PVC (polyvinyl chloride) tarps ndi PE (polyethylene) tarps ndi zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri zomwe zimagwira ntchito zosiyanasiyana. Mukuyerekeza kwatsatanetsatane uku, tiwona momwe zinthu ziliri, momwe angagwiritsire ntchito, ubwino ndi kuipa kwake kuti tikuthandizeni kupanga chisankho mwanzeru potengera zosowa zanu.
Pankhani yolimba, ma tarps a PVC ndi apamwamba kuposa ma tarps a PE. Ma tarps a PVC adapangidwa kuti azikhala zaka 10, pomwe tarps ya PE nthawi zambiri imakhala zaka 1-2 kapena kugwiritsidwa ntchito kamodzi. Kukhazikika kwapamwamba kwa ma tarps a PVC ndi chifukwa cha kulimba kwawo, kumangidwa mwamphamvu, komanso kukhalapo kwa nsalu zolimba zamkati.
Kumbali ina, ma tarps a PE, omwe amadziwikanso kuti polyethylene tarps kapena HDPE tarpaulins, amapangidwa kuchokera ku mizere ya polyethylene yolukidwa yokutidwa ndi wosanjikiza wa polyethylene yotsika kwambiri (LDPE). Ngakhale sizolimba ngati ma tarps a PVC, ma tarps a PE ali ndi zabwino zawo. Ndi zotsika mtengo, zopepuka komanso zosavuta kuzigwira. Kuphatikiza apo, ndizopanda madzi, zowotcha madzi, komanso zimalimbana ndi UV kuti zitetezedwe ku dzuwa. Komabe, ma tarps a PE amakonda kuphulika ndi misozi, kuwapangitsa kukhala odalirika pang'ono m'mikhalidwe yovuta. Komanso, iwo sakonda zachilengedwe monga tarps canvas.
Tsopano tiyeni tiwone momwe ma tarps awa amagwiritsidwira ntchito. PVC tarps ndi yabwino kugwiritsa ntchito kwambiri. Nthawi zambiri amagwiritsidwa ntchito m'mipanda ya mafakitale kuti apereke chitetezo chapamwamba cha zida. Ntchito zomanga zomanga nthawi zambiri zimagwiritsa ntchito tarps za PVC pomanga, kusungira zinyalala komanso kuteteza nyengo. Kuphatikiza apo, amagwiritsidwa ntchito muzovundikira zamagalimoto ndi ngolo, zovundikira za greenhouses ndi ntchito zaulimi. PVC tarpaulin ndi yoyenera ngakhale zovundikira zakunja zosungirako, kuwonetsetsa kuti nyengo itetezedwa bwino. Kuphatikiza apo, amatchuka ndi anthu oyenda m'misasa komanso okonda panja chifukwa cha kulimba kwawo komanso kudalirika pazosangalatsa.
Mosiyana ndi izi, ma tarpaulins a PE ali ndi mawonekedwe osiyanasiyana ogwiritsira ntchito. Amagwiritsidwa ntchito kwambiri paulimi, zomangamanga, zoyendera komanso zolinga zambiri. Ma tarps a PE amayamikiridwa kuti agwiritsidwe ntchito kwakanthawi komanso kwakanthawi kochepa chifukwa cha kukwera mtengo kwawo. Amapereka chitetezo chokwanira ku nkhungu, mildew ndi zowola, zomwe zimawapangitsa kukhala oyenera malo osiyanasiyana. Komabe, amatha kuphulika ndi misozi, zomwe zimawapangitsa kukhala osayenerera ntchito zolemetsa.
Pomaliza, kusankha pakati pa tarpaulin ya PVC ndi tarpaulin ya PE pamapeto pake zimatengera zomwe mukufuna komanso bajeti. Ma tarp a PVC amakhala olimba kwambiri komanso olimba, kuwapangitsa kukhala abwino kwa ntchito zolemetsa. Kumbali ina, ma tarpaulins a PE ndi otsika mtengo komanso opepuka kuti akwaniritse zosowa zanthawi yochepa komanso zazifupi. Musanasankhe chochita, ganizirani zinthu monga momwe mukufuna kugwiritsira ntchito, kutalika kwake, ndi kuwononga chilengedwe. Ma tarps onse a PVC ndi PE ali ndi zabwino ndi zovuta zawo, choncho sankhani mwanzeru kuti muwonetsetse kuti ndizokwanira pazosowa zanu zenizeni.
