Суперпластикжуулагчийн судалгааны явцын тойм

Супер хуванцаржуулагч is a kind of concrete admixture, which can improve the workability of concrete, reduce construction energy consumption and improve construction efficiency. In the concrete, water reducing agent is added to the mixture of cement particles to get dispersion effect and to optimize the working performance of cement. Нөхцөлөөр бетоны уналтыг тогтмол байлгах, mixing and subtract agent can greatly reduce the unit water use of concrete mixture, reduce the water cement ratio of concrete, the strength and stability of the reinforced concrete. Or in the concrete workability and strength of the same condition, adding water reducer can reduce the unit of cement, save cement. Гэсэн хэдий ч, the application of superplasticizer in concrete also has some problems, such as the majority of superplasticizer ions being anionic surfactants, lignin sulfonate, naphthalene sulfonate formaldehyde polymer, гэх мэт..

According to the water-reducing effect of бетоны супер хуванцаржуулагч, бетоны супер хуванцаржуулагч can be divided into the following three categories:

(1) Ordinary water-reducing agent, хуванцаржуулагч гэж бас нэрлэдэг, -аас багагүй ус бууруулах хурд нь 8%, the main component is lignin sulfonate;

(2) High-effect water-reducing agent, супер хуванцаржуулагч гэж бас нэрлэдэг, water reduction rate is not less than 14%, the main component is represented by tea water-reducing agent;

(3) High-performance superplasticizer, water reduction rate is not less than 25%, regarding polycarboxylic acid series superplasticizer as a representative.

Одоогоор, the new type of high efficiency water reducing agent has the following five categories:

(1) Поликарбоксилатын супер хуванцаржуулагч (carboxylic acid water reducing agent): poly carboxylic acid system has a lot of chain between the molecules of water reducing agent of some strong polarity in the main chain anions with surface bonded to a piece of electricity. The formation of hydration film can not only enhance the adsorption force between molecules but also produce space steric effect as well as good plasticizing effect. But this water reducer is expensive, which makes its application be limited to some extent, and make it has strong selectivity to defoaming agent and air-entraining agent. Одоогоор, the polycarboxylate superplasticizer with the best comprehensive efficiency is the high performance superplasticizer.

(2) Naphthalene series high-efficient superplasticizer: naphthalene series high-efficient superplasticizer has electrostatic repulsion effect, molecular repulsion between electric charges, just on the cement in the hydration process of its own flocculation has a certain decomposition effect, so that free water drainage it contained would be reduced, and the water reduction effect is obvious. Поликарбоксилын хүчлийн цуврал супер хуванцаржуулагчтай харьцуулахад, нафталин цувралын супер хуванцаржуулагч нь харьцангуй боловсронгуй технологитой бөгөөд хямд үнээр.

(3) Аминосульфоны хүчлийн цуврал супер хуванцаржуулагч: aminosulfonic acid series superplasticizer is a non-air-entraining resin type high-efficiency superplasticizer, the water reduction rate can reach more than 25%, which make the concrete workability and durability have significant enhancement. Гэсэн хэдий ч, сульфамин хүчлийн цуврал супер хуванцаржуулагчийн үйлдвэрлэлийн өртөг харьцангуй өндөр. Молекулын жин хэт бага эсвэл хэт том байх үед, цус алдахад хялбар байдаг, тусгаарлах, хатууруулах. Одоогоор, the research of this kind of water-reducing agent is mostly through modifying aminosulfonic acid and dispersing cement particles, which can effectively reduce the shortcomings in use and expand the market prospect.

(4) Өөрчлөгдсөн лигносульфонатын супер хуванцаржуулагч: modified lignosulfonate superplasticizer is made by modifying lignosulfonate. Шинэ өөрчлөгдсөн лигнин сульфонат нь өндөр үр ашигтай ус бууруулах бодис юм, the water-reducing rate is 1.5 times higher than that of the ordinary water-reducing agent, and the hydration heat and collapse degree of cement are changed to effectively ensure the excellent performance of concrete, мөн үйлдвэрлэлийн өртөг бага, бүтээн байгуулалтад тустай.

(5) Гибрид ус бууруулах бодис: ус бууруулах бодис нь дөрөвдөгч сополимер акрилат залгаастай сополимерыг холих замаар холино., contains amino benzene sulfonic acid maleic acid amide and vinyl pyrrole copolymer, and at the same time other copolymer containing sulfonic acid and carboxylic acid based collection to a piece, thus using the functions of their different anion and polarity of functionality, can be used as a super plasticizer all kinds of polymer and copolymer, thereby interacting with cement particles. Холимог суперпластикжуулагчийн үйлдвэрлэл нь төвөгтэй байдаг, мөн холих хэмжээг оновчтой болгохын тулд маш их туршилт хийх шаардлагатай.
