Makapu otayidwa

A chikho chotayidwandi mtundu wa mbale zophikira patebulo komanso ma phukusi a chakudya omwe amatayidwa nthawi imodzi.

Zakudya Zotayidwa Patebulo, Zosankha Zodyera Zimabwera Mu Zinthu Zosiyanasiyana.Makapu otayidwaZilipo m'zinthu zosiyanasiyana, zomwe zimapereka mayankho pazosowa zonse. Zinthu zotayidwa m'makapu nthawi zambiri zimapangidwa ndi thovu, PLA, pepala kapena pulasitiki yamitundu yosiyanasiyana. Chifukwa chake mitundu ya makapu otayidwa m'makapu ndi monga makapu a pepala, makapu apulasitiki ndi makapu a thovu.

Makapu a thovu ndi abwino kwambiri poteteza manja ku zakumwa zotentha komanso kusunga kutentha kwa chakumwa. Polystyrene yowonjezera imagwiritsidwa ntchito popanga makapu a thovu, ndipo polypropylene imagwiritsidwa ntchito popanga makapu apulasitiki.

Popeza amapangidwa kuti agwiritsidwe ntchito kamodzi,makapu otayidwandi zinthu zina zofanana ndi zimenezi zomwe zimatayidwa nthawi imodzi zimakhala gwero lalikulu la zinyalala za ogula ndi zapakhomo, monga zinyalala zamapepala ndi zinyalala zapulasitiki. Akuti pafupifupi banja lililonse limataya pafupifupi zinyalala 70makapu otayidwachaka chilichonse. Zimagwiritsidwanso ntchitomakapu otayidwaZikuoneka kuti chofunika kwambiri ndi kuteteza chilengedwe.

Mitundu yosiyanasiyana ya makapu a mapepala imagwiritsa ntchito zinthu zongowonjezedwanso zochokera ku zomera.

PLA ndi bio-polymer yopangidwa kuchokera kuzinthu zongowonjezwdwanso, kotero makapu a PLA ndi njira yoyenera kwa makampani omwe amasamalira chilengedwe. Makapu a mapepala nthawi zambiri amatha kubwezeretsedwanso ndipo nthawi zambiri amapereka mtengo wabwino kwambiri. Makapu a poly amaletsa kutuluka kwa madzi ndikuchepetsa kuuma kwa madzi.

Zosankha Zosamalira Chilengedwe Chepetsani Kuwononga Chilengedwe

Kutenga njira yowonjezera yogulira makapu osamalira chilengedwe kumawonjezera kusavuta popanda kuwononga ndalama zambiri. Makampani ambiri a makapu amagwiritsa ntchito njira zinazake zokonzera makapu ndi zipangizo kuti apange makapu kukhala okhazikika.

PETchikho cha pulasitiki chotayidwawodzazidwa ndi zakumwa zoledzeretsa zokongola

PET- PET imayimira polyethylene terephthalate. Mbali ya banja la polyester, imagwiritsidwa ntchito popanga ulusi wopangidwa komanso zotengera zakudya ndi zakumwa. Zinthu zopangidwa ndi PET ndi zopepuka ndipo ndi zaluso potseka mpweya, zosungunulira, ndi chinyezi. Ndi zamphamvu komanso zotetezeka ku kugunda.

Zinthu zopangidwa kuchokera ku PET zitha kubwezeretsedwanso.Chikho chotayidwanthawi zambiri amaonedwa ngati zinthu "zobiriwira" kapena "zosamalira chilengedwe".

Mu COPAK, timapanga PET ndi PLA zokha zomwe zimateteza chilengedwemakapu otayidwa.
