Nthawi zonse timatha kuona anthu akukonzanso mabotolo apulasitiki, koma kodi mukudziwa komwe mabotolo apulasitiki obwezerezedwansowa amapita?M'malo mwake, zinthu zambiri zapulasitiki zimatha kubwezeretsedwanso, ndipo kudzera m'njira zingapo, pulasitikiyo imatha kugwiritsidwanso ntchito ndikusinthidwa kukhala mapulasitiki atsopano kapena ntchito zina.Ndiye chimachitika ndi chiyani ndi mapulasitiki obwezeretsedwawa?Pamapeto pake, kodi pulasitiki idzabwerera m'miyoyo yathu m'njira yotani?M'nkhani ino tikambirana za pulasitiki recycling.
Pamene pulasitiki yochuluka imatengedwa kuchokera kumakona onse a anthu kupita kumalo obwezeretsanso, chinthu choyamba chomwe chiyenera kudutsa ndikuchotsa zinthu zambiri zomwe ziribe kanthu ndi pulasitiki, monga malemba, zivindikiro, ndi zina zotero. , kenaka muzisanja molingana ndi mtundu ndi mtundu wake, kenaka muzisanjike Ziphwanyike kukhala tinthu ting’onoting’ono tofanana ndi timiyala.Pa sitepe iyi, kukonza koyambirira kwa mapulasitiki kumalizidwa, ndipo chotsatira ndi momwe angagwiritsire ntchito mapulasitikiwa.
Njira yodziwika kwambiri ndi yophweka kwambiri, yomwe ndi kusungunula pulasitiki pa kutentha kwakukulu ndikukonzanso muzinthu zina.Ubwino wa njirayi ndi kuphweka, liwiro, ndi mtengo wotsika.Vuto lokhalo ndikuti pulasitiki iyenera kusankhidwa mosamala ndikukonzedwanso motere.Kuchita kwa pulasitiki kutsika kwambiri.Komabe, njirayi ndi yoyenera mapulasitiki wamba, monga mabotolo athu akumwa a tsiku ndi tsiku ndi mabotolo ena apulasitiki, omwe amapangidwanso ndikugwiritsidwanso ntchito motere.
Ndiye kodi pali njira iliyonse yobwezeretsanso yomwe singakhudze magwiridwe antchito?Inde, pali, ndiko kuti, mapulasitiki amathyoledwa m'magulu awo oyambirira a mankhwala, monga ma monomers, ma hydrocarbons, ndi zina zotero, ndiyeno amapangidwa kukhala mapulasitiki atsopano kapena mankhwala ena.Njirayi ndi yamwano kwambiri ndipo imatha kugwiritsa ntchito mapulasitiki osakanikirana kapena oipitsidwa, kukulitsa kuchuluka kwa mapulasitiki, ndikuwonjezera mtengo wowonjezera wa mapulasitiki.Mwachitsanzo, ulusi wapulasitiki umapangidwa motere.Komabe, kubwezeretsanso mankhwala kumafuna kugwiritsa ntchito mphamvu zambiri komanso ndalama zambiri, zomwe zikutanthauza kuti ndizokwera mtengo.
Ndipotu, kuwonjezera pa kukonzanso ndi kupanganso mapulasitiki, palinso kutentha kwachindunji kwa pulasitiki m'malo mwa mafuta, ndiyeno kugwiritsa ntchito kutentha komwe kumapangidwa ndi kutentha kwa magetsi kapena ntchito zina.Njira yobwezeretsanso imeneyi ilibe mtengo uliwonse, koma vuto ndi loti idzatulutsa mpweya woipa ndi kuipitsa chilengedwe.Njira yobwezeretsanso iyi sidzaganiziridwa pokhapokha ngati ikufunika.Mapulasitiki okhawo omwe sangathe kupangidwanso mwamakina kapena kupangidwanso ndi mankhwala kapena opanda kufunikira kwa msika ndi omwe angagwiritsidwe ntchito motere.thana ndi.
Chomwe chimakhala chapadera kwambiri ndi pulasitiki yapadera yokhala ndi kuwonongeka.Pulasitiki iyi safuna chithandizo chapadera pambuyo pobwezeretsanso.Ikhoza kuwonongedwa mwachindunji ndi tizilombo toyambitsa matenda ndipo sichidzawononga chilengedwe.Ku Jiangsu Yuesheng Technology Co., Ltd., tagwiritsa ntchito zaka zambiri pakufufuza ndi chitukuko cha zida kuti titsogolere pakupanga zinthu zowonongeka za PLA.Timapereka makasitomala ntchito zoyimitsa kamodzi malinga ndi zosowa zawo zosiyanasiyana ndipo sitifunika kusintha zida zawo zomwe zilipo.Ngati mupanga kusintha kulikonse, mutha kusintha mwachindunji!
Palinso njira zina zapadera zomwe zimayesa kugwiritsa ntchito pulasitiki yobwezeretsanso kupanga mankhwala ena.Mwachitsanzo, kaboni wakuda, womwe umagwiritsidwa ntchito popanga mphira, inki, utoto ndi zinthu zina, umasinthidwa kukhala mpweya wakuda ndi mpweya wina ndi zinyalala zapulasitiki zong'ambika ndi kutentha.Kupatula apo, kwenikweni, zinthuzi, monga mapulasitiki, zimatha kupeza zopangira kudzera mumakampani a petrochemical, kotero sikovuta kumvetsetsa kugwirizana kwawo.
Chodabwitsa kwambiri ndi chakuti pulasitiki yokonzedwanso ingagwiritsidwe ntchito kupanga methanol.Zinyalala za pulasitiki zimasinthidwa kukhala methanol ndi mpweya wina kudzera mu gasification ndi kutembenuka kothandizira.Njirayi imatha kuchepetsa kugwiritsiridwa ntchito kwa gasi wachilengedwe ndikuwonjezera kupanga komanso kuchita bwino kwa methanol.Titapeza methanol, titha kugwiritsa ntchito methanol kupanga formaldehyde, ethanol, propylene ndi zinthu zina.
Inde, njira yeniyeni yobwezeretsanso yomwe imagwiritsidwa ntchito imadalira mtundu wa pulasitiki, monga pulasitiki ya PET, yomwe ndi thermoplastic yowonekera yomwe imagwiritsidwa ntchito popanga mabotolo a zakumwa, zotengera zakudya, ndi zina zotero. .Izi angagwiritsidwe ntchito PET mzere kupanga Jiangsu Yuesheng Technology Co., Ltd., amene makamaka chinkhoswe mu kafukufuku ndi chitukuko cha extruders pulasitiki ndi zipangizo zokhudzana.Ndi kupanga mabizinesi, titha kupereka njira zonse polima zinthu extrusion processing.Gawo la extrusion granulation lomwe lili ndi ufulu wodziyimira pawokha waluso likupitiliza kupita patsogolo ndikubweretsera makasitomala zinthu zabwino kwambiri komanso luso la ogwiritsa ntchito.
Kubwezeretsanso pulasitiki kumathandizira kuchepetsa kudalira mafuta osapsa, kupulumutsa chuma, kuteteza chilengedwe ndi thanzi la anthu, komanso kuchepetsa kutulutsa mpweya wowonjezera kutentha komanso kuvulaza kwa pulasitiki.Zinyalala zamapulasitiki zomwe timataya pamoyo wathu watsiku ndi tsiku, ngati sizigwiritsidwanso ntchito pokonzanso, tsiku lina zidzabwereranso kwa anthu m'njira zina.Chifukwa chake, kwa ife, chofunikira kwambiri ndikuyika zinyalala bwino ndikuzilola kuti zibwezeretsedwe.Iwo amene amapita, amene ayenera kutsalira.Ndiye kodi mukudziwa zobwezeretsanso zinthu zapulasitiki?
