The foam diameter of Foaming Agent 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. Ni pato, 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. Awọn ohun elo aise kanna ati agbekalẹ, kanna itanna ati imo, 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. Nitorina, 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, yago fun lilo foomu wara
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. Lára wọn, 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) Ẹjẹ ti fiimu omi foomu. 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, idominugere ẹdọfu dada, and liquid film destruction drainage. Awọn nipon fiimu omi ti foomu, 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, yoo jẹ tinrin bi oje lilefoofo, turbulent flow, can not pile up, the amount of water in the foam is very large. Nigbati iru foomu yii ba wa ni afikun si simenti slurry, slurry simenti di pupọ, but the foam is very small, the volume of the slurry is small, and the foamed concrete produced has a high density, eyi ti ko ni pade awọn ibeere imọ-ẹrọ.
Nitorina, foomu wara ko ṣee lo. The appearance of the foam that meets the technical requirements should be spongy, fine and small bubbles, kó jọ bí ìkùukùu funfun, like bounced cotton, ati ki o yoo ko ṣàn laileto. 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, omi kekere wa laarin awọn nyoju, 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, ṣugbọn nitori iwọn ila opin ti nkuta ti tobi ju, o jẹ tun unqualified.
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, iyẹn ni, it does not produce negative gelation effects. This cannot be achieved by all kinds of bubbles.
Ni awọn idanwo igba pipẹ, we have found that many foams hinder the gelation of cement, magnesite and gypsum, eyi ti o le din agbara ti foamed nja, 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, sugbon o jẹ ko ni ibamu pẹlu awọn gelling awọn ohun elo ti, 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.
