A production system for preparing industrial water reducer

Abstract

The invention discloses a production system for preparing an industrial water reducer. The production system comprises a liquid industrial naphthalene storage tank, a crystallization tower, a distillation tower, an acidification tower, a hydrolysis tower, a first reaction tower, a second reaction tower, a concentrated reaction tower, a pH regulating tower, a third reaction tower, a centrifugal dehydration tower, a drying tower, a high-grade finished product storage tank, a dilution reaction tower, a primary finished product storage tank, a purification reaction tower, a middle-grade finished product storage tank, a water tank, first dosing equipment, second dosing equipment, purifying facilities, and the like. The water reducer product prepared by the system is high in concentration which is higher than 99.9%, the gas content is lower than 2%, the bleeding rate is lower than 0.5%, the difference between initial setting times is 19, and the difference between final setting times is 32, and the alkaline content is lower than 0.5%. Reactants of alcohol polyoxyethylene ether, maleic anhydride, poly-allyl sulfanate sodium, methacrylic acid and the like are added into the second reaction tower, and calcium carbonate and sodium hydroxide are added into a pH regulating tower.

Description

technical field [0001] The invention relates to a production system for preparing industrial water reducers, which belongs to the field of chemical industry. Background technique [0002] Water reducer is one of the concrete admixtures, and it can be divided into common water reducer, high efficiency water reducer and high performance water reducer according to its water reducing and dispersing performance. Ordinary water reducer refers to the admixture that can reduce the amount of mixing water under the condition that the concrete slump is basically the same. Admixture, high-performance water-reducing agent is a high-efficiency water-reducing agent with better performance and can better meet the actual needs. In addition to high-efficiency water-reducing, improving the pore structure and compactness of concrete, it can also control the slump loss of concrete. Better solve the air-entraining, retarding, bleeding and other problems of concrete. Water reducers mainly play t...
