168 zinc sealer galvanizing effects of resistance to salt spray sealer sealer manufacturer

Product Manual Product Model: 168 168 galvanized zinc sealer sealer sealer is water soluble, watered, easy operation, low cost, non-silicate and resins, nontoxic, protective film is easy to remove, treated After the workpiece to form a dense layer of protective film, with a strong anti-salt spray (neutral salt spray test up to 72-240 hours). Operation process: 1 open cylinder with pure water, the concentration of 15-20% 2 Temperature: 50-60 ℃ 3 soak 15-25 seconds, and direct drying off after a little dry (strongly recommended not to wash) 4 drying temperature 90-100 ℃ . For about 20 minutes operation process: plating → washing → passivation → 168 closed → drying (do not wash lightly thrown what can be drip dry) → drying → packing (Note: Blue color zinc and zinc closed after The color will be white and yellow respectively point proposal to achieve better color after drying out the light with 168 closed): 1, if too low a concentration of 15-20% will be from color spots, anti-salt spray fall, too high a concentration in the salt spray test prone to white rust (sealer film is not completely cured also prone to white rust) 2 closing film curing time of 72 hours, so to think of the best salt tolerance should be dry After further 72 hours of salt spray test. 3: 168 recommended for dealing with small parts, do not advocate the use in large parts, it is possible to use on a large piece will appear white. Please be careful with caution. Symptom and solution Symptom Causes Remedy 1 Salt concentration is too low a short time appropriate to add 168, but not more than 20%, otherwise the piece two or three days will be white, 2 plated pieces have color shift phenomenon ditto - 3 plated workpiece surface phenomenon was spotted precipitate was filtered fluid replacement or 4 on the first day normal color, over 2-3 days a high concentration of the color white, 2PH value is low 3 low temperature to reduce the temperature of 1 5-15 % 2 (with AR or chemically pure ammonia increase to 11-11.8 PH 3 after raising the temperature 50-60 ℃ 5 salt spray tests are blushing a high temperature air-dried, and second work is not fully cured the temperature should be lowered to 1 The following 80 ℃, 2 piece again after 72 hours of salt spray test for resistance to salt spray capability if requirements are particularly high recommendation by the following methods: After the workpiece 168 after closing with a temperature of about 60 ℃ first air-dried, and then a temperature of 100 ℃ The following heat 10-20 minutes. Attached concentration detection method. Please hydrometer time slot, recording good value, at least once a day to test, add 168 as long as it can be added according to the proportion of the count value, hydrometer values ??generally slotted 1.04-1.06 168 by increasing or decreasing the concentration of the range of values, when it exceeds the value of 1.06 hydrometer, add water, less than 1.04 168. The suggestion to add the ideal packaging in 1.06: 25 kg / barrel Additionally otherwise stated, this Environmental non-toxic products, but water cooking method detection test hexavalent chromium exceeded, because the goods will be reduced to trivalent chromium hexavalent boiling method under conditions of detection. If the customer requires water heating method detection of hexavalent chromium Please be careful with caution.
