How to make a powder cake

1. Powder cake, also called pressed powder cake, is a common cosmetic, which is mainly used to absorb sebum and sweat excreted by human body. Second, the production method and technological method 1. Firstly, raw materials such as pigments are mixed in a mixer, and then the mixture of adhesive and additive is added. After mixing evenly, the powder is colored, crushed and sieved by a pulverizer, and then it is allowed to stand for several days, and then it is put into a metal plate for press molding to obtain the finished product. Disadvantages: the production environment is dusty and the powder loss is serious, so it is difficult to greatly improve the product appearance quality. The following figure shows the manufacturing process of Method 1: The following figure shows the reference formula of powder cake ingredients 1: The following figure shows the reference formula of powder cake ingredients 2: Method 2: The powder cake is made by powder slurry injection technology. Mix a suitable solvent with the powder to be produced, stir to form slurry, put it into a container, then pump the slurry into an injection machine with a material pump, and then inject it into the box from the injection hole at the bottom of the plastic powder box through an injection nozzle. The upper part of the powder box is sealed by a lower pressing block, which has a certain number of capillary holes and is connected with a vacuum pump through a pipeline. At the same time when the press block closes the box mouth, the vacuum pump operates to suck the solvent in the slurry through these capillary holes. The filter cloth between the compact and the powder cake can not only form patterns on the powder surface, but also filter the solvent without allowing the powder to pass through, so that the solvent phase in the powder slurry is pumped into the solvent recovery bottle, and only the powder phase remains in the powder box. After taking out the compact, it can be assembled after drying for 24 hours.
