ስለ ኮንክሪት የውሃ ቅነሳ ወኪል ሁሉንም ዓይነት ይገምግሙ

ምንድን ናቸው የ 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) የተለመደው የውሃ ቅነሳ ወኪል, ፕላስቲከር በመባልም ይታወቃል, የውሃ ቅነሳ መጠኑ ያነሰ አይደለም 8%, and its main component is lignin sulfonate; (2) ከፍተኛ-ውጤታማ ውሃ-የሚቀንስ ወኪል, ሱፐርፕላስቲከር በመባልም ይታወቃል, 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 ሱፐርፕላስቲከር 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. ቢሆንም, this kind of water-reducing agent is very expensive, so its application is limited to some extent. በአሁኑ ጊዜ, 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. ስለዚህ, you can see the water reduction effect is obvious. ከ polycarboxylic acid series superplasticizer ጋር ሲነጻጸር, naphthalene series superplasticizer በዝቅተኛ ዋጋ በአንጻራዊነት የበሰለ ቴክኖሎጂ አለው።.

(3) አሚኖሶልፎኒክ አሲድ ተከታታይ ሱፐርፕላስቲከር: 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. ቢሆንም, የሰልፋሚክ አሲድ ተከታታይ ሱፐርፕላስቲከር የማምረት ዋጋ በአንጻራዊነት ከፍተኛ ነው።. ሞለኪውላዊ ክብደቱ በጣም ትንሽ ወይም በጣም ትልቅ በሚሆንበት ጊዜ, የደም መፍሰስ መንስኤ ቀላል ነው, መለያየት እና ማጠንከሪያ. በአሁኑ ጊዜ, 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) የተሻሻለ ሊንጎሶልፎኔት ሱፐርፕላስቲከር: modified lignosulfonate superplasticizer is obtained by modifying lignosulfonate. አዲሱ የተሻሻለው lignin sulfonate ከፍተኛ ቅልጥፍና ያለው ውሃ የሚቀንስ ወኪል ነው።, 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, እና የምርት ዋጋው ዝቅተኛ ነው, ለግንባታ ምቹ የሆነ.

(5) ድብልቅ ውሃ የሚቀንስ ወኪል: የውሃ ቅነሳ ወኪል ኳተርንሪ ኮፖሊመር acrylate graft copolymer በማደባለቅ ነው., 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. የተደባለቀ ሱፐርፕላስቲከርን ማምረት ውስብስብ ነው, እና ድብልቅ መጠን ማመቻቸት ብዙ ሙከራዎችን ይፈልጋል.
