فوم ڪنڪريٽ جي تياري - جسماني فومنگ

فوم ڪنڪريٽ is a new type of lightweight thermal insulation material which contains a large number of pores by foaming the foaming agent by mechanical means or compressed air method, then mixing and mixing with the cement mortar, and passing through the pumping agent or artificial cast-in-place construction.Foamed concrete is a porous building material with good thermal insulation and shock absorption properties. Due to its structural characteristics, foam concrete has the advantages of light weight, گرمي جي حفاظت, گرمي موصليت, آواز جي موصليت, fire resistance and good seismic performance.

Physical foaming, اهو آهي, mechanical foaming, is introduced into the air by mechanical agitation or shearing, and air is encapsulated by an aqueous solution of a surfactant or a surface active material. The physical foaming process does not produce new substances for physical use, and the bubble diameter can be controlled by the shear rate. Physical foaming forms uniform and stable bubbles, and the type of blowing agent determines the quality of the foamed concrete. في الحال, physical foaming mainly utilizes an air compressor as an instrument to drive air into a foaming agent solution, a foaming agent solution into a foam, and then mixing the slurry and the foam to obtain a foamed concrete. Physical foaming can be used to adjust the properties of foam concrete by controlling the amount of blowing agent incorporated.

The principle of the compressed air method is mainly to use pressure to drive air into the foaming agent solution to form a foam.

في الحال, the commonly used physical foaming agents mainly include: resin صابن foaming ايجنٽ, سبزي پروٽين فومنگ ايجنٽ, petroleum sulfonic acid aluminum foaming agent, جانورن جي پروٽين foaming ايجنٽ, hydrolyzed blood gelling foaming agent, rosin acid soap foaming Agents, وغيره.

From the chemical composition point of view, physical foaming agents mainly include surfactants and proteins. The more polar groups in the surfactant structure contain hydrophilic groups, the stronger the hydrophilic action, and the better the bubble performance.

بهرحال, the surface layer of the foam has a large water content, which deteriorates the stability of the foam. ساڳئي وقت ۾, surfactant سيمينٽ جي ذرات سان لهه وچڙ ڪري سگهو ٿا, hinder the hydration reaction and reduce the strength of the foam concrete.

The white matter-based foaming agent generates a small molecule by breaking the peptide bond, and increases the hydrophobic group to form an interface. ان کان علاوه, hydrogen bonds are formed between the specific groups in the molecule, so that the solution forms a foam film with higher strength.

ان کان علاوه, hydrogen bonds are formed between the specific groups in the molecule, so that the solution forms a foam film with higher strength.

The vegetable protein foaming agent is dissolved in water and is hardly affected by the hardness of water, ۽ غير زهر آهي, بي بوءِ, and has a strong foaming ability, and the foam is fine and rich. بهرحال, the stability of the foamer product is poor, and the foam stabilization time is short and large-scale use cannot be achieved.
