Ko te mita rere hikohiko he taputapu e whakamahi ana i te mātāpono o te whakaawe hikohiko hei ine i te rere o te wai kawe hiko i runga i te kaha hiko e puta ana i te wā e haere ana te wai kawe hiko mā roto i tētahi papa aukume o waho.
Nā, me pēhea te whiriwhiri i te arai o roto me te rauemi hiko?
Kōwhiringa Rauemi Arai
■ Neoprene (CR):
He pūmua i hangaia mā te whakakotahitanga o te pūmua chloroprene. Kei roto i tēnei ngota rapa ngā ngota chlorine, nō reira, ki te whakatauritea ki ētahi atu rapa whānui: He tino pai te ārai-waikura, te ārai-ozone, te kore e mura, te tineia i muri i te ahi, te ātete ki te hinu, te ātete ki te whakarewa, te ātete ki te waikawa me te kawakore, me te ātete ki te koroheketanga me te hau. He pai te piri me ētahi atu painga.
✔ He pai mō te ine i te rere o te wai puna, te wai ahumahi, te wai moana me ētahi atu taputapu.
■ Rapa polyurethane (PU):
Ka whakapūhuitia ki te polyester (polyether rānei) me te matū ngako diisocyanamide. He pai ōna painga o te pakeketanga teitei, te kaha pai, te ngāwari teitei, te ātete ki te kakahu, te ātete ki te haehae, te ātete ki te koroheketanga, te ātete ki te ozone, te ātete ki te irahiko me te kawe hiko pai.
✔ He pai mō te ine i te rere o ngā mea paru pērā i te penupenu me te penupenu one.
■Polytetrafluoroethylene (P4-PTFE)
He pūhui tēnei i hangaia mā te whakakotahitanga o te tetrafluoroethylene hei monomer. He mā te ware pi, he mārama, he ātete ki te wera, he ātete ki te makariri, ā, ka taea te whakamahi i roto i te -180 ~ 260°C mō te wā roa. He āhuatanga o tēnei rauemi ko te ātete ki te waikawa me te kawakore, te ātete ki ngā whakarewa waro, te ātete ki te waikawa hauwaiwai kohua, te waikawa whanariki, te wai regia, me te waikura kawakore kukū.
✔ Ka taea te whakamahi mō te wai tote waikawa me te wai tote kawakore.
■Polyperfluoroethylene propylene (F46-FEP)
He tino pai te pumau matū me te ātete ki te hihi, ā, he kore e mura, he pai hoki ngā āhuatanga hiko me ngā āhuatanga miihini. He rite ōna āhuatanga matū ki te polytetrafluoroethylene, ā, he kaha te kaha ki te kume me te kume i te polytetrafluoroethylene.
✔ Ka taea te whakamahi mō te wai tote waikawa me te wai tote kawakore.
■Ko te Copolymer o te tetrafluoroethylene me te perfluorocarbon mā te vinyl ether (PFA)
He rite tonu ngā āhuatanga matū o te rauemi arai mō te mita rere hikohiko ki te F46, ā, he pai ake te kaha kume i te F46.
✔Ka taea te whakamahi mō te wai tote waikawa me te wai tote kawakore.
Kōwhiringa Rauemi Hiko
| 316L | He pai mō te wai para o ngā whare, ngā wai para o ngā ahumahi, te wai puna, ngā wai para o ngā tāone, me ētahi atu, me ngā wai tote waikawa-pūtake waikura ngoikore. |
| Hāteloi (HB) | He pai mō ngā waikawa kore-waikura pērā i te waikawa hauwaiora (iti iho i te 10%). Te hauwaiora konutai (iti iho i te 50%) te otinga hauwaiora konutai kawakore o ngā kukū katoa. Te waikawa whākawa, te waikawa waro rānei, me ētahi atu, engari kāore e pai te waikawa hauota. |
| Hāteloi (HC) | He waikawa whakaranu me te wairewa whakaranu o te waikawa chromic me te waikawa whanariki. Ngā tote whakahāweawe pērā i te Fe+++, Cu++, te wai moana, te waikawa phosphoric, ngā waikawa waro, me ētahi atu, engari kāore i te pai mō te waikawa hauwaihaumāota. |
| Taitānia (Ti) | E pā ana ki ngā pūhaumāota (pērā i te konutai pūhaumāota/konupūmā pūhaumāota/konupūmā pūhaumāota/pūhaumāota ferric/pūhaumāota ammonium/pūhaumāota konumohe, me ētahi atu), ngā tote (pērā i te tote konutai, te tote ammonia, te hypofluorite, te tote pāhare pākawa, te wai moana), te waikawa hauota (engari kāore i te whakaurua te waikawa hauota paowa), ngā kawakore me te kukū ≤50% i te pāmahana rūma (te pāhare pākawa, te konutai pūhaumāota, te pāhare pākawa barium, me ētahi atu) engari kāore e pā ana ki: te waikawa hauwaiora, te waikawa whanariki, te waikawa phosphoric, te waikawa hauwaiora, me ētahi atu. |
| Irahiko Tantalum (Ta) | He pai mō te waikawa hauwaiora (kukū ≤ 40%), te waikawa whanariki waimeha me te waikawa whanariki kukū (haunga te waikawa hauota e paowa ana). E pā ana ki te hauhā hauota, te hauhā konutai, te waikawa hypofluorus, te waikawa hauwaiora bromic, te konutai cyanide, te acetate mata, te waikawa hauota (tae atu ki te waikawa hauota e paowa ana) me te aqua regia he iti iho i te 80°C te pāmahana. Engari kāore tēnei rauemi hiko e pai mō te kawakore, te waikawa hauwaiora, te wai. |
