ʻO ka laina hoʻoheheʻe pepa pale wai PVC

ʻO nā hiʻohiʻona o nā mea i hoʻopili ʻia (pepa) PVC wai
1. He kiʻekiʻe ka ikaika tensile PVC, ka elongation maikaʻi a me ka liʻiliʻi liʻiliʻi o ka nui o ka wela.
2. Loaʻa iā ia ka weldability maikaʻi, a ua hoʻohui ʻia ka hui me ka metala kumu ma hope o ka welding ea wela.
3. Loaʻa iā ia ka diffusivity mahu wai, maʻalahi ka hoʻokuʻu ʻana i ka condensate, a maʻalahi ka hoʻokuʻu ʻana i ka wai a me ka wai i ke kumu.
4. ʻO ka pale ʻana i ka wā kahiko, ka pale ʻana i ka radiation ultraviolet, ke kūpaʻa kino kino a me ke kū ʻana o ke aʻa.
5. Loaʻa iā ia ka loli maikaʻi ma ka wela haʻahaʻa (- 20 ℃).
6. ʻO ke ola lōʻihi o ka lawelawe (ka hale 25 mau makahiki, ma lalo o ka honua ma mua o 50 mau makahiki) a ʻaʻohe pollution kaiapuni.
7. Hōʻike ka ʻili o ka waihoʻoluʻu i ka radiation ultraviolet, a ʻo ka ili o ka PVC waterproof coiled material e hoʻemi i ka wela a me ka wela haʻahaʻa.
8. ʻO ka hoʻololi maikaʻi a me ka hoʻonui ʻana, ka ikaika tensile kiʻekiʻe, ke kūpaʻa maikaʻi o ka dimensional, ka ikaika mechanical kiʻekiʻe, ke kūpaʻa erosion, ka permeability o ka ʻōnaehana, ka pale ʻana i ka wā, ka laina UV a me ka pale ʻana i ka huahekili.
