M'moyo wathu watsiku ndi tsiku, mabotolo apulasitiki amatha kuwoneka kulikonse.Ndikudabwa ngati mwawona kuti pali chizindikiro cha manambala chopangidwa ngati chizindikiro cha makona atatu pansi pa mabotolo ambiri apulasitiki (makapu).
Mwachitsanzo:
Mabotolo amadzi amchere, olembedwa 1 pansi;
Makapu apulasitiki osagwira kutentha kwa tiyi, olembedwa 5 pansi;
Mabotolo a Zakudyazi nthawi yomweyo ndi mabokosi akudya mwachangu, pansi akuwonetsa 6;
…
Monga momwe aliyense akudziwira, zolemba pansi pa mabotolo apulasitikiwa ali ndi matanthauzo ozama, omwe ali ndi "chiwopsezo cha poizoni" cha mabotolo apulasitiki ndikuyimira kukula kwa zinthu zomwe zimagwiritsidwa ntchito ndi pulasitiki.
"Nambala ndi ma code omwe ali pansi pa botolo" ndi gawo la chizindikiritso chazinthu zapulasitiki zomwe zafotokozedwa mumiyezo yadziko:
Chizindikiro chobwezeretsanso makona atatu pansi pa botolo la pulasitiki chimasonyeza kubwezeretsedwanso, ndipo manambala 1-7 amasonyeza mtundu wa utomoni womwe umagwiritsidwa ntchito mu pulasitiki, zomwe zimapangitsa kuti zikhale zosavuta komanso zosavuta kuzindikira zipangizo zapulasitiki zomwe zimagwiritsidwa ntchito.
"1" PET - polyethylene terephthalate
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Izi sizimatentha mpaka 70 ° C ndipo ndizoyenera kunyamula zakumwa zotentha kapena zozizira.Zimapunduka mosavuta zikadzazidwa ndi zakumwa zotentha kwambiri kapena zotenthedwa, ndipo zinthu zovulaza thupi la munthu zimatha kusungunuka;Nthawi zambiri mabotolo amadzi amchere ndi mabotolo akumwa a carbonated amapangidwa ndi izi.
Choncho, nthawi zambiri tikulimbikitsidwa kutaya mabotolo a zakumwa mukatha kuwagwiritsa ntchito, osawagwiritsanso ntchito, kapena kuwagwiritsa ntchito ngati zosungiramo zosungiramo zinthu zina.
"2" HDPE - polyethylene yapamwamba kwambiri
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Izi zimatha kupirira kutentha kwa 110 ° C ndipo nthawi zambiri zimagwiritsidwa ntchito popanga mabotolo amankhwala oyera, zotsukira, ndi zotengera zapulasitiki zosambira.Matumba ambiri apulasitiki omwe panopa amagwiritsidwa ntchito m'masitolo akuluakulu kuti azisungira chakudya amapangidwanso ndi zinthuzi.
Chidebe chamtunduwu sichapafupi kuyeretsa.Ngati kuyeretsa sikuli bwino, zinthu zoyambirirazo zidzakhalabe ndipo sizovomerezeka kuti zibwezeretsedwe.
"3" PVC - polyvinyl kolorayidi
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Izi zimatha kupirira kutentha kwa 81 ° C, zili ndi pulasitiki yabwino kwambiri, komanso ndizotsika mtengo.Ndizosavuta kupanga zinthu zovulaza pa kutentha kwakukulu ndipo zimatulutsidwa ngakhale panthawi yopanga.Zinthu zapoizoni zikalowa m’thupi la munthu ndi chakudya, zingayambitse khansa ya m’mawere, kubadwa kwa ana obadwa kumene ndi matenda ena..
Pakalipano, zinthuzi zimagwiritsidwa ntchito kwambiri mu malaya amvula, zipangizo zomangira, mafilimu apulasitiki, mabokosi apulasitiki, ndi zina zotero, ndipo sagwiritsidwa ntchito kawirikawiri kunyamula chakudya.Ngati agwiritsidwa ntchito, onetsetsani kuti asatenthedwe.
"4" LDPE - polyethylene yotsika kwambiri
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Mtundu uwu wa zinthu ulibe kukana kutentha kwamphamvu ndipo umagwiritsidwa ntchito kwambiri popanga filimu yodyera ndi filimu yapulasitiki.
Nthawi zambiri, filimu yodalirika ya PE idzasungunuka pamene kutentha kumapitirira 110 ° C, ndikusiya zokonzekera zapulasitiki zomwe sizingawonongeke ndi thupi la munthu.Komanso, chakudya chikakulungidwa mu filimu ya chakudya ndikutenthedwa, mafuta omwe ali muzakudya amasungunuka mosavuta mufilimu yodyera.zinthu zoipa zimasungunuka.
Choncho, tikulimbikitsidwa kuti chakudya chokulungidwa mu pulasitiki chichotsedwe musanachiike mu uvuni wa microwave.
"5" PP - polypropylene
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Izi, zomwe nthawi zambiri zimagwiritsidwa ntchito popanga mabokosi a chakudya chamasana, zimatha kupirira kutentha kwa 130 ° C ndipo siziwoneka bwino.Ndilo bokosi lokhalo lapulasitiki lomwe lingathe kuikidwa mu uvuni wa microwave ndipo lingagwiritsidwenso ntchito pambuyo poyeretsa bwino.
Komabe, ziyenera kudziwidwa kuti mabokosi ena ankhomaliro amakhala ndi “5″ pansi, koma “6” pachivundikirocho.Pankhaniyi, tikulimbikitsidwa kuti chivindikirocho chichotsedwe pamene bokosi la nkhomaliro likuyikidwa mu uvuni wa microwave, osati pamodzi ndi bokosi la bokosi.Ikani mu microwave.
“6″ PS——Polystyrene
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Zinthu zamtunduwu zimatha kupirira kutentha kwa madigiri 70-90 ndipo zimakhala zowonekera bwino, koma sizingayikidwe mu uvuni wa microwave kuti musatulutse mankhwala chifukwa cha kutentha kwambiri;ndipo kukhala ndi zakumwa zotentha kumatulutsa poizoni ndikutulutsa styrene ikawotchedwa.Nthawi zambiri amagwiritsidwa ntchito popanga Zinthu zopangira mabokosi amtundu wa mbale komanso mabokosi a chakudya chofulumira.
Choncho, tikulimbikitsidwa kuti tipewe kugwiritsa ntchito mabokosi a chakudya chofulumira kunyamula chakudya chotentha, kapena kuwagwiritsa ntchito kuti agwire ma asidi amphamvu (monga madzi a lalanje) kapena zinthu zamphamvu zamchere, chifukwa zidzawola polystyrene yomwe siili yabwino kwa thupi la munthu ndipo imatha. mosavuta kuyambitsa khansa.
"7" Zina - PC ndi zizindikiro zina zapulasitiki
Kodi kapu yapulasitiki yomwe mumamwa ndi yapoizoni?Ingoyang'anani manambala omwe ali pansi ndikupeza!
Izi ndizinthu zomwe zimagwiritsidwa ntchito kwambiri, makamaka popanga mabotolo a ana, makapu am'mlengalenga, etc. Komabe, zakhala zotsutsana m'zaka zaposachedwa chifukwa zimakhala ndi bisphenol A;Choncho, samalani ndi kumvetsera mwapadera mukamagwiritsa ntchito chidebe chapulasitiki ichi.
Ndiye, mutamvetsetsa matanthauzo a zilembo zapulasitikizi, mungasokoneze bwanji "chiwopsezo" cha mapulasitiki?
Njira 4 zodziwira kawopsedwe
(1) Kuyezetsa maganizo
Matumba apulasitiki opanda poizoni ndi oyera ngati amkaka, owoneka bwino, kapena opanda mtundu komanso owoneka bwino, osinthika, osalala mpaka kukhudza, ndipo amawoneka kuti ali ndi phula pamwamba;matumba apulasitiki okhala ndi poizoni amakhala ndi utoto wonyezimira kapena wopepuka wachikasu ndipo amamva ngati akumata.
(2) Kudziŵika kwa jitter
Tengani mbali imodzi ya thumba la pulasitiki ndikugwedeza mwamphamvu.Ngati imveketsa bwino, ilibe poizoni;ngati ingolira, ndi yapoizoni.
(3) Kuyesa madzi
Ikani thumba la pulasitiki m'madzi ndikulisindikiza pansi.Chikwama chapulasitiki chosakhala ndi poizoni chimakhala ndi mphamvu yokoka yaying'ono ndipo imatha kuyandama pamwamba.Chikwama chapulasitiki chapoizoni chimakhala ndi mphamvu yokoka yayikulu ndipo chidzamira.
(4) Kuzindikira moto
Matumba apulasitiki opanda poizoni a polyethylene amatha kuyaka, okhala ndi malawi a buluu ndi nsonga zachikasu.Akayaka, amadontha ngati misozi ya kandulo, kununkhiza kwa parafini, komanso kutulutsa utsi wochepa.Matumba apulasitiki a poizoni a polyvinyl chloride satha kuyaka ndipo amazimitsa akangochotsedwa pamoto.Ndi yachikasu pansi yobiriwira, imatha kukhala yanyimbo ikafewetsedwa, ndipo imakhala ndi fungo loyipa la hydrochloric acid.
