Summary. Magnesite cement is a gas-hard cementitious material, and the particularity of the greenhouse environment requires the magnesite greenhouse bracket to have good water resistance, that is, the strength is not reduced in the environment of high temperature and humidity for a long time; At the same time, the magnesium chloride in magnesite cement is harmful to crops, so it is required that the magnesite greenhouse support must not return to halogen.

Magnesite cement is a gas-hard cementitious material, and the particularity of the greenhouse environment requires the magnesite greenhouse support to have good water resistance, that is, the strength of the magnesite greenhouse support is not reduced in the high temperature and high humidity environment during the long lifting period; At the same time, the magnesium chloride in magnesite cement is harmful to crops, so it is required that the magnesite greenhouse support must not return to halogen.

Jinan Magato hand-rolled greenhouse skeleton.

Good strength: In the production process of the hand-rolled greenhouse skeleton, the glass fiber cloth is distributed in parallel and regular, and the surface layer is outside, the fiber reinforcement effect is good, the strength is high, and the snow resistance is good, especially suitable for use in areas with little snow and wind in the north. Due to the low requirements for the fluidity of the slurry, the requirements for the activity of magnesium oxide are not high, and the high activity can be slightly higher than the molar ratio, and the inorganic filler can also be added to adjust the fluidity of the slurry, and the slurry with low activity can also be used.

Fast curing: The hand-rolled greenhouse skeleton has low requirements for slurry fluidity, and the slurry is thicker, so the curing is fast.

Poor water resistance: because the inside of the hand-rolled greenhouse skeleton is foam, there is only a thin layer of magnesium cement on the outside, and there is no plastic cloth coating outside during the curing process, the water evaporates quickly, and there are many capillaries, so the water resistance is not good.

Poor flexibility: due to the fact that the hand-rolled production is relatively low compared to the enema production, the fluidity requirements of the slurry are low, and under certain conditions, the molar ratio of magnesium oxide to magnesium chloride is high, and the product produced has good strength, but the flexibility is poor and the wind resistance is poor.

The site requirements are small, but the production efficiency is low. Hand-rolled production is a manual operation, which does not require machinery, and has little requirements for the production site, but the efficiency is relatively low. Spring and autumn sheds are generally 120-150m person-days, and winter greenhouses are generally 80-120m person-days.

The existing greenhouse mostly adopts earth wall to do thermal insulation wall, and the disadvantages of this thermal insulation mode are as follows: 1. It covers a large area, and the thickness of general thermal insulation wall is between 3-4 meters. 2. The amount of construction is large, and large machinery needs to be used.

3. The heating in the shed is slow, and the soil wall will absorb part of the heat, which affects the thermal insulation effect of the greenhouse. 4. Troublesome maintenance, insulated wall is not resistant to rain erosion, and the service life is short.

The advantages of the new thermal insulation board wall greenhouse produced by Jinan Magato are as follows:

1. The construction is convenient, no large-scale mechanical operation is required, and the construction can be pasted on site, and the installation is convenient.

2. The thickness of the insulation board wall is 30-40 cm, and the floor area is small.

3. Excellent performance, the new insulation board has quite good elasticity and tensile resistance, will not be crushed by frozen soil, and is suitable for use in cold areas in the north.

4. The thermal insulation effect is good, and the new insulation board wall is filled with polystyrene foam board, which has excellent thermal insulation performance.

5. Long life, the insulation board wall is made of magnesite composite cementitious material on both sides, the surface is hard and firm, the bearing capacity per square is up to 350 kg, it has excellent wind resistance and impact resistance, and the service life can reach more than 30 years.

The insulation board wall has the advantages of low quality, convenient construction, small floor area, good thermal insulation effect, excellent performance and long service life. The thermal insulation board wall greenhouse can be widely used in the planting and seedling cultivation of vegetables, flowers and fruits.

The life of the magnesite greenhouse skeleton is determined by four factors:

1. The formula of magnesite cement is not reasonable (a reasonable formula can make magnesite gel into a relatively stable 518 phase crystal);

2. The reinforcing material added to the magnesite greenhouse rod - glass cloth, is not medium alkali (high alkali glass cloth begins to break after 6 months).

3. The magnesite greenhouse rod produced is not waterproof (magnesite cement is not water-resistant).

4. The process and maintenance of magnesite greenhouse rod production must be standardized.

A well-done magnesite greenhouse pole has been useful for 8 years. More than 15 years is a theoretical projection, and as far as I know, there are no examples that have actually been used for more than 15 years.

The magnesite greenhouse pole that is not done well will begin to collapse in half a year.

Magnesite greenhouse, that is, magnesite cement product, because the preparation of magnesite cement is more difficult and not easy to master, so it is necessary to be cautious to make magnesite greenhouse.

It's all a lie, and the cost performance is not as good as a bamboo pole.

Repentance magnesite greenhouse skeleton is an ideal shed for melon vegetables, flowers, forest fruits, breeding and other industries, with light weight, strong durability, no environmental pollution, not subject to geography, temperature conditions and other advantages.

The greenhouse adopts a rectangular design in the broken direction, and the overall structure is reasonable. It has good wind resistance and external load resistance, and its service life can reach more than 10 years. It has a good lighting effect, good thermal insulation performance, large operating space, and can be cultivated with multi-layer thermal insulation.

Magnesite greenhouse bracket is favored by users because of its affordability, high yield and high income, durability, spaciousness and convenience, and it is also a new type of shed for the current greenhouse production to start a new type of shed to increase income, increase efficiency and upgrade.

The new re-excavation and reintegration material greenhouse skeleton overcomes the shortcomings of the original bamboo, wood and steel processing and production support. It solves a series of problems such as the shortage of greenhouse materials, short service life, time-consuming assembly, labor-intensive, easy rust, rot, high cost, and poor lighting effect. The temperature in the new shed is 4 -8 ° higher than that of the old shed.

Due to the long-term use of magnesite greenhouse bracket in high temperature and high humidity environment, the water resistance of the product must be good. At the same time, because brine is toxic to crops and will cause vegetable leaves to rot and deteriorate, it must be modified.

The magnesite greenhouse bracket can use two modifiers of our company, GX-1 and GX-4. 1. It can significantly improve the water resistance of the greenhouse skeleton, and the strength will not be reduced even if it is used carefully in a high-humidity environment for a long time; 4. It can prevent halogen return, significantly improve the toughness and strength of the product, and reduce the water absorption rate of the product.

After using our company's modifiers, the product performance is as follows:

Physicochemical characteristics of the product:

GX-1 : Light green liquid, density, pH 2 3.

GX-4 : Black liquid, density, pH 11 12.

Dosage: The dosage of GX-1 is magnesium powder (to control the setting time, improve the strength and water resistance).

The dosage of GX-4 is magnesium powder (improve material dispersibility, resist halogen reflux and toughening).

How to use: Add brine to the mixer, start the mixer, and add 1 modifier at the same time;

Then add the lightly burned magnesium oxide and inorganic filler to the mixer and stir, add 4 modifiers, and stir for 3 minutes; Finally, add sawdust and continue to stir until the material is even.

The whole stirring process takes about 10 minutes.
