Anthu amakono amapanga zinyalala zochulukirapo kuposa, mwachitsanzo, zaka 100 zapitazo. Kuchuluka kwa mitundu yonse yamaphukusi, komanso kugwiritsa ntchito zida zowola pang'onopang'ono, kumabweretsa kukula kwa malo otayira zinyalala. Ngati pepala wamba imatha kuwola pakatha zaka 1-2 osavulaza chilengedwe, ndiye kuti mankhwala okongola a polyethylene adzakhala osasintha zaka 10. Kodi chikuchitika ndi chiyani kuthana ndi zinyalala?
Kusanja lingaliro
Zinyalala zapakhomo, zomwe zimatumizidwa kukataya zinyalala tsiku lililonse, ndizosiyana kwambiri. Kwenikweni zonse zimapezeka pakati pawo. Komabe, ngati muphunzira kapangidwe ka zinyalala, mutha kumvetsetsa kuti magawo ake ambiri amatha kusinthidwa. Zikutanthauza chiyani?
Mwachitsanzo, zitini za aluminiyamu zimatha kusungunuka ndikugwiritsa ntchito popanga zinthu zina zotayidwa. Ndi chimodzimodzi ndi mabotolo apulasitiki. Pulasitiki imawonongeka kwa nthawi yayitali kwambiri, chifukwa chake simuyenera kuyembekeza kuti chidebe chomwe chimachokera pansi pamadzi amchere chitha chaka chimodzi kapena ziwiri. Izi ndizopanga zomwe sizipezeka m'chilengedwe ndipo sizikhala pachiwopsezo cha chinyezi, kutentha pang'ono ndi zinthu zina zachilengedwe. Koma botolo la pulasitiki limatha kusungunuka ndikugwiritsidwanso ntchito.
Kodi kusanjidwa kumachitika motani?
Zinyalala zimasankhidwa muzomera zapadera. Uku ndi bizinesi komwe magalimoto onyamula zinyalala amachokera mumzinda komanso komwe zinthu zonse zimapangidwira kuti zichotse mwachangu matani angapo azinyalala zomwe zingapangidwenso.
Maofesi osanja zinyalala amakonzedwa m'njira zosiyanasiyana. Kwinakwake ntchito yamanja imagwiritsidwa ntchito, penapake njira zovuta zimagwiritsidwa ntchito. Pankhani yazitsanzo zazinthu zofunikira, zinyalala zimayenda monyamula pamalo pomwe ogwira ntchito amakhala. Powona chinthu choyenera kukonzedwanso (mwachitsanzo, botolo la pulasitiki kapena thumba la mkaka), amachinyamula kuchokera kunyamula nkumachiyika mu chidebe chapadera.
Mizere yokhayokha imagwira ntchito mosiyana pang'ono. Monga lamulo, zinyalala zochokera m'galimoto zimalowa mu mtundu wina wazida zopepeta nthaka ndi miyala. Nthawi zambiri, ichi chimakhala chithunzi chowoneka bwino - kuyika komwe, chifukwa champhamvu kwambiri, "kumasefa" zomwe zili mu chidebe chachikulu, kukakamiza zinthu zamtundu wina kuti ziwuluke.
Komanso, zinthu zachitsulo zimachotsedwa m'zinyalala. Izi zimachitika popititsa mtanda wotsatira pansi pa maginito. Ndipo ntchitoyo imatha pamanja, chifukwa ngakhale njira yochenjera kwambiri imatha kudumpha zinyalala zamtengo wapatali. Zomwe zatsala pamzere wamsonkho zimayang'aniridwa ndi ogwira ntchito ndipo "zoyambira" zimachotsedwa.
Kusanja ndi kupatula zosonkhanitsa
Nthawi zambiri, mawu awiriwa malinga ndi lingaliro la anthu wamba ndi ofanana. M'malo mwake, kusanja kumamveka kutanthauza kutanthauza kudutsa zinyalala m'malo ovuta. Zosonkhanitsa zosiyana ndizogawa koyamba kwa zinyalala m'makontena osiyana.
Kugawa zinyalala zapakhomo "m'magulu" ndi ntchito ya nzika wamba. Izi zachitika m'maiko onse otukuka ndipo akuyesera kuti achite ku Russia. Komabe, zoyesa zonse pakukhazikitsa zidebe zosiyana m'mizinda ya dziko lathu nthawi zambiri sizimagwedezeka kapena kusuntha. Wokhalako kawirikawiri adzaponyera katoni wamkaka mu thanki yachikaso, ndi bokosi lamaswiti mu lamtambo. Nthawi zambiri, zinyalala zapakhomo zimalowetsedwa m'thumba limodzi ndikuponyedwa mu chidebe choyamba chomwe chimadutsa. Ndiyenera kunena kuti izi nthawi zina zimachitika "pakati". Thumba la zinyalala limatsalira pa kapinga, pakhomo lolowera, m'mbali mwa mseu, ndi zina zambiri.
