Cosmetic plastic hose hose high white material in the production of common problems
cosmetic plastic hose manufacturer
( 1) Bubbles in the high white material cosmetic plastic, bubble is often appear problem, mainly by the small bubbles of the diameter of less than 1 mm, occasionally also can appear larger bubbles, the reasons are complex, and main process factors and external factors.
in cosmetic plastic pool kiln relative to non-ferrous materials, high white material liquid cosmetic plastic top and bottom temperature difference is small, the temperature at the bottom of the relatively high, relative viscosity are much lower. Therefore, high white material cosmetic plastic bubble in liquid discharge is much easier, but bubble absorption is much more difficult, this is mainly due to the gas solubility in the cosmetic plastic fluid is inversely proportional to the temperature. Therefore considering high white material in the cosmetic plastic bubble problem, don't ignore bubbles & other; Absorption & throughout; Exclusion effect, take appropriate lower melting temperature, improve the gas solubility in the cosmetic plastic fluid, at the same time control the input method, can make the bubbles are affecting the quality of products the appearance of cosmetic plastic fluid absorption and elimination. It is certainly not the lower the temperature, the better, when the temperature down to a certain degree, the problems will be toward the opposite, not only bubbles can't reduce, there will be stones. In addition, high white material cosmetic plastic production for gas rate and melting rate should also be appropriate control, shoulds not be too high. According to the production experience: larger bubbles or skin bubbles usually has little to do with cosmetic plastic melt system, mostly produced in feed.
( 2) Crystallization of cosmetic plastic crystallization is one of the common defects in production, and is more serious in the high white material cosmetic plastic, often lead to long product is unqualified, caused great losses, should from the cosmetic plastic components in cosmetic plastic production, ingredients, process, production process control and furnace design, both inside and outside factors such as comprehensive consideration, avoid to produce cosmetic plastic crystallization.
