ʻAʻole like ke kūkulu ʻia ʻana o nā tarp āpau. Inā ʻoe e uhi ana i nā lako a i ʻole e pale ana i kahi kahua kūkulu, ʻo ke koho ʻana ma waena o ka tarp māmā a me ka tarp kaumaha e pili ana i ka ʻepekema mea a me ke kūkulu ʻana—nā ʻokoʻa e pili pono ana i ke kūpaʻa a me ka hana.
1. Nā Mea Hana: Ke Kumu
ʻO ka maʻamau, hana ʻia nā tarpaulins māmā mai ka polyethylene (PE) — he lole ulana i laminated me nā ʻili lahilahi ma nā ʻaoʻao ʻelua. Mai 5 a 8 mil ka mānoanoa a me 80 a 200 GSM, maʻalahi lākou e pelu a lawe, akā ʻaʻohe o lākou kūpaʻa lōʻihi.
Hoʻohana nā tarpaulins hana kaumaha i nā mea ʻoihana e like me ka polyester i uhi ʻia me ka PVC (vinyl) a i ʻole ka canvas kaumaha. Loaʻa i nā tarps vinyl kahi scrim polyester no ka ikaika tensile, me nā mānoanoa o 12 a 20 mil a ʻoi aku paha, a me nā helu GSM mai 300 a ʻoi aku ma mua o 900. Hana ʻia kēia mau mea no nā kūlana koʻikoʻi.
2. Kūkulu ʻana: Kahi i kūkulu ʻia ai ke kūpaʻa
He mea koʻikoʻi like nā ʻokoʻa o ke kūkulu ʻana. Hoʻohana nā kāwele māmā i nā ʻāpana pelu maʻalahi a i ʻole i hoʻopaʻa ʻia i ka wela e haehae maʻalahi i lalo o ke kaomi, ʻoiai ʻo nā mana hana kaumaha e hōʻike ana i nā ʻāpana i hoʻoikaika ʻia e ke kaula e hoʻolaha like i ke kaumaha. ʻO nā grommets ma nā hiʻohiʻona māmā he plastik a me ka metala māmā, i hoʻokaʻawale ʻia ma kahi o hoʻokahi mika ke kaʻawale, a hiki ke huki i waho me ka ʻole o ka ikaika nui. ʻO nā kāwele kaumaha, ma ke ʻano ʻē aʻe, hoʻohana i nā grommets keleawe pale i ka popo a i ʻole ke kila kila i hoʻokaʻawale ʻia i kēlā me kēia 45 a 60 kenimika, me nā hoʻoikaika kihi e pale aku i ka haehae ʻana. Hōʻike pū nā humuhumu i kahi moʻolelo: hilinaʻi nā kāwele māmā i ka humuhumu wela a i ʻole ka humuhumu maʻamau e kahe pinepine ana ma hope o ka hōʻike ʻana o UV, ʻoiai ʻo nā kāwele vinyl kaumaha e hoʻohana i nā humuhumu humuhumu kiʻekiʻe e paʻa mau ana i ka wai no nā makahiki.
3.Hana: ʻO ka ʻokoʻa maoli o ke ao
I ka wā e pili ana i ka pale wai, hana maikaʻi nā kāpeti māmā i ka wā hou, akā ʻo nā humuhumu a me nā grommets he mau wahi nāwaliwali e alakaʻi pinepine ai i nā leaka. ʻAʻole komo loa nā kāpeti PVC hana kaumaha, a ʻo kā lākou mau humuhumu i hoʻopaʻa ʻia e hōʻoiaʻiʻo i ka paʻa wai no ka manawa lōʻihi; hāʻawi nā kāpeti canvas i kahi kahua waena—pale wai a hanu, e kūpono ana iā lākou no nā hana kahi e pono ai ka ea.
ʻO ke kū'ē ʻana i ka UV kekahi laina hoʻokaʻawale nui. ʻAʻole lawa nā mea pale UV i nā pāpale polyethylene maʻamau a lilo pinepine i mea palupalu i loko o 6 a 12 mau mahina o ka hōʻike pololei ʻana i ka lā. Eia nō naʻe, aia nā pāpale vinyl ʻoihana i nā mea hoʻopaʻa UV a hiki ke mau no 5 a 10 mau makahiki ma waho, ʻoiai ʻo ka canvas i mālama ʻia e hāʻawi i kahi 3 a 5 mau makahiki maikaʻi.
ʻOkoʻa nō hoʻi ke ahonui i ka mahana. Hana pono nā taps māmā ma waena o –20°C a me 60°C (–4°F a i 140°F), akā lilo i paʻakikī i nā kūlana hau. Kūpaʻa nā taps PVC hana kaumaha i kahi ākea ākea, mai –30°C a i 70°C (–22°F a i 158°F), a he nui nā mea i hoʻokō i nā kūlana pale ahi—he hiʻohiʻona palekana koʻikoʻi no ka hoʻohana ʻoihana.
Hoʻopoina pinepine ʻia ka hanu ʻana akā he mea nui loa ia. ʻAʻole hiki ke hanu ʻia nā tarp māmā, e hoʻopaʻa ana i ka makū ma lalo a hiki ke hoʻoulu i ka ʻōpala a i ʻole ka ʻōpala. Hiki ke hanu maoli nā tarp canvas kaumaha, e lilo ia i koho makemake ʻia no ka uhi ʻana i nā lako, ka lāʻau, a i ʻole ka mauʻu kahi e pono ai ka ea. ʻO nā tarp vinyl, ʻoiai ʻaʻole hiki ke hanu ʻia, ʻoi aku ka maikaʻi i ka wā e pono ai ka pale wai piha.
4. Ka Laina Lalo
He koho kūpono ke kumukūʻai o nā pāpale PE māmā no nā pono pōkole a pōkole. No ka ʻike ʻana i waho no ka manawa lōʻihi, nā kūlana makani ikaika, a i ʻole nā noi e pono ai ke mālama ʻana i ka palekana, hāʻawi nā pāpale PVC kaumaha a i ʻole nā pāpale canvas i mālama ʻia i ka lōʻihi a me ka hana maikaʻi loa. ʻO ke koho ʻana i ka pāpale kūpono ʻaʻole ia e pili ana i ka nui wale nō—e pili ana i ka hoʻomaopopo ʻana i ka mānoanoa o ka mil, GSM, a me nā kikoʻī kūkulu e hoʻoholo ai inā mau kou uhi i hoʻokahi kau a i ʻole he ʻumi makahiki.
