Compared with traditional mortar and other products, gypsum-based lightweight plastering has the advantages of environmental protection, good construction performance, good adhesion, cost reduction, and construction period saving, which can solve the quality problems of traditional mortar such as easy cracking and shelling, and serve as a substitute for traditional mortar; At the same time, gypsum-based lightweight plastering can reduce the building load, adapt to the increasing trend of building height, and help adjust indoor temperature and humidity and improve living comfort; The practical activities of the engineering project show that the light putty powder project is convenient for construction, and the work can be carried out according to the required construction technology, and the actual effect of excellent interior and exterior wall putty can be obtained.
Gypsum-based light plastering is suitable for the walls of the room on the surface of rural base layers such as concrete, and is very suitable for the application of rural base floor leveling with large wall flatness errors, which greatly improves the ground leveling rate.
Gypsum-based lightweight plastering, also known as lightweight gypsum mortar, lightweight gypsum plastering mortar, lightweight sprayed gypsum, etc., is a new gypsum plaster material suitable for efficient leveling of indoor dry area walls and ceilings. The product is made of high-quality semi-water desulfurization gypsum as the main cementitious material, with green functional additives, made by a specific process, with high strength, strong adhesion, large application rate, anti-empty drum and anti-cracking. It can widely replace traditional cement mortar leveling, used for plastering and leveling of building interior walls and floors in indoor dry areas, and is suitable for plastering and leveling of most base materials (aerated blocks, brick walls, concrete walls and ceilings).
The so-called gypsum-based light plastering, in fact, is one of the types of stucco gypsum, with light microbeads as the main raw material, and then add an appropriate amount of additives, and finally through the technical process, become a new type of plastering material, with very excellent environmental performance, and very durable, compared with ordinary cement mortar, not only has the strength of cement mortar, but also durability is also excellent, including the price will be more advantageous, and even some users, directly used to replace cement mortar.
1. Low construction cost, according to construction workers, under the same circumstances, compared with ordinary cement mortar, the price of light gypsum will be lower, so in terms of cost, the cost is relatively low.
2, the thermal conductivity is small, according to professionals, after the light gypsum cures, its thermal conductivity is less than 0.15, only one-sixth of the cement mortar, if the interior wall is painted with light gypsum, you can do less part of the insulation layer, thereby reducing the thickness of the insulation layer and reducing the difficulty of construction.
3, the weight is very light, from the name can be seen, light gypsum texture is definitely light, according to the survey, a ton of light gypsum can normally be smeared 140 square meters, not only can reduce the load weight of the building, but also can effectively avoid empty drums, cracking and other situations.
4. Convenient construction, light gypsum can be finished and painted, but also by spraying, the construction quality is high, and can effectively accelerate the construction progress and reduce labor intensity
Heavy stucco plaster is mainly sand-based, light plaster plaster is mainly gypsum-based, which is an intuitive understanding from the heavy and light, in terms of construction thickness, heavy gypsum single batch of about 0 .6cm, heavy gypsum construction is too thick easy to fall, cracking, etc., light gypsum is different, a single time can reach about 1cm, while light gypsum is more viscous will not appear empty drum, fall and other situations.
Peculiarity:
Heat insulation, fire insulation, sound insulation, impact resistance, large adhesion, not easy to pulverize, no cracking, no empty drum, no powder
Scope of application:
It is suitable for all kinds of internal wall base layer plastering leveling, and is not suitable for wet, dry and wet cycle projects.
Lightweight bottom plaster plaster, also known as "stucco plaster" and "plastered gypsum mortar", is a new, environmentally friendly and economical new plastering material that replaces cement mortar.
It not only has the strength of cement, but also is healthier and more environmentally friendly and durable than cement, and is a binder for building gypsum, a new type of plastering material with light microbeads as aggregate and a variety of admixtures.
Performance characteristics of lightweight plastered plaster:
1. Green environmental protection;
2. Strong adhesion, no falling off, small shrinkage, no empty drum, no cracking;
3. Good adhesion and heterogeneity, convenient construction, less falling ash, fast operation;
4. Fast strength growth, easy drying, faster construction progress, suitable for large plastering volume, especially suitable for projects with tight construction period;
5. It has a certain thermal insulation effect, which helps to adjust the indoor temperature;
6. Light weight and low bulk density (≤1000kg/m³) can significantly reduce project costs and reduce construction loads.
Technical indicators:
The bottom plaster meets the requirements of the national GB/T28627-2012 "plastered plaster", and the main indicators:
Reference dosage: 1cm thick 8-9kg/m²
