Beijing Tak Department of Science and Technology Development Co., Ltd. HN-A type of oil off Adhesives I. Introduction: This product processing enterprises for glial aromatics present in high vacuum distillation process, the problem of low yield, by HN-A added to the feed off the oil type sizing agents, so that the raw material at a high temperature decomposition of the gum dispersed, polymerization inhibitor, antioxidant in order to achieve the purpose of reducing the distillate outlet gum. The large number of experiments and applications proved to be efficient in the removal of aromatic gum and increase product yield of about 5%. Second, the product physical properties: the appearance of dark red liquid pour point (℃) 0 Density (g / cm3) 0.9-1.0 PH value 5-6 Third, the main role and features: 1, can effectively remove aromatic hydrocarbons, carbon nine, benzene and other philatelic products in the gum; 2, additives to improve product yield 3% -7% (different oils increase the magnitude different); 3, the active ingredient of the agent boiling point above 300 degrees, the normal distillation without additives will bring the product does not affect other indicators stamp products. Fourth, the use of the product: 1, the processing of raw materials to be processed this agent in oil, mix evenly; 2, the agent recommended dosage: 0.5-2 ‰ (mass ratio); 3, according to the specific amount of addition different oil sample in a laboratory experiment to determine, after the sample is applied to the production of which qualified. V. Applications: suitable for aromatic hydrocarbons, carbon nine, benzene and other oil products.
