PEVA, kapena polyethylene vinyl acetate, ndi mtundu wa pulasitiki womwe wakhala ukugwiritsidwa ntchito kwambiri ngati njira ina ya PVC m'njira zosiyanasiyana, kuphatikizapo matumba a mitembo. PEVA imadziwika kuti ndi njira yabwino kwambiri yosamalira zachilengedwe komanso yotetezeka ku PVC chifukwa chosowa ma phthalates ndi mankhwala ena oyipa.
Ubwino umodzi wogwiritsa ntchito PEVA m'matumba a mitembo ndi momwe zimakhudzira chilengedwe. Mosiyana ndi PVC, PEVA ndi biodegradable ndipo satulutsa mankhwala oopsa m'chilengedwe akatayidwa bwino. PEVA ikasweka, imasinthidwa kukhala madzi, mpweya woipa, ndi biomass, ndikupangitsa kuti ikhale njira yokhazikika.
Phindu lina logwiritsa ntchito PEVA m'matumba a mitembo ndi chitetezo chake. PEVA ilibe phthalates kapena mankhwala ena owopsa omwe nthawi zambiri amawonjezedwa ku PVC. Izi zimapangitsa PEVA kukhala njira yotetezeka yogwirira zotsalira za anthu komanso kwa iwo omwe akumana ndi matumba. Kuonjezera apo, PEVA sichikhoza kuwonongeka pakapita nthawi, kuonetsetsa kuti thumba limakhalabe ndipo limapereka chitetezo chokwanira kwa zotsalira.
PEVA ndi chinthu chosinthika kwambiri kuposa PVC, zomwe zimapangitsa kuti zikhale zosavuta kugwira ndikuwongolera ponyamula mabwinja a anthu. Kusinthasintha kwazinthu kumapangitsa thumba kuti ligwirizane ndi mawonekedwe a thupi, zomwe zingathandize kupewa kutulutsa ndi kutaya.
Pankhani ya kukhazikika, PEVA ndi chinthu cholimba komanso cholimba chomwe chimatha kupirira kuphulika, misozi, ndi kuwonongeka kwina. Izi zimapangitsa kukhala njira yodalirika yosungira ndi kunyamula mabwinja a anthu.
Mmodzi drawback ntchito PEVA matumba mitembo ndi mtengo wake. PEVA nthawi zambiri imakhala yokwera mtengo kuposa PVC, zomwe zimapangitsa kuti ikhale yosasangalatsa kwa mabungwe kapena malo ena. Komabe, mtengo wa PEVA nthawi zambiri umachepetsedwa ndi zopindulitsa zake zachilengedwe ndi chitetezo, ndikupangitsa kuti ikhale yosangalatsa kwanthawi yayitali.
Chodetsa nkhawa china chogwiritsa ntchito PEVA pamatumba a mitembo ndi kupezeka kwake. Ngakhale kuti PEVA ikupezeka kwambiri, mwina sichipezeka mosavuta ngati PVC, yomwe ili yokhazikika kwambiri pamakampani. Komabe, pakudziwitsa za kuopsa kwa chilengedwe ndi thanzi zomwe zimagwirizanitsidwa ndi PVC, mabungwe ambiri atha kusintha kugwiritsa ntchito PEVA ngati njira yokhazikika komanso yotetezeka.
Pankhani ya kutaya, PEVA ikhoza kubwezeretsedwanso, yomwe ndi njira yabwino kwambiri yosamalira zachilengedwe kuposa kuyitaya pamalo otayirapo kapena kuwotcha.

Ponseponse, PEVA imawonedwa kuti ndi yabwino kwa matumba a mitembo chifukwa cha mapindu ake azachilengedwe, chitetezo, komanso kulimba. Ngakhale zingakhale zodula kuposa PVC, ubwino wa nthawi yaitali wogwiritsira ntchito PEVA ukhoza kupitirira mtengo wake. Mabungwe ochulukirapo akazindikira za kuopsa kwa chilengedwe ndi thanzi lomwe limakhudzana ndi PVC, zikutheka kuti ambiri asintha kugwiritsa ntchito PEVA ngati njira yokhazikika komanso yotetezeka yosamalira mabwinja a anthu.
