軽量コンクリート添加剤 | 気泡コンクリート用高性能発泡剤
発泡コンクリート用の発泡剤は、発泡コンクリートの品質に非常に重要な影響を与えます。. 高品質の発泡コンクリートを製造できる高品質の発泡剤. 発泡コンクリート用発泡剤の性能は、泡の安定化時間と均一性だけではありません。, 泡の大きさや出血速度にも影響します.
The foam diameter of 発泡剤 for Foam Concrete is not as big as possible, it should be about 1mm
The pores have the same requirements for the pore diameter, and the same should be the same for the bubble diameter. Many producers ask the foam pore size to be as small as 0.1mm. 実際には, it is because if the physical foaming has a large foam diameter, the stability of the foam is poor and foamed concrete cannot be made. 原材料も配合も同じ, 同じ設備と技術, just change the bubble diameter, the compressive strength of foam concrete with 1mm bubble diameter is at least 20% higher than that of foam concrete with 0.1mm bubble diameter. したがって, it is wrong to pursue a large bubble diameter of 0.1mm or more. It is a misunderstanding in the production of foam concrete and should be corrected.
Foaming Agent for Foam Concrete's foam bleeding rate is as low as possible, 乳白色の泡の使用は避ける
According to the size of water content, foam is divided into milky foam with more water and less foam and sponge foam with more and less water. その中で, milky foam is unqualified and inferior foam and cannot be used.
After the foam of the Foaming Agent for Foam Concrete is produced, it gradually oozes water. The bleeding consists of two parts:
(1) Bleeding of foam liquid film. This part of water is secreted from the liquid film, which is the water secreted by the liquid film under the combined action of gravity drainage, 表面張力排水, and liquid film destruction drainage. 泡の液膜が厚ければ厚いほど, the greater the bleeding; the faster and more the foam bursts, the greater the bleeding.
(2) Water between bubbles. This part is water with no bubble liquid film formed. The worse the foaming performance of Foaming Agent for Foam Concrete and the foaming machine, the more water between the bubbles that cannot form a foam liquid film. They are actually water that can't become bubbles.
When the bleeding rate of the foam is high, 浮いた汁のように薄くなる, turbulent flow, can not pile up, the amount of water in the foam is very large. When this kind of foam is added to the cement slurry, セメントスラリーは非常に薄くなります, but the foam is very small, the volume of the slurry is small, and the foamed concrete produced has a high density, which does not meet the technical requirements.
したがって, ミルキーフォームは使用できません. The appearance of the foam that meets the technical requirements should be spongy, fine and small bubbles, piled up like white clouds, like bounced cotton, ランダムに流れることはありません. The water content of this foam is very small. This shows that its foam liquid film has little bleeding, the foam is not easy to burst, 泡の間には水がほとんどない, and the amount of bubbles is large, and most of the volume is air bubbles. What needs to be emphasized here is that the sponge foam must be small bubbles with a bubble diameter of less than 1mm, not large bubbles of a few millimeters or even tens of millimeters. Large bubbles are easy to pile up, and they look like white clouds, でも気泡径が大きすぎるので, それも無資格です.
The low bleeding of foam is required to ensure the number of bubbles in the foam and the porosity of the foam concrete, which is to ensure the density of the foam concrete.
The foam of Foaming Agent for Foam Concrete has no side effects on cementitious materials
Cementitious material is the main source of the strength of foam concrete. The addition of Foaming Agent for Foam Concrete cannot affect its gelation, つまり, it does not produce negative gelation effects. This cannot be achieved by all kinds of bubbles.
In long-term tests, we have found that many foams hinder the gelation of cement, magnesite and gypsum, which can reduce the strength of foamed concrete, and sometimes even the hardened concrete basically loses its strength. The stability of these foams is very good. It lasts for a few hours. It looks like a sponge, has low bleeding, and has a uniform density. It meets the technical requirements in all aspects, but it is not compatible with the gelling material, so it cannot be used in production. . This shows that foams that are qualified in other aspects, such as the impact strength, are ultimately not technical requirements.
