It is well known that the salt spray test in salt spray test chamber can be used for neutral salt spray, acid salt spray and copper accelerated vinegar instinct salt spray test. As for the preparation of salt solution, Xiaobian prepares for you: About the salt spray test chamber acetate solution preparation 1 first analyze the pure sodium chloride dissolved in the weathering test equipment purified water, the concentration is (50 ± 10) g / L; The Plastic Bottle is divided into sections based on a variety of common bottle characteristics including color,shape and material. The plastic bottle can be used for as container of cosmetics,daily-use chemical products and gardening products etc. It's mainly produced by blow molding process from one of the following PET(polyethylene terephthalate) and HDPE(high density polyethylene) plastic,and by injecting machine for acrylic and airless bottle. Acrylic cosmetic bottles are an incredibly popular method used for the storage of liquid cosmetics and even some powders. More often than not,they are used to store lotion,or a creamy cosmetic liquid,some are also used for perfumes. Airless Container can store creams,serums and gels without contamination,it's usually with matte silver or gold cap,clear body and shiny silver or gold collar. It's great for travel or use at home.

About the salt spray test tank neutral salt solution preparation 1 Analytically pure sodium chloride dissolved in purified water, the concentration is (50 ± 10) g / L;
2 using PH test paper at 25 ° C, the pH of the test solution is 6.5 ~ 7.5;
3 If it is out of range, it can be adjusted by adding analytical hydrochloric acid or sodium hydroxide solution. The prepared solution needs to be filtered before use.
2 then adjust the pH of the solution with acetic acid to a range of 3.1 to 3.3, which is measured using the collected salt spray sample;
3 The pH should be measured at 25 ° C. The prepared solution should be filtered before use.
This chapter is a small series for you to explain the preparation of neutral salt spray, acid salt spray solution, the next chapter continues to provide you with salt spray test chamber copper accelerated acetate solution preparation, please continue to pay attention.
