I-PVC (i-polyvinyl chloride) i-tarps kunye ne-PE (i-polyethylene) i-tarps zizinto ezimbini ezisetyenziswa ngokubanzi ezisebenza ngeenjongo ezahlukeneyo. Kolu thelekiso lubanzi, siza kuphonononga kwiipropati zabo eziphathekayo, izicelo, izinto eziluncedo nezingeloncedo ukukunceda wenze isigqibo esisekelwe kwiimfuno zakho ezithile.
Ngokumalunga nokuqina, iitarp zePVC ziphezulu kune PE tarps. Iitarps zePVC ziyilelwe ukuhlala ukuya kutsho kwiminyaka eli-10, ngelixa iitarps ze-PE zihlala kuphela iminyaka eyi-1-2 okanye ukusetyenziswa kanye. Ukomelela okugqwesileyo kweetarp zePVC kungenxa yokuqina kwazo, ulwakhiwo olunamandla, kunye nobukho belaphu eliqinileyo lemesh yangaphakathi.
Kwelinye icala, iitarp zePE, ezaziwa ngokuba ziitarps zepolyethylene okanye iitarpauli ze-HDPE, zenziwe ngemicu ye-polyethylene elukiweyo eqatywe umaleko we-polyethylene ephantsi (LDPE). Nangona ingenako ixesha elide njengePVC tarps, iitarps zePE zineenzuzo zazo. Zingabizi kakhulu, zikhaphukhaphu kwaye kulula ukuzibamba. Ngaphezu koko, awanamanzi, awanyangeki amanzi, kwaye awanyangeki kwi-UV ukuze akhuseleke kakhulu elangeni. Nangona kunjalo, i-PE tarps ithanda ukugqobhoza kunye neenyembezi, izenza zithembeke kancinci kwiimeko ezinzima. Kwakhona, azikho buhlobo ngokwendalo njengeetarp zecanvas.
Ngoku makhe siphonononge usetyenziso lwezi tarps. Iitarp zePVC zilungele ukusetyenziswa komsebenzi onzima. Zihlala zisetyenziselwa kwiindawo ezivaliweyo zoshishino ukubonelela ngokhuseleko oluphezulu lwezixhobo. Iiprojekthi zokwakha zezakhiwo zihlala zisebenzisa i-PVC tarps kwi-scaffolding, i-debris containment kunye nokukhusela imozulu. Ukongeza, zisetyenziselwa iilori kunye neetrailer ezigubungelayo, iikhava ze-greenhouse kunye nezicelo zezolimo. Iseyile yePVC ifanelekile nakwizigqubuthelo zogcino lwangaphandle, iqinisekisa ukhuseleko lwemozulu ngeyona ndlela. Ukongeza, zithandwa ngabakhempisi kunye nabathandi bangaphandle ngenxa yokuqina kunye nokuthembeka kwiindawo zokuzonwabisa.
Ngokwahlukileyo, iiseyile ze-PE zinoluhlu olubanzi lweemeko zesicelo. Ngokuqhelekileyo zisetyenziselwa ezolimo, ukwakhiwa, ukuthutha kunye neenjongo eziqhelekileyo. Iitarp zePE zithandwa ukuba zisetyenziswe okwethutyana nangexesha elifutshane ngenxa yokusebenza kakuhle kweendleko. Banikezela ngokhuseleko olwaneleyo kwisikhunta, ukubola kunye nokubola, okwenza ukuba bafaneleke kwiindawo ezahlukeneyo. Nangona kunjalo, bathambekele kwi-punctures kunye neenyembezi, ezibangela ukuba zingabikho ukufaneleka kwizicelo ezinzima.
Ukuqukumbela, ukukhetha phakathi kwetarpaulin yePVC kunye netarpaulin ye-PE ekugqibeleni kuxhomekeke kwiimfuno zakho kunye nohlahlo lwabiwo-mali. Iitarps zePVC zinokomelela kunye nokomelela okukhethekileyo, zizenza zilungele usetyenziso olunzima. Kwelinye icala, iiseyile ze-PE zineendleko ezisebenzayo kwaye zikhaphukhaphu ukuhlangabezana neemfuno zexeshana nezexeshana. Phambi kokwenza isigqibo, qwalasela imiba enjengokusetyenziswa okucetywayo, ukuba iya kuhlala ixesha elingakanani, kunye nefuthe lokusingqongileyo. Zombini i-PVC kunye ne-PE tarps zineenzuzo kunye nezingeloncedo zazo, ngoko ke khetha ngobulumko ukuqinisekisa okona kufanelekileyo kwiimfuno zakho ezithile.
