kuwononga nyama zakuthengo ndi zomera, ndi zina zotero. HPMC, kumbali ina, ili ndi mphamvu yochepa kwambiri pa chilengedwe chifukwa cha kuwonongeka kwake.

Mpweya wa Mpweya: Kafukufuku wa gulu la Academician Hou Li'an akuwonetsa kuti mpweya wotulutsa mapulasitiki osawonongeka (monga HPMC) pa nthawi yonse ya moyo ndi pafupifupi 13.53% - 62.19% yotsika kuposa zinthu zamapulasitiki zachikhalidwe, zomwe zikuwonetsa kuthekera kwakukulu kochepetsera mpweya.

Kuwonongeka kwa Microplastic: Kupita patsogolo kwa kafukufuku wokhudza tizilombo tating'onoting'ono m'chilengedwe kumasonyeza kuti kukhudzidwa kwa tinthu tating'onoting'ono ta pulasitiki pa nthaka, matope, ndi madzi opanda mchere kungakhale ndi zotsatira zoipa kwa nthawi yaitali pa zachilengedwezi. Tinthu tating'ono ta pulasitiki titha kukhala owopsa kumtunda kuwirikiza ka 4 mpaka 23 kuposa kunyanja. Chifukwa biodegradability ake, HPMC si kulenga kupitiriza microplastic kuipitsidwa mavuto.

Kuopsa kwa chilengedwe: Mavuto azachuma omwe amabwera chifukwa cha kuwonongeka kwa pulasitiki ndi ofunika kwambiri, ndi ndalama zomwe zimagwirizanitsidwa ndi kuyeretsa zinyalala za pulasitiki, kukhazikitsa njira zoyendetsera zinyalala, ndi kuthana ndi zotsatira za chilengedwe ndi thanzi zomwe zimabwera chifukwa cha kuwonongeka kwa pulasitiki zomwe zikubweretsa mavuto azachuma m'madera ndi maboma. Monga zinthu zowonongeka, HPMC ili ndi zoopsa zochepa zachilengedwe.

Kuwunika kwachilengedwe: Pakuwunika kwachilengedwe, kupanga ndi kugwiritsa ntchito kwa HPMC kumakhudza pang'ono mlengalenga, madzi ndi nthaka, komanso njira zoyeretsera zomwe zimatengedwa panthawi yopanga zimatha kuchepetsa kukhudzidwa kwa chilengedwe.

Monga zinthu zokonda zachilengedwe, HPMC ili ndi zabwino zodziwikiratu kuposa mapulasitiki achikhalidwe malinga ndi momwe chilengedwe chimakhudzira, makamaka pakuwonongeka kwachilengedwe, kutulutsa mpweya wa kaboni ndi kuipitsidwa kwa microplastic. Komabe, kukhudzidwa kwa chilengedwe kwa HPMC kumafunikanso kuwunikiridwa mozama kutengera zinthu monga momwe amapangira, kagwiritsidwe ntchito ndi kutaya kwake.
