Si ma tarps onse omwe amamangidwa mofanana. Kaya mukuphimba zida kapena kuteteza malo omangira, kusankha pakati pa tarp yopepuka ndi yolemera kumadalira sayansi ya zinthu ndi kapangidwe—kusiyana komwe kumakhudza mwachindunji kulimba ndi magwiridwe antchito.
1. Zipangizo: Maziko
Ma tarpaulin opepuka nthawi zambiri amapangidwa ndi polyethylene (PE) — nsalu yolukidwa yokhala ndi mapepala opyapyala mbali zonse ziwiri. Popeza ndi makulidwe kuyambira 5 mpaka 8 mil ndi 80 mpaka 200 GSM, ndi osavuta kupindika ndi kunyamula, koma satha kupirira nthawi yayitali.
Ma tarpaulin olemera amagwiritsa ntchito zipangizo zamafakitale monga polyester yophimbidwa ndi PVC (vinyl) kapena canvas yolemera. Ma tarpaulin a vinyl ali ndi chivundikiro cha polyester kuti chikhale cholimba, chokhala ndi makulidwe a 12 mpaka 20 mil kapena kuposerapo, ndi ma GSM ratings kuyambira 300 mpaka kupitirira 900. Zipangizozi zimapangidwa kuti zigwirizane ndi zinthu zovuta kwambiri.
2. Kapangidwe: Kumene Kulimba Kumamangidwa
Kusiyana kwa kapangidwe kake n'kofunika kwambiri. Ma tarps opepuka amagwiritsa ntchito ma hem osavuta kupindika kapena otsekedwa ndi kutentha omwe amang'ambika mosavuta akamapanikizika, pomwe ma tarps olemera amakhala ndi ma hem olimbikitsidwa ndi chingwe omwe amagawa kupsinjika mofanana. Ma grommets pa ma model opepuka ndi apulasitiki kapena achitsulo chopepuka, omwe amakhala patali pafupifupi mita imodzi, ndipo amatha kutuluka popanda mphamvu zambiri. Ma tarps olemera, mosiyana, amagwiritsa ntchito ma grommets achitsulo chosapanga dzimbiri kapena osapanga dzimbiri omwe amakhala patali masentimita 45 mpaka 60 aliwonse, okhala ndi zolimbitsa ngodya kuti asang'ambike. Ma straps amanenanso nkhani: ma tarps opepuka amadalira kusoka kotenthedwa ndi kutentha kapena wamba komwe nthawi zambiri kumatuluka pambuyo pa kuwala kwa UV, pomwe ma tarps olemera a vinyl amagwiritsa ntchito ma strams otenthedwa ndi kutentha omwe amakhalabe osalowa madzi kwa zaka zambiri.
3. Magwiridwe antchito: Kusiyana kwa Dziko Lenileni
Ponena za kuletsa madzi kulowa m'madzi, ma tarps opepuka amagwira ntchito bwino akamakhala atsopano, koma ma straps ndi ma grommets ndi malo ofooka omwe nthawi zambiri amachititsa kuti madzi atuluke. Ma tarps a PVC olemera salowa madzi konse, ndipo ma straps awo olumikizidwa amatsimikizira kuti salowa madzi kwa nthawi yayitali; ma tarps a canvas amapereka malo apakati—osalowa madzi komanso opumira, zomwe zimapangitsa kuti akhale abwino kugwiritsa ntchito pamene mpweya ukuyenda bwino.
Kukana kwa UV ndi mzere wina waukulu wogawanitsa. Ma polyethylene tarps okhazikika alibe zoletsa zokwanira za UV ndipo nthawi zambiri amakhala ofooka mkati mwa miyezi 6 mpaka 12 kuchokera padzuwa. Komabe, ma vinyl tarps amapangidwa ndi ma UV stabilizers ndipo amatha kukhala zaka 5 mpaka 10 panja, pomwe canvas yokonzedwa bwino imapereka zaka 3 mpaka 5 zabwino.
Kulekerera kutentha kumasiyananso. Ma tarps opepuka amagwira ntchito bwino pakati pa -20°C ndi 60°C (–4°F mpaka 140°F), koma amakhala olimba mu nthawi yozizira kwambiri. Ma tarps a PVC olemera amatha kupirira kutentha kwakukulu, kuyambira -30°C mpaka 70°C (–22°F mpaka 158°F), ndipo ambiri amakwaniritsa miyezo yoletsa moto—chinthu chofunikira kwambiri pachitetezo chomwe chimagwiritsidwa ntchito m'mafakitale.
Kupuma bwino nthawi zambiri kumanyalanyazidwa koma n'kofunika kwambiri. Ma tarps opepuka sapuma, amatseka chinyezi pansi ndipo amatha kuyambitsa dzimbiri kapena nkhungu. Ma tarps olemera a canvas amatha kupuma mwachilengedwe, zomwe zimapangitsa kuti azigwiritsidwa ntchito popangira zida, matabwa, kapena udzu komwe mpweya umakhala wofunikira. Ma tarps a vinyl, ngakhale kuti sapuma bwino, amachita bwino kwambiri pamene kutsekereza madzi mokwanira ndiko chinthu chofunika kwambiri.
4. Mfundo Yofunika Kwambiri
Ma tarps opepuka a PE ndi chisankho chotsika mtengo pa zosowa zakanthawi kochepa. Kuti muwoneke panja kwa nthawi yayitali, nyengo yamphepo yamphamvu, kapena kugwiritsa ntchito komwe kumafuna kutsatira chitetezo, ma tarps olemera a PVC kapena canvas okhala ndi mankhwala amapereka kulimba komanso magwiridwe antchito abwino kwambiri. Kusankha tarp yoyenera sikungokhudza kukula kokha - koma kumvetsetsa makulidwe a mil, GSM, ndi tsatanetsatane wa kapangidwe kake zomwe zimatsimikiza ngati chivundikiro chanu chimatenga nyengo imodzi kapena khumi.
