I ke kūkulu ʻana i nā pā haʻuki i waho a i ʻole i loko, ʻo ke koho ʻana i ka ʻāina kūpono he mea nui. ʻO Silicon PU a me EPDM ʻelua mau mea hoʻohana maʻamau no ka paʻa ʻana o ka hale i kēia manawa, akā ʻokoʻa ko lākou mau hiʻohiʻona a me nā hiʻohiʻona kūpono.
1.ʻAha Silicone PU
ʻO nā pā hale Silicon PU kahi ʻili paʻakikī a elastic i hoʻohui ʻia me ka ʻili maʻemaʻe a me nā kala ʻālohilohi. Hoʻohana pinepine ʻia lākou i nā wahi haʻuki ʻoihana e like me ka basketball, badminton a me ka tennis.
Pōmaikaʻi: ʻAʻahu -pale, UV-pale, lōʻihi-kala paʻa, ʻoluʻolu ka wāwae, kūpono no ka hoʻomaʻamaʻa haʻuki ʻoihana.
Nā hemahema: Nā koi kūkulu kiʻekiʻe a me ke kumu kūʻai kiʻekiʻe; He koʻikoʻi nā koi no ka ʻōnaehana wai.
2. Aha EPDM
Hana ʻia nā ʻaha EPDM me nā ʻāpana ʻōpala, me kahi ʻili palupalu a me ka elasticity maikaʻi. Loaʻa pinepine ia ma nā kahua pāʻani kindergarten a me nā kahua haʻuki leʻaleʻa.
Pōmaikaʻi: Elasticity maikaʻi, palekana kiʻekiʻe, kūpaʻa ikaika, a me ka uku mālama haʻahaʻa.
Nā pōʻino: ʻoi aku ka pōkole o ke ola lawelawe ma mua o ka silicon PU, hiki i ka waihoʻoluʻu ke hele mālie i ka manawa, a haʻahaʻa iki ka hana haʻuki.
Ma keʻano o ka lōʻihi a me ka mālamaʻana i nā kumukūʻai,ʻoi aku ka maopopo o nā pono o ka silicon PU. He ʻeleʻele kona ʻili a he hana kūʻē -kahiko ikaika, hiki ke pale aku i nā kukuna ultraviolet, ka hoʻokomo ʻana i ka wai ua a me ka ʻaʻahu ʻana i kēlā me kēia lā. Hiki i kona ola lawelawe ke hiki i 8 a 10 mau makahiki. Pono ka mālama ʻana i kēlā me kēia lā i ka hoʻomaʻemaʻe maʻamau a me ka holoi ʻana i kekahi manawa me ka wai maʻemaʻe, me ka ʻole o ka hoʻoponopono pinepine ʻana. Ma muli o nā hiʻohiʻona o ka EPDM, nā pilikia e like me ka ʻelemakule a me ka ʻili ʻana, a me ka haki ʻana o ke kāpili e hiki ke loaʻa ke ʻike ʻia i waho no ka manawa lōʻihi. He 5 a 7 makahiki maʻamau kona ola lawelawe, a inā he pōʻino kūloko, pono e hoʻomoe hou ʻia ka ʻāpana holoʻokoʻa, a ʻoi aku ka nui o nā kumukūʻai mālama.
Mai ka hiʻohiʻona o nā hiʻohiʻona kūpono, ʻoi aku ka maikaʻi o ka silicon PU no nā wahi hoʻokūkū ʻoihana a me nā wahi hoʻohana kiʻekiʻe -e like me nā kahua pāʻani kinipōpō maʻamau i nā kula, -nā kahua haʻuki nui i nā kaiāulu, a me nā wahi haʻuki ʻoihana, ʻoi aku ka nui o nā wahi e pono ai ke hoʻokipa i nā pāʻani kinipōpō like ʻole e like me ka pōʻaleʻa, pōʻaleʻa. ʻOi aku ka maikaʻi o ka EPDM no nā wahi hana a nā kamaliʻi a me nā wahi hoʻohana haʻahaʻa -e like me nā kahua pāʻani plastik ma nā kindergarten, nā kahua haʻuki i hoʻopili ʻia i nā wahi pāʻani o nā keiki ma nā kaiāulu noho, a me nā wahi haʻuki leʻaleʻa ma nā paka. ʻOi aku ka maikaʻi o kona palekana maikaʻi a me ke kumu kūʻai mua haʻahaʻa i nā pono o ia mau hiʻohiʻona.
I ka hopena, ʻo ke kī i ke koho ʻana ma waena o ka silicon PU a me ka EPDM aia i ke kaulike ʻana i "nā koi haʻuki, ka hoʻohana pinepine ʻana, nā koi palekana a me nā kumukūʻai kālā". Inā ʻoe e ʻimi nei i ka ʻike haʻuki ʻoihana a me ka lōʻihi -paʻa, ʻoi aku ka maikaʻi o ka silicon PU. Inā ʻoi aku ka manaʻo i ka hoʻopukapuka mua ʻana i ka pale a me ka hoʻomalu palekana, ʻoi aku ka maikaʻi o ka EPDM-. Ma ke koho wale 'ana ma muli o ka ho'onohonoho 'ana a me ka ho'ohana 'ana i kona wahi pono'ī, 'a'ole hiki i ke kahua pā'ani ke ho'okō i nā koi akā ke ho'ohana 'ia ka waiwai no ka wā lō'ihi.
