AntiCorrosive Pigments
M'tsogolo mu anticorrosive pigment ndikupeza ma chromate free and heavy metal free pigments ndikupita ku sub-micron ndi nanotechnology anti corrosive pigments ndi zokutira zanzeru zomva dzimbiri. Zovala zanzeru zamtunduwu zimakhala ndi ma microcapsules okhala ndi pH indicator kapena corrosion inhibitor kapena/ndi zodzichiritsa zokha. Chigoba cha microcapsule chimasweka pansi pazikhalidwe za pH. Chizindikiro cha pH chimasintha mtundu ndipo imatulutsidwa kuchokera ku microcapsule pamodzi ndi corrosion inhibitor ndi / kapena kudzichiritsa nokha.
Tsogolo ndi 'ukadaulo wobiriwira' komanso mabungwe osiyanasiyana aboma amapereka kale malangizo awa:
- OSHA PEL akufuna 5 µg/m3 kwa Cr6+ m'malo antchito Feb 27, 2006.
- OSHA adalamula kuti alengeze PEL yatsopano. (zamlengalenga PEL tsopano 20 µg/m3)
- EU Directive 2000/53/EC - Mapeto a Galimoto: Cr6+, Pb, Cd, Hg yoletsedwa pamagalimoto ogulitsidwa pambuyo pa Julayi 1, 2003
- California Air Resources Board (CARB) idavomereza Airborne Toxic Control Measure (ATCM) for Emissions of Cr6+ and Cd from Motor Vehicle and Mobile Equipment Coatings (Automotive Coatings) September 21, 2001.
Anticorrosive pigments zomwe zimatsimikizira malamulowa ndi monga: Calcium Phosphate; Calcium Borosilicate; Calcium silicagel; Magnesium Phosphate.
