Cosmetic plastic hose high white material hose

Cosmetic plastic hose high white material of hose,

cosmetic plastic hose manufacturer

requirements, other performance requirements the same as the ordinary can cosmetic plastic hose, therefore, its composition is mainly composed of sodium calcium cosmetic plastic components, make a few adjustments on the basis of this. The key is to meet the requirements of high whiteness, must be strictly controlled cosmetic plastic fe content. More than cosmetic plastic of iron with iron oxide ( Fe2O3) And ferrous oxide ( FeO) In the form. These two kinds of iron oxide with its content and proportion of different, make the cosmetic plastic into different levels of yellow, yellow, green, blue, are the main factors influencing the colorless cosmetic plastic, especially the ferrous oxide coloring ability is 10 times higher than iron oxide. Therefore, to improve the cosmetic plastic whiteness, it must be in the production process, reduce the cosmetic plastic fe content, as far as possible to reduce impact on cosmetic plastic whiteness. Also, control the introduction of chromium, titanium, vanadium, such as coloring ions. According to the standard generally high white material iron oxide content in cosmetic plastic should be less than 0. 06%. Table 2 - 43 part lists the domestic high white material hose can cosmetic plastic components.

high white material hose composition of SO2, Al2O3 content at 73% ~ 75%, among them the content of Al2O3 is in commonly 1% ~ 2%, low content of cosmetic plastic will be brittle, excessive levels will increase the cost. MgO style of cosmetic plastic melted and forming has certain positive role, but the introduction or poor quality of raw materials, or the price is too high, not specifically introduced in composition design, general into the introduction of other ingredients. High white material plastic hose cosmetics, in addition to ask its visible light permeability good, also requires a certain refractive index, so the basic ingredients and add a small amount of increase the refractive index of ingredients such as BaO, etc. Introduction a small amount of BaO can increase the refractive index, density of cosmetic plastic, luster and chemical stability, and can accelerate cosmetic plastic melt.
