Pokhala ndi chidwi chokulirapo pazosankha zowononga zachilengedwe m'malo mwa pulasitiki, makapu amapepala akupeza kutchuka ngati njira ina yoyenera.Komabe, anthu akhala akudandaula za chitetezo chogwiritsira ntchito makapu a mapepala pa zakumwa zotentha.M'nkhaniyi, tikuwunika ngati makapu amapepala ndi njira yabwino yosangalalira chakumwa chomwe mumakonda, ndikukambirana za zoopsa zomwe zingachitike.

1. Kupanga ndi kapangidwe kazinthu:

Makapu amapepala nthawi zambiri amapangidwa ndi kuphatikiza ulusi wamapepala ndi zokutira zopyapyala za polyethylene kuti apereke kukana kutentha ndikuletsa kutulutsa.Mapepala omwe amagwiritsidwa ntchito mu makapu nthawi zambiri amachokera ku nkhalango zokhazikika.Komabe, zomangira za polyethylene zimadzutsa nkhani yotulutsa mankhwala ikakumana ndi kutentha kwambiri.

2. Chemical leaching :

Makapu amapepala akamasunga zakumwa zotentha ngati khofi kapena tiyi, kutentha kumatha kupangitsa kuti chotengera cha polyethylene chilowetse mankhwala mu chakumwa.Mankhwala amodzi omwe angakhale odetsa nkhawa ndi bisphenol A (BPA), omwe amagwirizanitsidwa ndi matenda.Kafukufuku wasonyeza kuti kutulutsa mankhwala kumakhala kochepa pokhapokha ngati chikhocho chikuwonekera ku kutentha kwakukulu kapena kwa nthawi yaitali.

3. Kugwiritsa ntchito moyenera ndi malingaliro :

Kuonetsetsa kuti makapu a mapepala akugwiritsidwa ntchito bwino pa zakumwa zotentha, ndikofunika kutsatira malangizo ena.Sankhani makapu a mapepala omwe amalembedwa kuti "kalasi yachakudya" ndipo amapangidwira zakumwa zotentha.Pewani kusunga zakumwa zotentha m'makapu a mapepala kwa nthawi yayitali, chifukwa izi zingapangitse mwayi wotulutsa mankhwala.Komanso, ganizirani kugwiritsa ntchito manja a kapu kapena tepi yotetezera kuti muchepetse kukhudzana ndi chikhocho.

Mapeto :

Ngakhale makapu amapepala ndi njira yabwino komanso yosamalira zachilengedwe, nkhawa zidakalipo za chitetezo chawo pazakumwa zotentha.Ngakhale kuti kafukufuku wasonyeza kuti kuopsa kwa mankhwala leaching ndi kochepa, tikulimbikitsidwabe kuti malangizo ogwiritsira ntchito mosamala azitsatiridwa.Pamapeto pake, kulingalira njira zina monga makapu ogwiritsidwanso ntchito kungakupatseni zosankha zokhazikika komanso zopanda vuto pazakumwa zotentha.
