There are many kinds of bolt surface treatment. The commonly used ones are electroplating, blackening, oxidation, phosphating and non-electrolytic zinc coating treatment. However, electroplated fasteners account for a large proportion in the actual use of fasteners. Especially in automobiles, tractors, household appliances, instruments and meters, aerospace, communications and other industries and fields are more widely used. However, for threaded fasteners, it is not only required to have certain anticorrosion ability in use, but also to ensure the interchangeability of threads, which can also be called the screw property here. In order to meet the dual performance of "anti-corrosion" and "interchangeability" of threaded fasteners, it is necessary to establish special electroplating standard.

Product function
Lactobionic acid (cas 96-82-2) has whitening, moisturizing and anti-aging effects. It is suitable for the repair and maintenance of dry skin and sensitive skin. Lactobionic acid is formed by the condensation of gluconic acid and galactose. The rich molecules in it have a good moisturizing effect. It can also effectively remove aging keratinocytes and promote regeneration. , At the same time, it can resist free radicals and promote the synthesis of collagen.
Product efficacy
Lactobionic acid (cas 96-82-2) can reduce the cohesive force between stratum corneum somatic cells, accelerate the fall of fragile stratum corneum somatic cells, increase the rate of basal metabolism of squamous epithelial cells, promote skin upgrading, and make squamous epithelium Cells are sorted more neatly, and the stratum corneum is thinner, so it is getting smoother and more delicate.
Lactobionic acid (cas 96-82-2) can also make the keratinized blockage around the skin pores easy to fall off, unblock the hair follicle tube, and reasonably avoid the blockage of the skin pores. When lactobionic acid acts on the dermis, it can stimulate the proliferation and reordering of hyaluronic acid, mucopolysaccharides, collagen powder and elastic chemical fibers, so that the moisture content of the skin is increased, and the skin becomes tighter and stretches, wrinkles and wrinkles are registered. The pleats will also be lowered.Moisturizing Raw Materials suppliers
