Why do the magnesite crafts I make always return to frost and crack?

In fact, the problem is not difficult to solve, but it is not only possible to add modifiers, even if it is to add modifiers, it depends on whether it is an effective modifier, which is not to enhance psychological comfort.

A simple analysis of the causes of frost cracking, first, production at high temperature, magnesite products reaction speed is too fast, excessive heat release, resulting in the surface of the product cracking, which is a very common problem in summer. To solve this problem, we should first consider whether to use a comprehensive GX composite magnesite modifier integrating high temperature anti-halogen, anti-frost, reinforcement and retarding, if a simple single modifier cannot be improved.

Second, handicrafts are often complex in shape, heavy, and not simple flat products, so it is difficult to achieve glass fiber reinforcement, reflecting that the temperature is too high and there is no glass fiber cloth in place to tensile resistance, cracking is easy. This requires workers to remember to pay attention to the laying of glass fiber unequal reinforcing materials during production, which is not a simple "as long as there is glass fiber". These precautions are detailed in the "Jinan Magnesite Technology Forum", such as the way of spreading, attention to detail, etc.

Third, the temperature is too high and the humidity is too low in summer, and it is difficult to ensure the curing process, and it is difficult for magnesite products to fully respond to hardening in advance.

Fourth, the ratio of handicraft production is not adjusted at any time according to changes in the external environment. This problem involves many adjustment methods, which are explained in detail in the "Jinan Magnesite Technology Network" and will not be repeated here. These are the main culprits that lead to the frost cracking of magnesite crafts.

I hope you will prove one by one, if you have not used the GX magnesite composite modifier at all, through the elimination method, you should first use it to see how effective it is, and do not need to consider other aspects for the time being; However, if there are problems in other aspects mentioned, I hope to learn and communicate more on the technology network platform to achieve the best drawbacks.

You should ask the losers.

It depends on the concentration of magnesium chloride and the content activity of magnesium oxide 458868994

The temperature does not rise, the brine is not high, it cannot reach 5 1 8 crystal image, the reaction is slow, not only the return of halogen and cracking, the curing time is slow, and the hardness and quality are not good.

Raising the temperature is number one.

Which specific aspect do you ask? The production process of magnesite handicrafts has been introduced upstairs, and the advantages have the unique strength of magnesite products, rust resistance, pollution-free, easy to spray various colors, bright colors, and strong binding force with a variety of material pigments. . . . Jinan Meichen Building Materials Machinery ****.

Magnesite handicraft production process: raw material selection, proportioning, stirring, molding, molding, curing, mold opening, curing, testing, packaging.

The advantages of magnesite handicrafts are as follows:

1. The production process is simple: the new process of molding has completely changed the conventional method of manual single-piece production of sculpture by knife and axe since ancient times, with less energy consumption and low quality.

2. Excellent performance: magnesite handicrafts have high strength, light weight, no deformation, cold resistance, aging resistance, waterproof, fireproof, mothproof, and corrosion resistance.

3. Sufficient raw materials: magnesium oxide, magnesium chloride and other raw materials used in magnesite handicrafts are abundant in China and low in China; The mixed filler is mostly fly ash, crop straw and other industrial and agricultural wastes, which are inexhaustible and inexhaustible.

4. Small initial investment: magnesite handicrafts do not require complex instruments and equipment, and the initial investment is small, suitable for large, medium and small units and individual production.

5. Good social benefits: The production of magnesite handicrafts saves a lot of sculpture wood, steel and energy for the country, and is a good product for energy saving, environmental protection and waste utilization, which is in line with the national policy orientation.

Not as mysterious as you think, in fact, it is a dead thing, rigorous, diligent, this industry is still relatively easy, first of all, the most basic principle you must understand, you have to have the necessary experimental instruments and a certain chemical foundation, the selection of materials to pay attention to quality, the construction process to have a good attitude. With all of the above, I believe you are a success. Good luck.

You use it every day, eat, wash. Basically, no problem. In ancient times, people would usually soak their chopsticks in water for a day or two. Sometimes it is boiled and then can be used for several years!!

I don't know why. However, if it is a mahogany chopstick, soak it in oil for a few days. Cooking oil will do. Oil prevents rapid water loss.

Magnesite cement itself has many advantages and disadvantages, and these disadvantages need to be improved with modifiers. For example, the common problem of magnesite cement is caused by the proportion of raw materials, regardless of whether the blending is accurate, the phenomenon of returning to halogen and frost will occur more or less, so without adding modifiers, the return to halogen and frost will not only affect the beauty of the product but also affect the quality of the product. Therefore, adding some modifiers can basically overcome these problems and prolong the life of the product.

The magnesite modifier of Shandong Luping Construction Reagent Laboratory is very good! I wish you all a great fortune 201414 the Year of the Horse.

After magnesite cement is cured, magnesite modifier can form a water-repellent film on the inner surface of the product and the capillary pores and cavities inside the product, which prevents the intrusion of water and reduces the erosion of water on the product. At the same time, magnesite modifier contains a considerable amount of surfactant ingredients, which can make magnesium oxide and magnesium chloride fully contact and react in a short time, which makes up for the defect that the slurry stirring time is short and easy to lead to insufficient material mixing under large production capacity. Eliminate product defects caused by excessive water evaporation during the curing process of products, significantly increase the early and long-term strength of products, increase surface and internal compactness, eliminate halogen return and whitening, enhance the hydrophobicity of products, and the activity of combining with CO2, reduce the generation of brucite, increase the generation of magnesium carbonate, and improve stability and strength.

It can effectively promote crystal development, improve crystal stability, fill the intergranular gap, and solve the problem of halogenation from the essence. Effectively promote the reaction speed, shorten the demoulding time, improve the utilization rate of the mold, significantly increase the surface smoothness of the product, eliminate porosity, sand inclusion, etc. Significantly eliminate cracking, mildew, discoloration and other abnormal use methods of process products

The addition amount is 6 8 of the amount of magnesium oxide; Add to the slurry, stir well to give full play to the best effect, the product should be properly covered before demolding, and it is forbidden to be exposed to the sun to prevent water shortage when the product is cured. Scope of application: The products are widely used in various magnesite cement products

Greenhouse skeleton, thermal insulation chicken coop, exterior wall insulation board, corrugated color tile, magnesite manhole cover, fireproof board, ventilation pipe, flower pot and other handicrafts, decorative parts, decorative boards, logistics pallets, packaging boxes, etc.

Add modifier and don't add.

There is definitely a difference in product quality and service life.

I am now using the modifier of Beijing Magnesite Composite Materials Research Institute, the tile brightness is very good, the waterproof is good, the natural life will be long, and their first modifier can solve your problem.

I've been making cakes for three years and every time it's cracked because it's normal. The cracking of the chiffon cake embryo is to imitate the internal gas and egg smell to make it more mellow The square plate will not crack because of the area and thickness

The egg embryo is not eaten directly, every time I apply cream, I will directly use a spatula to cut off the cracked layer on top.

But I see that you bake a little burnt, and the next time you bake it, it's better to add a layer of tin foil when the cake is almost cooked.

And the big fierce hair is not very good, and the next time you bake it, you must put it upside down to cool.

How to flatten or flatten the horns after cutting.

It can be imitated as a taxidermy

In cold weather, blood circulation is poor, elasticity is reduced, and it is easy to cause cracked hands. Lack of pre-land clearance or vitamin A and vitamin E can lead to hand splitting.

The cold wind is clear and the air is dry, and if you don't pay attention to your hands and feet, you will crack, which often occurs in outdoor workers, and is accompanied by bursts of pain. It is best not to get water or other liquids after the tear, otherwise it will be difficult to heal.

There are many ways to do it online, too.
