How to choose spray pump, to avoid rusty spring Technical Analysis: Spray pump spring technical analysis (1) a. How to choose the spray pump, to avoid the rusty spring Technical Analysis: Cosmetic manufacturers in the market have encountered or been concerned about the spray pump spring rust problem; a bottle of beautifully packaged, formula unique cosmetic because of a spray Spring pump rust after a period of time, resulting in completely contaminated cosmetics solution can not be used, can only be scrapped, which can not be a deadly blow to the cosmetics manufacturers. Therefore, the cosmetics factory in the purchase of spray pumps are particularly worried about the spray pump spring rust problem, but the various cosmetics factory can not be very professional to quickly and accurately determine the quality of the spray pump spring can only be suspected of hearing the spray pump Production suppliers continue to guarantee, re-guarantee. . . There are even cosmetic manufacturers direct use of the next best policy: the spray pump production suppliers pledged payment, exhausted spray pump and then settled payment; do not know this kind of precautionary measures, make up for the aftermath of the direct result of the consequences: once the spray There is a problem with the pump spring. The loss of the cosmetics factory is far beyond the value of a batch of spray pumps. The impact of the brand can not be seen, the loss of dealer confidence and so on is the real huge loss. So how to buy spray pump, to avoid spring rust? How to quickly and accurately test the spray pump spring when it is accepted, it has been determined that it will not rust? China Cosmetics spray pump network combined with the major outstanding spray pump manufacturers, the quality of the spray pump spring to resolve: 1. How to choose the material of the spray pump spring? There are N kinds of materials suitable for springs in the existing steel wire market. However, due to the ever-changing cosmetic formula, the spring material of the spray pump must be required to have good acid and alkali resistance. Spray pump spring commonly used in the domestic market, the main material is: SUS304H; that is not suitable for all SUS304H cosmetic solution? The answer is: NO; SUS304H have a certain range of use; to hand sanitizer as an example: due to the hand sanitizer formula added bacteria removal factor, the liquid PH value was weakly acidic, the general PH: 6-7 between the basic range of SUS304H spring use : PH5.5 above. That other unique formula cosmetics and what kind of material spray pump it? SUS304H steel market more excellent acid and alkali resistant materials are: SUS316L; to dandruff shampoo as an example: due to dandruff shampoo formula with ZPT, SUS316L spring dandruff shampoo water is normal Use range: ZPT content of about 5; should be said: the use of SUS316L spring spray pump to meet the 99 shampoo / shower gel solution of acid (alkali) (spring corrosion) requirements. 2. A variety of acid-base material of the spring cost: on the market part of the spray pump manufacturers use SUS304, instead of SUS304H; SUS304 material containing Ni content of 5-7, its acid-base far worse than SUS304H, The price is also far worse than SUS304H. Spray pumps using the SUS304 spring can easily rust the spring when the cosmetic formulation is slightly altered. There are even spray pump manufacturers to use direct carbon steel spray pump spring, this spring need not soak any solution, are prone to rust in the humid air. In this remind all major cosmetics manufacturers purchase spray pump spring must be based on actual use to avoid the use of carbon steel and other corrosion-resistant materials made of spray pump spring. For SUS304H, which contains Ni content of 8 or more; the use of SUS304H spring spray pump basically meet the general formula of hand sanitizer, shampoo, shower gel, detergent, oil agent, jelly water and other products; SUS304H price Moderate; it is precisely because of its better acid and alkali resistance and the right price, SUS304H was widely used by major spray pump manufacturers. For SUS316L, the content of Ni is higher than that of SUS304H, and the content of Ni is up to 12. SUS316L spring spray pump can meet the acid and alkali resistance (spring corrosion resistance) requirement of 99 shampoo / body wash solution. However, The price is high, as measured by the market supply chain, SUS316L steel production and procurement cycle is relatively long; generally: 30-35 days. So there is a stable use of SUS316L spring spray pump manufacturers need to prepare in advance stocking. Commonly used SUS316L spring spray pump manufacturers, including Japan's P & G, Unilever and other large cosmetic manufacturers. 3. The most intuitive and accurate judgment of the spring is the use of: SUS304 or SUS304H or SUS316L method is: Sampling steel samples submitted by the Institute for the analysis of the material comparison; focus on the content of Ni on it. Major cosmetic manufacturers according to the actual cost of the purchase, compared to the cost-effective spray pump and composition of their own cosmetics to a rough analysis of the choice of SUS304H spring spray pump or SUS316L spring spray pump.
