Magnesite greenhouse bracket has the following advantages:
1 Small investment, no need to build a factory building, small floor space, two-phase and three-phase power supply, and it can be produced by 3 to 5 people.
2 specifications can produce different specifications and models of products, including cylindrical, oval, distance-shaped, shaped, solid, hollow tube and so on.
3. Quick profit does not require high investment and low risk. The market demand is huge and the profit is big.
4 Low cost The cost of using magnesite material to make greenhouse skeleton is lower than that of bamboo and steel.
Flexible operation, convenient transportation and installation, large or small scale and relatively simple transportation and installation.
Raw materials are easy to buy and have a wide range of uses. Raw materials can be bought all over the country.
Magnesite cement is a kind of air-hardening cementitious material, and the particularity of the environment requires that the magnesium greenhouse bracket should have good water resistance, that is, the strength will not decrease under high temperature and high humidity environment for a long time; At the same time, magnesium chloride in magnesite cement is harmful to crops, and it is required that magnesite greenhouse brackets should not return halogen. Through scientific modification technology and reasonable production technology, the above technical problems can be effectively solved.
The greenhouse bracket has the following characteristics:
1. The surface does not absorb moisture and does not return halogen. Through advanced modification technology and scientific production technology, the shortcomings of magnesite greenhouse pole, such as easy moisture absorption and halogen return, poor water resistance and easy deformation, were solved, which made it drip less frost and reduce pests and diseases in high temperature and high humidity environment.
2. Good durability. At present, most of the large scaffolding poles use metal frames and bamboo frames, and metal scaffolding is expensive and easy to rust; The life of bamboo scaffolding is very short, only a few years. The modified magnesite vegetable shed has low cost and long service life, and its comprehensive performance is attributed to the above two materials.
3. The application effect is good. The lighting surface of various types of modified magnesite vegetable greenhouses is designed into an arc shape, which improves the angle of the light transmission surface. There are no columns in the greenhouse, which reduces the shading. After entering the greenhouse, it is empty and bright, which is convenient for farming. Because the lighting surface is cambered, there is no dust accumulation, good light transmittance and high temperature in the shed. It was determined that the average temperature in the shed was 3℃ higher than that in the traditional bamboo pole cement shed, the yield was increased by 15~20%, and the harvest time was advanced.
4. The greenhouse has good weather resistance and low cost. The transformed magnesite vegetable shed is made of inorganic materials, and there is no aging problem. It can withstand wind, rain and sunshine all year round, and has good frost resistance and soil corrosion resistance. After the actual investigation of the greenhouse used for 5 years, there is no sign of damage. The investment of shed construction is much lower than that of metal shed and bamboo pole cement column shed, but its service life and maintenance management are better than the above two kinds of sheds. In recent years, the planting area of vegetables in greenhouse in warm winter has expanded rapidly year by year, and the application scope of low-cost and high-performance modified magnesite vegetable greenhouse will be wider and wider, bringing remarkable economic and social benefits to greenhouse vegetable producing areas.
