PVC (Polyvinyl Chloride) ndi PE (Polyethylene) tarpaulins ndi mitundu iwiri yodziwika bwino ya zovundikira zopanda madzi zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Nayi kufananitsa kwa katundu wawo ndi ntchito:
1. PVC Tarpaulin
- Zida: Zopangidwa kuchokera ku polyvinyl chloride, zomwe nthawi zambiri zimalimbikitsidwa ndi poliyesitala kapena mauna kuti azilimba.
- Mawonekedwe:
- Zolimba kwambiri komanso zosagwirizana ndi misozi.
- Kuteteza madzi kwabwino komanso kukana kwa UV (pamene wathandizidwa).
- Zosankha zozimitsa moto zilipo.
- Kulimbana ndi mankhwala, mildew ndi zowola.
- Ntchito yolemetsa komanso yokhalitsa.
- Mtengo Mwachangu:PVC ili ndi ndalama zoyambira zapamwamba koma zotalikirapo pakapita nthawi.
- Mphamvu Zachilengedwe: PVC imafuna kutayidwa mwapadera chifukwa cha chlorine.
- Mapulogalamu:
- Zophimba zamagalimoto, malo okhala mafakitale, mahema.
- Zophimba zam'madzi (maboti a tarps).
- Zikwangwani zotsatsa (chifukwa cha kusindikiza).
- Ntchito yomanga ndi ulimi (chitetezo cholemetsa).
2. PE Tarpaulin
- Zida: Zopangidwa kuchokera ku polyethylene (HDPE kapena LDPE), yomwe nthawi zambiri imakutidwa kuti isatseke madzi.
- Mawonekedwe:
- Wopepuka komanso wosinthika.
- Wopanda madzi koma osalimba kuposa PVC.
- Kusagonjetsedwa ndi UV komanso nyengo yoopsa (imatha kutsika mwachangu).
- Mtengo Mwachangu:Zotsika mtengo kuposa PVC.
- Osalimba motsutsana ndi kung'ambika kapena kuyabwa.
-Environmental Impact: PE ndiyosavuta kuyikonzanso.
- Mapulogalamu:
- Zovala zosakhalitsa (monga mipando yakunja, milu yamatabwa).
- Ma tarps opepuka amisasa.
- Ulimi (zophimba zobiriwira, kuteteza mbewu).
- Zomangamanga zazifupi kapena zophimba zochitika.
Iti Yoti Musankhe?
- PVC ndi yabwino kwa nthawi yayitali, yolemetsa, komanso yogwiritsidwa ntchito m'mafakitale.
- PE ndiyabwino pazosowa kwakanthawi, zopepuka komanso zokomera bajeti.
