What is the specific function of lightweight plastering plaster, and how is it constructed?

There are many types of gypsum, mainly used for building walls and floors. At present, light plastering plaster is widely used for the construction of wall leveling. What is the role of lightweight plastering plaster and how to construct it? Follow me to see it. The role of light plastering plaster During the construction of light plastering plaster, sprinkle water or interface agent on the wall surface, and then do the reinforcement construction. The thickness of the reinforcement reinforcement is generally 1 cm. It is appropriate to control it at 5-6 mm. After the gypsum plastered on the wall is formed, the remaining light plastering plaster is scraped and smoothed as a whole to meet the construction requirements of flatness. Construction method of lightweight plastering plaster According to the normal construction steps, the construction can effectively avoid the phenomenon of hollowing and cracking of the wall. 1. Clean the dust, dirt, oil stains, release agent and other substances on the base surface. 2. Wet the base surface, wet the base surface with water, and then treat the roughness of the base surface with an interface agent. 3. Different material base surfaces need to be laid with glass fiber mesh, and the width needs to be between 150~300mm of the overlap width of each base. 4. Light plastering gypsum needs to be used within half an hour after stirring, and the gypsum after drying cannot be mixed with water. 5. The thickness of smear is (5-25)mm can be used once, and (25-35)mm can be divided into two times. 6. The indoor construction temperature in winter is above 5 degrees, and in summer, it is high temperature and windy, so doors and windows should be closed. 7. Reinforcing bar requirements: when the height of the wall is ≤3.5m, make strong bars, and the distance between the two bars is ≤1.5mm; when the height of the wall is >3.5m, it is advisable to make horizontal bars, the distance between the two bars is ≤2m, and the width of the bars is 30mm-50mm. 8. The gypsum slurry shall not be exposed to moisture and rain. What is the specific function of lightweight plastering plaster, and how is it constructed? Features Compared with cement, its durability will be better, and its environmental protection is good, green and non-toxic to use; it has strong cohesion, small shrinkage, not easy to fall off, not easy to hollow, not easy to crack; its construction It is convenient, less ash on the ground, and quick to operate; its strength increases quickly, it is easy to dry, it can speed up the construction progress, and it is suitable for projects with a large amount of plastering and a tight construction period; it also has good thermal insulation, which helps to adjust the indoor temperature. Precautions Lightweight plastering plaster has the characteristics of light weight, fire resistance, moisture resistance, easy processing and simple installation. Lightweight plastering plaster is mainly used for plastering and thermal insulation of walls and floors (aerated bricks, brick walls, concrete walls, roofs) in dry areas. The thickness of the wall construction is 6-20mm, and the total thickness of the top plaster is less than 10mm. In order to prevent excessive drying, gypsum powder should not be mixed with other substances. In summer construction or drywall construction, water should be wetted before construction. The suitable construction temperature is 5-40 degrees Celsius, avoid rainy days, high temperature and frosty weather construction. After the lightweight plastering gypsum is set, its strength increases with the decrease of water content, and it can be coordinated with the characteristics of slow water absorption of air-entrained concrete to produce good overall strength. Lightweight plastering gypsum has good moisture-removing properties. After drying, it has a good moisture-removing effect on the drying of aerated concrete, avoiding various disadvantages caused by uneven water content in the aerated concrete.

The solution to the problem of stones in mortar is recommended by the manufacturer of dry powder mortar equipment

The solution to the problem of stones in mortar is recommended by the manufacturer of dry powder mortar equipment The stone problem refers to a large number of stones in the mortar, which seriously affects the service performance of the mortar, so how to solve it? Dry powder mortar equipment manufacturer to let you know Strictly clean the sand in the machine Strengthen the working awareness of forklift drivers to avoid mixing stones when shoveling sand Try to avoid too close distance between different material buckets, and ensure that the sand bucket wall is not perforated to ensure that materials will not be mixed The sand silo and belt shall be strictly cleaned The manufacturer of dry powder mortar equipment suggests to regularly check the screen of sand screening machine to avoid sand quality fluctuation after damage Viscosity is also a parameter to reflect whether the mortar is easy to use. The mortar with normal viscosity is smooth in construction and is not easy to fall off on the wall. When the viscosity is not good, the mortar looks scattered, which is difficult to construct. When the viscosity is too good, the mortar is not easy to dry on the wall, and the worker sticks the scraping ruler when rubbing and pressing, which will also be difficult to construct. The viscosity of mortar will increase in winter, and the amount of viscosity adjustment admixture should be reduced accordingly. When the temperature is high in summer, the viscosity of mortar will decrease and the amount of admixture will increase accordingly. Generally, the dosage of admixture shall be increased or decreased by about 1kg / m3 for every 5 degrees increase or decrease in temperature Stone powder also has a great impact on mortar viscosity. Too many impurities in stone powder will show too low whiteness. When used in mortar, there will be poor mortar viscosity and mortar bleeding It is better to control the whiteness of stone powder above 40 degrees. Too low whiteness means that there are too many impurities, which has a great impact on the quality of mortar. Solution to dry and hard mortar: We should also consider the change of climate and environment and appropriately adjust the dosage of regulator. To achieve the same opening time, the higher the temperature, the greater the amount of regulator. In principle, the opening time of masonry mortar shall be adjusted to be 3 ~ 4 hours longer than that of workers, and the opening time of plastering mortar shall be 1 ~ 2 hours longer than that of workers. The opening time of ground mortar shall be determined according to the actual construction operation on the site (the shorter the opening time is, the better on the premise of meeting the use requirements)

What are the selection methods of dry mix mortar additive cellulose?

One of the biggest differences between dry mix mortar and traditional mortar is the modification of dry mix mortar with a small amount of chemical additives. Adding one additive to dry mortar is called primary modification, and adding two or more additives is secondary modification. The quality of dry powder mortar depends on the correct choice of ingredients and the coordination of various ingredients. Because chemical additives are more expensive and have a greater impact on the performance of dry mortar. Therefore, when selecting additives, the amount of additives should be given top priority. The following is a brief introduction to the selection method of chemical additive cellulose ether. What are the selection methods of dry mix mortar additive cellulose? Cellulose ether, also known as rheology modifier, is an admixture used to adjust the rheological properties of fresh mortar and is used in almost every type of mortar. The following properties should be considered when selecting its variety and addition amount: (1) Water retention at different temperatures; (2) Thickening effect, viscosity; (3) The relationship between consistency and temperature, and the influence on consistency in the presence of electrolyte; (4) The form and degree of etherification; (5) Improvement of thixotropy and positioning ability of mortar (this is necessary for mortar painted on vertical surfaces); (6) Dissolution rate, conditions and completeness of dissolution. In addition to adding cellulose ether (such as methyl cellulose ether) to the dry powder mortar, polyvinyl acetate can also be added, that is, secondary modification. Inorganic binders (cement, gypsum) in mortar can ensure high compressive strength, but have little effect on tensile and flexural strength. Polyvinyl acetate establishes an elastic film in the cement stone pores, so that the mortar can withstand high deformation loads and improve wear resistance. Practice has proved that adding different amounts of methyl cellulose ether and polyvinyl acetate into dry mortar can prepare thin-layer smeared slab bonding mortar, plastering mortar, decorative plastering mortar, and masonry mortar for air-entrained concrete blocks And self-leveling mortar for pouring the floor, etc. Mixing the two can not only improve the quality of the mortar, but also greatly improve the construction efficiency. In practical application, in order to improve the comprehensive performance, a variety of admixtures are required. There is an optimal matching ratio between the additives. As long as the dosage range and ratio are appropriate, they can improve the performance of the mortar from different sides. However, when they are used alone, the modification effect of the mortar is limited, and sometimes even Negative effects, such as single-mixing cellulose, increase the cohesion of the mortar and reduce the degree of delamination, but at the same time, the water consumption of the mortar is greatly increased and the mortar is stored in the interior of the slurry, which leads to a greater decrease in the compressive strength; When the air-entraining agent is added, although the stratification of the mortar can be greatly reduced and the water consumption can also be greatly reduced, the compressive strength of the mortar tends to decrease due to more air bubbles. In order to maximize the performance of masonry mortar and avoid harm to other properties of the mortar, the consistency, layering and strength of the masonry mortar can meet the engineering requirements and relevant technical specifications. It is necessary to take comprehensive measures, develop and use composite admixtures from the perspectives of water reduction, viscosity enhancement, water retention and thickening, and air-entraining plasticization for cement and environmental protection.

INTRODUCTION OF ADVANTAGES AND DISADVANTAGES OF DRY POWDER MORTAR AND WET MIXED MORTAR

1. Advantages and disadvantages of wet mixed mortar Wet mixed mortar is a ready mixed mortar that measures and mixes raw materials such as cement, fine aggregate, mineral admixtures, admixtures, additives, pigments and water in a certain proportion in the mixing plant, and then transports them to the construction site through a transport vehicle with mixing device for use, which is required to be used up within the specified time. The quality is stable and the supply quantity is large at one time. After arriving at the site, the mortar is stored first, and then the construction workers manually lay the mortar on the base material. Wet mixed mortar is produced in concrete mixing plant, which has the characteristics of accurate measurement and fast production speed. Wet mixed mortar is a kind of mortar mixture, and its use time is limited, so it must be used up within a certain time after production. These characteristics of wet mixed mortar also show its advantages and disadvantages in development. Its advantages are as follows: （1） Industrialized production is conducive to quality control and assurance; （2） Large one-time supply, especially suitable for bridge pavement leveling layer construction, layer waterproof construction and other projects; （3） There is no need for on-site mixing, which saves the expenses of drying equipment and packaging equipment; （4） The construction site has good environment and less pollution; （5） There is a wide choice of raw materials. The aggregate can be dry or wet without drying, which reduces the cost; （6） It can be mixed with a large amount of industrial waste residue such as fly ash, which can not only save resources, but also reduce the cost of mortar. Of course, it also has many disadvantages in production and use: （1） Since it is well mixed by professional manufacturers, it needs to be stored in closed containers on site, and the one-time transportation volume is large, which must be used up in a limited time, so it is impossible to flexibly control the consumption according to the construction progress; （2） There is a large amount of one-time transportation, so it is inevitable to store it in closed containers on site. Over time, it will have high requirements on the workability, setting time and stability of working performance of mortar; （3） The time of transportation is restricted by traffic conditions. 2. Advantages and disadvantages of dry mixed mortar Dry mixed mortar is a kind of ready mixed mortar, which is made of various dry raw materials in a certain proportion, accurately configured and mixed by the factory, transported to the construction site in bags or bulk, and mixed with water or supporting components in the specified proportion at the place of use. Therefore, compared with the wet mixed mortar, it is not limited by the use time and quantity, so it is the leading direction of the development of ready mixed mortar. Dry mixed mortar has many advantages: （1） The production efficiency is high. Because it is transported in the silo, automatically stirred, pumped and mechanically applied mortar, its production efficiency reaches 500% – 600% of the traditional production efficiency; （2） The mechanized mixing of construction efficiency can ensure the correct treatment and construction of mortar, so as to avoid the occurrence of too much or too little mixing water and wrong formula; （3） Mortar has many varieties, excellent quality, stable performance and convenient application; （4） Economic benefits dry mixed mortar has good sand grading and small particle size. On the premise of ensuring the quality, the thickness of mortar can be reduced and the construction dosage can be reduced; （5） Social benefits dry concrete mortar has realized the management system of integration of production, circulation and supply, which represents the industrialized production direction of new building cementitious materials. In addition, it can be used immediately with water, the operation is mechanized, the recognized working conditions are improved, and the labor productivity is improved. However, dry mixed mortar still has the following disadvantages: （1） The investment of dry powder mortar production line is relatively large, and the investment of bulk tanks and transportation vehicles is also large; （2） Because the raw materials are mixed by dry raw materials, there are high requirements for the moisture content of materials, so there are certain restrictions on the selection of raw materials; （3） Site water mixing is required during construction, so there are high requirements for the professional technology of material mixing personnel; （4） In the process of storage and pneumatic conveying, it is easy to produce material separation, resulting in uneven mortar.
