Problems solved by technology
[0003] There will be some deficiencies in the production of nitrile latex now. The one is that the process of degassing the nitrile latex will not be thorough enough, resulting in insufficient quality of the product obtained. The second is that the efficiency of the degassing operation is very low. Low, it will be a waste of time, so now there is an urgent need for a degassing device for nitrile latex that can solve the above problems

Description
technical field [0001] The invention relates to the field related to chemical production, in particular to a degassing device for nitrile latex. Background technique [0002] Carboxylated nitrile latex is produced by emulsion polymerization with butadiene and styrene plus a small amount of carboxylic acid and other additives. The introduction of carboxyl groups increases the polarity of the latex and improves the bonding performance. It is used as a papermaking adhesive. It is suitable for surface and bottom coating and bonding of decorative base paper, wear-resistant paper, medium and high-grade art paper, white board paper, cardboard, cardboard paper, etc. Excellent paper-making adhesives must have good bonding strength to improve the surface strength of coated paper. When preparing coatings with high solid content, the viscosity should not be too high, and they must have good leveling properties after coating to improve the surface strength of coated paper. The glossines...
