Чӣ ҳастанд ба three types of water reducing agents with different water reducing effects?
According to the effect of water-reducing agents, they can be divided into the following three categories: (1) ordinary water-reducing agent, инчунин бо номи пластификатор маълум аст, коэффициенти об-кашй аз он кам нест 8%, and its main component is lignin sulfonate; (2) агенти кам-махсули об, инчунин бо номи суперпластификатор маълум аст, its water reduction rate is not less than 14%, and its main component is represented by tea water-reducing agent; (3) high-performance superplasticizer, its water reduction rate is not less than 25%, the polycarboxylic acid series суперпластикизатор is regarded as a representative.
What are the five main types of new efficient water reducing agents?
(1) Polycarboxylic acid series of water reducing agent: polycarboxylic acid type of water reducer molecules have a lot of chains. In the main chain there are some strong polar anion and the surface of the electrical layer combined together, which forms a hydrated film. Due to the above mentioned, it not only enhances the adsorption between molecules but also produces spatial steric resistance, and so it has a good plasticizing effect. Аммо, this kind of water-reducing agent is very expensive, so its application is limited to some extent. Дар айни ҳол, the polycarboxylate based superplasticizer with the comprehensive efficiency and high performance is the best water reducing agent.
(2) Naphthalene series efficient superplasticizer: naphthalene series efficient superplasticizer has electrostatic repulsion effect and molecular mutual repulsion between electric charges. Due to the certain decomposition on the cement in the hydration process of its own flocculation, the free water contained in it can be pushed out. Бинобар ин, you can see the water reduction effect is obvious. Дар муқоиса бо суперпластикизатори силсилаи кислотаи поликарбон, superplasticizer силсилаи нафталин дорои технологияи нисбатан баркамол бо нархи паст.
(3) Superplasticizer силсилаи кислотаи аминосулфонӣ: modified amino sulfonic acid series superplasticizer is a non-air-entraining resin type high-efficiency superplasticizer, whose water reduction rate can reach more than 25%, to the concrete workability and durability have significant enhancement. Аммо, арзиши аслии истехсоли суперпластификатори силсилаи кислотаи сульфамикй нисбатан баланд аст. Вақте ки вазни молекулавӣ хеле хурд ё хеле калон аст, боиси хунравии осон аст, сегрегация ва сахтгирй. Дар айни ҳол, the research of this kind of water-reducing agent is mostly effectively reduce the shortcomings in use and expand the market prospect through modifying aminosulfonic acid and dispersing cement particles.
(4) Суперпластификатори тағирёфтаи лигносульфонат: modified lignosulfonate superplasticizer is obtained by modifying lignosulfonate. Сульфонати нави мод-дишудаи лигнин як агенти кам-махсули об мебошад, its water-reducing rate is 1.5 times higher than that of other ordinary water-reducing agents. The hydration heat and collapse degree of cement are changed to effectively ensure the excellent performance of concrete, ва арзиши аслии махсулот кимат аст, ки ба сохтмон мусоид аст.
(5) Агенти гибридии коҳишдиҳандаи об: агенти коҳишдиҳандаи об тавассути омехта кардани сополимери чорумин сополимери пайвандкунандаи акрилат омехта карда мешавад., which contains amino benzene sulfonic acid maleic acid amide and vinyl pyrrole copolymer. And at the same time due to other copolymer containing sulfonic acid and carboxylic acid based combining together, the functions of their different anion and polarity of functionality can be used as a super plasticizer of a variety of polymers and copolymers, and so it can have cement particle effects. Истехсоли суперпластификатори омехта мураккаб аст, ва оптимизатсияи миқдори омехта таҷрибаҳои зиёдеро талаб мекунад.
