ສານເສີມຄອນກີດທີ່ມີນ້ໍາຫນັກເບົາ | ຕົວແທນ Foaming ປະສິດທິພາບສູງສໍາລັບຄອນກີດ Cellular
ຕົວແທນ Foaming ສໍາລັບ Foam Concrete ມີຜົນກະທົບທີ່ສໍາຄັນຫຼາຍຕໍ່ຄຸນນະພາບຂອງສີມັງ foamed. ຕົວແທນ Foaming ທີ່ມີຄຸນນະພາບສູງສາມາດເຮັດໃຫ້ສີມັງໂຟມທີ່ມີຄຸນນະພາບສູງ. ການປະຕິບັດຂອງຕົວແທນ Foaming ສໍາລັບ Foam Concrete ບໍ່ພຽງແຕ່ກ່ຽວຂ້ອງກັບເວລາສະຖຽນລະພາບແລະຄວາມເປັນເອກະພາບຂອງໂຟມເທົ່ານັ້ນ, ແຕ່ຍັງກັບຂະຫນາດຂອງຟອງແລະອັດຕາການເລືອດອອກ.
The foam diameter of ຕົວແທນ Foaming 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. ໃນຄວາມເປັນຈິງ, 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. ວັດຖຸດິບ ແລະ ສູດດຽວກັນ, ອຸປະກອນແລະເຕັກໂນໂລຊີດຽວກັນ, 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. ເພາະສະນັ້ນ, 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, ຫຼີກເວັ້ນການໃຊ້ໂຟມ້ໍານົມ
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. ໃນບັນດາພວກເຂົາ, 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) ເລືອດອອກຂອງໂຟມຂອງແຫຼວ. 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, ການລະບາຍຄວາມກົດດັນດ້ານ, and liquid film destruction drainage. ຮູບເງົາຂອງແຫຼວທີ່ຫນາກວ່າຂອງໂຟມ, 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, ມັນຈະບາງຄືກັບນ້ໍາທີ່ເລື່ອນໄດ້, turbulent flow, can not pile up, the amount of water in the foam is very large. ເມື່ອໂຟມປະເພດນີ້ຖືກເພີ່ມໃສ່ slurry ຊີມັງ, slurry ຊີມັງກາຍເປັນບາງຫຼາຍ, but the foam is very small, the volume of the slurry is small, and the foamed concrete produced has a high density, ທີ່ບໍ່ໄດ້ຕາມຄວາມຕ້ອງການດ້ານວິຊາການ.
ເພາະສະນັ້ນ, ໂຟມ້ໍານົມບໍ່ສາມາດໃຊ້ໄດ້. The appearance of the foam that meets the technical requirements should be spongy, fine and small bubbles, piled ຂຶ້ນ ຄື ຟັງ ສີ ຂາວ, like bounced cotton, ແລະຈະບໍ່ໄຫຼແບບສຸ່ມ. 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, ມີນ້ໍາພຽງເລັກນ້ອຍລະຫວ່າງຟອງ, 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, ແຕ່ເນື່ອງຈາກວ່າເສັ້ນຜ່າສູນກາງຂອງຟອງໃຫຍ່ເກີນໄປ, ມັນຍັງບໍ່ມີເງື່ອນໄຂ.
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, ນັ້ນແມ່ນ, it does not produce negative gelation effects. This cannot be achieved by all kinds of bubbles.
ໃນການທົດສອບໄລຍະຍາວ, we have found that many foams hinder the gelation of cement, magnesite and gypsum, ເຊິ່ງສາມາດຫຼຸດຜ່ອນຄວາມເຂັ້ມແຂງຂອງສີມັງໂຟມ, 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, ແຕ່ມັນບໍ່ເຂົ້າກັນໄດ້ກັບວັດສະດຸ gelling, 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.
