Environmentally friendly stainless steel passivation liquid
Product overview:
Environmentally friendly stainless steel passivation liquid is newly developed and applicable using the world's leading R&D technology The environmentally friendly passivation liquid for series stainless steel products is used to replace anti-rust oil, anti-rust grease and traditional hexavalent chromium passivation and anti-rust methods to form a dense, dry passivation film on the surface of the workpiece. The function of completely isolating the metal from the corrosive medium prevents direct contact between the metal and the corrosive medium, so that the metal basically stops dissolving and forms a passive state to achieve the effect of preventing corrosion.
Second product advantage:
. Suitable for chromium-free passivation of all stainless steel products in the series.
.The surface appearance, color, gloss, size, etc. of the workpiece will not be changed after passivation. It is simple to operate, convenient to use, economical and practical, and does not require complicated equipment.
. Environmentally friendly, chromium-free, in line with the latest EU standards and does not contain hexavalent chromium components such as chromate. The corrosion resistance is increased by ~ times (according to the - and neutral salt spray test standards), but due to the material, rust spots will begin to appear. Depending on the characteristics, the anti-corrosion effect may be different).
Three recommended uses:
. Widely used in aerospace, mobile communications, glasses, watches, auto parts, precision hardware, medical equipment, food machinery, fasteners, etc.
. Used in stainless steel fastener precision casting cutting, stamping, tapping, wire drawing, welding and other processing products.
Four environmental protection properties:
The passivation liquid does not contain harmful substances and complies with r, r, r environmental protection standards and has passed D, D and other tests.
. Wastewater is treated in a centralized manner and neutralized with alkaline lime water or sodium hydroxide to make the value close to the value before being discharged, which will have no impact on the environment.
5. Packaging and storage:
. This product is packaged in plastic barrels (kg/barrel).
. Store in a ventilated, cool and dry place. The storage temperature does not exceed ℃ and avoid direct sunlight. The validity period is 3 months.
