Ayizizo zonke iitarps ezakhiwe ngendlela efanayo. Nokuba ugubungela izixhobo okanye ukhusela indawo yokwakha, ukukhetha phakathi kwetarps ekhaphukhaphu nenzima kuxhomekeke kwisayensi yezinto zokwakha kunye nolwakhiwo—umahluko ochaphazela ngokuthe ngqo ukuqina nokusebenza.
1. Izixhobo: Isiseko
Iitarpaulin ezikhaphukhaphu zihlala zenziwe nge-polyethylene (PE) — ilaphu elilukiweyo elifakwe iifilimu ezincinci kumacala omabini. Ziqala kwi-5 ukuya kwi-8 mil ubukhulu kunye ne-80 ukuya kwi-200 GSM, kulula ukuzisonga nokuzithwala, kodwa azikwazi ukumelana nexesha elide.
Iitarpaulin eziqinileyo zisebenzisa izinto zoshishino ezifana ne-PVC-coated polyester (vinyl) okanye i-canvas enzima. Iitarpaulin zevinyl zine-polyester scrim ukuze ziqine, zinobukhulu obuyi-12 ukuya kwi-20 mil nangaphezulu, kunye ne-GSM ratings ukusuka kwi-300 ukuya kwi-900. Ezi zinto zenzelwe iimeko ezinzima.
2. Ulwakhiwo: Apho Kwakhiwe khona Ukuqina
Umahluko kwindlela yokwakhiwa kwawo ubaluleke ngokulinganayo. Iitarps ezikhaphukhaphu zisebenzisa iihem ezilula ezisongiweyo okanye ezivalwe ngobushushu ezikrazukileyo lula xa zixinene, ngelixa ii-hem ezinzima zineehem eziqiniswe ngentambo ezisasaza uxinzelelo ngokulinganayo. Ii-grommets kwiimodeli ezikhaphukhaphu ziyiplastiki okanye isinyithi esikhaphukhaphu, ezibekwe kwindawo emalunga nemitha enye ukusuka kwenye, kwaye zinokuphuma ngaphandle kwamandla amaninzi. Iitarps ezikhaphukhaphu, ngokwahlukileyo, zisebenzisa ii-grommets zentsimbi engagqwaliyo okanye zentsimbi engagqwaliyo ezibekwe kwindawo nganye kwiisentimitha ezingama-45 ukuya kuma-60, kunye nokuqinisa iikona ukuthintela ukukrazuka. Ii-seams zikwabalisa ibali: iitarps ezikhaphukhaphu zixhomekeke ekuthungeni okutshisiweyo okanye okuqhelekileyo okuhlala kuvuza emva kokuvezwa yi-UV, ngelixa iitarps zevinyl ezikhaphukhaphu zisebenzisa ii-seams ezitshisiweyo ezihlala zingangeni manzi kangangeminyaka.
3. Ukusebenza: Umahluko wokwenyani kwihlabathi
Xa kufikwa ekuthinteleni amanzi, ii-tarps ezikhaphukhaphu zisebenza kakuhle xa zintsha, kodwa ii-seams kunye nee-grommets ziindawo ezibuthathaka ezidla ngokukhokelela ekuvuzeni. Ii-tarps ze-PVC ezinzima azingeni manzi ngokupheleleyo, kwaye ii-seams zazo ezidityanisiweyo ziqinisekisa ukuba amanzi ahlala ixesha elide; ii-tarps ze-canvas zibonelela ngomgangatho ophakathi—azinamanzi kwaye ziyaphefumla, nto leyo ezenza zibe zilungele ukusetyenziswa apho umoya ubalulekile khona.
Ukuxhathisa i-UV ngomnye umgca omkhulu owahlulahlulayo. Ii-polyethylene tarps eziqhelekileyo azinazo izithinteli ze-UV ezaneleyo kwaye zihlala zibuthathaka kwiinyanga ezi-6 ukuya kwezi-12 emva kokuvezwa elangeni ngqo. Nangona kunjalo, ii-vinyl tarps zoshishino ziquka iziqinisi ze-UV kwaye zinokuhlala iminyaka emi-5 ukuya kweli-10 ngaphandle, ngelixa i-canvas ephathwayo inika iminyaka emi-3 ukuya kwemi-5 efanelekileyo.
Ukunyamezela amaqondo obushushu nako kwahlukile. Ii-tarps ezikhaphukhaphu zisebenza ngokuthembekileyo phakathi kwe--20°C kunye ne-60°C (–4°F ukuya kwi-140°F), kodwa ziqina kwiimeko zokubanda. Ii-tarps ze-PVC ezinzima zimelana nobubanzi, ukusuka kwi--30°C ukuya kwi-70°C (–22°F ukuya kwi-158°F), kwaye ezininzi ziyahlangabezana nemigangatho ethintela ilangatye—uphawu olubalulekileyo lokhuseleko olusetyenziswa kwimizi-mveliso.
Ukuphefumla kuhlala kungajongwa kodwa kubaluleke kakhulu. Iitarps ezikhaphukhaphu aziphefumli, zibamba umswakama ngaphantsi kwaye zinokubangela umhlwa okanye ukungunda. Iitarps zecanvas ezinzima ziyaphefumla ngokwendalo, nto leyo eyenza ukuba zibe lolona khetho lukhethwayo lokugubungela izixhobo, umthi, okanye ingca apho umoya ungena khona. Iitarps zevinyl, nangona zingaphefumli, ziyabalasela xa ukuthintela amanzi ngokupheleleyo kuyeyona nto iphambili.
4. Ingongoma ephambili
Iitarps ze-PE ezikhaphukhaphu ziyindlela engabizi kakhulu kwiimfuno zexesha elifutshane nezexeshana. Kwiindawo ezingaphandle ixesha elide, kwiimeko zomoya ophezulu, okanye usetyenziso olufuna ukuthotyelwa kokhuseleko, iitarps ze-PVC ezinzima okanye zecanvas ezilungisiweyo zibonelela ngokuqina nokusebenza okuphezulu. Ukukhetha itarps efanelekileyo akupheleli nje kubungakanani—kumalunga nokuqonda ubukhulu be-mil, i-GSM, kunye neenkcukacha zokwakha ezigqiba ukuba isigqubuthelo sakho sihlala ixesha elide okanye iminyaka elishumi.
