have exceeded the growth rate of 20%, especially in this year, when the epidemic prevention and control eased, the sales of gypsum mortar spraying machines after the resumption of work and production increased significantly compared with the same period last year, which is enough to say that the industrial by-product gypsum in the construction industry is no longer a standout from the building materials industry in the past, but an equal share with the construction field.
An Analysis of the New Application of Industrial By product Gypsum in the Field of Building Construction Pan Xiumei, Marketing Director of Wenzhou Construction Machinery Co., Ltd.
As a new green and environment-friendly building material, gypsum mortar has good workability, water retention, cohesiveness, and sufficient hydration of the slurry with gypsum as the base material, and is good at firmly bonding with different base materials.
The machine itself is equipped with a stator guide slide for separating the rotor from the stator, which makes it more convenient to disassemble the screw pump on the construction site.
The current construction equipment is JP90Z grouting and spraying dual-use machine.
It can be seen that our government has included it in the national key work.
The construction technology is divided into grouting method and spraying method.
According to the information released by the Ministry of Housing and Urban Rural Development last year, the proportion of prefabricated buildings in the new building area will reach 30% in the next 10 years.
The current application area is not only in the north, but also in the south.
[Abstract] This article focuses on the economic internal circulation in the post epidemic era, expanding infrastructure construction and real estate development to stimulate domestic demand, and accelerating the development of comprehensive utilization of resources.
Wall grouting construction of light steel keel villa wall spraying construction of light steel keel villa JP90Z is characterized by integrating mixing and pumping.
JP90Z Structure Diagram JP90Z Mixing System Components In addition, the mixing shaft is a rectangular tube and a right angle propeller seat, which makes the mixing mortar more stable and reduces maintenance costs.
The lower delivery pump of JP90Z has a discharge capacity of 130L/min and a delivery distance of 60m, which can pump gypsum mortar up to the villa roof with a three story structure.
At the same time, the water supply system of the mixer has the function of automatic metering water supply.
JP90Z Spraying Machine JP250 large displacement polyphenyl particle grouting machine “The best thing you can do is the best” JP90Z grouting and spraying dual-use machine has become an indispensable product of the construction of light steel keel villas in China.
Due to the progress of science and technology, the production technology of gypsum has been improved, and the output and quality of industrial by-product gypsum have been growing and improving.
At present, gypsum based mortar produced by by-product gypsum is mainly used in the field of building construction, such as plastering gypsum mortar, horizon gypsum mortar and high-strength gypsum mortar.
The dedusting screen is equipped with multiple air atomizers to eliminate a large amount of fugitive dust generated when powder is put into it, so as to protect the physical and mental health and safety of operators, and solve the problem that operators have abandoned their posts due to dust injuries in the past.
At present, it has been widely used in more than 20 provinces and cities in China, including Zhejiang, Hebei, Hunan, Xinjiang, Shaanxi, Ningxia, Anhui and Sichuan, playing an important role in the development of prefabricated buildings and beautiful rural construction in China.
Its physical properties can be comparable to that of cement-based mortar, and its operability is higher than that of cement-based mortar.
[Key words] Industrial by-product gypsum; Application process; Self leveling construction; Grouting of light steel keel villa; Wall plastering; In recent years, with the acceleration of China’s reform and opening up, the development of the national environmental protection circular economy has accelerated, and the comprehensive utilization and development of resources have achieved remarkable results.
With the rapid development and popularization of domestic light steel keel villas and the increase of industrial by-product gypsum production, rural light steel keel villas have become popular and will be popular with more people..
A number of spiral spray nozzles are set around the feed inlet to ensure that the inner wall of the mixer and the mixing blades are not sticky.
The application of various modified gypsum through deep processing in the field of building construction is becoming increasingly popular and widespread, not only limited to the building wall surface finishing engineering, but also extended to the deeper level of building engineering.
At present, provinces, cities and autonomous regions have intensively introduced new policies and regulations for the development of prefabricated buildings.
The horizontal mixer is placed on the upper part of the mortar delivery pump, and the large diameter outlet below is equipped with a fully closed discharge door.
The electric control system has program control, phase sequence protection and remote control functions.
Most of the walls of the light steel villas under construction and the light steel keel villas that have been built use the light thermal insulation mortar produced by industrial by-product gypsum as the filling material, and there is no lack of cement based light thermal insulation mortar, and the gypsum light thermal insulation mortar is emerging.
The internal mixing blade is a reverse discontinuous spiral structure, which circulates the mortar along the axial and radial directions at a certain angle, Because the blades formed by staggered arrangement turn over rapidly and violently to produce strong radial flow and axial flow, the contact surface between the mixture components is large, the size of micro aggregates is reduced, the encapsulation of micro aggregates is enhanced, and the full mixing is achieved, which is more suitable for the mixing of gypsum based mortar with high viscosity.
Therefore, the development and application of industrial by-product gypsum will be vigorously carried out, and the current situation, construction technology, equipment and prospect of industrial by-product gypsum application in various links of the construction field will be comprehensively described.
01 Gypsum based thermal insulation mortar applied to the wall grouting of light steel keel villas is in full swing.
With the aggressive construction of beautiful villages, light steel keel villas, as green buildings, have been praised by the people for their advantages of on-site assembly, short construction period, energy conservation and environmental protection.
What is more worth mentioning is that a dedusting screen is set on one side of the mixer.
The walls of light steel keel villas are mostly made of calcium silicate board or Eurozone board, and there are also stretched steel plate mesh as the template, and light steel profiles as the skeleton.
The output of desulfurization gypsum and phosphogypsum has accounted for more than 80% of the total industrial by-product gypsum, and industrial gypsum resources are increasingly rich.
In the past three years, the market sales of all kinds of gypsum based mortar construction machinery of Wenzhou Construction Machinery Co., Ltd.
This paper introduces the new application and new technology of gypsum mortar in construction field.
