Apar-sorgailuen teknologiaren printzipioak eta motak

Zer da apar-sorgailua?

Apar-sorgailua edozein dela ere, espumatzearen oinarrizko printzipioa apar-agentearen soluzioan airea sartzea da. Aldaketa mota desberdinak gasa sartzeko moduan desberdinak dira, beraz, eragina ere ezberdina da.

Beharrezko bi faktore daude aparra sortzeko, one is the foaming agent solution, eta bestea airea da. Both are indispensable. Puzte-agente soluziorik gabe, the liquid film surrounding the gas would not form and there would be no bubbles. And without gas, foaming agent solution alone cannot form bubbles.

In the bubble formation system, the blowing agent solution is the dispersion medium, the gas is the dispersed phase, and the gas is dispersed in the liquid to form bubbles, and then numerous bubbles form the foam. In addition to the important factor of blowing agent performance, the introduction of gas into the blowing agent solution is another important factor. The principle of the foam generator is to introduce gas into the liquid, hau da, the foam generator uses a certain method to introduce the gas into the liquid. Different foaming machines have different methods of introducing gas. Oro har, there are several ways to introduce gas into the foaming machine:

(1) Poliki-poliki biratzen diren palek gasa sartzen dute. Gasa morteroan zuzenean sartzeko metodo bat da (edo hormigoizko minda) zementuzko apar-agentearekin nahastuta. Nahasgailuaren palak minda bultzatzen duenean, airea minda sartzen da nahasgailuen palekin. Horrez gain, minda iraultzean aire kantitate handi bat sartzen da minda, eta airearen zati bat mindara eramaten dute zementuak eta agregatuak. Hiruren batura mindara sartzen den aire kantitate osoa da. Horien artean, nahaste-palak mindara sartutako aireak eta minda birakatuz palak bildutako aireak gorputz nagusia hartzen dute.

Airea minda sartu ondoren, apar-agente surfaktantea duen likidoak airea inguratzen du, elektroi-geruza bikoitzeko film likidoa eratuz airearen eta likidoaren arteko interfazean, and finally forms the bubbles in the slurry in the form of air-in-liquid.

Due to the slow rotation speed of the blades and less gas introduced in this way, the amount of bubbles generated is small, the foaming effect is not good, and the efficiency is low.

(2) High-speed rotating blades introduce gas. This is a way of introducing gas into the blowing agent solution by relying on high-speed rotating blades. The introduction of the gas mainly depends on the force of the rotating blades. The blades of this type generally require high-speed rotation, the speed should be> 700 rpm, orokorrean artean 700 eta 1400 r/min, and the peripheral speed of the impeller end should be> 20 m/s in order to obtain satisfactory results. A certain high speed can expose the impeller to the liquid, contact with air, and introduce air. If the speed is too low, bultzatzailea ez da likidoaren eraginpean egongo, eta odoljario-kopurua oso txikia izango da. Abiadura egokia likidoa biratzen ari denean bultzatzailea agerian dagoena baino txikiagoa izan behar da.

(3) The use of pressure to introduce gas. This is the most commonly used advanced air-entrained foaming method at home and abroad. Gainera, airea sartzeko metodo zientifikoagoa da. It is the core of the foam concrete high-pressure and medium-pressure foam generator technology.

The two methods mentioned above are slow and uneven, and the bubble diameter is large, especially the bubble diameter cannot be controlled. It is completely dependent on the randomness of the foaming machine, and cannot guarantee the small bubble diameter and uniform foam. The most critical technical indicators. Aldi berean, the amount of foaming is difficult to control.

In order to effectively solve the above problems, the pressure-entrained foaming method came into being. No matter in terms of foaming volume, foaming speed, foam diameter and foam uniformity, etab., they have stepped on a new level and have made great technological progress. Bere printzipio nagusia airearen presioa sor dezaketen hainbat ekipamendu erabiltzea da, airea fase likidoan sartzeko, bi faseen nahasketa uniformea ​​lortzeko.. Presio arruntean, zaila da airea likidoan sartzea, baina presio jakin baten pean, errazagoa bihurtzen da. Aire-presio honek gasa likidoan sartzen ez ezik, baina baita likidoa gasean sartzen. Izan ere, aldi berean presioa egiten du. Modu honetan, bi faseen nahasketa azkarra izango da, eraginkorra, uniformea, eta burbuila finak dituzte, aparraren baldintza tekniko ezin hobeak betetzen dituena.
