Tiyi ndi chakumwa chomwe chimadyedwa kwambiri pambuyo pa madzi ndipo chakhala chakudya chambiri cha anthu kwa zaka zambiri.Kutchuka kwa tiyi kwadzetsa kufunikira kwa tiyi.Kuyika kwa tiyi kwasintha kwazaka zambiri, kuchoka pamasamba otayirira kupita kumatumba a tiyi.Poyambirira, matumba a tiyi adapangidwa kuchokera kuzinthu zosawonongeka monga nayiloni ndi poliyesitala, koma ndi chidziwitso chowonjezeka cha kukhazikika kwa chilengedwe, ogula tsopano akuyang'ana zosankha za thumba la tiyi lothandizira zachilengedwe.Matumba a tiyi osawonongeka opangidwa ndi matumba a fyuluta ya tiyi, pepala losefera, matumba a tiyi a PLA mesh ndi matumba a tiyi a PLA osalukidwa ayamba kutchuka.

Matumba osefera tiyi ndi opyapyala, omveka bwino opangidwa kuchokera ku kuphatikiza kwa mapepala apamwamba kwambiri a sefa ndi polypropylene ya chakudya.Amapangidwa kuti azigwira masamba a tiyi otayirira ndikuthandizira kupanga tiyi.Ndizosavuta, zotsika mtengo komanso zopezeka mosavuta.Zimakhalanso zotetezeka ku chilengedwe komanso thanzi laumunthu, zomwe zimawapangitsa kukhala chisankho chodziwika kwa okonda tiyi.

Sefa pepala, kumbali ina, ndi mtundu wa pepala lachipatala lomwe limagwiritsidwa ntchito kwambiri m'ma laboratory.Ili ndi zosefera zabwino kwambiri ndipo ndiyabwino kugwiritsa ntchito m'matumba a tiyi.Pepala losefera lomwe limagwiritsidwa ntchito m'matumba a tiyi ndi lopangidwa ndi chakudya ndipo limatha kupirira kutentha mpaka madigiri 100 Celsius.Izi zimapangitsa kukhala koyenera kupangira tiyi popanda kusokoneza mtundu wa kusakaniza kapena thanzi la ogula.

Matumba a tiyi a PLA maunaamapangidwa kuchokera ku zinthu zongowonjezwdwa zochokera ku zomera zotchedwa polylactic acid (PLA).Ndi njira ina yosasinthika m'malo mwa nayiloni yachikhalidwe kapena matumba a tiyi a PET.PLA imachokera ku wowuma wa chimanga, nzimbe kapena wowuma wa mbatata, ndikupangitsa kuti ikhale yosamalidwa bwino ndi chilengedwe komanso kompositi.Zinthu za PLA mesh zimakhala ngati thumba la fyuluta ya tiyi popangira tiyi popanda kusokoneza kukoma kapena mtundu wa tiyi.

Pomaliza,Matumba a tiyi a PLA osawombaamapangidwanso kuchokera ku polylactic acid (PLA), koma amabwera mu pepala losalukidwa.Amapangidwa kuti alowe m'malo mwa matumba a tiyi achikhalidwe opangidwa ndi zinthu zosawonongeka.Matumba a tiyi a PLA osalukidwa ndi abwino kwa aliyense amene amakhudzidwa ndi chilengedwe chifukwa amawola mkati mwa masiku 180 ndipo samathandizira kuwononga pulasitiki.

Pomaliza, matumba a tiyi owonongeka omwe amapangidwa ndi zikwama zosefera tiyi, pepala losefera, matumba a tiyi a PLA mesh ndi matumba a tiyi a PLA osalukidwa ndi tsogolo la tiyi.Iwo sali ochezeka ndi chilengedwe, komanso otetezeka komanso abwino kwa ogula.Matumba a tiyi awa sangakhudzenso mtundu kapena kukoma kwa tiyi wanu, kuwapanga kukhala chisankho chabwino kwa okonda tiyi.Chifukwa chake ngati mukufuna kusangalala ndi tiyi ndikuchepetsa kuchuluka kwa mpweya wanu, sankhani matumba a tiyi omwe amatha kuwonongeka ngati matumba anu a tiyi.
