  6 Test principle

  corrosive solution is sprayed into the compressed air fog, mist which surrounded the test sample in a test chamber.

  test can be continuous or cycle.

  corrosion resistance of each sample time is defined as the sample appears to corrosion, longer show the better corrosion resistance.

  salt spray corrosion test chamber Technical data

  7 Practice

  1. salt spray me, please turn on the power supply and air compressor, air hose connection.

  2. The pure water or distilled water is added behind cabinets and cabinet inlet, until the low water level light on the panel off date, or can not operate normally.

  3. drain and an exhaust pipe connected, as shown on the previous indicators is on the left.

  4. The isolation tank with water to the plate position, in order to avoid salt spray leakage.

  5. Test solution deployment modulation methods:

  A. overburden, neutral salt spray test (NSS test)

  a. Saline solution using sodium chloride (chemically pure, analytical grade) and distilled or deionized water at a concentration of (5% ± 0.1)% (mass percentage). Atomized liquid collected, in addition to the bezel turned back part, can not be reused;

  b. PH value of salt solution before atomization at 6.5 ~ 7.2 (35 ± 2 ℃) between. The preparation of a salt solution, can be chemically pure solution of dilute hydrochloric acid or sodium hydroxide to adjust the PH value, but still comply with the concentration of a point.

  B. metal cover layer, copper accelerated acetic acid salt spray test (CASS test)

  a. Sodium chloride was dissolved in distilled or deionized water at a concentration of 50 ± 5g / L.

  b. The added to a solution of copper (CuCl2 · 2H2O) chloride at a concentration of 0.26 ± 0.02g / L (i.e., 0.205 ± 0.015g / L anhydrous cupric chloride).

  c. Adding an appropriate amount in a solution of acetic acid salt spray test chamber to ensure the pH value of the liquid collected 3.1 to 3.3. As before spraying the solution pH is 3.0 to 3.1, the pH of the collected solution is generally in the range of 3.1 to 3.3. PH meter with a pH value of the solution was measured, it can also be proofread by the acidity of the read 0.1pH value change of precision pH test paper as a routine test. PH of the solution can be used to adjust the glacial acetic acid or sodium hydroxide.

  d. In order to avoid nozzle clogging, the solution must be filtered before use.

  6. Pour salt brine liquid supplement bottle, automatically filling brine into the laboratory spray tower, so that the drug flow to the salt spray tower.

  7. The wet ball cup water, covered with gauze wet bulb thermometer, wet gauze ball ends cup placed.

  8. Place the specimen or sample on the shelf: display the desired angle in accordance with standard furnishings, such as the standard specimen 130 × 70 (mm) Available 15 degrees, 30 degrees inclined.

  9. Setting the test temperature: according to the desired standard setting (button "▲" to increase, press "▼" to decrease)

  a.NSS, AASS test: the test chamber temperature 35 ℃; saturated air barrel temperature of 37 ℃ (35 ℃ ~ 40 ℃).

  b.CASS test: the test chamber temperature 50 ℃; saturated air barrel temperature of 55 ℃ (50 ℃ ~ 55 ℃).

  10. Setting the test time: 0 ~ 999Hr (H: the time; the key "+" to increase; press "-" to decrease)

  11. Press the power button operation, pre-heating in advance, to reach the set temperature. Note: The need to test and handled with care so as not to damage the cover lid.

  12. Press the spray button:

  a, will be out in front of the open compressor valve, the pressure was adjusted to 0.2 ~ 0.4MPa primary pressure;

  b, the regulator raised pressure of 0.07 ~ 0.17MPa, the pressure gauge can be learned (clockwise to increase, counterclockwise to decrease).

  13. Press the timer button, depending on the timing of the set time.

  14. After the test, according to the order of each switch is turned off.

  15. If the test anomalies, refer judge dysfunction treatment table.

  8 Test preparation

  1, add a little heat sink inside the bottom of the studio distilled or deionized water to prevent chapped aging of the box when heated.

  2, the water seal groove upper box four weeks should be added the right amount of distilled or deionized water, not too full, not too little, to close the lid, the water and salt spray is better not spill.

  3, the air saturator (stainless steel barrels) of added distilled or deionized water before adding water to open (Figure 1) plus the purge valve and saturator valve until the water level for the water glass box 4 / 5 position is appropriate, when added to a predetermined level, it must close the bleed valve while closing the saturator plus valve. Due to long-term testing, saturator water evaporation consumption when lowering the water level to 2/5 should timely pay, to prevent water shortages lead to heating pipes empty roasting, baking bad saturator and internal plus hot components.

  4, check the water storage tanks and the working chamber is connected between the sprayer intact, the good preparation of a salt solution (typically formulated at 5% concentration) was added to the storage tank.

  5, check the box rear exhaust pipe exhaust fog fog conditions; trachea is off, whether at the outlet pass to the sewer; pipeline is blocked; so as not to affect the salt mist emissions.

  6, stand a good connection pipe inside the funnel casing, check and set the funnel between the fog is smooth intact, it does not affect the collection of salt spray settlement.

  7, check the gas source and saturated the connection pipe; gas source connecting pipe with nebulizer is off, to prevent spills or gas supply shortage in the state.

  8, open the lid, the sample is properly placed between the working chamber of the sample holder (away from the surrounding walls 10%), to maintain a certain distance from sample to sample, the sample is exposed surface area & gt; 98%, and then close the cover.

  9 Maintenance and Other Considerations

  1, after the end of each test, you should open oil-water separator switch, the oil and the water put the net, and wipe clean.

  2, if a long-term test shall not saturated the water put the net, during normal use, should periodically replace the water in the saturator.

  3, when the long-term need, if re-do the test, all electrical and respond to water and gas supply systems to make a specific system check, failure to prevent the boot after.

  4, found that the nozzle clogging dirt, promptly remove the nozzle, with alcohol, xylene, or 1: 1 hydrochloric acid wash or superfine wire dredge careful not damage the wall of the nozzle opening, so as not to affect the spray quality.

  the implementation of standards

  The product can meet GB9789-88 "metal corrosion test under organic and other non-metallic covering layer is generally condensation conditions" test requirements.

  11 pressure regulator

  a: inlet pressure regulator from the first stage regulator manually, the general control 2 ~ 4kg / cm2

  b:. Spray pressure by a reducing valve adjusted to 0.5 ~ 1.7kg / cm2, the classification has been adjusted adjusted at the factory, users generally will not need to adjust

  solution preparation program

  solution preparation salt spray test machine

  A. formulated neutral salt spray test machine salt spray solution will analytically pure sodium chloride dissolved in purified water at a concentration of (50 ± 10) g / L. Measured by PH paper test solution at 25 ℃, PH value of 6.5 to 7.5. May be added when out of range of analytical grade hydrochloric acid or sodium hydroxide solution to adjust the preparation of a good solution before use subject to filtering.

  B. acetic acid salt spray test machine - first formulated analytically pure salt spray solution of sodium chloride dissolved in purified water at a concentration of (50 ± 10) g / L, and then the solution was adjusted with acetic acid PH value, so it is within the range of 3.1 to 3.3, the PH value of the collected samples with Salt measured. PH value should be measured at 25 ℃, the prepared solution was filtered before use required.

  C. formulated copper accelerated salt spray test machine acetic acid / salt spray solution

  The first step would be consistent with analytical solution of sodium chloride in compliance with GB6682XX water at a concentration of (50 ± 10) g / L.
