Nā Pigment AntiCorrosive
Ke au e hiki mai ana ma nā ʻano puaʻa anticorrosive ʻo ka loaʻa ʻana o nā puaʻa manuahi chromate a me nā metala kaumaha a e hele i ke ʻano o ka sub-micron a me ka nanotechnology anti corrosive pigments a me nā uhi akamai me ka corrosion-sensing. Loaʻa i kēia ʻano o nā pale akamai nā microcapsules i loaʻa ka hōʻailona pH a i ʻole ka corrosion inhibitor a/a me nā mea hoʻōla ponoʻī. Ua haki ka pūpū o ka microcapsule ma lalo o nā kūlana pH kumu. Hoʻololi ka hōʻailona pH kala like 'ole a ua hoʻokuʻu ʻia mai ka microcapsule me ka corrosion inhibitor a / a i ʻole nā mea hoʻōla ponoʻī.
ʻO ka 'enehana ʻōmaʻomaʻo' ka wā e hiki mai ana a ua hāʻawi mua nā hui aupuni ʻē aʻe i ke alakaʻi i kēia mau kuhikuhi:
- Ua noi ʻo OSHA PEL i 5 µg/m3 no Cr6+ ma nā wahi hana i ka lā 27 Pepeluali, 2006.
- Ua kauoha ʻo OSHA e hoʻolaha i ka PEL hou. (Aerospace PEL i kēia manawa 20 µg/m3)
- EU Directive 2000/53/EC – Kaʻa Hopena o ke Ola: Cr6+, Pb, Cd, Hg i pāpā ʻia mai nā kaʻa i kūʻai ʻia ma hope o Iulai 1, 2003
- Ua ʻae ʻo California Air Resources Board (CARB) i kahi Airborne Toxic Control Measure (ATCM) no ka hoʻokuʻu ʻana o Cr6+ a me Cd mai nā kaʻa kaʻa a me nā mea paʻa kelepona (Automotive Coatings) Kepakemapa 21, 2001.
ʻO nā pigment anticorrosive ʻo ia ka mea e hōʻoiaʻiʻo nei i kēia mau lula e laʻa: Calcium Phosphate; Calcium Borosilicate; Kāleka silicagel; Magnesium Phosphate.
