Matumba opanda nsalu ndi okonda zachilengedwe kuposa matumba apulasitiki

Chikwama chosalukidwa (chomwe chimadziwika kuti thumba lopanda nsalu) ndi chinthu chobiriwira, cholimba komanso chokhazikika, chokongola, chowoneka bwino, chowoneka bwino, chowoneka bwino, chosinthikanso, chotsuka, kutsatsa kwazithunzi za silika, kuyika chizindikiro, moyo wautali wautumiki, woyenera kampani iliyonse, makampani aliwonse ngati zotsatsa Zotsatsa ndi mphatso.Ogula amapeza chikwama chokongola chosalukidwa akamagula, ndipo mabizinesi amapeza zabwino kwambiri padziko lonse lapansi ndi zotsatsa zosawoneka, kotero kuti nsalu zosalukidwa zikuchulukirachulukira pamsika.

Matumba ogula osalukidwa ndi nsalu zopanda nsalu zopangidwa ndi pulasitiki.Anthu ambiri amaganiza kuti nsalu ndi chinthu chachilengedwe, koma kwenikweni ndi kusamvetsetsana.Zopangira zomwe zimagwiritsidwa ntchito kwambiri pansalu yopanda nsalu ndi polypropylene (PP mu Chingerezi, yomwe imadziwika kuti polypropylene) kapena polyethylene terephthalate (PET mu Chingerezi, yomwe imadziwika kuti polyester).Zopangira zamatumba apulasitiki ndi polyethylene, ngakhale mayina azinthu ziwirizi ndi ofanana., Koma kapangidwe ka mankhwala ndi kosiyana kwambiri.Mapangidwe a molekyulu a polyethylene ndi okhazikika komanso ovuta kwambiri kuti awonongeke, choncho zimatenga zaka 300 kuti matumba apulasitiki awonongeke;pamene mankhwala a polypropylene sali olimba, unyolo wa mamolekyu ukhoza kusweka mosavuta, womwe ukhoza kuonongeka bwino, Ndipo lowetsani mkombero wotsatira wa chilengedwe mu mawonekedwe osakhala poizoni, thumba logulitsira lopanda nsalu likhoza kuwonongeka kwathunthu mkati mwa masiku 90. .Kwenikweni, polypropylene (PP) ndi mtundu wa pulasitiki, ndipo kuipitsa chilengedwe pambuyo potaya ndi 10% yokha ya matumba apulasitiki.

Chogulitsacho chimagwiritsa ntchito nsalu zosalukidwa ngati zopangira.Ndi mbadwo watsopano wa zipangizo zachilengedwe.Zili ndi makhalidwe a chinyezi, mpweya, kusinthasintha, kulemera kochepa, kosayaka, kosavuta kuwonongeka, kopanda poizoni komanso kosakwiyitsa, kolemera mumtundu, kutsika mtengo, ndi kubwezeretsanso.Zinthuzi zimatha kuwonongeka mwachilengedwe zikayikidwa panja kwa masiku 90, ndipo zimakhala ndi moyo wautumiki mpaka zaka 5 zikayikidwa m'nyumba.Ndiwopanda poizoni, wosanunkhiza, ndipo ulibe zinthu zotsalira ukawotchedwa, choncho suipitsa chilengedwe.Imazindikiridwa padziko lonse ngati chinthu chosagwirizana ndi chilengedwe chomwe chimateteza chilengedwe cha dziko lapansi.
