01:High fire resistance

Gypsum is a fireproof building material recommended by the state. It has superior fireproof performance and is a non-combustible A1 inorganic material.

Gypsum has a large amount of crystal water (about 21% by weight) after it is condensed. The crystal water can be released first under heated conditions. The formed water vapor can effectively prevent the flame from spreading. The dehydration process can absorb a lot of heat. Delay the time for the wall to heat up and control the degree of damage to the building from the fire.

02:Good comfort

Comfort performance refers to the "breathing function" of the cast. "Respiratory function" refers to the function of automatic adjustment of indoor air humidity with plaster. Plastering gypsum forms a microporous structure after hardening. The microporous structure of gypsum consists of intersecting needle-shaped crystals of dihydrate gypsum. Therefore, there is a large amount of free space in the needle-shaped crystal structure, and its porosity is high. When the air humidity is high, gypsum can absorb the moisture in the air through the capillary structure; on the contrary, when the humidity in the air is low, the gypsum can also release the moisture in the capillary structure by repeating the cycle to automatically adjust the indoor air. The role of humidity, "warm in winter and cool in summer", makes the living environment more comfortable.

03:Thermal insulation

"Warmness", using plaster to make the wall feel warm.

The thermal conductivity of plastering gypsum is similar to that of wood, about 0.28w/m.k. The thermal conductivity of cement mortar is about 0.87w/m.k. Gypsum products have good thermal insulation properties. The wall surface after plaster construction can be soundproofed by 20-50 decibels. At the same time, it is a good sound-absorbing material. It is insulated in winter and in summer, which can create a comfortable working and living environment.

04:High health performance

Plaster plaster is moisture-proof, mildew-proof, environmentally friendly, and formaldehyde-free. The PH value of plaster products is neutral (about 7, cement mortar is about 11-12, strong alkaline), healthy and environmentally friendly.

Condensed water is easy to form on the surface of cement mortar wall, which will increase indoor moisture. Due to the instability of the raw materials of sand and other additives, many radioactive substances or formaldehyde will be produced, which seriously endanger human health. Gypsum mortar is the best for healthy home Interior wall materials.

Gypsum is biologically soluble and will not affect health if inhaled. The bio-solubility of gypsum is 2.5 g/L, and that of limestone is 0.3 g/L. Silica sand will not be absorbed by the human body. Cement can seriously affect health if inhaled.

05:Good environmental performance

The production of one ton of gypsum powder emits about 0.14 tons of carbon dioxide, which is only one-tenth of that of cement (cement emits about 1 ton of carbon dioxide), and sulfur dioxide emissions are only one-twentieth of that of cement-low carbon, energy saving and environmental protection.

Gypsum building materials waste can be recycled, after being crushed, screened, and calcined, it can continue to be processed as a raw material. It is a typical reusable environmental protection material.

06:Excellent physical properties

Plastering gypsum has strong adhesive force and is more effective when used on substrates such as aerated concrete and cast-in-place concrete. The plaster layer will not appear hollow cracking.

Plastering gypsum has excellent workability, fluidity and water retention properties, easy to collect light, after plastering, the wall is dense, smooth and delicate, without sand, high strength, without shrinkage, no hollowing, no cracking, and no smell , Without any radiation.

07:Low construction cost

Plastering plaster sets and hardens quickly. The surface layer can be plastered 1~2h after the bottom layer is finished. It is not necessary to wait for the base layer to dry before the surface layer construction, which is beneficial to the early intervention of the later process. It can greatly speed up the progress of project construction; due to the high bonding strength, it is suitable for mechanized spraying construction, can be well bonded with any substrate, and can be free from thickness restrictions, convenient and fast construction, and high construction efficiency.

Lightweight plastering plaster has low density and can get more finished surface. And it can wipe 6 ~ 35mm at a time, a single layer can achieve a smooth surface, no need to batch putty and other materials,-on the one hand, save material costs, on the other-reduce the construction process, speed up the construction progress, and save the construction cost.
