Ndi chitukuko chofulumira cha anthu, anthu ambiri amasankha mavuni a microwave kuti aziwotcha chakudya.Ndizowona kuti mavuni a microwave amabweretsa zabwino zambiri pamoyo wathu, koma tiyeneranso kulabadira chitetezo ndi ukhondo wa chakudya.
Kodi pali zochitika zotere zomwe mukuchitanso, ndipo ngati zili choncho, chonde zisintheni nthawi yomweyo:
Matumba apulasitiki otayika mwachindunji mu uvuni wa microwave kuti atenthe.
Bokosi lotengerako limayikidwa mwachindunji mu microwave kuti liwothe.
Ikani pulasitiki mu microwave kuti mutenthe.
Ikani mbale zapulasitiki mwachindunji mu microwave kuti mutenthe.
Ikani makapu apulasitiki mwachindunji mu microwave kuti mutenthe.
Chifukwa chiyani singatenthetsedwe mwachindunji mu uvuni wa microwave?Tiyeni tiwone kukana kutentha kwakukulu kwa zinthu zapulasitiki zomwe timagwiritsa ntchito nthawi zambiri.
Bungwe la American Society of Plastics Industry (SPI) linapanga zizindikiro zolembera mitundu ya pulasitiki, ndipo China inapanga pafupifupi muyezo womwewo mu 1996. Pamene opanga amapanga zinthu zosiyanasiyana zapulasitiki, adzasindikiza "zidziwitso" mu malo ofanana, omwe amapangidwa ndi zizindikiro zozungulira katatu ndi manambala, ndipo manambala amachokera ku 1 mpaka 7, ofanana ndi mitundu yosiyanasiyana ya pulasitiki.
PET/01
Ntchito: Polyethylene terephthalate, zakumwa, madzi amchere, madzi a zipatso ndi zokometsera nthawi zambiri zimayikidwa m'mabotolo apulasitiki a PET.
Kagwiridwe: Kusamva kutentha kwa 70 ℃, koyenera zakumwa zotentha kapena zakumwa zoziziritsa kukhosi, ndikosavuta kupunduka mukakhala ndi zakumwa zotentha kapena zotenthetsera, ndipo pali zinthu zomwe zimawononga thupi la munthu.Kuphatikiza apo, kugwiritsa ntchito mankhwala apulasitiki a No. 1 kwa nthawi yayitali kumatha kutulutsa carcinogen DEHP.
Malingaliro obwezeretsanso: Bweretsaninso mukangomwa kapena kumwa kuti musagwiritsenso ntchito kwa nthawi yayitali.
HDPE/02
Ntchito: Polyethylene yochuluka kwambiri, yomwe imagwiritsidwa ntchito ngati zotengera zapulasitiki posamba ndi kuyeretsa.
Magwiridwe: kukana kutentha 90 ~ 110C, kukana dzimbiri, asidi ndi kukana zamchere, koma sikophweka kuyeretsa bwino zotsalira.
Lingaliro lobwezeretsanso: Ngati kuyeretsa sikunayende bwino ndipo pangakhale zotsalira za mabakiteriya, ndi bwino kuzibwezeretsanso mwachindunji, ndikupewa kuzigwiritsira ntchito pazida zokhala ndi madzi.
PVC/03
Ntchito: PVC, yomwe ikugwiritsidwa ntchito kwambiri pazinthu zokongoletsera komanso mabotolo omwe siakudya.
Magwiridwe: kutentha kukana 60 ~ 80 ℃, zosavuta kumasula zowonjezera zosiyanasiyana poizoni mukatenthedwa.
Malangizo obwezeretsanso: Mabotolo apulasitiki a PVC savomerezedwa kuti asungidwe zakudya kapena zokometsera.Samalani kupewa kutentha pamene mukubwezeretsanso.
LDPE/04
Ntchito: Otsika kachulukidwe polyethylene, makamaka ntchito filimu chakudya ndi mankhwala pulasitiki mafilimu.
Magwiridwe: Kukana kutentha sikolimba.Kutentha kukadutsa 110 ℃, kukulunga kwa pulasitiki koyenerera kwa PE kudzawoneka chodabwitsa chosungunuka, ndikusiya zokonzekera zapulasitiki zomwe sizingavundike ndi thupi la munthu.Kuonjezera apo, chakudyacho chikatenthedwa ndi kukulunga pulasitiki, mafuta omwe ali m'zakudya amatha kusungunula zinthu zovulaza zomwe zili mu pulasitiki.Chifukwa chake, chakudyacho chikayikidwa mu uvuni wa microwave, chokulunga chapulasitiki chokulungidwa chiyenera kuchotsedwa poyamba.
Malingaliro obwezeretsanso: Kanema wa pulasitiki nthawi zambiri samalimbikitsidwa kuti agwiritsidwenso ntchito.Kuonjezera apo, ngati zokutira zapulasitiki zaipitsidwa kwambiri ndi chakudya, sizingasinthidwenso ndikuyikidwa m'zinyalala zina.
