Which is better for powdered concrete sealant curing agent 50

When choosing an epoxy adhesive, a number of factors should be considered. Here are some small experiences that I hope will help you. As a high-performance, high-value-added adhesive, epoxy resin adhesive is highly valued by the industry, but at the same time, counterfeit and shoddy products are often patronized.

Therefore, we can identify it by the following chemical methods. The first method: dissolve the sample in sulfuric acid, then add concentrated nitric acid, and pour a large amount of sodium hydroxide solution, if it is yellow, it is generally epoxy resin.

The second type: drop 5 drops of concentrated nitric acid on the resin adhesive film, move the reactant into the test tube after a few minutes, add 6ml of acetone and then add potassium hydroxide ethanol solution to make it alkaline, if it turns from red to purple, it indicates that it contains epoxy resin glue containing bisphenol A type, this method is also intuitive; Method 3: Take....

The main ingredient of the powder concrete sealing curing agent is acidic magnesium fluorosilicate. Magnesium fluorosilicate can improve the hardness and strength of concrete, and can also be used for fluoride weathering treatment on the surface of silica buildings, ceramic manufacturing, fabric insect resistance, etc.

There are a lot of them now, as long as they meet, most of them are the same.

Guangdong Yifeng building materials ****, the most cost-effective high penetration capacity, high cost performance. Seeking truth from facts and getting it right is the best. The advantages are: complete reaction, uniform permeation, deep penetration.

I have used Guangdong Yifeng building materials ****, not bad.

A: Yes, there are both liquid and powdered concrete sealing curing agents on the market today. The advantages of liquid concrete sealant curing agents are:

The reaction is complete, the penetration is uniform, and the penetration is deep. The disadvantage is: inconvenient transportation.

The advantage of powdered concrete sealant curing agent is that it is easy to transport because it is solid. But the disadvantages are:

The reaction is uneven, and it is inconvenient to mix water on the spot. In addition, the solidifying agent of powdered concrete sealant is toxic and causes great pollution to the environment, and over time, the state will slowly ban this toxic substance. Especially when used on chrome green corundum wear-resistant flooring, the use of powdered concrete sealing curing agent will be more poisoning.

There are already construction brothers who have been poisoned during the construction of powdered concrete sealing and curing agent, please be careful, you may be poisoned.

Nalut concrete sealing curing agent is all liquid, which is a concrete sealing curing agent based on ultra-nano polycarbonate lithium silicate, water-based products, non-toxic and harmless, low-carbon, energy-saving and environmentally friendly.

Here we take Nalut liquid concrete sealing curing agent as an example to explain the nine advantages of concrete sealing curing agent:

1. Nalut concrete sealing and curing agent seals the concrete pores and effectively inhibits external pollutants from entering the concrete capillaries.

2. Concrete sealing curing agent enhances the surface hardness and wear resistance of new and old concrete floors.

3. Concrete sealing curing agent improves the compressive strength of new and old concrete floors.

4. Concrete sealing curing agent resists the erosion of oxides.

5. Concrete sealing curing agent inhibits the erosion of chemical substances.

6. The concrete sealant, curing agent reacts with the chemicals in the concrete, and forms a gel in its capillaries.

7. Concrete sealing and curing agent to prevent concrete from peeling and scattering.

8. Nalut concrete sealing curing agent seals concrete and enhances its strength.

9. The concrete floor of Nalut concrete sealing curing agent after mechanical light collection appears marble luster, and the longer it is used, the better the gloss.

Water-agent concrete sealing curing agent and powder concrete sealing curing agent have their own advantages and benefits, and how to choose them needs to be considered in combination with the use needs of the owner. In terms of general functional attributes, both can effectively improve the mechanical properties of cement flooring and achieve the effects of hardening, dustproof and seepage-proof. The difference is reflected in some subdivisions of performance, and the two form a complementary relationship.

Cronfer concrete sealant curing agent.

The main component of water-agent concrete sealing curing agent is usually alkaline silicic acid compound, which has relatively high environmental protection performance and has a good guarantee for construction safety. Powder concrete sealing curing agent has the advantages of fast hardness improvement and fast construction speed, and can be used in humid environments, which are difficult to replace with water-based materials; However, due to the environmental protection properties of the material itself, we need to do a good job of corresponding protection in actual operation.

Concrete sealant curing agents are widely used in wear-resistant floors. The commonly used processes for wear-resistant flooring are epoxy resin flooring and corundum wear-resistant flooring. Epoxy resin flooring has the characteristics of beauty, dustproof, chemical corrosion resistance, etc., and is widely used; However, the raw materials and construction costs are high, the hardness is poor, and it is easy to be damaged by vehicle machinery and equipment, and generally needs to be maintained for 3 to 5 years, the comprehensive cost is high, and the weather resistance is poor, so it is not suitable for coating in the humid environment underground, and it is not suitable for coating in outdoor places.

Emery wear-resistant floor is a wear-resistant floor with emery or quartz sand and high-grade cement as the main body, which has the advantages of low material and construction cost, and can withstand the wear and tear of various vehicles and mechanical equipment, but its strong alkalinity and porosity cause it to be not resistant to oily substances (will leave traces), can not resist the corrosion of chemicals, and is easily corroded by acid and alkali.

The operation process of the wear-resistant floor of the sealing curing agent: The construction and operation process of the wear-resistant floor of the concrete sealing curing agent is: concrete pouring on the ground - leveling - spreading wear-resistant aggregate and wiping - clean water curing for 7 14 days - ground shrinkage joint cutting - concrete sealing and curing agent soaking - floor maintenance.

What are the key points of sealing curing agent construction? First of all, material requirements: different sealing curing agents have different requirements for construction temperature, time, dosage, operation, etc., and must be familiar with the product instructions of sealing curing agents before construction, and operate according to the requirements of the instructions.

All kinds of sealing curing agents should have the quality requirements of non-toxic, odorless, simple to use, penetration, sealing, and improving the performance of concrete.

Concrete sealing curing agent is a colorless, odorless, non-toxic water-based liquid sealing curing agent, through effective penetration (3-8mm), chemical reaction with concrete, to generate non-expansion and non-shrinkage of stable chemical product calcium hydrated silicate, filling the capillary pores in the concrete, making the whole concrete a dense and solid and dense whole, to achieve hardening, strengthening, anti-wear, dustproof, waterproof, anti-chemical erosion, anti-salt, anti-oil, safe and environmentally friendly solid sealing effect. It also increases the service life of the floor by up to 30 years.

Typical applications for concrete sealant curing agents include floors such as warehouses, factories, shopping malls, shops, schools, food processing plants, and hospitals. It can be used on corundum floor, terrazzo floor, ordinary cement floor and other cement foundation floors.

Now there are many brands of concrete sealing curing agent on the market, there are many high-quality curing agents, Zhongsinuo concrete sealing curing agent is good, after use, the strength, hardness and wear resistance of the ground have been significantly improved, and heavy objects will not be dusty and sandy.
