Iitayile zePVC (iPolyvinyl Chloride) kunye nePE (Polyethylene) ziindidi ezimbini eziqhelekileyo zezigqubuthelo ezingangeni manzi ezisetyenziswa kwimizi-mveliso eyahlukeneyo. Nalu uthelekiso lweepropati kunye nokusetyenziswa kwazo:
1. Itarpaulin yePVC
- Izinto: Yenziwe nge-polyvinyl chloride, ehlala iqiniswa nge-polyester okanye i-mesh yamandla.
- Iimbonakalo:
-Yomelele kakhulu kwaye iyaxhathisa iinyembezi.
- Ukugqwesa kwamanzi kunye nokuchasana kwe-UV (xa uphathwa).
-Iinketho zokunqanda umlilo ziyafumaneka.
- Ukumelana neekhemikhali, ukungunda kunye nokubola.
-Umsebenzi onzima kwaye uhlala ixesha elide.
- Ukusebenza kakuhle kweendleko:I-PVC ineendleko zokuqala eziphezulu kodwa ixabiso elide ekuhambeni kwexesha.
- Impembelelo yokusingqongileyo: I-PVC ifuna ukulahlwa okukhethekileyo ngenxa yesiqulatho seklorine.
-Izicelo:
-Izigqubuthelo zelori, iindawo zokuhlala kwimizi-mveliso, iintente.
- Amagquma aselwandle (iitarp zesikhephe).
- Iibhena zentengiso (ngenxa yokuprintwa).
- Ukwakhiwa kunye nezolimo (ukhuseleko olunzima).
2. PE Tarpaulin
- Izinto eziphathekayo: Yenziwe kwi-polyethylene ephothiweyo (i-HDPE okanye i-LDPE), idla ngokugqunywa ukuze ingangeni manzi.
- Iimbonakalo:
-Ikhaphukhaphu kwaye ibhetyebhetye.
-Amanzi kodwa ahlala ixesha elide kunePVC.
-Ukunganyangeki kancinci kwi-UV kunye nemozulu egqithisileyo (inokuthomalalisa ngokukhawuleza).
- Ukusebenza kakuhle kweendleko:Ixabiso eliphantsi kunePVC.
- Ayinamandla kangako xa ikrazulwa okanye ukukrazuka.
-Impembelelo yokusiNgqongileyo: I-PE kulula ukuyigalela kwakhona.
-Izicelo:
- Amagquma exeshana (umzekelo, ifanitshala yangaphandle, iimfumba zeenkuni).
-Iithaphu zokukhempisha ezikhaphukhaphu.
- Ezolimo (izigqubuthelo zegreenhouse, ukukhuselwa kwezityalo).
- Ulwakhiwo lwexesha elifutshane okanye amaqweqwe emisitho.
Yiyiphi Omawuyikhethe?
-PVC ingcono ixesha elide, enzima-umsebenzi, kunye nokusetyenziswa kwezoshishino.
- I-PE ilungele iimfuno zethutyana, ezikhaphukhaphu, kunye nezohlahlo lwabiwo-mali.
